Integrating the entire system on a chip (SOC) is one of themain challenges formany researchers all over the world. One of the major breakthroughs toward achieving this goal has been the ability to manufacture multiple gate oxides for different requirements on the same chip. The most attractive of the techniques currently in the literature is the implantation of nitrogen in silicon, which can be...

The actual grinding result of ceramics has not been well predicted by the present mechanical models. No allowance is made for direct effects of materials microstructure and almost all the mechanical models were obtained based on crystalline ceramics. In order to improve the mechanical models of ceramics, surface grinding experiments on crystalline ceramics and non-crystalline ceramics were cond...

Title of Dissertation: On-Chip Thermoelectric Cooling of Semiconductor Hot Spot Peng Wang, Doctor of Philosophy, 2007 Directed By: Professor Avram Bar-Cohen Assistant Professor Bao Yang Department of Mechanical Engineering The Moore’s Law progression in semiconductor technology, including shrinking feature size, increasing transistor density, and faster circuit speeds, is leading to increasing ...

Introduction Load-carrying capacity of gears, especially the surface durability, is influenced by their tooth surface roughness in addition to their tooth profiles and tooth traces (Refs. 1 and 2). The harder the gears are, the smoother their tooth surfaces and the more accurately their tooth profiles should be finished in order to obtain high load-carrying capacity. Through research, the relat...

To ensure bearing reliability, it is traditional for compressor manufacturers to specify a minimum oil sump temperature difference above the saturated discharge temperature in a high-side compressor and suction temperature in a low-side compressor. This minimum oil sump temperature specification is, in essence, a surrogate measure of the minimum viscosity the compressor manufacturer reqtrires t...

in this study, effect of two genotype imputation strategies, relatedness between reference panel and test populations and minor allele frequency on imputation error rate were examined with using a stochastic simulated population. reference panel and test populations were composed of 1,000 and 500 individuals, respectively. individuals in the reference panel were genotyped with using a high and ...

purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thick...
