On The Characterization Of Finite Dimensional Hida Distributions., Kyoung Sim Lee Jan 1993

On The Characterization Of Finite Dimensional Hida Distributions., Kyoung Sim Lee

LSU Historical Dissertations and Theses

The mathematical framework of white noise analysis is based on an infinite dimensional analogue of the Schwartz distribution theory. The Lebesgue measure on $\IR\sp{k}$ is replaced with standard Gaussian measures $\mu$ on infinite dimensional spaces. There is an infinite dimensional analogue $({\cal E})\subset L\sp2({\cal E}\sp*,\mu)\subset({\cal E})\sp*$ of a Gel'fand triple ${\cal E}\subset E\subset{\cal E}\sp*$ which is obtained from ${\cal S}(\IR\sp{k})\subset L\sp2(\IR\sp{k})\subset{\cal S}\sp*(\IR\sp{k})$ in a general setup. There are spaces $({\cal E}\sp\beta),({\cal E}\sp\beta)\sp*, \beta\in\lbrack 0,1)$ with $({\cal E}\sp\beta)\subset({\cal E})\subset L\sp2({\cal E}\sp*,\mu)\subset({\cal E})\sp*\subset({\cal E}\sp\beta)\sp*.$. The compositions of Schwartz distributions and Gaussian random variables have been discussed. A new Gel'fand triple ${\cal H}(\IR\sp{k})\subset{\cal …

Linkage By Generically Gorenstein Cohen-Macaulay Ideals., Heath Mayall Martin Jan 1993

Linkage By Generically Gorenstein Cohen-Macaulay Ideals., Heath Mayall Martin

LSU Historical Dissertations and Theses

In a Gorenstein local ring R, two ideals A and B are said to be linked by an ideal I if the two relations A = (I: B) and B = (I: A) hold. In the case that I is a complete intersection, or a Gorenstein ideal, it is known that linkage preserves the Cohen-Macaulay property. That is, if A is a Cohen-Macaulay ideal, then so is B. However, if I is allowed to be a generically Gorenstein, Cohen-Macaulay ideal, easy examples show that this type of linkage does not preserve the Cohen-Macaulay property. The primary purpose of this work …

The Influence Of Teacher Behavior On The Distribution Of Achievement In The Classroom: An Application Of The Hierarchical Linear Model., Leslie Sanford Arceneaux Jan 1993

The Influence Of Teacher Behavior On The Distribution Of Achievement In The Classroom: An Application Of The Hierarchical Linear Model., Leslie Sanford Arceneaux

LSU Historical Dissertations and Theses

The purpose of the study was to investigate the effects of classroom practices on the distribution of achievement within the classroom as well as on mean levels of achievement through the use of the Hierarchical Linear Model (Raudenbush & Bryk, 1986). The investigation focused on sixty classrooms--thirty from schools labeled as effective and thirty from schools labeled as ineffective. Data on teacher behaviors were gathered through classroom observations during which six dimensions of effective teaching were evaluated. These behaviors were interactive time-on-task, classroom management, strategies for monitoring student progress and providing opportunities to learn, strategies for presentation of content and …

The Congruence Extension Property And Related Topics In Semigroups., Jill Ann Dumesnil Jan 1993

The Congruence Extension Property And Related Topics In Semigroups., Jill Ann Dumesnil

LSU Historical Dissertations and Theses

A semigroup has the congruence extension property (CEP) provided that each congruence on each subsemigroup can be extended to a congruence on the semi-group. This property, the ideal extension property (IEP), and other related concepts are studied from both an algebraic and a topological perspective in this work. A characterization of semigroups with CEP is given in terms of the lattice of congruences. A similar result is obtained for IEP. Semigroups in which the relation "is an ideal of" is transitive (t-semigroups) are explored. It is shown that each of CEP and IEP implies this condition and that these are …

Transcription Initiation Studies With Bacillus Subtilis Promoters Containing Curved Dna., Douglas James Stemke Jan 1993

Transcription Initiation Studies With Bacillus Subtilis Promoters Containing Curved Dna., Douglas James Stemke

LSU Historical Dissertations and Theses

Many promoters contain a curved DNA component essential for high levels of transcription activity. The present work approached the study of these unusual DNA structures in a twofold manner. First, promoter binding by RNA polymerase from Bacillus subtilis and Escherichia coli was examined using a collection of promoters containing DNA curvature. Promoter binding by both RNA polymerases was governed primarily by the nucleotide sequence at the highly conserved $-$10 and $-$35 regions of the promoters. However, the presence of curved DNA, immediately upstream of the $-$35 region of the promoter, predictably increased binding to those promoters which contained curved DNA …

African American Students' Perception Of Mandatory Participation In A Remedial Program At An Historically Black University In The South., Deborah Burson Smith Jan 1993

African American Students' Perception Of Mandatory Participation In A Remedial Program At An Historically Black University In The South., Deborah Burson Smith

LSU Historical Dissertations and Theses

Academically underprepared college bound students and remedial instruction at the collegiate level continue to be serious and recurring problems for postsecondary institutions throughout the United States. Although many institutions have attempted to address the academic needs of underprepared students by providing mandatory programs with varied approaches in reading, writing, and mathematics, educators, theorists, and scholars have given little attention to the effects of mandatory participation on students' perceptions of a remedial program or classroom. This research is designed to provide an inside view of the remedial classroom and underprepared African American students' interpretations of certain practices that may impact their …

A Monte Carlo Method In Contribution Response Transport., Charles Habib Aboughantous Jan 1993

A Monte Carlo Method In Contribution Response Transport., Charles Habib Aboughantous

LSU Historical Dissertations and Theses

A contribution response Monte Carlo method is developed and successfully applied to a sample deep penetration shielding problem. The random walk is simulated in most of its parts like in conventional M.C. by introducing the concept of a fictitious response particle. The scoring is peculiar to the proposed method and it need not be made at the detector itself so that computing time can be reduced by an order of magnitude or more depending on the geometry of the problem. The probability density functions are natural. They possess properties not encountered in conventional M.C. methods currently in use. The selection …

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander Jan 1993

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander

LSU Historical Dissertations and Theses

"The Poetry In-Between: Presence and Absence in Whitman, Rimbaud, and Hopkins" analyzes three major nineteenth-century poets and their development of a poetics which has as its chief focus of concern the issue of presencing an eternal and universal "Other" by which to assess self identity. After the Kantian critique and the seeming reduction of human knowledge to phenomenal perceptions, early nineteenth-century poets and theorists feared the entrapment and isolation of the self in subjective awareness. The romantics, such as Friedrich Schlegel, sought ways to overcome such alienating subjectivity and ultimately conceived of the poet as a privileged spokesman and arbiter …

Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu Jan 1993

Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu

LSU Historical Dissertations and Theses

This dissertation describes extensions of post-structuralism in contemporary curriculum discourses. Post-structuralist thought is mainly associated with the seminal work of Michel Foucault, Jacques Derrida, Gilles Deleuze, Jean-Francois Lyotard, and Michel Serres. Post-structural criticism and analysis challenge prevailing structuralist approaches and question the fundamental assumptions upon which these approaches rest. A key assumption of structural approaches is that all phenomena are constituted by an underlying structure. In curriculum, these structural assumptions (often scientific) remain unacknowledged and thus are immunized against criticism; rather, they are incorporated into the preferred structural analyses, interpretations, and organizations promoted by the promise of order and rationality. …

Optical Character Recognition Using Morphological Attributes., Gili Mendel Jan 1993

Optical Character Recognition Using Morphological Attributes., Gili Mendel

LSU Historical Dissertations and Theses

This dissertation addresses a fundamental computational strategy in image processing hand written English characters using traditional parallel computers. Image acquisition and processing is becoming a thriving industry because of the frequent availability of fax machines, video digitizers, flat-bed scanners, hand scanners, color scanners, and other image input devices that are now accessible to everyone. Optical Character Recognition (OCR) research increased as the technology for a robust OCR system became realistic. There is no commercial effective recognition system that is able to translate raw digital images of hand written text into pure ASCII. The reason is that a digital image comprises …

Reliability Analysis Of The Hypercube Architecture., Sieteng Soh Jan 1993

Reliability Analysis Of The Hypercube Architecture., Sieteng Soh

LSU Historical Dissertations and Theses

This dissertation presents improved techniques for analyzing network-connected (NCF), 2-connected (2CF), task-based (TBF), and subcube (SF) functionality measures in a hypercube multiprocessor with faulty processing elements (PE) and/or communication elements (CE). These measures help study system-level fault tolerance issues and relate to various application modes in the hypercube. Solutions discussed in the text fall into probabilistic and deterministic models. The probabilistic measure assumes a stochastic graph of the hypercube where PE's and/or CE's may fail with certain probabilities, while the deterministic model considers that some system components are already failed and aims to determine the system functionality. For probabilistic model, …

Genetic Algorithms And The Satisfiability Of Large-Scale Boolean Expressions., Thomas A. Bitterman Jan 1993

Genetic Algorithms And The Satisfiability Of Large-Scale Boolean Expressions., Thomas A. Bitterman

LSU Historical Dissertations and Theses

The two new genetic methods overpopulation and bitwise expected value are introduced. In overpopulation a temporary population of size Mn (M $>$ 1) is created using genetic operators and the n children with the highest estimated fitness values are selected as the next generation. The rest are discarded. Bitwise expected value (bev) is the fitness estimation function used. Overpopulation and bitwise expected value are applied to the NP-complete problem 3SAT (a special form of Satisfiability in which the boolean expression consists of the conjunction of an arbitrary number of clauses where each clause consists of the disjunction of 3 …

Strongylus Vulgaris: Protection, Pathology And Humoral Immune Responses In The Immunized Pony., Clifton Michael Monahan Jan 1993

Strongylus Vulgaris: Protection, Pathology And Humoral Immune Responses In The Immunized Pony., Clifton Michael Monahan

LSU Historical Dissertations and Theses

Protective resistance to Strongylus vulgaris infection was examined by immunization of ponies with radiation-attenuated larvae or soluble parasite homogenates. Twelve yearling ponies raised and maintained under parasite-free conditions were divided into four groups which received either radiation-attenuated L$\sb3$; aqueous-soluble adult somatic antigens plus adjuvant; aqueous-soluble larval somatic antigens with excretory/secretory products and adjuvant; or media with adjuvant. Ponies were immunized twice; radiation-attenuated L$\sb3$ were administered orally and soluble antigens or control injections were given intramuscularly. Six weeks following the second immunization, ponies were challenged per os with virulent S. vulgaris L$\sb3.$ Ponies were monitored twice daily for rectal temperatures and …

Reconstructability Theory For General Systems And Its Application To Automated Rule Learning., Sudhir Kumar Trivedi Jan 1993

Reconstructability Theory For General Systems And Its Application To Automated Rule Learning., Sudhir Kumar Trivedi

LSU Historical Dissertations and Theses

The two problems in reconstructability analysis, abbreviated as RA, are referred to as the reconstructability problem and the identification problem. The former relates to the process of reconstructing a given system under a given criterion from the knowledge of its subsystems and, during this process, identifying those subsystems that are important in the reconstruction. The latter allows the identification of an unknown system from the knowledge of its subsystems. The advent of RA has intensified the research efforts on system studies. The objective of this research is to study the process of system reconstruction for general systems and apply it …

"Sequenza Vii" By Luciano Berio: Background, Analysis And Performance Suggestions., Carrie Marie Vecchione Jan 1993

"Sequenza Vii" By Luciano Berio: Background, Analysis And Performance Suggestions., Carrie Marie Vecchione

LSU Historical Dissertations and Theses

Sequenza VII by Luciano Berio is regarded as one of the major twentieth-century pieces for the oboe. Its unique sounds and logic make it both fascinating and complex. Great demands are put on the performer, who must produce difficult, unconventional sounds. The listener is likewise challenged to accept this new language. An initial hearing can leave a listener excited though baffled, as a first look at the score can cause trepidation even in a fearless performer. The purpose of this paper is to find some order to this compelling piece. This comprehensive study is undertaken from three different perspectives, each …

Dynamic Behavior Of Headspace Gases In Modified Atmosphere Packaging For Meat., Yanyun Zhao Jan 1993

Dynamic Behavior Of Headspace Gases In Modified Atmosphere Packaging For Meat., Yanyun Zhao

LSU Historical Dissertations and Theses

Headspace gas composition in food packaging undergoes dynamic changes as a result of film permeability, postmortem metabolic activity, CO$\sb2$ absorption in water and lipid, and bacteria growth and respiration. A methodology to study dynamic behavior of headspace CO$\sb2$ was developed and used to identify the significant factors influencing CO$\sb2$ behavior within modified atmosphere packaging (MAP) systems for beef. Additionally, a mathematical structure suitable for modeling microbial growth in MAP systems was presented. A combined analytical and experimental method was developed to investigate headspace CO$\sb2$ changes during isothermal storage. The ideal gas law was used as a theoretical basis, and a …

A Multiple Objective Formulation And Algorithm For The Layout Design Of Food Processing Facilities., Francisco A. Escobar Jan 1993

A Multiple Objective Formulation And Algorithm For The Layout Design Of Food Processing Facilities., Francisco A. Escobar

LSU Historical Dissertations and Theses

A multiple objective formulation, which incorporates robustness and constraint enforcement as design criteria, is utilized to model the layout of food processing facilities. These facilities are subject to the compliance with guidelines dictated by public health agencies, changes in product mix, and variation in production levels due to seasonality, which render existing layout design algorithms unsuitable for their design. The solution of the robust multiple objective formulation is implemented using a construction heuristic algorithm, MORCH, and an improvement heuristics, MOLAD. The MORCH/MOLAD hybrid algorithm performs comparably to well known heuristic algorithms where materials handling cost is used as the only …

The Prediction Of Financial Turnaround Of Financially Distressed Firms., Leslie B. Fletcher Jan 1993

The Prediction Of Financial Turnaround Of Financially Distressed Firms., Leslie B. Fletcher

LSU Historical Dissertations and Theses

There is little extant accounting research on the turnaround phenomenon, when a financially distressed firm regains its financial health rather than merging with another firm or filing for protection under the Bankruptcy Act. The goal of this research was to determine whether financial and other publicly available information could be used to predict whether or not a distressed firm would turn around. To achieve that goal, a sample of distressed firms was identified based on their initial rather than final financial condition. A measure external to the firm--Standard and Poor's earnings and dividend ranking for common stock--was used to identify …

Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles Jan 1993

Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles

LSU Historical Dissertations and Theses

The purpose of this study was to explore the use of concept circle diagrams, a newly developed metacognitive strategy (Wandersee, 1987), for meaningful science learning. Two research questions were: (a) Do concept circle diagrams enhance the identification and learning of science concepts more than traditional learning methods? and (b) Do concept circle diagrams evolve in quality within and across three sequences of direct explanation, guided practice, and independent practice? This study builds upon earlier research on two important metacognitive strategies, Vee diagrams (Gowin, 1981) and concept mapping (Novak & Gowin, 1984), used in science education. Participants were members of two …

Squared Law Algorithms: Theory And Applications., Poornachandra Bellamkonda Rao Jan 1993

Squared Law Algorithms: Theory And Applications., Poornachandra Bellamkonda Rao

LSU Historical Dissertations and Theses

This dissertation focuses on a new approach for a hardware implementation of the cyclic convolution operation. The cyclic convolution operation is the core of several functions used in applications related to digital signal processing and error control. Since the operation is multiplication intensive and the cost of a multiplication operation is very high, most of the present research effort attempts to reduce the number of multiplications. Our approach, however, aims at obtaining an efficient implementation by relying on the properties of the special case of multiplication, namely, the squaring operation. Due to the properties exhibited by the squaring operation the …

Three-Dimensional Large-Scale Coherent Structures In A Developing Plane Mixing Layer., Taewon Seo Jan 1993

Three-Dimensional Large-Scale Coherent Structures In A Developing Plane Mixing Layer., Taewon Seo

LSU Historical Dissertations and Theses

A theoretical investigation of the role of three-dimensional large-scale structures and their mutual interactions in a developing, plane mixing layer subjected to external forcing is presented. Large-scale structures are decomposed into 3 fundamental and 2 subharmonic wave modes. Two fundamentals and one subharmonic are three-dimensional. Linear stability of the three-dimensional, viscous shear layer is formulated and solved as the basis for the solution of a nonlinear formulation based on an energy method. This method leads to a set of nonlinearly-coupled, ordinary differential equations governing the evolution of modal energies and phases, and of the shear layer thickness. A parametric study …

A Study Of Heat Transfer In Rotary Desorbers Used To Remediate Contaminated Soils., Charles Alan Cook Jan 1993

A Study Of Heat Transfer In Rotary Desorbers Used To Remediate Contaminated Soils., Charles Alan Cook

LSU Historical Dissertations and Theses

A comprehensive heat transfer model is developed which describes heat transfer phenomena in rotary desorbers. This model predicts the temperatures of the solids bed and gases in the desorber and the rate of water evaporation from the solids. Emphasis is placed on describing the heat transfer process between the rotating wall of a desorber and the adjacent bed of solids. A heat-balance integral method is used to model heat conduction from the wall to adjacent wet bed particles. This solution includes the effects of water evaporation near the wall and a thermal contact resistance between the wall and the first …

Object-Oriented Modeling And Design Using Delta, An Incremental Design Language., Nancy Kay Gautier Jan 1993

Object-Oriented Modeling And Design Using Delta, An Incremental Design Language., Nancy Kay Gautier

LSU Historical Dissertations and Theses

Object-oriented technology has opened the doors for many new ideas in system development. The object-oriented paradigm has produced many new object-oriented programming languages. As with any new methodology, a need for formalism arises to remove ambiguities and inconsistencies and to bring a sense of continuity to software design. Formal languages provide a sound basis for software development throughout the software life cycle. This work presents a set of characteristic features for object-oriented design languages and defines a formal object-oriented design language, DELTA. The rapidly changing face of software has led to an ever increasing need to update out-of-date methods and …

How The Jones Polynomial Gives Rise To Physical States Of Quantum General Relativity, Bernd Brügmann, Rodolfo Gambini, Jorge Pullin Jan 1993

How The Jones Polynomial Gives Rise To Physical States Of Quantum General Relativity, Bernd Brügmann, Rodolfo Gambini, Jorge Pullin

Faculty Publications

Solutions to both the diffeomorphism and the hamiltonian constraint of quantum gravity have been found in the loop representation, which is based on Ashtekar's new variables. While the diffeomorphism constraint is easily solved by considering loop functionals which are knot invariants, there remains the puzzle why several of the known knot invariants are also solutions to the hamiltonian constraint. We show how the Jones polynomial gives rise to an infinite set of solutions to all the constraints of quantum gravity thereby illuminating the structure of the space of solutions and suggesting the existance of a deep connection between quantum gravity …

Escape Of Gravitational Radiation From The Field Of Massive Bodies, Richard H. Price, Jorge Pullin, Prasun K. Kundu Jan 1993

Escape Of Gravitational Radiation From The Field Of Massive Bodies, Richard H. Price, Jorge Pullin, Prasun K. Kundu

Faculty Publications

We consider a compact source of gravitational waves of frequency, in or near a massive spherically symmetric distribution of matter or a black hole. Recent calculations have led to apparently contradictory results for the influence of the massive body on the propagation of the waves. We show here that the results are in fact consistent and in agreement with the standard viewpoint in which the high-frequency compact source produces the radiation as if in a flat background, and the background curvature affects the propagation of these waves. © 1993 The American Physical Society.

Reliability And Validity Of The Teen Substance Abuse Rating Scale., Brett Elliott Hemstreet Jan 1993

Reliability And Validity Of The Teen Substance Abuse Rating Scale., Brett Elliott Hemstreet

LSU Historical Dissertations and Theses

This study used 57 adolescent substance abusers receiving treatment and 510 adolescent controls in a validation of the Teen Substance Abuse Rating Scale (TSARS; Hemstreet, 1991). The TSARS was originally designed as a relatively brief, easy to read self-report questionnaire to discriminate between adolescent substance abusers and nonabusers. The 92 items of the TSARS represent specific behaviors that are answered in a Yes/No format. The TSARS was examined to determine if it would meet validity criteria presented by Winters (1990) and Swadi (1990), as well as those presented in the Standards for Educational and Psychological Testing (APA, 1985). A principal …
