  • Mathematical knowledge for teaching proof

    Creator:
    Lesseig, Kristin
    Abstract:
    The purpose of this study was to detail mathematical knowledge that supports the work of teaching proof and to investigate how such knowledge is evidenced in professional development (PD). To advance the construct of mathematical knowledge for teaching (MKT) in the context of proof, I developed a framework of MKT...

  • Mathematical treatment and simulation of methane hydrates and adsorption models

    Creator:
    Medina, Francis Patricia
    Abstract:
    In this dissertation we develop mathematical treatment for two important applications: (i) evolution of methane in coalbeds with the associated phenomena of adsorption, and (ii) formation of methane hydrates in seabed. We use simplified models for (i) and (ii) since we are more interested in qualitative properties of the solutions...

  • Mathematical approaches to the physics of mesoscale oceanography

    Creator:
    Early, Jeffrey J.
    Abstract:
    The long-term evolution of Gaussian eddies is studied in an equivalent barotropic model using both linear and nonlinear quasi-geostrophic theory in an attempt to understand westward propagating satellite altimetry tracked mesoscale eddies. By examining both individual eddies and a large basin seeded with eddies, it is shown that long term...

  • Reduced order multi-legged mathematical model of cockroach locomotion on inclines

    Creator:
    Peterson, Delvin E.
    Abstract:
    While the locomotion performance of legged robots over flat terrain or known obstacles has improved over the past few decades, they have yet to equal the performance of their animal counterparts over variable terrain. This work analyzes a multi-legged reduced order model of cockroach locomotion on variable slopes which will...

  • Three dimensional electromagnetic FDTD simulation of general lossy structures with nonuniform grid spacing

    Creator:
    Falconer, Maynard C.
    Abstract:
    A new second order accurate nonuniform grid spacing technique which does not depend on supraconvergence is developed for Finite Difference Time Domain (FDTD) simulation of general three dimensional structures. The technique is useful for FDTD simulations of systems which require finer details in small regions of the simulation space by...

  • A mathematical modeling framework for scheduling and managing multiple concurrent tasks

    Creator:
    Shakeri, Shakib
    Abstract:
    Occurrence of human error in highly complex systems, such as a cockpit, can be disastrous and/or overwhelmingly costly. Mismanagement of multiple concurrent tasks has been observed by researchers to be a type of repetitive human error in previous studies of accidents and incidents. This error may occur in the form...

  • Asymptotic convergence technique and executive concept for steady state process systems analysis

    Creator:
    Kwon, Young Jin
    Abstract:
    The first part of this work presents an executive system for steady state process systems analysis. The executive is developed to promote maximum flexibility, generality and a high degree of man-machine interaction by allowing the user to write a Fortran main calling program which permits special logic and control to...

  • Mathematical modeling and the control of immune processes with application to cancer

    Creator:
    Lee, Kwon Soon
    Abstract:
    A foundation for the control of tumors is presented, based upon the formulation of a realistic, knowledge-based mathematical model of the interaction between tumor cells and the immune system. The parametric control variables relevant to the latest experimental data, e.g., the sigmoidal dose-response relationship and Michaelis-Menten dynamics, are also considered....

  • A mathematical model for adsorptive bubble-separation processes

    Creator:
    T'ang, Li
    Abstract:
    Adsorptive bubble-separation processes are used to remove adsorptive contaminants from wastewater. A mathematical model was developed for the adsorptive bubble separation processes in a countercurrent column. The model included an assumption that linear adsorption of the solute occurred on the gas bubbles. Predictions indicated that aqueous column height has less...
