Municipalities around the world have invested significant resources to develop connected smart cities that use the Internet of Things (IoT) to improve sustainability, safety and efficiency. With this increased demand for IoT experience, the VCU College of Engineering formed the OpenCyberCity testbed in 2022. The 1:12 scale model city provides a realistic, small-scale cityscape where students and researchers can experiment with new and existing smart city technology. Sherif Abdelwahed, Ph.D., electrical and computer engineering professor, is director of OpenCyberCity. He recently answered some questions about new developments within the testbed. The OpenCyberCity is a smart city testbed, but are there any real-life cities that one could call a smart city? Several real-life locales are considered smart cities due to their extensive use of technology and data-driven initiatives to optimize infrastructure and services. Dubai is one of the most notable. They have implemented smart transportation systems, buildings and artificial intelligence to transform the city’s operations and make them more efficient. Other reputable smart cities include Singapore and Seoul, which utilize smart energy management, smart transportation and comprehensive data analytics for improved urban planning and services. Seoul, in particular, has an initiative with smart grids and connected street lights, which VCU Engineering’s own OpenCyberCity test bed is working to implement. How does the OpenCyberCity address privacy? With so much technology related to monitoring, how are individual citizens protected from these technologies? Privacy is a major concern for smart cities and it is one of the main research directions for VCU Engineering’s OpenCyberCity. We are developing several techniques to prevent unwanted surveillance of personal information. Sensitive data is protected by solid protocols and access restrictions that only allow authorized users to view the data. Our aim is to find a reasonable middle ground between technological progress and privacy rights, staying within legal and ethical bounds. Some techniques to address privacy concerns include: Data Anonymization: This makes it difficult to trace back information to individual identities. Within the testbed, we will evaluate how to protect individual privacy while maintaining data utility and assess the impact on data quality. Secure Data Storage and Transmission: Encrypt data to protect it from unauthorized access. In the smart city testbed, these access control mechanisms will be implemented within the testbed’s infrastructure. We will also test different data handling processes and access control models to determine their ability to safeguard sensitive data. Privacy Impact Assessments: Regularly evaluate potential privacy risks of new smart city projects in order to mitigate them and ensure the ethical handling of data by those with access. Policy and Regulation Development: Data and insights generated from OpenCyberCity experiments can inform the development of cybersecurity policies and regulations for smart cities. How is the College of Engineering’s OpenCyberCity test bed different from similar programs at other institutions? While other universities have similar smart-city-style programs, each has their own specialty. The VCU College of Engineering’s OpenCyberCity test bed focuses on real-world contexts, creating a physical space where new technologies, infrastructure, energy-efficient transportation and other smart city services can be tested in a controlled environment. Our lab monitors real-time data and develops smart buildings, smart hospitals and smart manufacturing buildings to enhance the city’s technologies. Recent additions to the OpenCyberCity allow for expanded research opportunities like: Advanced Manufacturing: Students can apply advanced manufacturing techniques in a controlled environment. They can also test new materials, processes and automation technologies to improve efficiency and product quality. Energy Efficiency Testing: Environmental engineers and sustainability experts can evaluate energy consumption patterns within the smart manufacturing unit to implement energy-saving measures and assess their impact on sustainability. Production Optimization: Manufacturers can use real-time data from the smart manufacturing unit to optimize production schedules, minimize downtime and reduce waste. Predictive maintenance algorithms also help prevent equipment breakdowns. Education and Training: Hands-on experience with state-of-the-art manufacturing technologies helps train the workforce of the future. Integration with Smart City Services: Data generated by the manufacturing unit can be integrated with smart city services. For example, production data can inform supply chain management and energy consumption data can contribute to overall city energy efficiency initiatives. How has the OpenCyberCity changed in the last year? Is the main focus still data security? What started with research examining, analyzing and evaluating the security of next-generation (NextG) applications, smart city operations and medical devices has expanded. Data security is now only one aspect of OpenCyberCity. Its scope has grown to encompass more expansive facets of cybersecurity like automation and data analytics in the domain of smart manufacturing systems. The implementation of a smart manufacturing system in 2023 is something students really enjoy. Thanks to the vendor we used, undergraduate students had the option to develop functionality for various features of the manufacturing plant. Graduate students were also able to research communications protocols and cybersecurity within the smart manufacturing system. What does the smart manufacturing system entail and what kind of work is occurring within that system? An automated system is there for students to work with. Robot arms, microcontrollers, conveyor belts, ramps, cameras and blocks to represent cargo form an environment that emulates a real manufacturing setting. We’re currently brainstorming an expansion of the smart manufacturing system in collaboration with the Commonwealth Cyber Initiative (CCI). We plan to set up two building models, one for manufacturing and one for distribution, linked by a sky bridge conveyor system that moves items between the locations. Students work to leverage convolutional neural networks that use images to facilitate machine learning. When paired with the advanced cameras, it forms a computer vision system that can accurately place blocks in a variety of lighting conditions, which can be a challenge for other systems. By having to optimize the communication protocols that command the smart manufacturing system’s robotic arms, students also get a sense for real-world constraints . The Raspberry Pi that functions as the controller for the system is limited in power, so finding efficiencies that also enable stability and precision with the arms is key. Is there an aspect of cybersecurity for these automated systems? Yes. Devices, sensors and communication networks integral to the IoT found in smart manufacturing systems and smart cities generate and share vast amounts of data. This makes them vulnerable to cybersecurity threats. Some of the issues we look to address include: Data Privacy: Smart systems collect and process vast amounts of data, including personal and sensitive information. Protecting this data from unauthorized access and breaches is a top priority. Device Vulnerabilities: Many IoT devices used in smart systems have limited computational resources and may not receive regular security updates, making them vulnerable to exploitation. Interconnectedness: The interconnected nature of smart city components increases the attack surface. A breach in one system can potentially compromise the entire network. Malware and Ransomware: Smart systems are susceptible to malware and ransomware attacks, which can disrupt services and extort organizations for financial gain. Insider Threats: Employees with malicious intent or negligence can pose significant risks to cybersecurity. Potential solutions to these problems include data encryption, frequent software updates, network segmentation with strict access controls, real-time intrusion detection (with automated responses to detected threats), strong user authentication methods, security training for users and the development of well-designed incident response plans.
Sleep Better, Live Better: Improving Sleep Quality Can Lead to Less Stress and Improved Cognition
Research has demonstrated that increased stress and all-night study sessions can lead to lower cognitive functioning and test scores, adding even more pressure on college students. Baylor sleep expert Michael K. Scullin, Ph.D., director of Baylor University’s Sleep Neuroscience and Cognition Laboratory and associate professor of psychology and neuroscience, studies how cognitive and behavioral processes are affected by sleep. “Sleep deprivation makes life worse. And it makes the person not getting enough sleep worse at life,” Scullin said. “However, if we focus on improving our sleep, life will get better, and we will get better at life.” Poor sleep is particularly common when students are studying for exams or working on major projects for classes. The combination of staying up late, cramming for tests, increased stress and bright light exposure late at night can lead to variable sleep durations and higher stress levels. “We know that as you accumulate sleep debt, whether it's from a single all-nighter or from weeks of variable sleep durations, it can exacerbate any pre-existing vulnerability a person may have to stress,” Scullin said. “For instance, if someone has a predisposition to panic attack disorder, sleep deprivation can increase panic attacks by about 40%. This applies to virtually any clinical or subclinical condition, whether it’s stress-related or not – sleep deprivation makes it worse.” Scullin added that even with a slight sleep deficit, any sort of negative event, such as a bad grade on a test, will feel much worse than it would for someone who is well-rested. “It becomes a cycle, and the individual begins to focus on what is worse instead of calming down at night and getting ready to fall asleep,” Scullin said. So how can a student – or any individual – break this cycle? It all starts with developing healthy sleep habits, which reduce stress and improve academic performance. Scullin suggests students try three Challenges to improve their sleep, mood and stress regulation. 1. Illuminate! Challenge One class activity that Scullin has used with students for years is called the Illuminate! Challenge, which focuses on students adding more natural sunlight to their lives in the morning hours. “About 90% of students do not know that we need natural sunlight daily in the morning to tell our internal biological clock when to start ticking. When our biological clock knows it's time to start ticking, it will make us feel more alert, which helps improve our mood,” Scullin said. Specifically, he suggests: Spending 20 minutes daily outdoors in natural daylight during the morning hours. Be intentional with this time as something aside from walking to class or other daily routines. Take the time when you would normally be inside studying or eating breakfast to go outside instead. “Almost every one of my students who has taken this challenge has said their mood and alertness improved,” Scullin said. 2. Deluminator Challenge The Deluminator Challenge eliminates light in your bedroom for a night of better sleep. Scullin said this challenge works by: Turning off all the lights and counting the number of artificial lights that exist in your environment. How many of your plugs have lights? How much light is coming in through your curtains? Cover up every light source (except fire alarms and other safety devices), including any light coming through windows. Blackout curtains are a good investment, or even using blankets to cover windows will help reduce light at night. It’s easy to adopt this challenge as it is sustainable once it is set. You will find that you can fall asleep easier and enjoy sleeping later in the morning because of the darker environment. “What normally happens is students see their devices are emitting unnatural light, and it is not nearly as dark as it should be,” Scullin said. “A lot of students in my classes report that this is their favorite challenge because it led to the biggest impact on sleep quality.” 3. Anti-Rumination Challenge Lying in bed thinking about everything you need to do the next day can increase stress levels and interrupt sleep. In a recent study, Scullin found that taking five minutes to write a “to-do” list at bedtime helped student participants fall asleep about 10 minutes faster than others who used that time to chronicle completed activities: Take five minutes to write down a to-do list of everything that needs to be done the next day. The to-do list offloads stress, gives you a good action plan for the next day and helps you feel accomplished as you check off the goals. When people get more sleep – even just one more hour of sleep per night – “they literally become happier,” Scullin said. That extra hour of sleep can improve social relationships, emotional reactions and cognitive functioning. With improved cognitive functioning comes improved academic performance. “Adding more sleep to your life makes life better, and it's going to make you better at life. It's going to resolve some of the stress, and you're going to better handle events that are inherently stressful. You're going to enjoy life while you're also taking classes. And you know what? Your grades are probably going to improve.”
Taylor Swift workshop helps fill a blank space for economics students
The University of Delaware's Kathyrn Bender developed a concept that professors could only conjure in their wildest dreams: A Taylor Swift-themed workshop that helps college students better understand data analytics through the music of the world's biggest pop star. Bender, assistant professor of economics in UD's Lerner College of Business and Economics, came up with the idea while teaching her Introduction to Microeconomics class in early October when the discussion turned to MetLife Stadium, home of the NFL’s New York Giants and Jets. “I noticed in that class there was a lot of excitement, and I had just about everybody’s attention in there, whether they were interested because of football or because of the Taylor Swift aspect. So I thought that was really cool,” Bender said. Using grant money, Bender quickly jumped on the idea and developed a Swift-themed data visualization workshop series entitled “Data Enchanted: Transforming Numbers into Knowledge.” She held three 90-minute workshops during the fall semester, which ran from late October through early December: “Ready for It,” an introduction to Stata; “You Belong with Me,” building and structuring data for analysis; and “I Knew You Were Trouble,” transforming and cleaning data for analysis. The workshops helped UD students learn to utilize Stata, a statistical software package used for data manipulation, visualization and automated reporting. They were an immediate success, as Bender received over 60 applicants, although she was limited to accepting just 32 due to space limitations. Though students don’t earn credit for completing the workshops, just a certificate, Bender said they help fill some gaps that aren’t covered in classes. “I think they’re kind of expected to learn about it, piecing it together from different classes,” Bender said. “This [workshop series] is a way for students to get introduced to thinking about data, how it’s set up, how you can create good visualizations with it … those basics before you get into the analysis.” Making the workshops Swift-themed helped students pick up concepts more easily in a fun environment. Before jumping into data sets, the students make friendship bracelets to the soundtrack of Swift's music. In one session, they pulled Spotify data and statistics to analyze the popularity of Swift’s songs. “We’ve stuck with Taylor Swift songs and albums so far,“ Bender said. “So all the data sets have been very easy for the students to understand as opposed to something that’s not as familiar for them to think about. They know what a song is, they know what the duration of a song is, those things are all very easy to understand. They’re able to practice these new data skills without having to worry about the content as much.” Due to the workshop’s immediate success, Bender is planning on expanding the program during the spring semester. She aims to hold eight workshops, the initial three and then five more, and hopes to make them available for all UD students (they were available only as an undergraduate program in the fall). Reporters who would like to write about the workshop and interview Bender can contact her directly by simply the contact button on her profile. Or, send an email to UD's media relations team.
A diverse teacher workforce is crucial for creating an inclusive learning environment for students. It brings a unique range of perspectives into the classroom, which enriches the learning experience for all students and teachers. Gary T. Henry is dean of the University of Delaware’s College of Education and Human Development and professor in the School of Education and the Joseph R. Biden, Jr. School of Public Policy & Administration. He is able to lend his expertise on this topic thoroughly. One of the key benefits of a diverse teacher workforce is the ability to connect with students from various backgrounds on a deeper level. Students feel represented and understood when they see teachers who look like them and come from similar backgrounds. This sense of connection can significantly impact their engagement and motivation to learn. As dean of the education department, Henry can discuss impacts teacher diversity can have on both students and the greater student environment. He can be reached by clicking on his profile.
Research: Add space salad to the risks astronauts face
University of Delaware researchers grew lettuce under conditions that imitated the weightless environment aboard the International Space Station and found those plants were actually more prone to infections from Salmonella. It’s been more than three years since the National Aeronautics and Space Administration made space-grown lettuce an item on the menu for astronauts aboard the International Space Station. Alongside their space diet staples of flour tortillas and powdered coffee, astronauts can munch on a salad, grown from control chambers aboard the ISS that account for the ideal temperature, amount of water and light that plants need to mature. But as the UD researchers discovered, there is a problem. The International Space Station has a lot of pathogenic bacteria and fungi. Many of these disease-causing microbes at the ISS are very aggressive and can easily colonize the tissue of lettuce and other plants. Once people eat lettuce that’s been overrun by E. coli or Salmonella, they can get sick. With billions of dollars poured into space exploration each year by NASA and private companies like SpaceX, some researchers are concerned that a foodborne illness outbreak aboard the International Space Station could derail a mission. In the new study by UD's team, published in Scientific Reports and in npj Microgravity, researchers grew lettuce in a weightless environment similar to that found at the International Space Station. Plants are masters of sensing gravity, and they use roots to find it. The plants grown at UD were exposed to simulated microgravity by rotation. The researchers found those plants under the manufactured microgravity were actually more prone to infections from Salmonella, a human pathogen. Stomata, the tiny pores in leaves and stems that plants use to breathe, normally close to defend a plant when it senses a stressor, like bacteria, nearby, said Noah Totsline, an alumnus of UD’s Department of Plant and Soil Sciences who finished his graduate program in December. When the researchers added bacteria to lettuce under their microgravity simulation, they found the leafy greens opened their stomata wide instead of closing them. “The fact that they were remaining open when we were presenting them with what would appear to be a stress was really unexpected,” Totsline said. Totsline, the lead author of both papers, worked with plant biology professor Harsh Bais as well as microbial food safety professor Kali Kniel and Chandran Sabanayagam of the Delaware Biotechnology Institute. The research team used a device called a clinostat to rotate plants at the speed of a rotisserie chicken on a spinner. “In effect, the plant would not know which way was up or down,” Totsline said. “We were kind of confusing their response to gravity.” Additionally, Bais and other UD researchers have shown the usage of a helper bacteria called B. subtilis UD1022 in promoting plant growth and fitness against pathogens or other stressors such as drought. They added the UD1022 to the microgravity simulation that on Earth can protect plants against Salmonella, thinking it might help the plants fend off Salmonella in microgravity. Instead, they found the bacterium actually failed to protect plants in space-like conditions, which could stem from the bacteria’s inability to trigger a biochemical response that would force a plant to close its stomata. “The failure of UD1022 to close stomata under simulated microgravity is both surprising and interesting and opens another can of worms,” Bais said. “I suspect the ability of UD1022 to negate the stomata closure under microgravity simulation may overwhelm the plant and make the plant and UD1022 unable to communicate with each other, helping Salmonella invade a plant.” To contact researchers from the team, visit the profiles for Bais or Kniel and click on the contact button.
Casting Light on the Dark Universe, Euclid's Mission Shows Promise
On December 7, 1968, the National Aeronautics and Space Administration (NASA) successfully launched the first functional space telescope into orbit. In the 55 years since, dozens of these crafts have embarked on missions of discovery, advancing and transforming our understanding of the cosmos. Among the latest is Euclid, a wide-angle space telescope developed by the European Space Agency (ESA). Equipped to chart portions of the universe that are not directly observable and currently shrouded in mystery, Euclid is working to generate a three-dimensional map unlike any other, surveying billions of galaxies out to 10 billion light-years. This past month, the first images from its journey were released. Joey Neilsen, PhD, is a world-renowned astrophysicist, a frequent collaborator with NASA and an assistant professor in Villanova University’s College of Liberal Arts and Sciences. From his perspective, Euclid’s early returns evidence its voyage’s incredible potential. “In Euclid’s first image of the Perseus cluster, the sheer number of galaxies is really astonishing,” said Dr. Neilsen. “We talk a lot about how the universe is mostly empty space—and it is!—but it’s also enormous, and it’s really stunning that there’s room for so many galaxies in just a small patch of sky. There are 1,000 galaxies here huddled together in this cluster and over 100,000 in the background. “I also note some pale purple patches in the image of NGC 6822. These are planetary nebulae, the layers of gas and dust blasted off by stars at the ends of their lives. It’s amazing to be able to see these so clearly in images that show the entire galaxy and its environment at the same time.” According to Dr. Neilsen, Euclid’s remarkable visuals are the product of a calculated tradeoff. The ESA craft sacrifices the fine resolution of images taken by other observatories, like NASA’s James Webb Space Telescope, to capture cosmic phenomena in greater breadth. By collecting these visuals, Euclid aims to spark breakthroughs on subjects as of yet understudied—breakthroughs that could benefit Dr. Neilsen’s field of research. “Euclid’s mission is to understand the evolution of the dark components of the universe: the invisible dark matter whose gravity holds large structures like galaxies and galaxy clusters together and the dark energy responsible for the accelerating expansion of the universe,” he explained. “Much of my research focuses on a different aspect of the dark universe (black holes), but there is a puzzle that might connect: observations of very distant galaxies show there were very massive black holes very early on. How did these behemoths grow so big so fast? If would be neat if Euclid helped us to better understand the early universe in a way that informed our understanding of the growth of black holes.” In tracking and investigating the dark entities that compose and mold the cosmos, Euclid could very well offer insights into the history and development of over 95% of all energy and matter—and perhaps into the very fabric of existence itself. It is reasonable to wonder whether, when its mission is complete in six years’ time, the telescope could provide us with answers to questions that have gone unaddressed for six billion years. “For me, the best-case scenario would be that Euclid would show clear evidence of something that’s hard to explain with our current models,” said Dr. Neilsen. “For example, right now, we have ‘Hubble tension,’ a discrepancy between measurements of the expansion of the universe from when it was young and from the current era… The moments when things don’t add up are the ones where we learn the most about how the universe works. So, I’ll keep my fingers crossed for a surprise and for more to learn over the next six billion years.”
Big shift coming to the EV industry
Already a pioneer in the industry, the University of Delaware has once again played a key role in taking electric vehicles to the next level. Researchers there helped bring about new automotive standards that will drive lower-cost charging and vehicle-to-grid (V2G) integration and standardize Tesla’s connector so that future U.S.-made EVs will have this technology on it. The two newest standards for electric cars, both approved this month by standards committees of SAE International (formerly the Society of Automotive Engineers), should bring EV drivers great joy, according to Willett Kempton, professor at the University of Delaware’s Center for Transportation Electrification on UD’s Science, Technology and Advanced Research (STAR) Campus. Center director Rodney McGee was chairman of the two SAE committees, while postdoctoral researcher Garrett Ejzak, Kempton and administrative assistant Becky Cox played key roles in the engineering, research and policy work undergirding the new EV standards. “These developments mark a big shift for the EV industry,” said Kempton, who is affiliated with research centers in both the College of Earth, Ocean and Environment and the College of Engineering at UD. “Drivers will gain access to more charging stations and lower-cost charging. They will have new options for using their EV to help fight climate change and even make money when plugged in. These changes are likely to spur even greater adoption of EVs for clean, affordable transportation.” The so-called “V2G standard” (SAE J3068) provides the missing link for widespread use of vehicle-to-grid (V2G) technology, which Kempton and his colleagues invented at UD more than two decades ago. “We’ve been doing V2G for 20 years here at the University of Delaware, wondering when the rest of the world would catch on,” Kempton said. “One key missing piece has been a complete standard for controlling and managing V2G, which now exists within SAE J3068.” V2G allows you to plug your EV into an electrical outlet and send power from the car battery back to your local energy utility, making a little income while helping the nation’s power grid. This is becoming increasingly more important as more renewable sources of energy come online. When the sun isn’t shining or the wind isn’t blowing, EV owners can plug in and “perform important energy-balancing services,” according to Kempton. The savings from V2G can add up. “Our V2G demonstrations show an EV can earn between $100 a year and $1,500 a year. The wide variation is due to different markets and to regulations in different utilities. It also depends on the EV’s capabilities,” Kempton explained. Current EVs need a substantial update or retrofit to be able to do V2G, while new EVs equipped with the signaling technology are expected to be available by 2025. This standard also will make it possible to use your EV as backup power for your house. As extreme weather increases with climate change, that’s a good energy reserve to have when the lights go out. It takes one-and-a-half kilowatts to power the average house, Kempton said. Your electric car can produce 80 kilowatts of power, enough to run a whole house and more. “So, your EV can both help fight climate change and keep your house going when extreme storms happen,” Kempton said. With SAE J3400 now approved, the connector system Tesla developed for EV charging will now be standardized and can be included on future EVs of any brand. The first non-Tesla cars with this technology, also known as the North American Standard Connector, are expected to hit the market in 2025. “This will eliminate Tesla’s monopoly on their charging stations, making them available for use by any new EV,” Kempton said. According to Statista, the U.S. had more than 53,000 public EV charging stations and over 138,000 public charging outlets in May 2023.
