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

Liquid transport in lab-on-a-chip (LOC) devices occurs through a microchannel that uses an electroosmotic flow actuation mechanism. This method has a plug-like velocity profile, which is ideal in species transport and in wall-bounded reactions. Under substantial joule heating, it is not ... 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

Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... En savoir plus

In this paper, the influence of carbon nanotube (CNT) in a metal matrix on the buckling behavior of the resulting nanocomposite plate is studied. The Young's moduli of CNT reinforced nanocomposite are predicted first using the representative volume element (RVE) method. CNTs are ... 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

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... En savoir plus

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 ... En savoir plus
