The aim of this work is to present a model capable to describe the behaviour of a thermal flow sensor under every physical aspect. A generic thermal flow sensor relates the flow properties with a variation in the temperature profile inside the device itself. Thus, it is locally heated ... En savoir plus

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines [1]. However, due to its low sensitivity the use of ... En savoir plus

Introduction: This study aims the optimization and sensitivity analysis of an existing device. A Secondary Ion Mass Spectrometer (SIMS) device is to be equipped with a high power laser in order to increase sputtering speed. The modified device must be capable of handling the increased ...

This article is the result of a hobby project. The article is going thru the iterative developing process of a claw pole machine. In this developing process, simulating the magnetic flux density and back EMF waveform have been used to validate geometrical changes to the machine. En savoir plus

Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... En savoir plus

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used ... En savoir plus

This paper presents a numerical analysis of magnetic devices, dipole, quadrupole and undulator and a THz Free Electron Laser (FEL) electron-beam recovery system. Free Electron Laser are an important source of coherent radiation being used in the study of chemical properties of ... En savoir plus
