Can hi-tech helmets reduce football head injuries?

BOSTON - As Americans grow more aware of the risk of brain injury tied to football — the country’s most popular sport — players and coaches are experimenting with the latest technology in a bid to make the game safer. Advances in training have led to bigger, faster players who have made the high-impact sport more dangerous, particularly at the college and professional level….

As America grays, businesses help seniors age in place

By Olga Khazan Eileen Morrissey has always been independent. But at 91, she can no longer drive, which has made it hard for her to get to the grocery store. At least once a week, she calls SilverRide, a San Francisco transportation service that takes elderly clients on errands of their choosing. “When I went to do my Christmas shopping, they carried my packages to the car,” Morrissey said. “They’re easy to talk to and they keep you in conversation.” Morrissey is among those seniors who are eschewing nursing homes in favor of independent living. … At-home devices for

seniors have come a long way since Life Alert, the classic emergency-response system with its token tag line, “I’ve fallen, and I can’t get up!” Although fall prevention is still a big part of the senior market — tumbles are a leading cause of injury among older Americans — the newest devices are more discreet. Researchers at Virginia Tech and the University of Virginia are developing a fallprevention device that can be worn as a piece of jewelry. It measures changes in gait or stability over time. “If a person decreases their walking velocity or is more prone to instability, we can use that information to identify health conditions

East Coast quake a ‘teachable moment’ By Chuck Raasch Six months after an earthquake shook the East Coast, its lessons still reverberate through the emergency management, engineering and geological communities. The magnitude-5.8 quake, centered in the tiny town of Mineral, Va., demonstrated that earthquakes aren’t just a West Coast threat. Big quakes had hit the East Coast before but not recently nor with the frequency or ferocity of those in California.

Game-changers off the playing field By Kevin Van Valkenburg The people who just might be able to save the sport of football from its own self-destructive ways don’t wear whistles or hold clipboards. They don’t file lawsuits, and they don’t dole out suspensions for helmet-to-helmet hits. Instead, they tend to wear lab coats. They might spend their days poking and prodding mice, interviewing patients involved in a study, or gathering data and obsessing over it. Some of them are men, and others are women. Some of them follow football closely, while others couldn’t tell you the difference between Peyton Manning and Peyton Hillis. The Hit System Typically, though, they have a few things in common: They try to focus on facts, not emotion, when it comes to a debate about head injuries in football. And they tend to work at a research university. … In recent years, athletic departments have been increasingly willing to open their doors to the research departments on campus, hoping to find the right balance between prevention and properly diagnosing head injuries. Take Virginia Tech, for example. In 25 seasons under coach Frank Beamer, the Hokies have built one of the best football programs in the country. But the school’s highly regarded Department of Biomedical Engineering might go down in history as having made a more important contribution to the game. Since 2003, thanks to engineering professor and department head Stefan Duma, all Virginia Tech football players have been outfitted with sensors in their helmets that can measure the number of the collisions they are involved in during the course of a football game, as well as the severity of them. It’s technology that was originally designed for soldiers in the military, but Duma immediately recognized the potential benefits for football players as well, and made his pitch to the athletic department. “Coach Beamer was very receptive,” Duma said. “He was not a hard sell at all. I think it helps that we had such a successful and longterm coach behind us, because there is obviously a lot of stress over this issue.” The data is collected by the sensors, and then uploaded in real time to a computer on the sideline where it can trigger an alert, warning the team’s medical staff any time a player is involved in a major collision. The Hokies don’t pull players from the game based solely on the sensor’s readings, Duma says, but it does help them immediately look for signs of a concussion. Schools like North Carolina, Oklahoma, Dartmouth and Brown have already implemented the system, which costs between $50,000 and $75,000, and Duma said several

NFL teams have shown interest. “We know every single head impact that has happened to all of our football players in the last 10 years,” Duma said. “We know the exact exposure. We know how many times they’ve been hit, how hard, and what direction the hit came from. That’s much more powerful than talking about hits without knowing how many actual exposures there were, because exposure is the key. It’s like cigarettes. It doesn’t matter how packs of cigarettes are in your pocket, it matters how many you smoke.” The research data, as well as 2,000 crash tests done in the department’s 25,000-square-foot lab in Blacksburg, Va., also helped the school come up with a five-star rating system for all football helmets sold in the United States. The ratings,

the first of their kind, were so influential, according to Duma, the lowest-rated helmets -the Riddell VSR-4 and the Adams A2000 -- were taken off the market by their manufacturers. “When we switched from the VSR-4s to the Riddell Revolution, it was like a light switch,” Duma said. “Concussions were reduced by [more than] 31 percent.” Virginia Tech isn’t the only major program welcoming scientists into their locker room to study brain trauma. For the second straight year, Stanford football players will be wearing mouth guards that have tiny sensors implanted in them to measure the severity and frequency of hits they endure. The data is collected, stored and then studied in a hundred different ways by budding young scientists. …

Pop Warner Weighing Research and Risks in Concussion Prevention Efforts

By Tim Rohan The unremarkable football career of Dr. Julian Bailes, who is now the chairman of the Pop Warner medical advisory board, ended quietly during his college days in the 1970s. He never sustained a concussion that he knew of, but he can recall a friend in high school who did. Confused and concussed, his friend started describing a car he had just bought; there was no new car, and Bailes found it hilarious. “We didn’t know any better,” he said. Now, his son is a 13-year-old football player who understands the risks, Bailes said, and still wants to play, so Bailes allows him to. For now, assuming the risk is Bailes’s choice, and his son’s. But the future of youth football may be determined by research that continues to redefine what the sport considers safe. On Wednesday, in an attempt to limit head injuries to young players, Pop Warner issued new rules that put restrictions on the amount of contact players can have

in practice. … Stefan Duma, the head of the biomedical engineering department at Virginia Tech, oversaw the research published in February that prompted Pop Warner to issue its rules changes. The study, the first of its kind for participants that young, placed sensors in the helmets of seven youth football players ages 6 to 8 during their 2011 season. Calling it a pilot, Duma expected the impacts to be too inconsequential to record. Results showed that about 95 percent of the impacts were between 15 and 20 g’s — what Duma likened to an “aggressive pillow fight.” The other 5 percent spiked to 50 to 100 g’s — what Duma characterized as a “car accident.” Duma noted that collegiate and professional football players had a low risk for concussions at 100 g’s. But research has shown that the damage from concussions can be cumulative, and that the brains of younger athletes may be particularly susceptible. So Pop Warner tried to lessen the num-

ber of impacts by reducing incidents in practice, when a majority of the “car accidents” took place, according to Duma. This fall, Duma will participate in a joint research project with Virginia Tech and Wake Forest that will more thoroughly evaluate six teams, about 300 players ages 6 to 13, as a follow-up to better understand the pilot project. Research has been difficult to quantify, Duma said, because “no one knows how many times or how hard players have been hit.” Until recently, it was common to hide or minimize concussions. “There has to be scientific data that makes that decision,” he said about making changes in football. “It can’t be a group of people telling stories of how they used to play football. You’ve got to actually quantify what drills are causing what level head impact, and target those, and minimize those.” … (Editor’s Note: This article also appeared on WSKG Radio, Public Broadcasting Service (PBS), and WXXY-FM.

Va. Tech at the forefront of football helmet safety By Mike Barber BLACKSBURG — Being protected by state-of-the-art equipment — from shoulder pads to helmets — can be empowering for college football players. With the right gear, “you just go out there and play ball,” Virginia Tech sophomore safety Kyshoen Jarrett said. “I guess the safety of the helmets and stuff like that helps us not worry as much.” Jarrett may not be thinking about concussions while he’s playing and practicing, but Vir-

ginia Tech’s training staff certainly is. During each Hokie game or practice session, about 25 players wear helmets outfitted with sensors to measure the impact of hits to their heads. It’s all part of the research of Dr. Stefan Duma, the department head of the Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences, who last year released the first independent ratings for football helmets. Duma’s study put each helmet through 120 impacts at

varying forces and spots. The amount of head acceleration was measured and recorded, and the helmets that did the best job of reducing acceleration received the highest ratings. The idea for the ratings system came from a question posed to Duma by the Tech football program. “Several years ago, they asked us, ‘Hey, what helmets should we buy?’ “ he recalled. “There was no data out there to grade helmets.” Duma said there are two

main factors that affect how well a helmet protects. The first is the design of the outer shell, and the second is the use of padding inside the helmet. His study gave three helmets the highest possible rating of five stars: the Riddell Revolution Speed, the Rawlings Quantum Plus and the Riddell 360….

NASA’s push toward carbon-neutral airliners By Guy Norris To achieve sustainable growth in air travel, future airliner designers face challenges never seen by their predecessors. New concepts will not only have to meet unprecedented performance goals, but they must do so while striving for carbon neutrality. NASA’s goal to solve this conundrum takes on new significance in coming weeks as researchers across the U.S. begin a series of landmark tests under the next stage of the agency’s subsonic fixedwing program. Wide-ranging work will include refining a glider-like truss-braced wing and integrating it with a hybrid-electric propulsion system, wind tunnel

RATINGS - IEEE SPECTRUM -

Just one day before Seau’s death, researchers at Virginia Tech released their second annual report rating the effectiveness of football helmets in reducing the likelihood that a player will exhibit signs of a concussion at some point during a season. The Riddell Revolution Speed, the only helmet to earn the highest rating of five stars last year, was joined atop the rankings by two new models: Riddell’s 360 helmet, and the Rawlings Quantum Plus. Two other new Rawlings models — the Impulse and the Quantum — received four stars. Overall, says the Virginia Tech team, seven helmet models earned four stars; five others — like the Xenith X2, which was introduced after the Virginia Tech helmet ratings were released last year — earned three stars or less. The makers of the models rated two stars and below have immediate cause for concern. “The three lowest rated helmets from last year are now all off the market,” says Steven Rowson, assistant professor of biomedical engineer-

ing at Virginia Tech. “It is encouraging to see this positive shift towards better head protection.”… Virginia Tech’s STAR (or Summation of Tests for the Analysis of Risk) Evaluation System was developed using a mountain of data in a national database comprising over 1.8 million head impacts collected over eight years with the cooperation of college players whose helmets were retrofitted with the HIT system. Now the researchers can simply drop helmets from a given height and strike them with foreign objects to assess the likelihood that players wearing them will suffer a concussion over the course of a season. But what they know relates specifically to adult helmets. The next order of business for the group is extending their research to the helmets worn by youth football players. It’s an important step, because of the possibility that mild brain injuries have begun to accumulate even before a player reaches the high school ranks. …

Ross garners CAREER award to advance understanding of fluid flows

In engineering, a dynamical system has a multitude of meanings. Fluid flow in the human body is considered to be such a system, as well as pollution and pathogens that travel through the air. In fact, atmospheric and aquatic environments provide a dynamical system for a plethora of biological activities. Even the motions of a basketball team or the shuffle of dollars through the economy constitute a dynamical system. For the past eight years, since receiving his Ph.D. from the California Institute of Technology, Shane Ross, now an assistant professor of engineering science and mechanics at Virginia Tech, has focused his career on determining these various types of behavior and how to more successfully predict what many once believed to simply be chaotic motion.

A Hard Hitting Story:

Young Football Players Take Big-League Hits To Head

(Transcript) JUDY WOODRUFF: Now, little kids and the danger of hard hits in youth football. There’s been growing awareness of the risks of head injury for those who play football at the high school and higher -- particularly at the professional level. But new research shows that young children may be knocking each other down with more force than many realize. Special correspondent Stone Phillips has the story. STONE PHILLIPS:

Growing concern about head injury in America’s favorite sport have focused a lot of attention on professional, college and high school football. But what about the estimated 3.5 million kids playing below the high school level? How much are they exposed to? How hard are they hitting? It’s easy to assume collisions involving the games’ youngest players aren’t that powerful. But last fall, a top researcher at Virginia Tech teamed up with a volunteer coach for the first study ever conducted

of head impacts in youth football. The results, reported here for the first time -information parents need to know. These 7- and 8-year-old boys played football for the Auburn Eagles, a recleague team in Montgomery County, Va. They’re watching highlights from a memorable season. Memorable, because last fall their team took part in a groundbreaking study -the first of its kind on head impact in youth football, which accounts for 70 percent of those playing tackle

football in this country.  STEFAN DUMA, professor, Virginia Tech: If you look at the NFL you’re talking about 2,000 players, college 100,000, 1.3 million in high school, but 3.5 million youth 6- to 13-year olds. We know a lot about the adult. We don’t know much at all about this youth population. STONE PHILLIPS: Stefan Duma conducted the study. He’s a professor of Biomedical Engineering at Virginia Tech and a leading researcher in the field of injury biomechanics. The

testing he does is aimed at engineering better, safer designs for the auto industry, the military, even toy companies learning about the limits of human tolerance for impact, and injury. For years, Duma has also been focused on football helmets and player safety. His youth study with the Auburn Eagles began by providing the team with new helmets, seven of them outfitted with sensors to measure hits to the head. The technology isn’t new but applying it to kids as young as 7 and 8, is….

NFL Commissioner Roger Goodell took an opportunity Wednesday to take the issue directly to where many believe it is needed most: kids. After watching a group of youth football players in northern Virginia go through safe tackling drills, Goodell preached the message that good health takes precedence over being a tough guy….

Monitoring kids Stefan Duma, department head of biomedical engineering at Virginia Tech, found in a study last fall that some of the hits absorbed by youth football players equate to those seen in major college football. Duma, who has been using a sensor system placed in the helmets of Virginia Tech football players for the past decade, used the same system on 7- and 8-year-old tackle football players in Virginia. The sensors record G-force - the gravitational force associated with the acceleration of an object relative to a free-fall. According to Duma, the typical hit for Virginia Tech players is about 20 Gs, and any hit above 98 Gs is cause to check the player for a concussion. Among the youth players he monitored last fall, the strongest hit was measured at 100 Gs, with six

Innovative Sensor to Stop Falls

By Lindsey Getz Recent data suggest that fall accidents are on the rise among the older adult population. In fact, according to the Centers for Disease Control and Prevention (CDC), each year one in three adults aged 65 and older experiences a fall. Falls are now the leading cause of injury-related deaths among this population and the most common cause of nonfatal injuries and hospital admissions for trauma. However, researchers at Virginia Tech and the University of Virginia are looking to change these disturbing fall statistics. With a $1.2 million grant from the National Science Foundation’s Smart Health and Wellbeing program, they are creating a portable fall prediction monitoring system for the early detection of fall risk that can provide diagnosis and treatment before a fall occurs. With the aid of the grant, a device is in the development stages that could be worn by older adults to measure potentially small declining changes in gait, posture, and mobility — all major indicators that can help point to a future fall.

The sensor will function for several days between battery recharging, collecting long-term data during everyday wear, explains Thurmon Lockhart, Ph.D., an associate professor in the Virginia Tech Grado department of industrial and systems engineering and a researcher involved with the grant. An early prototype of the sensor has already been built and tested under a previous National Science Foundation-funded project.… In-clinic studies have used a wristwatch-sized node worn on both the wrists and the ankles as well as the sacrum to collect data.… While the research is still new, the long-term hope is that this portable monitoring system will become widely available. With the technology, primary care physicians or gerontologists could make fall risk assessment a routine part of their patients’ care. “Down the road, this technology could be used in a variety of settings,” says Karen Roberto, PhD, a professor of human development at Virginia Tech and director of the Center for Gerontology and the Institute for Society, Culture, and Envi-

Aging drivers:

Docs can help elderly to give up the keys

By Lauran Neergaard Washington • Families may have to watch for dings in the car and plead with an older driver to give up the keys — but there’s new evidence that doctors could have more of an influence on one of the most wrenching decisions facing a rapidly aging population. A large study from Canada found that when doctors warn patients, and tell driving authorities, that the older folks

may be medically unfit to be on the road, there’s a drop in serious crash injuries among those drivers. The study, in Thursday’s New England Journal of Medicine, couldn’t tell if the improvement was because those patients drove less, or drove more carefully once the doctors pointed out the risk….

Lockhart has been involved in several lines of research regarding falls and has become passionate on the subject. In the US, as well as other countries, we are approaching such a significant portion of the elderly population experiencing falls that it’s on the verge of becoming a pandemic,” says Lockhart, who is also the director of the Virginia Tech Locomotion Research Laboratory and has worked with dozens of companies invested in preventing falls… Making Changes While the new remote monitoring technology is still in its early phases, there are other important intervention solutions that can be considered in the meantime. “There are prevention opportunities out there, such as strengthening programs and balance programs, that can help the patient with their musculoskeletal integrity,” Lockhart says. “Task has to be taught as well. For instance, carrying a pillow, even though it’s very light, still changes your gait. The patient can be taught safer ways to perform tasks, such as a better way to hold the pillow.” But Lockhart says it’s not just about exercise and balance training, as there’s more to falls than the musculoskeletal system. “Nutrition, the vestibular system, vision, and personal habits all also influence fall accidents,” he says. “So there has to be some risk assessment. We can test vision, and we can ask the patient some important questions.”… Lockhart says once a patient falls, the risk of falling again is very high. He believes this new technology will help reduce that risk and may even help reduce the risk of that initial fall. Lockhart says that result could be significant. “I believe we could really help some people, and that is the reason for this program: helping save lives.”

Robotic jellyfish could patrol oceans, Robotic jellyfish clean oil spills, and detect pollutants will aid Navy

Virginia Tech College of Engineering researchers are working on a multi-university, nationwide project for the U.S. Navy that one day will put life-like autonomous robot jellyfish in waters around the world. The main focus of the program is to understand the fundamentals of propulsion mechanisms used by nature, said Shashank Priya, associate professor of mechanical engineering and materials science and engineering at Virginia Tech, and lead researcher on the project. Future uses of the robot jellyfish could include conducting military surveillance, cleaning oil spills, and monitoring the environment. This isn’t science fiction. It’s happening now in a lab inside Virginia Tech’s Durham Hall, where a

600-gallon tank is regularly filled with water as small robotic jellyfish are tested for movement and energy self-creation and usage. A synthetic rubbery skin, squishy in one’s hand, mimics the sleek jellyfish skin and is placed over a bowl-shaped device covered in electronics. When moving, they look weirdly alive….

Mechanical Engineering professor Dr. Dennis Hong founded the research lab in 2004 and continues to oversee it. Eventually, CHARLI could be used for domestic chores or elder care. CHARLI has attracted notice for being the first full-size humanoid robot that could walk (without a tether) that was developed in the U.S. If it looks familiar, it may be because it was modeled on the NS-5 robots from the film I, Robot and the industrial-looking bots that appear in Bjork’s 1999

And it turns out that the Naval Research Laboratory, along with engineers and scientists at Virginia Tech and the University of Pennsylvania, is already working on something that might do the trick — though maybe not for this season. The Navy is developing a version of C-3PO, the lovable “Star Wars” robot who appeared on the big screen 35 years ago, to fight shipboard fires. The Navy robot’s name is

Autonomous Shipboard Humanoid (ASH). It’s hoped ASH will be able to walk in any direction, keep its balance at sea and go through narrow passageways and up ladders…. What’s more, ASH would be able to throw PEAT (propelled extinguishing agent technology) grenades, and be able to use hoses and fire extinguishers. The planned Navy robot is a follow-on version of Virginia Tech’s CHARLi-1 robot, which was developed by Virginia Tech’s Robotics and Mechanisms Laboratory (RoMeLa) founded and directed by Virginia Tech professor Dennis Hong.

DARPA throws down gauntlet to human-style robots

By Hal Hodsen The DARPA Robotics Challenge, one of the most rigorous tests of robotic ability ever conceived, kicked off on Wednesday. The contest sets teams of engineers from around the US and the world a set of Herculean robot trials that promise to take automatons’ abilities far beyond anything that’s come before.  The emphasis is on testing robots’ abilities to work in difficult situations in environments designed for humans. “It’s the grandest, the most exciting, and possibly the most important robotics project ever,” says Dennis Hong of Virginia Tech in Blacksburg. Hong leads a team that plans to field the humanoid THOR (Tactical Hazardous Operations Robot). THOR will be in training over the next year, learning tough skills like scrambling over debris, driving cars and climbing ladders. Previously, Hong’s team has worked on everything from firefighting to soccer-playing humanoid robots. “People might think it’s a waste of time building robots that play soccer,” he says. “But if a robot can’t play soccer, how would you use it to save people’s lives?”…

Entrants are split into four tracks. Hong and Virginia Tech are in Track A, along with six other teams, and will build robotic hardware and software for the challenge, with funding from DARPA. Track B competitors will also be funded, but will only make software, the best of which will be chosen to run a special version of the Atlas humanoid robot built by Boston Dynamics. (Virginia Tech is also part of a team participating in Track B.) Track C and D get no funding from DARPA, but can still win the grand prize of $2 million…. Hong describes the first step of the first task – opening a car door and getting into the car – as “practically impossible right now,” highlighting how much work his team must do if it is to get out of the starting blocks in the first round of the challenge in December 2013. The Virginia Tech team is in good company. Two teams from NASA will be building a robot for the competition, as well as a collaboration headed by Drexel University in Philadelphia, Pennsylvania, a team from Carnegie Mellon University in Pittsburgh, one from robotics company Schaft and another from defense contractor Raytheon.

Virginia Tech residential program helps retain female students By Sarah Bruyn Jones As a freshman, Ashley Taylor joined a small mentoring group of women who, like her, were focused on becoming engineers. In a world where few women pursue engineering, the group offered her a venue to embrace what is often characterized as a hardship. “Sometimes you kind of feel a fish out of water, like a giraffe in

a pack of zebras,” said Taylor, 20, who is preparing to enter her junior year at Virginia Tech. “You just realize that it is actually a really good thing to have a different kind of mindset as a female engineer. The mentoring program reinforces that idea.” At the Virginia Tech College of Engineering 16.7 percent of undergraduate students were women in the fall of 2011. That’s

up slightly from a decade earlier when women made up 15.9 percent of the college’s undergraduate population. Where the Blacksburg program is making strides is in its enrollment and retention of freshman women, said Bevlee Watford, the college’s associate dean for academic affairs and the director of its Center for the Enhancement of Engineering Diversity.

Last fall, 20.1 percent of freshman engineering students were female, up from 15.6 percent in the fall of 2005. And Watford said that applications among women have been steadily increasing, although she notes that overall applications are also increasing for admission to the nationally recognized program.

Getting the last laugh:

Once stereotyped as gearheads, engineering graduates are in great demand

By Gary Robertson Engineers sometimes feel stereotyped, pigeonholed and otherwise misconstrued as nerdy gearheads. But the pendulum is now swinging the other way. “There’s been a tremendous run-up of interest in engineering,” says Richard C. Benson, dean of Virginia Tech’s College of Engineering. He attributes that newfound interest to the fact that engineers now are taking the lead in areas such as space exploration, biomedical research, cyber security and advanced technology, producing culture-changing consumer products such as the iPad and iPhone. Another reason for engineering’s rise in popularity, he says, is that engineers are doing very well in a tough economy. For example, the most recent “Best Undergraduate College Degrees by Salary” survey published by payscale.com is dominated by engineering majors, which occupy seven of the top 10 spots. “I think this country is going to have an increasing need for engineers,” Benson says. “We’re not going to be economically prosperous by trying to make widgets cheaper than other countries — we are going to lose that battle.

“We’re going to become prosperous by being first with new technologies. That means engineers,” he says. Indeed, judging by the number of applications to Virginia Tech’s College of Engineering, by far the state’s largest engineering school, with an undergraduate enrollment of 6,590, the message is getting through. When Benson became dean of the school in 2005, it received 4,800 applications for 1,200 slots in the freshman class. In 2010, the size of the engineering freshman class was increased to 1,300, but the number of applications kept coming in increasingly larger torrents. This year, there were 7,171 applications, a nearly 50 percent increase over seven years. “We’re turning away students who could do the work,” Benson says, noting that the competition is fierce for admission. He hopes the school will be able to grow even larger to accommodate qualified Virginia students. Toward that end, the College of Engineering is constructing a $100 million Signature Engineering Building, thanks to a $25 million anonymous gift — the largest in the college’s history….

Students help students navigate today’s digital technology era …When the (Virginia Tech) freshman and transfer engineering students entered this fall, they were expected to purchase the following items: a convertible tablet personal computer (PC) or alternative combination of devices meeting the minimum specifications, the university software bundle, and the engineering software bundle. To some, the choice is not easy. Enter the Student Technology Council The origins of the council started in 2004 when Glenda Scales, the associate dean of international programs and information technology for the College of Engineering, so-

licited the help of students to explore the opportunity of integrating Apple’s Power-book laptops into the heavily populated, Windows PC Virginia Tech engineering curriculum. Instructions were to test virtualization tools, such as Virtual PC, to see if they could effectively run programs like Autodesk Inventor and PSPICE to use in the classroom. After much debate and examination, they answered the question affirmatively. Concurrently, Scales tasked a second group of students to test the latest convertible tablet pc, a mobile computer running an adapted version of the Windows XP operating sys-

tem with a pen-enabled interface. The tablets looked to be promising technology at the time and were adapted by the college. In fall of 2005, the Student Technology Council was officially formed to provide the college their feedback, based on their own personal experiences of using certain technology devices. This feedback impacts the college’s decisions, and helps to determine the computer requirements ... Their faculty advisor, Dale Pokorski, director of information technology for the College of Engineering, has been with the group since 2009 and views herself as the facilitator. ...

Virginia Tech’s Feng Unveils HokieSpeed By Editorial Staff Virginia Tech crashed the supercomputing arena in 2003 with System X, a machine that placed the university among the world’s top computational research facilities. Now comes HokieSpeed, a new supercomputer that is up to 22 times faster and yet a quarter of the size of X, boasting a single-precision peak of 455 teraflops, or 455 trillion operations per second, and a double-precision peak of 240 teraflops, or 240 trillion operations per second.

That’s enough computational capability to place HokieSpeed at No. 96 on the most recent Top500 List (http://www.top500.org/), the industry-standard ranking of the world’s 500 fastest supercomputers. More intriguing is HokieSpeed’s energy efficiency, which ranks it at No. 11 in the world on the November 2011 Green500 List (http://www. green500.org/), a compilation of supercomputers that excel at using less energy to do more. On the Green500 List, HokieSpeed is the highest-

ranked commodity supercomputer in the United States…. “HokieSpeed is a versatile heterogeneous supercomputing instrument, where each compute node consists of energy-efficient central-processing units and high-end graphics-processing units,” said Wu Feng, associate professor with the Virginia Tech College of Engineering’s computer science and electrical and computer engineering departments. “This instrument will empower faculty members, students, and staff across disci-

The Unified Theory of Wu

By Logan Kugler Wu-chun Feng is way too busy. An associate professor at Virginia Tech’s Department of Computer Science, “Wu,” as he prefers to be called, is occupied on any given day with professorial duties, massive technology and computer science education projects, and babysitting the university’s resident supercomputer, HokieSpeed. Wu has adapted to his breakneck schedule accordingly. Longtime colleagues marvel at his ability to work independently on his latest grant or writing project, all while carrying on a high-level conversation without missing a single beat. During a chat, Wu admits he’s running on little sleep for days in a row – even though he recently had to cancel a talk on green supercomputing in Germany. While Wu often finds it hard to say “No” to demands on his time, the type of high-performance computers he works on don’t have to. Supercomputers like HokieSpeed and Green Destiny (another project of his) take advantage of parallel computing, or using multiple processing elements to perform tasks faster. This power – both on the part of Wu and his computers – promotes a significant cross-fertilization of high-performance computing ideas, which is probably

why Wu ends up being so busy. “That’s part of the beauty of computer science and computer engineering: the understanding of abstraction,” Wu says. “The way you can take some things you’re working on and apply them in other ways you might not have otherwise thought of doing.”… Wu is part of a team of Virginia Tech researchers that are turning the university’s math lab into a supercomputer by harnessing the power of ordinary computers anytime they lie dormant. Called Project Moon, the initiative could have serious commercial applications for companies that want a healthy middle ground option between using no infrastructure at all (the cloud)

and entirely local computing infrastructures. Not to mention the “altruistic” aspects of the project. “This type of supercomputing has the promise of being able to address some ‘grand challenge’ problems that have been difficult to address,” says Wu. “Things like doing reverse engineering of the brain and finding missing gene annotations in genomes.” Wu is already pursuing those higher-minded goals by playing a big role in the Nvidia Foundation’s Compute the Cure initiative, which leverages Project Moon-style desktop computer collaboration to change how cancer research is conducted….

Those snowy slopes, sprayed with wastewater By Leslie MacMillan As I wrote in The Times recently, a ski resort in northern Arizona will become the first in the world to make artificial snow totally out of sewage effluent this winter. Last February, a federal appeals court ruled in favor of the resort, Arizona Snowbowl, ending a 10year legal battle waged by environmental and Native American groups that warned that the wastewater snow would damage wildlife, human health and a mountain considered sacred by 13 Indian

tribes. Now, apart from longstanding concern about harmful chemicals in the water that will be used to make that snow – piped directly from the sewage treatment system of the nearby town of Flagstaff – new research indicates that the wastewater system is a breeding ground for antibiotic-resistant genes. The genes were not detectable in the plant itself but “increased dramatically” at the point of use, meaning that they were found in

places like sprinkler heads, the study said. “This means bacteria is growing in the distribution pipes,” said Amy Pruden, the author and an associate professor of civil and environmental engineering at Virginia Tech. The study has not been published or peer-reviewed, but Flagstaff officials are taking it seriously enough to have invited Dr. Pruden to serve on an advisory panel that the city formed last week. Antibiotic-resistant genes are an area of emerging concern to sci-

entists because they impede the body’s ability to fight disease. Dr. Pruden suggested that the next step would be to analyze the live bacteria that might be carrying those genes through the pipes. She said the initial findings were cause for concern but that such worries “would shift to alarm” if known antibiotic-resistant pathogens were found in the water. Bacteria can cause infections in broken skin, and there is a high likelihood of cuts and scrapes during skiing, she pointed out….

Antibiotic resistance spreads through environment, threatens modern medicine By Lynne Peeples Waste from people, pets, pigs and even seagulls may be playing a significant role in the rise of antibiotic-resistant infections, including methicillin-resistant Staphylococcus aureus (MRSA), a number of new studies warn. Widespread fear of diminishing returns for modern medicine is becoming amplified, scientists say, by the discovery of soils and waterways polluted with both traces of antibiotics and bacteria encoded with antibiotic-resistant genes, the information that tells a microbe how to evade drugs designed to kill it. And even if that fortified microbe isn’t capable of causing illness in humans itself, scientists add, its DNA could find its way into the more malignant microbes in the environment. “Antibiotic resistance is likely the biggest public health challenge that we’ll be facing this century,” said Amy Pruden, an expert on antibiotic resistance at Virginia Tech. “We’re in a state of complacency right now. We count on antibiotics working for us, but they

are slowly starting to lose their effectiveness.” While progress has been made in the clinical realm – limiting unnecessary uses of antibiotics, for example, and encouraging patients to

Why restoring New York’s power isn’t easy:

The trouble with salt

By Olivia B. Waxman …Con Edison’s East 13th street substation in Lower Manhattan was built to endure a 12.5-foot storm surge. But when Hurricane Sandy hit the Big Apple Monday night, a 14foot wall of seawater inundated the area, causing a short circuit and an explosion. As a result, more than 220,000 customers were plunged into darkness in

Lower and Mid-Manhattan – the area below 39th street on the East Side and below 31st street on the West Side. Across the system – that is, all five boroughs of the city plus Westchester County – 900,000 customers lost power. For comparison, 230,821 were plunged into darkness as a result of a 9.5-foot storm surge that flooded Battery Park during Hurricane Irene in August 2011….

Electricity and water – especially seawater – do not mix. “If you put two wires in normal drinking water, they may not short circuit as easily as when you have salt in the water because salt functions as a conductor,” said Dr. Saifur Rahman, the Joseph Loring Professor of Electrical & Computer Engineering at Virginia Tech.

Levels of antibiotic resistance gene spike downstream of human activity By Laura Cassiday In river sediments, the level of an antibiotic resistance gene carried by bacteria increases when wastewater treatment plants and animal feeding facilities are nearby, according to a new study (Environ. Sci. Technol., DOI: 10.1021/es302657r). These types of facilities could contribute to the spread of antibioticresistant bacteria into the environment, the researchers say. Most strategies to curb the rise of antibiotic-resistant bacteria have focused on interventions at the clinic, such as urging doctors not to overprescribe antibiotics, says Amy Pruden at Virginia Polytechnic Institute & State University. However, she says, increasing evidence suggests that antibiotic resistance also spreads from environmental sources. When humans or animals ingest antibiotics, they excrete both the drugs and bacteria resistant to those drugs. The antibiotics and resistant bacteria then can enter rivers through

wastewater-treatment plant effluents or runoff from livestock operations.… To stanch the flow of antibiotic-resistant bacteria into the environment, researchers first need to understand the sources of the resistance genes, says Pruden. With this goal in mind, Pruden and her colleagues looked for two antibiotic resistance genes, sul1 and tet(W), in bacteria along the South Platte River Basin, in northern Colorado. Sul1 confers resistance to sulfonamide antibiotics, while tet(W) makes bacteria resistant to tetracycline…. The South Platte River Basin is ideal to study, Pruden says, because it starts in a pristine region of the Rocky Mountains that is far from human-affected bacteria and antibiotics. She uses water sediments from this region as a baseline for natural levels of antibiotic resistance genes. The river system then flows past 89 wastewater treatment plants and 100 animal feeding operations….

Vanderhyde Dairy turning manure to energy in Virginia

By Rocky Womack, AFP Correspondent CHATHAM, Va. — A Virginia dairy has invested about $1.5 million to utilize manure from their cows and convert the waste into energy for consumer use. In 2010, Vanderhyde Dairy in Chatham had an anaerobic digester system installed on their farm, which was their way of figuring out what to do with the thousands of gallons of waste formed on their farm. … The anaerobic digester converts manure from an organic form to an inorganic form, Vanderhyde says. Before the digester was installed, the Vanderhydes would spread manure onto a field, but it would take two years for the soil to break it down into an inorganic form. With the help of the digester, he says the manure will break down and be available within the same year he spreads it. The

waste-to-energy product goes through a 21-day cycle, and as long as a dairy keeps feeding the digester manure each day during that cycle, then it will keep breaking down the waste. The farm generates 25,000 gallons of waste daily and pumps it to the digester at 1,600 gallons a minute, says Jactone Ogejo, an

Extension specialist and associate professor of biological systems engineering at Virginia Tech in Blacksburg, Va. He adds that 15 feet of the manure inside the digester is broken down to produce gas. During the 21 days, he says the manure is heated to about 104 degrees Fahrenheit, which is beneficial….

Water-Saving Strategies for the CPI

Edited by Scott Jenkins By Y.A. Liu Virginia Polytechnic Institute and State University Chemical Engineering Reducing freshwater consumption and wastewater discharge at large petroleum-refining and chemical-production facilities can lower costs, while allowing plants to expand production capacities without having to secure additional freshwater resources and without having to enlarge their wastewater treatment plants. The key approaches to saving significant amounts of water are: improved water management, implementing process changes that maximize water reuse and minimize wastewater generation; and a corporate-wide focus on the “Four-Rs” - regeneration, recycling, reuse and replacement. This article describes the methodology used in several water-saving projects led by the author at large chemical and petroleum refining facilities in the Asia-Pacific region, as well as proven water-saving technologies implemented. In addition to improved water management and better use of water-saving technology, the ultimate success of water-saving projects at these large facilities depends on strong support from senior-level corporate executives and production managers, corporate-wide training of project teams and a broad effort to promote corporate-wide enthusiasm for water savings. …

cessive velocity in pipes and poor installation practices, and so each case requires fairly extensive forensic evaluation to try to diagnose the possible cause and cures,” he added. Edwards said the very standards implemented to make drinking water safe might be contributing to pinhole leaks. While disinfectants are needed, too much in some waters might be corrosive. He said research on chlora-

mine has shown it alone doesn’t eat holes in pipes, but “it is possible, even likely, that chloramine plus other factors in the water can be highly corrosive.” Well-intentioned changes to meet standards might be having unintended consequences, Edwards said. “There’s much we do know,” he said. “We’ve unambiguously proven that water can be a cause; not the only cause, but a cause. But there’s a lot we still don’t know.”

Chloramine not the answer By Julia Whiting The recent public information session on chloramine, which the Rivanna Water and Sewer Authority is planning to put in our water beginning in 2014, created several broad areas of agreement on both sides. The audience was overwhelmingly in favor of avoiding it, and seemed particularly concerned about its health and environmental effects. Perhaps more surprising was the consensus on the panel, which was created to represent differing viewpoints. There was general agreement among the panelists that granular acti-

vated carbon is the best available technology, because it takes impurities out of the water, rather than adding new chemicals that react with impurities to form even worse chemicals. Dr. Marc Edwards of Virginia Tech called it “holistic” technology.

Tough task ahead for scientists in solving water shortage crisis By Mohit Joshi Washington, January 28: Scientists and engineers have said that they will have to face a host of obstacles over the next decade in providing clean water to millions of people caught up in a water shortage crisis. The statement was made by a panel of scientists and engineers at a briefing at the Broadcast Center of the National Press Building on the Final Report on the American Chemical Society’s Global Challenges/ Chemistry Solutions. According to Marc Ed-

wards, a panelist from Virginia Tech, the reality today is that the existing plumbing infrastructure is inadequate, and scientists have insufficient knowledge about how to overcome the challenges of providing safe water to people around the world. Although Edwards stressed the importance of water conservation in meeting those challenges, he also cited unintended consequences of such efforts. He noted, for instance, that reduced-flush toilets and other water conservation methods are allowing water to remain in household pipes longer. As

it stagnates in pipes, the water could develop undesirable characteristics and have unwanted effects on household plumbing. Edwards also detailed how a change in disinfectant from chlorine to chloramine caused leaching of lead into drinking water.

Want to Grow Your Company? Find Access to R&D

By Adrienne Seiko More than two-thirds of all private-sector research and development comes from manufacturers. Where do they get their inspiration? Partnerships between universities and manufacturers, such as the Commonwealth Center for Advanced Manufacturing in Virginia, or CCAM, have played major roles in industrial R&D advancements. A number of major manufacturers, including founding members RollsRoyce (IW 100/229)  North America Inc., Canon Inc.

CCAM members have the opportunity to work with institutions such as the University of Virginia, Virginia State University and Virginia Tech. … Rolls-Royce was the driving force behind CCAM’s formation. In 2007 the company was deciding where

to locate its new aerospace facility. Rolls-Royce had centers across the United Kingdom that provided cutting-edge research, and the company thought Virginia could provide the same setup. Rolls-Royce modeled CCAM after its Advanced Manufacturing Research Center in Sheffield and Advanced Forming Research Center in Glasgow. “The goal is to create a center of advanced manufacturing that will attract the best and brightest talent,” says Lorin Sodell, plant manager, Rolls Royce Crosspointe. Bridging Research and Commercialization With competition so fierce, CCAM’s goal is to bridge the gap between research and commercialization. The group decided to focus on specific areas. “CCAM research attacks surface coating and manufacturing systems issues common to our members,” says David Lohr, CCAM’s president and executive director. “With members pooling R&D dollars and conducting research here instead of on their own production lines, CCAM translates laboratory innovation into business improvement faster and more cost effectively than ever before.” …

Aircraft designers crafting more bird-like wings By Jim Moore Turns out, those bicycle mechanics from Ohio were on to something with those warping wings of theirs. The invention of ailerons and flaps relegated warping wings to the sidelines, but a growing number of aeronautical engineers are turning back to that page and developing wings that are more distinctly bird-like, able to change their shape to best suit a given phase of flight, or offer more precise control.

The various approaches hold promise to produce future aircraft that are more nimble, efficient, and quiet.… “I think of it as like a bird (that) moves its feathers independently,” said Daniel Inman, chairman of the aerospace engineering department at the University of Michigan.... Inman and a team of students from Virginia Tech got the concept to fly, demonstrating its potential in 2010 and producing academic papers –

and a video posted on YouTube. The aerodynamic advantages of this approach include better lift to drag ratios and increased roll moments. Controls of this type respond much faster than the traditional. Imagine how fast an Extra 300 might roll with this type of control, and it’s enough to scare a person.... One of his former Virginia Tech students, Onur Bilgen, who earned his doctorate with the wing morphing work and now teaches at Old Do-

minion University, said in an email – and has written in various academic articles – that he expects morphing wings and control surfaces will eventually become the standard for aviation in general. … The idea has come full circle in more ways than one: Kevin Kochersberger, another member of the Virginia Tech team who continues to research the next generation of wing morphers today, was also See WINGS, page 27

Interdisciplinary research leads to reduced construction costs and multiple awards

BLACKSBURG, Va. – Mani Golparvar-Fard, an assistant professor of civil and environmental engineering at Virginia Tech, has developed an augmented reality modeling system that automatically analyzes physical progress on large-scale construction projects. The system allows a contractor to determine whether a project is on, ahead, or behind schedule, leading to cost savings and reduction in project delivery time. Without the need for a Global Positioning System (GPS) or any other location tracking technology, the modeling system, named the 4 Dimensional Augmented Reality or D4AR, is able to geo-spatially store digital pictures of a building in 4D (3D plus time) and integrates the photos with Building Information Models (BIM) during any and all phases of construction….

Drones in region’s skies to forever redefine privacy By Paul D. Shinkman WASHINGTON — The Virginia governor’s enthusiasm for drones has been met with concern from legal experts to the average Twitter user, while others see a technological revolution that will sharply improve law enforcement and innumerable facets of commerce and agriculture. Whatever the outcome, it’s clear drones will redefine privacy in the Old Dominion and other jurisdictions nationwide. … (The) ability for public law to trump civil law, combined with rigorous FAA regulations, could be enough to keep drones under control, says Kevin Kochersberger, associate professor for mechanical engineering at Virginia Tech and director of its Unmanned

Systems Laboratory. The university is one of only a few in the country currently licensed to deploy drones. “It’s an exciting time for lawyers and judges to be involved, because I think this is all going to come down to case law,” Kochersberger says. Most of the UAV research conducted at Va. Tech applies to humanitarian use, which he says will be typical of how the aerial vehicles are used. Existing Safeguards The process for acquiring an FAA license to operate a drone makes the use of them safer, Kochersberger says. In 2006, insurgents in Iraq allegedly hijacked a drone using only a piece of $26 software, The Wall Street Journal reported, leading some to speculate a similar crisis could occur over American soil.

However, to obtain a license, operators must first prove their drones’ “lost-link procedures” for how the device will operate if it loses its control signal. And most drones are very light, don’t fly very quickly and can only operate for 30 minutes, Kochersberger says. Much of the general concern stems from the proliferation in the media and in the public of the word “drone” itself, he says, which has historically been associated with the military and weaponry. … “Really, all this push to get more unmanned aircraft into the national airspace is not for military purposes, not for purposes to enhance defense,” Kochersberger says. “It’s really to expand commercial opportunities.”

UAVs already are being used in Japan for targeted irrigation and crop dusting, and Virginia Tech is examining similar agricultural uses. Search and rescue operations and law enforcement applications are other areas Tech is examining. A team of undergrad engineering students will travel to Australia this year to compete in the UAV Outback Search and Rescue Challenge. In this competition, teams build

UAVs that can locate a dummy in a 50-square-mile search area and drop a payload of water bottles to the “lost hiker.” UAVs are extremely valuable in disasters such as forest fires, Kochersberger says. While manned vehicles are restricted from flying over a forest fire at night, UAVs can fly surveillance missions over a forest fire for 24 hours in a row, collecting valuable data on changing burn patterns. … In law enforcement, UAVs can “look around buildings and investigate large areas that are hazardous without putting anybody in harm’s way,” Kochersberger says. “They do the dirty, dangerous jobs that nobody else wants to do.”… Managing Editor Paula C.

Weaning people onto the idea of letting the car do the driving

By Doug Newcomb What will drivers do when autonomous cars become a reality: text or tweet while behind the wheel, relax and take in the scenery, catch up on some reading or even some sleep? While you may be able to kick back once the car takes over, don’t expect to check out. And letting go of the wheel – and full control of the car – will likely happen in stages

to better prepare drivers for when cars inevitably switch to autopilot. In anticipation of autonomous vehicles hitting the road – and with advanced driver assistance systems (ADAS) such as adaptive cruise control and collision avoidance already taking some control from drivers – the US government and General Motors worked with the Virginia Tech Transportation Insti-

tute (VTTI) to conduct a study of driver behavior when they aren’t actively driving.

Hamlin returns to Richmond as NASCAR conquering hero

By Nate Ryan Basking in the afterglow of his second Sprint Cup victory this season, Denny Hamlin naturally will be heading to Richmond, Va., early this week. Denny Hamlin’s win at Kansas Speedway on Sunday gives him two victories entering one of his favorite tracks — Richmond International Raceway, where he has finished in the top five in seven of his 14 Cup starts…. The No. 11 had only one top-10 finish in the next five races, but Hamlin attributed some of that to the building of a relationship with crew chief Darian Grubb, who joined Joe Gibbs Racing in the offseason. Grubb adjusted how the team builds its Toyotas,

and it might be until mid-summer that Hamlin’s fleet fully reflects the crew chief ’s new philosophy…. Grubb, who guided Tony Stewart to five wins and the championship last year, said the communication between the Virginia natives improves each week. “I know what the inflection in his voice means,” said Grubb, who grew up in Floyd and graduated from Virginia Tech with an engineering degree that has become a valuable tool for head mechanics in NASCAR. “We’ve made our cars better, we’ve made the engine program better, (and) the communication is getting better. All those things add up to a good possibility of a performance, but then the guys on the team did a great job.”

Computer Science Students Win International Contest

For the third consecutive year, a team of Virginia Tech doctoral students of the College of Engineering’s Department of Computer Science and Center for Human-Computer Interaction has won first place in the 3D User Interfaces contest. This year’s competition required students to build a computer application that allowed two users to navigate through a complicated 3-D environment without any direct verbal communication. The Virginia Tech team, also the recipient of the “People’s Choice” award, devised a virtual search and rescue scenario that required a rescuer to enter a burning building to look for survivors as a commander monitored progress on an interactive map of the structure….

Shared transportation system would increase profits, reduce carbon emissions

The Physical Internet – a concept in which goods are handled, stored and transported in a shared network of manufacturers, retailers and the transportation industry – would benefit the U.S. economy and significantly reduce greenhouse gas emissions, according to a new study by engineers at the University of Arkansas and Virginia Tech University. If 25 percent of the U.S. supply chain operated with such an interconnected system, profits for participating firms would increase by $100 billion, carbon dioxide

emissions from road-based freight would decrease by at least 33 percent and consumers would pay less for goods…. “Our results indicate that the Physical Internet represents a virtuous cycle in which manufacturers, retailers and transportation providers all benefit in terms of increased profit margins and smaller environmental footprints,” said Russ Meller, professor of industrial engineering and director of the Center for Excellence in Logistics and Distribution….

Hurricane Sandy power outages:

Why it takes Con Edison days to get the lights back on

By Betsy Isaacson Crashing at friend’s houses, blessing our gas stoves and plugging into trees, New Yorkers are all wondering – why does it take the power so long to go back on? Con Edison’s said it could take as long as four days to restore power in Manhattan, and as much as a week in the outer boroughs. For many of us, desperately trying to preserve the flickering life of a laptop or cellphone battery, that seems too long to ponder. Here’s why it will take that long, whether we like it or not.

According to Virginia Tech professor and infrastructure expert Saifur Rahman, an electrical grid like New York’s has several key parts, each of which are essential to getting electricity to homes. First, there’s the generator – a power plant that generates electricity for large swaths of the city. That power is then pushed, at very high voltage, across transmission lines – thick bundles of metal cables that handle enormous amounts of juice. Power from transmission lines is then sent into transformers, machines that bring down the voltage of the electricity, before sending

it into small distribution lines, which transport that electricity into our homes. All of these pieces are uniquely vulnerable. “Power lines are underground in cable trenches, and if they get flooded, you have short circuit possibilities,” says Rahman. Small or backup power generators, he continues, are often in basements which flood and short-circuit the generators when a storm hits, and “substations that contain transformers are open air and they’re subject to storm damage.” … Unfortunately, electrical grids

don’t work like the web: “On the internet,” says Rahman, “there is a mesh of networks which has multiple alternate paths to get your data from point A to point B in various ways. Electrical power systems are not built that way for many reasons, one is cost, so in many cases you have one primary route and maybe a secondary route and that’s it.” If the primary distribution route for electricity to a cluster of homes is down, Rahman says, the secondary route can get overwhelmed very easily, “and sometimes, in the case of New York, you may have lost the primary and the secondary.”…

Disruption in the engineering classroom By Brian Fuller Quietly, while we worry about the state of engineering education, the university engineering curriculum is being disrupted before our very eyes. It began about five years ago when we saw the beginnings of an approach to learning that’s now ramping pretty quickly. In 2007, the Mobile Studio project came onto the scene. In short it was a lab-in-abox approach that put scope capabilities in the hands of engineering students. No need to book lab time, plus you can do your experiments in your dorm room or at Starbucks. … Lab in a box The $99 Digilent Analog Discovery Design Kit and the more advanced $199 Digilent Analog Ex-

plorer Design Kit allow students to build and test a wide range of analog and digital circuits using their own PC without the need for any other equipment. “We did it because students coming in had never touched a resistor before. And the first time they were was second semester of their sophomore year. They were unsure of electrical engineering was,” said Kathleen Meehan, associate professor in the Bradley Department of Electrical and Computer Engineering at Virginia Tech.

Why engineering students need a virtual lab bench By Kathleen Meehan Build the lab and they will come – and stand in line. Put the lab online and students can carry out experiments anywhere. That’s the basic premise behind the “Lab-ina-box” model Virginia Tech developed a few years ago – out of necessity. Virginia Tech’s department of electrical and computer engineering currently has about 625 undergrad engineering majors enrolled in beginning circuits and electronics classes, all competing for just 48 lab seats.  With three hours of lab per week, that would be 39 lab sections to schedule. Impossible. Instead, we built a better mousetrap, then put it online. Now, many

more engineering students get to experience hands-on learning wherever they are, which is especially important today.  Thanks to recent enhancements, our virtual lab bench keeps getting better while the cost per student is down to the price of a textbook. … Our students love Lab-in-a-box. The kit allows them to design, build and test various DC and AC circuits at home. Students build self-confidence as they learn to build a circuit with “real” physical components instead of “symbolic” parts. … (Kathleen Meehan is associate professor of electrical and computer Engineering at Virginia Tech.

Virginia Tech engineer defines globalization rubrick for construction BLACKSBURG, VA. — Imagine going in for a performance evaluation and the only object in the room is a report saying your work is not up to par. No explanations are provided, and no one is available to you to ask how to improve your efforts. This feeling of frustration is one many construction companies face in their efforts to go global. Looking into the abyss of globalization for the design and construction industry and the potential difficulties of cross-cultural partnerships is John E. Taylor, an associate professor of civil and environmental engineering at Virginia Tech. Taylor has created a unique lab at Virginia Tech

that conducts experiments and develops simulations that examine, model and improve systemic change in engineering networks of industrial and societal importance. One of the key areas of research, his Civil Engineering Network Dynamics Lab (www.cend.cee.vt.edu/index.shtml), investigates the impact of globalization dynamics on design and construction project performance.

Scanning innovation can improve personalized medicine New combinations of medical imaging technologies hold promise for improved early disease screening, cancer staging, therapeutic assessment, and other aspects of personalized medicine, according to Ge Wang, director of Virginia Tech’s Center for Biomedical Imaging, in a recent paper that appeared in the refereed journal PLoS One. The integration of multiple major tomographic scanners into a single framework “is a new way of thinking in the biomedical imaging world” and is evolving into a “grand fusion” of many imaging modalities known as “omni-tomography,” explained Wang, the lead author of the article.  Wang has a history of “firsts” in the imaging world, including the first paper on spiral multi-slice/cone-beam CT in 1991, on bioluminescence tomography in 2004, and on interior tomography in 2007.

L-3, Virginia Tech open cybersecurity center By Marjorie Censer Defense contractor L-3 Communications and Virginia Tech are set to formally open a cybersecurity research center in Arlington on Friday. The center, located in Virginia Tech’s Ballston research center, is meant to give L-3 employees access to the university’s labs and equipment and Virginia Tech’s faculty and students a chance to collaborate with L-3 on cybersecurity research…. Charles Clancy, who heads up Virginia Tech’s Ted and Karyn Hume Center for National Security and Technology, said the collaboration would give students and faculty more real-world experience. “Cybersecurity in particular is an area where the needs are pretty significant,” he said. “By having [the] university and a company working together so closely, we can significantly shorten the lead time between innovation and solution.”…

“The holy grail of biomedical imaging is an integrated system capable of producing tomographic, simultaneous, dynamic observations of highly complex biological phenomena in vivo,” Wang said…. The potential clinical applications for omni-tomography may improve personalized medicine.  “As an example enabled by interior tomography, an interior CT-MRI scanner can target the fast-beating heart for registration of functions and structures, delivery of drugs or stem cells, and guidance of complicated procedures such as heart valve replacement,” Wang said. Omni-tomography as a unified technology “also gives leverage to a greatly reduced radiation dose when MRI-aided interior CT reconstruction is implemented,” Wang asserted. On the other hand, “it can generate higher-resolution details in MRI images.”

Enjoy setting off fireworks, but be sure to protect those eyes

Studies show the blasts themselves don’t injure peepers, it’s the projectiles By Stephanie Pappas This Independence Day, protect your eyes. More than 2,000 people need medical attention each year for eye injuries caused by fireworks, and new research finds it’s the projectiles themselves, rather than the blast, that cause most of those injuries. In the new study, researchers used eyes from cadavers to find out, through high-speed video and pressure sensors, what happens when the human eye is subjected to the explosive power of fireworks. They found that the pressures involved aren’t enough to injure the eye on their own, as previously had been believed.

That leaves the actual projectiles hitting the eye as the main source for the 2,100 or so eye injuries caused by fireworks in the United States each year. Most of these happen during Fourth of July celebrations. “For the first time, we’ve been able to prove through this research that it’s not the blast or explosion that is causing the injuries but it’s some sort of projectile,” study researcher Stefan Duma, a biomedical engineer at Virginia Tech, told LiveScience. In any explosion, the first danger comes from the shock wave, which can cause severe internal injuries due to sudSee FIREWORKS, page 28

Cats don’t always land on their feet

By Steve Dale Here’s what can happen if you leave your window open a crack, your pet can fall out. Really, it happens. It happened to Brittney Kirk in Boston. Her cat tumbled out the window and fell 19 stories. She landed on a patch of grass, and somehow incurred only minor injuries. Dazed and confused the cat was picked up, and identified because she is microchipped (thank goodness for microchips). In a 1987 study of 132 cats brought to a New York City emergency veterinary clinic after falls from high-rise buildings, 90% of treated cats survived and only 37% needed emergency treatment to keep them alive. One that fell 32 stories onto concrete suffered only a chipped tooth and a collapsed lung and was released after 48 hours…. Cats are essentially arboreal animals: when they’re not living in homes or in urban alleys, they tend to live in trees…. “Being able to survive falls is a critical thing for animals that live in trees, and cats are one of them,” says Dr. Jake Socha, a biomecha-
