For the development of a Permanent Magnetic Synchronous Machine (PMSM), optimization of design variables, e.g. the size of an air gap, is performed. When applied to optical instruments in space environment, the motor has to be designed for ultra high vacuum (UHV) and cryogenic ... En savoir plus

Mobile robotics is an active research area, which is rapidly advancing thanks to a variety of technological developments in hardware and sensors. The operating environment and the tasks it must carry out are the main factors influencing the design of a climbing robot for industrial ... En savoir plus

The significance of electrification of industry increases with the growing influence of renewable electricity as a primary energy source on earth. In this sense, microwave heating is a well-established electricity-based and market-mature technology employed on the commercial scale in ... En savoir plus

Multiphysical simulation is a daily-used tool for loudspeaker design and engineering, however it is still a time expensive process that requires specific modeling capabilities. In order to increase engineering efficiency and to broaden the usage of multiphysical simulation, at ... En savoir plus

New methods of generating high-frequency magnetic fields of tens or even hundreds of millitesla at frequencies exceeding 2 MHz are allowing important new applications for induction heating. These include heating low conductivity ionic solutions in situations where electric or ... En savoir plus

This work explores the implications of wholly random and non-linear nanostructures on electromagnetic wave propagation within a multiphysics simulation environment. Showcased is a way to noticeably bypass the inaccuracies drawn from the linearity dependency of traditional simulation ... En savoir plus

Here we present a simulation for evaluation of novel obscurant candidates under high-energy laser (HEL) illumination. This approach incorporates thermal modeling into obscurant characterization, allowing for evaluation of the temperature increase of the candidate obscurants as well as ... En savoir plus

The Electromagnetic Signatures of Explosives Laboratory (EMXLAB) at the U.S. Department of Homeland Security, Science and Technology Directorate's Transportation Security Laboratory (TSL) supports the test and evaluation of millimeter wave imaging systems through the measurement of the ...
