  • Wireless Charging System Using Inductive Coupling

    Creator:
    Waters, Allen T.
    Abstract:
    A wireless power transfer system using inductive coupling was designed and implemented as part of a three-member project team. The system uses coupled magnetic fields at a frequency of 606kHz to transfer electromagnetic energy from a charging base to the batteries of portable devices. It succeeded in transmitting power to...

  • Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

    Creator:
    Zanbaghi, Ramin
    Abstract:
    There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...

  • WebModeler: Modeling Human Hunting Induced Mammal Depletion in the Web

    Creator:
    Thenell, Tasman
    Abstract:
    The Amazon basin is a natural wonder of biodiversity that serves as one of the largest single carbon storage mechanisms in the world. For these reasons, preserving the Amazon and other similar forests is a worthy goal. Protecting these spaces is not possible without understanding the threats facing animal populations...

  • 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 sag and momentary interruption ride-through for adjustable speed drives

    Creator:
    van Zyl, Annabelle
    Abstract:
    The awareness of electric power quality has increased over the past decade as electronic equipment has become more susceptible to power disturbances. The most disruptive power disturbances are voltage sags and momentary interruptions and their effect on adjustable speed drives (ASDs) is studied in this thesis. Several solutions have been...

  • 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...
