  • On the Topologies of Moduli Spaces of Polygons: A Taxonomic Approach

    Creator:
    Krughoff, Stephen A.
    Abstract:
    Consider a polygon lying in the Euclidean plane with labeled edge lengths. The moduli space of polygons is the space of all polygons with the same labeled edge lengths, modulo orientation preserving isometries. It is well known that this space is generically a smooth manifold. For certain combinations of edge...

  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

  • Modelling Development of Opinion Matrices Over Time

    Creator:
    Oostrom, Martijn L.
    Abstract:
    Given an initial opinion matrix in which every member of a population gives an opinion score of all the members in a population, natural questions to ask could be regarding what happens to those opinions over time, both in forward time and in backward time. While what happens over time...

  • Probabilities of voting paradoxes with three candidates

    Creator:
    McDonald, Leslie M.
    Abstract:
    Pardoxes in voting has been an interest of voting theorists since the 1800's when Condorcet demonstrated the key example of a voting paradox: voters with individually transitive rankings produce an election outcome which is not transitive. With Arrow's Impossibility Theorem, the hope of finding a fair voting method which accurately...

  • 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...

  • Exploring maize pollen with microscopy: confocal, fluorescence and time-lapse imaging

    Creator:
    Hartman, Rogue D. J.
    Abstract:
    Pollen, the male product of the flower, is a crucial component in plant reproduction, as it transmits the sperm cells to the female structures, enabling fertilization and subsequent seed production. A major transition of the pollen life cycle, triggered upon pollination of female floral tissue, is from a dormant pollen...
