The long and large-diameter uncharged hole-boring (LLB) method is a cut-blasting used to reduce vibration induced by blasting. This typically involves creating an hole with 382 mm diameter drilling 50 m in the tunnel excavation direction at time. reported provide relatively good reduction high blasting efficiency through short compared traditional cut methods. In this study, advanced LLB incorp...

Basic Local Alignment Search Tool (BLAST) is a heavily used bioinformatics application that has gotten significant attention from the high performance computing community. The authors have taken BLAST execution a step further and enabled it to execute on grid resources. Adapting BLAST to execute on the grid brings up concerns regarding grid resource heterogeneity, which inevitably cause difficu...

This paper described the design and implementation of G-BLAST – a Grid Service for one of the most widely used bioinformatics application Basic Local Alignment Search Tool (BLAST). G-BLAST uses the factory design pattern to provide application developers a common interface to incorporate multiple implementations of BLAST. The process of application selection, resource selection, scheduling, and...

Multiple Input Multiple Output (MIMO) systems have been extensively studied in context of wireless communication system, which promising the both increased capacity and link level reliability. In this paper we will present an analysis of the Vertical Bell Laboratories Layered Space-Time (V-BLAST) system at high signalto noise ratio (SNR) region using BPSK, QPSK and 16-QAM modulation technique b...

Blast-associated sensory and cognitive trauma sustained by military service members is an area of extensively studied research. Recent studies in our laboratory have revealed that low-level blast exposure increased expression of transient receptor potential vanilloid 1 (TRPV1) and endothelin-1 (ET-1), proteins well characterized for their role in mediating pain transmission, in the cornea. Dete...

The Trauzl test is widely used to measure the explosive power of a substance by determining volume increase produced detonation tested charge in cavity lead block with defined quality and size. In this study, high-speed 3D digital image correlation (3D-DIC) system were evaluate effect stemming on blast hole. blasting experiments conducted emulsion explosives. materials adopted study sand, aggre...

the purpose of this study was to assess exposure to hand-arm vibration in tiller users, forty users of tiller in northeastern provinces of iran were examined to measure hand-arm vibration parameters such as root mean square acceleration (rms), total equivalent acceleration, vibration dose value (vdv) and crest factor in three directions (x, y, and z) and various operating modes for comparing th...

Underground gas storage are often subject to external dynamic loads, blast vibrations, and seismic disturbances, since they function as backup areas for the strategic national energy reserve, supply demand dispatch, storage. Currently, research on response characteristics, stability, disturbance control of underground storages under loads is still incomplete great practical importance ensure se...

High-pressure blast waves can cause extensive CNS injury in human beings. However, in combat settings, such as Iraq and Afghanistan, lower level exposures associated with mild traumatic brain injury (mTBI) or subclinical exposure have been much more common. Yet controversy exists concerning what traits can be attributed to low-level blast, in large part due to the difficulty of distinguishing b...

Exposure to a blast wave generated during an explosion may result in brain damage and related neurological impairments. Several mechanisms by which the primary blast wave can damage the brain have been proposed, including: (1) a direct effect of the shock wave on the brain causing tissue damage by skull flexure and propagation of stress and shear forces; and (2) an indirect transfer of kinetic ...
