  • Orb Web Vibrations: Modeling, Localization, and Measurement

    Creator:
    Otto, Andrew W.
    Abstract:
    The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

  • Rational Fuel Design for Low Temperature Internal Combustion Engines

    Creator:
    Daly, Shane R.
    Abstract:
    This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...

  • Data-Driven Environmentally Sustainable Product Design: A Shift Toward Increased use of Sustainable Design Activities in the Early Design Phase

    Creator:
    Ferrero, Vincenzo J.
    Abstract:
    Modern product design drives the boundaries of innovation by encompassing complex Design-for-X objectives, and the inclusion of multidimensional stakeholders. This growing complexity in product design has left design teams unequipped, as classical design theory is bounded by designer experience, expertise, and cognition. One novel approach to tackling product complexity is...

  • A design framework for identifying automation opportunities

    Creator:
    Nagel, Robert Lewis, 1982-
    Abstract:
    Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...

  • Towards a guided framework for innovative engineering through the generation and evaluation stages of concept design

    Creator:
    Oman, Sarah Kay
    Abstract:
    This work proposes a framework of concept generation and evaluation that takes into consideration the benefit of creativity and innovation in current market trends. By educating engineers in how to increase creativity in concept design and assess it quantitatively, the next generation of designers will be a step ahead of...

  • Performance and optimum design analysis/ computation for propeller type wind turbines

    Creator:
    Walker, Stel Nathan
    Abstract:
    Development of a performance analysis for propeller type wind turbines is presented. The analysis uses a strip theory approach that includes tip-loss and blade interference. A comparison is presented between analysis and test data. The comparison indicates that the analysis predicts wind turbine performance to an accuracy that is within...

  • 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...

  • Combustion mechanisms in wood fired boilers

    Creator:
    Tuttle, Kenneth Lewis
    Abstract:
    A program of research has been established at Oregon State University to study wood residue combustion using an experimental spreader-stoker combustor. This research was conducted to increase the understanding of combustion occurring in wood fired boilers. Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial experiments were conducted varying...
