Symmetric multiprocessors (SMPs) connected with low-latency networks provide attractive building blocks for software distributed shared memory systems. Two distinct approaches have been used: the fine-grain approach that instruments application loads and stores to support a small coherence granularity, and the coarse-grain approach based on virtual memory hardware that provides coherence at a p...

Within the parallel genetic algorithm framework, there currently exists a growing dichotomy between coarse-pain and fine-grain parallel architectures. This paper attempts to characterize the need for fine-grain parallelism. and to introduce and compare three models of fine-grain parallel genetic algorithms (GAS). The performance of the three models is examined on seventeen test problems and is ...

to try and ascertain the relative importance of different soil properties for calibration. This approach has good Many empirical formulas relating TDR-measured permittivity (Ka) utility for finding simple and practical equations that can to volumetric water content ( ) have been presented owing to the lack of a robust and accurate physically derived model describing this be used to estimate . H...

The implementation of a low power logic based asynchronous circuit with the help of power gated logic. In asynchronous power gated logic (APL) circuit, each pipeline stage was incorporated with efficient charge recovery logic (ECRL) gate; handshake controller and partial charge reuse (PCR) mechanism. The main objective was, to provide a new lower power solutions using power gating (PG) for very...

This investigation was undertaken to determine the factors influencing electrokinetic remediation of soils from petroleum pollutants. The remediation method was applied in two versions: (i) static and (ii) flowing, when a sample was washed with leaching solution. It was found that all the soils studied can be purified using this technique. It was also observed that the mineral and grain-size co...

Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...

in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...

Coarse-grain models are becoming an increasingly important tool in computer simulations of a wide variety of molecular processes. In many instances it is, however, desirable to describe key portions of a molecular system at the atomic level. There is therefore a strong interest in the development of simulation methodologies that allow representations of matter with mixed granularities in a mult...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

For the French ancient rail track, owing to effect of traffic loadings, an interlayer was naturally created due interpenetration ballast grains and subgrade fine soil. Under rainfall/evaporation, water content soil can vary, affecting its dynamic properties such as resilient modulus damping ratio. In order investigate on ratio soil, a series cyclic triaxial tests were carried out, following mul...
