This thesis analyzed the effects of speaking style, either read or spontaneous speech, on vowel spaces and long-term formant distributions (LTFD), alongside other sociolinguistic effects (sex and age). The results indicated that formant frequencies were indeed modulated by speaking style, with vowel spaces showing centralization during spontaneous speech compared to read speech. LTFD showed an increase in frequency during spontaneous speech over read speech, particularly in the third long...
Show moreThis thesis analyzed the effects of speaking style, either read or spontaneous speech, on vowel spaces and long-term formant distributions (LTFD), alongside other sociolinguistic effects (sex and age). The results indicated that formant frequencies were indeed modulated by speaking style, with vowel spaces showing centralization during spontaneous speech compared to read speech. LTFD showed an increase in frequency during spontaneous speech over read speech, particularly in the third long-term formant (LTF3). Sex and age were both significant factors for both vowel space and LTFD, with males and older speakers producing lower frequencies. The examination of the effect of speech style, sex and age on vowel space and LTFD allows us to better understand the factors that play a role in speech production.

The equivalent end deflections and rotations for beams with integral, but dissimilar, elastic supports were determined. Finite element analysis was used to generate the midsurface deflection of the beam.

Show moreThe equivalent end deflections and rotations for beams with integral, but dissimilar, elastic supports were determined. Finite element analysis was used to generate the midsurface deflection of the beam. Numerical results were then fit to the analytical solution for the deflection of a beam, yielding the equivalent end slope resulting from deformations in the support. The lateral deflection at the support was available directly from the finite element calculation. The approach used for modeling of the supports is discussed. It was found that the slope and deflection at the support increase as the relative stiffness of the support decreases, as would be expected. Results are presented for both cantilever and beams with fixed ends, are valid for slender beams with small deflection.

Show moreThe cross-validated classification accuracy of predictive discriminant analysis (PDA) and logistic regression (LR) models was compared for the two-group classification problem. Thirty-four real data sets varying in number of cases, number of predictor variables, degree of group separation, relative group size, and equality of group covariance matrices were employed for the comparison. PDA models were built based on assumptions of multivariate normality and equal covariance matrices, and cases were classified using Tatsuoka's (1988, p. 351) minimum chi square rule. LR models were built using the International Mathematical and Statistical Library (IMSL) subroutine Categorical Generalized Linear Model (CTGLM), available with the 32-bit Microsoft Fortran v4.0 Powerstation. CTGLM uses a nonlinear approximation technique (Newton-Raphson) to determine maximum likelihood estimates of model parameters. The group with the higher log-likelihood probability was used as the LR prediction. Cross-validated hit-rate accuracy of PDA and LR models was estimated using the leave-one-out procedure. McNemar's (1947) statistic for correlated proportions was used in the statistical comparisons of PDA and LR hit rate estimates for separate-group and total-sample proportions (z = 2.58, a =.01). Total-sample and separate-group cross-validated classification accuracy obtained by PDA was not significantly different from that obtained by LR in any of the 31 data sets for which maximum likelihood estimates of LR model parameters could be calculated. This was true regardless of assumptions made about population sizes (i.e., equal or unequal). Neither theoretical nor data-based considerations were helpful in predicting these results. Although it does not appear from these data to make a difference which classification model is used, use of the method described in this study for comparing PDA and LR models will enable researchers to select the optimal classification model for a specific data set, regardless of data conditions.

Show moreThe mathematical theory of nding a basis of shortest possible vectors in a given lattice L is known as reduction theory and goes back to the work of Lagrange, Gauss, Hermite, Korkin, Zolotarev, and Minkowski. Modern reduction theory is voluminous and includes the work of A. Lenstra, H. Lenstra and L. Lovasz who created the well known LLL algorithm, and many other researchers such as L. Babai and C. P. Schnorr who created signi cant new variants of basis reduction algorithms. The shortest vector (SVP) and closest vector (CVP) problems, presently considered intractable, are algorithmic tasks that lie at the core of many number theoretic problems, integer programming, nding irreducible factors of polynomials, minimal polynomials of algebraic numbers, and simultaneous diophantine approximation. Lattice basis reduction also has deep and extensive connections with modern cryptography, and cryptanalysis particularly in the post-quantum era. In this dissertation we study and compare current systems LLL and BKZ, and point out their strengths and drawbacks. In addition, we propose and investigate the e cacy of new optimization techniques, to be used along with LLL, such as hill climbing, random walks in groups, our lattice di usion-sub lattice fusion, and multistage hybrid LDSF-HC technique. The rst two methods rely on the sensitivity of LLL to permutations of the input basis B, and optimization ideas over the symmetric group Sm viewed as a metric space. The third technique relies on partitioning the lattice into sublattices, performing basis reduction in the partition sublattice blocks, fusing the sublattices, and repeating. We also point out places where parallel computation can reduce runtimes achieving almost linear speedup. The multistage hybrid technique relies on the lattice di usion and sublattice fusion and hill climbing algorithms. Unlike traditional methods, our approach brings in better results in terms of basis reduction towards nding shortest vectors and minimal weight bases. Using these techniques we have published the competitive lattice vectors of ideal lattice challenge on the lattice hall of fame. Toward the end of the dissertation we also discuss applications to the multidimensional knapsack problem that resulted in the discovery of new large sets of geometric designs still considered very rare. The research introduces innovative techniques in lattice basis reduction theory and provides some space for future researchers to contemplate lattices from a new viewpoint.

In the past, consideration of myth structure has generally been through the examination of particular component relationships. The present study, wit·h the aid of computer application, attempts to define a network of term relationships and thus integrate numerous mediating systems associated with the final expression. The proposed methodology is demonstrated through the analysis of contemporary Mesoamerican myths.

Show moreThis study investigates the technical feasibility of solar pond power generation in the state of Florida. A onedimensional model is used to analyze three different modes of operation of the pond as follows: The steady state analysis determines the maximum overall efficiency of the pond, optimum load and optimum brine temperature to be extracted. The steady periodic analysis determines the performances of the pond subjected to seasonal variation. The transient analysis determines the time necessary for the pond to reach the optimum temperature. The study determines that for the Miami, Orlando, and Jacksonville locations, for a pond with 1.5 m NCZ depth using data for the state of Florida, the maximum overall efficiency is between 3.30 and 3.32 percent with an optimum load between 33 and 35 W/m2 and brine temperature to be extracted between 85 to 92°C. The above results assume that the power plant efficiency would be equal to that of a Carnot cycle efficiency. Since, in practice Carnot efficiency cannot be achieved the actual efficiency will be lower than the above values.

Show moreStructuralism's Critique of the Romantic Myth of the Author is aimed at the Romantic concept of the author as a special individual possessed of unique sensibilities and God-like powers of creation. The structuralist analysis of this myth is an attempt to decompose - to separate into its component parts - the Romantic image of the author. This act of decomposition enables structuralism to demonstrate the construction of this myth and to suggest its implausability from a perspective informed by structuralist theory. In the course of this analysis, structuralism is able to suggest some of the functions of the myth within literature as well as within contemporary Western culture.

Vanadyl etioporphyrin I has C4 symmetry and is chiral. Hence, it should be resolvable. Attempts were made to resolve it into its enantiomers by chromatography using optically active ads or bents since it has no functional groups which can be used to form isolable diastereomers. Numerous optically active ads or bents were tried in the pure state and adsorbed on silica gel. In most cases the Rf values were either close to zero or close to one, making resolution impossible.

Show moreVanadyl etioporphyrin I has C4 symmetry and is chiral. Hence, it should be resolvable. Attempts were made to resolve it into its enantiomers by chromatography using optically active ads or bents since it has no functional groups which can be used to form isolable diastereomers. Numerous optically active ads or bents were tried in the pure state and adsorbed on silica gel. In most cases the Rf values were either close to zero or close to one, making resolution impossible. Only in the case of lactose on silica gel and using benzene as the solvent was the Rf value such (approx. 0. 52) that resolution seemed, at least, possible. However, no optically active fraction could be obtained on column chromatography. Since oxygen exchange between the vanadyl group of vanadyl etioporphyrin I and water might occur and cause rapid interconversion of the enantiomers (hence racemization), thereby vitiating resolution attempts, the possibility of such oxygen exchange was investigated under a variety of conditions by means of H2 O^18 . The I. R. method was used to detect any such exchange (VO^18 vs. VO^16). It was found that vanadyl etioporphyrin I fails to undergo any measurable exchange under all the conditions tried, although the vanadyl ion of vanadyl sulfate does undergo exchange.

In performing measurements of power flow or structural intensity, it would be required that the components associated with the in-plane or out-of-plane waves be identified. Using a frequency wavenumber approach, the measured structural intensity can be decomposed into its different wave components. In this thesis, simulated structural intensity measurements are presented to demonstrate the use of this frequency wavenumber technique. The results obtained show the distribution of the structural intensity into the wave components. The implementation of this technique using a laser based instrument is discussed. The required characteristics of the instrument, the number of channels, the spacing between the channels, and the phase accuracy, are described. Also, a table to perform the scanning for the frequency wavenumber analysis is presented.

Show moreThere is an ancient genre of discourse which has served primarily to rationalize masculine privilege. The aim of the authors of this discourse has been to establish the "natural" superiority of men by methodically certifying the "natural" inferiority of women. This genre of discourse is misogynous discourse. Designed to amplify and expose the degrading effect of misogynous discourse on the human psyche, this analysis of misogynous language and discourse is achieved through a critical technique known as defamiliarization, which allows the reader to examine the discourse from a new and incongruous perspective. In this instance defamiliarization is accomplished simply by reversing the gender of the language, making it seem as though it was written by women about men, instead of by men about women. The final goal of this study is to demythologize this language and thereby render it neutral.

Capacitance-Voltage curves were generated using the high frequency and quasistatic techniques. The energy distribution of surface states, calculated by the Castagne technique, was dependent upon exposure temperature. The total number of radiation induced surface states, NTss saturated, and was the same for both exposure temperatures. The radiation induced additional acceptor surface states with energies near the valence band. No difference was observed in the oxide charge density between samples exposed at T = 77°K and T = 298°K. The flat band voltage shift saturated at a dose of approximately 0.55 mrad(Si). A generation-recombination model is used for the oxide and interface charge build up at both temperatures, to calculate the maximum depth of radiation induced charges, d. The experimentally determined values of NTss and d are consistent with the generation-recombination model.

Show moreThe purpose of this study was to develop and explore the factor structure of the Student Engagement in Social–Emotional Learning Skills (SE-SELS) survey, a newly designed assessment that assesses students’ knowledge and use of five social–emotional learning skills (self-awareness, self-management, social awareness, relationship skills and responsible decision making) aligned with the framework of the Collaborative for Academic, Social, and Emotional Learning. The SE-SELS survey includes 20 items and takes approximately 5 min to complete. Participants were 359 students in Grades 6–8 at one university-affiliated laboratory school serving students in kindergarten through eighth grade. The instrument was explored through exploratory factor analysis, which determined that the strengths of relationships among variables was satisfactory and that the model overall had strong internal reliability (α = .90). All items were retained for the final SE-SELS survey (.41 ≤ α ≤ .75). Items linked to the relationship skills component and the self-management component were merged to create a four-factor model, which ABSTRACT was a better fit for the data overall and retained all five components addressed by the SESELS survey. There is at present a lack of reliable and valid instruments that measure the effectiveness of interventions and student outcomes related to social–emotional learning. The SE-SELS survey can thus help school counselors and other educators to determine the impact of social–emotional learning interventions and provide baseline and growth data for students. Follow-up studies are needed to support the reliability and validity of the SE-SELS survey.
