The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors ... En savoir plus

Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... En savoir plus

Column Loudspeakers employ multiple drivers to get close to a radiating line source. A line source gives several acoustic advantages versus a point source, especially in highly reverberant environments. This property particularly has made column loudspeakers the preferred solution in ... En savoir plus

The aim of this paper is to determine the location of the “sweet spot” for a selected cricket bat commonly used in the sport. Knowledge of the “sweet spot” is important in delivering a shot that utilizes the optimal zone of the bat that corresponds to the maximum power of the stroke. A ... En savoir plus

Adaptive optics control using liquid filled membrane lens is based on the principle of deflection of polymeric membrane. Controlled deflection in membrane leads to controlled focal length. This enhances the focus tuning ability of the system at the same time make optical system compact ... En savoir plus

Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal ... En savoir plus

This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... En savoir plus

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics ...

Food dehydration processes assisted by high-power ultrasound (HPU) have become an efficient technology with a great potential in its implementation. To produce the desired effects in the samples, it is necessary that the dehydration system, composed by a HPU transducer and an ultrasonic ... En savoir plus

Wear in hydrodynamic journal bearings resulting from solid contact in the mixed friction regime becomes an increasingly prominent topic leading to the necessity of numerical wear evaluations. A numerical method tackling this topic based on Archard’s wear law is presented and applied on a ... En savoir plus
