The High Performance Storage System (HPSS) is a mature Hierarchical Storage Management (HSM) system that was developed around a network-centered architecture, with client access to storage provided through third-party controls. Because of this design, HPSS is able to leverage today's Storage Area Network (SAN) infrastructures to provide cost effective, large-scale storage systems and high perfo...

Explosion metal welding is high-speed angle oblique collision of two or more metal plates caused by detonation. The metal is joined – welded under high dynamic pressure creating by plastic deformation the waves on the bond interface, accompanied by local adiabatic heating 1 . The explosive metal cladding process can be divided into three stages: a) generation of explosion energy through the det...

a novel mathematical model has been developed to aid the formulation of emulsion explosives. this mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a ms excel program. the effects of the different content of nh4no3, nano3, h2o, and span-80 and composite fuel oil...

Phonolitic eruptions can erupt either effusively or explosively, and in some cases develop highly energetic events such as caldera-forming eruptions. However, the mechanisms that control the eruptive behaviour of such compositions are not well understood. By combining pre-eruptive data of well studied phonolitic eruptions we show that the explosive-effusive style of the phonolitic magma is cont...

In this paper a unified approach of lower bound functional area and cycle budget estimations is presented to predict area–delay characteristics of designs at system level. The estimations are mainly based on relaxing precedence constraints in a behavioral design description and are the most accurate estimations reported to date.
