Ultra-Smoothness Grinding of Fine Ceramic by Coarse Grain Size Diamond Wheel

Microstructure Characteristics of Ultra-fine ZrO2-Y203 Ceramic Powders*

Yttria-doped zirconia powders" with an extremely small crystallite size (8 nm) and a narrow size distribution have been prepared by gel precipitation methods. Precipitation of an alkoxide solution in water ("alkoxide" synthesis) results in weaker agglomerates when compared with a precipitation of a metal chloride solution in ammonia ("chloride" synthesis). Both types of agglomerate are fracture...

Deep Jam: Conversion of Coarse-Grain Parallelism to Fine-Grain and Vector Parallelism

A number of computational applications lack instruction-level parallelism. This loss is particularly acute on sequences of dependent instructions on wide-issue or deeply pipelined architectures. We consider four real applications from computational biology, cryptanalysis, and data compression. These applications are characterized by long sequences of dependent instructions, irregular control-fl...

Adaptive Granularity Transparent Integration of Fine Grain and Coarse Grain Communications

The granularity of sharing is one of the key components that a ect the performance in distributed shared memory DSM systems Providing only one or two xed size granu larities to the user may not result in an e cient use of resources Providing an arbitrarily variable granularity increases hardware and or software overheads Moreover its e cient implementation requires the user to provide some info...

Effect of Cyclotrimethylenetrinitramine on the WetSynthesis of Ultra-nanocrystalline Diamond

The Ultra-nanocrystalline diamond (UNCD) was synthesized by the detonation of a high explosive mixture in water confinement. The presence of a diamond phase was revealed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). X-ray line broadening (XRLB) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. The micro st...
