Combinatorial Design And Analysis Of Optimal Multiple Bus Systems For Parallel Algorithms., Priyalal D. Kulasinghe Jan 1995

Combinatorial Design And Analysis Of Optimal Multiple Bus Systems For Parallel Algorithms., Priyalal D. Kulasinghe

LSU Historical Dissertations and Theses

This dissertation develops a formal and systematic methodology for designing optimal, synchronous multiple bus systems (MBSs) realizing given (classes of) parallel algorithms. Our approach utilizes graph and group theoretic concepts to develop the necessary model and procedural tools. By partitioning the vertex set of the graphical representation CFG of the algorithm, we extract a set of interconnection functions that represents the interprocessor communication requirement of the algorithm. We prove that the optimal partitioning problem is NP-Hard. However, we show how to obtain polynomial time solutions by exploiting certain regularities present in many well-behaved parallel algorithms. The extracted set of interconnection …

An Approach To The Musical Analysis Of Wind Band Literature Based On Analytical Modes Used By Wind Band Specialists And Music Theorists., Jerome Raymond Markoch Jr Jan 1995

An Approach To The Musical Analysis Of Wind Band Literature Based On Analytical Modes Used By Wind Band Specialists And Music Theorists., Jerome Raymond Markoch Jr

LSU Historical Dissertations and Theses

The purpose of this study was to construct a method of musical analysis based on analytical modes used by theorists and wind-band specialists, and to apply this method to wind-band literature. The study was motivated by the failure of wind-band sources to address the spectrum of musical analysis and ideas practiced in the music theory community. Two bodies of literature were reviewed: (1) wind-band analyses and methods of analysis proposed by conductors and composers, and (2) analytical methodologies described by theorists. The analytical method advocated in this study modified and incorporated methods and ideas espoused by two theorists (Jan LaRue, …

An Examination Of Costs And Per-Pupil Revenues In Special Education With Simulations Designed To Enhance The Equity Of Louisiana's Special Education Financing Program., Alton John Royer Jr Jan 1995

An Examination Of Costs And Per-Pupil Revenues In Special Education With Simulations Designed To Enhance The Equity Of Louisiana's Special Education Financing Program., Alton John Royer Jr

LSU Historical Dissertations and Theses

The primary issues this study addressed were special education costs and equity of special education per-pupil revenues among Louisiana's sixty-six school districts. Actual data from 1980 to 1992 were examined and four special education finance models were developed which addressed these issues. Average annual rates of increase in mean per-pupil revenues for regular education and special education were examined to determine the increase in cost of special education versus regular education. Findings indicated special education per-pupil revenues increased at four times the rate of regular education per-pupil revenues for the period examined. Special education per-pupil revenues were examined to determine …

Model For Planning Well Control Operations Involving An Induced Fracture., Alvaro Felippe Negrao Jan 1995

Model For Planning Well Control Operations Involving An Induced Fracture., Alvaro Felippe Negrao

LSU Historical Dissertations and Theses

This dissertation presents a numerical simulator for designing a dynamic kill of an underground blowout. The simulator consists of three sub-programs: a reservoir model, a wellbore model, and a fracture model. Previously published procedures have modeled the fracture by assuming a constant pressure in the wellbore at the depth of fracture. This assumption has sometimes led to unrealistic results. In this work, a hydraulic fracture model is coupled with the reservoir and wellbore model using a system analysis approach. The hydraulic fracture model is based on a pseudo-3D model with some modifications introduced to more accurately model the extension of …

A Cross-Case Analysis Of Middle School Reading Teachers' Theoretical Orientations As They Relate To Classroom Practices., Shirley Theriot Fogleman Jan 1995

A Cross-Case Analysis Of Middle School Reading Teachers' Theoretical Orientations As They Relate To Classroom Practices., Shirley Theriot Fogleman

LSU Historical Dissertations and Theses

Each interaction between teachers and students is a reflection of the theory that these professionals, sometimes unknowingly, posit about what should be occurring in their classrooms. The purpose of this study is to explore the differences between middle school language arts teachers' beliefs about how children actually read a text, and how these teachers translate these beliefs into classroom practices. The beliefs we hold about reading comprehension are essential to our understanding about how we should instruct and assess our students in our classes. Leu and Kinzer (1988) refer to two beliefs' frameworks of comprehension in reading, based on the …

Parallelization Of Reconstructability Analysis Algorithms., Patti E. Iles Jan 1995

Parallelization Of Reconstructability Analysis Algorithms., Patti E. Iles

LSU Historical Dissertations and Theses

Bush Jones published a series of papers providing sequential algorithms that are key to reconstructability analysis. These algorithms include the determination of unbiased reconstructions and a greedy algorithm for a generalization of the reconstruction problem. The implementation of these sequential algorithms provide scientists and mathematicians with the means of utilizing reconstructability analysis in systems modeling. The algorithms, however, are so computationally intensive that the system is limited to a very small set of variables. Many papers have been written applying reconstructability analysis and maximum entropy methods to various disciplines. Reconstructability analysis has the potential of dramatically impacting the scientific community, …

Linguistic And Cultural Immersion And Second Language Acquisition: International Young Student Exchange., Rosita Mira Maristany Jan 1995

Linguistic And Cultural Immersion And Second Language Acquisition: International Young Student Exchange., Rosita Mira Maristany

LSU Historical Dissertations and Theses

The trend in foreign language learning reflects a move from "fragmented" language to "whole" language (Rigg 1991). It includes the individual as well as the social aspect of language acquisition; and the integration of language and culture. Student international exchange programs provide the ideal atmosphere for "whole" language learning and the integration of language and culture in total language and cultural immersion. Most research in international student exchange programs described the organization of the program or addressed a particular variable. There is a need for integrative "whole" research rather than "fragmented" research. The method chosen as most appropriate for this …

The Habitat, Ecology And Epidemiology Of Eastern Equine Encephalomyelitis In Southeast Louisiana., Kenny L. Samui Jan 1995

The Habitat, Ecology And Epidemiology Of Eastern Equine Encephalomyelitis In Southeast Louisiana., Kenny L. Samui

LSU Historical Dissertations and Theses

Many unanswered questions on the epidemiology and ecology of eastern equine encephalomyelitis (EEE) still preclude a complete understanding of its natural history. Among these are the distribution and epidemic vectors of EEE virus (EEEV) in different regions, habitats, and foci; its inter-epidemic maintenance, and overwintering mechanisms. Phase 1 of a research project designed to find answers to the above questions with regard to southeast Louisiana was conducted over 1992 and 1993, and consisted of several individual studies. These included 3 mosquito studies to determine major horse- and bird-feeding mosquito species that could be the EEEV epidemic vectors in southeast Louisiana; …

A Formal Methodology For Deriving Purely Functional Programs From Z Specifications Via The Intermediate Specification Language Funz., Linda Bostwick Sherrell Jan 1995

A Formal Methodology For Deriving Purely Functional Programs From Z Specifications Via The Intermediate Specification Language Funz., Linda Bostwick Sherrell

LSU Historical Dissertations and Theses

In recent years, both formal methods and software reuse have been increasingly advocated as a means of alleviating the ills of the software crisis. During this same time period, purely functional programming languages, which have a long history in the realm of rapid prototyping, have emerged as a viable medium for real-world applications. Since these trends are likely to continue, this work describes a methodology that facilitates the derivation of purely functional programs from existing Z specifications. A unique aspect of the methodology is its incorporation of an intermediate specification language (FunZ) during the design phase of software development. Most …

Parallel Algorithms For Constructing Convex Hulls., Jigang Liu Jan 1995

Parallel Algorithms For Constructing Convex Hulls., Jigang Liu

LSU Historical Dissertations and Theses

For a given set of planar points S, the convex hull of S, CH(S), is defined to be a list of ordered points which represents the smallest convex polygon that contains all of the points. The convex hull problem, one of the most important problems in computational geometry, has many applications in areas such as computer graphics, simulation and pattern recognition. There are two strategies used in designing parallel convex hull algorithms. One strategy is the divide-and-conquer paradigm. The disadvantage to this strategy is that the recursive merge step is complicated and difficult to implement on current parallel machines. The …

Interaural Discrimination And Localization Of Cross-Frequency Stimuli In Normal-Hearing And Impaired-Hearing Listeners., Laura K. Smith

LSU Historical Dissertations and Theses

The ability to discriminate interaural differences in complex signal and to localize those signals was examined in listeners with normal hearing (NH) and with bilateral high frequency sensorineural hearing impairment (IH). Just noticeable differences for interaural time and intensity were obtained using 1/3-octave narrow band noise (NBN) stimuli centered at 500 and 4000 Hz in three conditions: (1) the NBNs played in isolation; (2) the NBNs played simultaneously with congruent interaural information across frequency; and (3) the NBNs played simultaneously with either the 500 Hz band dichotic and the 4000 Hz band diotic (a) or the 500 Hz band diotic …

Performing The Community, Telling The Self: Storytelling By Members Of A Group Home For Men With Mental Retardation., Sharon Elizabeth Croft Jan 1995

Performing The Community, Telling The Self: Storytelling By Members Of A Group Home For Men With Mental Retardation., Sharon Elizabeth Croft

LSU Historical Dissertations and Theses

This study uses an ethnographic approach to examine the stories told by members of a group home for men with mental retardation. The author contends that the culture of the group home works to constrain how group home members interact within this community. The author argues, however, that despite the cultural constraints, the men use storytelling to establish their individuality, even though the stories themselves, in their content and in the performance of their telling, often reify cultural constraints and their cultural constructions. The author recounts how she, as ethnographer, interacted within this community. After identifying, describing, and analyzing eight …

Boal And Theatre Of The Oppressed: A Performance-Centered Inquiry Of Eating And Body Image., Leigh Anne Howard Jan 1995

Boal And Theatre Of The Oppressed: A Performance-Centered Inquiry Of Eating And Body Image., Leigh Anne Howard

LSU Historical Dissertations and Theses

Building upon the scholarly tradition that performance is a valuable pedagogical tool, I documented how six performers developed personal awareness, critical consciousness, and the ability to take action as a result of participating in a performance process. I designed a three-stage performance process. During the first phase of the process, focus group discussions, participants exhibited little awareness of their specific eating habits or the cultural constructedness of those habits. As they completed the first phase, they became more aware of their behaviors, and they began to identify food's social function. At the second stage, rehearsal sessions, six performers began to …

Press Framing Of Presidential Crisis Rhetoric In A Post-Cold War World: The Haitian Crisis In 1993., Jim Andrew Kuypers Jan 1995

Press Framing Of Presidential Crisis Rhetoric In A Post-Cold War World: The Haitian Crisis In 1993., Jim Andrew Kuypers

LSU Historical Dissertations and Theses

This study employs a historical/critical approach to analyze the response of the Clinton Administration to the Haiti situation during 1993. The relationship between contemporary presidential crisis communication and the agenda-setting and agenda-extension functions of the press is especially considered. Specifically, this study employs a frame analysis which compares the frame generated by the Clinton Administration with that used by the press, represented by New York Times and the Washington Post. The importance of this study lies in its timeliness; President Clinton is the first atomic-age President not to have the Cold War meta-narrative to use in legitimating international crises. Prior …

Behavioral And Chemical Ecology Of Formosan Subterranean Termites, Coptotermes Formosanus Shiraki., Jian Chen Jan 1995

Behavioral And Chemical Ecology Of Formosan Subterranean Termites, Coptotermes Formosanus Shiraki., Jian Chen

LSU Historical Dissertations and Theses

Three colonies of Formosan subterranean termites collected from Lake Charles, Louisiana were not antagonistic towards each other, and three of five colonies collected from New Orleans, Louisiana also showed no aggression. Colonies collected from widely separated parishes, however, often showed antagonistic behavior towards each other. Workers provided food to soldiers from different but amicable colonies whether nestmate soldiers were present or not. Intercolonial mutual grooming also was observed. Furthermore, termites assisted other termites of the same colony or an amicable one in finding food. This assistance in finding food occurred when termites foraged underground or on the surface. Based on …

Effects Of Salt Dome Dissolution On Sediment Diagenesis: An Experimental And Field Study., William Lee Esch Jan 1995

Effects Of Salt Dome Dissolution On Sediment Diagenesis: An Experimental And Field Study., William Lee Esch

LSU Historical Dissertations and Theses

The introduction of high-salinity or high-ionic strength fluids into sedimentary formations has been hypothesized to induce diagenetic reactions. Such reactions are potentially important because they alter porosity and affect the migration of fluids such as petroleum, or hazardous liquid wastes disposed of by deep-well injection. An experimental and field investigation of the controls on diagenesis in high and variable salinity environments was undertaken regarding Gulf Coast salt domes because ambient formation waters and sediments around salt domes are influenced by the dissolution of evaporites. Laboratory experiments were performed with carbonate-free and carbonate-bearing siliciclastic sediments in aqueous NaCl solutions with concentrations …

Effects Of Exogenous Female Sex Hormones On Food Intake, Macronutrients And Body Weight In The Ovariectomized Postbreeder Female Rat., Jan Barton Hamilton

LSU Historical Dissertations and Theses

Hormone replacement therapy (HRT) is chosen by a growing segment of the postmenopausal population. Mid-life body weight gain is perceived to increase further with exogenous HRT. To examine hormonal effects on caloric intake (CI), carbohydrate (CHO), FAT, protein (PRO), chocolate and body weight (BW) in a female model, Sprague-Dawley postbreeder (n = 55) rats (10 mos., 10 litters of pups) were ovariectomized (OV) and implanted with 17 $\beta$ estradiol (E) and/or progesterone (P), or placebo in three separate studies (phases) of 10 days each. Uterine weights (p =.0001) and radioimmunoassay confirmed hormonal bioactivity. The sham (S) group with placebo implant …

John Guare: In Search Of America., Kenny Clifford Gannon Jan 1995

John Guare: In Search Of America., Kenny Clifford Gannon

LSU Historical Dissertations and Theses

This study examines the full scope of Guare's plays, from his Off-Off Broadway experimentation in the sixties through his 1992 play Four Baboons Adoring the Sun, and their place in America's cultural landscape. Set against the framework of modern cultural history, the investigation attempts to reveal Guare's vision of modern America's quest for fulfillment through the correlation of textual and stylistic analysis, critical response, and Guare's stated views. The study contends that Guare's portrayal of American desire unmasks the mass media's contamination of the American dream. From the very inception of his dramatic imagination, Guare has mixed fantasy and reality …

Dietary Chromium Supplementation For Pigs And Chickens., Terry Lynn Ward Jan 1995

Dietary Chromium Supplementation For Pigs And Chickens., Terry Lynn Ward

LSU Historical Dissertations and Theses

Three experiments were conducted with pigs and four experiments were conducted with chickens to determine the effects of supplemental dietary Cr on growth performance, carcass characteristics, tissue minerals and plasma metabolite and hormone concentrations. In pigs (Exp. 1) 200 ppb Cr from seven different sources tended to decrease performance during the grower phase and increase growth performance during the finisher phase. Dietary Cr had minimal effects on plasma metabolite and hormone concentrations and Cr did not affect carcass characteristics. In general, dietary Cr increased tissue Cr concentration, except for longissimus muscle (LM). In Exp. 2, pigs were fed 400 ppb …

Inhibition Of Mixing In Chaotic Quantum Dynamics, B. S. Helmkamp, D. A. Browne Jan 1995

Inhibition Of Mixing In Chaotic Quantum Dynamics, B. S. Helmkamp, D. A. Browne

Faculty Publications

We study the quantum chaotic dynamics of an initially well-localized wave packet in a cosine potential perturbed by an external time-dependent force. For our choice of initial condition and with Latin small letter h with stroke small but finite, we find that the wvae packet behaves classically (meaning that the quantum behavior is indistinguishable from that of the analogous classical system) as long as the motion is confined to the interior of the remnant separatrix of the cosine potential. Once the classical motion becomes unbounded, however, we find that quantum interference effects dominate. This interference leads to a long-lived accumulation …
