A Note On Solid Coloring Of Pure Simplicial Complexes, Joseph O'Rourke

Computer Science: Faculty Publications

We establish a simple generalization of a known result in the plane. The simplices in any pure simplicial complex in R^d may be colored with d+1 colors so that no two simplices that share a (d-1)-facet have the same color. In R² this says that any planar map all of whose faces are triangles may be 3-colored, and in R³ it says that tetrahedra in a collection may be "solid 4-colored" so that no two glued face-to-face receive the same color.

H-Ns Binding And Repression Of The Ctx Promoter In Vibrio Cholerae, Emily A. Stonehouse, Robin R. Hulbert, Melinda B. Nye, Karen Skorupski, Ronald K. Taylor

Dartmouth Scholarship

Expression of the ctx and tcp genes, which encode cholera toxin and the toxin coregulated pilus, the Vibrio cholerae O1 virulence determinants having the largest contribution to cholera disease, is repressed by the nucleoid-associated protein H-NS and activated by the AraC-like transcriptional regulator ToxT. To elucidate the molecular mechanism by which H-NS controls transcription of the ctxAB operon, H-NS repression and binding were characterized by using a promoter truncation series, gel mobility shift assays, and DNase I footprinting. Promoter regions found to be important for H-NS repression correlated with in vitro binding. Four main H-NS binding regions are present at …

Scanning Laser Registration And Structural Energy Density Based Active Structural Acoustic Control, Daniel Alan Manwill

Theses and Dissertations

To simplify the measurement of energy-based structural metrics, a general registration process for the scanning laser doppler vibrometer (SLDV) has been developed. Existing registration techniques, also known as pose estimation or position registration, suffer from mathematical complexity, instrument specificity, and the need for correct optimization initialization. These difficulties have been addressed through development of a general linear laser model and hybrid registration algorithm. These are applicable to any SLDV and allow the registration problem to be solved using straightforward mathematics. Additionally, the hybrid registration algorithm eliminates the need for correct optimization initialization by separating the optimization process from solution selection. …

Analysis Of A Queueing Model With Service Threshold, Kathryn Graf

Theses

We study a variation of the M/G/1 queueing model in which service time of customers is modified depending on the class to which the customers belong. Specifically, apart from the regular service time, we consider different service times for every customer who starts service after an idle and also for every (m+1)st customer. The model represents situations such as when the system requires a warm up time from a cold start (i.e.) after being idle for some time and also a system that is taken down at regular intervals perhaps for maintenance. Such systems come under the general class of …

Implementing Frequency Regulation Capability In A Solar Photovoltaic Power Plant, Venkata Ajay Kumar Pappu, Badrul H. Chowdhury, Ravi Bhatt

Electrical and Computer Engineering Faculty Research & Creative Works

Photovoltaic power plants pose some challenges when integrated with the power grid. the PV plants always focus on extracting the maximum power from the arrays. This makes the PV system unavailable for helping in regulating the grid frequency as compared to conventional generators. the objective of this paper is to introduce a pseudo power point tracking which provides frequency regulation functionality to PV systems. This method is fast and helps in creating a reserve which can be utilized for frequency stability. Control technique discussed in this paper allows the control over the amount of active power injected into the grid. …

Reconciling Motor Performance Indicators From Theoretical Calculations And Laboratory Tests, Himanshu Hirlekar, Badrul H. Chowdhury, Stephen Ruffing

Electrical and Computer Engineering Faculty Research & Creative Works

Quite often because of the complexity in the design of large industrial motors, the theoretical motor parameter calculations do not match actual results from laboratory tests. Thus, it becomes important to predict the amount of discrepancy between the two methods to develop confidence in the motor parameter calculations. This paper discusses the development of multiple artificial neural networks (ANNs) designed to predict the ratios of measured parameters to calculated parameters, given the geometry and construction of the motor. These ratios represent correction factors which can be applied to the values calculated from the theoretical program, which, in this case, is …

Movies Of Electrons In Atoms, Michael Schirber, Hua-Chieh Shao, Anthony F. Starace

Anthony F. Starace Publications

Physicists have long been able to snap atomic-scale pictures by shining a beam of electrons at a target, but filming the electronic structure of an atom as it changes in time is the next goal. A rapid "strobing" of electron pulses less than a millionth of a billionth of a second long should do the trick, according to a theoretical analysis in the 24 December Physical Review Letters. The authors demonstrate with computer simulations that ultrafast electron pulses could track the "breathing" state of an excited atom or the hopping of electrons between atoms in a molecule. Such movies open …

The Effect Of Raters And Rating Conditions On The Reliability Of The Missionary Teaching Assessment, Abigail Christine Ure

Theses and Dissertations

This study investigated how 2 different rating conditions, the controlled rating condition (CRC) and the uncontrolled rating condition (URC), effected rater behavior and the reliability of a performance assessment (PA) known as the Missionary Teaching Assessment (MTA). The CRC gives raters the capability to manipulate (pause, rewind, fast-forward) video recordings of an examinee's performance as they rate while the URC does not give them this capability (i.e., the rater must watch the recording straight through without making any manipulations). Few studies have compared the effect of these two rating conditions on ratings. Ryan et al. (1995) analyzed the impact of …

The Effects Of Using Clinical Support Tools To Prevent Treatment Failure, Tiffany K. Washington

Theses and Dissertations

To date, outcome research suggests that providing clinicians with patient progress feedback and problem-solving tools is effective in improving therapeutic outcome for clients who are predicted to have a negative treatment outcome. To expand upon this body of research, the current study examined the efficacy of using these problem-solving tools (Clinical Support Tools; CST) to reduce the risk of treatment failure and enhance positive outcome with 118 clients who were not identified as at -risk for a negative outcome. Results of this study indicated that the intervention failed to lower the rate of becoming an at-risk case or to enhance …

Implementation Of Separable & Steerable Gaussian Smoothers On An Fpga, Arjun Joginipelly

LSU New Orleans Theses and Dissertations

Smoothing filters have been extensively used for noise removal and image restoration. Directional filters are widely used in computer vision and image processing tasks such as motion analysis, edge detection, line parameter estimation and texture analysis. It is practically impossible to tune the filters to all possible positions and orientations in real time due to huge computation requirement. The efficient way is to design a few basis filters, and express the output of a directional filter as a weighted sum of the basis filter outputs. Directional filters having these properties are called "Steerable Filters." This thesis work emphasis is on …

Toward A Database Of Geometric Interrelationships Of Protein Secondary Structure Elements For De Novo Protein Design, Prediction And Analysis, Augustine Ada Orgah

LSU New Orleans Theses and Dissertations

Computational methods of analyzing, simulating, and modeling proteins are essential towards understanding protein structure and its interactions. Computational methods are easier as not all protein structures can be determined experimentally due to the inherent difficultly of working with some proteins. In order to predict, design, analyze, simulate or model a protein, data from experimentally determined proteins such as those located in the repository of the Protein Data Bank (PDB) are essential. The assumption here is that we can use pieces of known proteins to piece together a "new" protein hence, de novo protein design. The analysis of the geometric relationships …

LSU New Orleans Theses and Dissertations

A mild gasification method has been developed to provide an innovative clean coal technology. The objective of this study is to developed a numerical model to investigate the thermal-flow and gasification process inside a specially designed fluidized-bed mild gasifier using the commercial CFD solver ANSYS/FLUENT. Eulerain-Eulerian method is employed to calculate both the primary phase (air) and secondary phase (coal particles). The Navier-Stokes equations and seven species transport equations are solved with three heterogeneous (gas-solid), two homogeneous (gas-gas) global gasification reactions. Development of the model starts from simulating single-phase turbulent flow and heat transfer to understand the thermal-flow behavior followed …

A Web Service For Protein Refinement And Refinement Of Membrane Proteins, Kapil Pothakanoori

LSU New Orleans Theses and Dissertations

The structures obtained from homology modeling methods are of intermediate resolution 1-3Ã… from true structure. Energy minimization methods allow us to refine the proteins and obtain native like structures. Previous work shows that some of these methods performed well on soluble proteins. So we extended this work on membrane proteins. Prediction of membrane protein structures is a particularly important, since they are important biological drug targets, and since their number is vanishingly small, as a result of the inherent difficulties in working with these molecules experimentally. Hence there is a pressing need for alternative computational protein structure prediction methods. This …
