This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... En savoir plus
Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental ... En savoir plus
Ultrasonic sensors are commonly used for a wide variety of non-contact presence, proximity or distance measuring applications in industry, especially the automotive branch. This paper shows how the radiation properties of bending-type ultrasonic transducers with rotational symmetry ... En savoir plus
Transmission-line transducers are used for the measurement of absorption and reflection of different materials, such as: liquids, granular medium, and ground. A simplified methodology for calculation of scattering parameters of such transducers is presented. The transducer cell is ... En savoir plus
Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal part ... En savoir plus
Otoacoustic emission (OAE) tests provide an objective examination of the cochlear function. However, the validity of OAE tests is affected negatively by calibration errors. This report sheds light on the evanescent waves arising at the interface between the OAE probe and the ear canal, ... En savoir plus
When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... En savoir plus
Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and ... En savoir plus
Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... En savoir plus
A research team at FSU CAPS is developing a novel fast disconnect switch based on a piezoelectric actuator for use in next-gen electric power distribution systems. COMSOL Multiphysics® software was used to optimize geometry and material selection of the disconnect switch. Current ... En savoir plus
