(R1494) Approximate Solutions Of The Telegraph Equation, Ilija Jegdić
(R1494) Approximate Solutions Of The Telegraph Equation, Ilija Jegdić
Applications and Applied Mathematics: An International Journal (AAM)
In this paper the initial boundary value problems for the linear telegraph equation in one and two space dimensions are considered. To find approximate solutions, a recently proposed optimization-free approach that utilizes artificial neural networks with one hidden layer is used, in which the connecting weights from the input layer to the hidden layer are chosen randomly and the weights from the hidden layer to the output layer are found by solving a system of linear equations. One of the advantages of this method, in comparison to the usual discretization methods for the two-dimensional linear telegraph equation, is that this …
An Algorithm For Biobjective Mixed Integer Quadratic Programs, Pubudu Jayasekara Merenchige
An Algorithm For Biobjective Mixed Integer Quadratic Programs, Pubudu Jayasekara Merenchige
All Dissertations
Multiobjective quadratic programs (MOQPs) are appealing since convex quadratic programs have elegant mathematical properties and model important applications. Adding mixed-integer variables extends their applicability while the resulting programs become global optimization problems. Thus, in this work, we develop a branch and bound (BB) algorithm for solving biobjective mixed-integer quadratic programs (BOMIQPs). An algorithm of this type does not exist in the literature.
The algorithm relies on five fundamental components of the BB scheme: calculating an initial set of efficient solutions with associated Pareto points, solving node problems, fathoming, branching, and set dominance. Considering the properties of the Pareto set of …
Modeling Cherenkov Light Detection Timing For The Very Energetic Radiation Imaging Telescope Array System, Keilan Finn Ramirez
Modeling Cherenkov Light Detection Timing For The Very Energetic Radiation Imaging Telescope Array System, Keilan Finn Ramirez
Physics
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is an array of four 12-meter telescopes which use the Imaging Atmospheric Cherenkov Technique to conduct high-energy gamma-ray astronomy. VERITAS detects magnitude and location information associated with Cherenkov light, and uses this information to indirectly observe gamma-rays through a software reconstruction process. VERITAS also records timing information corresponding to Cherenkov light detection, and this additional information could theoretically be incorporated into the reconstruction process to improve the accuracy of gamma-ray observations. The first step to including timing information is to understand when Cherenkov light detection would be expected from a known …

Grid Homology Invariants For Singular Legendrian Links, Richard Michael Shumate
Grid Homology Invariants For Singular Legendrian Links, Richard Michael Shumate
Graduate Theses and Dissertations
If $\Lambda_{1}^{\ast}$ and $\Lambda_{2}^{\ast}$ are two oriented singular Legendrian links that are Legendrian isotopic, we first construct front diagram representations of $\Lambda_{1}^{\ast}$ and $\Lambda_{2}^{\ast}$ that have a natural allowable singular gird diagram associated to them. These allowable singular grid diagrams will always correspond to singular Legendrian links. The grid Legendrian invariants, $\lambda^{\pm}$, in the nonsingular grid homology theory have a natural extension to the singular grid theory, and are natural under the newly defined singular grid moves. This gives an invariant of singular Legendrian links, and in fact, a broader class of singular links.
A Practical Extension To The Ab/Ba Design, My T.A Nguyen
A Practical Extension To The Ab/Ba Design, My T.A Nguyen
Electronic Theses and Dissertations
In this work, we take a close look at a general extension to the traditional AB/BA
crossover design that is commonly used in clinical trials to determine the effectiveness
of new candidate drugs. While the traditional crossover design requires each patient
in the study to be measured on both treatment A and treatment B, we consider the
possibility of additional measurements being available on each patient. This produces
designs such as the AABB/BBAA design which has been used in previous studies.
A general test statistic will be derived to test for treatment effects as well as its
corresponding power function …
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 …
On A Class Of Critical N-Laplacian Problems, Tsz Chung Ho
On A Class Of Critical N-Laplacian Problems, Tsz Chung Ho
Theses and Dissertations
We establish some existence results for a class of critical N-Laplacian problems in a bounded domain in RN. In the absence of a suitable direct sum decomposition, we use an abstract linking theorem based on the Z2-cohomological index to obtain a nontrivial critical point.
On The P-Inner Functions Of ℓPA, James G. Dragas
On The P-Inner Functions Of ℓPA, James G. Dragas
Mathematics & Statistics Theses & Dissertations
Define ℓpA as the space of all functions holomorphic over the unit disk whose Taylor coefficients are p-summable. Despite their classical origins and simple definition, these spaces are not as well understood as one might expect. This is particularly true when compared with the Hardy spaces, which provide a useful road map for the types of questions we might consider reasonable. In this work we examine the zero sets of ℓpA, p ∈ (1;∞), as well as a notion of inner function that is consistent with the approach taken on numerous other function spaces. …
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 Peer-Reviewed Publications
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. …
