The Poisson equation, as implemented in the COMSOL Multiphysics® AC/DC module, solves for the electrostatic potential due to general charge distributions subject to various boundary conditions, very often Dirichlet conditions of constant potential at conductor surfaces. When both the ... En savoir plus

MEMS gyroscopes are typically challenging to model due to the variable length scales present in the device (typically 1000:1) and because the devices themselves are highly sensitive to both environmental and manufacturing process induced deviations from the ideal geometry. In this paper ... En savoir plus

In the manufacturing of high voltage electrical equipment, an important step to guarantee a right dielectric design can be carried out through the prediction of a possible occurrence of the corona effect or, in the worst case, of dielectric breakdown, preferably in early stages. For this ... En savoir plus

Laser surface texturing has emerged as a promising texturing technique due to properties such as excellent repeatability, non-contact process, the ability to achieve small-size features and high-quality finishing. The work described here is part of the H2020 research program called SHARK ... En savoir plus

This study is focused on the optimization of a- YBa2Cu3O7-x (YBCO) based bolometer working above 77 K. The temperature distribution on the superconductor surface and the temperature profile through the whole system (bolometer plus plate with heaters) were studied at the working point ...

Pulsed Electric Field (PEF) technology is gaining much attention in the food industry, as it offers unique advantages in terms of food safety, preservation of the organoleptic and nutrients properties, and low energetic requirements. Winemaking processes, in particular, can greatly ... En savoir plus

Wireless capsule endoscopy (WCE) is a less invasive alternative to conventional endoscopy. In WCE, a patient swallows a small capsule equipped with a camera, allowing a video of the gastrointestinal tract (GIT) to be captured for diagnostic analysis. To ensure an accurate diagnosis and ...

Abstract High-voltage relays currently used for deep sea applications must be designed for extreme underwater conditions. So, pertinent materials used, and the design procedures adopted are novel, innovative but expensive. Alternatively, the existing high-power electric switches, relays ... En savoir plus
