FD-TD analysis takes a lot of advantages in dealing with the scattering from complex structures. In this paper, the approach of analyzing the scattering by infinite periodic structures is introduced. A new modified perfectly matched layer absorbing boundary condition is used to facilitate the FD-TD modeling. The successful design of infrared/millimeter wave frequency selective surface shows the va... View full abstract»

The conversion theory of vector wave function is one of important problems in electromagnetic. This paper presents a systematic treatment of the conversion technique and some applications. In this paper, the conversion relations of standard and non-standard spherical vector wave functions, standard and non-standard cylindrical vector wave functions, and spherical and cylindrical vector wave functi...

An information fusion method based on the combination of artificial neural networks (ANN) and Dempster-Shafer's evidence theory to identify point targets is introduced in this paper. Two kinds of targets fly together in high space from far away, so that each of them occupies only one pixel in the image obtained by the detector and has not any shape characteristics. These two targets are supposed t... View full abstract»

This paper takes the synthesizing evaluation about industrial economic benefits by examples and proposes a new method named maximizing deviation method for multiindices decision. The new method can automatically determine the weight coefficients among the multiindices and also can obtain the exact and reliable evaluation results without subjectivity. View full abstract»

In this paper, forecasting analysis to Box-Cox transformation models with a practical example is considered. Based on chosen generalized functional form, variables influencing passenger are selected by statistic mechanism, not just by subjective judgment or dependent on certain specified model, and forecasting models are constructed. Comparing with typical linear regression forecasting models, non... View full abstract»

In this paper, the structure characteristics of open complex giant systems are concretely analysed in depth, thus the view and its significance to support the meta-synthesis engineering with manifold knowledge models are clarified. Furthermore, the knowledge-based multifaceted modeling methodology for open complex giant systems is emphatically studied. The major points are as follows: (l) nonlinea... View full abstract»

This paper deals with identification of subset autoregressive time series model. A simulated annealing based on approach for determining the optimal subset of regression terms included in the subset autogressive model is introduced. Numerical examples are given to show the effectiveness of the proposed algorithm. View full abstract»

This paper takes the Sobel operator as example to study parallel sequential algorithm onto a memory-sharing multiprocessor by using a virtual machine. Several different parallel algorithms using function decomposition and/or data decomposition methods are compared and their performances are analyzed in terms of processor utilization, data traffic, shared memory access, and synchronization overhead...

To work efficiently with DSS, most users need assistance in representation conversion, i.e., translating the specific outcome from the DSS into the universal language of visual. In generally, it is much easier to understand the results from the DSS if they are translated into charts, maps, and other scientific displays, because visualization exploits human natural ability to recognize and understa...

In this paper, we present the double Beta spline curved surface which is controlled by double parameters including the algorithm principles, the treatment of boundary conditions, the alternation of projection, the algorithms of elimination hiddle line, the process to display and the primiples to produce the shaded curved surface. Based on all the above, a freedom surface modeling system (FSMS) is ... View full abstract»

Under the condition of normal strength and stress with unknown distribution parameters but getting a completed sample respectively, a comparison among the errors of some kinds of approximate limits for structural reliability has been made in this paper, basing on the exact limits presented. All results in this paper can be used with condition logical-normal distribution conveniently. View full abstract»
