Toral Algebraic Sets And Function Theory On Polydisks, Jim Agler, John E. Mccarthy, Mark Stankus

Mathematics

A toral algebraic set A is an algebraic set in Cⁿ whose intersection with Tⁿ is sufficiently large to determine the holomorphic functions on A. We develop the theory of these sets, and give a number of applications to function theory in several variables and operator theoretic model theory. In particular, we show that the uniqueness set for an extremal Pick problem on the bidisk is a toral algebraic set, that rational inner functions have zero sets whose irreducible components are not toral, and that the model theory for a commuting pair of contractions with finite defect …

Regression Cubes With Lossless Compression And Aggregation, Yixin Chen, Guozhu Dong, Jiawei Han, Jian Pei, Benjamin W. Wah, Jianyong Wang

Kno.e.sis Publications

As OLAP engines are widely used to support multidimensional data analysis, it is desirable to support in data cubes advanced statistical measures, such as regression and filtering, in addition to the traditional simple measures such as count and average. Such new measures will allow users to model, smooth, and predict the trends and patterns of data. Existing algorithms for simple distributive and algebraic measures are inadequate for efficient computation of statistical measures in a multidimensional space. In this paper, we propose a fundamentally new class of measures, compressible measures, in order to support efficient computation of the statistical models. For …

Oscillations Of Hyperbolic Systems With Functional Arguments, Yutaka Shoukaku, Norio Yoshida

Applications and Applied Mathematics: An International Journal (AAM)

Hyperbolic systems with functional arguments are studied, and sufficient conditions are obtained for every solution of boundary value problems to be weakly oscillatory (that is, at least one of its components is oscillatory) in a cylindrical domain. Robin-type boundary condition is considered. The approach used is to reduce the multi-dimensional oscillation problems to one-dimensional oscillation problems by using some integral means of solutions.

For Piecewise Smooth Signals, L1 Method Is The Best Among Lp: An Interval-Based Justification Of An Empirical Fact, Vladik Kreinovich, Arnold Neumaier

Departmental Technical Reports (CS)

Traditional engineering techniques use the Least Squares method (i.e., in mathematical terms, the l2-norm) to process data. It is known that in many practical situations, lp-methods with p=/=2 lead to better results. In different practical situations, different values of p are optimal. It is known that in several situations when we need to reconstruct a piecewise smooth signal, the empirically optimal value of p is close to 1. In this paper, we provide a new interval-based theoretical explanation for this empirical fact.

Home Management System: Application Development For Inventory Management, Lea Herr

Regis University Student Publications (comprehensive collection)

Societal trends have resulted in fuller schedules, and more dual income and single parent families. Time management has become more challenging for American families; therefore it has become more difficult to effectively and efficiently perform household management tasks. A computerized home management system would simplify, organize, and expedite home management processes. The goal of this project was the completion of the first module of a computerized home management system. Inventory management was chosen due to its critical part in home management. The application is characterized by a user interface designed to enable family members from kindergarten age and up to …

Developing A Java Application To Assist Conceptual Modeling For Discrete-Event Simulation (Cms-Proto), Wei Ling Chang

All-Inclusive List of Electronic Theses and Dissertations

Simulation is a useful tool that helps managers and engineers model and analyze the behavior of real systems. In business or industry, decision makers can efficiently and effectively make critical decisions by using simulations to design models and test possible solutions. Using simulation can reduce cost, improve quality and productivity, make effective process design, and shorten time to market. However, conducting simulation study requires kl).owledge of application, simulation and implementation domains, and there is a lack of tools to help modelers efficiently transform and integrate knowledge and information to build conceptual simulation models. This creates a gap for modelers to …

Modeling Soil Erosion In The Upper Green River, Ky, Narcisa Pricope

Masters Theses & Specialist Projects

Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease in the transport capacity of streams, increase in the risk of flooding, filling reservoirs, and eutrophication. A primary focus in examining the problems associated with soil erosion arid ultimately in proposing control measures should be on identifying the sources of the sediment. Therefore, a model that would be able to assess soil erosion needs to start by identifying the …

Flash Flooding In Eastern Kentucky: An Analysis Of The 3-4 August 2001 Event, Christina Henry

Masters Theses & Specialist Projects

Limited research exists concerning flash flooding in the United States. However, flash floods can occur anywhere and cause more fatalities than any other weather related natural disaster. Eastern Kentucky experienced an average of 41 flash floods per year (1993-2002), yet little research exists for this region. Therefore, this paper presents an analysis of the particularly devastating flash flood event of 3-4 August 2001, which resulted in $15 million worth of property damage and two deaths. Previous studies indicate that flash floods typically occur under relatively 'benign' conditions, the most common characteristics being a quasi-stationary system and high atmospheric moisture. The …

An Investigation Of Developmentally Appropriate Methods In Teaching Drawing, Mark Esguerra

Regis University Student Publications (comprehensive collection)

This is an investigation sought to identify developmentally appropriate teaching methods in drawing instruction. This study assessed the different methods in teaching the fundamentals of drawing to two groups of 5th grade classes at Our Lady of Las Vegas School in Las Vegas, Nevada. The "control" group was taught by the drawing methods presented by Edwards (1979), while the "experimental" group was taught employing standard methods. Their drawing skills were assessed using a rubric that measured their success in the following four dimensions of drawing: perspective, proportion, value and composition. The study utilized the pretest-posttest control group design (Leedy & …

Network Infrastructure Essentials Course Development, Michael A. Case

Regis University Student Publications (comprehensive collection)

Voice and data cabling enable people around the world to communicate by phone, fax, and computer. Cabling is the basis for virtually every network. Today's voice and data cabling is engineered to balance high performance with cost efficiency. The quality of the service provided by the cabling is directly related to the quality of the installation. Properly installed cabling can provide years of service for networks, in most cases outlasting every device connected to the network. Experience has taught us that too many people don't realize the importance of cable infrastructure. At Alfred State College, in the Computer Engineering Technology …

A Partially Discretized Age-Dependent Population Model With An Additional Stucture, Jean Tchuenche

Applications and Applied Mathematics: An International Journal (AAM)

A semi-discretization method for solving an age-dependent population dynamics model with an additional structure is proposed. This method, unlike previous ones, considers the partial discretization which reduces the model equation into a first order ordinary differential equation. The latter is then solved explicitly and conditions under which second order accuracy arises are given. While the approach adopted is basically analytical, the main result shows that the sum of errors is bounded. An extension to the non-trivial case where growth depends on the additional parameter leads to a Riccati equation, and the existence and
convergence of solutions are proved.

Biomass Estimation And Classification Of Secondary Succession Using Radar And Optical Remote Sensing Data Based On Textural And Spectral Analysis In Amazonia, Ping Jiang

All-Inclusive List of Electronic Theses and Dissertations

Deforestation that happened during past decades in the Amazon Basin has been potentially affecting the global climate and carbon-cycle by contributing a vast amount of carbon into the atmosphere. Above-ground biomass (AGB) estimation of secondary successional and mature forests using remote sensing technology has been attracting scientists' attention. Optical sensor data are sensitive to forest canopies only, and therefore have limitations in AGB estimation, especially for tropical forests with complex structures and abundant species. Radar signals have the ability to penetrate canopies to detect the sub-layers of forests, and therefore potentially have a better performance in AGB estimation. Based on …

Optical And X-Ray Variability Of Agns, C. Martin Gaskell

C. Martin Gaskell Publications

I present new comparisons of AGN optical, UV, and X-ray variations. These reveal complex relationships between the different passbands that can change with time in a given object. While there is evidence from several objects that X-ray and optical activity levels are correlated on long timescales, variations on shorter timescales can occur independently. It is proposed that the combination of correlated and uncorrelated short-timescale variability is a consequence of anisotropic high-energy emission. It is also argued that the correlation between X-ray and optical variability on long timescales must be due to a common underlying factor and not to reprocessing of …

Optical Variability Of The Three Brightest Nearby Quasars, C. Martin Gaskell, Andrew J. Benker, Jeffrey S. Campbell, Thomas A. George, Cecilia H. Hedrick, Mary E. Hiller, Elizabeth S. Klimek, Joseph P. Leonard, Shoji Masatoshi, Bradley W. Peterson, Kelly S. Peterson, Kelly M. Sanders

C. Martin Gaskell Publications

We report on the relative optical variability of the three brightest nearby quasars, 3C 273, PDS 456, and PHL 1811. All three have comparable absolute magnitudes, but PDS 456 and PHL 1811 are radio quiet. PDS 456 is a broadline object, but PHL 1811 could be classified as a high-luminosity Narrow-Line Seyfert 1 (NLS1). Both of the radio-quiet quasars show significant variability on a timescale of a few days. The seasonal rms V-band variability amplitudes of 3C 273 and PDS 456 are indistinguishable, and the seasonal rms variability amplitude of PHL 1811 was only exceeded by 3C 273 once in …

The Origin Of Wavelength-Dependent Continuum Delays In Agns – A New Model, C. Martin Gaskell

C. Martin Gaskell Publications

A model of wavelength-dependent lags in optical continuum variability of AGNs is proposed which avoids the problems of the popular “lamppost” model. Rather than being due to reprocessing of high-energy radiation from a hypothetical source above the accretion disk, the wavelength-dependent delays observed from the B to I bands are instead due to contamination of an intrinsically coherently variable continuum with the Wien tail of the thermal emission from the hot dust in the surrounding torus. The new model correctly gives the size, wavelength dependence, and luminosity dependence of the lags, and quantitatively predicts observed color hysteresis. The model also …

Cash Reserve And Venture Business Survival Probability, Sheen Liu, Peter Woodlock, Howard Qi, Yan Alice Xie

The Journal of Entrepreneurial Finance

Both solid business ventures and those not on as firm a footing can fail because they do not manage risk properly. This study shows that start-ups with a positive NPV project can fail because of inadequate cash reserves. We apply the first-hitting time model to analyze the effect of a cash reserve on the business failure density function and the cumulative failure probability for a specific business venture. The analysis of this model shows that business ventures have a much higher survival probability when they reduce their future cash-flow volatility. It is also shown that when risks cannot be controlled …

Spring Ephemeral Plant Diversity As It Relates To Gap Dynamics In Vigo County, Indiana, Jodi K. Farrell Sparks

All-Inclusive List of Electronic Theses and Dissertations

During the course of 25 years, plant specimens from several local locations have been collected and deposited into the Indiana State University (ISU) Herbarium by plant taxonomy students. The locations of some of these plots were reestablished in the spring of 2004. In each plot, all woody and spring herbaceous plants were collected from 26 February 2004 to 12 May 2004. These specimens were identified and compared to previous collections to examine species change in the context of gap dynamics. I compiled a species list for each plot and each preserve. Objectives for this thesis were to document plant diversity …

Generating New Specific Rna Interaction Interfaces Using C-Loops, Kirill A. Afonin, Neocles B. Leontis

Chemistry Faculty Publications

New RNA interaction interfaces are reported for designing RNA modules for directional supramolecular self-assembly. The new interfaces are generated from existing ones by inserting C-loops between the interaction motifs that mediate supramolecular assembly. C-Loops are new modular motifs recently identified in crystal structures that increase the helical twist of RNA helices in which they are inserted and thus reduce the distance between pairs of loop or loop-receptor motifs from 11 to 9 base-stacking layers while maintaining correct orientation for binding to cognate interaction interfaces. Binding specificities of C-loop-containing molecules for cognate molecules that also have inserted C-loops were found to …
