Scanning field emission microscopy (SFEM) is a technique based on Topografiner [1] and Scanning Tunneling Microscopy (STM) [2] technologies. In this work, we do SFEM experiments to measure the electrons emitted by a sharp tungsten tip once they are back-scattered by a W(110) surface with ... En savoir plus
A suspension composite insulator has been designed for the HVDC energization of an overhead line supported by the L7 tower of Scottish and Southern Energy (SSE). It has been chosen to apply a pole to ground voltage of 216 kV for a triple symmetrical bipolar scheme. To verify the ... En savoir plus
The aim of this work is to compute the mechanical stresses in power transformer winding due to an external short-circuit event. This event can be considered as one of the most demanding load conditions and many details such as material type, type of constraints, winding geometry ... En savoir plus
Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... En savoir plus
In this work, we present a methodology for the design and analysis of a double-sided linear induction motor for a scaled Hyperloop pod in COMSOL Multiphysics®. The key aspects are discussed as follows: Formulation of problem and simulation environment: The goal is to design a Double ... En savoir plus
EDF Energy use an Eddy Current Inspection Tool (ECIT) to test the properties of graphite bricks in the cores of UK Advanced Gas-cooled Reactors (AGRs). The tool comprises a coil containing an alternating current which generates a magnetic field, inducing eddy currents within the nearby ... En savoir plus
With the rapidly increasing usage of portable electronic devices and wireless communication technology, generation and propagation of electromagnetic energy are becoming one of the major concerns, not only because it affects the functionality and integrity of the electronics and their ...

ZF-Friedricshafen AG is one of the biggest supplier of Automatic Gear Shifters for the modern cars and ZF-Automatic Gear Shifter needs sensing of five or seven positions (e.g. P, R, N, D, S) and (M+, M-) etc. Hall Sensors and Inductive Sensors are two automatic choices for such ... En savoir plus
The construction of a superconducting aircraft motor demonstrator is underway under ASuMED project. Magnetized stacks of commercial superconducting tapes will be applied in a rotor in place permanent magnets. The rotor will be cooled with liquid hydrogen down to approximately 20K to ...

The next step in the evolution of the metal sector of Additive Manufacturing and especially for Laser based Powder Bed Fusion is the production of multi-material components as shown by [1]. Therefore, the powder application module must be able to selectively arrange different powders in ... En savoir plus
