  • Critical evaluation of Ouyang's model reduction method

    Creator:
    Jia, Zuxin
    Abstract:
    A model reduction method for stable, linear, time-invariant, continuous systems is critically studied. This method, proposed by Prof. Ouyang, is based on the concept of power dispersion and the least-squared estimation technique. The reduced models obtained by this method retain the stability of the stable, high order original systems and...

  • Pipelined multiprocessor computer architecture and fast parallel algorithms for real-time robot control

    Creator:
    Mun, Wangjin
    Abstract:
    As a result of the automation revolution, robots are assuming ever more complex and demanding tasks. Robot system control schemes for fast and precise robot motion require utilization of the entirety of the robot dynamic formulations and the ability to evaluate these formulations in real-time. The dynamic formulations, which take...

  • A study of the temperature dependence of the DC current-voltage characteristics of AlGaAs/GaAs heterojunction bipolar transistors with application to bandgap voltage reference sources

    Creator:
    Gazeley, William G.
    Abstract:
    The bandgap voltage reference technique, as implemented in Silicon technology, has evolved to a state of advanced development and become the method of choice for temperature independent voltage biasing in integrated circuits. The heterojunction bipolar transistor (HBT), fabricated from epitaxial A1GaAs /GaAs, is developing to a point where basic circuit...

  • Sliding mode controller for robot manipulator

    Creator:
    Kang, Seong K.
    Abstract:
    The sliding mode controller, based on the theory of the Variable Structure System (VSS), is considered for a robot manipulator. By consideration of VSS theory, the nonlinear interactions of manipulator dynamics are suppressed by use of linear sliding equations, and VSS robustness with respect to the unknown physical manipulator parameter...

  • Static task scheduling and grain packing in parallel processing systems

    Creator:
    Kruatrachue, Boontee
    Abstract:
    We extend previous results for optimally scheduling concurrent program modules, called tasks, on a fixed, finite number of parallel processors in two fundamental ways: (1) we introduce a new heuristic which considers the time delay imposed by message transmission among concurrently running tasks; and (2) we introduce a second heuristic...

  • Quasi-TEM and full wave numerical methods for the characterization on microstrip discontinuities

    Creator:
    Hill, Achim
    Abstract:
    Static and dynamic numerical techniques which are suited for the analysis and simulation of various planar microstrip components encountered in hybrid and monolithic microwave integrated circuits are presented. The static analysis makes use of an excess source formulation in conjunction with an efficient mathematical treatment to extract the discontinuity parameter...

  • Distributed architecture and fast parallel algorithms in real-time robot control

    Creator:
    Binder, Eli Eliyahu
    Abstract:
    Control algorithms for accurate and fast moving robots require the use of the complete dynamic model of the robot. The complete dynamic model takes into account the nonlinearity and coupling terms of the whole structure. The time of computing the dynamic equations determines whether they are usable in practical applications....

  • Modeling and characterization of hemt devices

    Creator:
    Chang, Chujyh
    Abstract:
    Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of...

    Abstract:
    This thesis reports on the crystal growth, fabrication, modeling and performance of Graded Index-Separate Confinement Heterostructure laser diodes which contain pseudomorphic InGaAs as the active region material. Laser epitaxial layers were grown with different indium mole-fractions, and a constant InGaAs layer thickness of 10 nm, on both sides of the...

  • Electrical characterization of silicon and silicon dioxide materials

    Creator:
    Sze, Wing-Il
    Abstract:
    The major goal of this research work was to develop better electrical measurements for the evaluation of silicon material quality. The first approach investigated was the Zerbst generation lifetime measurement technique. It was demonstrated that the error in the estimation of the generation lifetime obtained with this technique could be...
