Data Mining And Knowledge Discovery: A Guided Approach Base On Monotone Boolean Functions, Vetle Ingvald Torvik Jan 2002

Data Mining And Knowledge Discovery: A Guided Approach Base On Monotone Boolean Functions, Vetle Ingvald Torvik

LSU Doctoral Dissertations

This dissertation deals with an important problem in Data Mining and Knowledge Discovery (DM & KD), and Information Technology (IT) in general. It addresses the problem of efficiently learning monotone Boolean functions via membership queries to oracles. The monotone Boolean function can be thought of as a phenomenon, such as breast cancer or a computer crash, together with a set of predictor variables. The oracle can be thought of as an entity that knows the underlying monotone Boolean function, and provides a Boolean response to each query. In practice, it may take the shape of a human expert, or it …

Evaluation Of Bacillus Thuringiensis Transgenic Field Corn For Management Of Louisiana Corn Pests, Boris A. Castro

LSU Doctoral Dissertations

Efficacy of Bt corn hybrids expressing an insecticidal delta-endotoxin through different transformation events was evaluated in Louisiana. Efficacy levels were determined for southwestern corn borer (SWCB), Diatraea grandiosella Dyar; sugarcane borer (SCB), Diatraea saccharalis (F.); corn earworm (CEW), Helicoverpa zea (Boddie); and fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith). Insect (neonates and third instars) susceptibility was evaluated on Bt and non-Bt corn plants (V6 and R1 stages) in field plots and plant tissue in laboratory studies. Bt corn hybrids with MON810 and CBH351 transformation events sustained significantly (P < 0.05) less injury caused by SWCB, SCB, and FAW during infestations at mid-whorl stage. SWCB, SCB, and CEW infestations during silking stage were significantly reduced in Bt hybrids with the MON810 event. However, CEW infestations …

High Resolution Modeling Of Transport In Porous Media, Guangli Liu Jan 2002

High Resolution Modeling Of Transport In Porous Media, Guangli Liu

LSU Doctoral Dissertations

This dissertation presents research on the pore-level modeling of transport in porous media. The focus of this work is on high-resolution modeling, a rigorous approach that represents detailed geometry and first-principle physics at the streamline scale. Three major topics are presented in this dissertation: an efficient approach for solving Stokes flow in essentially arbitrary disordered porous media, high-resolution versus network simulations of dispersion phenomena, and a stochastic model for solving interfacial mass transfer from source spheres in porous media. First an approach was developed for solving the Stokes flow problem in a comparatively large, very heterogeneous two-dimensional porous media with …

Lmx Dyad Agreement: Construct Definition And The Role Of Supervisor/Subordinate Similarity And Communication In Understanding Lmx, Barbara Dale Minsky Jan 2002

Lmx Dyad Agreement: Construct Definition And The Role Of Supervisor/Subordinate Similarity And Communication In Understanding Lmx, Barbara Dale Minsky

LSU Doctoral Dissertations

Much LMX research is predicated upon the assumption that the quality of the supervisor-subordinate relationship is predictive of important organizational and individual outcomes. I propose, however, that leader-member agreement in perception about the nature of the relationship as well as the type of relationship itself is important. I have identified and examined some of the theoretically relevant determinants of leader and member perceptual agreement regarding the nature of their LMX relationship. I hypothesized that relational demography, values, perceived similarity, communication, feedback, and role clarity are related to LMX perceptual agreement. Data was collected through surveys personally administered to employees at …

Improvement Of Resonant Harmonic Filter Effectiveness In The Presence Of Distribution Voltage Distortion, Herbert L. Ginn Jan 2002

Improvement Of Resonant Harmonic Filter Effectiveness In The Presence Of Distribution Voltage Distortion, Herbert L. Ginn

LSU Doctoral Dissertations

Resonant harmonic filters (RHFs), are the most common devices installed in distribution systems for reducing distortion caused by harmonic generating loads. When such filters are applied in systems with a distorted distribution voltage their effectiveness may decline drastically. This dissertation explores the causes of degradation of RHFs effectiveness and suggests methods of their improvement both by optimization algorithms and by modification of the filter structure. An optimization based design method is developed for the conventional RHF. It takes into consideration the interaction of the filter with the distribution system and provides a filter which gives the maximum effectiveness with respect …

Mode Specific Photoionization Dynamics In Polyatomic Molecules, Gerald Jeffery Rathbone Jan 2002

Mode Specific Photoionization Dynamics In Polyatomic Molecules, Gerald Jeffery Rathbone

LSU Doctoral Dissertations

The work presented in this dissertation presents new work on polyatomic photoionization. In these investigations, the broad range behavior of both allowed and forbidden vibrational modes in linear triatomic systems were studied to understand mode specific aspects of photoionization. The current study is made possible by the experimental strategy of exploiting high resolution photoelectron spectroscopy and the high brightness of third generation synchrotron radiation sources. The data is taken typically tens of eV’s past the ionization potential. The strategy that I employ is to probe alternative vibrational modes which are frequently affected differently following resonant ionization. Such vibrationally resolved data …

Capillary And Microdevice Electrophoretic Tools For Genetic Analyses: Heteroduplex Analysis For Tuberculosis Drug Susceptibility And Ligase Detection Reaction For Colorectal Cancer Detection, Gloria Thomas

LSU Doctoral Dissertations

The traditional format of electrophoresis, the slab gel, is quickly being replaced by capillary and microdevice platforms, which offer improvements in cost, resolution, speed, quantitation and automation in genetic analyses. These techniques also employ a variety of separation matrices while the slab gel is limited to agarose and polyacrylamide. The research presented here explores the use of these electrophoretic formats for the detection of single nucleotide mutations using two genetic models associated with human disease. Slab gel based heteroduplex analysis (HDA), a popular mutation scanning method, uses a specially designed universal heteroduplex generator (UHG) containing controlled variation to enhance the …

Optimal Channel Equalization For Filterbank Transceivers In Presence Of White Noise, Ehab Farouk Badran Jan 2002

Optimal Channel Equalization For Filterbank Transceivers In Presence Of White Noise, Ehab Farouk Badran

LSU Doctoral Dissertations

Filterbank transceivers are widely employed in data communication networks to cope with inter-symbol-interference (ISI) through the use of redundancies. This dissertation studies the design of the optimal channel equalizer for both time-invariant and time-varying channels, and wide-sense stationary (WSS) and possible non-stationary white noise processes. Channel equalization is investigated via the filterbank transceivers approach. All perfect reconstruction (PR) or zero-forcing (ZF) receiver filterbanks are parameterized in an affine form, which eliminate completely the ISI. The optimal channel equalizer is designed through minimization of the mean-squared-error (MSE) between the detected signals and the transmitted signals. Our main results show that the …

A Variable Response Time Lag Module For Car Following Models Using Fuzzy Set Theory, Yilmaz Hatipkarasulu Jan 2002

A Variable Response Time Lag Module For Car Following Models Using Fuzzy Set Theory, Yilmaz Hatipkarasulu

LSU Doctoral Dissertations

Since the 1950s, car following phenomena have been studied and analyzed, resulting in various models and algorithms. In general, the car following process has been defined as a stimulus-response relationship in which the driver of the following vehicle reacts to the actions of the lead vehicle after a time lag. One of the fundamental assumptions that underlie car following theory is that the driver response time lag is always a constant value for the driver at all times, regardless of level of detail of the model. Assumption of a constant time lag value introduces a number of broad assumptions however, …

Sorority Rituals : Rites Of Passage And Their Impact On Contemporary Sorority Women, Mari Ann Callais Jan 2002

Sorority Rituals : Rites Of Passage And Their Impact On Contemporary Sorority Women, Mari Ann Callais

LSU Doctoral Dissertations

Very little research has been conducted to assess the effects of sorority membership on undergraduate sorority women. While there have been numerous studies conducted concerning fraternity men, there has been limited research concerning sorority women only and no studies that explore the effects of ritual on the sorority experience. Does ritual have an impact on the values and behavior of contemporary sorority women? Addressing this question requires an in-depth understanding of the role of the sorority experience and examination of the experience to determine if it provides to its membership what it is intended to provide. Based on research conducted …

Synthesis And Study Of New Materials For The Visual Detection Of Biomolecules, Ming He Jan 2002

Synthesis And Study Of New Materials For The Visual Detection Of Biomolecules, Ming He

LSU Doctoral Dissertations

The visual determination of saccharides has been of interest for well over a century. Sugars are a relatively challenging class of compounds to analyze. They exhibit great structural similarity as well as transparency in the visible region. The sensing of specific saccharides could aid the monitoring of disease or industrial fermentation products. Herein I present new methods allowing for simple and rapid visual detection of sialic acid, fructose and a homologous series of prototypical neutral oligosaccharides, the linear maltodextrins, containing up to seven glucose residues. The new methods allow for selective color detection of fructose in a large excess of …

"Uncouth Shapes" And Sublime Human Forms Of Wordsworth's The Prelude In The Ligh Of Berdyaev's Personalistic Philosophy Of Freedom, Elena V. Haltrin Khalturina Jan 2002

"Uncouth Shapes" And Sublime Human Forms Of Wordsworth's The Prelude In The Ligh Of Berdyaev's Personalistic Philosophy Of Freedom, Elena V. Haltrin Khalturina

LSU Doctoral Dissertations

In complementary response to socio-historisists who discuss the concept of "freedom" in William Wordsworth's poetry as determined from without — be it by socio-historical conditions, gender, or imposed ideology — I draw from the theory of Nicholas Berdyaev, one of the prominent continental existentialists of the twentieth century, tracing the development of Wordsworth's understanding of freedom towards "genuine liberty" as progressively determined from within. Thus focusing on "existentia" rather than "essentia," I pay particular attention to shaping inner efforts and developing visions of the growing and conscious personality as they are described in The Prelude. Wordsworth hinges his ability to …

Synthesis, Characterization, And Applications Of Novel Pseudostationary Phases In Micellar Capillary Electrophoresis For Separation Of Chiral And Archiral Compounds H[Electronic Resource], Cevdet Akbay

LSU Doctoral Dissertations

The research presented in this dissertation involves the synthesis, characterization, and the use of novel surfactants, including both micelles and vesicles, as pseudostationary phases in micellar capillary electrophoresis (MCE) for the separation of achiral and chiral compounds. Separation of environmental pollutants such as 2 to 6-ring polycyclic aromatic hydrocarbons (PAHs) was achieved using poly(sodium undecylenic sulfate). A baseline separation of all 16 PAHs was possible for the first time in MCE by a single-surfactant system. In addition, a surfactant with a phosphated head group, i.e., di(2-ethylhexyl)phosphate (DEHP), was also introduced as a novel pseudostationary phase for separation of 21 weakly …

Experience-Based Language Acquisition: A Computational Model Of Human Language Acquisition, Brian Edward Pangburn Jan 2002

Experience-Based Language Acquisition: A Computational Model Of Human Language Acquisition, Brian Edward Pangburn

LSU Doctoral Dissertations

Almost from the very beginning of the digital age, people have sought better ways to communicate with computers. This research investigates how computers might be enabled to understand natural language in a more humanlike way. Based, in part, on cognitive development in infants, we introduce an open computational framework for visual perception and grounded language acquisition called Experience-Based Language Acquisition (EBLA). EBLA can “watch” a series of short videos and acquire a simple language of nouns and verbs corresponding to the objects and object-object relations in those videos. Upon acquiring this protolanguage, EBLA can perform basic scene analysis to generate …

Role Of Chondrocyte Apoptosis In The Pathogenesis Of Equine Osteoarthritis, Dae Young Kim Jan 2002

Role Of Chondrocyte Apoptosis In The Pathogenesis Of Equine Osteoarthritis, Dae Young Kim

LSU Doctoral Dissertations

Osteoarthritis (OA), a non-inflammatory, degenerative disease of articular cartilages, is a common cause of poor performance and early retirement in equine athletes. Pathologically, OA is characterized by matrix degradation and decreased chondrocyte numbers. A mechanical stress is believed to be the major etiologic factor of OA development. Recent studies have indicated that apoptosis is responsible for hypocellularity in OA cartilage and that chondrocyte death by apoptosis could directly contribute to matrix degradation. Increased nitric oxide (NO), a free radical, has been implicated as a cause of chondrocyte apoptosis. No studies, however, have been performed on chondrocyte apoptosis in equine OA. …

Aspects Of The Behavioral Ecology, Life History, Genetics, And Morophology Of The Hawaiian Kuhliid Fishes, Lori Keene Benson Jan 2002

Aspects Of The Behavioral Ecology, Life History, Genetics, And Morophology Of The Hawaiian Kuhliid Fishes, Lori Keene Benson

LSU Doctoral Dissertations

Flagtails, members of the Genus Kuhlia, are Indo-Pacific fishes found in marine and freshwater habitats. Known locally as āholehole, they are important food fishes in the Hawaiian Islands and were often used by Hawaiians in traditional ceremonies. Local fishermen have noted the presence of two morphotypes in Hawai'i, although at the beginning of this study only one species, Kuhlia sandvicensis, was identified in the scientific literature. For this dissertation research, morphological and DNA studies of the two morphotypes determined that two species of the genus Kuhlia do exist in Hawai'i. Subsequently, Randall and Randall (2001) published a revision of this …

An Empirical Analysis Of The Macroeconomic Effects Of Government Purchases, Eric Horent Jan 2002

An Empirical Analysis Of The Macroeconomic Effects Of Government Purchases, Eric Horent

LSU Doctoral Dissertations

This dissertation investigates the implications of different methods of identifying exogenous shocks to defense purchases for estimating the macroeconomic effects of shocks to government purchases. Four identification schemes are examined: the narrative approach of Ramey and Shapiro (1997), a more comprehensive narrative approach that tries to isolate exogenous reductions in defense purchases as well as exogenous increases in defense purchases, the Choleski decomposition, and long-run restrictions. The effects of alternative methods of identifying policy shocks are examined within two common VAR systems estimated over specific sample periods. The benchmark model includes four lagged values of defense purchases, real GDP, the …

Molecular Systematics, Phylogeography, And Population Genetics Of Xiphorhynchus (Aves: Dendrocolaptidae) In The Amazon Basin, Alexandre Aleixo Jan 2002

Molecular Systematics, Phylogeography, And Population Genetics Of Xiphorhynchus (Aves: Dendrocolaptidae) In The Amazon Basin, Alexandre Aleixo

LSU Doctoral Dissertations

Among those few hypotheses amenable to falsification by phylogenetic methods concerning the diversification of the Amazonian biota, three can be singled out because of their verifiable predictions: the riverine barrier, the gradient, and the basal trichotomy hypotheses. I used phylogenetic and population genetics methods to reconstruct the diversification history of the genus Xiphorhynchus (aves: Dendrocolaptidae) in Amazonia. First, I estimated the phylogeny of the entire genus Xiphorhynchus to test a key prediction of the gradient hypothesis; secondly, I documented phylogeographies of a superspecies associated with upland forest (X. spixii / elegans) and two species linked to floodplain forest (X. kienerii …

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt Jan 2002

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt

LSU Doctoral Dissertations

Research has found that athletes, particularly those involved in "aesthetically-oriented" sports, are at increased risk for engaging in unhealthy weight reduction practices and developing clinical eating disorders. Prevention studies of eating disorders have had some success, but there are very few published studies that address prevention in athletes. This study was designed as an eating disorders prevention program that targeted coaches as change agents. Cheerleading coaches at national or regional conferences attended an intervention workshop or a control workshop. Coaches who attended the intervention workshop received information regarding nutrition, eating disorders, and ways to manage athletes with eating disorders. They …

Production Of Transgenic Goats By Somatic Cell Nuclear Transfer, Brett C. Reggio Jan 2002

Production Of Transgenic Goats By Somatic Cell Nuclear Transfer, Brett C. Reggio

LSU Doctoral Dissertations

A series of experiments were conducted to produce transgenic goats by somatic cell nuclear transfer (NT). In all experiments, donor cells were electrically fused to enucleated metaphase II oocytes, then chemically activated. In a preliminary study to evaluate embryonic development following NT with proliferating or quiescent fibroblast or cumulus cells, significantly more embryos reconstructed with quiescent cumulus cells fused (77%) compared with proliferating cumulus cells (41%), proliferating fibroblasts (36%) or quiescent fibroblasts (37%). Improved development to the eight- to sixteen-cell stage was observed when fibroblast cells were serum starved (serum starved 39% vs. serum fed 15%). However, there was no …

Mixed-Symmetry Shell-Model Calculations In Nuclear Physics, Vesselin Gueorguiev Gueorguiev Jan 2002

Mixed-Symmetry Shell-Model Calculations In Nuclear Physics, Vesselin Gueorguiev Gueorguiev

LSU Doctoral Dissertations

Advances in computer technologies allow calculations in ever larger model spaces. To keep our understanding growing along with this growth in computational power, we consider a novel approach to the nuclear shell model. The one-dimensional harmonic oscillator in a box is used to introduce the concept of an oblique-basis shell-model theory. By implementing the Lanczos method for diagonalization of large matrices, and the Cholesky algorithm for solving generalized eigenvalue problems, the method is applied to nuclei. The mixed-symmetry basis combines traditional spherical shell-model states with SU(3) collective configurations. We test the validity of this mixed-symmetry scheme on 24Mg and …
