The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has been conducted in the area of MEMS cooling devices, taking advantage of the increased heat transfer ...

Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs exclusively use Solid Oxide Fuel Cells with some developments in high temperature polymer electrolyte membranes ...

We have developed optically driven micropumps by manipulating microstructures using optical tweezers. In this study, we proposed and developed a novel manipulation method of a single metallic nanowire. In this method, dynamic optical vortex is used not only for manipulating a metallic nanowire in the focal plane, but also for grasping it along the optical axis. This method will be used for ...

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of compact material located in the upper layers because the stress propagation generated by the extraction ...

The production model in the COMSOL Multiphysics® software makes use of the most up-to-date PIE data, material property inputs, and modeling methodology. The fully coupled thermo-mechanical equations are solved over the entire domain, significantly increasing the degrees of freedom required for a solution, in addition to several other improvements in the computational methodology of the model. ...

Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to inform the driver of a car with a connected trailer about vertical and trailing loads. This helps to ensure a ...

The effect of metallization thickness on planar transmission lines plays an essential role in microwave integrated circuits and thin film technology, especially in the propagation characterization and the electric field distribution in the structures. The objective of this paper is to consider the planar transmission lines with finite thickness not penetrating and penetrating into isotropic ...

A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics 3.4 code has been adopted to solve the combined thermal and electromagnetic problem in order to compare the ...

We demonstrate the accuracy of the Finite Element Method (FEM) to characterize an arbitrarily shaped crossed-grating in a multilayered stack illuminated by an arbitrarily polarized plane wave under oblique incidence. To our knowledge, this is the first time that 3D diffraction efficiencies are calculated using the FEM. The method has been validated using classical cases found in the literature. ...

We present a mechanical model a growing spherical shell suitable for predicting the evolution of a Saccular Cerebral Artery Aneurysms (SCAA). It relies basically on the Kröner-Lee decomposition, used to describe the interplay between the current and the relaxed configuration of body elements. Rupture or stabilization of a SCAA are the end effect of a number of biological mechanisms, still poorly ...
