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...

On normalized multiplicative cascades under strong disorder

Creator:: Dey, Partha S. and Waymire, Edward C.
Abstract:: The purpose of this note is to provide a coupling of weak limits in distribution of sequence of (normalized) multiplicative cascade measures under strong disorder in terms of the extremes of an associated branching random walk, assuming i.i.d positive, non-lattice bond weights and a second moment condition. The solution is...

Sampling, feasibility, and priors in Bayesian estimation

Creator:: Chorin, Alexandre J., Lu, Fei, Miller, Robert N., Morzfeld, Matthias, and Tu, Xuemin
Abstract:: Importance sampling algorithms are discussed in detail, with an emphasis on implicit sampling, and applied to data assimilation via particle filters. Implicit sampling makes it possible to use the data to find high-probability samples at relatively low cost, making the assimilation more efficient. A new analysis of the feasibility of...

Eliminating flutter for clamped von Karman plates immersed in subsonic flows

Creator:: Lasiecka, Irena and Webster, Justin
Abstract:: We address the long-time behavior of a non-rotational von Karman plate in an inviscid potential flow. The model arises in aeroelasticity and models the interaction between a thin, nonlinear panel and a flow of gas in which it is immersed [6, 21, 23]. Recent results in [16, 18] show that...

Inequivalent Cantor sets in 𝑅³ whose complements have the same fundamental group

Creator:: Garity, Dennis J. and Repovš, Dušan
Abstract:: For each Cantor set C in R³, all points of which have bounded local genus, we show that there are infinitely many inequivalent Cantor sets in R³ with the complement having the same fundamental group as the complement of C. This answers a question from Open Problems in Topology and...

Metrics of positive scalar curvature and generalised Morse functions, Part II

Creator:: Walsh, Mark
Abstract:: The surgery technique of Gromov and Lawson may be used to construct families of positive scalar curvature metrics which are parameterised by Morse functions. This has played an important role in the study of the space of metrics of positive scalar curvature on a smooth manifold and its corresponding moduli...

A numerical study of coastal stratus cloud in a two-dimensional meso-scale model

Creator:: Lee, Tae Young
Abstract:: A two-dimensional numerical mesoscale model, which ic1udes radiative and turbulent transfers, has been constructed to study the formation, development and dissipation of coastal stratus cloud under an inversion. In the model, the delta-Eddington and emissivity approximations are used for the solar and thermal radiative transfers, respectively. K-theory parameterization is adopted...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Small group discussions in large lecture : connections between teacher facilitation and student participation

Creator:: Roth, Jennifer A. (Jennifer Albretsen)
Abstract:: An investigation was made to determine teacher facilitation techniques in large lecture physics classrooms that foster small group discussion. Video recordings of an introductory calculus-based physics class were taken for the 2008-2009 academic year at Oregon State University. These videos were analyzed to determine student participation in small group discussion...
