  • Power deposition patterns of interstitial microwave hyperthermia applicators having tapered dielectric sheaths

    Publication Year: 1998, Page(s):103 - 105

    A coaxial dipole inserted into a cylindrical dielectric sheath is widely used as an interstitial microwave hyperthermia applicator. A means is described here of controlling the current distribution along the dipole and consequently controlling the distribution of the radiated power density by tapering the outside diameter of the dielectric sheath. Numerical results have been obtained for nylon cat... View full abstract»

  • Comparative study of multi-mass models of electrical drives with asynchronous motors

    Publication Year: 1998, Page(s):107 - 112

    The complexity of an electrical drive is such that its global study represents a difficult task at the design level as well as at the application level. To lighten this task, it is common practice to perform some simplifications; linearization of some characteristics, lumping of the distributed inertia of mobile parts with that of the motor rotor, etc. Because of the finite stiffness in the links ...

  • The characteristics and operating regions of distance relays in Z-plane

    Publication Year: 1998, Page(s):113 - 117

    This paper studies a new and general method to determine the characteristics and operating regions of distance relays for transmission lines in the complex plane (Z-plane). This method is easy to apply and seems not to be found in the literature. In [1] we presented several particular applications for electromechanical and static distance relays. Two general and important applications using the ne... View full abstract»

  • Comparisons between mesh and hierarchical ring networks for shared-memory multiprocessors

    Publication Year: 1998, Page(s):119 - 125
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3521 KB)

    Communication performance comparisons, in terms of message latency, between mesh and hierarchical ring interconnection networks for shared-memory multiprocessors are developed. Traffic in the networks is assumed to consist of the short, fixed-length messages needed for remote-memory read/write operations and cache coherency control. Square-mesh networks with bidirectional links and no end-around c... View full abstract»

  • A new approach for computing higher-order moments on linear systolic arrays

    Publication Year: 1998, Page(s):127 - 131
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1555 KB)

    The last few years have witnessed significant advances in the use of higher-order moments in various signal processing applications. As a result, the demand for efficient architectural designs for these functions is on the rise. In this paper we present a new formulation for implementing third- and fourth-order moments on linear systolic arrays. In the proposed approach the moments are computed as... View full abstract»

  • α-CORDIC: An adaptive CORDIC algorithm

    Publication Year: 1998, Page(s):133 - 138
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (10996 KB)

    In this work we briefly review the basic CORDIC algorithm and its drawbacks. Next, we propose an adaptive CORDIC algorithm (α-CORDIC) which removes all the CORDIC drawbacks: (a) the number of iterations is reduced, (b) full machine accuracy is assured, (c) the scale-factor problem is eliminated, (d) the operating range is unlimited, (e) computation noise is reduced, and (f) ability to utili...
