  • Radiation losses in microstrip circuits

    Creator:
    Lo, Sui-Sang
    Abstract:
    The purpose of this study is to investigate radiation losses in microstrip circuits. Expressions are derived to evaluate the radiation resistances (or conductances) for single terminated, open and short-circuited lines. The quality factor Q of open and short-circuited stubs is evaluated. An analytical procedure is formulated to evaluate the radiation...

  • Compartmental analysis of the immune system

    Creator:
    Lawrence, Karen
    Abstract:
    A compartmental model of the immune system is simulated. Chapter I discusses the importance of such a model, reviews past immune system models, and summaries the immunological theory the model is based upon. In Chapter II, the compartmental representation of the immune system is developed from immunological and physiological theory....

  • The design of delta-sigma modulators for multi-standard RF receivers

    Creator:
    Liu, Mingliang
    Abstract:
    The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this request is the use of Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic range requirements for digital signal processing, and...

  • Identification of synchronous machine parameters

    Creator:
    Shaban, Ali Omar
    Abstract:
    The synchronous machine is an essential component of a power system and determination of its parameters accurately is an important task in securing adequate modes of operation through certain control strategies. An estimation technique based on the Powell algorithm was evaluated for the identification of these parameters on the basis...

  • Low-power double-sampled delta-sigma modulator for broadband applications

    Creator:
    Shen, Weilun
    Abstract:
    High speed and high resolution analog-to-digital converter is a key building block for broadband wireless communications, high definition video applications, medical images and so on. By leveraging the down scaling of the latest CMOS technology and the noise shaping properties, delta-sigma (ΔΣ) ADCs are able to achieve wide-band operation and...

  • Wideband discrete-time delta-sigma analog-to-digital converters with shifted loop delays

    Creator:
    Meng, Xin
    Abstract:
    Low-distortion architecture is widely used in wideband discrete-time switched-capacitor delta-sigma ADC design. However, it suffers from the power-hungry active adder and critical timing for quantization and dynamic element matching (DEM). To solve this problem, this dissertation presents a delta-sigma modulator architecture with shifted loop delays. In this project, shifted loop...

  • Compensation techniques for cascaded delta-sigma A/D converters and high-performance switched-capacitor circuits

    Creator:
    Sun, Tao
    Abstract:
    This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC circuits. A CDS technique...

  • Implementation of an Ethernet Local Area Network board for the MacIntosh II system

    Creator:
    Yoo, Tae-On
    Abstract:
    The purpose of this study was to design and to implement a practical Ethernet Local Area Network (LAN) board for the Macintosh II computer system. A survey of the literature provided a general definition of LANs, a reference model for network layers, specifications for an Ethernet LAN, and information on...

  • Cursive script recognition using a dynamic time warping method

    Creator:
    Koehler, Loren M.
    Abstract:
    This thesis is concerned with the problem of achieving accurate recognition rates for Cursive Script Recognition (CSR). Cursive Script Recognition is difficult due to writer variations such as script formation and time non-linearities. This research entailed analysis and implementation of a Cursive Script word-level Recognition system using Dynamic Time Warping...
