Problems of Attendance in the Elementary School
… problem. Therefore, the purpose of this study is three-fold: 1. To explore certain problems of pupil attendance on the elementary school level. 2. To identify and study problems which directly affect school attendance adversely. 3. To discover possible administrative policies which might …

The Algebra of Systems Biology
… shows how tools from mathematics are suitable to study problems in systems biology such as modeling, dynamics prediction, reverse engineering and many others. The advantage of using mathematical tools is that there is a large number of theory, algorithms and software available. This work focuses …

Topics in geometric analysis with applications to partial differential equations
… the mathematical tools and methods used to study problems which bridge between analysis and geometry. Such an undertaking is particularly useful in situations in which the geometry is variable, such as: -- the theory of minimal surfaces, in differential geometry -- shape analysis and …

Extremal problems on edge-colorings, independent sets, and cycle spectra of graphs
We study problems in extremal graph theory with respect to edge-colorings, independent sets, and cycle spectra. In Chapters 2 and 3, we present results in Ramsey theory, where we seek Ramsey host graphs with small maximum degree. In Chapter 4, we study a Ramsey-type problem on edge-labeled trees, …

Spaces of Compact Operators
In this dissertation we study the structure of spaces of operators, especially the space of all compact operators between two Banach spaces X and Y. Work by Kalton, Emmanuele, Bator and Lewis on the space of compact and weakly compact operators motivates much of this paper. Let L(X,Y) be the Banach …

An Investigative Study of Gurney Flaps on a NACA 0036 Airfoil
… computational fluid dynamics (CFD). During the study, problems with the wind tunnel data were seen. After a careful diagnosis, the problem was traced to dirty flow conditioners which were subsequently replaced. </p> <p>Five Gurney flaps at 1, 2, 3, 4, and 5% of the chord were tested. The Gurney …

Problems Encountered in Money Laundering Investigations
The purpose of this study is to identify how the U.S. is responding to money laundering and what kind of problems arise while countering it, beginning with a detailed description of money laundering, its stages, typologies, impacts, and complications. Due to the broad nature of this subject only …

Methods of single-molecule energy landscape reconstruction with optical traps
… DNA hairpin and then apply these methods to study problems of practical biophysical interest. CCR5 mRNA has been demonstrated to stimulate -1 programmed ribosomal frameshifting and we measure its structural properties. We measure the binding energy of a GA/AG tandem mismatch, one of many …

Forbidden substructures: induced subgraphs, Ramsey games, and sparse hypergraphs
We study problems in extremal combinatorics with respect to forbidden induced subgraphs, forbidden colored subgraphs, and forbidden subgraphs. In Chapter 2, we determine exactly which graphs H have the property that almost every H-free graph has a vertex partition into k cliques and independent …

Essays in financial engineering
… that apply techniques of operations research to problems in financial engineering. In particular, we study problems in portfolio optimization and options pricing. The first essay is motivated by the fact that derivative securities are equivalent to specific dynamic trading strategies in complete …

Dematerialisation of a photographic collection at the concrete institute’s information centre
… photographic collections comes with its unique problems. The purpose of this study is to improve the state of the photographic collection by organising it for easy retrieval, allocating metadata and preserving it for future use. This study employed the action research method to study problems of …

The social construction of suicide in Libyan society
The aim of this study is to explore how the suicide act is constructed and evaluated in Libyansociety. The methodology includes an analysis of 172 prosecutors' files covering the periodfrom 2000 to 2009 which exist in the sub-public prosecution departments. These concerncases of those who succeeded …

Coherence and synchronization of noisy-driven oscillators
In the present dissertation paper we study problems related to synchronization phenomena in the presence of noise which unavoidably appears in real systems. One part of the work is aimed at investigation of utilizing delayed feedback to control properties of diverse chaotic dynamic and stochastic …

Cluster Dynamical Mean-Field Theory: Applications to High-Tc Cuprates and to Quantum Chemistry
… developed dynamical mean-field approximation to study problems in strongly correlated electron systems, including high-Tc cuprate superconductors as well as a few quantum chemical reference systems. We start with an introduction to the background of the interacting electron systems, followed by a …

Generalized Satisfiability Problems
… of complexity theory is the classification of problems with respect to their consumption of resources (e.g., running time or required memory). To study the computational complexity (i.e., consumption of resources) of problems, similar problems are grouped into so called complexity classes. …

Computational analyses of immune responses at disparate temporal and spatial scales
… from many outside fields. Our approach to studying the immune system computationally has been pragmatic: we have applied any analysis method necessary to understand questions motivated by experimental biology, rather than use biology specifically to discover new physics or methods. Our …

Virtual museum projects for culturally responsive teaching in American Indian education
This study consists of four case studies of virtual museum projects conducted in partnerships between tribally controlled American Indian schools and museums with Native American collections. The purpose of the study was two-fold: to examine virtual museum projects as an educational innovation, and …
