  • ATRIAS 1.0 & 2.1 : enabling agile biped locomotion with a template-driven approach to robot design

    Creator:
    Grimes, Jesse A.
    Abstract:
    Practical bipedal robots need to be simultaneously efficient, robust, and versatile machines, but designing robots dynamically capable of these demands has been a significant bottleneck. We designed ATRIAS to be a highly dynamic biped capable of both walking and running untethered in real environments. To meet these goals, ATRIAS is...

  • From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

    Creator:
    Hubicki, Christian M.
    Abstract:
    Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

  • Dynamics and control for spring-mass legged robots

    Creator:
    Vejdani Noghreiyan, Hamid Reza
    Abstract:
    The objective of this study is to propose control strategies for legged robots to walk and run naturally like humans and animals. To achieve this goal, we use the spring-mass model for the legged robots to be able to create the same dynamics in the leg as humans and animals....

  • Force and impulse control for spring-mass running

    Creator:
    Koepl, Devin N.
    Abstract:
    We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

  • Factors that motivate Latino students to pursue higher education in selected colleges in the state of Oregon

    Creator:
    Meza Discua, José Luis
    Abstract:
    Latinos are the largest and most rapidly growing ethnic minority in the United States, and they have the highest dropout rates of any major ethnic group in the country (U.S. Department of Labor, 2003). Latinos' educational attainment is consistently lower than that of other students (Gandara, 2008). The majority of...

  • Mercury bioaccumulation in remote subalpine lakes : assessing the influence of invasive trout on salamanders

    Creator:
    Pfleeger, Adam
    Abstract:
    Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...

  • Environmental Remote Sensing with Unmanned Aircraft Systems

    Creator:
    Burnett, Jonathan D.
    Abstract:
    Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....

  • Anthropological case studies of religious syncretism in Bolivia

    Creator:
    Lord, Jonathan
    Abstract:
    Religious histories have always appropriated pre-existing symbol systems of religion into newer forms, often with the goal in mind to acculturate a population into a new cultural setting to reach a desired status quo of society. The problem with acculturation theory is that it is filled with teleological and quantitative...

    Creator:
    Day, Jonathan
    Abstract:
    The results of an investigation into carrier dynamics in several novel functionalized and solution-processable pentacene and anthradithiophene derivatives are reported. Measurements were made of real-time photoresponse of polycrystalline thin films of these materials to ultrafast laser pulses, on picosecond to microsecond time-scales, as well as measurements of dark current and...

  • Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

    Creator:
    Hooper, Samuel
    Abstract:
    Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...
