Kenneth Burke, The Basic Communication Course, And Applied Scholarship, Scott Titsworth, Ben Bates, Pam Kenniston

Basic Communication Course Annual

The Journal of Applied Communication Research published a forum of position papers in 2000 (Volume 28, Issue 2) that sought to define “applied communication research.” Collectively, the authors called for scholarship that embodies a reflexive relationship between theory and practice (O’Hair, 2000; Keyton, 2000, Cissna, 2000; Eadie, 2000; Frey, 2000; Seibold, 2000; Wood, 2000). In this essay, we call for applied scholarship that focuses on how we talk, perform, and theorize the basic communication course. Drawing from the works of Kenneth Burke (e.g., 1931/1968; 1935; 1937/1984; 1941/ 1967; 1945/1969; 1954/1984), we focus specifically on the salience of discourses of and …

Concurrent Multiple- Issue Negotiation For Internet-Based Services, Jiangbo Dang, Michael N. Huhns

Faculty Publications

Negotiation is a technique for reaching a mutually beneficial agreement among autonomous entities. In an Internet-based services context, multiple entities are negotiating simultaneously. The concurrent negotiation protocol extends existing negotiation protocols, letting both service requestors and service providers manage several negotiation processes in parallel. Colored Petri nets, which have greater expressive power than finite state machines and offer support for concurrency, represent the negotiation protocol and facilitate the analysis of desirable properties.

Religion In The Classroom In Germany And The United States, Edward J. Eberle

Law Faculty Scholarship

In this Article, Professor Eberle evaluates the relationship of religion in the classroom in Germany and the United States, as formulated by the countries' highest courts, the German Constitutional Court and the United States Supreme Court Pursuant to the German model of church-state cooperation, public finds are channeled to religious organizations, such as, for example, using the machinery of the state to rise and disperse tax monies to religious organizations. Religious groups may then use the tax monies collected to support religious education in the public schools. However, pursuant to guidelines announced by the German Constitutional Court, teaching of religious …

Melting And Solidification Study Of As-Deposited And Recrystallized Bi Thin Films, M. K. Zayed, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Melting and solidification of as-deposited and recrystallized Bi crystallites, deposited on highly oriented 002-graphite at 423 K, were studied using reflection high-energy electron diffraction (RHEED). Films with mean thickness between 1.5 and 33 ML (monolayers) were studied. Ex situ atomic force microscopy was used to study the morphology and the size distribution of the formed nanocrystals. The as-deposited films grew in the form of three-dimensional crystallites with different shapes and sizes, while those recrystallized from the melt were formed in nearly similar shapes but different sizes. The change in the RHEED pattern with temperature was used to probe the melting …

A Fast Parallelized Computational Approach Based On Sparse Lu Factorization For Predictions Of Spatial And Time-Dependent Currents And Voltages In Full-Body Biomodels, Ashutosh Mishra, Ravindra P. Joshi, Karl H. Schoenbach, C. D. Clark Iii

Electrical & Computer Engineering Faculty Publications

Realistic and accurate numerical simulations of electrostimulation of tissues and full-body biomodels have been developed and implemented. Typically, whole-body systems are very complex and consist of a multitude of tissues, organs, and subcomponents with diverse properties. From an electrical standpoint, these can be characterized in terms of separate conductivities and permittivities. Accuracy demands good spatial resolution; thus, the overall tissue/animal models need to be discretized into a fine-grained mesh. This can lead to a large number of grid points (especially for a three-dimensional entity) and can place prohibitive requirements of memory storage and execution times on computing machines. Here, the …

Resource Recovery Of Coal Bed Methane Formation Water, Catherine Elizabeth Bishop

LSU Master's Theses

During the excavation of natural gas, petroleum hydrocarbon-polluted brine water, termed production water, is drawn from the coal bed methane formations (CBMF) along with the natural gas product. The water is drawn out in vast amounts and re-injected into the CBMF. In the Greater Rocky Mountain Region (GRMR) where water supplies are dwindling, the remediation of CBMF production water has become a high priority for maintaining agriculture, residential development and industrial expansion. The overall objective of this research was to demonstrate in laboratory and field pilot studies the efficacious merging of Immobilized Microbe BioReactor (IMBR) technologies for biodegradation/mineralization of organics …

Study Of Reliable Data Communication In Wireless Sensor Networks, Ravilochan G. Shamanna

LSU Master's Theses

A distributed wireless sensor network consists of numerous tiny autonomous sensing nodes deployed across a wide geographical area. These sensor nodes self organize and establish radio communication links with the neighboring nodes to form multi-hop routing paths to the central base station. The dynamic and lossy nature of wireless communication poses several challenges in reliable transfer of data from the sensor nodes to the sink. There are several applications of sensor networks wherein the data collected by the sensors in the network are critical and hence have to be reliably transported to the sink. An example of such an application …

Wavelet Analysis In Virtual Colonoscopy, Sharon Greenblum, Jiang Li, Adam Huang, Ronald M. Summers, Armando Manduca (Ed.), Amir A. Amini (Ed.)

Electrical & Computer Engineering Faculty Publications

The computed tomographic colonography (CTC) computer aided detection (CAD) program is a new method in development to detect colon polyps in virtual colonoscopy. While high sensitivity is consistently achieved, additional features are desired to increase specificity. In this paper, a wavelet analysis was applied to CTCCAD outputs in an attempt to filter out false positive detections. 52 CTCCAD detection images were obtained using a screen capture application. 26 of these images were real polyps, confirmed by optical colonoscopy and 26 were false positive detections. A discrete wavelet transform of each image was computed with the MATLAB wavelet toolbox using the …

Hybrid Committee Classifier For A Computerized Colonic Polyp Detection System, Jiang Li, Jianhua Yao, Nicholas Petrick, Ronald M. Summers, Amy K. Hara, Joseph M. Reinhardt (Ed.), Josien P.W. Pluim (Ed.)

Electrical & Computer Engineering Faculty Publications

We present a hybrid committee classifier for computer-aided detection (CAD) of colonic polyps in CT colonography (CTC). The classifier involved an ensemble of support vector machines (SVM) and neural networks (NN) for classification, a progressive search algorithm for selecting a set of features used by the SVMs and a floating search algorithm for selecting features used by the NNs. A total of 102 quantitative features were calculated for each polyp candidate found by a prototype CAD system. 3 features were selected for each of 7 SVM classifiers which were then combined to form a committee of SVMs classifier. Similarly, features …

Art Informing Science Education: The Potential Contributions Of Ornithological Illustration To Ecology Education, Vanessa Hunt

LSU Doctoral Dissertations

Birds serve as an excellent group of organisms from which to introduce the study of ecology, being of inherent aesthetic interest to many otherwise uninterested in science, and are also ubiquitous in the immediate environment of many students. By extension, images of birds might serve as a valuable resource for the ecology educator, and bird artists – as a subset of ecologists - might provide useful models for expertise in ecology. This study examines the potential contributions of bird artists and bird art to education in ecology at the high school and college level. Eight contemporary bird artists were interviewed …

Econometric Essays On Specification And Estimation Of Demand Systems, Anil Kumar Sulgham

LSU Doctoral Dissertations

This dissertation focuses on two research themes related to econometric estimation of linear almost ideal demand systems (LAIDS) for U.S. meats. The first theme addresses whether nonstationarity (unit-roots and cointegration) contributes to a dynamic specification of LAIDS models. The results of the effect of nonstationarity are reported in two case studies. The second theme explores the relationship between age and household size with budget shares to specify semiparametric LAIDS model. The results are reported in a third case study that compares parametric and semiparametric models estimates of price and expenditure elasticities. The first case study conducts a comparative analysis of …

Spatial Distribution Of Heavy Metals In Louisiana Sediments And Study Of Factors Impacting The Concentrations, Suniti Bhattarai

LSU Master's Theses

To identify the sites with elevated metal concentrations and factors impacting the concentrations, we studied 128 observations on heavy metals collected from the four inch deep sediments in Louisiana lakes and rivers. Use of Fe as a normalizing factor to interpret the site of metal enrichment was justified based on its high correlation with other heavy metals. The regression coefficients of metal/Fe came out to be significant for all the metals in both level and log versions. For the metals, where prediction exceeded upper 95% confidence interval, we mapped the site with factors such as number of industries located within …

The Business Dynamics In Telecommunication Market Consolidation, George Amstad

LSU Master's Theses

The Swiss telecommunication market is quite different from the markets in surrounding European countries. The Swiss Market is characterized by a very small number of competitors and relatively high and stable prices. The model in this thesis explains shows how the limited competition enables the mobile telecommunication service providers to keep prices up. This is due to a oligopoly market situation linked to complicated laws that discourage new competitors to join the Swiss market. Later in 2006, the Swiss federal council will pass the new televisor law, which will make it significantly easier to join the Swiss market. This will …

Design And Test Of A Displacement Workspace Mapping Station For Articular Joints, Michael Daly Guillet

LSU Master's Theses

In 2003, 267,000 Americans received total knee replacements prohibiting high impact athletics for the remainder of a patient’s life. A better understanding of the movement and constraint of the knee is necessary to provide more realistic motion of or possibly eliminate the need for joint prosthetics. Fixed Orientation Displacement Workspaces (FODW) can be applied to study the relationship of the passive constraint system and six (6) degree of freedom (DOF) movement of the human knee. A FODW consists of the volume of possible positions the tibia/fibula can occupy relative to a fixed femur without changing the relative orientation of the …

Dynamics Of An Atmospheric Pressure Plasma Plume Generated By Submicrosecond Voltage Pulses, Xinpei Lu, Mounir Laroussi

Electrical & Computer Engineering Faculty Publications

Nonequilibrium plasmas driven by submicrosecond high voltage pulses have been proven to produce high-energy electrons, which in turn lead to enhanced ionization and excitations. Here, we describe a device capable of launching a cold plasma plume in the surrounding air. This device, "the plasma pencil," is driven by few hundred nanosecond wide pulses at repetition rates of a few kilohertz. Correlation between current-voltage characteristics and fast photography shows that the plasma plume is in fact a small bulletlike volume of plasma traveling at unusually high velocities. A model based on photoionization is used to explain the propagation kinetics of the …

Bacteria Foraging: A New Tool For Simultaneous Robust Design Of Upfc Controllers, M. Tripathy, S. Mishra, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

Robust tuning of lead-lag type controller used for regulating FACTS control signal to improve dynamic stability has been an area of interest in research. This paper presents a new approach based on the foraging behavior of E. coli Bacteria in the human intestine, to optimize simultaneously three constants each of four lead-lag type UPFC controller present in a Single Machine Infinite Bus (SMIB) power system. For the tuning purpose, a multi-objective cost function is formulated that accounts for damping factors and ratios of various system modes for a wide range of operating conditions. Robustness of the proposed tuning method is …

Development And Implementation Of Optimized Energy-Delay Sub-Network Routing Protocol For Wireless Sensor Networks, Maciej Jan Zawodniok, Jagannathan Sarangapani, Steve Eugene Watkins, James W. Fonda

Electrical and Computer Engineering Faculty Research & Creative Works

The development and implementation of the optimized energy-delay sub-network routing (OEDSR) protocol for wireless sensor networks (WSN) is presented. This ondemand routing protocol minimizes a novel link cost factor which is defined using available energy, end-to-end (E2E) delay and distance from a node to the base station (BS), along with clustering, to effectively route information to the BS. Initially, the nodes are either in idle or sleep mode, but once an event is detected, the nodes near the event become active and start forming sub-networks. Formation of the inactive network into a sub-network saves energy because only a portion of …

Distributed Power Control For Cellular Networks In The Presence Of Channel Uncertainties, Maciej Jan Zawodniok, Q. Shang, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel distributed power control (DPC) scheme for cellular network in the presence of radio channel uncertainties such as path loss, shadowing, and Rayleigh fading is presented. Since these uncertainties can attenuate the received signal strength and can cause variations in the received Signal-to-Interference ratio (SIR), a new DPC scheme, which can estimate the slowly varying channel uncertainty, is proposed so that a target SIR at the receiver can be maintained. Further, the standard assumption of a constant interference during a link's power update used in other works in the literature is relaxed. A CDMA-based cellular network …

Internal Separation Of Powers: Checking Today's Most Dangerous Branch From Within, Neal K. Katyal

Georgetown Law Faculty Publications and Other Works

The standard conception of separation of powers presumes three branches with equivalent ambitions of maximizing their powers. Today, however, legislative abdication is the reigning modus operandi. Instead of bemoaning this state of affairs, this piece asks how separation of powers can be reflected within the Executive Branch when that branch, not the legislature, is making much law today. The first-best concept of legislature v. executive checks-and-balances has to be updated to contemplate second-best executive v. executive divisions.

A critical mechanism to promote internal separation of powers is bureaucracy. Much maligned by both the political left and right, bureaucracy serves crucial …

Online Training Of A Generalized Neuron With Particle Swarm Optimization, R. Kiran, Ganesh K. Venayagamoorthy, Sandhya R. Jetti

Electrical and Computer Engineering Faculty Research & Creative Works

Neural networks are used in a wide number of fields including signal and image processing, modeling and control and pattern recognition. Some of the most common type of neural networks is the multilayer perceptrons and the recurrent neural networks. Most of these networks consist of large number of neurons and hidden layers, which results in a longer training time. A Generalized Neuron (GN) has a compact structure and overcomes the problem of long training time. Due to its simple structure and lesser memory requirements, the GN is attractive for hardware implementations. This paper presents the online training of a GN …

Markets For Markets: Origins And Subjects Of Information Markets, Miriam A. Cherry, Robert L. Rogers

All Faculty Scholarship

This Article focuses on why information markets have covered certain subject areas, sometimes of minor importance, while neglecting other subject areas of greater significance. To put it another way, why do information markets exist to predict the outcome of the papal conclave and the Michael Jackson trial, but no information markets exist to predict government policy conclusions, Supreme Court decisions, or the rulings in Delaware corporate law cases? Arguably, from either a dollar value or a social utility perspective, these areas of law and business would be more important than the outcome of, say, the Jackson trial. Why, then, do …

Chemometric Analysis Of Multivariate Liquid Chromatography Data: Applications In Pharmacokinetics, Metabolomics, And Toxicology, Sarah Elizabeth Graham Porter

Theses and Dissertations

In the first part of this work, LC-MS data were used to calculate the in-vitro intrinsic clearances (CLint) for the metabolism of p-methoxyrnethamphetamine (PMMA) and fluoxetine by the CYP2D6 enzyme using a steady-state (SS) approach and a new general enzyme (GE) screening method. For PMMA, the SS experiment resulted in a CLint of 2.7 ± 0.2 µL pmol 2D6-1min-1 and the GE experiment resulted in a CLint of 3.0 ± 0.6 µL pmol 2D6-1min-1. For fluoxetine, the SS experiment resulted in a CLint of 0.33 ± 0.17 µL pmol 2D6-1min-1 and the GE experiment resulted in a CLint of 0.188 …

A Model To Predict 24-Hour Urinary Creatinine Level Using Repeated Measurements, Donna S. Kroos

Theses and Dissertations

Creatinine is a metabolic waste product, removed from the blood by the kidneys, and excreted in the urine. The measurement of creatinine is used in the assessment and monitoring of many medical conditions as well as in the determination or adjustment of absorbed dosage of pesticides. Earlier models to predict 24-hour urinary creatinine used ordinary least squares regression and assumed that the subjects' observations were uncorrelated. However, many of these studies had repeated creatinine measurements for each of their subjects. Repeated measures on the same subject frequently are correlated. Using data from the NIOSH-CDC "Pesticide Dose Monitoring in Turf Applicators" …

Forecasting Stability Levels For The Countries Of The Former Soviet Union, Margaret Erin Keck

Theses and Dissertations

United States intelligence officers and policymakers need reliable forecasts of country, regional, and global stability or instability. Such forecasts require a methodology for identifying and analyzing factors that contribute to stability. The anticipation of this stability level can facilitate crisis warning and diplomatic strategies for various timelines, including five, ten, and twenty year forecasts. While the problem of forecasting can be tackled in various ways, in the interest of time and space, I will only go into a few of them. The approach I will use is multiple linear regression to generate a short-term forecast for the stability levels of …

The Oldest Well, Saul Benjamin Becker

Theses and Dissertations

This body of work, representing the past two years, is focused on the idea of the composite landscape. This reconfiguring of the elements from the external world combined with invented places is a way for me to articulate the subtle transactions between the interior psyche and the external world. The way this new conglomerate space is represented is a result of my inquiry into the relationship between nature, culture, and the sublime. The place where the private acts of the studio meet the shared exterior world is where I find my intellect, fantasy, and sense of reality collaborating in chorus.

Silicon Oxide Nanoparticles Reveal The Origin Of Silicate Grains In Circumstellar Environments, Peneé Armaize Clayborne

Theses and Dissertations

The processes leading to the widespread presence of crystalline silicates throughout the galaxy and the origin of silicon nanoparticles thought to be responsible for the observed extended red emission in diffuse galactic background are still far from being understood. One of the most abundant oxygen bearing species in molecular astronomical regions is SiO. It has been conjectured that silicate formation probably proceeds via the agglomeration of these molecular species; however there are no studies to reveal the microscopic mechanism. We have used a synergistic approach combining experiments in molecular beams and first principles theoretical calculation to demonstrate that the passage …
