In order to integrate process operation system effectively, a multi-layer information integration framework is proposed. Firstly, the characteristics of process operation system are analyzed, and then the data and functions that need to be published are confirmed. Secondly the process operation system is wrapped into web service. Then enterprises can dynamically integrate all web services distributed...
The communion and sharing of knowledge is an important precondition to innovate. Innovation needs the flow and collision of knowledge. The flow is not aimless, but orderly through control. In order to manage distributed and ocean knowledge in an open and dynamic interconnection environment, resource space is used in knowledge modeling. Knowledge depicted through matrix is presented in resource space...
When a system is developed, Requirements Document is generated by requirement analysts and then translated to formal specifications by specifiers. If a formal specification can be generated automatically from Natural Language Requirements Document, system development cost and system fault from experts' misunderstanding will be decreased. Also, if we would like to get the higher accuracy in analysis...
In order to solve the larger local displacements problem of common suspended structure, a novel suspended structure: semi-rigid suspended structure is put forward, and the 3D model is built by using ANSYS software, the damping performance of the new structure is analyzed under two typical seismic waves. The results showed that the semi-rigid suspended structure could effectively reduce the displacement...
This Targeting to the complexity and large amount of 3D(three-dimensional) reconstruction of complex scene in virtual environment, Firstly, The 3D data acquisition and conversion principle, scene modeling and texture mapping method were described. Secondly, the geometric modeling and image fusion method was presented. Thirdly, the reconstruction mathematical model of image based on entropy variation...
As a type of artificial intelligence model derived from the human brain system, the neural network has the function to simulate the human brain. The paper is intended to introduce the neural network into the measurements and calculations of space object orbits, thereby giving fuller play to its advantages in dealing with the non-linear issues, and thus making it possible to design the prediction algorithm...
Virtual reality technique is applied in the industry widely, while the application of virtual assembly is rare in agricultural equipment. In this paper, we state several characteristics and key technologies on virtual assembly and have developed the virtual assembly system based on OSG which is a rendering engine. Finally, we described application of virtual assembly technique based on virtual reality...
Supplier lies in first node of SC (supply chain). Rational supplier evaluation and selection are important to the whole SC's agility and competition. Based on analysis of supplier management, Supplier evaluation guide line is discussed in paper. Then neural network-based supplier evaluation model is established. BP dynamic neural network is applied in constructing model and the amelioration weight...
