Lipschitz Continuity Of The Best Approximation Operator In Vector-Valued Chebyshev Approximation, Martin Bartelt, John Swetits Jan 2008

Lipschitz Continuity Of The Best Approximation Operator In Vector-Valued Chebyshev Approximation, Martin Bartelt, John Swetits

Mathematics & Statistics Faculty Publications

When G is a finite dimensional Haar subspace of C(X, Rk), the vector-valued continuous functions (including complex-valued functions when k is 2) from a finite set X to Euclidean k-dimensional space, it is well-known that at any function f in C(X, Rk) the best approximation operator satisfies the strong unicity condition of order 2 and a Lipschitz (H˝older) condition of order 1/2. This note shows that in fact the best approximation operator satisfies the usual Lipschitz condition of order 1.

Analytical Solution To The Wave Equation With Discrete Pressure Sources: A Model For The Rijke Tube, Eduardo G. Perez Jan 2008

Analytical Solution To The Wave Equation With Discrete Pressure Sources: A Model For The Rijke Tube, Eduardo G. Perez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite of having been studied for several decades the phenomena of combustion instabilities are not well understood. Pressure waves due to the combustion instabilities can become violent being detrimental for both the performance and combustor life. A good prediction of the pressure distribution inside the combustor is important in order to prevent theoccurrence of this phenomenon. In this work a technique for solving the wave equation with discrete sources (or sinks) using the Green's functions was developed. One and two-dimensional approaches for cylindrical and Cartesian coordinates withconstant speed of sound were solved. Also the case of one-dimensional axially varying temperature …

A New Era Of Federal Sentencing: The Guidelines Provide District Court Judges A Cloak, But Is Gall Their Dagger?, Anna E. Papa Jan 2008

A New Era Of Federal Sentencing: The Guidelines Provide District Court Judges A Cloak, But Is Gall Their Dagger?, Anna E. Papa

Georgia Law Review

Federal district court judges today have a level of sentencing discretion that has been unknown since the adoption of the United States Sentencing Guidelines. This Note reviews the history of the Guidelines and outlines the problems that have resulted from the Supreme Court's decisions in Booker, Rita, and Gall This Note argues that the confusion may be clarified by giving effect to the text of 18 U.S.C. §3553(a), which requires that federal district court judges impose sentences that are sufficient, but not greater than necessary, and requires them to examine all the factors provided in the statute. The court's recent …

The β-Tubulin Gene As A Means To Discriminate Species And Verify Evolutionary Patterns Of Arbuscular Mycorrhizal Fungi., Zola Msiska Jan 2008

The β-Tubulin Gene As A Means To Discriminate Species And Verify Evolutionary Patterns Of Arbuscular Mycorrhizal Fungi., Zola Msiska

Graduate Theses, Dissertations, and Problem Reports (ETD)

Arbuscular mycorrhizal fungi (AMF) associating with 80% of vascular plant families increase uptake of nutrients and water in plants, help to stabilize soil aggregates and improve soil aeration, water percolation and carbon storage. Phylogeny of AMF based on rDNA sequences is in conflict with morphology-based phylogeny. The aim of the present study was to examine a protein encoding gene, β-tubulin, in order to test conclusions drawn from rDNA sequences and morphological data. Inverse-PCR was used to amplify full-length β-tubulin genes of Gigaspora gigantea and Glomus clarum. The gene in both species is organized into five exons and four introns encoding …

Is Congruence Dead? An Examination Of The Correlation Between Holland's Congruence And Job Satisfaction Using Improved Methodology., Shannon Marie Bowles Jan 2008

Is Congruence Dead? An Examination Of The Correlation Between Holland's Congruence And Job Satisfaction Using Improved Methodology., Shannon Marie Bowles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Job satisfaction is considered to be the most important and frequently examined outcome variable in congruence research. The assumption that congruence results in job satisfaction is fundamental to Holland's theory; however, the empirical evidence predominantly indicates that the congruence - job satisfaction correlation is, at best, equivocal. There is a movement within vocational psychology that the congruence construct is “dead” as a viable theoretical concept and that the field should abandon Holland's theory. This idea does not exist without significant argument, however. It has been recognized widely that congruence has not fared better in the empirical research literature because methodological …

Back To The Beginning: An Essay On The Court, The Law Of Democracy, And Trust, Luis Fuentes-Rohwer Jan 2008

Back To The Beginning: An Essay On The Court, The Law Of Democracy, And Trust, Luis Fuentes-Rohwer

Articles by Maurer Faculty

The law of democracy is in a state of incoherence. The experiment begun by Baker v. Carr showed great promise yet soon gave way to disappointment. The promise was one of modest review and respect for political choices made elsewhere. A presumption was still against judicial involvement: absent self-entrenchment or distrust of political outcomes, the Court would stay its hand. But, the reality has been far from that. The presumption has now clearly shifted, and the Court intervenes in politically-charged controversies as a matter of course. This raises a question at the heart of the law of democracy: can we …

Socially Rational Models For Autonomous Agents, Wynn C. Stirling, James K. Archibald, Matthew S. Nokleby Jan 2008

Socially Rational Models For Autonomous Agents, Wynn C. Stirling, James K. Archibald, Matthew S. Nokleby

Faculty Publications

Autonomous multi-agent systems that are to coordinate must be designed according to models that accommodate such complex social behavior as compromise, negotiation, and altruism. In contrast to individually rational models, where each agent seeks to maximize its own welfare without regard for others, socially rational agents have interests beyond themselves. Such models require a new type of utility function a social utility to ensure three desirable properties: (a) conditional preferences agents may adjust their preferences to account for the preferences of others; (b) endogeny group preferences are determined internally by interactions between individual agents; (c) framing invariance reformulations of the …

Response Rate Or Number Of Repetitions: Which Aspect Of Drill And Practice Testing Most Contributes To Paired-Associate Learning., Scott Davis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Precision teaching methods began in the 1960s and have grown in utility and popularity over the last four decades (Downer, 2007). The methods are used to teach across multiple contents with an emphasis in achieving fluency as opposed to mere accuracy. Speed drills, frequently used to determine the learner's current level of fluency, were found to have a significant treatment effect on learning (McGreevy, 1978; Scott, Wolking, Stoutimore, & Harris, 1990; White & Haring, 1976). The purpose of this study is to isolate and measure the treatment effect of two key aspects of the speed drill and practice component of …

Instructors And Their Students: The Relationship Between Out -Of -Class Communication, Student Communication Motives, Student Motivation, And Instructor Job Satisfaction And Motivation., Jennifer L. Knapp

Graduate Theses, Dissertations, and Problem Reports (ETD)

The bulk of instructional communication research is concerned with the impact of instructors on students, leaving very few studies that focus on the affects of students on instructors. The purpose of this study, therefore, was to identify the impact students have on instructor out-of-class communication (OCC), job satisfaction, and motivation. Student relational, functional, participatory, excuse-making and sycophancy motives for communicating, along with perceived student motivation were examined in order to learn more about the influence of students on instructors. Participants (college instructors, N = 268) completed an online questionnaire about their OCC, job satisfaction, and motivation, as well as perceived …

Reduced Order Modeling Of Time-Dependent Reflectance Profiles From Purely Scattering Media, R. Scott Larson, Matthew R. Jones Jan 2008

Reduced Order Modeling Of Time-Dependent Reflectance Profiles From Purely Scattering Media, R. Scott Larson, Matthew R. Jones

Faculty Publications

Due to the widespread existence and importance of foam, inverse techniques for characterizing industrial foams are of interest. An essential element in an inverse method used to characterize a foam layer is a model of the time-dependent reflectance of a laser pulse. Monte Carlo methods may be used to accurately model reflectance, but these methods are computationally expensive. Computationally efficient methods based on the diffusion approximation have been developed, but this approach is not sufficiently accurate in many cases of interest. Therefore, a computationally efficient and robust method is desirable. This paper presents a computationally efficient method for modeling the …

A Growth-Theoretic Empirical Analysis Of Simultaneity In Cross-National E-Commerce Development, Shu-Chun Ho, Robert J. Kauffman, Ting-Peng Liang Jan 2008

A Growth-Theoretic Empirical Analysis Of Simultaneity In Cross-National E-Commerce Development, Shu-Chun Ho, Robert J. Kauffman, Ting-Peng Liang

Research Collection School Of Computing and Information Systems

The emergence of information and communication technologies infrastructure has transformed the global economy. The development of information technology infrastructure is limited to some developed countries though. This research explores the role of information technology infrastructure in B2C e-commerce growth at the country-level from the perspective of growth theory in economics. We propose a hybrid exogenous and endogenous growth model to explain e-commerce growth. We estimate a panel data model that incorporates the direct effects of e-commerce infrastructure and other key explanatory variables. We further specify a simultaneous effects model that permits the analysis of reverse causality in the association between …

Face Annotation Using Transductive Kernel Fisher Discriminant, Jianke Zhu, Steven C. H. Hoi, Michael R. Lyu Jan 2008

Face Annotation Using Transductive Kernel Fisher Discriminant, Jianke Zhu, Steven C. H. Hoi, Michael R. Lyu

Research Collection School Of Computing and Information Systems

Face annotation in images and videos enjoys many potential applications in multimedia information retrieval. Face annotation usually requires many training data labeled by hand in order to build effective classifiers. This is particularly challenging when annotating faces on large-scale collections of media data, in which huge labeling efforts would be very expensive. As a result, traditional supervised face annotation methods often suffer from insufficient training data. To attack this challenge, in this paper, we propose a novel Transductive Kernel Fisher Discriminant (TKFD) scheme for face annotation, which outperforms traditional supervised annotation methods with few training data. The main idea of …

Dividend Behaviour Of Nyse-Listed Banks Within An Optimal Control Theory Framework, Rumbi Mukonoweshuro Jan 2008

Dividend Behaviour Of Nyse-Listed Banks Within An Optimal Control Theory Framework, Rumbi Mukonoweshuro

Plymouth Business School Theses

Within the dividend policy literature there is no universally accepted model to explain dividend behaviour. The theoretical dividend policy literature contains a promising dynamic mathematical model based on optimal control theory formulated by Davidson (1980), in the spirit of the Modigliani-Brumberg-Yaari types of lifecyle hypothesis, but despite being published some time ago the model has not been tested empirically, possibly due to its complexity. It is the main purpose of this research study to investigate the dividend behaviour patterns of banks listed on the NYSE within this optimal control theory framework. This work unfolds in three stages as follows: initially …

Implementation Of Medical Imaging With Telemedicine For The Early Detection And Diagnoses Of Breast Cancer To Women In Remote Areas, Alphonsine Imaniraguha

Theses

Nowadays, the cancer topic has become a global concern. Furthermore, breast cancer persists to be the top leading cause of death to women population and the second cause of cancer death after the lung cancer globally. Various technologies and techniques have been searched, developed and studied over the years to detect the disease at the early stage; the early diagnosis saves many lives in both developed and developing countries. The detection of cancer through a screening process before its symptoms emerge increases the survival rate dramatically (Li, Meaney and Paulsen). Moreover, sufficient knowledge of the disease, qualified staff, accurate, appropriate …

Counting Points On Elliptic Curves Over Zp, Suresh Sundriyal Jan 2008

Counting Points On Elliptic Curves Over Zp, Suresh Sundriyal

Theses

The mathematics of elliptic curves has been studied since ancient times. These mathematical structures have found applications in varied fields. More recently, there has been a growing interest in applying these structures to cryptography. Various such applications have been proposed. Elliptic curve based cryptographic algorithms have been shown to provide greater security with shorter key sizes than the conventional RSA based cryptosystems, making them more memory e cient and less processor intensive. One of the fundamental requirements of all such elliptic curve cryptographic algorithms is that the order of the group of points satisfying the elliptic curve meet a certain …

Elliptic Curve Cryptography: Generation And Validation Of Domain Parameters In Binary Galois Fields, Peter Wozny Jan 2008

Elliptic Curve Cryptography: Generation And Validation Of Domain Parameters In Binary Galois Fields, Peter Wozny

Theses

Elliptic curve cryptography (ECC) is an increasingly popular method for securing many forms of data and communication via public key encryption. The algorithm utilizes key parameters, referred to as the domain parameters. These parameters must adhere to specific characteristics in order to be valid for use in the algorithm. The American National Standards Institute (ANSI), in ANSI X9.62, provides the process for generating and validating these parameters. The National Institute of Standards and Technology (NIST) has identified fifteen sets of parameters; five for prime fields, five for binary fields, and five for Koblitz curves. The parameter generation and validation processes …

Rates Of Carbonate Dissolution In Permeable Sediments Estimated From Porewater Profiles: The Role Of Sea Grasses, David J. Burdige, Richard C. Zimmerman, Xinping Hu Jan 2008

Rates Of Carbonate Dissolution In Permeable Sediments Estimated From Porewater Profiles: The Role Of Sea Grasses, David J. Burdige, Richard C. Zimmerman, Xinping Hu

OES Faculty Publications

In this study we estimate sediment carbonate dissolution rates for sandy sea grass sediments on the Bahamas Bank using an inverse pore-water advection/diffusion/reaction model constrained by field observations. This model accounts for sea grass O2 input to these sediments, and also parameterizes pore-water advection through these permeable sediments as a nonlocal exchange process. The resulting rates of carbonate dissolution are positively correlated with sea grass density, and are comparable with previous rate estimates for Florida Bay sediments. In contrast, the advective uptake of O2 by these sediments decreased with increasing sea grass density. This suggests that the competing …

Radiocarbon Evidence For The Importance Of Surface Vegetation On Fermentation And Methanogenesis In Contrasting Types Of Boreal Peatlands, J. P. Chanton, P. H. Glaser, L. S. Chasar, David J. Burdige, M. E. Hines, D. I. Seigel, L. B. Tremblay, W. T. Cooper

OES Faculty Publications

We found a consistent distribution pattern for radiocarbon in dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and methane replicated across spatial and temporal scales in northern peatlands from Minnesota to Alaska. The 14C content of DOC is relatively modern throughout the peat column, to depths of 3 m. In sedge-dominated peatlands, the 14C contents of the products of respiration, CH4 and DIC, are essentially the same and are similar to that of DOC. In Sphagnum- and woody plant-dominated peatlands with few sedges, however, the respiration products are similar but intermediate between the 14C contents of …

Co2 Sensitivity Of Southern Ocean Phytoplankton, Philippe D. Tortell, Christopher D. Payne, Yingyu Li, Scarlett Trimborn, Bjorn Rost, Walker O. Smith, Christina Riesselman, Robert B. Dunbar, Peter Sedwick, Giacomo R. Ditullio Jan 2008

Co2 Sensitivity Of Southern Ocean Phytoplankton, Philippe D. Tortell, Christopher D. Payne, Yingyu Li, Scarlett Trimborn, Bjorn Rost, Walker O. Smith, Christina Riesselman, Robert B. Dunbar, Peter Sedwick, Giacomo R. Ditullio

OES Faculty Publications

The Southern Ocean exerts a strong impact on marine biogeochemical cycles and global air-sea CO2 fluxes. Over the coming century, large increases in surface ocean CO2 levels, combined with increased upper water column temps. and stratification, are expected to diminish Southern Ocean CO2 uptake. These effects could be significantly modulated by concomitant CO2-dependent changes in the region's biol. carbon pump. Here we show that CO2 concentrations affect the physiology, growth and species composition. of phytoplankton assemblages in the Ross Sea, Antarctica. Field results from in situ sampling and ship-board incubation experiments demonstrate that inorganic …

Multiple Channel Coherent Amplitude Modulated (Am) Time Division Multiplexing (Tdm) Software Defined Radio (Sdr) Receiver, Veerendra Bhargav Alluri

University of Kentucky Master's Theses

It is often required in communication and navigation systems to be able to receive signals from multiple stations simultaneously. A common practice to do this is to use multiple hardware resources; a different set of resources for each station. In this thesis, a Coherent Amplitude Modulated (AM) receiver system was developed based on Software Defined Radio (SDR) technology enabling reception of multiple signals using hardware resources needed only for one station. The receiver system architecture employs Time Division Multiplexing (TDM) to share the single hardware resource among multiple streams of data. The architecture is designed so that it can be …
