Grid architecture model of network centric warfare

1.INTRODUCTIONOGSA[1,2,4,5,7]integrates key grid technologies withWebservices mechanisms to create a distributed sys-temframework based around the grid service.OGSAdefines mechanisms for creating,managing,and ex-changing information among entities called grid ser-vices.Succinctly,a grid service is a Web service thatconforms to a set of conventions(interfaces and be-haviors)that define howa client interacts with a gridservice.As the embodi ment of the information warfare,NCW[2,3,6]is a…

The input work expression and the thermodynamics-based modelling framework for unsaturated expansive soils with double porosity

In this paper, based on the porous media theory, the specific expressions of the total stress and the input work of unsaturated expansive soils with double porosity are proposed, and then the energy-conjugate variables are further derived. We make distinctions between the effects of capillary water and adsorbed water on the soil behaviour, as well as between the deformations of microand macrostructure. According to the derived input work expression and the work-energy-dissipation relations for an open multiphase thermodynamic system, we establish a thermodynamics-based modelling framework for unsaturated expansive soils with double porosity.     

Nano-mechanical and tribological properties of copper matrix composites reinforced by graphene nanosheets

The impacts of graphene nanosheets content on microstructure, nano-mechanical and tribological properties of the copper matrix composites were investigated. The graphene nanosheets randomly distributed in copper matrix, which obviously hindered its grain growth. The elastic modulus and nano-hardness of the copper matrix composite with 0.2 wt% graphene nanosheets were enhanced 47.5% and 54.7% compared to these of pure copper, respectively. The average creep degree(5.1%) was lower than that(11.8%) of pure copper in holding stage. The creep rate(ca. 0.016 nm/s) decreased 10 times as that(ca. 0.16 nm/s) of pure copper in steady-state creep. The tribological performances were improved dramatically with increase of graphene nanosheets content.     

Global cooling controls on the chemical weathering as evidenced from the Plio-Pleistocene deposits of the North China Plain

Major element concentrations were analyzed on the sediments of a 203.6-m core from the North China Plain near Tianjin. The chemical index of alteration (CIA), Al2O3-(CaO+Na2O)-K2O diagram and elemental ratios, such as Al/K and Ti/Na, were used to reveal information of chemical weathering in the source regions since the late Pliocene. Results show that the fluvial materials in the North China Plain were derived from vast regions, which were in the early Na and Ca removal stage and underwent numerous upper-crustal recycling processes. Proxies of chemical weathering show a decreasing trend, in parallel with the global cooling since the late Pliocene, suggesting a strong role of the global cooing in controlling the continental chemical weathering intensity.
