Performance prediction for the high performance computer system is of great importance for designing, implementing, and optimizing system. As a widely used technique for predicting performance, simulation method attracts more and more attention from the research community. Based on analyzing the problems in the current performance simulation techniques, we present a key idea of the performance simulator...
During the expressed of the virtual battlefield situation, a lot of irregular objects have to be simulated. Particle system is an effect way for the modeling of fuzzy object, which need dynamic modeling. We expatiate on the application of the particle system from the aspect of tactics situation express and from two aspects: combat entity simulation and environment entity simulation, and analyzing...
In designing a large inclined angle hydraulic support, the structure characteristics of four-bar linkage is presented, and ADAMS software is applied to four-bar linkage modeling and simulation. In order to attain optimal results, parameterized modeling and optimization is achieved, and the design results meets the practical requirements very well. By means of this virtual design method, the errors...
As a macro complex systematic engineering, the Digital Ocean project is an ongoing task in china. The mission of the Digital Ocean is to build an interactive network information system based on a three-dimensional globe. The Digital Ocean can help provide integrated information on historical, current and future states of ocean and coastal zone. This paper addresses the architecture of Digital Ocean,...
