    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (872 KB)

    As expert systems technology has matured and migrated into mainstream computing, there are still areas which are overlooked in education prospective knowledge engineers. This paper addresses this issue, and provides a message to educators that expert and knowledge-based systems should be an important strategic science and technology for many organizations.

  • On intelligent cooperative system

    Publication Year: 1995, Page(s):7 - 10
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (591 KB)

    The paper presents our research efforts motivated by the apparent need to combine conventional, preexisting computing functions with novel knowledge-based functions. This has been likened to what occurred in the evolution of primates, where the “new brain” (the cortex) was added to, layered upon, and given control over the “old brain” common to the less complex animals.

  • Performance of feedback BP networks

    Publication Year: 1995, Page(s):11 - 18
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1024 KB)

    Through adding feedbacks in multi-layer BP networks, the network performance is improved considerably compared with general BP network and Hopfield network, particularly the associative memorizing ability. In this paper, we analyze the two networks: feedback BP network and Hopfiled network and compare the property between them. The conclusion shows that feedback BP network has more powerful associ...

  • Implementing an artificial neural network computer

    Publication Year: 1995, Page(s):19 - 24
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (906 KB)

    Based on the implementation of NNSPC (Neural Network Synchronous Parallel Computer) developed by NJU, this paper discusses two schemes for implementing artificial neural network computer with distributed memories: One is Switch Network Structure; the other is Ring Topology Structure. This paper gives a comparison between the two schemes and the principles of scheme selection. View full abstract»

  • A parallel multicomputer simulation system

    Publication Year: 1995, Page(s):31 - 40
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1456 KB)

    In this paper, a homogenous parallel simulation system is presented in detail for continuous-system simulation. The system is constructed by a host computer and 11 transputers connected into a topology of “Super-Node” which is very suitable for simulation of stiff systems. An automatic software interface run in the host is developed to partition simulation model, either equations or ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1007 KB)

    Active message is an efficient and versatile communication architecture. The high performance of it is closely related to the choices made in implementing. This paper discusses the mechanism of active message and considerations should be taken in implementation. We propose improvements in method of message reception and buffer management. Programming model and method using active message are also ... View full abstract»

  • Seismic 3D prestack time migration on parallel computers

    Publication Year: 1995, Page(s):49 - 55
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1406 KB)

    Parallel versions of prestack Kirchhoff 3D integral migration algorithm, which is suitable for seismic data processing, are described in this paper. Firstly, the inherent parallel characteristics of seismic data processing are analyzed. Then some principles in algorithm partition are discussed. Based on these analyses and the system architecture, communication mechanism, this algorithm is divided ... View full abstract»

  • Implementing higher-order Gamma on a massively parallel computer — A case study

    Publication Year: 1995, Page(s):56 - 62
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (917 KB)

    Gamma is a kernel programming language with an elegant chemical reaction metaphor in which programs are described in terms of multiset rewriting. Gamma formalism allows one to describe an algorithm without introducing artificial sequentiality and leads to the derivation of a parallel solution to a given problem naturally. However, the difficulty of incorporating control strategies makes Gamma not ... View full abstract»

  • A nonprecedence-based query schedule algorithm on heterogeneous multiprocessor system

    Publication Year: 1995, Page(s):63 - 69
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1024 KB)

    There has been a number of algorithms designed to handle intra-query or inter-query scheduling in multiprocessor-based parallel database system. They all have the assumption that the processors are identical. But in some cases, such as shared nothing environment, this assumption would not be fully valid. In this paper we devise and evaluate a scheduling algorithm ELLIST to handle nonprecedence-bas... View full abstract»

  • SWHC-strict weak hybrid coherence model for Pthread

    Publication Year: 1995, Page(s):70 - 75
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (840 KB)

    DSM(SVM) is a memory model which was proposed at the 1980s'. DSM solved the problem that scalability was contradict with easy programming and merge their merits. The efficiency of DSM is still a problem. The proposed solutions include prefetching and adopting new coherence model, but neither of them is a perfect solution. Prefetch will be less efficient when there are too many false sharing. The w... View full abstract»

  • Algebraic stability of multistep Runge-Kutta methods

    Publication Year: 1995, Page(s):76 - 82
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (726 KB)

    A series of sufficient and necessary conditions for the algebraic stability of multistep Runge-Kutta methods is obtained, most of which can be regarded as extension of the relevant results available for Runge-Kutta methods, especially, for Radau I A, Radau II A and Gaussian Runge-Kutta methods.

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (885 KB)

    In 1992, Cooper [2] has presented some new stability concepts for Runge-Kutta methods which is based on two slightly different test problems, and obtained the algebraic conditions that guarantee new stability properties. In this paper, we extend these results to general linear methods and to more general problem class Kστ The concepts of (k, p, q)-secondary stability and(k... View full abstract»
