Parallel Constrained Delaunay Mesh (PCDM) is a 2D adaptive and irregular meshing algorithm. In PCDM one can explore concurrency using three different levels of granularity: (i) coarse-grain at the sub-mesh level, (ii) medium-grain at the cavity level and (iii) fine-grain at the element level. The mediumand fine-grain approaches can be used to improve the single-processor performance of coarse-g...

A recent trial found that the presence of coarse soil in fine soil increased nutrient uptake by two plant species (Smaill et al., 2014). To determine if the additional nutrient uptake was derived directly from the coarse soil, the changes in coarse soil nutrient stocks were assessed. In most cases nutrient stocks increased, despite being associated with greater plant nutrient uptake. This sugge...

This paper presents a systematic approach to treating the interfaces between the localized (fine grain) and peripheral (coarse grain) domains in atomic scale simulations of crystalline solids. Based on Fourier analysis of regular lattices structures, this approach allows elimination of unnecessary atomic degrees of freedom over the coarse grain, without involving an explicit continuum model for...

While the dataaow execution model can potentially uncover all forms and levels of parallelism in a program, in its traditional ne-grain form, it does not exploit any form of locality. Recent evidence indicates that the exploitation of locality in dataaow programs could have a dramatic impact on performance. The current trend in the design of dataaow processors suggest a synthesis of traditional...

Multiscale methods are becoming increasingly promising as a way to characterize the dynamics of large protein systems on biologically relevant time-scales. The underlying assumption in multiscale simulations is that it is possible to move reliably between different resolutions. We present a method that efficiently generates realistic all-atom protein structures starting from the C(alpha) atom p...

this paper describes the results of a study which was primarily directed to the determination of geotechnical properties of fine and coarse grain soils stabilized by lime obtained from taleghan, northwest of tehran to assess its suitability as construction material. soils were treated with lime mixtures in various portions between 3 to 9 percents by weight. the samples were cured for different ...

MOTIVATION The recent development of methods for modeling RNA 3D structures using coarse-grain approaches creates a need to bridge low- and high-resolution modeling methods. Although they contain topological information, coarse-grain models lack atomic detail, which limits their utility for some applications. RESULTS We have developed a method for adding full atomic detail to coarse-grain mod...

In this paper, we propose a hardware/software partitioning method for improving applications’ performance in embedded systems. Critical software parts are accelerated on hardware of a single-chip generic system comprised by an embedded processor and coarse-grain reconfigurable hardware. The reconfigurable hardware is realized by a 2-Dimensional array of Processing Elements. A list-based mapping...

The aim of this study is to evaluate the biodegradation performance of phenol in a fixed biofilm developed in sand soil media. The parameters which had been studied and may influence the biodegradation were: a) the grain size of sand, b) the rate of flow, and c) the initial phenol loading. Laboratory scale of two columns with inner diameter of 5 cm was used. The first column was packed with fin...

While the chip multiprocessor (CMP) has quickly become the predominant processor architecture, its continuing success largely depends on the parallelizability of complex programs. In the early 1990s great successes were obtained to extract parallelism from the inner loops of scientific computations. In this paper we show that significant amounts of coarse-grain parallelism exists in the outer p...
