Mathematical Analysis For The Hydrodynamic Model Of Semiconductors., Chen Zhu
Mathematical Analysis For The Hydrodynamic Model Of Semiconductors., Chen Zhu
Graduate Theses, Dissertations, and Problem Reports (ETD)
In this thesis we study two cases of the hydrodynamic model of semiconductors: the nonisentropic case for one species and the isentropic case for two species. The purpose of this thesis is to discuss the asymptotic stability of the steady state solutions for these two cases. First we show the existence of a one-parameter family of steady state solutions. Each steady state solution is uniquely determined by the momentum. Then, we prove that every steady state solution is asymptotically stable. Namely, if the initial data is "close" to a given steady state solution, then the dynamic solution will asymptotically approaches …
Limiting Spheroid Size As A Function Of Growth Factor Source Location, J. A. Adam, K. Y. Ward
Limiting Spheroid Size As A Function Of Growth Factor Source Location, J. A. Adam, K. Y. Ward
Mathematics & Statistics Faculty Publications
Solutions C(r) of the time-independent nonhomogeneous diffusion equation for three different piecewise-uniform source terms are used to examine the limiting size of multicell spheroids using a simple model which reproduces concentration-dependent mitotic behavior. A condition is derived under which nontrivial solutions do not exist (in all three cases), and a condition for the existence of a unique nontrivial solution is established for the case of growth-modifying factor (GMF) production throughout the spheroid. Qualitative behavior of the limiting size is established as a function of various physiological parameters. Of fundamental importance is the assumed GMF concentration threshold θ, …

Scattering From Stellar Acoustic-Gravity Potentials: Ii. Phase Shifts Via The First Born Approximation, J. A. Adam, I. Mckaig
Mathematics & Statistics Faculty Publications
Using the first Born approximation, properties of the scattering phase shift are investigated for waves that are scattered by a schematic representation of a large-scale “stellar potential,” i.e., one for which the star itself is viewed as the potential inducing a phase shift in an incoming wave. In particular, the phase shift properties are examined as functions of the relative wavenumber (α) and the azimuthal wavenumber (l), high l-values being of interest in helioseismology.
Continuities Of Metric Projection And Geometric Consequences, Robert Huotari, Wu Li
Continuities Of Metric Projection And Geometric Consequences, Robert Huotari, Wu Li
Mathematics & Statistics Faculty Publications
We discuss the geometric characterization of a subset K of a normed linear space via continuity conditions on the metricprojection onto K. The geometric properties considered includeconvexity, tubularity, and polyhedral structure. The continuityconditions utilized include semicontinuity, generalized stronguniqueness and the non-triviality of the derived mapping. Infinite-dimensional space with the uniform norm we show thatconvexity is equivalent to rotation-invariant almost convexityand we characterize those sets every rotation of which has continuousmetric projection. We show that polyhedral structure underliesgeneralized strong uniqueness of the metric projection.
Antiplane Shear Of A Strip Containing A Staggered Array Of Rigid Line Inclusions, G. Kerr, G. Melrose, J. Tweed
Antiplane Shear Of A Strip Containing A Staggered Array Of Rigid Line Inclusions, G. Kerr, G. Melrose, J. Tweed
Mathematics & Statistics Faculty Publications
Motivated by the increased use of fibre-reinforced materials, we illustrate how the effective elastic modulus of an isotropic and homogeneous material can be increased by the insertion of rigid inclusions. Specifically we consider the two-dimensional antiplane shear problem for a strip of material. The strip is reinforced by introducing two sets of ribbon-like, rigid inclusions perpendicular to the faces of the strip. The strip is then subjected to a prescribed uniform displacement difference between its faces, see Figure 1. it should be noted that the problem posed is equivalent to that of the uniform antiplane shear problem for an infinite …

The Ability Of Children With Specific Language Impairment To Participate In A Group Decision Task, Lee Robinson, Martin Fujiki, Bonnie Brinton, Valyne J. Watson
Faculty Publications
This study examined the ability of 6 children with specific language impairment (SLI), ages 8:10 to 12:5 (years; months), to participate in a group negotiation task. Each child interacted with two peers to select toys that children their age would enjoy. Performance was compared to both chronological age-similar (CS) peers and language similar (LS) peers performing the same task. Analyses of the resulting interactions indicated that subjects with SLI produced significantly fewer utterances than the other children in the triad. Similar differences were not observed in the CS or LS triads. Additionally, significantly fewer utterances were addressed to the children …
Determination Of Asphaltenes In Petroleum Crude Oils By Fourier Transform Infrared Spectroscopy, Brian K. Wilt
Determination Of Asphaltenes In Petroleum Crude Oils By Fourier Transform Infrared Spectroscopy, Brian K. Wilt
Theses, Dissertations and Capstones
An analytical method was developed to quantitatively determine the asphaltene content in petroleum crude oils by Fourier transform infrared spectroscopy (FT-IR). Asphaltenes are a solubility class of compounds found in crude oils. They are black to dark brown solids defined by their insolubility in n-alkane solvents. The structure of asphaltene molecules is polynuclear aromatic rings with alkyl side chains and heteroatoms, such as nitrogen, oxygen, and sulfur attached. Asphaltenes are known to cause oil well plugging and irreversible catalyst deactivation in refineries. The asphaltene content of 50 crude oils from a wide array of geochemical conditions was determined by the …

A Parametric Study Of Knock Control Strategies For A Bi-Fuel Engine., William Scott Wayne
Graduate Theses, Dissertations, and Problem Reports (ETD)
A numerical thermodynamic model was developed and employed to investigate the use of elevated compression ratios, variable valve timing, and ignition timing modulation as a means of controlling knock and improving the performance of a bi-fuel engine. The proposed strategy employed an increased compression ratio to boost power and torque when operating on natural gas. An increased intake duration and retarded ignition timing were then employed to control knock during gasoline operation. Dynamometer testing was performed on a 1.9 liter Saturn{dollar}\\sp\\circler{dollar} engine to provide empirical data for model calibration and to evaluate the effects of proposed changes on engine emissions. …
Crime And The Nation: Prison Reform And Popular Fiction In Philadelphia, 1786-1800., Peter Thomas Okun
Crime And The Nation: Prison Reform And Popular Fiction In Philadelphia, 1786-1800., Peter Thomas Okun
Graduate Theses, Dissertations, and Problem Reports (ETD)
The prison reformers and fiction writers of post-Revolutionary Philadelphia wrote prodigiously about crime and punishment. In a correlative study, I explore juridical topoi in reformist and fictive texts familiar to republican Philadelphians. My analysis assumes a public sphere of writers and readers: while late eighteenth-century prison reforms and fictions came out of separate signifying systems, there was considerable promiscuity between them. I group areas of overlap around cultural concerns (science, murder, sex) and representational "spaces" (home, prison, nation). In either discourse, crime and punishment were useful to a post-Revolutionary aesthetic of nationalism. The scientific rhetoric of penitentiary punishment targeted the …
Performance-Tunable Distributed Execution Of Object-Based Software., George Braden Rinard
Performance-Tunable Distributed Execution Of Object-Based Software., George Braden Rinard
Graduate Theses, Dissertations, and Problem Reports (ETD)
The central challenge in software engineering research and practice is to improve the quality and performance of software systems, while decreasing the cost for producing such systems. While the combination of parallel execution with component-based software construction provides opportunities for addressing the software development challenge, it also raises a fundamental distributed software engineering dilemma, not adequately addressed in the literature. This dilemma is a result of the following two observations: (1) The quality and productivity benefits of reusability accrue only when reusable components are used without modifications. (2) For improved performance in a distributed environment, it must be possible to …

Postsecondary Persistence Of Ged Students., Maria C. Rose
Graduate Theses, Dissertations, and Problem Reports (ETD)
More nontraditional students are attending college, and many of these students are enrolled with GED certification. The validity using GED certification as postsecondary admission criteria has been questioned. Participants included 251 students enrolled with GED certification as admission criteria to a small Mid-Atlantic college in the Spring 1997 semester. The influence of ACT, GED, literacy scores, learning and study skills, and the number of successfully completed developmental classes on grade point averages was researched. Students were interviewed to gain insight into students' perceptions of factors contributing to persistence in college. ACT scores were found to be good predictors of grade …
Robust Design Optimization With Applications To Composite-Material Structures., Satheesh Makkapati
Robust Design Optimization With Applications To Composite-Material Structures., Satheesh Makkapati
Graduate Theses, Dissertations, and Problem Reports (ETD)
The problem of robust design and optimization for designs with varying operating conditions is considered in this work. A robust design optimization tool (RDOT) has been developed in this work. The tool is constructed with building blocks: an Artificial Neural Network, a Response Evaluator (e.g., FEA, etc.), an Optimizer based on Quadratic Programming, Cooperative Game Theory, Design of Experiments, and Taguchi Methods. The tool is fully codified into a computer program, and it demands very little designer insight into the problem under consideration. Design optimization is necessary to efficiently accomplish a design that, while satisfying the desired functionality, also uses …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Since the advent of computers, scientists have tried to use the human languages for communication with computers. This pursuit has led several scientists, such as Chomsky to establish that there must be a specific part of the brain adapted to language learning and processing genetically, namely the "language organ". Humans are able to understand and produce sentences that they may have never heard. This leads to the understanding that language must follow some strict rules of processing which is referred to as "grammar of a language". The Artificial Neural Networks (NN) inspired by the neural networks of biological systems have …

Comparison Of A Pin Cam And An Inverted Pin Cam Design Based On The Parameters Used For The Axial Vane Rotary Engine (Beta Version)., Phillip Howard Burnside
Comparison Of A Pin Cam And An Inverted Pin Cam Design Based On The Parameters Used For The Axial Vane Rotary Engine (Beta Version)., Phillip Howard Burnside
Graduate Theses, Dissertations, and Problem Reports (ETD)
The comparison of two design variations of the Axial Vane Rotary Engine (AVRE) was done by evaluating several parameters. These two designs are called the Pin Cam and the Inverted Pin Cam designs. The first step involved developing a technique to determine the heat loads on the components of the engines since the engine is running at a steady state loading condition. The second step used this thermal data to get a final temperature profile. The third step combined the thermal data and the combustion data to perform a structural analysis of the engine components. This illustrated both the stresses …
Faculty Stance Toward Multiculturalism And Multicultural Education: A Qualitative Study., Jane Sheridan Cardi
Faculty Stance Toward Multiculturalism And Multicultural Education: A Qualitative Study., Jane Sheridan Cardi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Studies indicate that the implementation of multiculturalism into university general education course requirements such as introductory American literature is sporadic. Furthermore, although research suggests that faculty are more frequently including multicultural literature in their courses, there is little research concerning what faculty believe about multiculturalism and multicultural education and how faculty actually teach multiculturalism in higher education. The purpose of this study is to contribute to the knowledge of why faculty do or do not implement multiculturalism into their curricula and if they do, how they implement it. This study uses phenomenological and hermeneutic research methods to explore the stances, …

A Comparative Study Of The Development Of Educational Psychology In China And America., Huiping Liu Cervenka
Graduate Theses, Dissertations, and Problem Reports (ETD)
Some people argue that Western psychology and Asian psychology are fundamentally different and irreconcilable. Western psychology is scientific and analytic-reductionistic, while Asian psychology is concerned with man's harmony{dollar}\\...{dollar} (in Paranjpe et al, 1988, p18). This study examines and compares the scientific roots of Western psychology and the humanistic roots of Asian psychology in an attempt to determine commonality between Chinese and American educational psychology. A historical comparative method is used in this study. Two approaches, the personalistic and the naturalistic are employed to examine the development of educational psychology in China and America. Results show that Western psychology has been …

There Was Something In The Water: Parallels In Paradigms In English And Physics, 1880 To 1940., Tracy Joan Demars
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study posits that a paradigm is a shared vision of reality that governs how practitioners define and relate to the many and varied components that make up that reality. Using this definition, the author presents a visual model using concentric spheres of increasing abstraction that rearrange T. S. Kuhn's four components of a disciplinary matrix that he articulated in the 1969 Postscript to The Structure of Scientific Revolutions. Based on this model and D'Amico's criteria for a coherent narrative, the study assesses the two primary paradigms, labeled the Object-Oriented paradigm and the Subject-Oriented paradigm, that existed in the fields …
