An Examination of the Impact of Successive and Non-Successive Geometry Classes on High School Student Achievement

Sugg, Steven (University of Oregon, 2012)

This study examines the impact of successive versus non-successive scheduling of mathematics courses on the achievement of ninth-grade students in a suburban Oregon high school. The Oregon Assessment of Knowledge and Skills ...
Lines and Conics in a Family of Quartic Surfaces

Richter, Karl (University of Oregon, 2023-05)

This thesis is primarily concerned with the fact that the general quartic surface does not contain a line or a conic section. More formally, the set of quartic surfaces containing lines or conic sections has measure ...
On Local Mechanical Properties of Thin Pressurized Shells with Combined Geometric and Material Anisotropies

Sun, Wenqian (University of Oregon, 2024-01-09)

Thin elastic shells are ubiquitous in nature. Indentation measurements (i.e., poking) provide a useful way for probing mechanical properties of these shell structures. While spherical and cylindrical shells made of isotropic ...
Uniqueness of Conformal Ricci Flow and Backward Ricci Flow on Homogeneous 4-Manifolds

Bell, Thomas (University of Oregon, 2013-10-03)

In the first chapter we consider the question of uniqueness of conformal Ricci flow. We use an energy functional associated with this flow along closed manifolds with a metric of constant negative scalar curvature. Given ...
