The Early Bronze Age Ceramic Assemblage From Tell Ta'annek, Palestine, Mark S. Ziese

Dissertations

The problem

Greenberg has recently stated that isolating temporal ceramic indicators for the Early Bronze II-III periods is "one of the thorniest issues in the archaeology of Palestine" (2000: 183). Part of theproblem stems from the homogenous nature of ceramic assemblages from Early Bronze Age Palestine; part of it stems from a continued lack of published information. Both of these issues are addressed by this study. Excavations at Tell Ta`annek between 1963 and 1967 unearthed the remains of a multi-period site, including the residues of an Early Bronze II-III fortified settlement. It is purposed here to isolate that portion of …

Dissertations

Problem . In 1 Cor 8:1-10:29a, Paul has been consistently on the side of the brother in 8:11 whose conscience is weak to eat food offered to idols. But, in 10:29b-30, he seems to reverse himself, here suggesting that one should be able to eat anything, regardless of its provenance or the effect such eating may have on others. Or, what should be made of the two questions asked in the text that appear neither fitted to the context nor directly answered by what precedes and follows in the discussion of εἰδωλόθυτα in 8:1-11:17?

Approach . Scholars have employed various …

The Structure And Stability Of Expanding And Converging Near-Stoichiometric Flames, Raymond Addabbo

Dissertations

The stability of expanding and converging premixed flames is investigated theoretically. These configurations are inherently unsteady and represent simple examples of positively (expanding) and negatively (converging) stretched flames. A new model is employed in this study that incorporates both hydrodynamic and diffusional-thermal effects. The model expands earlier works by incorporating variable transport properties, variations in the mixture strength and a more realistic dependence on viscosity.

The expanding flame is shown to remain stable at small radii provided the thermal diffusivity exceeds the mass diffusivity of the deficient reactant. However, once the flame achieves a critical size, a cellular instability appears, …

Arq Protocol For Joint Source And Channel Coding And Its Applications, Bin He

Dissertations

Shannon's separation theorem states that for transmission over noisy channels, approaching channel capacity is possible with the separation of source and channel coding. Practically, the situation is different. Infinite size blocks are needed to achieve this theoretical limit. Also, time-varying channels require a different approach. This leads to many approaches for source and channel coding. This dissertation will address a joint source and channel coding that suits Automatic Repeat Request (ARQ) application and applies it to packet switching networks. Following aspects of the proposed joint source and channel coding approach will be presented:

1. The design of the proposed joint source …

Evolutionary Polymorphic Neural Networks In Chemical Engineering Modeling, Li Gao

Dissertations

Evolutionary Polymorphic Neural Network (EPNN) is a novel approach to modeling chemical, biochemical and physical processes. This approach has its basis in modern artificial intelligence, especially neural networks and evolutionary computing. EPNN can perform networked symbolic regressions for input-output data, while providing information about both the structure and complexity of a process during its own evolution.

In this work three different processes are modeled: 1. A dynamic neutralization process. 2. An aqueous two-phase system. 3. Reduction of a biodegradation model. In all three cases, EPNN shows better or at least equal performances over published data than traditional thermodynamics /transport or …

Saturation Routing For Asynchronous Transfer Mode (Atm) Networks, Jose Luis Ucles

Dissertations

The main objective of this thesis is to show that saturation routing, often in the past considered inefficient, can in fact be a viable approach to use in many important applications and services over an Asynchronous Transfer Mode (ATM) network. For other applications and services, a hybrid approach (one that partially uses saturation routing) is presented. First, the minimum effects of saturation routing are demonstrated by showing that the ratio, defined as f, of routing overhead cells over information cells is small even for large networks. Second, modeling and simulation and M/D/l queuing analysis techniques are used to show that …

Structural, Transport And Magnetic Studies Of Perovskite Bi1-X Cax Mn O3, Hyungje Woo

Dissertations

This dissertation presents an investigation of the fundamental physics of the perovskite system Bi_1-xCa_xMn0₃. This material belongs to a group of simple perovskites called the manganites which are of technological importance for magnetic device applications as read-head sensors.

The Bi_1-xCa_xMnO₃ system is known to exhibit charge ordering (and high sensitivity to magnetic fields) for a much broader range of x than the well-characterized La_1-xCa_xMnO₃ system. However, the properties of Bi_1-xCa_xMnO₃ over the entire doping range are not well understood. …

Detection Of Vapor Phase Mercury Species By Laser Fluorescence Methods, Xiaomei Tong

Dissertations

Elemental and compound mercury are often both volatile and air stable. Several mercury species emissions have been identified in off-gases from industrial processes. The high toxicity of mercury species and the presence of mercury species in municipal waste and coal have prompted a demand for a cost-effective, accurate, and rugged technique for real-time, continuous detection of mercury species vapors. Real-time, continuous emission measurements are important for process control, monitoring, and remediation. At present, there is no commercial continuous emission monitoring (CEM) technique or instrumentation to reliably monitor volatile mercury species emissions from industrial stacks. Conventional measurement methods, such as cold …

Analysis Of Factors Involved In Ratings Of Treatment Acceptability For Trichotillomania, Amy J. Elliott

Dissertations

Based on the literature, trichotillomania (or chronic hair pulling) appears to be responsive to behavioral interventions, with habit reversal as the most promising intervention. Habit reversal has been shown effective with children and adults of varying levels of severity, but some have questioned the generality and acceptability of the procedure. Little is known about the acceptability of interventions for habit disorders. These two research studies were designed to answer questions regarding the acceptability of behavioral and pharmacological interventions for trichotillomania and to expand the conceptual knowledge of treatment acceptability.

Study 1 compared the acceptability of four interventions targeting trichotillomania. The …

Vortex-Defect Interactions In High-Temperature Superconductors, Valentina Tobos

Dissertations

The topics covered in this thesis are related to two objectives: one refers to the search for methods of improving die critical current density of high-temperature superconductors, a subject which remains of continuing interest for its importance in technological applications. The other direction is aimed at clarifying the phase diagram of high-Tc materials.

The interaction between the structural defects and the vortex system plays a significant role in the capability of these materials to carry large electrical transport currents. Through proton irradiation induced defects we follow the evolution of the critical current density, and its enhancement with increasing point-like defects …

Empirical Spectral Analysis Of Random Number Generators, David Zeitler

Dissertations

Computer simulation procedures have become a staple of research and development in many fields, including statistics. The generation of pseudo random number sequences is the core of computer simulation procedures. Validity of research results often depend on the underlying validity of the generator being used.

In this work we develop the machinery for a class of tests of spatial uniformity based on a multi-dimensional Fourier transform of the empirical probability density function. The test can be adapted to specific requirements and has the added advantage that it has computational complexity that is relatively independent of the number of data points …

Effects Of Software Use On The Preparation Of The Individualized Education Programs (Iep’S), Nancy Ann Beukema

Dissertations

Special educators are required to process paperwork mandated by federal regulations for students with special needs. The Individuals with Disabilities Act of 1997 (IDEA ’97, Public Law 105-17) requires the evaluation of students with special needs occur as frequently as their non-disabled peers. An annual review is also mandated for each student’s individualized educational program (IEP), in order to reevaluate the future goals and objectives of the IEPs. A student identified as needing special education services is one who needs specially designed instruction and this instruction must meet the specific individual needs of that student. IDEA ‘97 mandates the need …

The purpose of this correlational study was to quantitatively assess the construct of the school experience, as determined by academic achievement, as measured by GPA, and the level of involvement in school activities, from the perspective of four measures of student self-esteem. Data were collected from 263 students in grades 6, 8, 10, and 12 in a small district in southwestern Canada. The first part of this study explored the relationship between …

The Politicization Of Ethnicity As A Prelude To Ethnopolitical Conflict: Croatia And Serbia In Former Yugoslavia, Agneza Bozic-Roberson

Dissertations

This interdisciplinary research develops a framework or a model for the study of the politicization of ethnicity, a process that transforms peaceful ethnic conflict into violent inter-ethnic conflict. The hypothesis investigated in this study is that the ethnopolitical conflict that led to the break up of former Yugoslavia was the result of deliberate politicization of ethnicity. The model consists o f three variables— ethnic entrepreneurs as actors, and mass media and political rhetoric as their tools for politicization of ethnicity. Ethnic entrepreneurs, with a conscious interest in mobilizing ethnicity, are given this opportunity in transitional societies in which politicized ethnicity …

Fay Weldon's Late Bloomers And Comedy And A Lawyer, A Vet, And A Couple Of Dogs, One Of Them Dead, Susan Rote Siferd

Dissertations

Creative dissertation begins with a critical study of comedy as Weldon employs it in her novels of marriage, infidelity, and divorce. Traditionally, comedy ends in marriage; Weldon's dark comedies end in self-understanding as a necessary prerequisite to growth and possible future relationship. However, Weldon does not celebrate divorce. She recognizes the impact on women's lives of historic period, world events, and their own female nature. An avowed feminist, Weldon yet refuses to blame men for women's problems, but insists that while women struggle against sexism, they often conform to it. If there is no genre designation comparable to "bildungsroman" for …
