ABB Semiconductors increased the lifespan of an insulated-gate bipolar transistor (IGBT) using multiphysics simulation. IGBT modules are used in high-power electrical systems and are subjected to repeated electrical, thermal, and mechanical loading. The ABB team explored different wire ... Per saperne di più
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 ... Per saperne di più
Researchers at Radiotelevisione Italiana (RAI) are optimizing circularly polarized antenna designs for recording live sporting events, like the prestigious cycling event Giro d'Italia in Italy, with minimal service interruptions. To do so, they turn to multiphysics simulation. Per saperne di più
Traditional power boxes are bulky and too large. To design a power box that is more space-conscious, modular, and ready for implementation in smart cities, while also ensuring structural and thermal integrity, Raychem RPG is using multiphysics simulation. Per saperne di più
Deep-space telescopes require ultrasensitive detectors and calibration to pick up weak far-infrared signals. The SpicA Far-InfraRed Instrument (SAFARI), an infrared camera that will fly aboard the Space Infrared Telescope for Cosmology and Astrophysics (SPICA), has sensors that measure ...

The environments in which sensors are most integral are often the most harsh and unforgiving, such as vacuum chambers, the ocean floor, and petroleum reservoirs. Traditional sensing techniques are not ideal in these applications, whereas optical fiber sensors can provide a versatile ... Per saperne di più
Engineers and physicists at CERN go to great lengths to ensure that the high-power superconducting magnets that maintain the circular trajectory of particles inside the Large Hadron Collider (LHC) do not revert to a resistive state, an event known as a quench. To understand and prevent ... Per saperne di più
In addition to surviving normal winters, a strong building must be able to survive the worst winters expected in a 50-year period. When moisture and contaminants enter concrete foundations, they create the risk of cracking or other structural damage once the soil or foundation freezes. ... Per saperne di più
