Racks, Quandles And Virtual Knots, Victor Samuel Nelson Jan 2002

Racks, Quandles And Virtual Knots, Victor Samuel Nelson

LSU Doctoral Dissertations

We begin with a brief survey of the theory of virtual knots, which was announced in 1996 by Kauffman. This leads naturally to the subject of quandles and quandle homology, which we also briefly introduce. Chapter 2 contains a proof in terms of Gauss diagrams that the forbidden moves unknot virtual knots. This chapter includes material which has appeared in the Journal of Knot Theory and its Ramifications and is reprinted here by permission of World Scientific Publishing. In chapter 3 (cowritten with my advisor R.A.Litherland) we confirm a conjecture of J.S.Carter et.al. that the long exact sequence in rack …

Tidal Dynamics In The Bab El Mandab Strait, Ewa Jarosz Jan 2002

Tidal Dynamics In The Bab El Mandab Strait, Ewa Jarosz

LSU Doctoral Dissertations

The Bab el Mandab Strait is where the transition occurs between two noticeably different tidal regimes: the Gulf of Aden, where tidal fluctuations are mixed and have a range in excess of 2 m, and the Red Sea, where the tides are principally semidiurnal and their range is less than 1 m. Within the Strait, observations collected between May of 1995 and July of 1997 indicate that tidal currents are a mixed type and dominant constituents are the K1 and M2. The vertical structure of the tidal currents is complicated, differs between semidiurnal and diurnal constituents, and …

A Factorization Approach For Solving The Hamilton-Jacobi Equations In Nonlinear Optimal Control, Mohammad Dikko Aliyu Jan 2002

A Factorization Approach For Solving The Hamilton-Jacobi Equations In Nonlinear Optimal Control, Mohammad Dikko Aliyu

LSU Doctoral Dissertations

The Hamilton-Jacobi equation (HJE) arose early in the last century in the study of the calculus of variation, classical mechanics and Hamiltonian systems. Recently, there has been a renewed interest in HJEs arising in various analysis and synthesis problems in systems theory. The HJE despite providing a necessary and sufficient condition for an optimal control, is very difficult to solve for general nonlinear systems, and therefore its application remained limited to linear systems. Yet, the HJE has been studied extensively in the literature from diverse areas of science and engineering, varying from mathematical physics, to mechanics, control theory, and to …

Exotic Integral Witt Equivalence Of Algebraic Number Fields, Changheon Kang Jan 2002

Exotic Integral Witt Equivalence Of Algebraic Number Fields, Changheon Kang

LSU Doctoral Dissertations

Two algebraic number fields K and L are said to be exotically integrally Witt equivalent if there is a ring isomorphism W(OK) ~ W(OL) between the Witt rings of the number rings OK and OL of K and L, respectively. This dissertation studies exotic integral Witt equivalence for totally complex number fields and gives necessary and sufficient conditions for exotic integral equivalence in two special classes of totally complex number fields.

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 …

Deformations Of The Fermion Realization Of The Sp(4) Algebra And Its Subalgebras, K. D. Sviratcheva, A. I. Georgieva, V. G. Gueorguiev, J. P. Draayer, M. I. Ivanov Oct 2001

Deformations Of The Fermion Realization Of The Sp(4) Algebra And Its Subalgebras, K. D. Sviratcheva, A. I. Georgieva, V. G. Gueorguiev, J. P. Draayer, M. I. Ivanov

Faculty Publications

With a view towards future applications in nuclear physics, the fermion realization of the compact symplectic sp(4) algebra and its q-deformed versions are investigated. Three important reduction chains of the sp(4) algebra are explored in both the classical and deformed cases. The deformed realizations are based on distinct deformations of the fermion creation and annihilation operators. For the primary reduction, the su(2) substructure can be interpreted as either the spin, isospin or angular momentum algebra, whereas for the other two reductions su(2) can be associated with pairing between fermions of the same type or pairing between two distinct fermion types. …

Artin-Schreier Families And 2-D Cyclic Codes, Cem Guneri Aug 2001

Artin-Schreier Families And 2-D Cyclic Codes, Cem Guneri

LSU Historical Dissertations and Theses

We start with the study of certain Artin-Schreier families. Using coding theory techniques, we determine a necessary and sufficient condition for such families to have a nontrivial curve with the maximum possible number of rational points over the finite field in consideration. This result produces several nice corollaries, including the existence of certain maximal curves; i.e., curves meeting the Hasse-Weil bound. We then present a way to represent two-dimensional (2-D) cyclic codes as trace codes starting from a basic zero set of its dual code. This representation enables us to relate the weight of a codeword to the number of …

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers Jul 2001

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers

LSU Historical Dissertations and Theses

Twenty pen-raised white-tailed deer (Odocoileus virginianus) were released into mixed pine-hardwood forest habitat in southeastern Louisiana to compare their seasonal diets to the diets of the wild white-tailed deer population. Microhistological analysis was used to estimate the botanical composition of fecal pellet samples collected from both populations of deer over four consecutive seasons. Wild and pen-raised deer diets were found to be an average of 75.18% similar during the entire year of the study, and were significantly associated during all seasons (P < 0.001), indicating that all deer foraged on similar plant taxa in similar proportions regardless of season. Both populations of deer were found to be predominantly browsers during all seasons, with browse and fruit accounting for a yearly average of >55% of deer diets. Results from this study indicate that rehabilitated or translocated deer released into new environments …

On The Meromorphic Extension Of The Spherical Functions On Noncompactly Causal Symmetric Spaces, G. Ólafsson, A. Pasquale Apr 2001

On The Meromorphic Extension Of The Spherical Functions On Noncompactly Causal Symmetric Spaces, G. Ólafsson, A. Pasquale

Faculty Publications

We determine integral formulas for the meromorphic extension in the λ-parameter of the spherical functions φλ on a noncompactly causal symmetric space. The main tool is Bernstein's theorem on the meromorphic extension of complex powers of polynomials. The regularity properties of φλ are deduced. In particular, the possible λ-poles of φλ are located among the translates of the zeros of the Bernstein polynomial. The translation parameter depends only on the structure of the symmetric space. The expression of the Bernstein polynomial is conjectured. The relation between the Bernstein polynomial and the product formula of the cΩ-function is analyzed. The conjecture …

Deformations Of The Boson Sp(4, R) Representation And Its Subalgebras, J. P. Draayer, A. I. Georgieva, M. I. Ivanov Apr 2001

Deformations Of The Boson Sp(4, R) Representation And Its Subalgebras, J. P. Draayer, A. I. Georgieva, M. I. Ivanov

Faculty Publications

The boson representation of sp (4, R) algebra and two distinct deformations of it, spq(4, R) and spt(4, R), are considered, as well as the compact and noncompact subalgebras of each. The initial as well as the deformed representations act in the same Fock space, H, which is reducible into two irreducible representations acting in the subspaces H+ and H- of H. The deformed representation of spq(4, R) is based on the standard q-deformation of the boson creation and annihilation operators. The subalgebras of sp(4, R) (compact u(2) and noncompact uε(1, 1) with ε = 0, ±) are also deformed …

Of Manatees, Mangroves, And The Mississippi River: Is There An Estuarine Signature For The Gulf Of Mexico?, R. Eugene Turner Apr 2001

Of Manatees, Mangroves, And The Mississippi River: Is There An Estuarine Signature For The Gulf Of Mexico?, R. Eugene Turner

Faculty Publications

Important parameters of estuarine variability include morphology, flushing times, nutrient loading rates, and wetland: water ratios. This variability both reflects and disguises underlying relationships between the physics and biology of estuaries, which this comparative analysis seeks to reveal, using the Gulf of Mexico (GOM) estuaries as a starting point. A question used to focus this analysis is: are the GOM estuaries unique? The GOM receives the Mississippi River, a uniquely large, world-class river, which dominates the freshwater and nutrient inflows to the GOM continental shelf, whose margins include 35 major estuarine systems. These GOM estuaries have 28% and 41% of …

A Note On Doubles Of Groups, Nadia Benakli, Oliver T. Dasbach, Yair Glasner, Brian Mangum Feb 2001

A Note On Doubles Of Groups, Nadia Benakli, Oliver T. Dasbach, Yair Glasner, Brian Mangum

Faculty Publications

Recently, Rips produced an example of a double of two free groups which has unsolvable generalized word problem. In this paper, we show that Rips's example fits into a large class of doubles of groups, each member of which contains F2×F2 and therefore has unsolvable generalized word problem and is incoherent. © 2001 Elsevier Science B.V.

Girls Who Would Be Gods: The Poetry Of Emily Dickinson, Elizabeth Bishop, And Sylvia Plath., Anna Lynn Priddy Jan 2001

Girls Who Would Be Gods: The Poetry Of Emily Dickinson, Elizabeth Bishop, And Sylvia Plath., Anna Lynn Priddy

LSU Historical Dissertations and Theses

Girls Who Would Be Gods: The Poetry of Emily Dickinson, Elizabeth Bishop, and Sylvia Plath charts the development of these three American poets, from concerns with ambition and competition that appear in their early poetry, letters and journals, to their later creation of myths surrounding themselves and the secondary worlds of their creation. With Plath's explicit wish that she might be God, Bishop's Crusoe-like exile that allows her to create imaginary realms and homes, and Dickinson's not entirely tentative proposal that she might well be the Biblical Eve, these poets indulged in imaginative re-creations of their worlds and their selves. …

The Russian Orthodox Church As A Symbol Of Right Order: A Voegelinian Analysis., Lee David Trepanier Jan 2001

The Russian Orthodox Church As A Symbol Of Right Order: A Voegelinian Analysis., Lee David Trepanier

LSU Historical Dissertations and Theses

I will use Eric Voegelin's "new science" of politics to examine whether the Russian Orthodox Church is a symbol of right order. By investigating symbols of order and disorder in Russia, we will be able to uncover the structures of consciousness of the Russian Orthodox Church leadership. The examination of the experiences of man's consciousness will in turn reveal whether he and his society are ordered correctly or incorrectly. The explanation of symbols of order and disorder and the experiences behind these symbols is presented thoroughly in the first chapter of this dissertation. The chapter will conclude with an explanation …

Effects Of Bilingualism On Cognitive Processing In Adults., Christy J. Witt Jan 2001

Effects Of Bilingualism On Cognitive Processing In Adults., Christy J. Witt

LSU Historical Dissertations and Theses

The primary objective of this dissertation was to empirically test the implications of the code-switching hypothesis (Peal & Lambert, 1962) for nonlinguistic cognitive abilities in bilingual adults. It was hypothesized that bilinguals, by virtue of their ability to switching between two linguistic systems, may enjoy cognitive advantages in the nonlinguistic domain for tasks that require abilities related to language switching. It was postulated that the underlying mechanisms of code switching are the bilingual's abilities to inhibit the processing of irrelevant information and activate previously suppressed information. To determine if a bilingual advantage exists for these abilities, bilingual and monolingual adults …

Improved Matrix-Assisted Laser Desorption/Ionization Linear Time-Of-Flight Mass Spectrometry Of Oligonucleotides And Nucleic Acids Via Matrix Additives And Sample Preparatory Technique., Tracey Arlene Simmons Jan 2001

Improved Matrix-Assisted Laser Desorption/Ionization Linear Time-Of-Flight Mass Spectrometry Of Oligonucleotides And Nucleic Acids Via Matrix Additives And Sample Preparatory Technique., Tracey Arlene Simmons

LSU Historical Dissertations and Theses

There are two prominent problems recurrent during matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis of oligonucleotides: cation adduction and low molecular ion stability. It has been found that the use of organic base solutions of high gas-phase proton affinity, as used previously in electrospray ionization mass spectrometry (ESI-MS), can significantly reduce the cation adduction problem during MALDI-MS. It is proposed that the organic base solutions compete with alkali metal cations for binding to the phosphodiester backbone of the oligonucleotide upon transfer into the gas phase. A comparison of the utility of adding an organic base solution, such as imidazole, triethylamine …

A Hierarchical Shape Representation By Convexities And Concavities And Its Application To Shape Matching., Gustavo Martinez Jan 2001

A Hierarchical Shape Representation By Convexities And Concavities And Its Application To Shape Matching., Gustavo Martinez

LSU Historical Dissertations and Theses

Shape contains information. The identification and extraction of this information is not straightforward and is the main problem of Shape Analysis. The current trend of manipulating visual information, makes this problem more important. The abundant work published about shape analysis can be classified into two main approaches: statistical shape analysis and structural shape analysis. The structural approach was proposed around thirty years ago by K. S. Fu. The large amount of works published since then, prove the difficulty of defining a universal set of primitives. The structural description of shape is based on the assumption that shape recognition is a …

Shell Model Description Of Normal Parity Bands In Heavy Deformed Nuclei., Gabriela Popa Jan 2001

Shell Model Description Of Normal Parity Bands In Heavy Deformed Nuclei., Gabriela Popa

LSU Historical Dissertations and Theses

The low-energy spectra and electromagnetic transition strengths in 160,162,164Dy, 156,158,160Gd, and 168Er are described in the framework of the pseudo-SU(3) model. The Hamiltonian includes spherical single-particle energies, the Quadrupole-quadrupole interaction, and proton and neutron pairing terms with the strengths of these interaction fixed from systematics. The strengths of an additional four rotor-like terms that are included in the Hamiltonian, which do not mix SU(3) representations and induce only small changes in the spectra, were allowed to vary and a consistent set of these parameters was found. Proton and neutron degrees of freedom are considered explicitly by building the basis states …

Red Morningglory (Ipomoea Coccinea L.) And Sugarcane Response To Soil-Applied Herbicides., Blaine Joseph Viator Jan 2001

Red Morningglory (Ipomoea Coccinea L.) And Sugarcane Response To Soil-Applied Herbicides., Blaine Joseph Viator

LSU Historical Dissertations and Theses

Laboratory and greenhouse studies were conducted to determine if reported red morningglory (Ipomoea coccinea L.) control failures with atrazine in sugarcane are due to triazine-resistant mutants. Terminal fluorescence of leaf material from locations with and without a history of atrazine use increased after treatment with atrazine, indicating electron transport inhibition and hence, triazine susceptibility. Postemergence (POST) application of atrazine controlled plants from all populations at least 99%, supporting findings of the fluorescence assay. A field study was conducted to evaluate red morningglory control and sugarcane injury with herbicides applied at layby. At 45 days after treatment (DAT), control with sulfentrazone …

Center Vortices In Confinement., Viorel-Andrei Alexandru Jan 2001

Center Vortices In Confinement., Viorel-Andrei Alexandru

LSU Historical Dissertations and Theses

The confinement property of quarks is still one of the puzzles of today's physics. Although QCD is believed to accurately describe the interaction between quarks, due to the peculiar nature of the theory we are still unable to prove that it confines the quarks. Most analytical efforts in QCD are based on perturbative techniques which are useless in studying confinement. Lattice gauge theory enables us to get non-perturbative results. We use lattice techniques to investigate one of the proposed mechanisms of quark confinement, namely the center vortex idea. We first present a cursory introduction to lattice theory and the methods …
