  • Dynamic simulation of robot manipulators

    Creator:
    Vora, Younus
    Abstract:
    A program has been written to investigate the dynamics of robot manipulators during task execution. The program simulates robot motion along a path specified by the user. A smooth trajectory is generated by interpolation in joint space. Forces and torques on actuators are calculated at intermediate points, using a recursive...

  • Boundaries of research : civilian leadership, military funding, and the international network surrounding the development of numerical weather prediction in the United States

    Creator:
    Harper, Kristine C.
    Abstract:
    American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...

  • Robust controller design for robotic manipulators with saturation

    Creator:
    Liang, Zuyang
    Abstract:
    The development of modern industries calls for the robotic manipulators with high speed and accurate tracking performance. Many authors have paid attention to robust control of robotic manipulators; however, only few authors have also considered the control problem of manipulators with power limitation. In this dissertation, the robotic manipulator is...

  • Understanding how Vietnamese make career decisions in the United States

    Creator:
    Do, Vinh The
    Abstract:
    This research explores the lived experiences and career decision making styles of three Vietnamese refugees in the United states. Since this study involves the lived experience of the participants pertaining to their everyday activities (i.e. living, making decision, and working in the United States), the phenomenological approach (Van Manen, 1990;...

  • Optimization of polynomial trajectories for robotic manipulators

    Creator:
    Yildirim, Yuksel
    Abstract:
    In this thesis, a method is presented to construct minimum-time robot trajectories for predefined Cartesian end-effector path in a workspace containing obstacles. The method is preferably applied to a geometric collision-free path of a SCARA robot by using the theories of Bezier, B-spline, and parabolic blending curves. The motion of...

  • Education of American research astronomers, 1876-1941

    Creator:
    Hall, Robert Dale, 1947-
    Abstract:
    The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

    Creator:
    Torosyan, Karine
    Abstract:
    This dissertation consists of two papers on International Trade topics. The first paper addresses the development of trade patterns between countries in transition and developed economies. The second paper focuses on the nonparametric estimation of the Knowledge-Capital model of multinationals. The first paper provides a framework for understanding patterns of...

  • An application of item response theory to the test of gross motor development

    Creator:
    Cole, Emily Lynne
    Abstract:
    The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The...

  • Effects of a resistance exercise program on activities of daily living of elderly women

    Creator:
    DeVries, Christine L.
    Abstract:
    The purpose of this study was to determine if a 5-month progressive-resistance exercise program would affect measures of activities of daily living (ADLs) and functional stability in elderly women. All subjects were ambulatory women, 80 to 93 years old, who lived in assisted-care facilities. Eight exercise and 7 control subjects...

    Long, Tulley A.
    Abstract:
    In an initial research proposal of December 1969, the scientists of the Coniferous Forest Biome (CFB), an ecosystem study centered in the Pacific Northwest and part of the larger International Biological Programme (IBP), expressed optimism that computer simulations and systems modeling could transform empirical knowledge of the carbon, water, and...
