  • Liquid crystal thermography : a new system for breast cancer detection

    Creator:
    Bichara, Kamal Fouad
    Abstract:
    A liquid crystal thermographic technique was developed for application to several problems in clinical medicine and physiology. The procedure was inexpensive, rapid, simple, versatile and acceptable to patients. Investigators in the past have used cholesteric liquid crystals for thermography but their use was limited to research in the medical field...

  • Investigation of electric field-induced optical absorption changed in CdS

    Creator:
    Shimoda, Raynor Yoichi
    Abstract:
    The feasibility of using the Franz-Keldysh effect in practical light intensity controlling devices was investigated. Reverse-biased diodes made from CdS were implemented to obtain high electric fields necessary for the effect. The three types of diodes studies were: MIS, metal-semiconductor barrier, and p⁺-n heterojunction. An expression for the change in...

  • 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...

  • 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...

  • Sliding-mode control of the super maneuverable aircraft

    Creator:
    Koo, Chang Sul
    Abstract:
    In this thesis, A nonlinear methodology for the control of the highly maneuverable, high performance aircraft HARV (F-18) is studied by using sliding-mode control (SMC). This control law, which takes a continuous function when the input constraints are not considered, satisfies the reachability condition by which concerned states are driven...

  • Design techniques for low-voltage analog-to-digital converter

    Creator:
    Chang, Dong-Young
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low-voltage conditions. There are several well-known techniques to bypass the problem. These approaches include: (1)...

  • Micro data flow processor design

    Creator:
    Chang, Chih-ming
    Abstract:
    Computer has evolved rapidly during the past several decades in terms of its implementation technology; it's architecture, however, has not changed dramatically since the von Neumann computer(control flow) model emerged in the 1940s. One main reason is that the performance for this kind of computers was able to satisfy the...

  • A channelized digital receiver design for UWB sytems in a multipath indoor environment

    Creator:
    Chang, Yuhao
    Abstract:
    This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...

  • The low-power design of prefix adder

    Creator:
    Chang, Che-jen
    Abstract:
    Minimizing the dynamic power consumption of a circuit is becoming a more and more important issue for digital circuit design in the age of portable electronics. Among all the arithmetic circuits, addition is the most fundamental operation. Therefore, designing low power adder is an important and necessary research area. In...

  • Tolerating processor-memory performance gap

    Creator:
    Lai, Shih-Chang
    Abstract:
    While the performance gap between microprocessors and main memory is ever increasing each year, cache memory has been a bridge to alleviate this discrepancy. In this thesis proposal, we introduce three techniques to tolerate this processor and memory speed imbalance. First, we propose the bloom filter scheme to identify which...
