High-Temperature Superconductors (HTS) can be superconducting in liquid nitrogen (77 K), holding immense promises for our future. They could enable disruptive technologies such as nuclear fusion and power applications. In a power system, for instance, high short-circuit currents can ... En savoir plus
The era of electrical transportation is here and this includes the aviation sector. However, the electrification of airplanes is setting new challenges due to the system operating conditions and ambient conditions during flight which are highly variable. DC electrical systems are ... En savoir plus
In modern days one of the biggest challenges is to have a special connector for very high current power supply which shouldn’t exceed the rating temperature of 90°C at full load. This main challenge it to design special connectors of aluminum (Al). In this study, a new approach is ... En savoir plus
Residual Gas Analyzers (RGA) are often used to measure background gases and contaminations in vacuum systems. An ionizer is used to ionize gas molecules and these ions are accelerated and focused by an electrical field from the ion source to form an ion beam. The ions can be ... En savoir plus
There is an increasing demand for aerosol devices from E-cigarettes to drug delivery devices with precise dosage. [1][2] The aim of this article is to investigate a Poly-Si micro heater in a vapor generator device. In order to calculate the amount of vapor production, temperature ... En savoir plus
Abstract. A Laser Focusing system (LFS) focuses a single laser beam (single Channel) or multiple laser beams (multi - channel) onto a surface (Specimen). The general motive of a LFS is to focus a train of brief pulses or a continuous beam of light onto a Specimen which heats up its ... En savoir plus
Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus
Investment casting is practised in both the automotive and aerospace industries, to produce casted components where a high-quality surface finish is critical. Vacuum induction melting (VIM) and direct pouring into an investment casting shell mould is an advantageous manufacturing ... En savoir plus
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
