  • Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

    Creator:
    Casey, Sean (Sean Michael)
    Abstract:
    Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

  • Assessing Mass Diffusion Modeling in Premixed Flames

    Creator:
    Fillo, Aaron J.
    Abstract:
    Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

  • Modeling and control of a biologically inspired compliant structure

    Creator:
    Ray, Cody W.
    Abstract:
    We hypothesize that the extraordinary maneuverability and efficiency of bats in flight are in part due to the compliant nature of their wing structures. We utilize the parameters of bat bones measured by biologists to create a biologically inspired model of a flapping system consisting of a rotating hub actuator...

  • Exploring experimental test stand design and operation within a system reliability research methodology

    Creator:
    Koopmans, Michael, 1986-
    Abstract:
    In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

  • The wave energy resource of the US Pacific Northwest

    Creator:
    Lenee-Bluhm, Pukha
    Abstract:
    The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...

  • Foam-Core Meniscus Coating and Diffusion Bonding for Energy Applications

    Creator:
    Saranam, Venkata Rajesh
    Abstract:
    In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...

  • Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

    Creator:
    Mohammadi, Mahshid
    Abstract:
    A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

  • Bi-criteria group scheduling with learning in hybrid flow shops

    Creator:
    Bozorgirad, Mir Abbas
    Abstract:
    In this research, a bi-criteria group scheduling problem is investigated in hybrid flow shop (HFS) environments, where the parallel machines in each stage are unrelated, meaning not identical. The objective of the problem is to minimize a linear combination of the total weighted completion times as a means of complying...

    Abstract:
    In this research, a bi-criteria batching and scheduling problem is investigated in hybrid flow shop environments, where unrelated-parallel machines are run simultaneously with different capacities and eligibilities in processing, in some stages. The objective is to simultaneously minimize a linear combination of the total weighted completion time and total weighted...
