Orbit Closures In The Enhanced Nilpotent Cone, Pramod N. Achar, Anthony Henderson

Faculty Publications

We study the orbits of G = GL (V) in the enhanced nilpotent cone V × N, where N is the variety of nilpotent endomorphisms of V. These orbits are parametrized by bipartitions of n = dim V, and we prove that the closure ordering corresponds to a natural partial order on bipartitions. Moreover, we prove that the local intersection cohomology of the orbit closures is given by certain bipartition analogues of Kostka polynomials, defined by Shoji. Finally, we make a connection with Kato's exotic nilpotent cone in type C, proving that the closure ordering is the same, and conjecturing …

Enumeration Of Rational Plane Curves Tangent To A Smooth Cubic, C. Cadman, Linda Chen

Mathematics & Statistics Faculty Works

We compute the number of rational degree d plane curves having prescribed fixed and moving contacts to a smooth plane cubic E . We use twisted stable maps to the stack View the MathML sourceP²_E,r for r large, where View the MathML sourceP²_E,r is the r th root of P² along E. We prove that certain Gromov–Witten invariants of this stack are enumerative, and establish recursive formulas for these numbers.

Towards Effective Automatic Parallelization For Multicore Systems, Uday Bondhugula, Muthu Baskaran, Albert Hartono, Sriram Krishnamoorthy, J. Ramanujam, Atanas Rountev, P. Sadayappan

Faculty Publications

The ubiquity of multicore processors in commodity computing systems has raised a significant programming challenge for their effective use. An attractive but challenging approach is automatic parallelization of sequential codes. Although virtually all production C compilers have automatic shared-memory parallelization capability, it is rarely used in practice by application developers because of limited effectiveness. In this paper we describe our recent efforts towards developing an effective automatic parallelization system that uses a polyhedral model for data dependences and program transformations. ©2008 IEEE.

Reduction Of Toxicity In The Premature Neonate Addociated With Aluminum As A Contaminant Of Total Parenteral Nutrition Solution, Sujittra Srisung

Dissertations

Aluminum (Al) is the third most common element in the Earth?s crust. It is widely consumed in water, foods, and drugs. However, in humans, the uptake of aluminum into the body and its deposition in tissues has been linked to conditions of medical concern, including many neurological disorders such as dialysis dementia, Alzheimer?s disease, Parkinson?s dementia and Down?s syndrome. Premature neonates who receive intravenous feeding (TPN) are at a high risk for Al toxicity because the TPN solutions are contaminated with Al3+, which is not excreted effectively due to poor kidney development in these patients. The FDA has recommended regulations …

Household Wealth And Heterogeneous Impacts Of A Market-Based Training Program: The Case Of Projoven In Peru, Jose Galdo, Miguel Jaramillo, Veronica S. Montalva, Sonia Moreau

Economics - All Scholarship

This paper analyzes the relationship between households' wealth and heterogeneous treatment impacts for a market-based training program that has benefited more than 40,000 disadvantaged individuals in Peru since 1996. We proxy long-run wealth by a linear index based on 21 household assets, and three main findings emerge. First, we find that voluntary choices among eligibles, rather than administrative choices, play a bigger role in explaining demographic disparities in program participation. Second, quantile treatment effects on the treated suggest important differences in program impacts at different quantiles of earnings, and strong differences in distributional impacts for men and women. Third, both …

Spray Deposition Of Biomolecular Thin Films, Mihir K. Rayan

USF Tampa Graduate Theses and Dissertations

In this paper, a parametric study of the airbrush deposition technique was investigated for the deposition biomolecular thin films. The airbrush parameters under investigation were intake valve opening, carrier gas pressure, distance between the airbrush and substrate, concentration of solution, vapor pressure of solvent, and hydrophobic/hydrophilic substrate surface. This study was assessed through the characterization of dried droplet residues of Bovine Serum Albumin (BSA) and of complete films of BSA by means of scanning electron microscopy (SEM) and atomic force microscopy (AFM). It was determined that droplet size was mainly affected by carrier gas pressure and vapor pressure. The parameters …

Can The Confluence Model Predict Female Sexual Aggression?, Nichole M. Clay-Valorio

Theses and Dissertations

The purpose of this exploratory investigation was to test the pathways of the Confluence Model of Sexual Aggression (Malamuth, Heavey & Linz, 1996) for prediction of self-reported female sexual aggression utilizing various computerized measures with college aged female participants (n = 104). The confluence model states that sexual aggression is the interactive result of two simultaneous pathways: hostile masculinity (and/or hostile femininity) and impersonal sex. It was hypothesized that a combination of either of the hostility pathways (feminine vs. masculine) and the impersonal sex pathway would predict sexual aggression. Modified versions of the Sexual Experiences Scale (SES), Coercive Sexuality Scale …

Water Quality Impacts From Agricultural Land Use In Karst Drainage Basins Of Sw Kentucky And Sw China, Chris Groves, Ted Baker

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes, and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into karst subsurface fluvial systems are often very similar to the concentrations surfacing at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be given to water quality impacts …

2008 Fall Engr333 Project Assignment, Matthew K. Heun

ENGR 333

The Fall 2008 semester ENGR333 project assessed the feasibility of a Green Revolving Fund for Calvin College. I asked the students “What would it take to implement a Calvin Energy Efficiency Fund (CEEF)?”

The project emerged from the work of the previous year’s students who uncovered the concept of green revolving funds.

Immediately after the Fall 2008 semester, I went on sabbatical to South Africa for all of 2009. While I was away, the Calvin administration established the Calvin Energy Recovery Fund (CERF). Over the next decade, CERF saved hundreds of thousands of dollars in energy costs and was …

Secure Referee Selection For Fair And Responsive Peer-To-Peer Gaming, Steven Daniel Webb, Sieteng Soh, Jerry L. Trahan

Faculty Publications

Peer-to-peer (P2P) architectures for Massively Multiplayer Online Games (MMOG) provide better scalability than Client/Server (C/S); however, they increase the possibility of cheating. Recently proposed P2P protocols use trusted referees that simulate/validate the game to provide security equivalent to C/S. When selecting referees from untrusted peers, selecting non-colluding referees becomes critical. Further, referees should be selected such that the range and length of delays to players is minimised (maximising game fairness and responsiveness). In this paper we formally define the referee selection problem and propose two secure referee selection algorithms, SRS-1 and SRS-2, to solve it. Both algorithms ensure the probability …

A Novel Method Characterizing The Impact Response Of Functionally Graded Plates, Reid A. Larson

Theses and Dissertations

Functionally graded material (FGM) plates are advanced composites with properties that vary continuously through the thickness of the plate. Metal-ceramic FGM plates have been proposed for use in thermal protection systems where a metal-rich interior surface of the plate gradually transitions to a ceramic-rich exterior surface of the plate. The ability of FGMs to resist impact loads must be demonstrated before using them in high-temperature environments in service. This dissertation presents a novel technique by which the impact response of FGM plates is characterized for low-velocity, low- to medium-energy impact loads. An experiment was designed where strain histories in FGM …

Preparation & Accreditation Of Level 7 Engineering Programmes, Mark Mcgrath

Conference Papers

Accreditation of 3rd level educational programmes by a suitably recognised professional body is of particular relevance in relation to engineering. The completion of a sequence of modules which leads to the attainment of this professionally recognised award is viewed as integral to the undertaking. The engineering technology fields are developing and expanding rapidly and the third level sector must keep abreast of these changes. This is essential if the third level institutions wish to continue delivering programmes which produce graduates who can successfully complete the transition from 3rd level to the various engineering sectors. This paper outlines various aspects of …

Segmenting Brain Tumors Using Pseudo-Conditional Random Fields, Chi-Hoon Lee, Shaojun Wang, Albert Murtha, Matthew R.G. Brown, Russell Greiner

Kno.e.sis Publications

Locating Brain tumor segmentation within MR (magnetic resonance) images is integral to the treatment of brain cancer. This segmentation task requires classifying each voxel as either tumor or non-tumor, based on a description of that voxel. Unfortunately, standard classifiers, such as Logistic Regression (LR) and Support Vector Machines (SVM), typically have limited accuracy as they treat voxels as independent and identically distributed (iid). Approaches based on random fields, which are able to incorporate spatial constraints, have recently been applied to brain tumor segmentation with notable performance improvement over iid classifiers. However, previous random field systems involved computationally intractable …

Measurements Of The Spectroscopic Properties Of Hydrogen Iodide Molecules, Zeyad Adnan Saleh

Baghdad Science Journal

A calculation have been carried out for determination some of the spectroscopic properties of Hydrogen Iodide HI molecules such as, the intensity of the absorption spectrum as a function of the variation of the temperature ranging from 10 to 1000 K. This study shows that the populations and hence intensity of the molecule increased as the temperature increased. Another determination of the maximum rotational quantum number Jmax of N2 , CO , BrF AgCl and HI molecules has been carried out.

Non-Profit Health Care Services Marketing: Persuasive Messages Based On Multidimensional Concept Mapping And Direct Magnitude Estimation, Michael L. Hall

Arts & Sciences Faculty Publications

Persuasive messages for marketing healthcare services in general and coordinated care in particular are more important now for providers, hospitals, and third-party payers than ever before. The combination of measurement based information with creativity may be among the most critical factors in reaching markets or expanding markets. The research presented here provides an approach to marketing coordinated care services which allows healthcare managers to plan persuasive messages given the market conditions they face. Using market respondents’ thinking about product attributes combined with distance measurement between pairs of product attributes, a conceptual marketing map is presented and applied to advertising, message …
