Salute The 14th Miklós Iványi International PhD & DLA Symposium is one of the most important scientific events at the Faculty of Engineering and Information Technology, University of Pécs. The Faculty hosts the meeting for young researchers and their professors. After the loss of the founder of this Symposium, Prof. Miklós Iványi, it has been decided to honour his memories and therefore this event will be named as “Miklós Iványi International PhD & DLA Symposium”. This is the 14th year that the PhD & DLA Symposium gives an opportunity to present the achievements of young researchers, to exchange information about the researches of the international partner institutions and to exchange valuable professional experiences and cultivate real friendships. At the end let me greet the participants of the 14th Miklós Iványi International PhD & DLA Symposium and express my thanks to the organizers for their activity and to the participants of the former and this year’s PhD & DLA Symposium to present papers. At the same time I wish you the best to continue with successful work.

Prof. Dr. Habil MEDVEGY Gabriella, DLA Dean Faculty of Engineering and Information Technology University of Pécs

Foreword The 14th Miklós Iványi International PhD & DLA Symposium is organized because it is thought that PhD&DLA students need a special forum in addition to their PhD&DLA program to present the results of their ongoing research. Furthermore the results should be discussed collecting proposals how to continue the work. The First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Nineth, Tenth Eleventh, Twelfth and Thirteenth International PhD&DLA Symposia were organized in 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 and 2017 and it is important to continue this tradition. Objectives of the PhD&DLA Symposium: • to provide a forum for PhD&DLA students in engineering to present the progress of their work; • to discuss the results of the ongoing PhD&DLA studies in order to support the future activity; • to give the opportunity for PhD&DLA students to establish contact for international communication; • to compare PhD&DLA studies in various countries. The system of this symposium is to have oral presentations by the PhD&DLA students themselves, which are immediately followed by discussions that are scheduled in the program. Main results of the studies are summarized in the Pollack Periodica (an International Journal for Engineering and Information Sciences) published by Akadémiai Kiadó. On behalf of the Organizing Committee, I would like to express thanks to the University of Pécs, Faculty of Engineering and Information Technology for hosting the Symposium. Prof. Dr. Habil Péter IVÁNYI, PhD

On the interdisciplinarity of geometry STACHEL, Hellmuth Institute of Discrete Mathematics and Geometry, Vienna University of Technology

From the ancient Greeks to 21st century developments, Geometry plays a fundamental role in different sciences. Either, geometric theorems contribute directly to different academic disciplines, or visualizations make theories more transparent and pave the way to new results. The goal of this lecture is to elucitate this in form of a picture book with a series of examples. Furthermore, we also want to highlight the role of Geometry in education and recall, that in a graphics-oriented world a specific training of spatial ability is inevitable for many professions.

An energy-based approach to the analysis of no-tension masonry-like structures BRUGGI, Matteo Department of Civil and Environmental Engineering, Politecnico di Milano

The so-called “linear elastic masonry-like” material model allows investigating the equilibrium of structures with negligible strength in tension relying solely on a survey of the geometry and a minimal characterization of the material. This model assumes that the stress tensor is negative semi-definite and depends linearly upon the elastic part of the strains. Cracks are described by inelastic strains that can possibly arise orthogonally to the principal compressive directions. Notwithstanding the apparent simplicity of the above assumptions, several issues must be dealt with when finite elements and incremental approaches are implemented to solve the no-tension equilibrium. An energy-based approach is presented to perform the analysis of 2D and 3D no-tension masonry-like structures exploiting methods and formulations commonly used in structural optimization. Masonry is replaced by a suitable equivalent orthotropic material with spatially varying elastic properties and negligible stiffness in case of cracking strain. An efficient non-incremental algorithm is implemented to define the distribution and the orientation of the equivalent material, minimizing the overall strain energy while enforcing a compression-only state of stress. The algorithm can be straightforwardly implemented in any finite element software package for the linear elastic analysis of orthotropic materials that is endowed with an application programming interface. The proposed method visualizes no-tension stress flows in masonry structures subject to compatible loads and settlements. It computes failure mechanisms in agreement with limit load analysis, without any a-priori hypothesis regarding the collapse mode. Applications are shown addressing walls acted upon by dead loads and both in-plane and out-of-plane seismic loads, arches and vaults. An extension to the design of the optimal reinforcement to retrofit no-tension masonry-like structures is outlined.

Writing and Publishing Journal Papers: Why, How, Tips, Techniques and Targets TOPPING, Barry H.V.1,2,3 1

Emeritus Professor of Computational Mechanics, Heriot-Watt University, Edinburgh, Scotland, UK Honorary Professor, University of Pécs, Hungary 3 Co-Editor: Computers & Structures and Advances in Engineering Software 2

This short presentation highlights how journal publication in the course of a programme of doctoral research can improve research methods and lead to an enhanced doctoral thesis. It discuses key elements of how research leading to the award of a PhD may be managed and how journal publication can become a key management tool available to both the researcher and supervisor. The presentation then covers the role of publishers, editors, editorial boards and reviewers of international journals. The ethics of paper writing are briefly mentioned. The key features of journal paper writing and submission are described. The generic structure of technical papers is highlighted and common pitfalls that the researcher should be aware of before attempting the writing and submission of journal papers are described. The importance of selecting the most appropriate journal is emphasised. Many journal submissions fail to pass to the review stage of the submission process and many other submissions fail unnecessarily. The presentation will shed light on the reasons for these failures providing both the experience and inexperienced writer of journal papers with useful advice.

Properties of multiple recycled concrete aggregate ABED, Mohammed; NEMES Rita Budapest University of Technology and Economics

Keywords: Los Angeles test, recycled concrete aggregate (RCA), Multiple-RCA, water absorption The mechanical and physical properties of the coarse recycled concrete aggregate (RCA) and multiple recycle concrete aggregate (Multiple-RCA) have been studied, where the aggregate produced from recycled aggregate concrete is not discussed in the literature despite it could be a choice in such circumstances especially in the end of the structures which already constructed by recycled aggregate concrete (RAC). More than twenty-one types of self-compacting high strength concrete have been made by natural aggregate (NCA) and RCA be crushed and their properties have been studied. The main findings of the present study that, the abrasion resistance of Multiple-RCA decreases by increasing the RCA dosage in its parent concrete up to 50%, however, the cement replacing materials (CRM) in parent concrete help to enhance the abrasion resistance of RCA and Multiple-RCA and change its absorption capacity. A strong relationship between the absorption capacity of Multiple-RCA and its parent concrete has been observed but no direct relationship is investigated in case of the strength, where in case of high strength concrete the strength can depend highly on the mortar strength rather than the aggregate type.

Implementing quantitative techniques to improve decision making in construction projects: a case study ABUSALEM, Osama; BERTALAN Nikolett; KOCSI Balázs University of Debrecen

Keywords: quantitative techniques, time- and cost-oriented FMEA, Monte Carlo Simulation Decision making is the process of choosing between alternatives to achieve a goal. Despite the tremendous development of scientific management and the widespread applications of several quantitative techniques in decision making, the deterministic approach still dominating the decision making in numerous construction companies rather than the stochastic approach. This may result in severe ramifications in achieving the predetermined project objectives of time, cost, and quality and it may go beyond that to the bankruptcy. This research serves to fill a gap in the body of knowledge pertaining to replacing the deterministic conception of decision making in the construction industry by the stochastic conception through evaluating the effectiveness of implementing scientific management to improve decision making in construction projects by using quantitative techniques, including time- and cost-oriented Failure Mode and Effect Analysis (FMEA) and Monte Carlo Simulation (MCS). The scope of this research is limited to project schedule and risk management of one phase of a construction project to build a new automated warehouse of a manufacturing company in Hungary. The results show that the deterministic approach is ineffective in delivering the construction projects because it represents systems that do not contain any probabilistic (random) components, where all mathematical and logical relationships between elements (variables) are fixed in advance and not subjected to uncertainty. The probability of finishing the construction project based on the deterministic model is 50%, while the probability of finishing the construction project based on the stochastic model is 20%; there is a drop of 30% between the two models. Accordingly, it should be replaced by the stochastic approach that take into consideration the potential impact of project risks and other sources of uncertainty on achieving project objectives.

Thermal performance evaluation of the Algerian vernacular houses in the region of the Ziban-Biskra: hot and dry climate ADEL, Boumerzoug1 ; MESSAOUDA, Rais2 ; LEILA, Sriti1 1 2

University Mohamed Khider Biskra University of Pécs

Keywords: vernacular houses, thermal performance, hot dry climate, Ziban, Biskra, Vi-suite Contemporary Building in Algeria consumes a large amount of the overall energy consumption used, due to its design which does not address the local climate conditions. Contrary to this, vernacular architecture is widely acknowledged that it is a genuine climate-responsive and environmentally-friendly architecture. This study is focused on evaluating the thermal performance of the Algerian vernacular houses in the hot and dry climate in the region of the Zibans, Biskra. It was conducted by choosing two different houses in this region and using dynamic simulation with Vi-Suite add-on for Blender 3D software. Moreover to validate the results a field measurement was conducted during three-days in different hours.

Keywords: glycemic control, critical care, blood-glucose dynamics, stochastic noise, stochastic differential equation, Intensive Control Insulin-Nutrition-Glucose (ICING) model, Stochastic Targeted Control (STAR) The model of the human glucose-insulin system plays an important role in several clinical treatment methods and protocols, like tight glycemic control of intensive care patients. The Intensive Control Insulin-Nutrition-Glucose (ICING) model is one of these protocols that was used for the development of Stochastic Targeted (STAR) glucose control protocol that is used as a standard of care in hospitals in New Zealand and Hungary. The original ICING model uses ordinary differential equations (ODE) for the description of the glucose-insulin system. Recent studies attempted the extension of the original ICING model with stochastic terms. By using the resulted stochastic differential equations (SDEs) we may have the chance to improve the accuracy of modeling. In previous studies the stochastic version of the ICING model (ICING_SDE), was tested and compared with the original version of the model (ICING_ODE) using a limited number of randomly selected patients, and focusing on the comparison of the insulin sensitivity (SI) prediction of the two models. In the study presented in this paper we went further in this comparison with a larger clinical data set including treatment records of 60 patients. This validation data set includes representative set patients from 3 different geographically distinct cohorts, from Belgium, Hungary and New Zealand. This analysis included patient with wide range of blood glucose consecration (BG) and treatment time period. The current comparison is focused at the BG values and the modeling error. First we used both models to identify the SI profile for every patient, then we used the identified SI profiles to simulate the BG values with the same nutrition and insulin input functions that was used during the treatment. Based on the simulated outputs (BGs) and the real BG measurements (see Figure 4.1) we calculated and compared the absolute and relative error in every minute for both models (ICING_SDE and ICING_ODE). We used also different statistic aspects like the Mean and IQR. The results show that the SDE model was more accurate and the ICING_SDE modeling error was smaller than the ICING_ODE model in 95% of the patients with an average rate of 64% better estimation up to 87% for all the given measurement point. These results suggest that SDE model may be used to improve the BG prediction process and the estimation of the blood glucose level of the patients in the future and that is an important step of the STAR protocol. Thus these results may lead us to better clinical treatment.

Historic masonry diagnosis: reliability of single and combined minor- and non-destructive techniques BALLA Brigitta Department of Civil Engineering, PTE-MIK

Keywords: cultural heritage building, masonry wall, mortar, rebound hammer, moisture meter, SEM Historic masonry diagnoses is an important part of building analysis and consistency survey procedures. The interpretation of masonry analysis results of historical buildings made out of brick and stone is considered more subjective than of concrete structures. Therefore the improvement of the used techniques and finding better correlations between the results and the mechanical properties proves to be of great importance. Several diagnostic procedures are commonly used in practice, such as rebound hammer test, drilled sample analysis etc. Results of these methods are relatively exact, their variability is low, however, several factors affect the obtained results, which have to be taken into account. Humidity shows the condition of the structures and helps to specify the results of the other diagnostic procedures. This presentation focuses on the study of the practical use of several minor- and nondestructive methods. The presented case study relates the examinations conducted by using pendulum hammer, moisture meter device, SEM (scanning electron microscopy), etc. The use of two or more methods at the same time for the same diagnose procedure – the so called combined techniques method - is indispensable in order to obtain reliable results.

Experience of construction: comparing studio and practical education BORBÉLY Fruzsina Anna Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs

Keywords: education, workshop, wood The Faculty of Engineering and Information Technology, University of Pécs has attended four architecture camps, organised by the HELLO WOOD company. This paper is a brief summary about the four wood installations, and a comparative study of the general architecture classes and the architectural BUILDER camps. Usually students design a project in a semester, and than start another one, without any feedback if the designed building, structure or material etc. is working in real. In this builder camp, student can follow and have part of the full process from the very beginning, through the design to the constructed installation. Building by two hands, or twenty in a team, can teach you how to solve the sudden problems during construction, have knowledge about materials and tools, and have experience how structures works. The University of Pécs has already implemented four project. In the first two years the location was Csopak and the main topic was about temporary architecture. In the second two years the chosen area was Tokaj, which include 27 village, . In these cases the projects were mostly constant. Both of them were unique and exciting architecture exercise, where the participants could learn and evolve. The study will describe all the advantages of a builder camp, comparing with the general architecture studies, by presented the four existing projects.

Optimisation of the SCS-CN initial abstraction ratio in a catchment prone to flash floods. Case study of the Husí potok catchment, Czech Republic CALETKA, Martin; MICHALKOVÁ, Monika Šulc Department of Geography, Faculty of Science, Masaryk University, Brno

Keywords: flash flood, critical points, initial abstraction ratio, SCS-CN, surface runoff The SCS-CN method is a globally used popular approach to simulations of surface runoff. Its advantages reside in low demand on the input data and relatively simple application and computation. Nevertheless, the correct simulations require proper setting of the model’s components. This work focuses on optimisation of initial abstraction ratio Ia/S in the Husí potok catchment, the Czech Republic, and its sub-catchments using pairs of discharge and precipitation measurements in period 2008-2016. Due to favourable morphology, the catchment is prone to flash floods. Major flash floods, which occurred in 2009 and 2010, caused severe damages. The attention of this research is focused on the evaluation of various aspects to assess the potential of surface runoff generation using the so called Critical Points method (CP). In parallel, the influence of the antecedent precipitation on the SCS-CN variables towards good representation of surface runoff has been analysed. The results outline that in this particular catchment, the Ia/S ratio is generally lower than the default one (Ia/S = 0.20). Thus, the SCSCN method requires certain modifications according to the local specificities in the watershed. The findings obtained in this research will serve as a useful contribution to proper calibration in surface runoff modelling.

Pavement layer element modeling based on mechanistic-empirical design method for an international practice CHO, Seoyoung; TÓTH Csaba Budapest University of Technology and Economics

Keywords: pavement response; finite element method (FEM); mechanistic-empirical design method (MEPDG); climatic factor; pavement layer The pavement design paradigm is changing in the way to take into account mechanistic concept for more realistic analysis. This mechanistic-empirical pavement design guide (MEPDG) can deal with multiple mechanistic variables at the same time, thus it has been used in complex problems such as verification of environmental effect on pavement structure. In this numerical study, the whole pavement structure will be modeled as a layer element so that the verification of effect of each layer on the whole pavement structure’s response upon seasonal variation be possible. By employing finite element method (FEM) each and every effect and response can be measured. Two different design codes will be used for the comparison; Korean method and Hungarian method. The aim of this study is to figure out how the climatic factor effects on the whole pavement structure when the layers are modeled according to MEPDG.

Combined sewer network assessment in the implementation of the rainwater runoff reduction objects CSICSAIOVÁ, Réka; STANKO, Štefan; MARKO, Ivana Slovak University of Technology in Bratislava, Faculty of Civil Engineering, Department of Sanitary and Environmental Engineering

Keywords: rainwater; sewerage network; rainfall-runoff process The contribution is aimed at finding out the behavior of the combined sewer network in the event of the occurrence of extreme precipitation events, which are associated with changes in the rainfall - runoff process in the urbanized area. The urbanized part of the town of Vráble, located in southern Slovakia, was chosen to solve the problem. Project documentation of sewerage network were provided by organization Western Slovak Water Company (ZsVs a.s.), which is the operator of the sewerage network in the town of Vráble. A thorough analysis of the background revealed the need for a visual overview of the area being solved. During the project documentation analysis were detected several defects and inaccuracies, which required visual inspection of the identified locations. There were missing data on the connections of individual sewers and data on the correct position of shafts. Measurements were taken to complete the individual input data. Given the current situation of increased surface runoff in the urbanized area, it is necessary to extend the use of objects to reduce rainfall to the sewerage network. Part of the contribution was the design of infiltration objects, which are among the most used and most effective reduction measures. The impact of the reduction measures was also considered when assessing the impact of rainwater on overflow of the sewerage network using block rains with selected periodicities (p = 0.2 p = 0.5 and p = 0.05). The result is the mathematical model of the combined sewer network before the implementation of the reduction measures and the model of the sewerage network with reduction measures. After designing the infiltration equipment and reducing the amount of rainwater discharged into the single sewerage network, the assessment of the sewerage network is satisfactory throughout the whole territory.

Hydrological-hydraulic assessment of existing flood protection measures ČUBANOVÁ, Lea; ŠOLTÉSZ, Andrej; JANÍK, Adam Department of Hydraulic Engineering, Faculty of Civil Engineering, Slovak University of Technology in Bratislava

Keywords: assessment, flash flood, flood protection measures, hydraulic design Presently, implemented flood protection measures come to a re-evaluation due to changes in the hydrological situation, especially due to more recently occurring flash floods whose intensity exceeds the capacity of the measures initially proposed. The problem are the structures constructed on the streams as well as the unpermitted house building on the banks, the pollution of the stream or its sedimentation. Newly-designed measures are not acceptable by ecologists, have problem with property-legal relations (especially with unsettled lands that could serve as places where water from the stream could overflow without life and property endangering or where the detention reservoir could be realized) and lack of funding for radical solution of such situations. The contribution presents a hydrological-hydraulic assessment of the flood protection of the village in middle part of Slovakia. During the common hydrological situations the stream flows at minimum water level (few centimetres). However, the design flood wave has a huge volume. The river bed training is not possible, not even its widening or ensuring by dikes, so it seems the most appropriate solution to design detention reservoir above the village with such a runoff that the river bed is able to transfer it without overflowing in the village.

Analysis of the collision of a ship with a dolphin CZAJKOWSKI, Jakub; SASUŁA, Michał Wrocław University of Science and Technology

Keywords: dolphins, energy method, nonlinear material, bilinear contact, Newmark method Paper Dolphins are marine and inland structures that extends above the water level and are not connected to shore. They can have many uses. Most often they are utilized to provide protection for important structures (bridges etc.) from possible impact by ships. They provide the similar function as the road barriers. In the paper results of a simple analysis of the ship’s collision with a dolphin are presented. A simple energy analysis of the collision was performed. The relationship between the force and the dolphin deformation was derived. In the paper numerical calculations were also carried out. The calculations took into account the non-linearity of the material, the von-Mises yield criterion was considered. Bilinear model was used to model the ground. Due to the dynamic characteristics of the collision, the Newmark method was implemented. Obtained results can be helpful in further designing process of the dolphin structures.

Landscape design method of urban waterfront slow-motility space, taking the landscape design of Riverside Road in Changxing as an example DAN, Ge1 ; BACHMANN Bálint1 ; GYERGYÁK János2 1

Marcel Breuer Doctorate School, Faculty of Engineering and Information Technology, University of Pécs 2 Department of Architecture and Urban Planning

Keywords: waterfront, slow-motility space, functional organization, visual organization, spatial sequence Under the background of the redevelopment of the waterfront and the transformation of living attitude and transportation modes, the waterfront area has become an important destination for people to carry out recreational activities. The recreational activities include strolling, running, cycling, fitness, viewing, communication and so on. The rich functional activity space creates the vitality of the waterfront space and is also a prerequisite for the recreation activities. The slow-motility space is the place for walking, running and cycling. Besides the traffic functions, it is also a dynamic landscape space that connects different functional activity venues, and the main way that people perceive the waterfront landscape. Therefore, it is the most important part of the landscape design of the waterfront. The waterfront area has many different types according to scales, function of the surrounding environment, and the relationship between water and city. But as a place for recreational activities, the linear waterfront area has common spatial characteristics, such as reachability, continuity and possibility of staying. These three attributes are also the principles and goals of slow-motility space landscape design. Taking the Landscape Design of Riverside Road in Changxing and other projects as examples, the landscape design method of the waterfront slow-motility space was analyzed from three aspects: functional organization, dynamic views organization, and spatial sequence perception.

Homelessness in the beginning of 21st century in Pécs and Denver DANYI Tibor Zoltán PTE MIK

Keywords: social housing, homelessness Despite all efforts one of the biggest challenges for both Hungarian and American society is the homelessness. My research was conducted in parallel in Pécs and Denver. I have tried to find out what similarities and differences exist in dealing with the situation of homeless people in these countries which differ significantly from each other in many ways. A questionnaire survey, conducted with hundreds of homeless, can help architects understand the circumstances of homelessness. The ongoing survey by interviewing hundreds homeless can help us architects to understand the conditions of homelessness, as well as finding and designing architectural suggestions, which offer an appropriate and acceptable solution at the beginning of 21st century, to the many members of this diverse social layer.

A contribution to BIM education in Serbia - the case of the Faculty of Architecture, Belgrade DEVETAKOVIĆ, Mirjana; RADOJEVIĆ, Milan University of Belgrade, Faculty of Architecture

Keywords: BIM, education, industry, university, cooperation Integration of BIM (Building Information Modelling) in existing architecture curriculum is challenging academia worldwide. It is for many reasons, such as multidisciplinarity, practice and business orientation, high explicitness in representation, huge hardware demands, and sensitive availability of real life examples, just to name few. In this study we present and examine the results achieved in introduction of BIM related contents in education of architects in Serbia, with particular attention on actual courses at the University of Belgrade, Faculty of Architecture. After defining the scope of BIM in general and highlighting the issues in focus of the international BIM community, the basic elements of BIM that need to be introduced in various stages of architectural education have been reviewed. Particular attention has been paid on multi-dimensionality of BIM application in life cycle of buildings, i.e. the areas of 3D (modeling, clash detection, scheduling, quantities), 4D (chronological monitoring of the building processes), 5D (financial management) and 6D (facility management). Presenting the results achieved in education so far, we stress the importance of cooperation with industry, and analyze the case of educational/practice partnership between Lafarge Housing Serbia Group and the University, established in scholar year 2017/18, as well as the educational partnership with Serbian BIM development company BEXEL Consulting. Finally we discuss the actual BIM scene in Serbia and the region, and propose a range of educational activities that might lead to increasing competitiveness of our BIM professionals on the global AEC market.

Impact assessment of the planned closure structure on ground water level regime DINGETU, Shenga Zinaw; DANA, Baroková; ANDREJ, Šoltész Department of Hydraulic Engineering, Faculty of Civil Engineering, Slovak University of Technology in Bratislava

Keywords: closure structure, flood protection, hydraulic assessment, numerical model Increase of the flood protection of lowland regions is one of the main topics of water management boards in Slovakia. The contribution deals with description of the closure structure which should be constructed on Little Danube and its tributaries to protect the territory against the backwater during the flood on Váh and Danube rivers as well as with hydraulic assessment of impact of proposed technical measures on ground water level regime in adjacent region. The problem is all the more substantial because the damaged region belongs to network of nature protection areas Natura 2000 and the review of surface and subsurface water levels is of highest importance. Based on available hydrological, geological and hydrogeological data numerous simulations were carried out for both - steady state and transient flow conditions.

Keywords: Thermal performance, Household sector, Building Simulation, IDA ICE 4.7.1 In Egypt, the energy consumption increases due to the growing population. Moreover, the energy demand in Egypt has increased by 7.5% per year, housing construction rate is not enough to face the population growth, therefore the Egyptian government started to solve the housing problem by constructing 13 new urban communities. New Minia is one of the new cities that have been established in Upper Egypt. This study is focused on analyzing four types of residential buildings in New Minia city (Upper Egypt). This analysis is aimed to assess the energy performance and thermal comfort, using IDA ICE 4.7.1 through different energy efficiency measures. The results show that the energy consumption and thermal analysis are mostly affected by the construction techniques, orientation and materials.

An application to solve nonlinear constrained multi-period production problems ERCSEY Zsolt1 ; NOVÁK Péter1 ; KOVÁCS Zoltán2 1

Department of System and Software Technology, Faculty of Engineering and Information Technology, University of Pécs 2 Department of Computational Optimization, Institute of Informatics, University of Szeged

Keywords: multi-period production, nonlinear, constrained, parametric study Cost considerations are key issues that influences the profitability of a business. Finding the optimally balanced costs in a production environment is a crucial task in practice; however, it is not a trivial problem. Situations are even harder to solve when a multi-period production environment is considered, where conditions vary among the periods. Based upon the WagnerWithin property, several approaches emerged to solve multi-period production problems with linear cost models where both production and inventory are unbounded. Recent solutions took account of constraints on these parameters, still, with linear costs only. Other investigations deal with error correction methods when exact information is missing or not available when the calculations occur. The present work focuses on the development of an application in C# that effectively solves industrial problems where both production and inventory levels have bounds and their corresponding cost functions are more general, i.e. are nonnegative, monotone, concave functions. Through parametric studies performed with this application, it is illustrated that the constraints do not effect the optimality criterion but the feasibility of the production problem.

Analysis of short-term rainfall future changes using climate change scenarios in the North-Western part of Slovakia FÖLDES, Gabriel; KOHNOVÁ, Silvia; LABAT, Marija Mihaela Department of Land and Water Resources Management, Faculty of Civil Engineering, Slovak University of Technology, Slovakia

Keywords: short-term rainfall, trend analysis, scaling, design values, RCM scenarios The paper focuses on the analysis of the future changes in short-term rainfall characteristics using outputs from various Regional Climate Models (RCMs) scenarios. Analysis was done for 4 climatological stations in the North part of the Western Slovakia in the region of Myjava. The region is classified into a slightly warm climatic zone with a mountain temperature with an average annual air temperature of 8.7 °C and an average rainfall of 600 to 700 mm. Data used for analysis were used from real observations and from regional climatological scenarios. The real observation period was from 1995-2009 and for the future scenarios outputs were available for a period from 2060-2100. The analysis focuses on the future changes in seasonality, trends and changes in the scaling exponents, using methods e.g. Mann-Kendall trend test, Burn´s vector for seasonality changes and simple scaling for changes in the scaling exponents. The paper assumes changes that can be expected for the future in the short-term rainfall in the region and changes in the values of design rainfall that have impact on a future engineering studies.

Comparative analysis for traditional yurts using thermal dynamic simulations in mongolian climate GANTUMUR, Tsovoodavaa; KISTELEGDI István Szentágothai Research Centre, MIK

Keywords: vernacular architecture, nomadic country, Mongolian climate, climate zone The yurt is one of the ancient living units for the nomadic cultural country. The yurt is a nomadic vernacular architecture which developed during the 3000 years. There are 31 counties using the yurt, out of which 13 of them use its traditional yurt around the world. Basically, yurts used as residential housings and also to some extent, for commercial and touristic purposes under different climates. Analyzing existing professional literature, as well as scientific publications it is apparent that besides architectural and structural topics there is no existing investigation or published paper about building physics analysis of these buildings. Current research aims to create a database about the energy and climate comfort qualities of traditional yurts using dynamic calculation tools. As a result, we intend to learn from the traditional yurt technology and we plan to develop a completely new and modern building based on the yurt-experiments in further future research. Firstly, finding optimal solutions for a contemporary “yurt-building” should be applied under Mongolian climate conditions, since this form of housing is still used in this country, and, in addition, the comfort and energy performance of the yurts were surprisingly satisfactory under extreme weather conditions, by temperature differences between summer and winter of approximately 80 K.

Kinematic based structural optimization of robots GHAFIL, Hazim Nasir1,2 ; JÁRMAI Károly2 1 2

University of Kufa, Najaf, Iraq University of Miskolc

Keywords: optimization, structural optimization, Harmony search algorithm, simulated annealing, robotics, dimensional synthesis The next important step in the Kinematic synthesis of a robot arm is the dimensional synthesis where the dimensions of the type have to be calculated. In this paper, a detailed method was presented to estimate the optimal dimensionality using heuristic and metaheuristic optimization algorithms. Simulated annealing and harmony search algorithm were proposed as heuristics while artificial bee colony was introduced as metaheuristic for this purpose. The presented method was applied to optimize the structure of a 6 degree of freedom DOF industrial KUKA robot as well as a new design of a 7DOF robot arm mimics the functionality of SANDVIK robot manipulator which is used for tunneling works. The type synthesis of the 7DOF was designed on the basis of graph theory, and it solves some restrictions on SANDVIK robot. Simulation software was built in MATLAB also has presented in work to represent the optimized structure of the 7DOF robot arm. To ensure the validation of the results, the 7 DOF robot with its optimized dimensions is simulated in a 3D package, which is 3DS Max, with real environment dimensions as shown in Figure 25.1.

Optimal stress-strain analysis of a robot arm through finite-element and simulated annealing algorithm GHAFIL, Hazim Nasir1,2 ; JÁRMAI Károly2 1 2

University of Kufa, Najaf, Iraq University of Miskolc

Keywords: finite element analysis, simulated annealing, robotics, design, optimization For a heavy duty, induced stresses and deflections in a robot arm should be investigated to be in the allowable limits to avoid the state of the failure. One of the popular methods to investigate the stress is the finite element analysis FEA which depends on a set of a given boundary conditions. This work presents a generalized method to calculate the optimum boundary conditions for a robot to be analyzed by FEA. The proposed optimizer is the simulated annealing algorithm, and ANSYS is proposed as a finite element package through this work. The proposed method and analysis are introduced in detail through a three degree of freedom robot manipulator, and all results are simulated and discussed. In this work, simulated annealing algorithm has optimized a trajectory equation for each joints of the robot, and these developed optimum equations are used as joint loads in transient structural analysis as shown in Figure 26.1. The present calculations introduced implicit way to check the angular acceleration limits of the actuators of the robot arm if it is within the allowable range or not.

Improvement methods of internal combustion engine efficiency GUELLOUH, Noureddine; SZAMOSI Zoltán; SIMENFALVI Zoltán Institute of Energy Engineering and Chemical Machinery, University of Miskolc

Keywords: internal combustion engine, improvement, efficiency, method Increasing efficiency is a key issue nowadays in combustion technology. Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. Thermal engines can be classified into two categories, internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and external combustion engines (steam piston, steam turbine, and the Stirling cycle engine). In case of internal combustion engine (ICE), there are many factors that limit efficiency such as heat losses in exhaust gases, losses due to incomplete and imperfect combustion, heat losses during cooling of engine, imperfect valve timing, etc. This led to increased interest in this topic, where a lot of research is being done to find solutions and to achieve a significant development in the value of efficiency. In this paper, a comprehensive review of improvement methods of internal combustion engine efficiency is represented, among them variable injection timing, using of turbochargers, direct fuel injection, regenerative braking, variable valve timing, etc.

Post conflict reconstructions in Bosnia and Herzegovina HADŽIĆ, Damir Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology

Keywords: reconstruction, post-conflict, destroyed, cultural heritage properties, restoration, process of restoration To reconstruct or not to reconstruct is now the question... to post conflict Bosnia and Herzegovina this was not the question, or maybe it is better to say for post Dayton peace agreement in Bosnia and Herzegovina (14 December, 1995). How strong agreement for peace can be? Well it stopped the long conflict and arranged many things such as return of refugees and reconstruction of destroyed cultural heritage. Was this the end or just the beginning? Maybe now, after the years, it is the proper time to say. In a way it helped to resolve a lot of starting questions, and surely helped to safe rest of many destructed monuments and to safeguard them to be restored in proper manner, even there were attempts not to do so. Large number of properties were considered impossible to restore and way too difficult we can say now that reconstructing the heritage in B&H was a task that is still not finished, there are numbers of monuments that are still waiting to be reconstructed or they are in the way to be reconstructed. How to justify these reconstructions in Bosnia and Herzegovina is not difficult, by its placement in Dayton peace agreement it is clear that annex 8 is considered as part of human right of people to its heritage, coming just after annex 7 that is based on return of refugees to their homes after exile. Main aim of the research is to discuss questions about post conflict reconstruction of cultural heritage properties and involvement of peace agreement into a return of refugees and reconstruction of their destroyed cultural heritage. This can be reviewed by examples of reconstruction on significant monuments like Mostar old bridge (UNESCO site), Ferhat pasha mosque in Banja Luka, Handanija mosque in Prusac, Kujundžiluk bazaars in Mostar, Orthodox Monastery in Zavala and Land museum in Sarajevo. Investigation is focused by the results of survey on assessment of the impact of Swedish organization Cultural Heritage without Borders engagements in Bosnia and Herzegovina in post conflict time. A reflection of economic situation in Bosnia and Herzegovina is more evident in the study, than on other hand their attitude towards cultural heritage or importance of its reconstruction.

Parameter identification of a heavy-duty truck suspension for vibration analysis HAJDU Flóra; SZALAI Péter; KUTI Rajmund Department of Mechatronics and Machine Design, Faculty of Mechanical Engineering, Informatics and Electrical Engineering, Széchenyi István University

Keywords: parameter identification, fire truck, system modeling, vibration For efficient, economical operation of vehicles, it is essential to examine various vibrations during operation. Particularly measurements that have been performed in field experiments in real operational conditions provide forward-looking results. These measurements can greatly support vehicle development, especially in case of vehicles with special needs, such as fire trucks. Therefore a CSD-755-10 heavy-duty fire truck was chosen for our study. In our previous research the chaotic vibrations during operation were examined in simulation environment using the half-vehicle model. In this research the parameters of the fire truck front suspension are identified, for which the quarter car model is used. In this presentation we briefly describe the theoretical background of parameter estimation and the methods to be used, and then outline the parameter identification of our system and show the results of our measurements. With our research we want to draw the attention to the importance of the topic and to help the safe operation of fire-fighting vehicles.

Towards dynamic SLA algorithms in Cloud Computing HALILI, Merita Kasa; ÇIÇO, Betim South East European University

Keywords: SLA, Cloud Computing, Dynamic Algorithms In Cloud Computing, Service Level Agreement (SLA) is a contract that defines a level and a type of QoS between a cloud provider and a client. In recent years, cloud computing has become an increasingly important software delivery paradigm, mainly for reasons of increased scalability. The scalability benefits are accomplished by the capability of autonomously and elastically scaling up or down so that customer preferences (SLAs) can be accommodated. In this paper we discuss about self adaptive SLA algorithms. Our aim is to review different research papers that have realized different algorithms that automatically adapt to requests or changes made by users. We discuss the advantages and limitations of current algorithms with the help of diagrams. Then we propose our possible future work and at the end we summarize and provide conclusion.

Designing new buildings into historical areas – Ceramics manufacture and showroom HENDRIX, Thimea Catharina Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology

Keywords: historical, monumental area, ceramics, manufacture, architectural heritage Designing new buildings into historical- and monumental areas can be challenging. The principles of integrating new edifices into continuous building lines apply here; while the flawless connection of the existing- and the recently planned structures is also essential. The new building should respond to its surroundings, yet it has to be distinct – as they are the products of different architectural eras. The planning site of the ceramics manufacture and showroom is located in Ferencesek street, Pécs. The core attribute of the street is that it has 22 listed historical buildings; most of them were designed – or at least refurbished - in classicist style, while the street also has eclecticist, romanticist and baroque styled facades. Through the planning process one of the main difficulties was to react to the surrounding facades, as they are well embellished – embossments, screening, etc. It was also challenging to handle the gables correctly and deal with the attributes of the site. One of the main conceptual principles was to redefine the structure of the surrounding facades and to create a structure with contemporary methods, that fits into the view of the street and also meets the functional requirements. It was a conceptual priority to handle the gables correctly, to reconsider the usage of small patios – as they are common in Pécs -, also to guide the visitor through different functions and create green areas that are absent from the street. The goal was to design a new building into the street that represents the architectural principles of Pécs.

Preserving the historical centers in Algeria: the evaluation of the modern challenges in the Casbah of Algiers HIBA Barbara; MOLNÁR Tamás University of Pécs, Faculty of Engineering and Information Technology

Keywords: the historical center of the Casbah, world heritage, colonial heritage, preservation The historic center of the Casbah of Algiers is one of the most remarkable Medina of the Maghreb, enclosed with the ex-French military quarter; the composition of this antithetic urban fabric represents a summary to the history of Algeria, framing a unique intersection of identities, that raises the questions to heritage preservation of the country today, in the light of modern developments and urbanization. Holding the title of the UNESCO World heritage; the preserved sector of the Casbah, is demanding a continuous solid planning of conservation and control, that needs to be equally extended to other regions in Algeria, with similar historical; architectural and urban complexities. Based on the analyses and the evaluation of the typo-morphological state of the art of various historical colonial and indigenous centers in Algeria; using different comparative methods, the research aims to present a new interpretation and methodology to the preservation and planning of the Franco-Algerian historical centers and monuments, by merging the urban and architectural formal applications with the social perspective in order to determine the effect of the collective memory on the perception of the historical space and the acts of heritage protection and conservation.

The sensitivity analyses of soil parameters and their impact on runoff-erosion processes: the application of erosion 3d model in small Slovak catchment HONEK, David1 ; NÉMETOVÁ, Zuzana2 ; KOHNOVÁ, Silvia2 ; MICHALKOVÁ, Monika Šulc1 1

Keywords: soil parameters, sensitivity analysis, EROSION 3D, erosion and runoff processes The modelling of soil erosion processes is affected by several factors reflecting the physicalgeographic conditions of the study site together with the social-economic linkage. The resulting soil parameters are significant in the modelling of erosion and also runoff processes. That’s why the correct determination of soil’s parameters becomes a crucial part of the research. These soil parameters are necessarily as the input data set for any modelling approach. This paper deals with the sensitivity analysis of the soil input data to physically-based EROSION 3D model. The sensitivity analysis of the model was performed for the following parameters: bulk density, skin factor, initial moisture, roughness, erosion resistance, vegetation cover and organic matter content. The aim of the analyses is to determine the influence of input soil parameters on the runoff-erosion processes. The EROSION 3D model was applied in the Svacenicky creek catchment (6.3 km2) in the middle of the Myjava Hill Land in Slovakia. The results show the variable influence of each soil parameter. The EROSION 3D model is very sensitive to initial moisture, bulk density and skin factor. Lower affect is caused by organic matter content, and some of the soil parameters had “no influence” on the particular modelled values, respectively runoff-erosion processes. The diversity of the results pointed to complexity of the EROSION 3D model and the complicated assessment of runoff-erosion processes. The strong relationship between the “input” soil parameters and “output” modelled values was also confirmed, which outlines the necessity of correct determination of all input parameters.

Segmentation of cylinders from point clouds HONTI, Richard Department of Surveying, Faculty of Civil Engineering, Slovak University of Technology in Bratislava, Slovak Republic

Keywords: point cloud, cylinder extraction, automated data processing, cylinder fitting The advantage of terrestrial laser scanning (TLS) over conventional surveying methods is the efficiency of spatial data acquisition. With current scanners, very large sets of 3D points of required accuracy can be collected easily and quickly. The results of scanning are point clouds, which are becoming an increasingly common initial digital representation of realworld objects. Since point clouds in most cases represents a huge amount of data, automation of the processing steps is advisable. In this paper an innovative algorithm is proposed for automatic detection of cylinders and estimating their parameters from 3D point cloud data. First, the normal vectors are computed for each data point as a preprocessing step. Then a cylindrical surface is extracted from the neighboring points of a randomly chosen seed point. The fitting process is applied iteratively to update the inlier points to the extracted cylinder (i.e. the remaining points of the point cloud are tested, if they belong to the cylinder surface). Finally, the parameters of the cylinder are estimated accurately. This procedure is applied iteratively to extract all the cylinders from the point cloud. The proposed algorithm was implemented to a standalone application based on MATLAB® software. The method was tested on complex point clouds with different levels of noise and outliers. The paper also brings a short review of most reliable methods of cylinder extraction.

Active House certification of the first Hungarian Active House under consideration of comfort, energy and environmental criteria system HORVÁTH Kristóf1 ; KISTELEGDI István2 1

Keywords: residential building refurbishment, Active House certification, thermal comfort, operative temperature, CO2-concentration, daylight factor, final energy demand, energy supply, primary energy consumption, environmental loads, freshwater, sustainable construction, thermal building simulations, national energy calculation method, LCA The first Hungarian Active House refurbishment was built in Pécs, designed by Professor Dr. István Kistelegdi. The project won the international Active House Award 2017 and the shortly later the Energy Globe Hungary 2017 prize. The family house combines energy efficiency with specific attention to user health and comfort, indoor climate and the environment. The first award contained the Active House (AH) certification of the building. The purpose of this research is to evaluate the effects of the refurbishment with the help of the AH certification system. Particular paper introduces the certification results in form of so called AH radar diagrams. Two AH radar was created, one for the refurbished building and one for the former, old state. The radars are containing three major aspects of evaluation criteria, such as energy, comfort and environment, which represents a unique approach among international green building certification systems. Besides national standard building energy calculations, dynamic thermal simulations and LCA (life cycle assessment) calculations were required in the qualification process. The results delivered excellent values in energy and environment (LCA), as well as in thermal comfort and indoor air quality criteria. Visual comfort performed at a good level. Future goal is to create a radar evaluation, based on real in situ monitoring measurements in the Hungarian AH for comparison with the calculation based ‘theoretical’ radar. After calibration the simulation based radar, a validated, useful tool can be developed to support the design of healthier and more comfortable buildings with highest level of energy efficiency and lowest LCA-impact.

Experimental research of corrosion effects on steel bridges JANČULA, Miroslav1 ; VIČAN, Josef1 ; SPIEWAK, Anna2 1 2

University of Žilina, Faculty of Civil Engineering, Department of Structures and Bridges Faculty of Civil Engineering, Czestochowa University of Technology

Keywords: corrosion, steel bridge, durability Bridges are significant elements of the transport infrastructure, so they should be in operation throughout the whole design life. Therefore, it is necessary to know the main causes of damages and failures of the bridges. The corrosion of structural steel caused by atmospheric influences as well as the bridge exploitation cause a cross-sectional reduction of structural elements and, consequently, a decrease of the resistance of steel bridge members. The article deals with corrosion and its impact on steel bridge elements in order to use this data for developing actual corrosion model appropriate for design of structures on durability.

Hydraulic analysis of the flood protection in Bardejov, Slovakia JANÍK, Adam; ŠOLTÉSZ, Andrej; ČUBANOVÁ, Lea Department of Hydraulic Engineering, Faculty of Civil Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovakia

Keywords: flood protection, hydraulic assessment, flood protection measures, mathematical modeling, flood Floods are one of the most destructive - and most common – natural phenomenon all around the world which cause massive economical losses and, in less fortunate cases, can cause also casualties. People fight with this phenomenon since they started to build dwellings in tight proximity of rivers or streams. It appears that this fight will continue in the future more intensively because climate change seems to be making these catastrophic events even more extreme. The contribution is dedicated to hydraulic analysis of the flood protection of county town Bardejov in the north-east part of Slovakia where, after numerous floods on the Topl’a River, the flood protection has been constructed just partially (phase I.) Next phases II. and III., which append to phase I. upstream and downstream, are currently in a process of evaluation, so the flood protection of town is far from being complete. The submitted article deals with hydraulic assessment of realized flood protection measures and their impact on proposal of phases II. and III.

Compressed welded box columns optimization and comparison JÁRMAI Károly; PETRIK Máté University of Miskolc

Keywords: welded column, structural optimization, overall stability constraint, minimum mass Stability is one of the most important problems in the design of welded metal structures, since the instability causes in many cases failure or collapse of the structures. The aim of the present study is to show the minimum mass design procedure for welded steel box columns loaded by a compression force (Fig. 41.1). The normal stresses and overall stability are calculated for pinned columns. The dimensions of the box columns are optimized by using constraints on overall stability, local buckling of webs and flanges. The different design rules and standards, like Eurocode 3, Japan Railroad Association (JRA), American Petroleum Institute (API), and American Institute of Steel Construction (AISC) have been compared. The calculations are made for different loadings, column length and steel grades. The yield stress varies between 235 and 690 MPa. The optimization is made using the Generalized Reduced Gradient (GRG2) method in the Excel Solver.

Shape optimization of protective covers for heat treatment JÁRMAI Károly1 ; SZŰCS Renáta2 1 2

University of Miskolc S&G Solution Ltd.

Keywords: welded steel shell, heat treatment, corrugated shell A welded steel protective cover is investigated, which is used for the heat treatment of steel sheet coils. Protective covers are made of austenitic stainless steel. It consists of three main parts, welded together, which have 1400 mm height each. The plate thicknesses at the lower, middle and upper parts are different. The aim of the investigation was to improve the lifetime, the number of heat cycles of the protective cover, changing the geometry, the thicknesses and the material. We have evaluated the damaged covers, made calculations on stress and deformations and a series of finite element models have been investigated, comparing the behaviour of them. Both horizontal and vertical corrugated covers have been simulated and compared (Figure 42.1). The original geometry and the horizontal corrugated plate are identical from the stress level point of view. The vertical position of the corrugated plate gave a better result to the horizontal one. The result of the original geometry is close to the measured damage.

Investigation of railway ballast materials’ particle degradation with special laboratory test method JUHÁSZ Erika; FISCHER Szabolcs Széchenyi István Egyetem

Keywords: railway, ballast, particle degradation, particle breakage, laboratory test, ballast cleaning

Background and objectives There is a product standard (MSZ EN 13450:2003) that contains requirements for mechanic parameters of railway ballast, e.g. Los Angeles as well as Micro- Deval abrasion, according to MSZ EN 1097-2:2010 and MSZ EN 1097-2:2012 standards, respectively. These laboratory tests provide the abrasion parameters of railway ballast material in the consideration of a rotating steel drum (railway ballast material has to be put into it) using steel balls, water or without them. In real circumstances this type of stress can never occur in railway tracks, but these tests are adequate to ensure the constancy of quality of production procedure, in this way these standards and testing methods are worldwidely used to evaluate abrasion quality of rocks and other products from rocks (aggregates), e.g. in concrete, asphalt and concrete pavements, etc. There should be a more realistic laboratory testing method which isn’t adequate for only the permanency in railway ballast aggregate production but for the real particle breakage simulation, like e.g. during operation conditions.

Methods A new laboratory test procedure has been developed to be able to estimate railway ballast particle degradation using dynamic fatigue (pulsating) test. This laboratory testing method can simulate more precisely the real stress and degradation procedure of railway ballast particles. The calculation of degradation is in accordance with the methods written in international literature. The required time interval of ballast cleaning (screening) can be determined, too.

Results The authors summarize the results of international literature related to laboratory degradation tests of railway ballast, as well as real field tests in tracks. Relevant parameters, statements are described, after it has been competed, own laboratory test programme and assembly are introduced and detailed. This paper contains the results of a laboratory test series related to specific railway ballast breakage evaluation method using laboratory measurement solution. In 2018 two types of andesite railway ballast sample were tested by dynamic pulsating force with five million load cycles that simulates approximately 7.5-year-loading in reality (e.g. MÁV No. 1. railway line). Particle degradation was measured and calculated after 0.1, 0.2, 0.5, 1.0, 1.5, 3.0 and 5.0 million cycles, in this way degradation trends, as well as required time interval of ballast cleaning (screening) can be defined.

Analysis and balance of phosphorous removal from waste water at urban waste water treatment plant JURIK, Lubos; LUKAC, Peter Slovak University of Agriculture in Nitra

Keywords: phosphorus, wastewater, elimination, treatment, struvite We are dealing with the problem of phosphorus at the waste water treatment plant in NitraDolná Krškany. There are several industrial areas in Nitra where are recorded the major phosphorus producers in the sewage. Within a short time, an important multinational manufacturing company will be putted into operation, which will be a potentially the significant producer of waste waters rich in other characteristic compounds, also polyphosphates that are relatively difficult to degrade in the conventional biological WWTP process. We focus on phosphorous flow (circular, balance) of individual stages of the Nitra WWTP, especially in qualitative and quantitative indicators in the form of phosphoric phosphorus (P-PO4) and total phosphorus (Ptotal). As part of the purification biological process, sludge and gas management, phosphorus is incorporated into the activated sludge biomass either simultaneously or in the context of enhanced biological phosphorus removal, And then to the chemical precipitation by the chemical coagulants. They are the salts of aluminum or iron, which after precipitation in the sedimentation tank together with microorganisms from the biological treatment creating sediment. Of course part of phosphorus gets into receiving the purified wastewater discharged because at present it is not possible through conventional biological treatment to achieve zero phosphorus concentrations in discharged waste waters. In our work we focus also the issue of the struvite. After treatment of stabilized sludge at WWTP, the rest of sludge is drained and the removed sludge is returned to the treatment process and contains a portion of the phosphorus that has already been removed from the wastewater. In the presence of ammonia and magnesia, a portion of phosphorous varies under specific conditions to form, which in a crystalline form causes significant operational and technological problems (deposits on pipelines or pumps). The struvite is one of the main alternative solutions for phosphorus recycling from wastewater. The work will deal with chemical, biological and technical possibilities to eliminate its formation and secondly to its recycling and to obtain the appropriate form of the phosphorus for further use in other areas.

Defying robustness of ensemblist and soloist deep recurrent models for traffic flow prediction KAHLOOT, Khalid; EKLER Péter Department of Automation and Applied Informatics, Budapest University of Technology and Economics

Keywords: traffic flow prediction; Deep Neural Networks (DNNs); Restricted Boltzmann Machines (RBMs), Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), heterogeneous dataset, model robustness, ensemblist, soloist, perturbation Basing a decision on a single data model can lead to impair prediction. Although a training dataset is considered as an epitome of the out-of-sample entries, including external dataset will play a nuisance role by adding more confounding variables to the original endogenous variables. In this paper, we present a cross-exogenous multi-modelling technique for blend probabilities for predicting traffic flow. Encouraging results were achieved through stacked Deep Neural Networks (DNNs), Gated Recurrent Unit (GRU), and Long Short-Term Memory (LSTM) DNNs. An Ensemblist model combined with a multitask prediction regression layer, the latter being fully connected the three-soloist model. Traffic follow prediction models (soloist and ensemblist) are being defied for studying to what limit those models would have impair prediction rather weak fit to the data. The perturbation process is distorting the selected features. Starting be 5, 10, 50, 200, 500, 700 and 1000 features are selected and perturbated. For prediction error assertion, the mean squared error (MSE) regression loss and the mean absolute (MAE) error regression loss is evaluated on this perturbated dataset for each model. A discernible outperformance in term of prediction error and model robustness is reported for the ensemblist model over the soloist models.

Comparison of forecasting methods for freight transportation by Polish railways KAMIŃSKI, Wojciech Silesian University of Technology

Keywords: railway transport, freight transport, forecasting This article presents a comparison of two methods allowing for the creation forecasts of done transport work and transported freight mass by railway in Poland. The obtained results of expired forecasts for the analyzed data were also compared on a monthly and quarterly basis. The volume of transport data used for this analysis include the period from January 2010 to June 2018. The forecasts were carried out for the period from July 2018 to December 2020. Known methods the Holt and Winters exponential smoothing models were used for the forecasting, the use of which allowed to determine the possibilities of using the data as a monthly and quarterly basis and to compare what type of data allows for obtainment more accurate results. The purpose of the article is to assess what character of the transport data (monthly or quarterly basis) makes it possible to obtain more reliable results. The forecasts obtained as accurately as possible may be crucial for decision-makers in the field of rail transport. Knowing the exact values forecasts of done transport work and transported freight mass, railway carriers can plan the number of rolling stock (both locomotives and wagons) needed to execute orders.

Diversified expressions of architectural forms Searching the laws of space composition and growth from the river network KANG, Xue Faculty of Engineering and Information Technology, Breuer Marcel Doctoral School, University of Pécs

Keywords: architectural form, secrets of natural growth; branch, transformation The development of structure science makes modern architecture show the high unity of internal structure and external contour. The form of architecture reflects the spatial variables of this complex composition. As we all know, we live in what a complex and magical system of nature. The constitution of everything is like the structure science of architecture, which generally presents various forms and combinations. Many excellent architects and structural engineers have learned new laws of space growth from disciplines such as physics and natural science. The laws of nature are often hidden reflection of social and economic development and solutions, which of course includes architecture. If they don’t present such a state, then it is very likely that there is a reason or purpose for them to do so. For example, the network of rivers is an orderly structure. Through the study of branch networks formed by rivers, I learned the mystery of the growth of many branch networks, such as Fractal Self-similarity, preferential growth at the tops, Avoidance of homogeneity, Diffusion-limited Aggregation, etc. Based on the understanding of fractal ecosystem, I tried to build an ecological, harmonious and sustainable skin structure by imitating the rules of biological evolution. Just as a river flows from a mountain into the ocean, with triangles as the initial unit, iteratively simulates rivers eroding land and developing branches. This network, which can grow indefinitely, is like a "blooming river" because it grows and expands like every branch of a river and is closely connected. This is not only a form of structure that conforms to the natural logic, but also a space deduction to stimulate imagination.

Energy saving passive ventilation and cooling provided by building structures KATONA Ádám1 ; KISTELEGDI István2 1

Keywords: spacious, hall like buildings, passive ventilation, passive cooling, CFD simulations, in situ anemometric measurements, validated model, prototype building development, passive bidirectional hybrid ventilation and cooling (PBHVC) prototype A simulation supported design and research investigation program was elaborated to develop passive bidirectional hybrid ventilation and cooling (PHDC) systems in commercial and industry buildings in warm and humid climate. A Hungarian industrial and office prototype building with unique aerodynamic design concept, shaping and operation served as a ‘reference lab’ for experimental measurements. In a first step, investigations compared the ‘pioneer’ reference building’s CFD model calculation results against monitored in situ measurement data during operation of the real building with three updraft passive ventilation towers. After calibration of the reference building’s CFD model, it was used as initial point for further simulation variations. Weather data of the validated, high efficient performing updraft ventilated model should be modified into warm and humid subtropical weather conditions, furthermore tower geometries will be transformed into downdraught ventilation and cooling structure variation. The vertical ventilation towers of the reference CFD model performed high efficiency in both upward as well as downwards direction. The next step proposes the development of a universal, theoretical building prototype with large-scale interior volume under warm and humid climate conditions (e.g. region of Shanghai). The building dimensions were enlarged from the reference hall’s 610 m2 to 6050 m2 net floor space. Since spacious interiors possess central areas in great distance from façades, frequently natural window and opening ventilation is impossible. Secondly, for most generic ventilation system, applicable in different wind distribution micro-climate situations, are independent of wind direction diversity. In order to meet these prerequisite, the towers should be able to provide both inlet and outlet for ventilation. Therefore, the concept of a bidirectional up- and downdraft passive ventilation and cooling tower system seemed to be optimal. In the monitored building, a drawback was registered at upstream airflows at the ventilation towers’ vertical walls in wind coming direction that slowed down the wind velocity at tower’s top. To avoid this contra-productive aerodynamic withstand-effect, the tower geometry was integrated into a pyramid-shaped roof geometry. A prototype unit works with two simultaneously operated similar coaxial ventilation towers: the one is responsible for fresh air supply and the other one for exhaust air outlet. Gaining promising simulation results about the passive bidirectional hybrid ventilation and cooling (PBHVC) prototype, these units were assembled into a larger modular hall system with 2 – 5 h-1 ACH.

On the detection and assessment of delaminations beneath overlays and thin courses in pavements KHAN, A.I.1 ; KEIHANI, R.1 ; KARADELIS, J.N.2 1 2

Centre of Built and Natural Environment, Coventry University Faculty of Engineering Environment and Computing, Coventry University

Keywords: pavements, delaminations (defects), infrared thermography, impact hammer testing Debonding of the top, thin course is a common mode of failure in modern road and pavement construction or rehabilitation. Improving the reliability and accuracy of two well-known methods, Infrared Thermography and Impact Hammer Testing, and using them jointly to detect and evaluate the bond condition between the top, thin layer and the base of a pavement can be viable, fast and economic, contributing to road safety and riding comfort. This article incorporates a quick state-of-the-art review of the existing wisdom and exposes the appropriate research niche. It integrates a preliminary (laboratory) investigation of the two aforementioned methods, backed by initial but useful numerical models. As a result, a number of tentative conclusions have been drawn and presented in a brief but comprehensive manner.

Impact of differential evolution parameters on optimization of hydro-thermal coordination KINCZER, Tomas; ŠULEK, Peter Department of Hydraulic Engineering, Faculty of Civil Engineering, Slovak University of Technology, Bratislava, Slovakia

Keywords: differential evolution, sensitivity analysis, optimization, hydro power plant Heuristic methods are one of the most used tool for optimization of problems. Proof of that is the fact, that they are widely used in chemistry, economy or energetics. Differential evolution belongs to the lately popular heuristic methods. It is a method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. It can handle difficult, large scale problems with many parameters like optimization of hydro-thermal coordination of hydro and thermal power plants. Like any other heuristic methods, differential evolution also have certain parameters. These parameters, among others, are scaling or weighting factor, crossover weight and size of population. The influence of these parameters on results of optimization using differential evolution is the focus of this paper. Hydro-thermal coordination of one hydro and one thermal power plant was used as an example.

Optimization of syntactic metal matrix foam manufacturing KOCSI Balázs; BUDAI István University of Debrecen

Keywords: syntactic metal foams, manufacturing, casting, metal foam, coated ceramical spheres In the past years, the application of metal foams has become widespread, it is not only used by aerospace field but also in everyday life. However, the manufacturing costs of metal foams are high, so interventions must be taken in order to reduce these costs. Such interventions can both increase the quantity of the produced foam (economic production quantity), and can also make the production process cheaper and more efficient. The aim of the current research is to make the above production process cheaper by reducing the mass of syntactic metal foam, as well as by optimizing its mechanical properties, which open opportunities in the field of construction, such as building earthquake resistant houses. The first step of the research is to create the skeleton of coated ceramical spheres. When this skeleton is prepared, alloy can be injected into its structure, it is what makes the liquid metal matrix stabilized. The metal casting can only be prepared if the ceramic spheres are coated with a thin metal layer. The novelty of this paper is that this manufacturing process can be executed without pressure, and by defining the position of the coated ceramic spheres can provide an opportunity for reducing the amount of the injected liquid metal matrix.

Total process time prediction in complex manufacturing environment KOCSI Balázs; PUSZTAI László; BUDAI István University of Debrecen

Keywords: total process time prediction, Simulation, scheduling The prediction of manufacturing total process time is rather complicated in complex manufacturing environment with conventional methods. The accurate prediction of total process time is a requirement in the fields of scheduling and process improvement. The aim of the research is to make a comparison among different types of total process time prediction methods and find the appropriate technique for production scheduling. The objective of the research is the comparison among linear regression and Monte-Carlo simulation. The efficiency of methods are presented by experimental results in a case study. In this three cases symmetric mean absolute percentage error is applied to describe the prediction error. The method which has the lowest error is presented in the article since it is capable of making accurate total process time prediction. Total process time prediction is an essential technique in different industrial areas such as the production scheduling, Business Process Re-engineering and Process Improvement.

Exploratory research on motivation of foreign engineer students of the University of Debrecen KOVÁCS István1 , PUSZTAI László2 1 2

Faculty of Economics and Business, University of Debrecen Faculty of Engineering, University of Debrecen

Keywords: international education programs, engineer students, motivation In the previous 5 years the number of foreign students on engineering programs at the University of Debrecen has increased exponentially (from 130 to 669), that implies challenges not just for Hungary, but for both the city and the university. On one hand, it is very costly to make the city more comfortable for foreigners, and it needs more efforts from every stakeholder. On the other hand, foreign students spend their money, enforcing a multicultural environment and facilitate high value-added production, that can boost the economy of Debrecen. In this paper a brief review of the related literature and the main results of the research are presented, which based on a survey of 283 foreign students of University of Debrecen. The questions are focused on demography, motivational factors and expectations about their potential job opportunities. The research is aiming at determining why they chose Debrecen and its university, and their willingness to stay in Hungary. The better understanding of their motivation can contribute significantly to the evaluation and development of the efficiency of scholarship programmes provided by Hungary. The paper explores hidden connections and correlation among variables by applying linear regression, hypothesis testing and descriptive statistics. The results show, the most important factor for choosing University of Debrecen is the public safety, while the least important is the attractiveness of Debrecen. Although the latter seems unimportant by the decision of coming to Debrecen, life in Hungary might be a decisive factor, since 40% of the students imagines having a job in Hungary (and 25% indicated Hungary on the first place).

Special architectural requirements of educational buildings KOVÁCS Péter; MOLNÁR Tamás; KÓSA, Balázs University of Pécs, Faculty of Engineering and Information Technology

Keywords: educational buildings; educational environment In the decades elapsed since the construction of the majority of educational buildings in Hungary, there have been various social, economic, and demographic developments that affect the utility of existing infrastructure. These changes present special requirements – those not met by existing buildings – setting a challenge to both architects and decision makers. The aim of this presentation is to analyze the various aspects of these developments and reflect on the extant architectural framework of education, serving as a basis for further investigations on ways architecture can enhance the learning environment.

Circular economy refers to a move from linear business models, in which products are manufactured from raw materials, used and then discarded, to circular business models where products or parts are re-used, remanufactured or recycled. Efficient allocation of resources can minimise waste production and decrease carbon dioxide emissions. The RFCS Research Project “REDUCE” of the European Commission (Grant Agreement number: 710040) goes one step beyond the mere material recycling and investigates, how the philosophy of the circular economy can be used in the case of steel and steel-concrete composite structures. One target of the research was to develop structural solutions that allow for demounting and facilitate the future reuse of structures or structural elements. In order to make steel-concrete composite structures demountable, bolted connections should replace the commonly used welded headed studs. Furthermore, the reusable parts should be designed to withstand repeated use. This contribution presents the underlying laboratory tests as well as the results of the supplementing numerical desktop studies. The outcome will provide valuable information for a future design guidance concerning the use of demountable shear connectors in composite beams.

Modeling of changes in runoff due to changes in forest composition LABAT, Marija Mihaela; FÖLDES, Gabriel Slovak Unversity of Technology, Faculty of Civil Engineering, Department of Land and Water Resources Management

Keywords: WetSpa, runoff, deforestation Assessing impact of forests on the hydrological cycle is a worldwide topic issue addressed by hydrologists and water managers. In the forest ecosystem, the transformation of precipitation into the runoff begins when rain drops on surface of the trees surface, from which it drops down to a surface of lower vegetation. The part of the rain evaporates from the surface of the plants, but some of it drops to soil surface, where it is either infiltrates underground or flows over the surface, forming a surface runoff. The fact that forest naturally accumulates water in the catchment area is known for ages. The recent researches show that on deforested areas runoff is increased, and on opposite, when an area is afforested, the runoff decreases. For the last decades many forests in Slovakia, especially in mountain river basins, were devastated mostly by wind calamites, but some of them were destroyed by snow calamites. The examined region was the basin of the Boca river, which is located in the district of Liptovský Mikuláš. This small river is the left tributary of the Vah river, it rises in National Park Low Tatras in central Slovakia at 1400 m above sea level. The area of the river basin is 82 km2, from which the forested area is about 80 The main aim of this paper is to analyze and estimate the changes in runoff process in this river basin for historical (before year 2004) and present land use. For hydrological modeling the model WetSpa (Water and Energy Transfer between Soil, Plants and Atmosphere) was used. This physically based model is used to simulate hydrological processes of precipitation, snowmelt, interception, surface runoff, evapotranspiration, infiltration etc. on a catchment scale. Total runoff and its components are calculated using the elevation, land use and soil type data, and it also vary with the soil moisture, storm duration and rainfall intensity. Since the model works on a daily time scale, it has a great potential to estimate the changes in runoff due to changes in land use and deforestation.

Visibility investigations at railway crossings MAGYARI Zsófia; FISCHER Szabolcs; KOREN Csaba Faculty of Architecture, Civil Engineering and Transport Sciences, Széchenyi István University, Győr, Hungary

Keywords: visibility investigation, railway crossing, LIDAR, photogrammetry, point cloud, road safety

Background One of the critical locations in the road network is the level crossing of railways where accidents are rare but their outcomes are in many cases fatal. According to the Webbal accident database 77 accidents have occurred in the last ten years in a rail road crossing where one of the participants was a railway vehicle and the other was a car. In these casualties 121 people were injured, 27 of which were fatal, 26 serious and 24 cases of light injuries were registered.

Objectives According the data is important to explore accident prevention opportunities at level crossings. This study examines this problem from the aspect of visibility. The purpose of this study is to apply three-dimensional visibility analysis based on point clouds for railway crossings, taking into account the specific requirements of railways.

Methods The authors used two methods for producing point cloud models: terrestrial laser scanning (TLS), and photogrammetry with UAV device. The second method was complemented by GPS measured ground points. By comparing survey experiences and evaluation procedures, the advantages and disadvantages of data collection methods can be clearly demonstrated.

Results The data analysis revealed the visibility problems of the examined level crossing and the model can be used to suggest necessary interventions. The impact to visibility of the planned measures can be assessed by the model. By comparing the visibility parameters produced by the different methods it is possible to determine whether the absolute accuracy of the measurement procedure actually influences the impacts of the visibility obstacles.

Estimation of the mean annual flood estimation using two pooling methods MARKOVÁ, Romana; NÉMETOVÁ, Zuzana; KOHNOVÁ, Silvia Slovak University of technology in Bratislava

Keywords: mean annual flood, cluster analysis, regional flood frequency analysis, top-kriging The objective of the study is an estimation of the mean annual flood by using two pooling scheme approaches, i.e. the index-flood method and the top-kriging. The concept of these methods is to estimate mean annual flood at ungauged locations using information taken from gauged sites located within the same homogeneous pooling groups. Index-flood method represent the most popular type of regional flood-frequency analyses methods. Regional floodfrequency analysis is consider as important and popular method for estimating different hydrological variables at ungauged sites or estimation at gauged sites where historical records are available. The crucial part of regional frequency analysis includes the pooling of catchments into homogeneous pooling groups. The second used in the study method, is, top-kriging. It is geostatistical method used for spatially interpolating a range of different hydrological variables. The study area comprises of 106 gauging stations from the whole territory of Slovakia. The selected stations have the observation period of annual maximum discharges from 1961-2010. Identification of homogeneous pooling groups was performed by using the nonhierarchical k-means clustering algorithm. The optimal number of clusters is determined by the silhouette method. For the clustering the similarity of catchment characteristics flood seasonality characteristic (and climatic characteristics were used. As result, eight homogeneous pooling groups clusters were identified. Finally the results of estimated mean annual floods by pooling methods were compared with the observed data. Top-kriging provides better results by estimation of mean annual flood than classical index flood method.

Energy performance evaluation of the conventional external wall materials applied on the Algerian residential building facade - Hot and dry climate MESSAOUDA, Rais; BARANYAI Bálint; HALADA Miklós University of Pécs

Keywords: energy consumption, facade, improvement of residential buildings, external wall materials, hot and dry climate. The building facade becomes an integral part of the bio-climate architectural concept, it should be able to respond and adapt its properties and components with the immediate environment, therefore to increase the building energy efficiency. The Algerian context is experiencing a serious crisis in the housing sector, consequently, development prospects of housing which must be done in a short period and lower cost lead to apply external wall materials, techniques, and general building design without addressing the local climate conditions. Consequently to this, the residential buildings in Algeria are responsible for 33% of the final energy consumption. The main objective of this study is to investigate and evaluate the performance of the conventional external wall materials applied to the contemporary residential building facade in Algeria. Thus to find the most appropriate external wall layers for the residential building in hot and dry climate, therefore to optimize their cooling energy efficiency in the summer period, using a dynamic simulation with Vi-Suite add-on on Blender 3D software.

Classic object oriented modeling design via fluid multi-level meta-modeling MEZEI Gergely1 ; THEISZ Zoltán2 ; BÁCSI Sándor1 ; URBÁN Dániel1 1 2

Budapest University of Technology and Economics evopro systems engineering Ltd.

Keywords: object oriented modeling, meta-model based design Principles of multi-level meta-modeling facilitate semantically correct design and implementation of complex modeling problems by avoiding accidental complexity which is so abundant within legacy UML and state-of-the-art MOF modeling techniques. Since incumbent modeling methodologies are deep-rooted in Object-Oriented Programming (OOP) paradigms, and thus implicitly share many design techniques with popular OOP languages such as Java, Javascript and C++, there is a practical research question of how multi-level modeling concepts can effectively emulate and may theoretically unify many of those well-known OOP elements. Hence, in this paper, we investigate the most well-known OOP design primitives from the perspective of meta-model based design and make a detailed comparison between their classical two-level and novel multi-level modeling applicability. Our handling of the research question is rather practical than philosophical, thus we always try to draw parallels via concrete model examples written in UML and/or Ecore against their peers specified in Dynamic Multi-Layer Algebra (DMLA), our formal multi-level modeling framework.

Shear connection experimental and theoretical research MICHÁLEK, Peter; BUJŇÁK, Ján University of Zilina, Faculty of Civil Engineering, Department of Structures and Bridges

Keywords: composite structure, connection, slip, push-out test The resistance of steel-concrete composite trusses is considerably influenced by shear connectors and interaction between the steel beam and the concrete slab. To create the interaction between the steel parts and concrete, it is necessary to prevent the relative slip at the steelconcrete interface using the shear connectors. Push-out tests reflect more real effect of the longitudinal force and the distribution of the shear force between the steel section and the concrete slab. The finite element analysis can be used to investigate numerically this structural system behavior, exploiting several computer procedures.

Gait analysis with optical sensors MÜLLER Péter; SCHIFFER Ádám Faculty of Engineering and Information Technology, University of Pécs

Keywords: gait analysis, image processing, sensor Gait analysis is a complex task and requiring a well-defined, dedicated equipment and environment. The basics of analysis can be done visually by involving an expert or a movement therapist. The advance analysis of movement often obtain data from technology, for example opto-sensors, depth or high-speed cameras. Using the technology and therapists experience the results of the research able to give feedback in real time about the movement phases. In this project an Xbox ONE Kinect sensor is used for monitoring the gait cycles, and with the aid of signal processing methods, the joint angles, angular speeds and different trajectories can be calculated, which are result in the human gait cycle phases.

Simulation method for delay-insensitive asynchronous digital networks NAGY Attila1 ; KERESZTES Péter2 1 2

Széchenyi István University, Department of Mechatronics Széchenyi István University, Department of Automation

Keywords: delay-insensitive (DI) asynchronous networks, simulation, VLSI design The proposed simulation method allows to investigate the delay-insensitivity of asynchronous digital networks by substitution of the delays of the interconnections and gates with pulse controlled sample-and-hold switches. The preparing of the investigated circuits for the simulation can easily carried out with defining the register-transfer level VHDL model. The activation of the inserted switches happens after each other using the delta-delay mechanism of the simulator. The sequences of activation can be automated by a backtrack algorithm which can be linked to Modelsim simulation environment using its foreign language interface (FLI) capability.

Graph approximation on similarity based rough sets NAGY Dávid; MIHÁLYDEÁK Tamás; ASZALÓS László University of Debrecen, Faculty of Informatics

Keywords: graph approximation, rough set theory, correlation clustering Based on the available information in many cases, it can happen that two objects cannot be distinguished. If a set of data is given and in this set two objects have the same attribute values, then these two objects are called indiscernible. This indiscernibility has an effect on the membership relation, because in some cases it makes our judgment uncertain about a given object. The uncertainty appears because if something about an object is needed to be stated, then all the objects that are indiscernible from the given object must be taken into consideration. The indiscernibility relation is an equivalence relation which represents background knowledge embedded in an information system. In a Pawlakian system this relation is used in set approximation. Correlation clustering is a clustering technique which generates a partition. In the authors’ previous research the possible usage of the correlation clustering in rough set theory was investigated. The clusters contain objects that are usually similar to each other, so the partition can be understood as the system of base sets. In this work the authors show a way to approximate graphs based on system gained from the correlation clustering.

Investigation of parameters in simulations of CEP controlled attosecond pulse generation NAGYVÁRADI Anett1 ; TIBAI Zoltán2 1

Department of System and Software Technologies, Faculty of Engineering and Information Technology, University of Pécs 2 Institute of Physics, University of Pécs

Keywords: free electron laser, attosecond pulse generation, simulation The basic principle of FEL (Free Electron Laser) can be described through the generation of synchrotron radiation, where electrons with relativistic velocity (generated by linear accelerator - LINAC) go through a periodic lattice of alternating magnetic dipolar fields, so called undulator and emit electromagnetic radiation which wavelength or frequency can be controlled by the undulator parameter and the energy of the bunch (resonant wavelength). Undulator radiation of relativistic ultrathin electron layers generated by laser-driven energy modulation eventuate to producing few-cycle attosecond pulses with arbitrary waveform in the extreme ultraviolet (EUV) spectral range. Even shorter pulses (attosecond) are proposed based on theoretical calculations and simulations. These methods are under development and calculations and simulations are made in these constructions with special simulation codes like Genesis (3D FEL simulation code), Simplex (simulating the amplification process of free-electron lasers), Astra (Space Charge Tracking Algorithm), CSRTrack (particle tracking), Elegant (ELEctron Generation ANd Tracking). With our setup isolated waveform-controlled extreme ultraviolet attosecond pulses at 20 nm with 90 nJ energy and 80 as pulse duration, and at 60 nm with 200 nJ energy and 240 as duration can be generated. The generation of coherent, high intensity, ultrashort pulses in the Angstrom wavelength region is a very important goal in scientific research projects and it opens up new frontiers across many parts of science.

Interrogating modernization tendencies in architecture and street infrastructure during the Tanzimat reforms through the use of archive documents: the case of Kosovo NAVAKAZI, Vlora; JERLIU, Florina University of Prishtina

Keywords: architecture and street network in 19th century, government buildings, Tanzimat Reforms, Kosovo Modernization tendencies in architecture and street infrastructure were introduced in Kosovo during the Tanzimat Reforms, enforced by the Ottoman Empire in the late 19th century. Lack of original archive documentation until now has impeded scientific approach to urban and architectural analysis, for which reason, Kosovo cities often face difficulties in documenting their historical and cultural continuity. In order to fill the gap of knowledge about urban built heritage of 19th century in Kosovo, this paper uses and analyzes original visual archival documents, retrieved by author from the Premiership Ottoman Archives (Başbakanlik Osmanli Arşivleri - BOA). Analyses show that construction of street network and public buildings was realized in line with the needs arising from new administrative division imposed by the Tanzimat Reforms. While street network intended to connect Kosovo settlements, public buildings and especially the government buildings built in Prizren and Prishtina, former centres of Vilayets, intended to introduce new building standards and a new language of architecture. Interrogation of modernization tendencies in architecture and street network in Kosovo during this period is important for establishing a continuity of future planning development, as well as in narrating modernization tendencies that occurred in Kosovo in line with other parts of the Late Ottoman Empire territories in the Balkan.

Investigation of glued-insulated rail joints with fibre-glass-reinforced, resin-bonded fishplates in laboratory NÉMETH Attila; FISCHER Szabolcs Department of Transport Infrastructure, Széchenyi István University, Győr

Keywords: laboratory test, railway, insulated rail joint, fibre-glass reinforced fishplate, polymer composite

Introduction In this paper the authors summarize the three-point static and three-point dynamic fatigue laboratory bending tests’ measurement results related to APATECH branded glued insulated rail joints with special fibre-glass reinforced plastic (polymer-composite) fishplates. During the previous research work the static three-point bending tests were performed on three different rail profiles (MÁV48, 54E1 and 60E1) with three specimens on different support bays before and after 3.5 million loading cycles (fatigue test). After the research the polymer-composite fishplated glued-insulated rail joints and control steel fishplated rail joints were built into the No. 1 main railway line (Kelenföld-Hegyeshalom) in Hungary at four different railway stations. The accurate time could not be determined when the polymer-composite fishplated glued-insulated rail joints reach the end of their lifetime as the result of previous research. In this article the investigation of deterioration process of glued-insulated rail joints is demonstrated.

Research methods The authors introduce the results of the additional three-point static bending tests and additional three-point fatigue (dynamic) bending laboratory tests [3]. These tests were executed with additional three pieces of specimens (compared to the previous research), one specimen for MÁV48, one for 54E1 and one for 60E1 rail profiles. During these laboratory tests the considered parameters, characteristics were the followings: • static three-point bending test before fatigue; • three-point fatigue test with 0.5 million cycle; • static three-point bending test after fatigue; • static vertical displacement (deflection) measurement after every 0.5 million cycle until 3.5 million cycle (as well as before the first dynamic tests, too); • vertical displacement measuring at 7 different points; • 13 different bay values;

• from older research: investigation of steel fishplated glued-insulated rail joints on that were already done 3.1 million cycle fatigue tests – execution of additional three-point dynamic tests with 0.4 million cycle; • after 3.5 million cycle – additional measurements on asymmetrically support bays with all the rail joint specimens. The goal was to evaluate the more accurate deterioration process of fishplated rail joints.

Summary/results The authors represent the results of laboratory tests on glued-insulted and steel fishplated rail joints. With the aim of this research the authors would like to determine the ultimate lifetime of the investigated rail joints, e.g. as long as they can be safely held in the railway track without damage.

Analysis of corrugated web composite girders with innovative shear connections NÉMETH Gábor; KOVÁCS Nauzika Budapest University of Technology and Economics

Keywords: steel-concrete composite, push-out test, shear connection The application of corrugated web as the web plate for girders, thanks to its numerous favorable features, modernizes the construction of steel-concrete composite and hybrid girders and provides an alternative, competitive structure for small span beams compared to conventional precast reinforced concrete structures. The corrugated webs makes more economical to use composite structures for medium and large span beams, as well. The aim of the PhD research is to perform experimental and numerical analysis of corrugated web composite girders with new type of shear connectors, to develop mechanical model and recommend design method of the shear connection. In 2017, full-scale push-out tests were performed in the Structural Laboratory of the Department of Structural Engineering. This involved 57 specimens, both composite and hybrid. The results of the experimental research serve as the background for further numerical research. Several structural parameters were examined during the experimental program, including the geometry of the corrugation and the shear connector. According to the experiments, the structural behavior and failure modes were evaluated, the behavior of different type of shear connectors were compared. Numerical models were created for a few specimens, the validation of the model were also performed. The results of the experiments on the basis of the load capacities and force-relative displacement diagrams were evaluated and compared with the numerical results with good coincidence. The strategy, implementation and results of the experimental tests will be presented along with the effect of parameters on structural behavior during the research. Also, the finite element model and its properties will be discussed. The comparison of the experimental and numerical tests will be presented, including the structural behavior, failure modes and load capacities.

Parallel universes - as the possibilities of liberation of creativity in architectural design NÉMETH Pál; TARR Zsuzsanna Faculty of Engineering and Information Technology, University of Pécs

Keywords: art, architecture, design, creativty Parallel universes exist... But if not, the intention of human creativity to create them cannot be denied. The focus of our topic is not the parallel universes, i.e. the possibilities of physical existence of the multiverse, but the creative process that creates them. It is an undeniable fact that the visual projections from various works in science fiction or fantasy genres have affected contemporary architecture and design in several aspects. Our performance summarizes the research that has been running for several years, in which the architecture students created parallel universes and discusses how they explore the question of how their creativity has changed when only their own imagination limits the architectural creation.

Study of hazard probability in high speed FPGA implementations for particle detectors ORBÁN János; FÜZI János; KISS Gábor MTA Wigner FK

Keywords: FPGA, particle detection, high count rate Time to digital converters are essential components for position sensitive particle detectors using delay-line method for position encoding. These devices have been developed during the last decades increasing the count rate capabilities by lowering its dead time thus handling the modern, high flux particle sources. Implementation on FPGA is a frequent solution thanks to the high parallelization capability providing very low dead times. Further features could be also important for certain applications like event positioning errors due to logical hazard. Count rate capability and probability of hazard are experimentally studied in various architectures implemented on low-cost FPGAs.

Air entrainment and free surface modelling of fully turbulent flow near the broad-crested weirs ORFÁNUS, Martin; RUMANN, Ján Faculty of Civil Engineering, STU in Bratislava

Keywords: broad-crested weir, physical model, CFD, hybrid modelling, hydraulic research The research was carried out at the Department of Hydraulic Engineering , Faculty of Civil Engineering STU in Bratislava with close cooperation with the Institute of Water Structures, Faculty of Civil VUT Brno. One of the important goals was the determination of the most accurate approach related to the CFD modelling of the air-water interaction. Research consists of two main research methods to ensure the accuracy, set up the possibilities of cooperation and the results control. The first method was the physical model of broad-crested weir installed in collapsible canal in hydraulic laboratory and the second was numerical CFD model of broadcrested weir created in same scale. In free surface flows the air entrainment phenomena plays an important role. Air entrainment is effecting the volume fraction, velocity field, energy dissipation and many other parameters related to dynamic behaviour of water near the crests. A different approaches were carried out to identify most accurate CFD setup compared to physical model measurements. Compared results and the accuracy assessment is summarized and the best CFD parameterization is recommended.

University of Pécs, Breuer Marcell Doctoral School University of Pécs, Faculty of Engineering and Information Technology

Keywords: campus design, urban design, university development, Pécs, University of Pécs To define the principles of design, first we have to clarify what the campus is and who the users are. After clarifying these basic terms, we must look at the campuses of today’s leading universities. We have to define those basic types of campuses which later on allow us to define the guiding principles of design. Last, we have to look at the relations between Pécs and the university and see to what extent the principles apply in the case of its university. Further on, the analysis of the respective aspects of city planning is also required to understand the development and functioning of the campus. This allows us to define the guidelines of development of PTE and other campuses.

CFD analysis and heat transfer characteristics of finned tube heat exchangers PETRIK Máté; SZEPESI L. Gábor, JÁRMAI Károly University of Miskolc

Keywords: CFD analysis, finned tube, heat transfer, automotive radiator This present paper aimed to fulfil the parametric analysis on the heat performance of a compact automotive radiator using computational fluid dynamics (CFD). The analysis has been carried out at different air velocities with different fins modelling such as real fins and as porous media. The used CFD software to this study was SC-Tetra. The fluids are incompressible, three-dimensional and turbulent. The geometry of the fins has a high impact to the heat transfer coefficient and the heat performance, so the shape, the size and the thickness of the fins are compared to each other. The results show that the ratio of the fin pitch, the wall thickness of the fins, the number of the fins, the flow depth and the geometry of the tube are the main factors of the heat transfer. Our goal to find a dependable Nu-number correlation for this type of heat exchanger and using this function to find the optimal shape of the radiator, which is able to cool the cooling liquid to the necessary value and has the smallest weight.

The effects of Chinese traditional beliefs: the application of the Feng Shui theory from ancient to modern in architectural design QIANG, Gu1 ; HUTTER Ákos2 ; ZOLTÁN Erzsébet Szeréna2 1 2

University of Pécs, Faculty of Engineering and IT, Breuer Marcell Doctoral School University of Pécs, Faculty of Engineering and IT

Keywords: Chinese traditional beliefs, Feng Shui theory, architectural design Chinese civilization has accumulated Chinese wisdom bit by bit, to gain full understanding of the origin of nature, the world. The Feng Shui theory came out from Chinese civilization and was still made use in architectural design from ancient to nowadays. The main content of this research is to introduce the definition of the Feng Shui theory; the connection between the Feng Shui theory and architectural design from ancient to modern. Also, this presentation will determine that the Feng Shui theory has strong relationship with science. Chinese traditional beliefs have a close relationship with nature. Taoism is not only the core of Chinese traditional beliefs, but also stands for the philosophic thinking of China. In the meantime, Taoism has a close relationship with nature. Taoism advocates that everything in the world comes from the origin of nature; it proposes the harmony between humans and nature. Feng Shui was the standard of Chinese architectural design in the past, similar to the building codes in America. Nowadays, many architectural design, urban design and landscape design projects use the similar design methods and concept which can be explained in the similar way from the Feng Shui theory, even they are in different cultural background. The research of the application of Feng Shui theory in contemporary design is significant. Each culture has its own unique features; each culture is an element to inspire designers. If the Chinese culture can be acceptable in contemporary architectural design. To find out the advantages of a local culture and to determine how to keep the balance between local culture and contemporary architectural design will offer another rational design methods for designers to use and benefit the development of architectural design.

The role of adaptive reuse in contemporary architecture RÁCZ Tamás PTE Breuer Marcell Doctoral School

Keywords: adaptive reuse, urban planning, architecture Adaptive reuse has become a key issue in the architecture in the last decades. Many theories were published, concerning its importance, and the reason why we should highlight the phenomenon of reusing existing buildings. However the most significant and eye-catching product of the refurbishment is the renewed building itself, the process should be investigated from more aspects, such as the buildings new role in the urban fabric, economic and ecological needs, and its effect on the social surroundings. My goal is to emphasize the main conceptual reasons of deciding not demolishing the existing, then designing a new building, through case-studies connected to adaptive reuse.

Keywords: Building Information Modeling, measuring method, panel building, laser scan, photogrammetry Nowadays the panel buildings need to be refurbished. The measuring process is necessary before starting to design the flats. There are several plans about the construction phase, but most of the flats interior was changed by the owners. In this case the traditional surveying can be useful, but the modern technologies could be more efficient. The time, accuracy, costs and the expected knowledge of the users are the factors which give the methods efficiency value in this research. A case study will be presented, where all of the techniques were tested. The Building Information Modeling technology helps to compare the processes, because the goal of the measuring was a 3D BIM model.

Protecting urban memory, inheriting urban context REN, Chao Breuer Marcel Doctoral School, Faculty of Engineering and Information Technology, University of Pécs

Keywords: urban memory, urban context, heritage, story Cities exist by urban memory which is nostalgia and also an epitome comprised by the massive fragment of people’s daily life. The unique urban stories and culture heritage lead to their very distinctive features. There are no two exactly the same cities in this world because the urban memory of each city cannot be replicated or replaced by any other cities. The collective memory is created and shared by many people and it is a symbol of the city. A city’s core spirit sublimated from its urban context. The context enables people to find the perception of affiliation while looking into the collective memory of the city. In the process of urban development in Contemporary China, a series of problems of urban context development have emerged. Instead of presenting diversified urban context, Chinese cities suffer from the modeling design and end up with a situation of serious likeness. The loss of urban memory makes the city lose its unique character and soul, and it is urgent to protect and inherit the urban context. Urban memory is an important part of the urban context. If the architectural space carries the history of the city, then the urban story passed on by people in the urban context. The urban context is not only the witness of urban history but also the storage of urban people’s memory. The urban context is the spiritual dependence of people to recall the past, to imagine and to create the future. Urbanization brings deficiency in collective visual memory and urban memory. It is necessary for builders to protect and pass on the memories of these cities. The intention of design and creation should be combined with the regional geography characteristics, and integrated with the stories of regional cultural heritage. The designer guides the public to participate in the inheritance of the urban context so that the public can resonate emotionally with the city’s memory, thus creating a sense of belonging. Meanwhile, the government should formulate corresponding policies and regulations to support the project of the urban context.

Preprocessing approaches in DTW based signature verification SALEEM, Mohammad; KŐVÁRI Bence Budapest University of Technology and Economics, Department of Automation and Applied Informatics

Keywords: online signature verification, preprocessing, DTW Online signature verification is widely used in authentication and identification. Many of the most popular approaches are built on dynamic time warping (DTW) as it shows promising results. However online verifiers still leave place for improvement. To improve the results of DTW based verifiers, researchers have applied different preprocessing steps. To evaluate and compare the effects of these preprocessing algorithms we implemented some of them. Scaling, alignment and using different dimensions (X, Y, XY) and their combinations (24 combinations) were applied during our experiments. The methods were tested using the SVC2004 signature corpus and the results have shown that the error rate may vary between 28% (no preprocessing) and 13% (alignment used and tested on Y dimension). This means that using the preprocessing methods the results enhanced by 15%, this enhancement can be improved by using more preprocessing methods.

Hydrological modelling for the interaction between groundwater and surface water along the Drava floodplain, Hungary SALEM, Ali1 ; DEZSŐ József2 ; EL-RAWY, Mustafa3 1

Civil Engineering Department, Faculty of Engineering and Information Technology University of Pécs Institute of Geography, Faculty of Sciences, University of Pécs 3 Civil Engineering Department, Faculty of Engineering, Minia University, Minia, Egypt 2

Keywords: river incision, MODFLOW-2005, replenishment, water budget River Incision in the lower section of the Drava River increases the drought hazard through lowering the groundwater level in the adjacent floodplain. We use Ground Penetration Radar (GPR) and satellite images to evaluate the sedimentological sequences of the floodplain. A three-dimensional finite-difference package MODFLOW-2005 with ModelMuse as a graphical interface is utilized to assess the water budget of the Cún-Szaporca oxbow lakes in the Drava floodplain. The model is calibrated with a correlation coefficient of 0.94, a mean absolute error of 0.08 m, and a mean error of -0.03 m. Different water resources management scenarios through lake replenishment are also discussed. We identify an increase in the lake water level by 1 m which resulted in increasing the aquifer recharge from the lake by 745.59 m3 d-1 and raising the average groundwater level by 0.77 m. The results also shows that the model is applicable for planning and management the water resources in the study area.

Graph systems in architecture SÁRKÖZI Réka; IVÁNYI Péter; SZÉLL Attila Béla University of Pécs, Faculty of Engineering and Information Technology

Keywords: parametric design, architectural pattern, graph theory, topology The aim of this presentation is to introduce the graph interpretation of architectural patterns and structures, and present their different types of topological characteristics. The transformation of patterns and structures into graphs maintains the topology but removes the geometrical properties. This solution allows the examination of different architectural patterns in a clear, universal way, without analyzing the material and structural role of the construction, although these factors have a great impact on the topology. The graphs of architectural patterns usually contain vertices with close to equal adjacent vertices, but special architectural or structural solutions can cause different topological build-up. In this presentation, architectural examples are introduced, represented by both usual and special graphs, and the characteristics of these graphs are also analyzed.

Protect the architectural heritage in fast-growing China SHASHA, Liu Faculty of Engineering and Information Technology

Keywords: architectural heritage, development, protection Architecture is a monument of human culture. Architectural heritage is not only a manifestation of urban culture, but also a microcosm of a country or region. In the past 30 years, many cities have undergone large-scale development. In China, hundreds of new towns have appeared on the ground, and thousands of houses have been built. The changes in the appearance of the town is shock the word. At this rapid development and dramatic changes moment, many outstanding historical and cultural heritage buildings have experienced ruthless destruction. After the end of the last century, there are many architectural heritage sites due to the protection and remediation has achieved certain results, but with the improvement of people’s living standards, the rise of tourism. People want more modern living conditions, rural construction began to learn how the construction of urban buildings. The government wants to create local characteristics and make the heritage land important tourist attractions that began to be keen on the development and use of architectural heritage, but also because of the lack of professional construction personnel and quick-looking social situation, a new round of protective damage has been formed. This paper attempts to find out the reasons form the present situation of Chinese architectural heritage by analyzing the process of globalization and combing the characteristics of Chinese traditional culture, summarizing the experiences and lessons in the process of European architectural heritage protection, and provides reference and inspiration for the future development of architectural heritage Protection.

Stereo vision in ragweed leaf segmentation STORCZ Tamás; ERCSEY Zsolt; VÁRADY Géza Department of System and Software Technology, Faculty of Engineering and Information Technology, University of Pécs

Keywords: stereo vision, leaf, ragweed, matching range, point cloud Stereo vision gains advantage with better and cheaper available passive optical hardware devices. The main benefit of stereo vision is that three dimensional (3D) images can be created and spatial information can be accessed about the investigated objects. Even if objects have similar hues, additional 3d dispositional information may help to perform more efficient segmentation and geometric correction can be applied to the considered object. The invasive common ragweed (Ambrosia Artemisiifolia L.) today is the most widely spread weed in Hungary. Because of its economic damage as well as human infection its automatic detection is an important research issue. It is well known from plant decisive works, that leaves bear the primary characteristics of the species. Therefore, optical recognition of ragweed leaves is in the primary focus of the current study. Since ragweed plants have leaves very close to each other, moreover these leaves are located in a way that they occlude and overlap each other, their segmentation is very difficult. Even though various plants may vary widely concerning their colour range, the similar colour tint within one entity even makes the segmentation more problematic. As part of an optical recognition investigation, stereo vision problems were considered in connection with ragweed leaves. In this paper it is investigated how 3D point cloud generated by stereo vision could be used in plant and/or leaf segmentation. Stereo matching range was deeply examined and the corresponding additional information was used to support leaf segmentation. Based on the analysis performed during this work, it is clear that additional information gained from stereo vision effectively supports the segmentation of ragweed leaves.

Living spaces - Changes in functional aspect SYLEJMANI, Mimoza UBT

Keywords: multi-storey residential buildings, function, interior design, Kosovo Providing appropriate housing units remains one of the biggest challenges for architects. The economic conditions are among the factors that in the Republic of Kosovo have influenced the functional and spatial change of multi-storey residential buildings. Bearing in mind that over time the economic conditions, the requests and the needs of the communities change, this pulls the changes away mentioned above. The construction of multi-storey and individual dwelling buildings, as well as those with other destinations in city centers, is a very delicate issue. On the other hand, the need for renovation and new destination of existing residential housing is becoming an integral part of Kosovarian society every day. The issue is somewhat more sensitive to residential multi-storey buildings, where surfaces of usability areas are more limited. The next challenge for architects remains the treatment of these existing spaces, adapting them in harmony with the demands of the new generations - the social and social changes that our country faces. The whole effort to achieve something more comfortable is realized through the treatment of housing spaces not only in the horizontal direction but also in the vertical one, through transparency in architecture.

Optimizing electricity usage in a smart household based on mixed integer programming and model predictive control TAIK, Salma; KISS Bálint Department of Control Engineering and Information Technology, Faculty of Electrical Engineering and Informatics, Budapest University of Technology and Economics

Keywords: appliance scheduling, optimization, time of use (ToU) pricing, mixed integer programming (MIP), smart grid, model predictive control (MPC). Reducing and balancing the energy consumption has been considered a sensitive topic in the last decade for researchers from around the world. Many approaches have been introduced investigating methods and algorithms, such as Real-Time Pricing, and energy box scheduling (eBOX), for decreasing the energy usage in the household which is beneficial for the environment and for the consumer. The fact that many home appliances need to be plugged into an electricity source with the aim of running one or multiple operations throughout the day, represents a challenge for the utility company to supply the sufficient amount of power to meet the demand side. Consumers are used to constant price levels and they are unwilling to optimize the device scheduling for dynamic Time of Use (ToU) tariffs. This may cause a grid-wide unwanted demand-side surge of electric power. Supposing a dynamic ToU pricing strategy by the utility company, a consumer side optimal scheduler is proposed for a set of smart home appliances, including the charging of an electric vehicle. The optimization is based on the mixed integer programming algorithm. This scheduler may take into consideration the user’s preferences on the earliest powering on and latest powering off for each appliance. Scheduling of the on/off type home appliances leaves a dynamical variable power margin for the operation of the electric heating system in the apartment. To cope with the dynamical constraints of the input and with the dynamic ToU pricing, a model predictive controller (MPC) is developed for the heating system. Simulations show the energy efficiency along with a reduced electricity price of the strategy proposed.

Integration of terrestrial laser scanning and aerial photogrammetry - case study TKÁČ, Matúš; MESÁROŠ, Peter; MANDIČÁK, Tomáš Technical University of Košice, Faculty of Civil Engineering

Keywords: terrestrial laser scanning, laser scanner, digital data, aerial photogrammetry, drone, point cloud In the context of modern technologies in civil engineering industry we often meet with concepts of digitizing and a three-dimensional space. The three-dimensional space we can nowadays capture with special 3D laser scanners. Laser scanning, also called high definition surveying (HDS), is a method of high – accuracy mapping or reality capture that uses laser beams to quickly capture complete detail of the entire building construction project. This detailed 3D representation of the existing building construction if often called a point cloud, also called Dense Digital Surface Model (DDSM) where each point is represented by a coordinate in 3D space. One of the key advantages of laser scanning is the ability to quickly obtain large amounts of data in a short time, allows enhancing the design process, speeds up and reduces data collection errors, saves time and money and thus makes it an attractive alternative to traditional data collection techniques. Laser scans are a great tool, but not always as helpful as you would hope. First, they have the same problem as visual surveys-if you can’t see it, you can’t scan it, in other words, the laser beam from the scanner can’t measure a certain part of the surface of the structure if this part isn’t in the scanner’s field of view. In particular, we are talking about the surfaces of the roof structures because every roof has a different shape, size, height, angle, etc. In this case, the resulting point cloud from the roof structure may contain no information from the roof surface. How to deal with this problem? A possible solution is a combination of two technologies, terrestrial laser scanning and aerial photogrammetry. Aerial photogrammetry (or airborne imagery) means taking of photographs from an aircraft or other flying object. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones") and other. The aim of this paper is to describe the methodology of integration of terrestrial laser scanning with aerial photogrammetry using a drone. As a reference building for this methodology, the premises of Faculty of Civil Engineering, located in Košice, Slovakia was chosen.

Cellular automata simulations for modeling communication in biological systems TÓTH László1 ; KRESZ Miklós2 1 2

University of Szeged University of Szeged

Keywords: communication, cellular automata, complex dynamic systems, biological networks In live, open, dynamic biological systems, questions arise how we can combine complex elements of material, energy, and information in a way that it can operate a well-defined process (e.g. the flow of information in a tissue). The process proceeds easily for simple patterns, but for more complex networks require unique models - sometimes cellular automaton methods, where the cells can be biological properties (e.g. temperature, pressure). During our research, we realized that if a property is fixed, then other values, conditions will be determined in different measures. The basic question is how complexity change when the size of the biocell-organization (e.g. tissue) is increasing. For this, a program has been implemented with which can analyse the bound of the funcionality changing of cells or organs.

Comparison between CSS and GSAP through web animations UNGUREANU, Anca; LUNGOCI, Carmen; HELEREA, Elena Faculty of Electrical Engineering and Computer Science, Transilvania University of Brasov, Romania

Keywords: CSS, GSAP framework, animation The idea for this project is to find and use animations in web design through different frameworks and techniques. In order to that, the CSS language is compared with a new framework, called GSAP. The benefits of both have been discovered, the comparison between CSS, HTML and GSAP techniques has been done. Animations allow designers to change the coordinate space the appearance of CSS styled elements, can move the elements to a new position, rotate it, tilt it, or scale it in 2- and 3dimensional space. Animations give the ability to make changes to HTML elements dynamically through CSS. Translating an element means moving it to another location. There can be translated the elements horizontally with translateX(), vertically with translateY(), or both at the same time as translate(). For example, if an element is moved 100 pixels to the right or 50 pixels to the bottom, each motion can be specified with separate functions, as in the example: Transform: translateX(100px) translateY(50px). Web animations, finally, allow multiple actions, such as: gradually change from one style to another of an element; CSS properties changes; CSS animation, key frames settings for the animation. Adding a class and using CSS3 transitions and animations is often used for simple effects. For something more complex, GREENSOCK (or GSAP) gives a precise control and nested timelines. Both CSS3and GSAP offer good results, but GSAP workflow is much more suitable and maintainable for a creative code of animations.

Influence of the recycled-concrete aggregate’s coating layer thickness on the properties of concrete URBÁN, Karol; SIČÁKOVÁ, Alena; KOZLOVSKÁ Mária Technical University of Kosice, Faculty of Civil Engineering, Kosice, Slovakia

Keywords: concrete, triple mixing, recycled concrete aggregate, coating layer, curing time, discharge time, The worse quality of recycled concrete aggregate (RCA) - based concrete can be eliminated by specific mixing approach. When preparing concrete using triple mixing technology, the typical process is the coating of RCA by thin layer of fine-grain paste in the first step of mixing, to improve the surface quality of RCA. The properties of such concrete are influenced by the composition and thickness of this coating layer. Also, practical mixing and delivery of concrete could affect the properties of ready concrete due to prolonged mixing/discharge time. In this paper, the RCA was coated by 2 kinds of paste (cement and cement + fly ash), while two different thicknesses were applied (150µm and 250µm). Following parameters of concrete were tested after 28 days of curing: density, compressive strength, water absorption capacity and capillarity, while 2 sets of samples were prepared: immediately after mixing, and in 90 minutes after initial mixing (influence of prolonged mixing). These parameters were discussed in terms of the thickness of coating layer.

Spatial tessellations based on compound models of the Platonic and Archimedean solids VÖRÖS László Department of Visual Studies, MIK, PTE

Keywords: Platonic solid, Archimedean solid, hyper cube, tessellation, fractal Elements of subsets of a set of Platonic and Archimedean solids can fill the space periodically. Eight initial edges of a 3D model of the 9D cube can be arranged rotationally symmetric around the ninth one. Edges of the model can be parallel to the edges of the above solids. The 3D models of the lower dimensional parts of the 9D cube are construable based on combinations of the 9 initial edges. Compound models of all above considered solids can be built consisting of the model of the 9D cube and elements of a suitable set of the models of the lower dimensional parts. The new models also fill the space periodically.

The evolution of amusement parks’ spatial configuration mode in China from 1990s through space syntax analysis XIAOHUI, Chu; WENDA, Zhang; XIUXIU, Ji Marcel Breuer Doctoral School, Faculty of Engineering and Information Technology, University of Pécs

Keywords: space syntax, amusement park, space configuration With the amount of residential building construction or even high-rise is increasing. There is not enough outdoor amusement places for every normal family. Amusement park is playing an important character in modern city lives; in china is more serious situation. There are huge numbers of amusement parks in china. It is urging to provide much more high efficient amusement parks for rapidly growing resident population. Quantitative analysis compares spatial syntactic variables related to playground cases in different periods and interpreting of related parameters such as axial density, maze index and topological depth standard deviation, average integration, integration, standard deviation, synergy and intelligibility. Then analyzing the composition, shape and distribution of the integration core in the space system. The research results provide a more intuitive quantitative analysis platform and method for the amusement park research, quantitative analysis of the changes in the playground space configuration.

Comfort and energy performance analysis of a heritage residential building in Shanghai XIAOHUI, Chu; REZA, Ganjali Bonjar Mohammad; BARANYAI Bálint Marcel Breuer Doctoral School, Department of Energy Design

Keywords: heritage residential building, dynamic energy and climate simulation, thermal comfort performance Along with its rapid growth in the economy, the protection of heritage buildings has recently gained importance and awareness in China. This paper investigates the energy performance of a heritage building (Wang’s House) in Shanghai, as well as the thermal comfort of the users, using dynamic thermal simulations. The analysis showed that heating accounts as the highest energy demand, followed by cooling and lighting. The resulting study will help the authors to identify various sustainable strategies to improve users comfort as well as reduce the energy demand for heritage buildings in China.

Keywords: building extension, building simulations, shading, window-wall-ratio, thermal mass, thermal comfort, daylighting, used energy demand, sketch planning optimisation Within the framework of the Modern Cities Program, a building physics development was undertaken for the new block of the University of Pécs, Medical School. During sketch planning session climate, light and energy simulations were applied to quantify optimisation strategies. The planned building possesses approx. 12,000 m2 of useful floor space. The client’s needs determined the basic concept, space organization, building shape, structures and the installation of doors and windows must be considered as fixed boundary conditions. We tested in various simulation cases diverse shading possibilities, glazing ratios and the abandonment of suspended ceilings (release of internal heat storage masses) to evaluate the impact of illumination, radiation gains/loads, transmission and ventilation losses in visual and thermal comfort and in the used thermal energy demand. The goal was to select a building version with the most favourable thermal and visual comfort, coupled with maximum reduction of operating and investment costs. The most optimal model’s façade comprises windows without external shading, 90 cm high parapet and the suspended ceiling is abandoned from the interior ceilings. These modifications represent in the whole building a 9% cooling and 5% saving in used thermal energy. This variant was proposed for further developed during approval and construction design phases.

Traditional archery center – Pécs - downtown ZRENA Zoltán; KÓSA Balázs; BARANYAI, Bálint University of Pécs Faculty of Engineering and Information Technology

Keywords: traditional archery centre, downtown, Pécs Archery is a diverse traditional sport, which can be learned at a young age and instills a passion that can stay with us throughout our lives. In addition, archery is part history, our history. Even though it used to distance us from other peoples, it also provides a connection to them. Traditional archery is gaining more and more popularity in our country and in Europe as well, due to its spectacle, atmosphere and traditions. The site chosen by my thesis, is located on the border of the peaceful city center and the bustling downtown of Pécs. The dimensions of the property allow us the creation of archery ranges for both historical- and indoors archery. In addition, the building humbly fits in to the archaic architecture of its environment due to its design and traversability. The building would contain an archery store and rental place from the side of Rákóczi Street. The reception and changing rooms would be found on the side of Tímár Street. The two functional areas are connected via a hallway, which is also the location for an exhibition presenting the peoples and bows of Eurasia. Here one can compare and contrast the archery traditions and bow designs. The building also functions as an interactive museum, thereby it can be an addition to the cultural establishments of Pécs. The archery ranges can be found on the upper floor. The upper floor is also the location of a traditional tea house, along with an atrium, which brings a close intimacy with nature to the building. The Archery Center is an exciting, enclosed, statuesque mass with its fine surface plasticity, which almost levitates over the urban squares and gardens; like a fully drawn bow ready to shoot, or an arrow ready to be released.
