    In order to develop a basic understanding of the interaction of an ultra-wideband electromagnetic pulse with a conducting body of revolution (BOR), one must accurately compute the resulting induced currents. The general problem considered here is the computation of the induced currents on a conducting BOR which contains an aperture on one end and an electrically thin circumferential slot of variab...

    One of the topics in an undergraduate electrical engineering curriculum in a electromagnetics or power systems course is the transmission line. When the line is modeled with the distributed parameters, the power P, delivered to the load at the end of a lossless line is usually of interest and is given by: P=1/2|V+|/R0(1-|KL|2) where V+ is the ...

  • A statistical model for path delay faults in VLSI circuits

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (368 KB)

    Faults in digital circuits are primarily the results of various random defects which can occur during manufacturing. These random defects can introduce DC (stuck-at) faults as well as AC (delay) faults. Previous work on statistical modeling and analysis for delay fault testing assumes that at most a single delay fault can occur along any given path in the circuit under test. In this paper, we stud... View full abstract»

    The electronics industry has adopted hardware description languages (HDLs) as a method to manage complex application specific integrated circuit (ASIC) designs. However, ambiguous code and inappropriate usage of HDL syntax may restrict an IC design engineer's ability to fully exploit the advantages offered by HDLs and logic synthesis tools.

    The popularity and usefulness of microstrip antennas has made it increasingly necessary to find a method to accurately determine the radiation patterns of these antennas through the modeling process. One such tool studied was MSC/EMAS and MSC/XL, which are programs that utilize the finite element method. In this paper, these programs are used to construct and analyze several microstrip antennas su... View full abstract»

    A new Monte Carlo method is introduced. The fixed-radius floating random walk combines the strong points of the two classical Monte Carlo methods, namely the fixed random walk and the floating random walk. The method is used to solve Poisson's equation. Two typical problems in rectangular and axisymmetrical solution regions are used to illustrate the method's lower computation time and higher degr...

    Effective rate variation during active speech is a necessary component of sophisticated variable rate speech compression schemes. Here, we use open-loop estimates of spectral shape to roughly determine signal bandwidth and bit allocations for variable rate encoding of spectral parameters. We analyze the application of the relative entropy functional to sets of line-spectrum pairs (LSPs) and transf... View full abstract»

    Local area network (LAN) switches are increasingly being used to subdivide large LAN segments into multiple connected LAN “microsegments”. A LAN switch is similar to a LAN bridge, but is typically higher in performance and has more ports. Communication between stations on different segments is through the LAN switch. A performance analysis is presented for a token ring LAN switch for t... View full abstract»

    The currently existing models of computation, control-flow and data-flow, have their limitations and weaknesses in utilizing parallelism adequately. A new refined model of computation, called associative dataflow, has been previously proposed in the literature which attempts to circumvent the bottlenecks inherent in conventional dataflow using associative memories. In this new model of computation... View full abstract»

    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»
