  • Engineering design knowledge management and capture using a process overview document

    Creator:
    Zarins, Andis M.
    Abstract:
    An experiment was conducted to examine the possible impact of an engineering design and problem solving process overview document on knowledge management and capture. A process overview document was first created. Next, two multi-disciplinary design teams worked over a two-week span to develop concepts to address a problematic opportunity. One...

  • CFD Model Analysis and Validation for a Formula SAE Racecar

    Creator:
    LaFranchi, Alexander
    Abstract:
    This project examines the computational fluid dynamics (CFD) model used by Global Formula Racing (GFR) to simulate external aerodynamics for a Formula SAE racecar. It seeks to improve the accuracy of the existing model by changing mesh and physics model parameters. Accuracy of the model is quantified through comparison to...

  • Monitoring and diagnosis of a multi-stage manufacturing process using Bayesian networks

    Creator:
    Wolbrecht, Eric T.
    Abstract:
    This thesis describes the application of Bayesian networks for monitoring and diagnosis of a multi-stage manufacturing process, specifically a high speed production part at Hewlett Packard. Bayesian network "part models" were designed to represent individual parts in-process. These were combined to form a "process model", which is a Bayesian network...

  • Analysis, design, and implementation of a Formula SAE cooling system

    Creator:
    Theroff, Zachary
    Abstract:
    This project consists of the analysis, design, and manufacturing of the 2016 cooling system for Global Formula Racing’s combustion vehicle. Several water configurations were examined, using computational fluid dynamics (CFD) to estimate airflow and heat transfer calculations in MATLAB to estimate heat rejection through each concept. Data used to perform...

  • Utilizing the thermodynamic properties of E85 to increase the specific efficiency of a high specific output single cylinder Formula SAE engine

    Creator:
    Duncan, Derek N.
    Abstract:
    Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15%...

  • Distortion-induced fatigue cracking of girder-to-crossbeam connection

    Creator:
    Aljutaili, Dhari S.
    Abstract:
    Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

  • 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...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • Design of an automated system for imaging and sorting soil mesofauna

    Creator:
    Chamblin, Mike A.
    Abstract:
    Identification and population counts of soil mesofauna can be an important tool for soil ecologists to determine the soil biodiversity. Information provided from population counts can give insight to soil ecologists about the effects of human land use, monitoring soil and water health, benefits of soil biodiversity in agriculture, and...

  • Multi Objective Aerodynamic Design in Formula SAE

    Creator:
    Arscott, Phillip J.
    Abstract:
    This thesis examines the effect of aerodynamics on Formula SAE cars. Due to the different objectives of the Formula SAE events, an understanding of the car's complete aerodynamic design is necessary. Using a half car computational fluid dynamics (CFD) model, a series of sensitivity studies are conducted to determine trends...
