Loss-on-ignition (LOI) is an important thermo-chemical property test for many foundry materials. Applications include new sands, green sand systems, chemically bonded cores and molds, sand additives, and reclaimed sands. LOI has been an important quality control measure carried out off-line. The AFS-defined LOI test uses a muffle furnace that is time consuming, often requiring three hours; a mo...

in this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of iran. four stations in khuzestan- abadan, hosseyneh, mahshahr, and shushtar- are analyzed to determine the potential of wind power generation in this province. from the primary evaluation and by determining mean wind speed and also the weibull funct...

This study presents global 3-D electrical conductivity models of the world ocean and marine sediments. Electrical was calculated by invoking Equation State Seawater (TEOS-10) with temperature salinity data retrieved from World Ocean Atlas a series high-resolution regional climatology sets. The resolution atlas varies between 0. globally. sediments estimated using compaction thermal gradient con...

data grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. the heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. most existing scheduling algorithms in grids only focus on one kind of grid jobs which can be data...

abstract— data grids are an important branch of gird computing which provide mechanisms for the management of large volumes of distributed data. energy efficiency has recently emerged as a hot topic in large distributed systems. the development of computing systems is traditionally focused on performance improvements driven by the demand of client's applications in scientific and business ...

Background: In conventional radiation therapy, regarding normal tissue tolerance, the treatment of bulk tumors is one of the remaining challenges. Grid Radiation Therapy (GRT) is a technique to deliver high doses, approximately 15 – 20 Gy per fraction, to several small volumes located in a large radiation field. This can be performed using a grid block. The current work has concentrate...

the favorable gains gleaned from the provision of pre-task planning time (ptp) have struck a chord with sla researchers as they try to manipulate task features to promote language production and development. in a similar vein, the present study is a two-fold attempt to first compare the effect of the length of pre-task planning time on discourse-analytic measures in narrative written production...

Introduction: Radiation-induced bystander effect (RIBE) is a well-known response associated with the induction of radiation effects in non-irradiated cells via signaling of hit ones. As this so-called phenomenon has been largely investigated in low dose levels, few studies focused on higher dose levels such as grid therapy. Grid therapy or spatially fractionated gri...

Abstract In recent years, wind energy, as a ubiquitous, easy-to-capture cost-effective clean is accounting for sharp increase in the installed capacity of China’s new energy grid. However, its stochastic volatility has always brought challenges to generation scheduling farms. To better optimize management level farms and improve stability power grid connection, this paper proposes design foreca...
