  • Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

    Creator:
    Kriett, Phillip Oliver
    Abstract:
    Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...

  • Performance characterization of an integrated microscale hydrogen combustor recuperator and oil heat exchanger

    Creator:
    Haley, David B. (David Brien)
    Abstract:
    Experiments on a novel, microscale hydrogen combustor heat exchanger (µCHX) are presented in this thesis. The µCHX has been designed to efficiently transfer thermal energy to a heat transfer fluid for use in desorption of hydrogen from a metal hydride storage system of a hydrogen-powered fuel cell vehicle. The experimental...

  • Enabling safety-informed design decision making through simulation, reasoning and analysis

    Creator:
    Jensen, David Charles
    Abstract:
    While many organizations claim to "put safety first," safety is rarely considered early in the design process when system-level architectural decisions are made. Instead, system design follows an abstraction-to-detail process to first meet functional and then performance requirements. Following this process, safety assurance occurs in the later stages of design...

  • Understanding Designer Mental Models to Support Computer Directed Analogical Design

    Creator:
    Arlitt, Ryan M.
    Abstract:
    Analysis of alternative concepts has a significant impact on design project outcomes, and yet many design teams fail to consider a significantly broad range of conceptual solutions. Within the realm of conceptual design exists a technique called design by analogy (DBA) -- the practice of reapplying old solutions to new...

  • Systematic design of biologically-inspired engineering solutions

    Creator:
    Nagel, Jacquelyn Kay
    Abstract:
    Biological organisms, phenomena and strategies, herein referred to as biological systems, provide a rich set of analogies that can be used to inspire engineering innovation. Biologically-inspired, or biomimetic, designs are publicly viewed as creative and novel solutions to human problems. Moreover, some biomimetic designs have become so commonplace that it...

  • Potential of Genetic Algorithms for Design of Liquid Cooled Heat Sinks Fabricated Using Additive Manufacturing

    Creator:
    Dokken, Connor B.
    Abstract:
    The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...

  • Optimal Experimental System Design

    Creator:
    Mohseni, Seyed Alireza
    Abstract:
    Physical experimentation in various scientific and engineering areas continues to be a useful and often necessary approach that is applied in research, development, and for general problem solving. The experimental design process however, is iterative and often involves trial and error. Alternative designs are proposed and evaluated on cost and...

  • Analysis of the Effects of Combustion Products on Forced Ignition and Turbulent Flame Propagation

    Creator:
    Bonebrake, Jonathan M.
    Abstract:
    Practical combustion devices frequently rely upon forced ignition of turbulent fuel/oxidizer mixtures that also contain the product species of combustion. Examples of this include engines that use exhaust gas recirculation (EGR), inter-turbine burners in aircraft engines, and other systems the utilize staged combustion. In this work, the effects of major...

  • Efficient Algorithms for Solving the Median Problem on Real Road Networks

    Creator:
    Ghanbartehrani, Saeed
    Abstract:
    Location theory is a well-established and active research area. The main objective in location theory is to find the best locations for facilities to meet supply and demand constraints and minimize total cost. The median problem (also known as the 1-median problem) is a special case in location analysis that...

  • Reduced order multi-legged mathematical model of cockroach locomotion on inclines

    Creator:
    Peterson, Delvin E.
    Abstract:
    While the locomotion performance of legged robots over flat terrain or known obstacles has improved over the past few decades, they have yet to equal the performance of their animal counterparts over variable terrain. This work analyzes a multi-legged reduced order model of cockroach locomotion on variable slopes which will...
