Al/ti(x)w(1-X) Metal/diffusion-Barrier Systems: Interfacial Reaction Paths and Kinetics as a Function of Composition and Microstructure
TiW layers, 165 $\pm$ 25 nm thick, were grown on MgO(001), SiO$\sb2$ and Si(001) substrates by ultra-high vacuum (UHV) magnetron sputter deposition. Al overlayers, 190 $\pm$ 10 nm thick, were then deposited without breaking vacuum. TiW films deposited in Ar were found by Rutherford backscattering …

The Effect of Physical Activity Levels on Hydration Markers in Non-Athletic Free-Living Individuals
<p>Higher levels of physical activity requires increased fluid intake due to increased water losses via sweating. PURPOSE: To determine the effect of physical activity on hydration status and water intake. METHODS: This study involved 8 visits to the Human Performance Laboratory over 22 days. Body …

Design of the aerobic hail reactor - towards improved energy efficiency
This dissertation presents the results of an investigation into the design of a novel low aspect ratio reactor, dubbed the HAIL (horizontal air-injected loop) reactor. Current industrial high cell density aerobic reactors for cultivation of bacteria and yeast are typically either stirred tank …

Asymptotics of Carleman Polynomials for Level Curves of the Inverse of a Shifted Joukowsky Transformation
Let L be a level curve of the inverse of the shifted Joukowsky transformation w [special characters omitted] w − 1 + (w − 1) –1, that is, [special characters omitted]In this thesis we investigate the asymptotic properties of the sequence of polynomials that are orthonormal over the interior domain …

Generalized Group Presentations and Formal Deformations of Cw Complexes
A Peiffer-Whitehead word system W, or generalized group presentation, consists of generators for a free group and words of various orders n (GREATERTHEQ) 2 representing elements of the free group (n = 2), a free crossed module (n = 3) or a free module (n > 3). The P(,n)-equivalence relation on word …

Evaluation of hydrothermal pretreatment and fermentation to improve lipid and ethanol production from corn germ meal
Vegetable oil is extracted from oil rich seeds, such as soybeans. Genetic engineering of plants to accumulate oil in vegetative tissue is a potential future source of vegetable oil that promises increased land productivity and use of marginal lands. However, low concentrations of lipids in current …

Comparison of Speech Audiometry Stimulus Lists on Hearing Impaired and Normal Hearing Subjects
The appropriateness and differences of different speech recognition and speech intelligibility word lists were investigated. It has been reported that the use of two-syllable spondee words that are comprised of high frequency sounds may more accurately represent the true speech recognition …

Impact of silicon nitride thickness on the infrared sensitivity of silicon nitride-aluminum microcantilevers
This thesis investigates how silicon nitride thickness impacts the performance of silicon nitride - aluminum bimaterial cantilever infrared sensors. A model predicts cantilever behavior by considering heat transfer within and from the cantilever, cantilever optical properties, cantilever bending …

Parameterized Algorithmics for Network Analysis
Diese Arbeit beschäftigt sich mit der parametrisierten Komplexität NP-schwerer Berechnungsprobleme aus zwei Bereichen der Netzwerkanalyse: dem Clustern von Netzwerken und dem Querying von Netzwerken. Der Fokus liegt hierbei auf der Identifizierung neuer problemspezifischer Parameter, welche als …

Continuity Properties and Variational Problems Involving the Determinant of the Hessian
This thesis investigates continuity properties of the distributional determinant of the Hessian of a scalar function u in various function spaces. It is well known that when D is a bounded, open subset of n-dimensional Euclidean space Rn, the distributional determinant of the Hessian is weakly …

Exponential Decay for the Saint-Venant Principle
We consider a semi-infinite beam B = {(z,t)(VBAR)z(ELEM)(OMEGA), t (GREATERTHEQ) 0} where (OMEGA) is a bounded domain in (//R)('2) with the cone property and a C('3)-smooth boundary. By applying semigroup theory and spectral theory, we show that in our formulation Saint-Venant's principle is true …

Computational Bayesian techniques applied to cosmology
This thesis presents work around 3 themes: dark energy, gravitational waves and Bayesian inference. Both dark energy and gravitational wave physics are not yet well constrained. They present interesting challenges for Bayesian inference, which attempts to quantify our knowledge of the universe …

Concept and feasibility study of self-organized electrochemical devices
Since Volta's discovery of " an electric battery" in 1800, advancements have proceeded due to great materials advances. However, the basic configuration he proposed then is still present in today's portable power sources. In this work, using attractive and repulsive London-van der Waals forces, a …

Mappings Between Annuli of Smallest p-Harmonic Energy
<p>An important topic in the calculus of variations is the study of traction-free problems, in which deformations between given domains in $\mathbb{R}^n$ are allowed to slip on the boundary, without prescribing boundary values. For annuli $\A = \A(r, R)$ and $\A^* = \A(r_*, R_*)$, we seek the …

Synthesis of zeolites and their application as soil amendments to increase crop yield and potentially act as controlled release fertilizers.
Zeolites have been used in agriculture since the 1960s, due to the effectiveness of these crystalline microporous solids as soil amendments for plant growth, their cation exchange capacity (CEC) and slow-release fertilizer properties. Most work on slow-release fertilizers has focused on natural …

Gas exchange kinetics in elite runners.
Oxygen uptake (VO[2]) kinetics measured in the frequency domain are known to be faster in subjects of greater aerobic fitness (Essfeld et al. 1987). Carbon dioxide output (VCO[2] ) kinetics have been shown to be delayed following 6 months sprint and strength training in footballers (Fukuoka et al …

A study of the lines of flow and the equipotential lines in a plate conductor
1. The function z = w + k√(w² - 1) will represent in the z plane the lines of flow of an electric current in a plate conductor around a circle of unit radius if the constant k is unity and around an ellipse of the form x²/1 + y²/k² = 1 which is oblate if the constant k is greater than unity and …

Algorithms and lower bounds for sparse recovery
We consider the following k-sparse recovery problem: design a distribution of m x n matrix A, such that for any signal x, given Ax with high probability we can efficiently recover x satisfying IIx - x l, </-Cmink-sparse x' IIx - x'II. It is known that there exist such distributions with m = O(k …

Red-blue and standard pebble games : complexity and applications in the sequential and parallel models
Pebble games are games played on directed acyclic graphs involving placing and moving pebbles on nodes of the graph according to a certain set of rules. The standard pebble game (also known as the black pebble game) is the first of such games played on DAGs. The game itself involves three simple …

The Role Of Traditionalism In Patterns Of Support From Adult Children To Fathers In The Later Years
<p>This study explores the effects of fathers' gender role attitudes on the receipt of instrumental and expressive support from their adult children. Using data on 1159 fathers aged 50-94 from the National Survey of Families and Households (W-1), I sought to determine if fathers' traditional gender …
