Potential improvements of the Coefficient of Performance (COP) were investigated for R-407C at cooling and heating conditions of a residential heat pump. The study used CYCLE-11, a semi-theoretical vapor-compression cycle model, which was upgraded to simulate cross-flow, counter-flow, and parallel-flow evaporator and condenser with no restrictions on specifying superheated vapor and subcooled l...

The fastest growing package types in the electronics industry today are Bottom Termination Components (BTCs). While the advantages of BTCs are well documented, they pose significant reliability challenges to users. One of the most common drivers for reliability failures is the inappropriate adoption of new technologies. This is especially true for new component packaging like BTCs. Obtaining re...

This thesis deals with the modeling, analysis and control of a novel brushless generator for wind power application. The generator is named as rotating power electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G). A great advantage of the RPE-BDFIG is that the slip power recovery is realized in a brushless manner. This is achieved by introducing an additional machine termed as...

Progress in high-performance computing (HPC) fundamentally requires effective thermal dissipation. At present this challenge is viewed in terms of two distinct architectural components: a computational substrate and a heat-exchange substrate. Typically these two components are viewed as performing conceptually different functions that are independent up to optimization constraints applied when ...

The superior properties of silicon carbide (SiC) power electronic devices compared with silicon (Si) are expected to have a significant impact on next-generation vehicles, especially hybrid electric vehicles (HEVs). The system-level benefits of using SiC devices in HEVs include a large reduction in the size, weight, and cost of the power conditioning and/or thermal systems. However, the expecte...

A new family of compact IGBT modules has been developed to bridge the gap between fully integrated IPM devices and basic IGBT modules. The idea of this new family was to give the designer the dynamic control offered by conventional IGBT modules while maintaining the reliability provided by integrated current and temperature sensing. The result is a new family of dual (half-bridge) modules with ...

An x-ray pixel array detector (PAD) capable of framing up to 1 kHz is described. This hybrid detector is constructed from a 3-side buttable, 128×128 pixel module based upon the mixed-mode pixel array detector (MMPAD) chip developed jointly by Cornell and Area Detector Systems Corporation (Poway, CA). The chip uses a charge integrating front end for a high instantaneous count rate yet with singl...

We have measured the cross-plane Seebeck coefficient of short period InGaAs/InAlAs superlattices with 5nm wells and 3nm barriers with different doping concentrations. Contrary to the behavior of conventional bulk III-V materials, the Seebeck coefficient did not decrease monotonically with increasing doping concentration. A detailed numerical calculation based on semi-classical Boltzmann transpo...

In the past 5 years, high brightness LEDs have begun to penetrate the lighting market. High brightness LEDs are attractive due to their high efficiency, very low power consumption and very long lifespans. This paper describes experiences in using white LEDs for lighting rural households in developing countries. The Light Up The World Foundation (LUTW) is an aid organization that has formed part...
