  • Digital stabilizer for brushless doubly-fed machine

    Creator:
    Krishnan, Sheela
    Abstract:
    The exceptional feature of the brushless doubly-fed machine is the lack of need for frequent replacement of brushes. The inherent instability of this machine has to be overcome for its application in adjustable speed drives and variable speed generation systems. Specific objectives were: to study the characteristics of the machine...

  • A microprogramming learning system

    Creator:
    Mammen, M. Ninan
    Abstract:
    A microprogramming teaching tool was designed and implemented. This tool was based on the Am 2900 bitslice microprocessor family. It provides tools for understanding software development for a simple bitslice microprocessor.

  • Speech deconvolution using Gaussian pulses

    Creator:
    Asadi, Mohammad Ayman O.
    Abstract:
    This dissertation introduces a new idea for frequency domain deconvolution of speech signals. The idea is to approximate a unit sample by a Gaussian pulse. The deconvolution is performed by designing a glottal inverse filter that will estimate the excitation of the vocal tract. Then, the excitation will be used...

  • Frequency domain deconvolution

    Creator:
    Tan, Hin Leong
    Abstract:
    Frequency domain design of deconvolution filters is studied using Fast Fourier Transform. Filters for both the spike and the Gaussian reflector wavelet are obtained. True deconvolution filters are infinitely long IIR filters, and frequency domain analysis is an effective way of finding its optimum finite length approximation for an arbitary...

  • A survey of optimal frequency domain deconvolution methods

    Creator:
    Gamage, Gayani N. K.
    Abstract:
    The resolution of multiple overlapped reflections is achieved by designing inverse filters using frequency domain deconvolution. A careful study reveals a number of problems involving frequency domain design of spike inverse filters. These include the presence of noise and aliasing in both the filter response and its output resulting from...

  • 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...

  • Analysis and Design of Low Voltage LC Oscillators and their Application to Wireless Sensor Networks

    Creator:
    Guha Roy, Ankur
    Abstract:
    This dissertation focuses on the analysis, design, and application of inductor-capacitor (LC) oscillators for wireless sensor networks (WSNs). First an analysis and design optimization approach for enhanced swing, low power CMOS LC oscillators is presented. A phasor based analysis is used for determining the amplitude and phase noise of these...

  • An adaptive pitch axis autopilot design for an unstable nonminimum phase pitch axis model

    Creator:
    Chen, Long Ren
    Abstract:
    An adaptive pitch axis autopilot design procedure is presented. The design procedure is applicable to both stable and unstable pitch axis models and to those having nonminimum phase. The design approach assumes the adaptive autopilot is activated after achieving level flight. It is shown a rate-feedback compensator can be designed...

  • Recognizing human group activities in video through mining optimal features

    Creator:
    Amer, Mohamed R.
    Abstract:
    Given a video, we would like to recognize group activities, localize video parts where these activities occur, and detect actors involved in them. To this and, we propose a novel, mid-level feature, called control point, for representing group activities. The control points are aimed at summarizing visual cues, lifting from...
