To many people, it makes sense to keep transit bus windows wide open, drawing in cross-ventilating air for passengers seeking safety from the COVID-19 virus. But opening windows might not be the best way to protect transit riders from viral particles. Instead, to reduce exposure to infection, bus operators might close all windows and operate air-filtration systems at top performance, according to Mesbah Uddin, director of the North Carolina Motorsports and Automotive Research Center at the University of North Carolina at Charlotte.

“When a bus’s air-filtering system is working at 100% effectiveness, it captures many viral particles and prevents their dispersal,” said Uddin, professor of mechanical engineering and engineering science. “It turns out that air filtration performs a better job of improving passenger safety than open windows in cross-ventilating the bus interior.”

Uddin’s research team began studying air safety for public transportation by precisely measuring a standard Charlotte Area Transit System bus, assisted by CATS staff. The team entered the measurements into a computer-aided design (CAD) model of the bus interior. The model was embedded in a computational fluid dynamics (CFD) model, which is commonly used in aeronautics, auto design and other fields to illuminate how gases or liquids move in space and across and around surfaces.

Productive Partnership

The UNC Charlotte researchers’ partner, Corvid Technologies of Mooresville, North Carolina, allowed the team to explore various options for protecting passenger health by providing hundreds of training hours on its proprietary RavenCFD program.

Specifically, the team modeled injections of three characteristic respiratory particle size distributions — from speaking, sneezing and coughing — into the driver’s area of the cabin, then analyzed simulations of airflow and airborne particles along the cabin’s length.

The model was configured with various passenger seating arrangements, seat-barriers placements, windows-open alternatives and heating-and-air-conditioning system (HVAC) settings. Simulations tested how particles in airflow were dispersed, diluted, concentrated or filtered out while the bus was in motion. More than 7 million hours of computing time were dedicated to this project over a tight timeline of two months.

As the researchers expected, airflow through the cabin was redirected by passengers and other large objects. “When airflow reaches one of these large objects, it can create eddies much like a stream current does when it encounters rocks,” said Greg McGowan, an aerospace engineer with Corvid Technologies.

When this happens, airflow stagnates and particles remain in place, recirculating in one spot, possibly to the detriment of passenger health.

“We want transportation systems to have the best standards for the health of the passengers,” said Vincent Lee, a Ph.D. candidate in mechanical engineering and one of three graduate students on the research team. The others, Will Timms and Muhammad Usman Zafar, completed master’s degrees in mechanical engineering in May.

Assessing the threat of surface-transmitted viral particles

 

A team of researchers from UNC Charlotte’s Department of Bioinformatics and Genomics — curious about how SARS-CoV-2 RNA, the virus that causes COVID-19 spreads and accumulates on surfaces — collected samples from Niner Transit, the campus bus system, to learn more about the possible presence and transmission of the virus from high-touch surfaces. Lauren Roppolo Brazell, a doctoral candidate in bioinformatics, talks about what they discovered and what they hope yet to learn.

A Win-Win

Joint efforts such as the one between UNC Charlotte and Corvid Technologies demonstrate the value and impact of academia-industry partnerships. “We were able to collaborate on a highly computational project in a timely and cost-effective manner,” said Elizabeth Coakley, director of corporate development, Corvid Technologies. “We came up with great results in a matter of months. You just can’t do that unless you work together.”

In addition, the opportunity to contribute to a discovery with potentially far-reaching applications makes a difference for graduate researchers as they launch their careers.

“During this project, we learned to analyze simulation data for different conditions and look for interesting patterns and trends,” said Lee, who is participating in a summer internship with  NASA. “It is this kind of experience that has helped me explore and develop my career with its concentration in motorsports and specifically focusing on aerodynamics and turbulence modeling.”

McGowan concurred. “It’s been exciting for us to be involved in ‘bleeding edge’ research,” he said. “We’re always looking for grad students who have these skill sets. Giving them this experience is beneficial for all involved.”

New questions to explore

The study is generating new questions, such as what might be learned from additional research that examines airflow and particle behavior in instances when HVAC efficiency is reduced. “We started out assuming that air filters on a high setting would be very effective in eliminating foreign particles,” said Uddin. “But what if high-efficiency HVAC systems, which prove better for reducing particle transmission, are not widely available in transit buses in the real world?” 

A second question involves the relative health dangers from different or new viral concentrations in particles. “We don’t know what concentration of particles would create a higher risk of infection,” said Uddin. “To incorporate that information, we will need a slightly different methodology.”

Uddin notes that the data and methods developed by the research team could lead to understanding airflow and particles in other closed spaces such as aircraft or ships, or in certain urban environments. “These tools could help track the spread of a future virus or any foreign agent, such as the weapons used in chemical or biological warfare,” he said. “It’s entirely possible to develop warning systems to prepare our population for the safest ways to reduce our exposure to a virus or a foreign agent.”

THE RUNDOWN ON DATA SCIENCE

Sorting through the data

While the driving force behind the data science revolution is the sheer amount of data being produced, at its core is the field’s desire to interpret and create meaning from data to spur innovation and inform decision making.

Why it's important

As institutions and organizations expand their analysis of data, the promise for data science is realized every day through innovation such as self-driving cars, new medical diagnoses and treatments, and more reliable weather forecasts. As society is learning, it is equally important to train a generation of professionals to engage in the larger ethical issues embedded in data science like the reinforcement of existing biases, lack of transparency in artificial intelligence, and data privacy and use.

The industry is booming

Since 2012, the field has created 8 million jobs in the United States alone and 6 million more worldwide. Glassdoor, a popular job site, rated data scientist as the No. 1 job in its annual list of 50 Best Jobs in America from 2016 to 2019.

Demand is outpacing supply

While industry growth is roaring, job demand still outpaces the supply of qualified professionals. In 2018, the United States experienced a shortage of 151,000 data scientists, a gap that is expected to jump to 250,000 by 2025.

Answering the call

In 2013, recognizing the vital role of data science to a number of disciplines and organizations, UNC Charlotte made it an institutional priority. What started as the Data Science Initiative has become the School of Data Science — the first and only academic unit of its kind in the Carolinas — which launched in early 2020.

Building the talent pipeline

Data science at UNC Charlotte earned the early support of regional business partners. Business leaders recognized the program established a talent pipeline for highly skilled data science professionals and served as an expert resource for continuing education and external research.

When Rob Keynton arrived at the start of the 2020-21 academic year to lead The William States Lee College of Engineering at UNC Charlotte, he applied the same expert problem-solving skills he uses to tackle puzzles — a favorite pastime.

“To me, determining the college’s direction for the next several years represents a great big puzzle,” Keynton said. “Assessing our strengths and opportunities, remaining on the leading edge of offering high-impact learning environments, and nurturing and fostering innovation all are priorities.”

During his first semester as dean, leading the experience of nearly 4,000 engineering students at the undergraduate and graduate levels and faculty who teach in the college’s 22 academic programs, Keynton has focused on gathering input from students, faculty, staff and key stakeholders throughout the community and various industries.

“This process will lead to envisioning how the pieces fit together for identifying key areas for growth,” he said.

The task can be complex, even for someone with Keynton’s credentials. An elected fellow in the American Institute for Medical and Biological Engineering (AIMBE), the Biomedical Engineering Society (BMES), and the National Academy of Inventors (NAI), Keynton came to UNC Charlotte from the University of Louisville, where he was interim executive vice president for Research and Innovation and the Lutz Endowed Chair of Biomechanical Devices in the Department of Engineering at the Speed School of Engineering.

Expertise in the development of biomedical engineering applications such as micro and nano technology systems, biomaterials and lab-on-chip devices provides a foundation for guiding the Lee College of Engineering’s recognized leadership in precision metrology, energy, motorsports and optics and developing new areas of expertise.

“Engineering and innovation are more important than ever to our world as we work to develop solutions to environmental, energy production, biomedical, infrastructure, manufacturing, communications and other technological challenges,” he said. “That’s why this job is the perfect fit for me.”

 

Dean Rob Keynton

The puzzle begins to come togther

Keynton’s early impressions will provide a framework for envisioning priorities for the next several years, a plan that will be based on the University’s new strategic plan due in spring 2021. In the meantime, central to the success of the William States Lee College of Engineering will be collaborative leadership, innovative research, industry and nonprofit partnerships, and a commitment to diversity.

Dean as team leader

“I enjoy building programs and teams to accomplish goals and visions,” said Keynton, whose vision at Louisville led to the creation of the bioengineering department and program, which gained national recognition when the latter was named a Wallace H. Coulter Foundation Translational Partner.  “I see myself as a facilitator or coach whose job is to make teams more successful.”

Research leads to impact

“A number of research projects are underway in transportation, energy, precision metrology and more whose outcomes will lead to practical application as well as further research opportunity,” he said in reference to a portion of the $16.5 million in external research support that the College of Engineering drew in 2018-19 and continues to grow.

Partnerships fuel the workforce

“Collaborating with industry and community organizations is essential to developing next-gen leading-edge technologies and products for solving real-world problems–and they provide an excellent training ground for our students and build the skilled workforce that our partners need.”

Diverse students, faculty and staff enrich the field

“It’s essential for engineering in general, and the William States Lee College of Engineering in particular, to be represented and informed by a number of perspectives,” said Keynton, speaking from personal experience as a son of a Puerto Rican immigrant. “Preparing a new generation of engineers in a global environment is a critical task, which we will achieve as we work together.”

ROUGHLY ONE MILLION TOTAL KNEE REPLACEMENT PROCEDURES ARE PERFORMED EACH YEAR IN THE U.S.

With sensors attached to her body, Lena Thompson cautiously climbs up one step, then a second and finally a third. Once at the top of a raised platform, she walks forward, stops, turns and descends the stairs—and repeats the exercise several times. Researchers from the William States Lee College of Engineering at UNC Charlotte observe Thompson, who recently underwent knee replacement surgery, as she performs the exercises as part of a project examining the effectiveness of knee implants.

Last year, Thompson, a retired daycare worker, visited the Biomechanics and Motion Analysis Lab directed by Nigel Zheng, a professor of mechanical engineering and engineering science who joined UNC Charlotte in 2008. She completed a number of exercises prior to surgery and had returned for post-surgery analysis.

As is the case with many patients, pain was the determining factor for Thompson as she considered knee replacement. “Excruciating” is how she described the agony she’d endured for the better part of a decade.

Mechanical medicine video

“I could hear the bones rubbing together when I walked; the pain was so bad I felt like falling to the floor,” she said. She tolerated the pain, undergoing periodic steroid injections to alleviate the discomfort.

Before surgery with OrthoCarolina, Thompson’s orthopedist mentioned that Zheng, a world-renowned authority on biomechanics, was seeking participants for a study related to knee implants. Through his work, Zheng has seen the positive impact of biomechanical research on the design of medical devices, prostheses and orthoses, exercise equipment, surgical instruments and other products.

“Mobility is very important to one’s life,” he said. “Patients with pain and limited mobility often lose hope of achieving a good quality of life. Our work has the potential to help people maintain their health, leading to greater productivity and efficiency in their everyday lives.”

NEXT GENERATION OF ENGINEERS

According to Zheng, those best suited to help solve complex, medical problems of the future are those he describes as “the next generation of engineers.” He takes seriously his role as a mentor, fostering a passion for this work in his students.

Junior Marc Duemmler has taken several courses taught by Zheng and now assists in his lab.

“In my Introduction to Solid Mechanics class, Dr. Zheng related the course material to biomedical engineering, and how he applied the material using real-life examples piqued my interest,” said Duemmler, who is majoring in mechanical engineering with a concentration in biomedical engineering. “I have taken his Orthopedic Biomechanics course, and I am currently enrolled in his Introduction to Biodynamics course. He always has an example of either his research or conducted by a researcher that he knows that is applicable to the concepts we are learning.”

In Zheng’s lab in Duke Centennial Hall, students like Duemmler gain practical experience, often conducting research with participants such as Lena Thompson. In the classroom, they propose study topics to tackle as teams.

Lena_Zheng_FINAL3
knee_chart_FINAL3

“I teach through actual scenarios that have implications for human health,” said Zheng. “Critical thinking and problem solving—beyond mimicking what is done in class—are essential to students’ development as researchers. Learning to learn is vital, as today’s knowledge gives way to new knowledge. Engineers must be prepared to examine each problem for its unique features.”

Duemmler is appreciative of the chance to participate in hands-on research as an undergraduate.

“Getting to work with Dr. Zheng and his graduate students has given me first-hand experience that I think most undergraduate students will never experience. Just in the past year, I have gotten to learn so much about biomechanics just from conversations with him. I truly value the experience and knowledge that Dr. Zheng has, and I hope to learn as much as I can from him,” he said.

THE HUMAN MACHINE

UNC Charlotte’s location within the state’s largest metropolis allows Zheng and his lab to collaborate with OrthoCarolina, Atrium Health and other health care providers and product manufacturers in the region.

“Our research often changes the way a medical problem is solved—from implant design, refinement of surgical tools and procedures, or post-surgery rehabilitation,” noted Zheng. “Relationships with the region’s leading health care providers allow us, for example, to offer insight related to medical image-based evidence of higher wear rates due to contact stress for metal-on-metal hip implants, fall risk assessments or the biomechanical evaluation of surgical techniques for ACL reconstruction.”

Lena_Zheng_FINAL3
knee_chart_FINAL3

Currently, Zheng is gathering data related to knee joint function and pain levels prior to surgery and how different implants restore some functionality post-surgery.

“We ask questions such as, ‘Does the design meet the needs of some or all patients? Which features work for specific groups of patients?’” said Zheng. “As a biomechanics researcher, I study the body’s dynamic features and functions. Medical imaging makes that possible as it explores the structure of the human machine.”

UNC Charlotte fuels energy research and advances the future of the solar industry

Transforming Sunlight into Energy
North Carolina is the number two solar producing state in the nation and UNC Charlotte is at the forefront of this growing industry.

Industry Growth

The latest data from the U.S. Energy Information Administration cemented North Carolina’s position as the number two solar power producing state across the nation. Annual solar energy production in North Carolina jumped 36 percent in 2018, a much larger increase than experienced by solar leaders such as California, Nevada and Arizona.

Few industries are experiencing the rate of growth seen in the solar industry. According to the 2017 Solar Jobs Census, from 2012 to 2017, one of every 100 new jobs was in the solar industry, which now employs approximately 250,000 U.S. workers.

#2 in USA for solar capacity

As the industry grows, North Carolina continues to cement its place among the solar energy leaders in the United States.

“In North Carolina we have the second-highest capacity of any state to connect solar power to the grid – behind only California,” said Dr. Mike Mazzola, executive director of UNC Charlotte’s Energy Production and Infrastructure Center (EPIC). “Actually, we’re number one in utility-scale solar power, because a lot of California’s generation is from residential roof-top solar panels.”

As North Carolina’s urban research university, UNC Charlotte’s mission is to deliver high-quality, high-impact research that addresses regional needs to improve and support its citizens and industry. Considering the state’s emergence within the solar energy landscape, this mission makes the William States Lee College of Engineering’s solar energy work extremely important.

Solar power production in North Carolina is expected to grow even faster in the next decade, thanks in part to N.C. House Bill 589. The measure, a collaboration between utility officials and solar interests, establishes a competitive bidding program and a solar power leasing program.

250K Americans working in solar; 1.7M solar energy systems installed nationwide

“By allowing third-party solar producers to sell power to the grid, residential solar production in North Carolina will take off in the next few years,” noted Mazzola. “With South Carolina and Georgia also adding capacity, making this region is an even greater solar producer.”

A growing solar industry creates an increased demand for solar engineers to fill the workforce required to design, build, operate and maintain it. To prepare these future engineers, the Lee College of Engineering offers numerous solar-related educational programs at the undergraduate and graduate levels.

EDUCATING SOLAR ENGINEERS

“The founding mission of EPIC is workforce development,” said Mazzola. “At the Lee College of Engineering, we give students a taste of renewable energy, including solar, as part of their education. These efforts help inspire students who are excited and motivated about the future of renewable energy.”

Classroom learning is focused on the principles of photovoltaics and tackling hands-on learning projects. Students apply that learning in the University’s state-of-the-art laboratories through research aimed at designing improved solar cells, developing technologies for delivering solar power to the grid, and advancing methods for storing and using solar power at maximum efficiency. Many students serve as research assistants partnering with their faculty mentors on solar-related research.

“At both the undergraduate and graduate levels there is an educational environment and culture surrounding our students that deals with the very-real issues involved in renewable energy,” Mazzola noted.

COMPREHENSIVE RESEARCH

The University’s approach to solar energy research is to improve solar energy as it strives to become a key power source for the future.

The college of engineering impacts solar energy from the fundamentals of producing better materials for solar cells, to the incredibly complex issues of how to use and store photovoltaic generated power for the grid.

“With our state-of-the-art EPIC facilities, we are able to carry out solar research on a number of levels,” Mazzola said. “In our Photovoltaic Technology Research, Photovoltaic Integration, Renewable Power, Smart Grid, Flexible Energy and other laboratories, we study, develop and test solar energy research. This is important to our researchers and makes us an attractive full-service applied research partner for working on grants with business and industry.”

Infographic: how sunlight becomes energy

A key area of solar power research to watch is the prediction, storage and use of solar generated power.

“Since we don’t always know when people are going to turn on their lights and use power, there is always a degree of uncertainty about the timing of demand,” said Mazzola. “With solar energy now accounting for roughly 10 percent of generation during the day, questions of supply and demand become more complex.  And it will only intensify as more people generate their own residential solar power to use and sell to the grid.”

LOOKING TO THE FUTURE

As the solar industry evolves, advanced solar technologies will continue to be developed and refined. As legislation makes solar power a more viable technology for home owners, its management will become more complex.

“Solar power engineers will be needed to solve future problems,” said Mazzola. “At UNC Charlotte, we are educating and preparing these engineers, and continually integrating more solar and other renewable energy studies into our curricula.”

The social sciences, and even political science, will play a bigger role in the future management of solar power, as consumer mindsets about energy use begin to change.

The commercial and residential sectors of solar energy are already on the minds of a number of startup companies that are partnering with the University to use its applied solar technology research for the purpose of commercializing photovoltaic power solutions.

“We’ve become a leader in entrepreneurship,” explained Mazzola. “Beyond working on the fundamental problems of the technology, we are also spinning off a number of companies. This application of research directly impacts North Carolina’s future by creating jobs and strengthening our economy.

“Right now, the amount of power we generate follows the amount of energy load that is needed,” said Mazzola. “However, we’re seeing indications of a complete reversal in the future, which means load demand will follow generation capability. The research in our laboratories and technologies developed by our spinoff companies are going to be vital to the creation of and management of solar power. At UNC Charlotte, we’re looking forward to it. We’re here and we’re ready.”

Growing up, Chris Long ’06 never gave a lot of thought to the inner workings of race cars while watching his father, an amateur road racer, race tracks along the east coast. But now, Long, who earned a bachelor’s degree in mechanical engineering from UNC Charlotte and has worked for 12 years in motorsports, says engineering has taught him how to be a better problem solver.

An engineer with Chip Ganassi Racing, Long has had a hand in improving the ergonomics of the team’s cars, helping to mold their shape to make them faster. As a member of the simulation team, he uses computer simulations to measure vehicles’ input and output. And as leader of the quality control team, Long verifies that parts built in-house meet design specifications and ensures that parts from outside vendors meet the proper tolerances.

“I don’t know if I’d be able to do what I do without an engineering degree,” Long said.

As the pace of competition has increased, so has the number of engineers working in NASCAR. It’s a trend that can be traced to the late Alan Kulwicki, NASCAR’s first driver to hold a degree in engineering—and who was inducted into the NASCAR Hall of Fame on Feb. 2.

Kulwicki’s NASCAR success was sown in independence. Bucking the tradition of the Southern-bred driver, Kulwicki, a Wisconsin native, earned a degree in mechanical engineering from the University of Wisconsin-Milwaukee. Choosing to race independently, he shunned big-name sponsorships throughout his career. Tragically, a year after winning the 1992 Winston Cup Series, Kulwicki died in a plane crash near Blountville, Tenn., at age 38.

Kulwicki’s dedication to his sport is celebrated at UNC Charlotte, where the Alan D. Kulwicki Motorsports Laboratory trains engineering students interested in motorsports to design, build and race their own cars. Ryan Zeck ’99 started a petition to implement the motorsports program, and Bob Johnson, now dean of the William States Lee College of Engineering, proposed the program during his tenure as head of the mechanical engineering department.

A renewable scholarship in Kulwicki’s name is funded through the R.J. Reynolds Tobacco Company and given to a UNC Charlotte freshman majoring in mechanical engineering.

‘BULL IN A CHINA SHOP’

Memories of Kulwicki flow freely from his friend Felix Sabates, co-owner of Chip Ganassi Racing, many of them referencing Kulwicki’s characteristic frugality—as well as his generosity.

Kulwicki owned his cars, but would rent transmissions, gears and other parts for them. “He won with almost no money.” Sabates said. “He had to be tight with his resources because he didn’t have any.”

Sabates recalled that he had to almost force Kulwicki to buy a house after his Winston Cup victory. Yet, he said Kulwicki would write a big check annually to a Boys and Girls Club in Florida, an organization with which Sabates was heavily involved.

Money was not something that motivated Kulwicki. Winning races did. And he did what it took to do so.

“He was like a bull in a china shop,” Sabates said. “When he made up his mind to do something, he got it done.”

As an engineer, Kulwicki understood mechanics and aerodynamics, and performed work on his car by hand that today machines complete. Driven by his analytical mind, he remained grounded through his faith, attending Mass no matter where he was. Even if that meant driving hours to find a Catholic church.

Sabates underscored Kulwicki’s playful side, sharing the time he bet Sabates about how fast he could drive through a McDonald’s parking lot at 1 a.m. He described Kulwicki’s legacy as giving hope to talented young drivers “who come from nowhere.”

PICKING UP THE PACE

When Chris Long joined Chip Ganassi Racing, he was one of 10 engineers; a number that has expanded to nearly 30 who work on just the NASCAR side of the operation. (The team also has cars competing in the IndyCar Series.) These engineers work in every area of the team’s operations, including simulation, design and quality control.

“Definitely quite a transition over the past 10 to 15 years for a sport that’s been around for 50 to 60 years,” Long said.

UNC Charlotte’s engineering programs reflect the industry’s growth. As recently as 2012, the University’s motorsports engineering program enrolled fewer than 80 students. Today, more than 160 students are enrolled across programs.

According to Mesbah Uddin, director of the University’s North Carolina Motorsports and Automotive Research Center, in the 1980s, despite Kulwicki’s groundbreaking credentials, it was unlikely that NASCAR teams included any engineers with a degree from an accredited university. “Team members performing engineering work learned primarily while working on their dads’ cars,” he said. “They’re extremely talented people.”

But cars were simpler then and the pace of competition was slower. In the absence of sophisticated computer systems and qualified engineers to process vast amounts of information—such as how the various components of race cars interact with one another on different tracks and under different racing conditions—racers and teams relied mostly on trial-and-error-based designs.

Uddin said as NASCAR rules became stricter in the 1990s and design freedoms narrowed, racing teams realized the limits of the trial-and-error approach. They began hiring more engineers to design cars that, to a great extent, eliminated the guesswork from design and development. Today it’s not unusual for a race team to include between 20 and 40 engineers.

“We see that making quicker changes is necessary because the competition is becoming more fierce,” Uddin said. “The quicker that changes can be made, the more races can be won.”

Long said the increase of engineering professionals in NASCAR has led to safer and more efficient cars on the track.

90% of Monster Energy NASCAR Cup Series teams are within 50 miles of UNC Charlotte; 15% of all NASCAR engineers are UNC Charlotte graduates

“Knock on wood, we haven’t had any major injuries in the sport in quite a few years,” he said.

Long described the number of UNC Charlotte alumni in the industry as “impressive.” He said the University has a “top-level, state-of-the-art” racing shop, which familiarized him with the equipment he uses on his job.

“I love that UNC Charlotte offers a designated motorsports concentration,” Long said. “Students work on real cars on which you can apply textbook knowledge and gain real-world application and theory.”
