This work describes the study of a thermal actuator and modifications to the materials employed in order to decrease power consumption and implementation costs. For this study, we worked on improving the thermal actuator described in the work of T. Ebefors. The criteria for choosing the new materials were lower power consumption, commercial availability, and ease processing. The thermal actuator ...

This paper presents the fast computational and modeling of multiconductor transmission lines interconnect in non-homogenous multilayered dielectric media using the finite element method (FEM). We illustrate the potential distribution of the multiconductor transmission lines for the models and their solution time. We compared some of our results of computing the capacitance matrix with method of ...

In this communication, we deal with the numerical simulation of Voltage Operated ionic Channels (VOC) in Bio-Electronics. Suitable functional iteration techniques for problem decoupling and finite element methods for discretization are proposed and discussed. Model and computational procedures are validated in the simulation of a real-life VOC under several working conditions.

Sensing electrodes array model of 3-Dimensional ERT/ ECT dual modality is established by using the software COMSOL. According to the uniformity of sensitivity field distribution, the correlation coefficient and the reconstructed image space resolution, the ECT/ERT dual modality sensing electrode arrays are optimized. Experimental results show that the optimized sensing electrode array of the ...

Partial differential equations which exhibit solutions that are spatial temporal patterns are often found in biological and chemical systems, e.g. when describing pattern formation in reaction-diffusion systems.Special classes of such patterns are relative equilibria and relative periodic orbits, which are solutions that in an appropriately co-moving frame of reference are stationary and ...

A microfluidic device for performing multiplexed cell bioassays has been successfully developed. The device takes advantage of laminar flow and hydrodynamic focusing in order to selectively load cells into various culture chambers and address cells with pharmacological agents. Both computational fluid dynamics (CFD) simulations and fluorescence microscopy illustrate how fluid flow can be ...

This paper describes the automatic optimization of an electromagnetic actuator using a genetic algorithm. The actuator modeled here is dedicated for charge changing valve actuation in internal combustion engines. In the first step of the simulation, several operating points are calculated using the script language of COMSOL Multiphysics. In order to reduce computation time, only one segment of ...
