  • Modified limiting dilution analysis : a mathematical model with biological interpretation

    Creator:
    Maier, Stefan H.
    Abstract:
    A mathematical model of Limiting Dilution Analysis for two limiting parameters is presented and investigated. Limiting Dilution Analysis is a microbiological cell assay developed for immunological application. In the given case we deal with the interaction between B lymphocytes, macrophage derived factor and T-independent antigens. The state of the art...

  • A dynamic model of exchange rate in relation to international trading

    Creator:
    Sun, Keong-wah Gary
    Abstract:
    It is popular belief that the volatility of the exchange rate is due to the balance of payments, which in turn is mainly influenced by the balance of trade. A closed-loop dynamic economic model is proposed to describe and analyse the effect of the international trade of a country on...

  • Instrumentation system for high speed data sampling of electrical machinery

    Creator:
    Brisbine, Glen Edward
    Abstract:
    The objective of this thesis is to develop criteria for a data acquisition system for electrical machinery capable of sampling a signal every 0.2 msec with a desired accuracy of 0.1%. The system to be measured includes both AC and DC voltage and current signals from several points. The main...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...

  • 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...

  • Passive source tracking from spatially correlated angle-of-arrival data

    Creator:
    Haisch, Hansjoerg
    Abstract:
    This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...

  • Design and simulation of a model for lymphocyte flow through single lymphnodes

    Creator:
    Heilig, Thomas
    Abstract:
    A compartmental model of lymphocyte circulation through a lymphnode is derived and simulated. The purpose of the model is to analyze experimental data and in turn design experimental plans from the analysis in order to obtain sufficient data for the organ-distributed immune response. The model will be used to predict...

  • Stabilizing control strategies for the doubly-excited machine

    Creator:
    Permantier, Gerald A.
    Abstract:
    Mathematical models for the doubly-fed machine are presented. The properties of the machine with rotor excitation as supplied by a power converter with voltage source character are reviewed. The peculiar torque-speed characteristic of the machine in this operating mode and its effect on the stability of the machine are presented....

  • Adaptive model-based motion estimation

    Creator:
    Crinon, Regis
    Abstract:
    A general discrete-time, adaptive, multidimensional framework is introduced for estimating the motion of one or several object features from their successive non-linear projections on an image plane. The motion model consists of a set of linear difference equations with parameters estimated recursively from a non-linear observation equation. The model dimensionality...
