  • Optimization of stochastic dynamic system with random coefficients

    Creator:
    Yi, Man Hyung
    Abstract:
    The problem of optimization of stochastic dynamic systems with random coefficients is discussed. Systems with both Wiener processes and uncertain random-process disturbances are dealt with in this dissertation, and these include certain bilinear stochastic systems. It is the purpose of this thesis to study the optimal control and, to some...

  • Implementation of a digital PID controller in a hierarchical distributed control system

    Creator:
    Yu, Chi-ming
    Abstract:
    In this is paper, an implementation of a microprocessor based distributed control system (DCS) is investigated. This system consists of a digital PID controller and a high level operator interface. A temperature control system was designed to experimentally verify the system operation. Experimental results compare closely with theoretical prediction. The...

  • EDLAN, an educational local area network

    Creator:
    Yu, Hua
    Abstract:
    EDLAN is a simple, inexpensive local area network suitable for educational applications. In EDLAN, a number of personal computers are connected through an RS-485 global bus which carries the data transmission among the computers. CSMA/CD protocol is used to control the access of the global bus. The communications are controlled...

  • Simulation studies of routing algorithms for multicomputer systems

    Creator:
    Choi, Jangmin
    Abstract:
    Efficient routing of messages is critical to the performance of multicomputers. Many adaptive routing algorithms have been proposed to improve the network efficiency; however, they can make only short-sighted decisions to choose a channel for message routing because of limited information about network condition. The short-sighted decisions may cause unnecessary...

  • A performance study of multithreading

    Creator:
    Kwak, Hantak
    Abstract:
    As the performance gap between processor and memory grows, memory latency will be a major bottleneck in achieving high processor utilization. Multithreading has emerged as one of the most promising and exciting techniques used to tolerate memory latency by exploiting thread-level parallelism. The question however remains as to how effective...

  • The architecture of VIS multimedia extension

    Creator:
    Kwon, Young-Kyong
    Abstract:
    In the past, multimedia technology focused mainly on designing high quality audio and graphical imagery as well as providing adequate performance levels that the users demand for multimedia applications. However, the concept of multimedia has expanded into New-Media that involves variety use of multimedia data in consumer-oriented applications, such as...

  • Nonlinear neural control with power systems applications

    Creator:
    Chen, Dingguo
    Abstract:
    Extensive studies have been undertaken on the transient stability of large interconnected power systems with flexible ac transmission systems (FACTS) devices installed. Varieties of control methodologies have been proposed to stabilize the postfault system which would otherwise eventually lose stability without a proper control. Generally speaking, regular transient stability is...

  • The dynamic simultaneous multithreaded processor

    Creator:
    Ortiz-Arroyo, Daniel
    Abstract:
    This dissertation investigates diverse techniques to support multithreading in modern high performance processors. The mechanisms studied expand the architecture of a high performance superscalar processor to control efficiently the interaction between software-controlled and hardware-controlled multithreading. Additionally, dynamic speculative mechanisms are proposed to exploit thread-level-parallelism (TLP) and instruction-level-parallelism (ILP) on a...

  • Motion detection algorithm using wavelet transform

    Creator:
    Lee, Jeongmin
    Abstract:
    This thesis presents an algorithm that estimates motion in image sequence using wavelet transform. The motion detection is performed under unfavorable conditions of background movement, change of brightness, and noise. The algorithm is tolerant to brightness changes, noise, and small movement in the background. The false alarm rate of motion...

  • Analysis and modeling of GaAs MESFET's for linear integrated circuit design

    Creator:
    Lee, Mankoo
    Abstract:
    A complete Gallium Arsenide Metal Semiconconductor Field Effect Transistor (GaAs MESFET) model including deep-level trap effects has been developed, which is far more accurate than previous equivalent circuit models, for high-speed applications in linear integrated circuit design. A new self-backgating GaAs MESFET model, which can simulate low frequency anomalies, is...
