  • Wide stripe, high power diode lasers

    Creator:
    Parson, Kevin J.
    Abstract:
    Typical power outputs of commercially available diode lasers are on the order of 5 milliwatts. This thesis discusses the growth, processing and fabrication of high power (lOO's of milliwatts) diode lasers. Devices were grown by Molecular Beam Epitaxy (MBE) and by Metal Organic Chemical Vapor Deposition (MOCVD). The MOCVD diode...

  • Web-based distributed applications for cytosensor

    Creator:
    Liew, Ji Seok
    Abstract:
    To protect the environment and save human lives, the detection of various hazardous toxins of biological or chemical origin has been a major challenge to the researchers at Oregon State University. Living fish cells can indicate the presence of a wide range of toxins by reactions such as changing color...

  • Weather influence on Loran-C

    Creator:
    Graulich, Markus Günter
    Abstract:
    The influence of weather on the long range radio navigation system Loran-C was investigated. The variables analyzed over a period of 255 days were: time differences (TDs), TD signal-to-noise ratios, TD standard deviations (measured at a fixed receiver location in Corvallis, Oregon), time interval numbers (TINOs) (measured at the transmitter...

  • Wavelet analysis as a signal processing method for multiresolution signal decomposition in natural resources applications

    Creator:
    Tu, De Yun
    Abstract:
    The purpose of this thesis is to apply the wavelet transform WT to multiresolution structures for analyzing the information content of images based on multiresolution signal decomposition of the wavelet representation. The advantage of the wavelet transform is the fact that it uses different building blocks than the Fourier's sines...

  • Voltage controller for a variable speed generation system

    Creator:
    Weigand, Claus H.
    Abstract:
    An important task of a Variable Speed Generation (VSG) system is the capability to maintain and control the terminal voltage at some desired value as determined by the reactive power dispatch strategy.The main objective is to design a sub-optimal fixed-parameter controller in the sense that constraints with respect to practical...

  • Voltage analysis of PWM inverter fed induction motors

    Creator:
    Al-Ghubari, Fahad H.
    Abstract:
    Adjustable Speed Drive (ASD) systems are widely used in industry to effectively improve process efficiency and control. Typically, an ASD system consists of a motor with its speed controlled by a power electronics converter via varying the amplitude and frequency of the input voltage. However, several abnormal insulation failures of...

  • VLSI implementation of adaptive BIT/serial IIR filters

    Creator:
    Badyal, Rajeev
    Abstract:
    A new structure for the implementation of bit/serial adaptive IIR filter is presented. The bit level system consists of gated full adders for the arithmetic unit and data latches for the data path. This approach allows recursive operation of the IIR filter to be implemented without any global interconnections, minimal...

  • VLSI design methodologies and computer tools

    Creator:
    Lim, Daniel
    Abstract:
    The rapid development of semiconductor technology and the increasing complexity of VLSI chips have prompted both the industry and the academic community alike to take an indepth look at the VLSI design problem. Many design methodologies have been proposed and associated computer-aided tools developed. This thesis is a study of...

  • Variable linear phase digital filters

    Creator:
    Acuna, Fernando R.
    Abstract:
    Linear phase variable filters that are obtained with a frequency transformation of the form cos(ω) = P(cos(W)) were analyzed, where P is a finite degree polynomial, ω is the prototype frequency and W is the transformed filter frequency. A new transformation of third order is proposed. The new variable filter...
