  • A second-order statistics based algorithm for blind separation of signals

    Publication Year: 1999, Page(s):1 - 6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (939 KB)

    We propose an information theory based objective function for measuring the statistics independent of source signals. Then, we develop a learning algorithm for blind separation of nonstationary signals by minimizing the objective function, in which the property of nonstationary and direct architecture neural network is applied. The analysis demonstrates the equivalence of two neural architectures ... View full abstract»

    In this paper, we discuss the advantages of intergrated services digital network (ISDN) as an infrastructure for telemedicine applications. The facilities provided by ISDN, which are necessary to telemedicine, are listed and some of the ISDN solutions to telemedicine are discussed. Some of the current popular telemedicine systems that based on ISDN are mentioned, with some discussion of the future... View full abstract»

  • A java-based approach for developing Web application system

    Publication Year: 1999, Page(s):15 - 21
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (869 KB)

    This paper adopts server-side Java programming model: model-view-controller to construct web-based shopping system framework. Using servlets, Java server pages (JSPs) and JavaBean technologies, we provide a standard, open, robust and cross-platform architecture. It can guarantee system-independence. Presented framework provides a clean separation of presentation from business logic which meets use... View full abstract»

  • Neuro-optimal guidance control for lunar soft landing

    Publication Year: 1999, Page(s):22 - 31
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1122 KB)

    Returning to moon has become a top topic recently. Many studies have shown that soft landing is a challenging problem in lunar exploration. The lunar soft landing in this paper begins from a 100km circular lunar parking orbit. Once the landing area has been selected and it is time to deorbit for landing, a ΔV burn of 19.4m/ s is performed to establish a 100 × 15km elliptical or... View full abstract»

  • On the solutions of the matrix equations in optimal stochastic control

    Publication Year: 1999, Page(s):38 - 43
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (567 KB)

    In this paper, the matrix algebraic equations involved in the optimal control problem of time-invariant linear Itô stochastic systems, named Riccati — Itô equations in the paper, are investigated. The necessary and sufficient condition for the existence of positive definite solutions of the Riccati-Itô equations is obtained and an iterative solution to the Riccati-It&#x... View full abstract»

  • Discrete quasi-sliding mode tracking controller with time delay technique

    Publication Year: 1999, Page(s):44 - 49
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (621 KB)

    Robust discrete quasi-sliding mode tracking controller is developed with discrete reachinglaw for trajectory tracking in the presence of modeling uncertainty and unknown disturbance. The conventional prior knowledge of uncertainty upper bounds being replaced by an on-line estimation used in the controller to cancel the slowly varying uncertainties by the mechanism of time delay. This method reduce... View full abstract»

  • Coherent phase-coded pulse train with Doppler cascade-processing for detection of aircraft target in a HF radar

    Publication Year: 1999, Page(s):50 - 56
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (928 KB)

    The effect of range-Dapper coupling caused by aircraft moving at very high speed makes trouble on selection of waveform parameters by using frequency-modulated interrupted continuous wave (FNHCW) or frequency-coded pulse (FCP). It also limits the increasing of coherent intergration time. In this paper, application of coherent phase-coded pluse train (CPCPT) solves range-Doppler coupling well. Rele... View full abstract»

  • Multicomponent chirp signal detection using fractional fourier analysis

    Publication Year: 1999, Page(s):57 - 63
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (886 KB)

    The aim of this paper is to propose a novel technique for the detection of multicomponent chirp signal and the parameter estimation based on fractional Fourier transform (FRFT). The relationship between the FRFT and the Wigner-Ville distribution (WVD) is investigated and the performance of the new approach is analyzed both in the computation complexity and the resolution in the fractional Fourier ...

    This paper develops a new replacement policy for a system with multiple spare units. An optimal replacement period is determined by maximizing the mean time to failure of the system. We show that there exists a finite and unique optimal replacement period Tk for units with strictly increasing failure rates. We also proof that the optimal replacement period for a system with spares is de... View full abstract»
