Suchman put the system reasonable into three parts: pragmaic, meral and cognitive. There are three parts of system usability model based on system reasonable theory such as business application system continuity, service system continuity and information communication system continuity.
Embedded systems are targeted for specific applications under constraints on relative timing of their actions. In this paper, we proposed a co-synthesis approach to hardware/software (HW/SW) co-design for embedded system based on Dynamic Data Flow (DDF). Firstly, we introduced the theory of DDF and presented a methodology of designing embedded system on system-level that depends on decomposing DDF...
This paper studies the soft tissue deformation of Virtual Surgery Simulation, and using OpenGL to establish the virtual soft tissue deformation system based on mass-spring model. Discussed with fidelity and real-time of the soft tissue deformation in Virtual Surgery Simulation. By Comparing quadrilateral topology, the regular hexagon topology based on mass-spring model is proposed, discussed the dynamic...
The notion of update pattern awareness in the context of continuous queries over relations, streams and sliding windows was introduced in previous researches. This investigation concerns the access costs of data structures for the intermediate results or final results of continuous query processing over sliding windows by update pattern awareness.The ladder structure was employed to store intermediate...

System building based on 3D modeling can greatly improve the efficiency for the trooppsilas daily training. According to the equipment training requirement, the system architecture and functions are put forward. The whole system includes six simulators such as network simulator, headquarters...
Now, network attack-defense is a hotspot of network security fields. Computer network war will be the most important type of future information war. A relative general and extensible simulation platform can offer training support for building the troopspsila battle effectiveness. So a method of building Network Attack-Defense Simulation Training Platform (NADSTP) based on HLA and network simulation...
Molecular dynamics simulations have become a significant computational approach to study complicated physical phenomena at the atomic level. Nevertheless, accurate simulations are limited in size and timescale by the available computing resources, which make the simulations very time-consuming. This consequentially leads to tremendous computational requirements. Therefore, the need for speeding up...
There are so many scene simulation application systems and they are built based on the different special 3D models data formats such as OpenFlight, 3DS, VRML, GLS, etc. These systems are developed almost in all fields. For example, urban programming, battlefield environment, traffic design ,virtual touring, simulation training, and so on. Actually, they are same at the development flow and key technologies...
The model of city E-service with grid based on new growth theory will have the long-time life time according to the theory of endogenous growth, learning-by-doing and Knowledge spillovers theory. Learning by doing theory makes the model more efficiency. Knowledge spillovers theory makes the entourage organization grow up together. The grid computing theory gives the city platform more power. The grid...
Soldiers possessing of network attack-defense ability are the key factor for future information war. Aiming at the problem of lacking daily training and drilling environment, a method of building network attack-defense simulation training system (NADSTS) based on HLA is put forward. With the method, attack and defense training are designed as different federation member. The system is divided to presentation,...
Scene simulation technology has been the basal component for building 3D simulation application now.

This a new access control model DRBAC based on role and department is proposed, which extends the traditional role-based access control (RBAC) model. The new model adds the abstraction of the department property and simplifies the operational process by means of the authenticating management based on transaction.
To achieve the shift quality evaluation effectively, reasonably and timely, a new model to evaluate shift quality based on evidence theory and fuzzy neural network (FNN) is proposed in the paper. A method combining subjective evaluation and objective evaluation is adopted. Subjective evaluation provided by various drivers is aggregated by means of evidence theory, which can improve the reliability...
