Diversity combining ARQ over the m(> 2)-ary unidirectional channel

Creator:: Elarief, Noha
Abstract:: In diversity combining automatic repeat request (ARQ), erroneous packets are combined together forming a single, more reliable, packet. In this thesis, we give a diversity combining scheme for the m-ary unidirectional channel. A system using the given scheme with a t-unidirectional error detecting code is able to correct up to...

Zeros of Certain Combinations of Products of Eisenstein Series

Creator:: Klangwang, Jetjaroen
Abstract:: In this dissertation, we begin by presenting the result of F. K. C. Rankin and Swinnerton-Dyer on the location of the zeros of the Eisenstein series for the full modular group in the standard fundamental domain. Their simple but beautiful argument shows that all zeros are located on the lower...

Primal Matter : Deep Objects in Historical Accounts of the Glanton Gang

Creator:: Schauer, Austin A.
Abstract:: The question of deep time has been widely debated in the field of American Literature, with scholar Wai Chee Dimock arguing that a deep time perspective puts the chronology of different nations against one another. However, this argument has not adequately addressed the issue of how deep time theories would...

Parental accounts of a child's death : influences on parental identity and behavior

Creator:: Brotherson, Sean E.
Abstract:: One of the most powerful and life-changing events that can occur in the life of a family is the death of a child. Researchers who have studied death and bereavement suggest that a child's death has a dramatic impact on parents. However, little is known about the ways in which...

Existence of Eta-Quotients for Squarefree Levels and Modular Type Supercongruences for Hypergeometric Functions

Creator:: Allen, Michael
Abstract:: In this dissertation, we consider two problems in number theory, both relating to modular forms. First we consider when a given modular form can be expressed as a quotient in Dedekind's $\eta$ function. Rouse and Webb \cite{RW} have determined the integers $N \leq 500$ such that the graded ring of...

On Small Heights of Totally p-adic Numbers

Creator:: Stacy, Emerald T.
Abstract:: The height of an algebraic number A is a measure of how arithmetically complicated A is. We say A is totally p-adic if the minimal polynomial of A splits completely over the field of p-adic numbers. In this paper, we investigate what can be said about the smallest nonzero height...

Overpartition Ranks, Cranks, and Frobenius Representations

Creator:: Morrill, Thomas
Abstract:: We generalize overpartition rank and crank generating functions to obtain k-fold variants, and give a combinatorial interpretation for each. The k-fold crank generating function is interpreted by extending the first and second residual cranks to a natural infinite family. The k-fold rank generating functions generate two families of buffered Frobenius...

New Families of pseudo-Anosov Homeomorphisms with Vanishing Sah-Arnoux-Fathi Invariant

Creator:: Do, Hieu Trung
Abstract:: Translation surfaces can be viewed as polygons with parallel and equal sides identified. An affine homeomorphism φ from a translation surface to itself is called pseudo-Anosov when its derivative is a constant matrix in SL₂(R) whose trace is larger than 2 in absolute value. In this setting, the eigendirections of...

Continued fractions and the divisor at infinity on a hyperelliptic curve : examples and order bounds

Creator:: Daowsud, Katthaleeya
Abstract:: We use the theory of continued fractions over function fields in the setting of hyperelliptic curves of equation y²=f(x), with deg(f)=2g+2. By introducing a new sequence of polynomials defined in terms of the partial quotients of the continued fraction expansion of y, we are able to bound the sum of...

Credit cards : understanding international graduate student consumers

Creator:: Punjavat, Tapin
Abstract:: This study examined graduate international students' knowledge, attitudes, experiences, practices, and satisfaction relating to credit cards. Based on the literature, international students attending U.S. colleges and universities were considered an important population to study because of: (1) internationalization of credit cards and (2) the lack of credit card research on...

Optoelectronic properties of organic semiconductor materials : from bulk to single molecule

Creator:: Shepherd, Whitney E. B.
Abstract:: The behavior and application of organic semiconductor materials depend strongly on their molecular structure, and molecular interactions. Several studies of intermolecular interactions in functionalized polyacene materials are presented. The degree and onset of aggregation of a functionalized anthradithiophene derivative was studied as a function of concentration in two different host...

Analysis and modeling of lossy planar optical waveguides and application to silicon-based structures

Creator:: Remley, Catherine A.
Abstract:: This work is concerned with the modeling and analysis of lossy planar dielectric optical waveguides. Loss mechanisms which affect propagation characteristics are reviewed, and various representations of the propagation constant in the lossy case are defined. Waveguide structures which are susceptable to absorption and/or to leakage loss, in particular silicon-based...

Maximal operators along surfaces of revolution

Creator:: Le, Hung Viet
Abstract:: The study of differentiation of integrals has led to the study of maximal functions. In the development of harmonic analysis, the most powerful result connected with Lebesgue's theorem was that of the Hardy-Littlewood Maximal Theorem. This maximal theorem implies Lebesgue's theorem, and the maximal function and its variants have played...

Limited magnitude error control codes

Creator:: Elarief, Noha
Abstract:: A relatively new model of error control is the limited magnitude error over high radix channels. In this error model, the error magnitude does not exceed a certain limit known beforehand.

Periodicity and Partition Congruences

Creator:: Al-Saedi, Ali Hammood
Abstract:: In this note, we generalize recent work of Mizuhara, Sellers, and Swisher that gives a method for establishing restricted plane partition congruences based on a bounded number of calculations. Using periodicity for partition functions, our extended technique could be a useful tool to prove congruences for certain types of combinatorial...

Algebraic Pappus Curves

Creator:: Hatase, Tatsuhiko
Abstract:: We show that Pappus Curves, introduced by R. Schwartz to study his dynamical system in the real projective plane generated by iterated applications of the classical Pappus Theorem, are algebraic exactly in the linear case. Our approach is to use properties of projective curves such as singular points, genus, number...

A thin codimension-one decomposition of the Hilbert Cube

Creator:: Phon-On, Aniruth
Abstract:: For cell-like upper semicontinuous(usc) decompositions G of finite dimensional manifolds M, the decomposition space M/G turns out to be an ANR provided M/G is finite dimensional ([Dav07], page 129 ). Furthermore, if M/G is finite dimensional and has the Disjoint Disks Property (DDP), then M/G is homeomorphic to M ([Dav07],...
