  • A simulation study of a heuristic technique for approximating availability percentiles for cascaded independent systems

    Creator:
    Squire, David Charles
    Abstract:
    This thesis presents work done to verify the accuracy of a heuristic method for computing availability percentiles for cascaded independent systems. Previous work has provided a model for a single line that will be used as the basis for a simulation of cascaded and parallel systems of lines. The simulation...

  • Analysis and modeling of planar microstrip spiral inductors on lossy substrates

    Creator:
    Lutz, Richard D.
    Abstract:
    The advent of low-cost RFIC's fabricated in Silicon-based technologies has led to the use of monolithic lumped elements which are located on-die. While it is clearly advantageous to have a high degree of integration and thus fewer off chip elements, parasitic losses due to semiconducting substrate effects can be a...

  • Modeling and characterization of multiple coupled lines

    Creator:
    Tripathi, Alok
    Abstract:
    A configuration-oriented circuit model for multiple coupled lines in an inhomogeneous medium is developed and presented in this thesis. This circuit model consists of a network of uncoupled transmission lines and is readily modeled with simulation tools like LIBRA© and SPICE©. It provides an equivalent circuit representation which is simple...

  • Field theoretic analysis of a class of planar microwave and opto-electronic structures

    Creator:
    Hahm, Yeon-Chang
    Abstract:
    With increasing operating frequencies in CMOS RF/microwave integrated circuits, the performance of on-chip interconnects is becoming significantly affected by the lossy substrate. It is the purpose of the first part of this thesis to develop a rigorous field theoretic analysis approach for efficient characterization of single and multiple coupled interconnects...

  • Model development via delay extraction for the time-domain simulation of lossy transmission lines.

    Creator:
    Blevins, Chris
    Abstract:
    This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....

  • Time domain simulation of multiconductor lossy transmission lines by the method of characteristics

    Creator:
    Orhanovic, Neven
    Abstract:
    A numerical technique to compute the time domain response of multiconductor lossy uniform and nonuniform lines terminated in general nonlinear elements is presented. The technique is based on the generalized method of characteristics. The method transforms the original system of transmission line equations into a system of ordinary differential equations....

  • Monitoring and diagnosis of a multi-stage manufacturing process using Bayesian networks

    Creator:
    Wolbrecht, Eric T.
    Abstract:
    This thesis describes the application of Bayesian networks for monitoring and diagnosis of a multi-stage manufacturing process, specifically a high speed production part at Hewlett Packard. Bayesian network "part models" were designed to represent individual parts in-process. These were combined to form a "process model", which is a Bayesian network...

  • Efficient heuristics for buffer allocation in closed serial production lines

    Creator:
    Vergara Arteaga, Hector A.
    Abstract:
    The optimal allocation of buffers in serial production systems is one of the oldest and most researched problems in Industrial Engineering. In general, there are three main approaches to the buffer allocation problem when the objective is to maximize throughput. The first is basically a systematic trial and error procedure...

  • Analysis of planar multi-conductor multilayered structures by network analog method

    Creator:
    McVeety, Joseph J.
    Abstract:
    In this thesis the network analog method is used to analyze various planar multi-conductor structures in multilayered, lossy dielectric media. The method is based on an efficient impedance network representation of the finite difference approximation of Laplace's equation for the electric potential. Using the network analog method, the transmission line...
