Electric pulses precisely shape 3-D-printed metal parts

Professor Dirk Bähre (l., here with Stefan Wilhelm from his research group) and his research team at Saarland University have developed a non-contact method of transforming metal parts fabricated by a 3D printer into high-precision technical components for specialist applications. The novel method enables them to process parts made from strong, lightweight metals to produce precision-finished components with complex geometries and dimensional tolerances of a few thousandths of a millimeter. The team of manufacturing technologists combine metal 3D printing and…

Are Face Masks in Your Manufacturing Future?

At a time when a company’s current product line isn’t selling, a good business leader will look for ways to repurpose their equipment to produce what is in demand. But, for most manufacturers, having the capability to retool is an exception, not the rule. Manufacturers considering a shift to making personal protective equipment (PPE), complex machinery such as ventilators and other COVID-19-related gear are discovering how difficult switching production can be. The core reason tackling a new product is so…

Designing and Maintaining Optimized Networks for Dynamic Wi-Fi Environments

Download this article in PDF format. In the fast-changing Internet of Things (IoT) world, there’s no shortage of possibilities for smart-home devices. For developers, that means more design challenges than ever before. Projects, for example, can no longer take years to move from concept to market. Rapid prototyping enables an IoT company to consider client input, needs, and wishes, and quickly demonstrate what their solution would look like. It involves minimal development time and costs while providing the needed flexibility…

The Million-Mile Battery Club | Electronic Design

Most electric car batteries today last 100,000 to 200,000 miles before replacement, while most current gas-engine cars only last 150,000 miles before joining the scrap heap. So why are EV makers seek a million-mile battery? The answer is they are preparing for what comes next: Allowing EV batteries to have second lives in stationary grid storage systems by enabling a vehicle to send power back into the grid via a bidirectional charger. With a battery capable of lasting a million…

Create Your Personalized TV Guide with Friendspire

The quarantine doesn’t seem to be anywhere near its end and it is obvious that you have already watched ‘Friends’ and ‘The Office’ for the millionth time by now. While classics like these never leave your side, you do need a change from something new every now then. But how will you know whether that new show on werewolves is as good as Teen Wolf or whether the new season of Money Heist won’t be a waste of time? While…

Can copying your friends help you achieve your goals? — ScienceDaily

Consumers often struggle to achieve self-set life improvement goals, but what if deliberately emulating the successful strategies used by their friends could help them? A new paper published in the Journal of the Association for Consumer Research shows that encouraging people to find and mimic exercise strategies used by their friends increases the amount of time people spent exercising relative to receiving an exercise strategy passively. In the study, Katie S. Mehr, Amanda E. Geiser, Katherine L. Milkman, and Angela…

Past Participants Tout Benefits of REU Program

REU Program students study consumer networking. Students from across the country will spend the next 10 weeks developing consumer networking skills. It’s part of a Research Experiences for Undergraduates, or REU, program at Mizzou Engineering funded by the National Science Foundation. And for some, it’s life changing. The REU program gives undergraduates an opportunity to conduct research on fundamental topics in consumer networking. Students work with multi-disciplinary experts. At the end of the program, they develop an innovative prototype that relates…

NIST Refining Laser-Power Measurement Over 20 Orders of Magnitude

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range. Still, that’s only the beginning of the truly challenging part of the spectrum range. Laser-sourced optical power is even more difficult to measure, due to its wide spectrum (IR, visible, and UV), sensors with limited spectral sensitivity, and wide dynamic range. Nonetheless, as optical components and optoelectronics become increasingly critical parts of…

NIST formula may help 5G wireless networks efficiently share communications frequencies

NIST engineer Jason Coder makes mathematical calculations for a machine learning formula that may help 5G and other wireless networks select and share communications frequencies efficiently. Credit: NIST Researchers at the National Institute of Standards and Technology (NIST) have developed a mathematical formula that, computer simulations suggest, could help 5G and other wireless networks select and share communications frequencies about 5,000 times more efficiently than trial-and-error methods. The novel formula is a form of machine learning that selects a wireless…

DEPC Recognized by National Academy of Inventors

Tojan Rahhal (left), Assistant Dean for Inclusive Excellence and Strategic Initiatives, poses with members of the Engineering Diversity Collaborative Evonne Weeden, Brooke Flynn, Kate Clemens, Victoria Sanchez, Jacqueline Miller, Andrew Guardia and Samantha Sample, along with Hilary Mueller, Director of the Office Diversity and Outreach Initiatives, during a break at the Diverse Engineering Professionals Conference last fall. The College of Engineering established the Diverse Engineering Professionals Conference (DEPC) in 2017 to recognize diversity organizations and diverse students while promoting the…
