Development Of A True Triaxial Apparatus For Soil Testing, Heath Stuart Williams Jan 2004

Development Of A True Triaxial Apparatus For Soil Testing, Heath Stuart Williams

LSU Master's Theses

This thesis presents the development of a True Triaxial Testing TTT Apparatus. The TTT apparatus developed has the capabilities of applying the three principal stresses to a rectangular prismoidal specimen independently. The minor principal stress is provided by the cell pressure. The major principal stress is provided by a load actuator traveling at a constant velocity. A LabView software program instantaneously reads instrumentation, makes calculations, and commands a second load actuator to induce an intermediate principal stress that maintains a constant b-value; where b-value is equal to the intermediate principal stress minus the minor principal stress divided by the major …

Which Mean Do You Mean?: An Exposition On Means, Mabrouck K. Faradj Jan 2004

Which Mean Do You Mean?: An Exposition On Means, Mabrouck K. Faradj

LSU Master's Theses

The objective of this thesis is to give a brief exposition on the theory of means. In Greek mathematics, means are intermediate values between two extremes, while in modern mathematics, a mean is a measure of the central tendency for a set of numbers. We begin by exploring the origin of the antique means and list the classical means. Next, we present an overview of the theories of binary means and n-ary means. We include a general discussion on axiomatic systems for means and present theorems on properties that characterize the most common types of means.

Escalation Bias In Group Decision-Making, Molly Joann Russ Jan 2004

Escalation Bias In Group Decision-Making, Molly Joann Russ

LSU Master's Theses

The present study extended the literature on escalation bias to group decision-making in the context of performance appraisal. Escalation theory states that persons responsible for a hiring decision will provide higher evaluation ratings of that employee than those persons not responsible for the decision. This study compared the performance evaluation decisions of supervisors, individual team members, and teams in order to ascertain differences in escalation behaviors based on rater perspective and whether the rater was responsible for hiring the employee or not. Support for the hypotheses varied depending on the employment decision being made and the perspective of the decision-maker. …

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert Jan 2004

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert

LSU Master's Theses

Presently, effective cooling of modern low NOx combustor liners is achieved through combinations of innovative impingement configurations and other heat transfer enhancement methods. An inherent characteristic of conventional impingement configurations is the occurrence of downstream heat transfer degradation due to increased crossflow effects. In the present study, two different impingement configurations are studied. Both impingement configurations examined in this study aim to increase heat transfer effectiveness by reducing the detrimental effects of spent air crossflow. In Part I, a combination technique wherein impingement is combined with ribs placed in between impingement rows is studied. Three configurations with increased rib placements …

Mineral Utilization In Poultry As Affected By Virginiamycin Or Mineral Source, Tanika Ivel O'Connor-Dennie Jan 2004

Mineral Utilization In Poultry As Affected By Virginiamycin Or Mineral Source, Tanika Ivel O'Connor-Dennie

LSU Master's Theses

Four experiments were conducted to evaluate the effects of diets with reduced Ca or nonphytate P (nPP) levels with supplemental virginiamycin (Vm) on growth performance and bone response variables in chicks. All diets were corn-soybean meal based and all treatments were replicated six or eight times with five or six chicks each. Reducing dietary nPP from 0.45 to 0.15, 0.25, or 0.35% decreased most growth and bone response variables. The addition of Vm to diets containing 0.35% nPP and above increased both growth and bone response variables. The addition of Vm to diets containing 0.25% nPP and below had no …

"Never Could Read No Road Map": Geographic Perspectives On The Grateful Dead, Daniel R. Culli Jan 2004

"Never Could Read No Road Map": Geographic Perspectives On The Grateful Dead, Daniel R. Culli

LSU Master's Theses

The Grateful Dead hold a unique niche in the musical, social, and cultural history of the United States. However, while the volume of available academic literature concerning the band is increasing, the Grateful Dead remain to be nearly ignored by academia and, to this point apparently, completely ignored by cultural geographers. This paper introduces the Grateful Dead into the field of geography. I analyze the geography of certain aspects of the band, such as its context in San Francisco, the carnival atmosphere of the entire phenomenon, the over 2300 tour dates, as well as the huge catalog of lyrics sung …

Vie Et Mort De La Rhetorique Dans Le Conte Du Graal Ou Le Roman De Perceval, Oana Carmina Cimpean Jan 2004

Vie Et Mort De La Rhetorique Dans Le Conte Du Graal Ou Le Roman De Perceval, Oana Carmina Cimpean

LSU Master's Theses

This thesis illustrates the distinction established by Maurice Blanchot in Le Livre à venir, between novel and narration, as it appears in Chrétien de Troyes' Le conte du Graal ou le roman de Perceval. The novel accompanies the hero to the meeting with the Sirens, while the narration constitutes the meeting itself. Once the hero had his meeting with the Sirens, in Perceval's case he has the privilege of hearing God's names, he disappears from the novel, entering the realm of silence, which dominates the narration. In leaving the novel, Perceval gains access to a superior meaning, hidden to the …

Predicting Party Switching In U.S. State Legislatures, Dylan Scott Rickards Jan 2004

Predicting Party Switching In U.S. State Legislatures, Dylan Scott Rickards

LSU Master's Theses

Using a strategic politician model, I argue that we should be able to predict when legislators are going to switch parties by weighing the costs and benefits of party switching under different circumstances. Using variables that measure electoral risk and opportunities for advancement to higher office, an event history model is used to predict when individual legislators will switch. Although this is a rare occurrence, and electoral risk seems to play little in the decision to switch parties, we do find that opportunities for advancement and the relative power of the two parties (measured by offices held) has a noticeable …

Scalability Of Car-Following And Lane-Changing Models In Microscopic Traffic Simulation Systems, Yan Zhang Jan 2004

Scalability Of Car-Following And Lane-Changing Models In Microscopic Traffic Simulation Systems, Yan Zhang

LSU Master's Theses

Microscopic simulation models are more and more widely used to support real-time control and management functions in the field of transportation engineering. However, even with today¡¯s advancement in computing power, microscopic simulation modeling remains a computationally intensive process that imposes limitations on its potential use for modeling large-scale transportation networks. While microscopic features of a simulated system collectively define the overall system characteristics, it is argued here that the simulation process itself is not necessarily free of redundancy which, if reduced, could substantially improve the computational efficiency of simulation processes without substantially compromising the overall integrity of the simulation process. …

Minimum Dogma And Religious Toleration, Clinton Bryan Barron Jan 2004

Minimum Dogma And Religious Toleration, Clinton Bryan Barron

LSU Master's Theses

This thesis examines issues that emerge from the investigation of the relationship between John Locke's arguments for religious toleration as found in his Letter Concerning Toleration and his construction of a minimum dogma for Christianity in his The Reasonableness of Christianity. The first chapter follows the development of minimum dogma from its origin in the experience Eric Voegelin terms the leap in being, through Xenophanes' concept of "seemliness," to the minimum dogmas of Plato. The second chapter examines the use of minimum dogma in theories of religious toleration by More and Spinoza. The final chapter examines the work of John …

That Memorable Campaign: American Experiences In The China Relief Expedition During The 1900 Boxer Rebellion, Eric T. Smith Jan 2004

That Memorable Campaign: American Experiences In The China Relief Expedition During The 1900 Boxer Rebellion, Eric T. Smith

LSU Master's Theses

At the time of the Boxer Rebellion in China in 1900, the American army was not experienced in dealing with challenges abroad. The Army spent the last quarter of the nineteenth century fighting the Indian Wars in the West and a generation of officers grew to maturity commanding small frontier posts where only a few had the opportunity to maneuver large formations during the Spanish-American War. The infantrymen who marched into Peking in August of 1900 were transitioning between the tactics of the past and the future. The Napoleonic formations used in the American Civil War, already made obsolete at …
