  • Student understanding of functions and the use of the graphing calculator in a college algebra course

    Creator:
    Averbeck, Patrick J.
    Abstract:
    The purpose of the study was to investigate students' learning of the function concept and the role of the graphing calculator in a College Algebra course. Differences between students with high symbolic manipulation skills. and students with low symbolic manipulation skills were also examined. On the basis of an algebraic...

  • On the enumeration of certain equivalence classes of Euler paths of full graphs

    Creator:
    Prothero, Stephen Kerron
    Abstract:
    This thesis treats the problem of enumerating equivalence classes of Euler paths of full graphs. A full graph is a complete, unordered, graph with no loops or repeated edges. Two Euler paths are equivalent if and only if one can be transformed into the other by a finite sequence of...

  • Drawing graphs nicely

    Creator:
    Palmer, Paul A.
    Abstract:
    A graph may he drawn in many different ways. We investigate how to draw a graph nicely, in the sense of being visually pleasing. We discuss the history of this field, and look at several algorithms for drawing graphs. For planar graphs this problem has been algorithmically solved: that is,...

  • Using the graphical method to solve linear programs

    Creator:
    Reeb, J. E. (James Edmund), 1951-, Leavengood, Scott A., and Oregon State University. Extension Service
    Abstract:
    A key problem faced by managers is how to allocate scarce resources among activities or projects. Linear programming, or LP, is a method of allocating resources in an optimal way. It is one of the most widely used operations research (OR) tools. It has been used successfully as a decision...

  • Graphical models for multivariate spatial data

    Creator:
    Irvine, Kathryn M.
    Abstract:
    In this thesis we focus on a graphical model for multivariate spatially correlated data--isomorphic chain graphs (ICG; Gitelman and Herlihy, 2007). We feel ICG allow flexibility for modeling spatial correlation and are intuitively appealing because each model has an associated graph that visually represents a complex multivariate system. We examine...
