A Parallelized And Layered Model For The Shallow-Water Equations, Alexander Stevens
A Parallelized And Layered Model For The Shallow-Water Equations, Alexander Stevens
All Theses
An energy- and enstrophy-conserving and optimally-dispersive numerical scheme for the shallow- water equations is accelerated through implementation in the GPU environment. Previous research showed the viability of the numerical scheme under standard shallow-water test cases, but was limited in applications by computation time constraints. We overcome these limitations by paral- lelizing the numerical computation in the GPU environment. We also extend the capabilities of the implementation to support not just a single shallow-water layer, but multiple. These improvements significantly expand the range of tests that can be used to exercise the model, and enable better understanding of the power of …

Numerical Study Of Laminar Flow In A Suddenly Expanding Channel, Murodil Madaliev
Numerical Study Of Laminar Flow In A Suddenly Expanding Channel, Murodil Madaliev
Scientific-technical journal
The article presents the results of a numerical study of the flow structure in a flat channel in the zone of its sudden expansion in the form of a ledge. The calculations are based on the numerical solution of a system of non-stationary equations using Navier-Stokes. The results of the longitudinal velocity profiles in various sections of the channel after the ledge are obtained. For the difference approximation of the initial equations, the control volume method was used, and the relationship between velocities and pressure was found using the SIMPLE procedure. For the numerical solution of this problem, the McCormack …
Mathematicians' Beliefs, Instruction, And Students' Beliefs: How Related Are They?, Rachel L. Rupnow
Mathematicians' Beliefs, Instruction, And Students' Beliefs: How Related Are They?, Rachel L. Rupnow
Faculty Articles, Papers, and Other Scholarship
It is generally accepted that teachers' beliefs impact their instructional choices, but characterizations of that relationship are limited in college settings. Furthermore, examinations of instructor beliefs, instruction, and student beliefs together in one setting are rarely described. Based on interviews with two Abstract Algebra instructors, classroom video from three units of instruction, and survey and interview data from students in the classes, this paper examines instructors' stated beliefs, ways these beliefs manifested in their teaching, and students' beliefs across the course. Both instructors made curricular choices clearly aligned with their stated views of the nature of mathematics, learning, and teaching. …
Optimal Design Problems With State Constraints, Nha Van Tran
Optimal Design Problems With State Constraints, Nha Van Tran
LSU Doctoral Dissertations
This thesis focuses on constrained optimization problems with constraints on the state variables. When the constraints involve partial differential equations or variational inequalities, the optimization problem is also known as Mathematical Programs with Equilibrium Constraints. First, we applied active-set properties of optimal solutions to transform variational inequality constraints into partial differential equation constraints and devised an active-set method which allowed us to solve the optimization problems using the adjoint approach. We extended our approach to evolution problems with constraints on the trajectory of the state variable, such as the irreversibility condition in fracture mechanics. We implemented a gradient descent algorithm …

Level And Gorenstein Projective Dimension, Laila Awadalla, Thomas Marley
Level And Gorenstein Projective Dimension, Laila Awadalla, Thomas Marley
Department of Mathematics: Faculty Publications
We investigate the relationship between the level of a bounded complex over a commutative ring with respect to the class of Gorenstein projective modules and other invariants of the complex or ring, such as projective dimension, Gorenstein projective dimension, and Krull dimension. The results build upon work done by J. Christensen [7], H. Altmann et al. [1], and Avramov et al. [4] for levels with respect to the class of finitely generated projective modules.
The concept of level in a triangulated category, first defined by Avramov, Buch- weitz, Iyengar, and Miller [4], is a measure of how many mapping cones …
