The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). ... 詳細を見る
This paper proposes a FEM model for a segment of a nervous cell axon, which takes into account, through the so called Hodgkin-Huxley equations, the non linear and time varying dynamics of the membrane surrounding it. A combination with Maxwell equations is performed in a numerical ... 詳細を見る
A resonant MEMS sensor for viscosity and mass density measurements of liquids was modeled. The device is based on Lorentz-force excitation and features an integrated piezoresistive readout. The core sensing element is a rectangular vibrating plate suspended by four beam springs. The ... 詳細を見る
The self-ignition of tetrafluoroethylene (TFE) caused by contact with hot surfaces has been analyzed with the help of simulations performed with COMSOL Multiphysics®. The current study focuses on large-scale heated reactors for the industrial production of polytetrafluoroethylene (PTFE) ... 詳細を見る
The present article presents a method to redistribute the acoustic modes of a rectangular enclosure in the low frequency range using slit resonators. The objective of the present work is to compare different strategies of optimal design in order to determine the dimensions of the ... 詳細を見る
VRALA is the ideal candidate as an Adaptive Optics actuator at visible wavelengths. Its electric characteristics variations, suitable current commands, and an effective magnetic circuit geometry provide a 2 kHz correction bandwidth and a 25 mm actuator density. The magnetic core allows ... 詳細を見る
In this paper, PEM fuel cells with serpentine and interdigitated flow channel patterns were studied. The main objective was to analyze the influence of the flow channel design in the current distribution over the cell. A 3D isothermal model comprising the entire 5 cm² cell was developed ... 詳細を見る
The objective of this study is to determine the locations where liquid water accumulates at cathode gas flow channels, and the corresponding operating conditions. In such way it is possible to mitigate slug flow, responsible for channel blockage and hindering the diffusion of reactants ... 詳細を見る
Surface breaking cracks in conductive structures can be detected by conventional eddy current techniques. However, it is very difficult to detect inner layer defects in multilayered conductive structures either by conventional eddy current or ultrasonic methods. The transient/pulsed eddy ... 詳細を見る
The technology involved in high performance ultrasound imaging probes needs a reliable model to help in new projects development and performance simulations. To achieve a useful model, it is necessary to use correct values for all material parameters involved in the electro-acoustical ... 詳細を見る
