  • Application of multi-grid method to the computation of electromagnetic scattering problems

    Publication Year: 1997, Page(s):1 - 6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (736 KB)

    The multi-grid method has been known as an efficient iterative method for the linear systems and nonlinear systems that arise from finite difference approximations for partial differential equations. In this paper, the multi-grid method is extended to the application of solving integral equations which appear in electromagnetic scattering problems. The diakoptic theory is used for this purpose.

  • A new method of aperture analysis based on Gaussian beam expansion

    Publication Year: 1997, Page(s):7 - 18
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1169 KB)

    Gaussian beam expansion based on the aperture field distribution is studied systematically in this paper. The beam series representation for a radiated field and its asymptotic form are derived and applied to aperture analysis. Numerical results indicate that this method is able to analyze the radiated field accurately in all zones. View full abstract»

  • Motion estimation based on global and local compensability analysis

    Publication Year: 1997, Page(s):19 - 23
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (552 KB)

    This paper reports our study of a novel motion estimation algorithm based on global and local compensability analysis. The spatial correlation of motion field is used to reduce the burden of estimation computation and extra bit rate for motion vectors. Experimental results show that this algorithm is more efficient than the conventional methods, especially for temporal activity regions. View full abstract»

  • A numerical scheme to obtain the RCS of serrated targets using CG-FFT

    Publication Year: 1997, Page(s):24 - 32
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (859 KB)

    A numerical scheme to obtain the radar cross section (RCS) of scattering bodies of resonant size with serrated structure is described. The RCS is obtained by solving the electric field integral equation (EFIE) using the conjugate gradient-fast Fourier transform method (CG-FFT). With this combination, the computational time required to solve scattering problems of resonant size bodies is much less ... View full abstract»

  • Understanding the nature of predatory pricing in large-scale market economy with genetic algorithms

    Publication Year: 1997, Page(s):33 - 44
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (5605 KB)

    In this paper the nature of predatory pricing is analyzed with genetic algorithms. It is found that, even under the same payoff structure, the results of the co-evolution of weak monopolists and entrants are sensitive to the representation of the decision-making process. Two representations are studied in this paper. One is the action-based representation and the other the strategy-based represent... View full abstract»

  • An approach for integrating quantitative decision model with qualitative judgment

    Publication Year: 1997, Page(s):45 - 52
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (866 KB)

    In this paper, decision making in complex environment is considered and an approach integrating quantitative decision model with qualitative judgment is proposed. The concept of belief degree for quantitative decision model in a complex environment is presented. The integration in formulation and reasoning of quantitative model with qualitative judgment is studied. The combination of various belie... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (668 KB)

    Feedback mechanism is a specific feature of control systems, however, the similarity has been found in decision support systems. Just because of this, the DSS can provide a flexible learning and thinking environment, and help decision maker to solve semi-structured and unstructured problems actively and creatively. In this paper, the role and type of the feedback in decision making are discussed f... View full abstract»

  • Fuzzy interval value logic and fuzzy distributed value logic

    Publication Year: 1997, Page(s):60 - 65
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (730 KB)

    In this paper, two kinds of fuzzy logic named “fuzzy interval-value logic” and “uzzy distributed-value logic” with truth values in fuzzy intervals and probabilistic distribution functions are presented, respectively, and the syllogism (modus ponens) is given for each logic. It has been pointed out that they will have various applications in knowledge-based systems and o... View full abstract»

  • An investigation of formal techniques of protocol based on CFSM

    Publication Year: 1997, Page(s):66 - 72
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (839 KB)

    This paper investigates formal techniques of protocol based on communicating finite state machines (CFSM). Taking the protocols POLL-END (PE) and ACK-NACK (AN) as the examples, the paper discusses the formal description, validation and conversion of protocol with the CFSM, presents a protocol validation method and a protocol conversion algorithm based on the CFSM and demonstrates the applicability...
