    Due to their approximation capabilities and inherent adaptivity features, neural networks have been employed in modelling of complex nonlinear systems. This paper presents an approach to effectively identify a synchronous generator when only the inputs and outputs are accessible for measurement. Such an identifier (or model) can be used in an indirect adaptive control or internal model control sch... View full abstract»

    This paper proposes a method in which sensor fusion techniques coupled with image warping algorithms are used to interpret the signals from two infrared (IR) sensors to relate measures of distance and orientation relative to an obstacle. Development of the algorithm involves modelling of the sensor responses using a set of polynomials. The models are used to develop a `contour' model which yields ... View full abstract»

    The hierarchical routing model was proposed for ATM networks to reduce the amount of storage as well as communication overheads that would result if flat routing is used. This is achieved by having each node store and transmit only a partial set of information about the network status instead of a complete one. However this may result in a degradation of the performance of these networks due to th... View full abstract»

  • Frequency dependent network equivalent algorithm for AC power systems

    Publication Year: 1996, Page(s):639 - 642 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (256 KB)

    In electromagnetic transients studies, only a small part of an AC power system can be modeled in detail. The remaining parts of the system should be reduced to equivalent networks. Different methods have been developed to generate frequency dependent network equivalent (FDNE) models. These FDNE models consist of simple R,L and C branches that reproduce the impedance frequency characteristic of the... View full abstract»

  • A new adaptive FEC scheme for ATM communications

    Publication Year: 1996, Page(s):806 - 809 vol.2
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB)

    Congestion in ATM communications is a significant issue as it can have a dramatic effect on critical or real-time data. Forward error correction (FEC) can be used to decrease or eliminate this effect. Conventional FEC has a uniform error correction capability, which can result in poor bandwidth utilization. Adaptive FEC is more suitable because it allows a different quality of service for each dat... View full abstract»

  • Image compression with singularity preservation

    Publication Year: 1996, Page(s):894 - 898 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (640 KB)

    This paper presents a new approach to lossy image compression through singularity preservation to obtain high compression ratios. The concept of this approach is based on a conjecture that image singularities carry most of the perceptual information, hence the essential part of an image should be represented by its singularity as opposed to its energy alone. Wavelet maxima have been chosen to repr... View full abstract»

  • An effective approach for optimal design of fuzzy controllers

    Publication Year: 1996, Page(s):542 - 545 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (364 KB)

    The novel approach described in this paper represents a substantial departure from the complexity and consequent difficulties involved in the optimal design of fuzzy controllers. By reducing the number of design parameters of a fuzzy controller, the search in a hyperspace of 94 dimensions will collapse into a search in a space of 7 dimensions. In this way, a significant enhancement can be achieved... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    Obstacles within a robot's work space impose constraints on the motion of the robot. These motion constraints have to be taken into account during the collision-free path planning process. We investigate the problem of representing these motion constraints in the robot's work space. In general, these motion constraints could be placed on any part of the robot. We present a novel approach to transf... View full abstract»
