Secondary Mathematics Teachers' Disposition Toward Challenge And Its Impact On Teaching Practice, Yirah Mariana Valverde
Secondary Mathematics Teachers' Disposition Toward Challenge And Its Impact On Teaching Practice, Yirah Mariana Valverde
Open Access Theses & Dissertations
This two phase, sequential exploratory study focused on mathematics teachers' disposition toward challenge and its impact in their teaching practice and students' performance. This heavily qualitative study employed a mixed methodology to answer the following guiding research question: how do teachersâ?? disposition towards challenge affect teaching practice and what is the nature of that relationship?
During the initial phase (quantitative), two teachers who were enrolled in a graduate mathematics at a University in the southwestern U.S. were selected for the study (N=5). The goal of the class was to increase the participants' mathematical knowledge for teaching. The purposive selection was …
Twenty-Seven Element Albertian Semifields, Thomas Joel Hughes
Twenty-Seven Element Albertian Semifields, Thomas Joel Hughes
Open Access Theses & Dissertations
In 1958 Abraham Adrian Albert published his findings on the now famous class of semifields known as twisted fields or, as we refer to them in this Thesis, Albertian semifields. Since the publication of his findings, interest in the topic of semifields has grown and, naturally, some progress has been made in the subject, but there is still much to be studied. Moreover, the greater portion of modern efforts have been made to develop a theory of semifields, with less attention paid to more practical considerations. In this Thesis, we will narrow our investigations to a specific subclass of Albert's …
An A Posteriori Error Estimator For The C0 Interior Penalty Approximations Of Fourth Order Elliptic Boundary Value Problem On Quadrilateral Meshes, Mohammad Arifur Rahman
An A Posteriori Error Estimator For The C0 Interior Penalty Approximations Of Fourth Order Elliptic Boundary Value Problem On Quadrilateral Meshes, Mohammad Arifur Rahman
Open Access Theses & Dissertations
Numerical solutions of fourth order elliptic problems with finite element methods has been the topic of research in computational mechanics for over 50 years. Traditional approaches to solve these problems include using C1 conforming finite element methods which demand the C1 continuity of the underlying shape functions, which is computationally very expensive. In this work, we will present the C0 Interior Penalty Galerkin approximation of the fourth order elliptic problems which relies only on continuous i.e., C0 shape functions, which is much cheaper to implement. The spatial discretization is based on quadrilateral meshes and the underlying C0 shape functions are …
Combining Interval And Probabilistic Uncertainty In Engineering Applications, Andrew Martin Pownuk
Combining Interval And Probabilistic Uncertainty In Engineering Applications, Andrew Martin Pownuk
Open Access Theses & Dissertations
In many practical application, we process measurement results and expert estimates. Measurements and expert estimates are never absolutely accurate, their result are slightly different from the actual (unknown) values of the corresponding quantities. It is therefore desirable to analyze how this measurement and estimation inaccuracy affects the results of data processing. There exist numerous methods for estimating the accuracy of the results of data processing under different models of measurement and estimation inaccuracies: probabilistic, interval, and fuzzy. To be useful in engineering applications, these methods should provide accurate estimate for the resulting uncertainty, should not take too much computation time, …
On An Iteration Method For Solving A Class Of Nonlinear Matrix Equations, Mohamed Illafe
On An Iteration Method For Solving A Class Of Nonlinear Matrix Equations, Mohamed Illafe
Open Access Theses & Dissertations
In this thesis, I looked at the most recent extension of the Banach Contraction Principle [1]. Then I show that a concept of Sorgenfrey space may be used to explain this extension as well as Ran and Reurings fixed point theorem.
Complex Gleason Measures And The Nemytsky Operator, Miguel Angel Valles
Complex Gleason Measures And The Nemytsky Operator, Miguel Angel Valles
Open Access Theses & Dissertations
This Thesis is devoted to generalize previous results on Gleason measures
to complex Gleason measures, and to develop a functional calculus
for complex measures in relation to the Nemytsky operator. Furthermore
we present the interpretation of our results in the field of quantum
mechanics, some concrete examples and further extensions of several
theorems.
The New Issues In Classification Problems, Md Mahmudul Hasan
The New Issues In Classification Problems, Md Mahmudul Hasan
Open Access Theses & Dissertations
The data involved with science and engineering getting bigger everyday. To study and organize a big amount of data is difficult without classification. In machine learning, classification is the problem of identifying a given data from a set of categories. There are several classification technique people using to classify a given data. In our work we present a sparse representation technique to perform classification. The popularity of this technique motivates us to use on our collected samples. To find a sparse representation, we used an $l_1$-minimization algorithm which is a convex relaxation algorithm proven very efficient by researchers. The purpose …
