Design and Synthesis of Novel Cage-Functionalized Crown Ethers: A New Class of Ag Complexants.

Description: Three different types of cage crown ethers have been prepared and their complexation properties with Ag(I) have been studied. Atomic absorption, fluorescence quenching, and UV absorption have been used to study the interaction between the hosts (cage crown ethers) and guests (Ag+). For the cage-annulated crown ethers that contain aromatic rings, cation-π and π-π interactions may contribute significantly to the overall complexation ability of the host system. Piperazine groups may cooperate, and… more

A Comparison of IRT and Rasch Procedures in a Mixed-Item Format Test

Description: This study investigated the effects of test length (10, 20 and 30 items), scoring schema (proportion of dichotomous ad polytomous scoring) and item analysis model (IRT and Rasch) on the ability estimates, test information levels and optimization criteria of mixed item format tests. Polytomous item responses to 30 items for 1000 examinees were simulated using the generalized partial-credit model and SAS software. Portions of the data were re-coded dichotomously over 11 structured proportions to … more

Building an Intelligent Filtering System Using Idea Indexing

Description: The widely used vector model maintains its popularity because of its simplicity, fast speed, and the appeal of using spatial proximity for semantic proximity. However, this model faces a disadvantage that is associated with the vagueness from keywords overlapping. Efforts have been made to improve the vector model. The research on improving document representation has been focused on four areas, namely, statistical co-occurrence of related items, forming term phrases, grouping of related words,… more

A Dynamic and Thermodynamic Approach to Complexity.

Description: The problem of establishing the correct approach to complexity is a very hot and crucial issue to which this dissertation gives some contributions. This dissertation considers two main possibilities, one, advocated by Tsallis and co-workers, setting the foundation of complexity on a generalized, non-extensive , form of thermodynamics, and another, proposed by the UNT Center for Nonlinear Science, on complexity as a new condition that, for physical systems, would be equivalent to a state of matt… more

Our enemy, ourselves: Political conspiracy in American cinema, 1970-present.

Description: This thesis is an examination of "paranoid conspiracy" films, a film noir subgenre that emerged in mainstream American cinema in the early 1970s and turns on vast, shadowy conspiracies located within U.S. "power structures" (government agencies, the military, the media) and directed against the American public. Specifically, it focuses on the emergence of these films in the 1970s, their almost complete disappearance during the Reagan presidency, and subsequent reemergence in the early 1990s. P… more

Systematic Composition and Intuition in a Concerto for Organ and Orchestra

Description: Historically, composers have used methods in addition to inspiration in writing music. Regardless of the source materials they used, composers ultimately rely on their musical sensitivity to inform the compositional decision-making. Discuses the rotational aspects of decimals that are created from certain prime-number denominators, and focuses on the prime number 17. Shows how these decimals can be transformed by converting them to different number bases. Looks at the Golden Proportion and its … more

Creativity and Affective Traits Across the Life Span: Developmental Influences Among Adolescents and Older Adults

Description: In recent years, empirical research has consistently supported an association between susceptibility to affective illness and creativity at the level of eminent achievement and at the non-eminent, or "everyday creativity" level. Although this research has provided greater evidence for the existence of this link, it has simultaneously unearthed more questions about how and why such an association exists. The purpose of this research was twofold: first, to provide further analysis of the nature o… more

Bounded Dynamic Source Routing in Mobile Ad Hoc Networks

Description: A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance … more

Godot in Earnest: Beckettian Readings of Wilde

Description: Critics and audiences alike have neglected the idea of Wilde as a precursor to Beckett. But I contend that a closer look at each writer's aesthetic and philosophic tendencies-for instance, their interest in the fluid nature of self, their understanding of identity as a performance, and their belief in language as both a way in and a way out of stagnancy -will connect them in surprising and highly significant ways. This thesis will focus on the ways in which Wilde prefigures Beckett as a dramati… more

Modeling Complex Forest Ecology in a Parallel Computing Infrastructure

Description: Effective stewardship of forest ecosystems make it imperative to measure, monitor, and predict the dynamic changes of forest ecology. Measuring and monitoring provides us a picture of a forest's current state and the necessary data to formulate models for prediction. However, societal and natural events alter the course of a forest's development. A simulation environment that takes into account these events will facilitate forest management. In this thesis, we describe an efficient parallel imp… more

Register Unification in Light of Twentieth-Century Vocal Pedagogy

Description: The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other av… more

Mechanical behavior and performance of injection molded semi-crystalline polymers.

Description: I have used computer simulations to investigate the behavior of polymeric materials at the molecular level. The simulations were performed using the molecular dynamics method with Lennard-Jones potentials defining the interactions between particles in the system. Significant effort was put into the creation of realistic materials on the computer. For this purpose, an algorithm was developed based on the step-wise polymerization process. The resulting computer-generated materials (CGMs) exhibit… more
