An Empirical Study Of Instance Hardness, Michael Reed Smith

Theses and Dissertations

Most widely accepted measures of performance for learning algorithms, such as accuracy and area under the ROC curve, provide information about behavior at the data set level. They say nothing about which instances are misclassified, whether two learning algorithms with the same classification accuracy on a data set misclassify the same instances, or whether there are instances misclassified by all learning algorithms. These questions about behavior at the instance level motivate our empirical analysis of instance hardness, a measure of expected classification accuracy for an instance. We analyze the classification of 57 data sets using 9 learning algorithms. Of …

Random Graphs: From Paul Erdős To The Internet, Michał Karoński

Dalrymple Lecture Series

Paul Erdős, one of the greatest mathematicians of the twentieth century, was a champion of applications of probabilistic methods in many areas of mathematics, such as a graph theory, combinatorics and number theory. He also, almost fifty years ago, jointly with another great Hungarian mathematician Alfred Rényi, laid out foundation of the theory of random graphs: the theory which studies how large and complex systems evolve when randomness of the relations between their elements is incurred. In my talk I will sketch the long journey of this theory from the pioneering Erdős era to modern attempts to model properties of …

Design Of Soa Based Web Service Systems Using Qfd For Satisfaction Of Quality Of Service Requirements, Xiaoqing Frank Liu, Lianzhang Zhu

Computer Science Faculty Research & Creative Works

Service-Oriented Architecture (SOA) is a loosely coupled architecture designed to meet business needs of an organization. It is becoming a trend for system development and integration where systems group functionality around business processes. Although SOA does not require Web services, Web services are based on accepted standards and drive SOA to the mainstream. There are at least two challenges with quality management of SOA based Web service systems. One of them is how to link explicitly its technical capability with customers' needs to satisfy customers' functional and nonfunctional requirements. the second is how to determine targets of Web service technical …

An Online Credential Repository For Role-Based Delegation, Guangxu Zhou Zhou

Theses and Dissertations

In large scaled organizations deployed with Role-based Access Control, it is desired to have role delegation services within the domain of the corporation. But there is no widely accepted delegation model yet due to the complicated properties of authorization. The delegation model needs to bridge resources, policies, owners and users perfectly which demands more dimensions to be managed than the authentication process conducts. In this research work, we are proposing a prototype that enables delegation service for group users communicating with multicasting channels, the Role-based Access Control applied for both the communications and the user credentials of authorization. We combined …

Growth And Geodesics Of Thompson's Group F, Jennifer L. Schofield

Theses and Dissertations

In this paper our goal is to describe how to find the growth of Thompson's group F with generators a and b. Also, by studying elements through pipe systems, we describe how adding a third generator c affects geodesic length. We model the growth of Thompson's group F by producing a grammar for reduced pairs of trees based on Blake Fordham's tree structure. Then we change this grammar into a system of equations that describes the growth of Thompson's group F and simplify. To complete our second goal, we present and discuss a computer program that has led to some …

Synthesis And Evaluation Of N6,5'-Bis-Ureido-5'-Amino-5'-Deoxyadenosine Derivatives: Novel Nucleosides With Antiproliferative And Protein Kinase Binding Activities, Marcelio Oliveira

Theses and Dissertations

A new series of N6,5'-bis-ureido-5'-amino-5'-deoxyadenosine derivatives was prepared and evaluated for anticancer activities using the NCI 60 panel of human cancers. Certain of the derivatives showed promising activities (low micromolar GI50's) against several of the representative cancers. These included cell lines from the following general cell types in the NCI 60: Leukemia, Breast, Central Nervous System, Non-Small Cell Lung, Ovarian, Prostate, Renal, and Colon cancers. Select compounds were also screened for their affinities for protein kinases. The synthesis of the compounds was straightforward and involved N6 acylation with arylisocyanates, preceded by activation and nucleophilic substitution of the 5'-position to give …

Dark Matter Halos And Evolution Of Bars In Disk Galaxies: Collisionless Models Revisited, Jorge Villa-Vargas, Isaac Shlosman, Clayton Heller

Physics & Astronomy: Faculty Publications

We construct and evolve three one-parameter families and one two-parameter family of steady-state models of stellar disks embedded in live dark matter (DM) halos in order to study the dynamical and secular phases of bar evolution. These models are tested against those published in the literature in order to extend them and to include the gaseous component in the follow-up paper. Specifically, we are interested in the angular momentum, J, redistribution in the disk-halo system during these two evolutionary phases without distinguishing between the resonant and non-resonant effects. We confirm the previous results and quantify for the first time …

The Riemann Hypothesis…, Micah Milinovich

Algebra/Number Theory Seminar

The Riemann Hypothesis is 150 years old. In the fall of 1859, G. F. B. Riemann communicated his now famous paper “Ueber die Anzahl der Primzahlen unter einer gegebenen Grösse" - translated as ”On the number of primes less than a given magnitude" to the Berlin Academy. In this paper, he outlined a potential proof of what is now called the Prime Number Theorem. His idea was to explicitly relate sums over the zeros of a certain meromorphic function (now called the Riemann zeta-function) to sums over the prime numbers. He further conjectured that all the zeros of this function …

Metal-Insulator-Insulator-Metal Plasmonic Waveguides And Devices, Jing Chen

Electrical and Computer Engineering ETDs

Metal-insulator-metal (MIM) plasmonic waveguides have been proposed for highly integrated subwavelength structures. In this work, waveguiding and coupling of surface plasmon polaritons (SPPs) within finite planar MIM plasmonic waveguides are examined both theoretically and experimentally. Gain (dye-doped polymer)-assisted MIM waveguides and terahertz quantum cascade laser MIM waveguides are numerically analyzed. The numerical analysis of finite planar MIM waveguides using the transfer matrix formalism reveals both bound and leaky SP modes: three lowest energy bound modes and the highest energy mode consisting of non-radiative (bound) and radiative (leaky) portions separated by a spectral gap at the light line. The leaky regime …

Brazilian Adolescents Infected By Hiv: Epidemiologic Characteristics And Adherence To Treatment, Julia K. C. Machado, Maria J. C. Sant'anna, Veronica Coates, Flavia J. Almeida, Eitan N. Berezin, Hatim A. Omar

Pediatrics Faculty Publications

Over the last 3 decades since the first AIDS cases appeared, we have witnessed great progress in therapeutic methodologies that have transformed the evolution of the disease from debilitating and fatal, into chronic and controllable. HIV-infected children are arriving at adolescence and bringing specific challenges, not only to themselves, but also to their families and caregivers. This retrospective study sets forth epidemiological and treatment characteristics of 46 HIV-infected adolescents followed in a specialized university service relating said characteristics to therapy adherence assessed through a combination of three indirect methods. Therapy adherence did not reveal any association with either epidemiologic characteristics …

Assets And Child Well-Being In Developed Countries, Trina Williams Shanks, Youngmi Kim, Vernon Loke, Mesmin Destin

Center for Social Development Research

Although there is no universal approach to offering Child Development Accounts (CDAs), this paper introduces a framework for an age-based conceptual model that describes how such accounts might influence indicators of child wellbeing. With a focus on optimal age-appropriate development beginning at birth and ranging through young adulthood, the model incorporates research from multiple disciplines to include direct effects, indirect effects and critical milestones. We review empirical evidence from national datasets (primarily from the United States, but including research from other developed countries) to provide a context for this framework. This conceptual and empirical backdrop provides a starting point from …

Unraveling The Intricacies Of Spatial Organization Of The Erbb Receptors And Downstream Signaling Pathways, Michelle Costa

Chemical and Biological Engineering ETDs

Faced with the complexity of diseases such as cancer which has 1012 mutations, altering gene expression, and disrupting regulatory networks, there has been a paradigm shift in the biological sciences and what has emerged is a much more quantitative field of biology. Mathematical modeling can aid in biological discovery with the development of predictive models that provide future direction for experimentalist. In this work, I have contributed to the development of novel computational approaches which explore mechanisms of receptor aggregation and predict the effects of downstream signaling. The coupled spatial non-spatial simulation algorithm, CSNSA is a tool that I took …

Feature-Based Interactive Terrain Sketching, Daniel B. Adams

Theses and Dissertations

Procedural generation techniques are able to quickly and cheaply produce large areas of terrain. However, these techniques produce results that are not easily directable and often require artists to edit the results by hand to achieve the desired layout. This paper proposes a sketch-based system for controlling fractal terrain that allows for a wide variety of terrain feature types. Artists sketch features rather than constrained points or elevations. The system is interactive, provides quick on-demand previews of the terrain, and allows for iterative design modifications. Interaction between features is handled in a realistic fashion. An arbitrary vertex insertion order midpoint …

Future Cascadia Megathrust Rupture Delineated By Episodic Tremor And Slip, James S. Chapman, Timothy I. Melbourne

Faculty Scholarship for the Cascadia Hazards Institute

A suite of 15 episodic tremor and slip events imaged between 1997 and 2008 along the northern Cascadia subduction zone suggests future coseismic rupture will extend to 25 km depth, or approximately 60 km inland of the Pacific coast, rather than stopping offshore at 15 km depth. An ETS-derived coupling profile accurately predicts GPS measured interseismic deformation of the overlying North American plate, as measured by approximately 50 continuous GPS stations across western Washington State. When extrapolated over the 550-year average recurrence interval of Cascadia megathrust events, the coupling model also replicates the pattern and amplitude of coseismic coastal subsidence …
