Thomas Dreeben received his B.A. in Philosophy and Mathematics in 1985, and his Ph.D. in Mechanical Engineering in 1997, both from Cornell University. He has worked in automotive fuel systems at Ford Motor Company, and in turbulence at Sandia National Laboratories. He currently works in ... En savoir plus

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality [3]. PV researchers need an accessible and versatile simulation tool to optimize existing ... En savoir plus

In semiconductor manufacturing, effective cleaning of structures with liquid is one of the most important and potentially difficult process steps. It is important because it remains the cheapest and most cost-effective method to remove particles and residues from the structures in order ... En savoir plus

In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is ... En savoir plus

With the ever changing energy requirements & demand for better communication links across the planet, subsea umbilical & cable requirements are becoming more stringent. Where longer service life at a lower cost is now expected from manufacturers. In addition to this, with the ... En savoir plus

RF propagation modelling in (30 – 1000 MHz) SAR region for predicting the location and intensities of constructive interference patterns within rectangular confined spaces using waveguide theory and ray tracing techniques. En savoir plus

This work enunciates the principles of SAW design from a physical perspective, examining the standard engineering modelling assumptions in some detail. An integral form analytical expression based on 2D elastic isotropic theory is validated against a COMSOL Multiphysics® simulation, ... En savoir plus

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... En savoir plus

INTRODUCTION: Active cooling systems represent a possible solution to the electronics overheating that occurs in downhole tools operating on wireline, a cabling technology used to remotely control the downhole devices during oil and gas well interventions, in high temperature wells (150 ...

A new experimental device has been developed in order to characterize the phase change material (PCM) thermal properties (thermal conductivity k, sensible and latent heat thermal energy storage, cp and Lf) in the solid phase, during the solid-liquid transition and in the liquid phase. It ... En savoir plus
