An Alternative Calendar In Select Middle Schools In An Urban City School District, Mattie Lee Solomon

All-Inclusive List of Electronic Theses and Dissertations

This study was conducted to understand parental perspectives on mandatory academies (intersessions) in three alternative (year-round) calendar middle schools. The alternative calendar was implemented by the study school district to improve student performance and parent attitudes toward the education their children receive. Academics (intersessions) are the source of time added to improve student performance. The three middle schools are located in an urban school district in the Midwestern state of Indiana. The students who attend are from lower socio-economic homes; the majority of the students live in homes where the guardian is a single mother or a member of the …

Independent Torque Distribution Management Systems For Vehicle Stability Control, Indrasen Karogal

All Theses

Vehicle Dynamics Control (VDC) systems, also called Electronic Stability Control (ESC) systems, are active on-board safety systems intended to stabilize the dynamics of vehicle lateral motion. In so doing, these systems reduce the possibility of the driver's loss of control of the vehicle in some critical or aggressive maneuvers. One approach to vehicle dynamics control is the use of appropriate drive torque distribution to the wheels of the vehicle. This thesis focuses on particular torque distribution management systems suitable for vehicles with independently driven wheels.
In conducting this study, a non-linear seven degree-of-freedom vehicle model incorporating a non-linear tire model …

A Performance And Productivity Study Using Mpi, Titanium, And Fortress, Amy Apon, Chris Bryan, Wesley Emeneker

Publications

The popularity of cluster computing has increased focus on usability, especially in the area of programmability. Languages and libraries that require explicit message passing have been the standard. New languages, designed for cluster computing, are coming to the forefront as a way to simplify parallel programming. Titanium and Fortress are examples of this new class of programming paradigms. This papers presents results from a productivity study of these two newcomers with MPI, the de- facto standard for parallel programming.

Growing Fields Of Interest: Using An Expand And Reduce Strategy For Domain Model Extraction, Christopher Thomas, Pankaj Mehra, Roger Brooks, Amit P. Sheth

Kno.e.sis Publications

Domain hierarchies are widely used as models underlying information retrieval tasks. Formal ontologies and taxonomies enrich such hierarchies further with properties and relationships associated with concepts and categories but require manual effort; therefore they are costly to maintain, and often stale. Folksonomies and vocabularies lack rich category structure and are almost entirely devoid of properties and relationships. Classification and extraction require the coverage of vocabularies and the alterability of folksonomies and can largely benefit from category relationships and other properties. With Doozer, a program for building conceptual models of information domains, we want to bridge the gap between the vocabularies …

Determining Chemical Signatures Of Geologic Materials For Establishing Provenience Of Anasazi Red And Gray Wares Using Esem-Eds And Icp-Ms, Champagne Springs Ruins, Co, Steven Mathew Di Naso

All-Inclusive List of Electronic Theses and Dissertations

Compositional analyses of prehistoric ceramics and geological materials allow archaeologists to establish provenience of artifacts through comparative analysis of the materials used in prehistoric ceramic production. Where pottery clay pastes and tempering constituents originate from locally or regionally available geological materials, identifying their chemical composition and their geographic location and distribution facilitates a better understanding of the inter and intra socio-spatial and socioeconomic patterns among neighboring communities. The Champagne Springs Ruins were occupied during the late Pueblo I (A.D. 700 -A.D. 900) to early Pueblo II (A.D. 900 TO A.D. 1100) periods. The traditional view of local ceramic production from …

Magnetohydrodynamic Effects In Propagating Relativistic Jets: Reverse Shock And Magnetic Acceleration, Yosuke Mizuno, Bing Zhang, Bruno Giacomazzo, Ken-Ichi Nishikawa, Phillip E. Hardee, Shigehiro Nagataki, Dieter H. Hartmann

Publications

We solve the Riemann problem for the deceleration of an arbitrarily magne-tized relativistic flow injected into a static unmagnetized medium in one dimen-sion. We find that for the same initial Lorentz factor, the reverse shock becomes progressively weaker with increasing magnetization σ (the Poynting-to-kinetic energy flux ratio), and the shock becomes a rarefaction wave when σ exceeds a critical value, σc, defined by the balance between the magnetic pressure in the flow and the thermal pressure in the forward shock. In the rarefaction wave regime, we find that the rarefied region is accelerated to a Lorentz factor that is significantly …

Historical Legacy Of Jesuits In China, Lawrence Fouraker

Verbum

In lieu of an abstract, below is the essay's first paragraph.

"What is the meaning today of the missionary activities of the Society of Jesus in China? The attempt by members of the Society of Jesus to convert Chinese to Christianity from the late-16^th to early-18^th centuries was part of the Catholic Reformation’s missionary expansion around the world. Was the Jesuit mission also part and parcel of an expansionist Western imperialism, or did it rather reflect a humanistic universalism?² Obviously, there are some aspects of both, but on balance, the conversion of Chinese in this era is …

Intelligence Techniques Are Needed To Further Enhance The Advantage Of Groups With Diversity In Problem Solving, Oscar Castillo, Patricia Melin, J. Esteban Gamez, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

In practice, there are many examples when the diversity in a group enhances the group's ability to solve problems -- and thus, leads to more efficient groups, firms, schools, etc. Several papers, starting with the pioneering research by Scott E. Page from the University of Michigan at Ann Arbor, provide a theoretical justification for this known empirical phenomenon. However, when the general advise of increasing diversity is transformed into simple-to-follow algorithmic rules (like quotas), the result is not always successful. In this paper, we prove that the problem of designing the most efficient group is computationally difficult (NP-hard). Thus, in …

A Model To Use Denied Internet Traffic To Indirectly Discover Internal Network Security Problems, Chet Langin, Hongbo Zhou, Shahram Rahimi

We propose a model for using firewall log entries of denied inbound Internet traffic for indirect discovery of local IP addresses that have security problems. This method is used successfully to discover two computers on the network of Southern Illinois University which were infected with malicious feral software, as well as two more IP addresses on the university network with other security problems.

Analysis Of Leading Economic Indicator Data And Gross Domestic Product Data Using Neural Network Methods, Edward Tirados, John Jenq

Department of Computer Science Faculty Scholarship and Creative Works

In this report, Leading Economic Indicator (LEI) data and Gross Domestic Product (GDP) data have been analyzed to determine if changes in the ten indicators can be used to predict changes in GDP. Three neural network methods and one statistical method were used to complete the analysis. For this project, the intent was to use multiple regression and backpropagation to develop correlations in which LEI values are used to predict the GDP change in the following quarter. Alternatively, Kohonen's self-organizing map and hierarchical clustering were used to group months of LEI data into clusters to determine if months in a …

A Reliable Approach For Higher-Order Integro-Differential Equations, Muhammad A. Noor, Syed T. Mohyud-Din

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we apply the variational iteration method (VIM) for solving higher-order integro differential equations by converting the problems into system of integral equations. The proposed technique is applied to the re-formulated system of integro-differential equations. Numerical results show the accuracy and efficiency of the suggested algorithm. The fact that the VIM solves nonlinear problems without calculating Adomian’s polynomials is a clear advantage of this technique over the decomposition method.

The Rhetoric Of Predictability: Reclaiming The Lay Ear In Music Copyright Infringement Litigation, Austin Padgett

The University of New Hampshire Law Review

[Excerpt] “Some things cannot be described. This is the theory that recent literary criticism has placed as its cornerstone. Philosopher-critic Roland Barthes identified this trend in his Mythologies, stating that critics often “suddenly decide that the true subject of criticism is ineffable, and criticism, as a consequence, unnecessary. Unfortunately, this view has become singular within the legal academy whenever an author discusses music copyright infringement analysis. It seems that scholars fear the thought of trusting a jury with such an “ineffable” subject as music and must propose alternatives, such as expert testimony, specialized courts, or mechanical analysis, that will diminish …

Scattering Of An Electromagnetic Plane Wave By A Luneburg Lens. I. Ray Theory, James A. Lock

Physics Faculty Publications

For a plane wave incident on either a Luneburg lens or a modified Luneburg lens, the magnitude and phase of the transmitted electric field are calculated as a function of the scattering angle in the context of ray theory. It is found that the ray trajectory and the scattered intensity are not uniformly convergent in the vicinity of edge ray incidence on a Luneburg lens, which corresponds to the semiclassical phenomenon of orbiting. In addition, it is found that rays transmitted through a large-focal-length modified Luneburg lens participate in a far-zone rainbow, the details of which are exactly analytically soluble …

Scattering Of An Electromagnetic Plane Wave By A Luneburg Lens. Ii. Wave Theory, James A. Lock

Physics Faculty Publications

The partial wave scattering and interior amplitudes for the interaction of an electromagnetic plane wave with a modified Luneburg lens are derived in terms of the exterior and interior radial functions of the scalar radiation potentials evaluated at the lens surface. A Debye series decomposition of these amplitudes is also performed and discussed. The effective potential inside the lens for the transverse electric polarization is qualitatively examined, and the approximate lens size parameters of morphology-dependent resonances are determined. Finally, the physical optics model is used to calculate wave scattering in the vicinity of the ray theory orbiting condition in order …

Scattering Of An Electromagnetic Plane Wave By A Luneburg Lens. Iii. Finely Stratified Sphere Model, James A. Lock

Physics Faculty Publications

The parallel iteration procedure for computing scattering by a multilayer sphere is described. The procedure uses a successive doubling strategy applied to four sets of multiple-scattering amplitudes, which is reminiscent of the fast Fourier transform (FFT) algorithm. The procedure is then used to calculate scattering of a plane wave by a modified Luneburg lens. The evolution of the transmission rainbow for the Luneburg lens parameter f > 1 into an orbiting ray for f = 1 and into a series of morphology-dependent resonances for f < 1 is studied, and various features of the scattered intensity as a function of scattering angle are commented on. It is found that some resonances are formed without the presence of an exterior centrifugal barrier to confine them. (C) 2008 Optical Society of America

Rainbows In The Grass. I. External Reflection Rainbows From Pendant Droplets, James A. Lock, Charles L. Adler, Richard W. Fleet

Physics Faculty Publications

In the mid-morning on a sunny day one can sometimes see glare spots associated with uncolored "rainbow" (i.e., fold) caustics due to the sunlight reflected from the surface of dew or guttation drops. We show that these dewdrop reflection rainbows are due to places on the droplet (i.e., from an "inflection circle") where its Gaussian curvature becomes zero. We work out the theory of such caustics with horizontally incident light and present a comparison of the theory to measurements made in the laboratory. (C) 2008 Optical Society of America

Rainbows In The Grass. Ii. Arbitrary Diagonal Incidence, Charles L. Adler, James A. Lock, Richard W. Fleet

Physics Faculty Publications

We consider external reflection rainbow caustic,,; due to the reflection of light from a pendant droplet where the light rays are at an arbitrary angle with respect to the horizontal. We compare this theory to observation of glare spots from, pendant drops on grass; we also consider the potential application of this theory to the determination of liquid surface tension.

Ballot Mark Detection, Elisa H. Barney Smith, Daniel Lopresti, George Nagy

Electrical and Computer Engineering Faculty Publications and Presentations

Optical mark sensing, i.e., detecting whether a "bubble" has been filled in, may seem straightforward. However, on US election ballots the shape, intensity, size and position of the marks, while specified, are highly variable due to a diverse electorate. The ballots may be produced and scanned by poorly maintained equipment. Yet near-perfect results are required. To improve the current technology, which has been subject to criticism, components of a process for identifying marks on an optical sense ballot are evaluated. When marked synthetic ballots are compared to an unmarked ballot, the absolute difference of adaptive thresholded images gives best detection …

Global Irrigation Water Demand: Variability And Uncertainties Arising From Agricultural And Climate Data Sets, Dominik Wisser, Steve Frolking, Ellen M. Douglas, Balazs M. Fekete, Charles Vorosmarty, Andreas H. Schumann

Earth Sciences

Agricultural water use accounts for around 70% of the total water that is withdrawn from surface water and groundwater. We use a new, gridded, global-scale water balance model to estimate interannual variability in global irrigation water demand arising from climate data sets and uncertainties arising from agricultural and climate data sets. We used contemporary maps of irrigation and crop distribution, and so do not account for variability or trends in irrigation area or cropping. We used two different global maps of irrigation and two different reconstructions of daily weather 1963–2002. Simulated global irrigation water demand varied by ∼30%, depending on …

Recovery From A Cycling Time Trial Is Enhanced With Carbohydrate-Protein Supplementation Vs. Isoenergetic Carbohydrate Supplementation, John M. Berardi, Eric E. Noreen, Peter W.R. Lemon

Health Sciences Faculty Publications

Background: In this study we assessed whether a liquid carbohydrate-protein (C+P) supplement (0.8 g/kg C; 0.4 g/kg P) ingested early during recovery from a cycling time trial could enhance a subsequent 60 min effort on the same day vs. an isoenergetic liquid carbohydrate (CHO) supplement (1.2 g/kg).

Methods: Two hours after a standardized breakfast, 15 trained male cyclists completed a time trial in which they cycled as far as they could in 60 min (AMex) using a Computrainer indoor trainer. Following AMex, subjects ingested either C+P, or CHO at 10, 60 and 120 min, followed by a standardized meal at …

On Existence And Uniqueness Theorem Concerning Time–Dependent Heat Transfer Model, Naji A. Qatanani, Qasem M. Heeh

Applications and Applied Mathematics: An International Journal (AAM)

In this article we consider a physical model describing time-dependent heat transfer by conduction and radiation. This model contains two conducting and opaque materials which are in contact by radiation through a transparent medium bounded by diffuse-grey surfaces. The aim of this work is to present a reliable framework to prove the existence and the uniqueness of a weak solution for this problem. The existence of the solution can be proved by solving an auxiliary problem by the Galerkin-based approximation method and Moser-type arguments which implies the existence of solution to the original problem. The uniqueness of the solution will …

An Object-Oriented Approach For Modeling And Simulation Of Crack Growth In Cyclically Loaded Structures, D. Cojocaru, Anette M. Karlsson

Mechanical Engineering Faculty Publications

We present an object-oriented modeling frame for simulating crack propagation due to cyclic loadings. Central to the approach is that the crack propagates when a user-defined propagation criterion is fulfilled, i.e., the crack propagation rate is not prescribed but predicted. The approach utilizes the commercial finite element software package ABAQUS and its associated Python based scripting interface. The crack propagation is simulated by a generalized node release technique. If the propagation criteria are satisfied in the end of a cycle, the crack is allowed to propagate. The incremental crack growth is inferred from an iterative investigation of the propagation criteria. …

Changing The Negative Behavioral And Development Outcomes To A Toxic Prenatal Environment Through Maternal Education, Angela Eileen Laughlin Lebedev

Walden Dissertations and Doctoral Studies

The purpose of this study was to evaluate the effectiveness of current education materials on changing maternal smoking attitudes. Children are affected by prenatal exposure to tobacco smoke. Although there are educational efforts to discourage pregnant women from smoking, the practice continues in a significant number of pregnancies. New materials, based on current research, were also evaluated for effectiveness. The theoretical framework for this study was adult learning theory presented by Knowles which made the assumption that an individual is shaped by environmental systems, that adult learning is affected by previous knowledge they bring to the learning and that adults …
