Diamonds Could Replace Silicon in Some Semiconductors

Many companies working on next-generation nuclear reactors lack the infrastructure, lab facilities and computer models needed to collect the data required to prove to the U.S. Nuclear Regulatory Commission (NRC) that their designs are safe and will work. To give some of these companies a leg up, the U.S. Energy Dept. recently awarded $30 million in initial funding to each of five U.S. teams so they can address the technical, operational and licensing challenges in bringing their designs to market.…

Nearly 300,000 deaths could be averted, depending on how severe isolation measures become — ScienceDaily

This summer, when bars and restaurants and stores began to reopen across the United States, people headed out despite the continuing threat of COVID-19. As a result, many areas, including the St. Louis region, saw increases in cases in July. Using mathematical modeling, new interdisciplinary research from the lab of Arye Nehorai, the Eugene & Martha Lohman Professor of Electrical Engineering in the Preston M. Green Department of Electrical & Systems Engineering at Washington University in St. Louis, determines the…

Evolving Power over Ethernet Expands Power Distribution

What you’ll learn: Advantages of Power over Ethernet in the context of industrial Ethernet. PoE standards continue to evolve to keep pace with increasing power demands. Driver for standards updating is the potential movement toward Gigabit Ethernet.   Industrial Ethernet has disrupted factory automation through its improvement in speed and latency performance. Engineers achieve these conditions by employing 100-Mb/s fast Ethernet in switch mode with full-duplex capability. This design unlocks point-to-point device connectivity, creating an Ethernet solution to help manage…

Building Smarter AI – University of Missouri College of Engineering

Associate Professor Derek Anderson is working to improve the way artificial intelligence responds to environments. Artificial intelligence is smart, but it’s also too trusting. Currently, AI blindly trusts sensor data and decisions derived from that data. Now, Derek Anderson, an associate professor of electrical engineering and computer science, is trying to figure out how to build AI that can more intelligently react to dynamic unknown environments. With a four-year grant from the U.S. Army Engineer Research and Development Center (ERDC),…

Cornell University to extract energy from manure to meet peak heating demands

An integrated biorefinery approach utilizing agriculture waste biomass to produce renewable biomethane along with other co-products (for soil amendment, nutrient recovery, and transportation biofuels). Credit: Nazih Kassem, with images from Cornell University, Department of Energy Cornell University is developing a system to extract energy from cattle manure to meet the campus’s peak demands for heat in the winter months. In the Journal of Renewable and Sustainable Energy, scientists involved with the project give a detailed analysis of the issues required…

Mizzou Engineers Using Twitter to Track COVID-19

Mizzou Engineers are taking to Twitter to track COVID-19 and analyze the virus’s impact on individual health. Yijie Ren, Jiacheng Xie and Lei Jiang are using Twitter’s built-in programming interface to search tweets for key phrases such as “I tested positive.” From there, they’re delving deeper into the Twitter user’s account to log symptoms and recovery experiences. Yijie Ren Over the years, Twitter has become a popular database for researchers who want to mine real-time information—making it an ideal spot…

Professor Helping Develop Better Way to Diagnose COVID-19

A Mizzou Engineer has teamed up with a company to help develop a better way to diagnose COVID-19. Dong Xu, Shumaker Professor of Electrical Engineering and Computer Science, is working with a company applying nanopore sequencers to test DNA samples for the virus. Xu will then help develop a system to analyze the DNA data. Dong Xu “DNA contains many other sequences, including other viruses and bacteria, so we will sort it out to identify whether there is any coronavirus…

Protein Prediction Challenge Makes History – and Mizzou Engineers Rank in Top 10

A protein’s 3D structure determines how it will function. Mizzou Engineers demonstrated ways to predict protein structures at this year’s CASP14 event. Mizzou Engineering students took on tech giants at a worldwide competition last month and came home in the top 10 for devising a way to accurately predict protein structures. And in subcategories, Mizzou teams ranked in the top 3. What makes this especially notable is that this was a historic year for the 14th Critical Assessment of Structure…

Laser Scanning Accelerates Power Plant Conversions to Natural Gas

Over the past decade, more than 100 coal-fired plants have been replaced or converted to natural gas, according to the U.S. Energy Information Administration. Key factors pushing coal plant owners to make the changes include stricter emission standards, lower natural gas prices, and the emergence of Combined Cycle Gas Turbine (CCGT), a new, more efficient natural gas turbine technology. CCGT plants are more efficient than coal plants because use the heat generated from fuel combustion  to make up to 50%…

What makes hard workouts so effective — ScienceDaily

High-intensity interval training strengthens the heart even more than moderate exercise does. Now researchers have found several answers to what makes hard workouts so effective. “Our research on rats with heart failure shows that exercise reduces the severity of the disease, improves heart function and increases work capacity. And the intensity of the training is really importance to achieve this effect,” says Thomas Stølen, a researcher at the Norwegian University of Science and Technology (NTNU). Stølen and his colleague Morten…
