Grinding Wheel Loading with and without Vibration Assistance

Introduction Due to its tool structure and composition, the grinding operation is considered the best machining process in the manufacture of brittle materials like ceramics. A grinding wheel distributes wear over many cutters and is capable of replenishing itself. However, the condition of the grinding wheel constantly changes as grits wear and chips accumulate in the spaces between grits. The...

Unfolding grain size effects in barium titanate ferroelectric ceramics

Grain size effects on the physical properties of polycrystalline ferroelectrics have been extensively studied for decades; however there are still major controversies regarding the dependence of the piezoelectric and ferroelectric properties on the grain size. Dense BaTiO3 ceramics with different grain sizes were fabricated by either conventional sintering or spark plasma sintering using micro-...

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...
