The Spark Plasma Sintering is a breakthrough way of elaboration of more or less complex shape materials from powder. This process allows the sintering of materials in few minutes compare to hours by conventional sintering. One of the main goals of the SPS modeling is to be able to ... En savoir plus

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... En savoir plus

Plasma spraying is one of the prominent technologies for wear, corrosion and high temperature resistant coatings. The coating quality is very important to increase the performance of the components as well as to protect the outer surface of the component from external environment. The ... En savoir plus

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. ...

Capacitive MEMS sensors offer high spatial resolution, sensitivity and good frequency response. In this paper, we present a circular membrane capacitive MEMS device that finds use both as capacitive micromachined ultrasonic transducer (CMUT) and pressure sensor. The MEMS device is first ...

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is ... En savoir plus

In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign ... En savoir plus

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance ... En savoir plus
