With the development of e-business, interactions between enterprise and customer have gone into a new phase which network technology is the core competitiveness. Network customer reviews as an important part of network reputation influent consumers ' purchasing decisions, and bring enterprise digital feedback. This paper studied the theoretical framework which based on products feature mining issues...
In this paper, we describe how ontology techniques can be used to define rules for model transformation. Using ontology will enable us to model not only the meta-concepts but also the semantic context which can be used in model inference, and the transformation rules between models can be described by ontology defined in both models. The example presented in this paper is a transformation from an...
The EMP conductive susceptibility of a measurement and control device used in automatic management system is studied by experimental test. Two EMP waveforms with different rise time are applied to the devices. Responses of the EUT are measured and compared. The sensitivity thresholds of EUT are analyzed by statistical method. Results show the EMP with fast leading edge tends to cause more serious...
This paper presents an encoding scheme for pair sharing. Pair sharing relations and abstract operations required for a pair sharing analysis are encoded as Boolean functions and operations on Boolean functions. Preliminary experimental results with a prototype implementation are presented.
We present Tdpi, a typed process calculus for dynamic Web data. Tdpi features Web data in networks, hyperlinks, service calls, scripts, dynamically accessing data and typing. In Tdpi, a typing system disciplines data handing at the level of channels and processes. We proved subject reduction theorem which says that well-type will be preserved by reduction in the typing system.
A fast algorithm is proposed to restore the color images, degraded in a deterministic way by motion- blurred,by multichannel combination processing. Based on the color space conversion model, the point spread functions of the image motion on each plane of YUV422 image can be achieved.The U, V plane of YUV422 images are combined to form a newel plane which has the same size as Y plane. Then, the Y,...
According to the disadvantage of D-S theory and the limitation of improved combination rule, a modified combination rule based on rough set is presented. The weight of each evidence is obtained according to its influence degree on D-S combination result. Weighted averaging the evidence in the system, the Dempster combination rule is used to realize information fusion. The numerical example shows that...
Functionally graded piezothermoelastic material (FGPM) is a new piezothermoelastic material. Research work on its mechanical behavior has still been inadequate so far, which leaves room for a further discussion on the three-dimensional piezothermoelastic coupled analysis of FGPM annular plates. Suppose that all the electric, thermal and mechanical material properties have the same exponential distribution,...
This paper uses the FDTD method to investigate the magnetized plasma antenna erected on the metal ground. The influence of the external magnetic field B0 on the radiation properties of the antenna is presented. Numerical results demonstrate that the near-field distribution is strengthened and the far-field radiation shifts more to the upper half-space when the external magnetic field B0 builds up...
