  • Deep ultraviolet solid-state laser development

    Creator:
    Dutton, David A. (David Adam)
    Abstract:
    There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

  • Fiber Bragg grating-tunable diode laser

    Creator:
    Ericksen, Doug
    Abstract:
    Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

  • Distributed temperature sensing with neodymium-doped optical fiber

    Creator:
    Lounsbury, Jimson S.
    Abstract:
    Polymer electrolyte membrane (PEM) fuel cells are being studied for use as high efficiency power plants in alternative fuel vehicles. To maintain high efficiency the operating temperatures of the membranes in these fuel cells must be closely monitored and controlled. However, the environment inside of the fuel cell is not...

  • Fabrication and characterization of thin-film electromagnetic coils and heaters for microchannel applications

    Creator:
    Dehuff, Nicole L.
    Abstract:
    The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State University. The two MECS devices developed, capture dots and transparent thin-film heaters (TTFHs), require unique process development for successful...

  • New configurations of bandpass filters in single and multilayer environment

    Creator:
    Gururajan, Kala
    Abstract:
    Mobile and telecommunication industry has experienced tremendous growth in the recent past. Miniaturization and increased functionality have become necessary for all passive components in the system. Bandpass filters are critical passive components in any communication system and the existing designs in the crucial 1-10 GHz bandwidth suffer many drawbacks. For...

  • Influence of adjustable speed drive on induction motor fault detection using stator current monitoring.

    Creator:
    Al-Shahrani, Ali
    Abstract:
    The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected. Current signature...

  • Partitioning-Guided K-Means for Effective Empty Cluster Resolution in Extreme Model Compression

    Creator:
    Huang, Tianhong
    Abstract:
    Compactness in deep learning can be critical to a model’s viability in low-resource applications, and a common approach to extreme model compression is quantization. We consider Iterative Product Quantization (iPQ) with Quant-Noise [Fan et al., 2020] to be state-of-the-art in this area, but this quantization framework suffers from preventable inference...

  • Fabrication and characterization of p-type CuO / n-type ZnO heterostructure gas sensors prepared by sol-gel processing techniques

    Creator:
    Ravichandran, Ram
    Abstract:
    Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...

  • Leaf shape recognition via support vector machines with edit distance kernels

    Creator:
    Sinha, Shriprakash
    Abstract:
    Edit distances are a well-established technique for classification problems. They have been employed successfully in many classification problems including chromosome classification and hand-written digit recognition. Virtually all machine learning algorithms represent the objects to be classified as vectors of features. However, edit distances provide only a measure of the difference...

  • Design and analysis techniques for nano-joule ADCs and sampling linearity

    Creator:
    Brown, Thomas (Thomas William)
    Abstract:
    Two aspects of ADC system performance are addressed in this work. First, the combination of the ADC and its associated reference are co-designed for an energy constrained remote sensing system. Second, sampling linearity is mathematically analyzed as a function of frequency to provide enhanced understanding into an ADC's requisite sampling...
