  • An introduction to system full-decomposition theory

    Publication Year: 1991, Page(s):15 - 26
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1047 KB)

    In this paper, the system full-decomposition theory is introduced and its mathematical properties, as an algebraic system, are provided. A partition trinity of the algebra on a machine gives efficiently the information dependence between inputs, states and outputs within a triple of partitions, and they serve as a powerful tool to the full-decompositions of machines. In information processing syst... View full abstract»

  • A new method of structuring the hierarchy of a system

    Publication Year: 1991, Page(s):27 - 33
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (681 KB)

    Structuring the hierarchy of a system is an important link of solving problems with the analytic hierarchy process. This paper gives and proves the two theorems about the relationship between the hierarchy and the reachability matrix of the system. On the basis of it, we propose a method of structuring hierarchy by directly using the reachability matrix of the system. This method is simpler and cl... View full abstract»

  • A model-based, aspiration-led decision support system NY-IEDSS

    Publication Year: 1991, Page(s):34 - 43
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1297 KB)

    An Al-aided simulation system embedded in a model-based, aspiration-led decision support system NY-IEDSS is reported. The NY-IEDSS is designed for mid-term development strategic study of the Nanyang Region in Henan, China. and is getting beyond its prototype stage under the decision maker's (the end user) orientation. The integration of simulation model system, decision analysis and expert system ... View full abstract»

  • A GMRP approach for reliability analysis of repairable systems

    Publication Year: 1991, Page(s):44 - 54
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1059 KB)

    We propose here a mathematical approach for the study of repairable systems with arbitrary distributions. The idea is to define a new type of stochastic process, called a generalized Markov renewal process (GMRP), which may describe the transition behavior of the stochastic process at non-regenerative points. In the paper an analytical method for the GMRP is put forward and the formulas are then p... View full abstract»

  • The development and application of combined thermoregulatory mathematical models

    Publication Year: 1991, Page(s):55 - 64
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1313 KB)

    Thermoregulatory mathematical models have being developed for more than half a century and obtained more and more wide application. Among them, the “engineering-physiological” thermal models, which correlated closely to the man-machine-environment system, are the ones that developed most rapidly and have been widely accepted by thermal physiologists and environmental control engineer...

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2134 KB)

    A Bezier interpolation approach is proposed which uses local generation of endpoint slopes and forces the curve and the surface to pass through an arbitrarily specified point to control and modify the shape of curve and surface, making the result satisfactory. View full abstract»

  • Input admittance and current distribution of infinitely long circular cylindrical antenna driven at center

    Publication Year: 1991, Page(s):73 - 81
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (739 KB)

    In this paper, by change of integration path in complex spectrum domain and by defining input admittance as the ratio of complex radiated power to amplitude of square of voltage across the gap, new expressions of admittance (valid for all frequencies) of infinitely long cylindrical antenna with and without conducting ground are obtained. Meanwhile corresponding formulas of current distribution are... View full abstract»

  • Investigation on suspended stripline and end-coupled bandpass filter

    Publication Year: 1991, Page(s):82 - 90
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (810 KB)

    In this paper, the variational method combined with Green's function is used to analyze the characteristics of suspended stripline. The result is in good agreement with references. The design of mm-wave end-coupled bandpass filter with suspended substrate is discussed. The computer programs for design of suspended stripline and bandpass filter are established.

  • Radar imaging based on iterative algorithms

    Publication Year: 1991, Page(s):91 - 99
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1145 KB)

    It has long been realized that the problem of radar imaging is a special case of image reconstruction in which the data are incomplete and noisy. In other fields, iterative reconstruction algorithms have been used successfully to improve the image quality. This paper studies the application of iterative algorithms in radar imaging. A discrete model is first derived, and the iterative algorithms ar... View full abstract»

  • Radar cross section calculation for wing-body blended targets

    Publication Year: 1991, Page(s):100 - 108
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (796 KB)

    A new methed of calculating the radar cross section (RCS) for wing-body blended targets is presented and verified. The method utilizes a computer program for modeling targets' geometry in terms of small pieces. The calculation is based on physical optics approximation. Examples are given to show the validity of the method. View full abstract»

  • A high speed detection scheme for point targets in a multitarget environment

    Publication Year: 1991, Page(s):109 - 123
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1554 KB)

    The purpose of this paper is to develop a high speed detection scheme for moving and / or stationary point targets in a multitarget environment as registered in an IR image sequence. An iterative approximate 3-D line searching algorithm based upon the geometric representation of lines (for non-maneuvering targets in space) in a 3-D space is derived. The convergency of the algorithm is proved. An a... View full abstract»

    Due to the good performance of tracking low elevation target as compared to microwave and the superiority in penetrating smoke, dust, fog, and dry snow as compared to infrared, a Ku and Ka dual band experimental radar was designed and developed. This Ku and Ka dual band experimental radar is an amplitute-comparison monopulse tracking and guiding radar. The constitution and parameters of this radar... View full abstract»
