Seeking Out Electrical Arcing Regions in Satellite Systems

Vasily Kozhevnikov, Institute of High Current Electronics, Russia

Space is the epitome of an unpredictable and harsh environment. These conditions are near impossible to replicate via experimentation, making it exceedingly difficult to study the behavior of space-borne devices. To circumvent this issue, numerical simulation is often employed to ... 詳細を見る

Accelerating Custom Capacitor Design with Simulation Apps

Sam Parler, Cornell Dubilier Electronics, USA

When a component is as ubiquitous as a capacitor, its design process needs to allow for a lot of customization. This is because their large variety of applications, ranging from fighter jets and radar to wind turbines and solar energy, can entail distinct and demanding requirements. ... 詳細を見る

Revving up Electrohydraulic Power Steering with Virtual Prototyping

Feng Qi, FZB Technology, USA

In the automobile industry, the only thing faster than the cars that are produced is their design cycle. Validation and physical prototyping can be expensive and time consuming, but getting as close as possible to a final design before transitioning from virtual prototyping can speed up ... 詳細を見る

Engineering Perfect Puffed Snacks

Tushar Gulati, Ashim Datta, Cornell University, USA

The production of puffed rice, like many other types of food, is incredibly complicated and involves multiple interconnected types of physics: mass transport, phase transitions, and plastic deformation. Professor Ashim Datta of Cornell University is leading a team to simulate the puffing ... 詳細を見る

How Fast Do Elevated Temperatures Reach the Cell Interior?

Gerd Liebig, Pamina Bohn, NEXT ENERGY EWE Research Centre for Energy Technology, Germany

Lithium-ion batteries, which have a tendency to degrade at high temperatures, must adhere to stringent regulations guaranteeing their ability to withstand operating temperature fluctuations. Researchers at NEXT ENERGY used heat transfer modeling to study whether high welding temperatures ... 詳細を見る

Nuclear-Safety-Related SQA Procedure Automation with Custom Applications

James D. Freels, Michael W. Crowell, Oak Ridge National Laboratories, USA

In an environment as highly regulated and potentially dangerous as the nuclear industry, software quality assurance (SQA) compliance standards are rigorous. Part of the compliance process entails verification that local software installations perform as the developer intended. At Oak ... 詳細を見る

On the Cutting Edge of Hearing Aid Research

Brenno Varanda, Knowles Corporation, Illinois, USA

Nearly 20% of the United States population has some degree of hearing impairment. Despite the relative inconspicuousness and perceived simplicity of hearing aids, their development involves complex, time-consuming, and computationally expensive research. The hearing aid industry is in ... 詳細を見る

Music to Your Ears: New Transducers Meet Electrostatic Headphones

Brett Marmo, Xi Engineering; Martin Roberts, WAT, UK

Electrostatic transducers offer enhanced clarity, less distortion, and a wider bandwidth than transducers in conventional dynamic-driver headphones, but they are only seen as high-end alternatives. The precise manufacturing requirements make electrostatic transducers prohibitively ... 詳細を見る

Manipulate and Control Sound: How Mathematical Modeling Supports Cutting-Edge Acoustic Metamaterials Research

Steve Cummer, Electrical and Computer Engineering Department, Duke University, USA

Researchers at Duke University are using numerical modeling to develop metamaterial structures for acoustic cloaking. Steve Cummer, professor of electrical and computer engineering, explained that the acoustic metamaterial designs are optimized through numerical simulations, which are ... 詳細を見る

Let There Be Light: A Brighter Future for OLEDs

Leiming Wang, Konica Minolta Laboratory, USA

As the demand for lightweight and flexible electronics continues to increase, so does the demand for lightweight and flexible light sources. Organic LEDs (OLEDs) have garnered tremendous interest because of their inherent elasticity, but suffer from a lack of brightness and efficiency. ... 詳細を見る
