Introduction Most current thermoregulation models represent the body in significantly simplified forms, e.g., cylinders or spheres. These simple geometries do not fully represent the complexity of bones, organs, etc. contained in the human body. Modern medical technologies allow for more ... En savoir plus
Liquid atomization relies on a variety of forces that disturb the surface of the liquid. In the case of flow-blurring (FB) atomization, turbulent structures are induced within the liquid channel to achieve this effect. It is known that the transition from the conventional flow-focusing ... En savoir plus
Lubricant oil is used to ensure proper functioning of industrial machinery such as turbines, gears, bearings and compressors. Oil analysis is used to detect and quantify the presence of wear metals and other contaminants in the lubricant of oil wetted systems, by sensing the change in ... En savoir plus
Curing concrete is best achieved by keeping it nearly saturated at an appropriate temperature until all the cement has fully reacted. However, when installing flooring materials that require low relative humidity (RH) in the concrete, the slab needs to dry as quickly as possible. ... En savoir plus
Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus
This communication reports on a numeric fluid dynamics simulation on a pipe flow model. The basic background is to determine the velocity of a flowing fluid in a pipe by using the Thermal Time-Of-Flight (TTOF) method on water. The visualization of the temperature and velocity ... En savoir plus
An automated design tool using COMSOL Multiphysics 3.5a and a genetic algorithm was developed to improve the performance of a MEMS resonant mass sensor. The device was comprised of a fixed-free poly-silicon micro-cantilever beam with electrostatic actuation and capacitive sensing. The ... En savoir plus
Interaction between the probe and a defect in eddy current non-destructive evaluation is studied. Evaluation of sensor signal response is the basis for the calculation. In this work a differential sensor is considered and the problem regarded here is problem 8 from the testing of ... En savoir plus
Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood interacts with vessel wall mechanically and chemically which modulates the plaque formation in blood vessel leading to coronary artery ... En savoir plus
This paper chalks out the design and performance of a piezo resistive surface micro machined circular diaphragm based pressure sensor. A structural deformation in the piezo resistive nano structure placed above the diaphragm will result in varied current density, which is in direct ... En savoir plus
