Microfabrication Of Conductive Polymer Nanocomposite For Sensor Applications, Chaoxuan Liu

LSU Doctoral Dissertations

This dissertation developed novel microfabrication techniques of conductive polymer nanocomposite and utilized this material as a functional element for various physical sensor applications. Microstructures of nanocomposite were realized through novel microcontact printing and laser ablation assisted micropatterning processes. Prototype devices including large-strain strain sensor and highly-sensitive pressure sensor were demonstrated showing distinct advantages over existing technologies. The polymer nanocomposite used in this work comprised elastomer poly(dimexylsiloxane) (PDMS) as polymer matrix and multi-walled carbon nananotubes (MWCNTs) as a conductive nanofiller. To achieve uniform distribution of carbon nanotubes within the polymer, an optimized dispersion process was developed, featuring a strong organic solvent—chloroform, …

Examination Of The Reliability And Validity Of A New Observation Measure For Autism Spectrum Disorders: The Autism Spectrum Disorder Observation For Children, Daniene Neal

LSU Doctoral Dissertations

With increasing attention being drawn to autism spectrum disorders (ASD), specifically with regard to early and accurate diagnosis and treatment, researchers and clinicians alike have placed emphasis on finding assessment tools that can aid in this goal. The purpose of this study is to examine the psychometric properties of a new observation measure for ASD, the Autism Spectrum Disorders-Observation for Children (ASD-OC). The ASD-OC was found to have good to excellent interrater reliability, and excellent internal consistency (ƒÑ = .96). As a result of these initial reliability analyses, nine items were removed from the scale. The resulting 45 item ASD-OC …

Factors Affecting Short-Term Oxygen Variability In The Northern Gulf Of Mexico Hypoxic Zone, Brenda Leroux Babin

LSU Doctoral Dissertations

Open-water continuous monitoring of DO concentrations at a single station (C6) in the Gulf of Mexico from 1989 to 2008 afforded an excellent opportunity to characterize short-term oxygen variability and to estimate the relative importance of key physical and biological factors controlling the development, persistence, and dissipation of hypoxia. I investigated temporal trends in three aspects of short-term DO variability: respiration rates (i.e., how quickly bottom waters become hypoxic), persistence of hypoxia, and the dissipation of hypoxia (i.e., re-aeration events). I identified the range of respiration rates present at the study site, and showed how these rates vary throughout the …

The Article Ii Safeguards Of Federal Jurisdiction, Tara Leigh Grove

Articles

Jurisdiction stripping has long been treated as a battle between Congress and the federal judiciary Scholars have thus overlooked the important and surprising role that the executive branch has played in these jurisdictional struggles I seek to fill that void Drawing on two strands of social science research I argue that the executive branch has a strong incentive to use its constitutional authority over the enactment and enforcement of federal law to oppose jurisdictionstripping measures Notably this structural argument has considerable historical support The executive branch has repeatedly opposed jurisdictionstripping proposals in Congress That has been true even when the …

Early Voting In The 2004 Presidential Election, James Michael Siira

LSU Doctoral Dissertations

The addition of early voting laws has led to the many changes in the US political system. In this dissertation I examine early voting early voting in a number of different contexts. First, how early voting fits in with the larger issue of voter turnout in the U.S. Second, why some states have early voting policies and other states choose to not have those policies. Third, how state-level political parties view the option to cast an early vote. Fourth, the differences between early voters, election day voters, and non-voters. Fifth, what are the determents of casting an early ballot. Sixth, …

Strategies For Real Time Reservoir Management, Yuanyuan Shuai

LSU Doctoral Dissertations

Real–time reservoir management is developed to manage a shrinking labor force and rising demand on energy supply. This dissertation seeks good strategies for real–time reservoir management. First, two simulator–independent optimization algorithms are investigated: ensemble–based optimization (EnOpt) and bound optimization by quadratic approximation (BOBYQA). Multiscale regularization is applied to both to find appropriate frequencies for well control adjustment. Second, two gathered EnKF methods are proposed to save computational cost and reduce sampling error: gathered EnKF with a fixed gather size and adaptively gathered EnKF. Finally, oil price uncertainty is forecasted and quantified with three price forecasting models: conventional forecasting, bootstrap forecasting …

The Fractal Geometry Of Invention, Alan L. Durham

Articles

Fractals are geometric objects of inexhaustible detail. Fractal structures have been found in the contours of mountain ranges, the patterns of veins on a leaf, and the fluctuations of the Dow Jones Industrial Average. The endeavor of inventing new technologies, consisting of a hierarchical network of practical inquiries, exhibits fractal properties as well. Among these are multiplicity, latency, and self-similarity. Multiplicity means that a single inventive idea may lead to an immense and diverse array of technological artifacts. Latency means that the potential of an inventive idea to yield practical embodiments only reveals itself in time, and may never be …

Hypercube Diagrams For Knots, Links, And Knotted Tori, Ben Mccarty

LSU Doctoral Dissertations

For a knot K the cube number is a knot invariant defined to be the smallest n for which there is a cube diagram of size n for K. Examples of knots for which the cube number detects chirality are presented. There is also a Legendrian version of this invariant called the Legendrian cube number. We will show that the Legendrian cube number distinguishes the Legendrian left hand torus knots with maximal Thurston-Bennequin number and maximal rotation number from the Legendrian left hand torus knots with maximal Thurston-Bennequin number and minimal rotation number. Finally, there is a generalization of cube …

Republican Virtue And Expert Discourse: A Response To Professor Rana Commentary: National Security: Response, Luke Herrine, Joseph Maguilies

Articles

In this Article, the authors note their agreement with Professor Rana's historical analysis of a major change in national security discourse and elaborate on their disagreement with his account of the theoretical underpinnings of this transition. They locate their difference on the line between liberal and republican theory, arguing that the historical shift is from democratic republicanism to aristocratic republicanism and not, as Rana suggests, between Lockean liberalism and Hobbesean authoritarianism. After establishing this theoretical framework, the authors draw out some of the implications of their account. They emphasize the role of practical reasoning, explore the differences in how aristocratic …

Online Reviews And Consumers' Willingness To Pay: The Role Of Uncertainty, Yinglu Wu

LSU Doctoral Dissertations

Empirical studies of online reviews have found that valence (average rating) has a consistently positive impact on consumers’ willingness to pay (WTP), but volume does not. Although two studies tried to explain this phenomenon using different perspectives (Wu and Ayala, 2012; Sun, 2012), neither study can fully accommodate the consumer behaviors observed by the other. This dissertation adopts a theoretical framework that can explain the consumer behaviors observed in both studies as well as the varying influence of review volume at the individual level. Specifically, several studies were conducted to investigate the relationship between bidirectional online seller reviews (e.g., the …

An Investigation Into The Moderating Role Of Fear Appeals On The Relationship Between Regulatory Fit And Persuasion, Nam Young Kim

LSU Doctoral Dissertations

As one of the ways to persuade young people effectively, several scholars have indicated that using a tailored message that is consistent with individuals’ concerns and interests can influence their attitude and behavioral changes. Among diverse tactics to construct tailored health-messages, this research especially paid attention to individuals’ motivational goals (i.e., regulatory focus) that make them more inclined to a certain outcome. While promotion-oriented individuals primarily focus on how to achieve a desired ending, prevention-oriented individuals mainly focus on avoiding undesirable outcomes (Higgins, 1997; Higgins et al., 2001). Although numerous studies support the positive effects of the congruency between regulatory …

Analyzing Levels Of Feedback Delivered By Cooperating Teachers And Supervisors In A Teacher Internship: A Case Study, James Badger

Georgia Educational Researcher

This research analyzed the feedback delivered by cooperating teachers and university supervisors in an internship, and reports how student teachers perceived the feedback they received during debriefing sessions with their mentors. Hattie and Timperley’s (2007) framework for conceptualizing effective feedback was used to analyze cooperating teachers’ and field supervisor’ assessment of the student teachers’ classroom instruction. Findings from two surveys, documents, and interviews revealed a preponderance of feedback that was devoted to instruction and classroom management with a relative paucity of feedback dedicated to the processing of instruction, consideration of student learning, and development of self-reflection in the student teachers. …

The Far Field Transformation For The Antenna Modeling Based On Spherical Electric Field Measurements, P. Li, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

According to the uniqueness theorem, the far field radiation pattern of radiators such as antennas can be determined from the measured tangential electric or magnetic field components over an arbitrary Huygens' surface enclosing the radiator. In this paper, a method using the spherical electric field measurement is developed to calculate the far field radiation. Following the Schelkunoff's field equivalence principle, a spherical region surrounding the radiator is assumed and its internal space is filled up with the perfect electric conductor (PEC). The radiated field from the Huygens' equivalent electric current is zero. Referring to the Ohm-Rayleigh method and the scattering …

Development Of A Modular Dual Engine Hybrid Electric Vehicle Simulation Model, Kenan Baltaci

Dissertations and Theses @ UNI

Depleting resources of fossil fuel, climate change impacts, high oil prices, and strict emission requirements are leading to the research on efficient, environmentally friendly, and lowered fossil fuel dependent solutions in the transportation field. While a number of studies used computer modeling and simulation tools to investigate hybrid electric vehicles (HEVs), very few attempted to model and simulate a dual-engine hybrid vehicle. Designing a vehicle engine to meet energy needs in the fully loaded condition is not an optimal solution for manufacturers and customers. The larger the engine, the higher the manufacturing costs for companies, and higher fuel consumption for …

Magnetic Compensation In The Bimetallic Oxalates And The Cerium Volume Collapse, Peter Leo Reis

LSU Doctoral Dissertations

In this thesis the author reports his collaborative efforts on two distinct areas of research that has been conducted. The first part of the thesis pertains to the author and his collaborators research on a particular class of organic magnets called the bimetallic oxalates. The main theme of this research was to predict magnetic compensation (magnetization reversal) in unsynthesized bimetallic oxalate structures, motivated by experiments which showed that Fe(II)Fe(III) exhibited magnetic compensation. In addition it was known that a large amount of anisotropy was present in the bimetallic oxalate structure which resulted from the intermediate oxalate molecules between the transition …

Investigation Of Electroosmotic Flow Dynamics And Reproducibility In Capillary Electrophoresis, Funda Kizilkaya

LSU Doctoral Dissertations

The goal of this dissertation is to investigate electroosmotic flow (EOF) and electric field dynamics during capillary electrophoresis (CE) experiments using methods based on periodic photobleaching of fluorophores added to the separation buffer at nanomolar concentrations. The methods provide time resolved EOF and local electric field information during an experiment, which can be applied to fundamental studies to provide better understanding of CE techniques. The potential of the EOF monitoring method to improve CE migration reproducibility was investigated in Chapter 2. The EOF monitoring method and four other methods from the literature were applied to the same electrophoretic separations, and …

C0 Interior Penalty Methods For Cahn-Hilliard Equations, Shiyuan Gu

LSU Doctoral Dissertations

In this work we study C0 interior penalty methods for Cahn-Hilliard equations. In Chapter 1 we introduce Cahn-Hilliard equations and the time discretization that leads to linear fourth order boundary value problems. In Chapter 2 we review related fundamentals of finite element methods and multigrid methods. In Chapter 3 we formulate the discrete problems for linear fourth order boundary value problems with the boundary conditions of the Cahn-Hilliard type, which are called C0 interior penalty methods, and we carry out the convergence analysis. In Chapter 4 we consider multigrid methods for the C0 interior penalty methods. We present two smoothing …
