  • Development of a posture prediction model

    Creator:
    Dendamrongvit, Thidarat
    Abstract:
    Biomechanical models have been used in designing human work environments to evaluate potential risks to workers before a work environment is constructed. In order for work environments to be modeled correctly, most biomechanical models require as input, an accurate body posture of the worker. This information can be obtained by,...

  • Modeling of Wave Energy Converter via Instantaneous Frequency

    Creator:
    Kim, Inyong
    Abstract:
    A multidisciplinary perspective is necessitated for the analysis of wave energy conversion systems, spanning hydrodynamics, mechanics, electric power, and control systems. The complexity inherent in these scientific domains poses challenges for unified analysis. This paper addresses these challenges by connecting various domains through the application of circuit theory, characterizing the...

  • Radiation effects in compound semiconductor heterostructure devices

    Creator:
    Sarkar, Aveek, 1974-
    Abstract:
    Radiation studies were performed on compound semiconductor heterostructure devices. The objective was to understand the degradation processes caused by the exposure of these devices to radiation. Preliminary experiments were focussed on studying the degradation phenomenon in single heterojunctions and single quantum wells. It was found that ionizing radiation like gamma...

  • Influence of macro-roughness on tsunami runup & forces

    Creator:
    Bridges, Kerri-Jane
    Abstract:
    This thesis is comprised of a manuscript based on a laboratory experiment run in the Tsunami Wave Basin as part of a research project funded by the Network for Earthquake Engineering Simulation called Housesmash. The purpose of the experiment was to better understand the role of the urban environment, represented...

  • A practical approach to model the behavior of a metal-plate-connected wood truss system

    Creator:
    Li, Zhong
    Abstract:
    Metal-plate-connected (MPC) trusses have traditionally been designed based on a tributary load distribution and a simplified truss model. This design method ignores the load-sharing and composite action in MPC roof truss systems, the semi-rigidity of MPC joints, and joint eccentricity. The main objective of this study was to provide a...

  • Performance Analysis of a Utility-Scale Wave Energy Converter

    Creator:
    May-Varas, Nicholas A.
    Abstract:
    A six degree of freedom (6DOF) point-absorber wave energy converter (WEC) called LUPA is being developed at Oregon State University. This research focused on analyzing a full- scale LUPA, called LUPA20, to answer the following questions: 1) How does a full-scale WEC perform due to various factors; 2) What are...

  • Toward wave energy in Oregon : predicting wave conditions and extracted power

    Creator:
    Oskamp, Jeffrey A.
    Abstract:
    Knowledge of wave conditions in nearshore regions supports the development of ocean wave energy technology by providing wave climatology for device design considerations, and power output estimates. By modeling wave transformation over the continental shelf, wave conditions were predicted in nearshore regions where potential wave energy conversion sites are located....

  • Simulations of geckos dry adhesion system

    Creator:
    Hu, Congcong
    Abstract:
    Simulation models were developed to explore the reversible nature of gecko dry adhesion system. The central idea of this model is that even with a small moment imparted on the contact tip, the seta can be easily ad-adhered. It is shown that this contact condition is very sensitive, but can...

  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • Laboratory observations of tsunami runup on a complex 3D bathymetry using PIV

    Creator:
    Ichikawa, Shingo
    Abstract:
    This thesis presents the details of a large-scale laboratory experiment to study the runup velocity on a complex 3D bathymetry. The PIV measurements including the instrumental setup, the recording procedure, and the image processing are presented. Tsunami inundation directly affects the coastal population and is one of the most important...
