RES NEWS - Donations

Did you know…

YOU can donate stocks, mutual funds or other investments DIRECTLY to RES? WHY? As a 501(c)(3) charitable organizaon, gis to RES are considered charitable donaons and you can use this strategy to increase the value of your donaon while removing appreciated investments from your porolio.

By donating an investment directly, you can remove the full value of the investment from your portfolio without realizing any taxable gains.

An example: Suppose you want to donate $5,000 to RES. If you sell investments of that value, you might generate $500 in taxable gains. Tax on those gains would be due when you file your taxes the following year. However, if you donate securities, you can gift the full $5,000 without generating any taxable gains.

This strategy is a great way to achieve you charitable giing goals while making the most of your resources and having minimal impact on your “everyday” spending and cash flow.

RES is not a tax advisor. We encourage you to work with a tax professional to ensure this is an appropriate strategy for your goals.

HOW?

Contact your broker or financial advisor and for the necessary and informaon.

Are you interested in

Supporng The Rochester Engineering Society (RES) and

reducing your tax liability?

Are you rered and receiving Required Minimum Distribuons (RMD) from your rerement accounts?

If you answered yes to the above…

then Qualified Charitable Distribuons (QCD) might be a great way to reduce your tax liability and support the RES mission!

What is a Qualified Charitable Distribuon (QCD)?

A QCD allows you to make tax-free donaons directly from your tax-deferred rerement accounts to a charitable organizaon while reducing your RMD. Typically, you will receive an RMD and pay taxes on it. By using a QCD, you can make a dollar-for-dollar charitable gi without paying any taxes and reduce the amount of RMD remaining to be taxed.

To learn more about how using a QCD can help you and RES, please visit the website today! www.roceng.org.

RES - Technical Corner

Technical Corner - Electrical Engineering Focus The article this month will be Electrical focused with some related information regarding Generators.

It also doesn’t require a formula or a calculator. Happy New Year…!!

Apparently, there is somewhat of a small market for larger single-phase generators. Often, specifically in our business line, of commercial and industrial projects, we are almost always looking for a way to specify a 3-phase electrical service. With this, if we are seeking the need for a generator, it too will be a 3-phase model.

Many of you might own a single-phase generator for your residential home because your home is not a 3-phase service. Also, residential generators are generally a smaller kW rating and are portable.

The larger more stationary, whole house residential ones are say 10kW to 20kW depending on the manufacturer. Also, most homes just don’t draw that much power.

I couldn’t believe it when I saw a more stationary, big box, single-phase generator right up to the 150kW mark. I just don’t know how strong the market could be for this type of unit. I suppose that this is one that the manufacturers don’t have on the shelf waiting to be ordered. So, I suspect the lead time is tremendous for a “special unit” like this as the manufacturer has to actually build it.

Another interesting thing I found out is that some of the larger single-phase generators are equipped with 3 pole output circuit breakers. It clearly says on the front of the breaker “suitable for use on single phase AC circuits”. I’d think there would be a single-phase breaker installed instead but maybe it makes sense to have a 3 pole so it’s not another option a manufacturer needs to test or another product they have to have on the shelves. So, im thinking it’s a simplicity thing.

Some Reference Material: According to UL’s White Book, “3-pole circuit breakers are suitable for use on 3-phase systems only, unless marked to indicate use on 1-phase systems, such as, “For 1-phase connections, use two outside poles,” or an equivalent statement. A 3-pole breaker used in place of a 2-pole breaker on a 3-phase system, such as a 2-pole breaker used in a branch circuit that is actually two legs of a 3-phase system, is acceptable without the 3-pole breaker being specifically marked.”

Hopefully this article finds you well and can be used as a reference for your project needs.

If anyone would like to contribute to the RES magazine and add an article or would like to request information on a specific topic (not limited to Electrical) just email me at Brett.Eliasz@collierseng.com. As always, any comments are appreciated…! Thank you for reading.

STUDENT FEATURE - Up & Coming Engineer

Meet Another Young Engineer: Maureen Zhang

by Noah Kelly

For high school students, the conclusion of the school year doesn’t just mark the end of exams and homework; it signifies the start of summer break. Many students find themselves diving into this season with days full of beach escapades and video game marathons. However, for Maureen Zhang it signified the start of something much different. While her peers were busy planning summer trips and catching up on Netflix, Maureen opted to spend her vacation as an intern at a plasma physics laboratory. Here, she was inspired by the scientific environment and the enthusiasm of her peers. Through her time at the lab and learning about the first imaging from the James Webb Telescope, Maureen became very interested in the discovery of exoplanets.

Exoplanets are otherwise known as planets outside of our solar system. Organizations such as NASA primarily search for exoplanets to locate planetary environments similar to our own. Traditional methods of exoplanet detection are often times unreliable and can output false positives. The process for exoplanet detection is also quite tedious and can require astronomers to manually process light curves for potential planetary systems. In addition, the majority of currently available data has explored single planet systems, where each potential exoplanet must be individually checked and verified.

Figure 1. Artist's Impression of the Kepler-22 System and its Exoplanet

Maureen wanted to further explore the discovery of exoplanets. She was aware that there are many 12 | The ROCHESTER ENGINEER JANUARY 2024

res - up & coming engineer

exoplanets that are missed within multiplanetary systems. And by machine learning and NASA’s Exoplanet Archive, she had developed a methodology to explore multiplanetary systems and increase the speed of exoplanet detection.

This machine learning project was split into two parts to explore a variety of classification models. The first part compared machine learning models against NASA’s Exoplanet Archive. When optimizing these models, Maureen noticed a heavy bias towards single planetary systems. In the second part of this project, Maureen utilized clustering algorithms to identify hidden patterns in the reported data. Through this, Maureen gained insight on which reported single planet system could host additional exoplanets. With this implementation, Maureen saw a much higher accuracy of exoplanet detection which rivaled that of previous studies.

Maureen believes the next step to improve her detection method is to increase the sample size of exoplanetary data. She looks forward for the James Webb Telescope to add more data revolving around multiplanetary system to NASA’s database. She also believes with this additional data, she can further refine the parameters to her machine learning models to better classify exoplanets. Maureen plans to continue working on this project to optimize her methodology.

Maureen has cited her math teacher as an inspiration for becoming STEM oriented. Through the use of creative problem solving and a collaborative work environment, Figure 2. James Webb Space Telescope Mirror Seen in Full Bloom

Maureen was quickly drawn to mathematics. She then used this passion for mathematics and applied it to scientific endeavors outside of the classroom.

In the future, Maureen in looking to further pursue education in Physics and Astronomy. She is also very passionate about scientific outreach and accessible education opportunities for all. Maureen recommended anyone interested in STEM to identify what you are passionate about and pursue it no matter what. She stressed the importance of reaching out to mentors and your support system as you chase after your goal.

And most importantly she said “as you explore your opportunities, it is always important to give back to the community that helped you”. q

RES NEWS - ROCHESTER HISTORY A Sampling from the Archives of the Rochester Engineering Society.

1897 - 1977

by Lee M. Loomis Continuing with the historical sampling of the earlier writings on behalf of the Rochester Engineering Society, the years following "The Great War", into and through the “Great Depression”, continued to be a time of reaching out for the maturing Society, both locally and nationally. The meeting minutes describe a series of technical discussions and presentations intended to broaden the technical horizons of the membership (especially the CE's, ME's and EE's).

The RES affiliated itself with a number of National technical societies, adopted local Affiliated Societies, frequently held joint meetings with them and continued taking action on a growing list of public matters. Certain issues of standardization, some crucial to public safety, became the responsibility of the RES and its affiliates. In the pervasive economic downturn of the “Great Depression”, the magazine offered classified advertising for unemployed engineers, technicians and draftsmen and took other steps to try to deal with the crisis. Still, it continued its effort to shape the function, focus and infrastructure of the City of Rochester, and beyond. World War, again affected the Society, taking away many of its leaders while providing opportunities for others to step forward to fill these vacancies. In an effort to provide even greater perspective on the happenings and concerns of the day, a synopsis, featuring selected items from "The Rochester Engineer" has become an integral part of this series. The Second World War, the Korean Conflict, and the Vietnam War are now history. These experiences have changed the face of and will, no doubt, influence the future of the community. The Rochester municipal leadership and the industrial community have become immersed in the cold-war, growth economy.

September 14, 1977 (Board Meeting, University Club) The Board approved two

Regular Membership applications and one Student Membership application. J. Gary Parker, Chair of the Rochester Section of the American Society of Chemical Engineers, was introduced and gave a synopsis of his organization’s activities.

Earl Svendsen of the RES Luncheon Committee reported that speakers had been scheduled for the September, October and November luncheons. Carl Lundgren of Solar Utilization in Northwest New York (SUNNY) thanked the RES for its invitation to become an RES Affiliate. They meet regularly at RIT and have approximately 200 members. RES President John Robertson reported that he had met with magazine publisher, Peter Allen regarding recent, numerous typos in the Society’s magazine, and that he had been assured that the problem would be dealt with.

President Robertson also reported that a letter had been received from Gates Town Supervisor, Jack Hart, requesting RES assistance with interpreting a recent Monroe County Airport Noise Control Study. After some discussion, the matter was referred to the RES Civic Affairs Committee for possible RES “Skills Bank” support. In response to a request from the Center for Environmental Information for RES assistance in fund raising for their organization, the Board decided that the RES should NOT take part in funding solicitation for ANY group.

“The Rochester Engineer” (September 1977) This issue announced that Solar Utilization in Northwest New York (SUNNY) had become the 30th RES Affiliate organization. RES Senior Past President, John F. (Jack ) Schickler, Plant Manager, Assembly, Rochester Products

res news - history

Division (RPD), General Motors Corp., provided an article describing the reasons for GM’s decision to expand RPD in Rochester, NY. Specifically, the new production facility, on 54 acres at 500 Lee Road in the Rochester/Outer Loop Industrial Park, would be used for the assembly of emission control products and cigarette lighters. With insufficient space at 100 Lexington Avenue for this 278,00 square-foot facility, a new location was sought. Jack reported that there had been three positive factors for this expansion happening in Rochester, rather than elsewhere. These included, GM’s existing production situation, the technology involved in GM’s products, and the existing support systems in the Rochester Community. Jack stressed the importance of short lines of communication to enable quick reaction to market changes as essential to GM’s continued production successes. An article reprinted from “Greater Rochester Commerce” describes the scene of a strangely-clothed character, reaching into his belt to remove an object no larger than a pack of cigarettes, into which he speaks, “Spock to Enterprise – Come in please”. In this article, William Gruenwald, VP of Marketing for Harris/ RF, announces that his company is uniquely positioned to achieve the ultimate in personal communication. He stated, “Some day you will be able to buy Spock’s Communicator, a Harris/ RF Communicator, built on University Avenue in Rochester, NY. In his Legislative Watchdog column, Andy Hirsch, RES Technology Agent, County of Monroe, City of Rochester, shared his impressions of local situations as he traveled in several cities, towns and rural communities meeting the responsibilities of his unique job under contract to the National Science Foundation (NSF).

Editor’s note: Andy’s innate sensitivity to the people and situations he encountered made him an excellent choice for “Technology Agent” in the RES Technology Transfer Program.

October 12, 1977 (Board Meeting, University Club) The Board approved three

applications for Regular Membership and one application for Sustaining Membership. Reporting for the Membership Committee, RES Executive res news - history

Director Joseph Campbell announced that RES membership stood at 599. President John Robertson reported that he and Joe Campbell had met with Peter Allen, the magazine publisher, and they had agreed that, going forward, the magazine could be provided to members of RES Affiliate societies for $.10 per issue, or $1.10 per year.

“The Rochester Engineer” (October 1977)

In his monthly report on the Technology Transfer Program, Technology Agent, Andrew Hirsch reported completion of three Technology Transfer Projects, including a study of the Midtown Parking Garage, a recommendation to use “mixed” road salt (ie. NaCl & sand) for highway winter salting and methods of preventing the unauthorized opening of fire hydrants on the hotter days of summer. He also reported that a technical needs assessment for the Departments of Public Works (both County & City) were nearing completion.

Under development were an energy management project for County & City buildings, guidelines for parks and playgrounds for improved handicapped access, and the Pure Waters Consolidation Study Group. Andy also announced that the RES had received approval of the second funding award of $40,000 bringing the total funding to have been allocated for this NSF sponsored program to $55,000 as it reached the end of its first year in operation.

Subsequent articles in this series will describe the RES' continuing outreach to other technical societies as it considered its role in this and the larger community, along with more of the activities of the RES as it moved to be of greater service to its membership, especially those suffering from current economic crises, and adopted a greater role in shaping the future of the City and its environs. Noted also, will be the contributions made by RES members in the struggle to meet the challenges coming out of World War II and the Korean Conflict, as well as a hoped-for period of post-war growth and prosperity. These articles will also feature an impressive array of RES activities in support of post-war re-emergence of Rochester area industry, and the continuing prosperity of the second-half of the 20th Century.

We welcome your questions and comments on this series.

Get IT Done

Technical Support Strategies for a Smooth Holiday Season (in the rearview mirror)...

The holiday season brings joy and festivities, but it can also present unique challenges for technical support teams. With many staff taking off, it’s often an opportunity to do critical maintenance tasks. To ensure a seamless staff experience during this busy period, support teams need to implement effective support strategies. In this article, I’ll explore key tips and strategies for technical support teams to handle the balance of proactive maintenance, staff vacations and minimizing frustration.

Staffing and Resource Planning: The first step in preparing for the holiday rush is to assess staffing requirements. Analyze historical data to identify peak periods and allocate resources accordingly. Consider hiring temporary staff or extending working hours to accommodate increased support requests.

Straining memory leads to new computing possibilities Researchers develop hybrid phase-change memristors that offer fast, low power, high-density computing memory By strategically straining materials that are as thin as a single layer of atoms, University of Rochester scientists have developed a new form of computing memory that is at once fast, dense, and low-power. The researchers outline their new hybrid resistive switches in a study published in Nature Electronics.

Developed in the lab of Stephen M. Wu, an assistant professor of electrical and computer engineering and of physics, the approach marries the best qualities of two existing forms of resistive switches used for memory: memristors and phasechange materials. Both forms have been explored for their advantages over today’s most prevalent forms of memory, including dynamic random access memory (DRAM) and flash memory, but have their drawbacks.

Artist’s rendering of a 2D material strategically strained to lie precariously between two different crystal phases. Stephen Wu, assistant professor of electrical and computer engineering and of physics, is using such materials to create hybrid phase-change memristors that offer fast, low-power, and high-density computing memory. (University of Rochester illustration / Michael Osadciw)

Wu says that memristors, which operate by applying voltage to a thin filament between two electrodes, tend to suffer from a relative lack of reliability compared to other forms of memory. Meanwhile, phase-change materials, which involve selectively melting a material into either an amorphous state or a crystalline state, require too much power.

“We’ve combined the idea of a memristor and a phase-change device in a way that can go beyond the limitations of either device,” says Wu. “We’re making a two-terminal memristor device, which drives one type of crystal to another type of crystal phase. Those two crystal phases have different resistance that you can then story as memory.”

The key is leveraging 2D materials that can be strained to the point where they lie precariously between two different crystal phases and can be nudged in either direction with relatively little power.

“We engineered it by essentially just stretching the material in one direction and compressing it in another,” says Wu. “By doing that, you enhance the performance by orders of magnitude. I see a path where this could end up in home computers as a form of memory that’s ultra-fast and ultra-efficient. That could have big implications for computing in general.”

Wu and his team of graduate students conducted the experimental work and partnered with researchers from Rochester’s Department of Mechanical Engineering, including assistant professors Hesam Askari and Sobhit Singh, to identify where and how to strain the material. According to Wu, the biggest hurdle remaining to making the phase-change memristors is continuing to improve their overall reliability—but he is nonetheless encouraged by the team’s progress to date. q campus news

Banning Refrigerants 134a and 410a in New York State & Exploring Alternatives with Heat Pump Water Heaters

by Megan Eaton

Introduction New York State (NYS) is known for its commitment to sustainability and environmental conservation. In line with its ambitious climate goals, NYS has taken a significant step towards reducing greenhouse gas emissions by disallowing the sale of equipment using refrigerants like 134a and 410a in 2024. This move not only aligns with the state's dedication to combating climate change but also presents an opportunity to explore alternative refrigerants, particularly in the context of heat pump water heaters.

Visual History of Refrigerants

Banning High-GWP Refrigerants in NYS The decision to ban refrigerants like R-134a and R-410a in NYS is rooted in the need to reduce the state's carbon footprint and curb the release of potent greenhouse gases into the atmosphere. These refrigerants have high GWP values, meaning they trap heat in the atmosphere and contribute to global warming when they leak or are not properly disposed of.

NYS has recognized the importance of addressing these refrigerants' environmental impacts and has implemented regulations to phase them out starting January 1, 2024. This includes restrictions on the use of these refrigerants in new equipment and the promotion of more environmentally friendly alternatives.

How Does This Affect Mechanical Engineers?

While continuing education is nothing new to professional engineers, mechanical engineers – more than ever – need to stay up-to-date on the latest regulations and developments as they relate to new-build and renovation projects. They should familiarize themselves with the properties, handling procedures, and equipment compatibility of alternative refrigerants that comply with the new regulations, for instance. Some new refrigerants can be considered flammable and other design considerations may need to be taken into account when bringing refrigeration lines into buildings. Additionally, since different refrigerants have varying energy efficiency characteristics, mechanical engineers may need to optimize system designs to maintain or enhance energy efficiency while complying with the new regulations. There will be cost implications, as well. Lots to consider with these new regulations!

Heat Pump Water Heaters and Alternative Refrigerants Heat pump water heaters, which are an excellent example of cleaner and more efficient technologies, use refrigerants to transfer heat from the air or ground into the water. This makes them a highly efficient and energysaving option for water heating.

As NYS moves away from high-GWP refrigerants, however, it is crucial to consider alternative refrigerants for heat pump water heaters. Here are some viable options: • R-32: R-32 is a low-GWP refrigerant that has gained popularity as an alternative to R-410a. It has a GWP

approximately one-third that of R-410a, making it a more environmentally friendly choice. Many

manufacturers are already using R-32 in their heat pump water heater systems.

• Hydrofluoroolefins (HFOs): HFOs are a new class of refrigerants designed to have low GWP values.

Variants like R-1234yf and R-1234ze have been developed as replacements for high-GWP refrigerants in

various applications, including heat pump water heaters.

• Ammonia (NH3): Ammonia is another natural refrigerant with zero GWP and excellent thermodynamic

properties. Although less common in residential applications, ammonia-based heat pump water heaters are

highly efficient and environmentally friendly.

• CO2 (Carbon Dioxide): Carbon dioxide (CO2) is a natural refrigerant with zero ozone depletion potential

and a GWP of 1. CO2 heat pump water heaters are highly efficient and have minimal environmental impact.

They are gaining traction as a sustainable choice in NYS and beyond.

Along these lines, RP Fedder – a local distributor of HVAC and air filtration equipment – now offers the Aegis CO2 Heat Pump Hot Water Heater, which utilizes R744 – carbon dioxide – as a refrigerant.

The Environmental Sustainability of R744 •

Low Global Warming Potential (GWP): One of the most compelling aspects of R744 is its incredibly low GWP value of 1. This means that when CO2 is released into the atmosphere, it has a minimal impact on global warming. In contrast, many traditional refrigerants, such as hydrofluorocarbons (HFCs), have GWPs in the thousands. R744 is the reference gas for GWP so it is considered future-proof. In contrast, the soon-to-be-phased-out refrigerants R-410a and R-134a, have GWPs of 2,088, 1,430, respectively!

•

Zero Ozone Depletion Potential (ODP): R744 does not deplete the ozone layer, making it an environmentally friendly choice. This stands in stark contrast to older refrigerants like chlorofluorocarbons (CFCs) and some hydrochlorofluorocarbons (HCFCs) that have been phased out due to their ozonedepleting properties.

•

Natural and Abundant: CO2 is a natural refrigerant that is abundantly available. It is a byproduct of various industrial processes and can be sourced sustainably. This reduces the reliance on synthetic and potentially harmful refrigerants.

The Safety and Energy Efficiency of R744 •

Non-Flammable: R744 is non-flammable, making it a safe choice for refrigeration systems. Unlike some other refrigerants that can pose fire hazards, CO2 enhances safety.

•

High Energy Efficiency: CO2-based refrigeration systems, particularly transcritical systems, can achieve high levels of energy efficiency. These systems are widely used in supermarkets, industrial refrigeration, and heat pump applications. Their efficiency helps reduce energy consumption and operating costs.

•

Efficient Heat Pump Applications: R744 is increasingly used in heat pump systems, where it efficiently captures and transfers heat from one location to another. This is particularly important in heating and cooling applications, contributing to reduced energy consumption and carbon emissions.

Challenges and Considerations of R744 While R744 is a highly sustainable refrigerant, it's not without challenges. One of the biggest considerations that your clients may be concerned with involves upfront costs. The initial investment in CO2-based systems may be higher than other systems, but the long-term energy savings and sustainability benefits more than justify these costs.

All that said, R744, or carbon dioxide, is a shining 24 | The ROCHESTER ENGINEER JANUARY 2024

RIT Students Building Device To Keep Astronauts Healthy in Space Project widens the orbit of a collaborative team that includes engineering, game design, and exercise science students Students, faculty, and alumni at Rochester Institute of Technology are participating in NASA’s national Moon to Mars initiative to build a training device and monitoring tool to help make extended space travel healthier for astronauts.

The project, led by mechanical engineering Associate Professor Kathleen Lamkin-Kennard, is being funded by NASA through its National Space Grant Foundation. Integrating game Kathleen Lamkindesign, exercise science, and Kennard. Credit: RIT wearable technology, this Photography is the second NASA design project that RIT students were selected to participate in that combines the strengths of the university’s technology, arts, and engineering programs.

NASA’s Perseverance Mars Rover explores the planet on various scientific missions. RIT students are part of collegiate design challenge to build equipment that will support astronauts as they spend more time in space, and possibly on the Red Planet in the future. Credit: NASA/JPL – CalTech/MSSS images

The goal is to focus more on the Mission to Mars where astronauts are expected to be in space for longer time periods. Student teams are being asked to design technology devices or systems that will assess physiological signals from the astronaut at rest and when they are engaged in physical activity.

Each year, NASA coordinates a collegiate design challenge. Its engineering project managers partner with student teams selected from across the country, providing project guidance throughout the development process.

“They need to have some type of demonstration of the technology,” said Lamkin-Kennard, a faculty-researcher in RIT’s Kate Gleason College of Engineering. “There are different types of requirements during the NASA projects because you are dealing with things in space, in zero gravity, altered gravity and how do you deal with this? The students get to look at real-world things for real-world customers, so it puts a little more pressure on them. When you know you have a meeting with NASA, I think it can get a little intense for them.”

Sarah Manes, project lead for the student team, agreed. “NASA put forward this challenge to help combat muscle degradation in space while keeping the exercise fun and engaging for astronauts. Making this device autonomous and with a virtual reality element is what will make us stand out from other devices currently being used. Building a product to be used in space brings a whole new set of challenges and requirements that we’ve never encountered before. This pushes us to think of innovative ways to complete tasks that are straightforward on Earth. It’s quite exciting that we get to be the pioneers in this unexplored sector of space physiology.”

According to NASA, muscle mass and bone density changes take place due to limited or no gravity.

“I was inspired while walking through Imagine RIT last year to try to propose a senior design project that combines my interests in space and biomedical devices. I stumbled upon last year’s XHAB team, and I knew that the NASA Challenge would be the perfect avenue to do this,” said Manes, a fifth-year mechanical engineering student from Mentor, Ohio.

Students building an astronaut training device are (front, left to right) Chris She enjoys rock climbing and saw the NASA Baron, Sarah Manes, Maiah Fallone and Angelo Besho. (Back row, left to right) Alex Speyer, Jennifer Indovina (project guide), Isken Mambetkadyrov, Matt challenge as an opportunity to devise similar Buck and Spencer Davis. Photo provided activities for the project. She worked with Lamkin-Kennard and mechanical engineering classmate Alex Speyer to propose an American Ninja Warrior-type of training device that was accepted by the agency and incorporated into RIT’s senior design program this fall.

Multidisciplinary Senior Design (MSD) projects are two-semester engineering courses where students develop project plans and build working prototypes for clients. Students work with professional advisers, called guides, who are often faculty members and alumni. This year, as in previous NASA project work, alumna Jennifer Indovina ’06 (electrical engineering), ’07 (MBA) has assisted with project development. Also involved are Beth DeBartolo, MSD director; David Schwartz, director of the School of Interactive Games and Media in RIT’s Golisano College of Computing and Information Sciences; and Bryce Beamer, research faculty in RIT’s College of Art and Design, and an expert in wearable technologies.

NASA’s objectives are to show how its major agency projects are developed, the role multidisciplinary teams play in the overall process, and how collegiate teams can contribute ideas and prototypes for future space missions.

The process aligns well with the engineering senior design program, said Lamkin-Kennard.

“What has been nice about both projects that we’ve had is they are part of this xHAB program, and the goal is really to engage students in design projects that follow NASA design processes. They want to bring students into that fold, and fortunately for us, it works really well with our senior design structure because they are very similar.”

RIT’s relationship with the Moon to Mars program began in 2021 when Lamkin-Kennard received the original NASA grant for the overall project. It also won honors in 2022 at the Imagine RIT: Creativity and Innovation Festival. In March 2023, the team was invited to Johnson Space Center in Houston to demonstrate the balance system to NASA engineers. The team received a New York State Space Grant Award in October to continue work on this project.

Undergraduate student team members are: Billy Guzik, game design; Alex Speyer, mechanical engineering; Spencer Davis and Iskender Mambetkadyrov, both biomedical engineering; Angelo Besho, computer engineering; Matthew Buck, electrical engineering; Chris Baron, industrial design, and Maiah Fallone, industrial and systems engineering. q campus news

Campus News - RIT RIT researchers develop new technique to study how cancer cells move In tumors, cells follow microscopic fibers, comparable to following roads through a city.

Researchers at the Rochester Institute of Technology developed a new technique to study different features of these “fiber highways” to provide new insights into how cells move efficiently through the tumor environment.

The study, published in the journal Advanced Functional Materials, focused on contact guidance, a process where migrating cells follow aligned collagen fibers. Understanding this process is crucial, as it plays a key role in cancer metastasis, the spread of cancer to other parts of the body.

Message from the 2024-2026 Chair, Kelly Robinson

Dear Colleagues, Happy New Year!

I am honored to begin my tenure as IEEE Rochester Section Chair. I thank Dr. Eric Brown, our Chair for the last four years, for his fine leadership!

Please allow me to briefly introduce myself. I have been part of the Rochester technical community for more than 40 years, beginning my 25-year career at the Eastman Kodak Company and 15 years with Electrostatic Answers as an engineering consultant for manufacturing companies. I have experienced the very high levels of scientific and engineering practice in Western New York and specifically in the Rochester area. I am excited by the opportunities to serve this vibrant technical community, help celebrate our accomplishments, and work to enable future progress and innovation.

Our IEEE Rochester Section Executive Committee (ExCom) meets monthly to plan events. Our next ExCom meeting will be on Tuesday, February 6th from noon to 1 pm.

Finger Lakes Chapter of INTERNATIONAL COUNCIL ON SYSTEMS ENGINEERING

January 2024 Chapter Meeting  Mini Presentation: Automotive Working Group (AWG) o Presented by Gary Rushton, AWG Co-chair.  The Automotive Working Group Mission:

To promote the application and advance the practice of Systems Engineering in the automotive industry, encompassing OEMs, suppliers, and service providers in the private, commercial, and industrial vehicle sectors. Emphasis is put on the current needs and future challenges of the industry, covering issues related to product development, complexity, safety and security, diversity, reuse, etc.



 Agile Systems Engineering … It’s Not Your Father’s Oldsmobile

o Presented by Rick Dove, who chairs the INCOSE working groups for Agile Systems and Systems Engineering, and for Systems Security Engineering

Abstract: The Manifesto for Agile Software Development and related processes like Scrum are well known, and well suited to software engineering. But software engineering is very different than electronic engineering, mechanical engineering, and systems engineering. Engineering today needs the agility to anticipate and effectively respond to increasingly dynamic and uncertain environments. While tactical methods (the how part) for engineering agility necessarily vary among different engineering domains, strategies (the what and why parts) for achieving these common goals are domain independent. Research has shown us fundamental common strategies that enable agility in any domain; but each domain needs to express these patterns differently to fit the nature of that domain. This presentation will profile eight strategic aspects with application examples practiced at Tesla and SpaceX. In June of this year (2023), the Requirement Working Group released version 4 of the INCOSE Guide to Writing Requirements. The latest version of the Guide to Writing Requirements (GtWR) is now in the INCOSE Store as well as an update to the 7-page GtWR Summary Sheet. The practice of systems engineering is evolving and so must the definition and management of needs and requirements. This new update represents this evolution in how we view needs and requirements across the lifecycle. During this presentation, Lou will provide an overview of the updated GtWR and the changes that we made along with a brief overview of the other RWG products including the Needs and Requirements Manual (NRM), Guide to Needs and Requirements GtNR), Guide to Verification and Validation (GtVV), and newly released version 4 of the Guide to Writing Requirements (GtWR) and how they relate to each other, the INCOSE SE HB v5, and the SEBOK.

This meeting will be on Thursday, Jan 18, 6 – 7:30 pm (eastern).

Attendees can attend via zoom or, if a US Person, in-person at L3Harris Technologies Rochester, NY (1680 University Avenue, Rochester NY, 14610).

Dear ASHRAE Family, At our December chapter meeting we were honored with an appearance from Dr. William Bahnfleth, ASHRAE Distinguished Lecturer and Professor of Architectural Engineering at Penn State University. Dr. Bahnfleth spoke about the new ASHRAE Standard 241: Control of Infectious Aerosols. This standard originated out of the COVID-19 pandemic and provides guidance on effective mitigation of infectious aerosols for various applications.

While the standard does not advocate for the use of specific technologies, it defines the term “Equivalent Clean Airflow” for an air filter. Equivalent Clean Airflow provides a framework within which we can supplement Outside Air requirements to mitigate operating cost increases while maintaining a healthy indoor environment. Over 95 people registered for our chapter meeting this month, a new high for the year! Thank you to all who attended and thank you to Dr. Bahnfleth for taking the time out of his busy schedule to present to our chapter.

We suspected that alignment gradients could efficiently direct cell movement but lacked the technology to test the hypothesis.”

endothelial cells moved faster and for longer periods of time along the direction of increasing alignment.

Breast cancer cell aggregates showed biased migration on graded alignment compared to uniform alignment. These results indicate that cells may respond to alignment gradients more effectively than conventionally studied contact guidance.

To bridge this gap, the RIT team developed a new microfluidic technique to create 3D collagen gels with tunable, tumor-like alignment gradients. These gels served as realistic miniature versions of the tumor environment and allowed the team to observe how endothelial cells and aggressive breast cancer cells responded to varying fiber patterns.

“This work suggests alignment gradients may play a role in guiding cancer cell movement and offers insights into how cells may navigate efficiently through the tumor microenvironment toward blood vessels,” said Abhyankar, who leads the Biomedical Microsystems Research Lab.

Results indicated that the
