Micromilling is one of the preferable micro-manufacturing process, as it exhibits flexibility to produce complex 3D micro-parts. The cutting forces generated in micro end milling can be attributed for tool vibration and process instability. If are not controlled below critical limits, may lead catastrophic failure tool. Cutting force has a significant role decide surface roughness. Therefore ac...

Lockup-free caches in conjunction to non-blocking processor loads have been proposed to hide miss latencies in high performance processors. One problem with current approaches is the increased complexity of the processor and of the cache controller due to non-blocking. In this paper, we introduce a simple mechanism to support non-blocking loads and a lockup-free cache. A modified SPARC architec...

It is widely known that the Translation Lookaside Buffer (TLB) plays an important role in the address translation mechanism from virtual addresses to physical addresses. If any misses occur, the performance of the processor will seriously degrade. In order to reduce such misses, some methodologies are proposed. Some designs try to improve the associativity or sizes to reduce the conflict or cap...

PURPOSE The purpose of the study was to determine if increasing radiologist reading speed results in more misses and interpretation errors. METHODS We selected a sample set of 53 abdomen-pelvis CT scans of variable complexity performed at a teaching hospital during the study period. We classified the CT scans into 4 categories based on their level of difficulty, with level 4 representing the ...

Control systems can show robustness to many events, like disturbances and model inaccuracies. It is natural speculate that they are also robust sporadic deadline misses when implemented as digital tasks on an embedded platform. This paper proposes a comprehensive stability analysis for control subject misses, leveraging new formulation describe the patterns experienced by task under different h...

This paper analyzes the behavior of high-performance web servers along three axes: packet rate, number of connections, and communication latency. Modern, high-performance servers spend a significant fraction of time executing the network stack of the operating system—over 80% of the time for a web server. These servers must handle increasing packet rates, increasing numbers of connections, and ...

background von hippel-lindau (vhl) disease is a hereditary, autosomal dominant syndrome which is manifested by a range of different benign and malignant tumors. this disease can present with different clinical presentations such as; retinal angioma (ra), hemangioblastoma (hb) of the central nervous system (cns), pheochromocytoma (pheo), and epididymal cystadenoma. tumors are usually accompanied...

Computer systems have enjoyed an exponential growth in processor speed for the past 20 years, while main memory speed has improved only moderately. Today a cache miss to main memory takes hundreds of processor cycles. Recent studies have demonstrated that on commercial databases, about 50% or more of execution time in memory is often wasted due to cache misses. In light of this problem, a numbe...

As the number of transistors that can be integrated onto a single chip continues to increase exponentially, a growing challenge is modeling performance with reasonable accuracy in the early stages of processor design. While methodologies for execution driven simulations are well understood, comparatively little is known about how to develop accurate analytical models. Processor architects in in...

Dynamic von-Kármán plate models consist of three coupled non-linear, time-dependent partial differential equations. These equations have been recently solved numerically [Kirby, R., Yosibash, Z., 2004. Solution of von-Kármán dynamic non-linear plate equations using a pseudo-spectral method. Comp. Meth. Appl. Mech. Eng. 193 (6–8) 575–599 and Yosibash, Z., Kirby, R., Gottlieb, D., 2004. Pseudo-sp...
