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 ...
High-intensity discharge (HID) lamps are highly-efficient light sources with many applications. Depending on the dimensions of the electrode, lamp current, and waveforms, the plasma may attach to the cathode in a diffuse mode, that covers the electrode tip surface, or a localized mode where heating and current transfer occur in a local region of the electrode surface. The localized mode is ...

The control of the flux within continuous casting systems used in the metallurgical field can be obtained through the application of electromagnetic. The model here has been solved through a linear time-harmonic solver. The results of the electromagnetic model have then been applied to the fluid-mechanics model through volume Lorentz forces.

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 ...
