Increasing The Efficiency Of Network Interface Card, Amit Uppal

Theses and Dissertations

A Network Interface Card (NIC) is used for receiving the packets, processing the packets, passing the packets to the host processor, and sending the packets to other computers in a network. NIC uses the buffer management algorithm to distribute the buffer space among different applications. An application may use User Datagram Protocol (UDP) or Transmission Control Protocol (TCP), depending upon the type of application. Buffer Management Algorithm for UDP-based applications may be completely different from the one for TCP applications, since in UDP- based applications receiver do not send acknowledgement back to the sender. This thesis proposes two buffer management …

Comparing The Performance Of Heterogeneous And Homogeneous Swarms, Jason Alexander Hales

Theses and Dissertations

This thesis compares the performance of heterogeneous and homogenous swarms. Swarms are defined as particles or agents which react to their environment and fellow particles or agents according to social rules. The weights of three attributes of an individual agent were varied for these experiments: Collision Avoidance with individual agents in the swarm, Center of Mass of the swarm and the parameter that controls Velocity Matching in the swarm. In homogenous swarms, all individuals had the same attribute weights while in heterogeneous swarms weights for one attribute were taken from a normal distribution for the population. These swarms were then …

A Taxonomy Based Assessment Methodology For Small And Medium Size Manufacturers, Clayton Thomas Walden

Theses and Dissertations

The need for small and medium size manufacturing enterprises (SMEs) to have access to unbiased advice on best practices and related improvement approaches has been well established. However, this need was not found addressed very effectively in the research literature. Current practice is consultants peddling assessment tools which have the veneer of objectivity, but in reality only highlight the need to purchase their canned solutions. In response, this research attempts to synthesize previous research results and other published assessment methodologies into a taxonomy based assessment methodology (TBAM) which targets the delivery of focused recommendations which target improved performance of the …

A Periodic Technique For Measuring Thermal Properties Of Thin Samples, Garrett May

LSU New Orleans Theses and Dissertations

We present a periodic technique for measuring the thermal conductivity and diffusivity of thin samples simultaneously. In samples of this type, temperature measurements must be made across the sample faces and are therefore subject to large error due to the interface resistance between the temperature sensor and the sample. The technique uses measurements of the amplitude and phase of the periodic temperature across both a reference sample and the unknown material at several different frequencies. Modeling of the heat flow in the sample allows the simultaneous determination of the thermal parameters of the sample as well as the interface resistance. …

Microstructural Investigations Of The Layered Cathode Materials Licoo2 And Lini1/3mn1/3co1/3o2, Tanghong Yi

LSU New Orleans Theses and Dissertations

Both LiCoO2 and LiNi1/3Mn1/3Co1/3O2 layered cathode materials are investigated in our studies. P3 phase of CoO2, the end member of the LixCoO2, is found in both chemically and electrochemically delithiated materials. Delithiated LixCoO2 specimens decompose into fine Co3O4 and LiCoO2 particles starting at around 200 °C. This decomposing reaction is proved by in-situ X-ray diffraction and in-situ transmission electron microscopy investigations. The structures of pristine and cycled LiNi1/3Mn1/3Co1/3O2 are investigated by electron diffraction. Single and polycrystalline crystals are found in this material. The partial substitution of Co by Ni and Mn in LiNi1/3Mn1/3Co1/3O2 opens up the possibility of different cation …

An Investigation Of Factors Identified By Novice Teachers That Influence Performance On Standardized Assessments And Teacher Performance, Donna Odom Lacaze

LSU New Orleans Theses and Dissertations

Entry in the teaching profession is often dependent on a number of steps or phases involving standardized assessments and performance assessments. The relationships between and among the variables incorporated in such instruments are typically assumed, but not necessarily substantiated. Furthermore, the relationships between the variables assessed and factors involved in teacher preparation have not been investigated. This study was designed to investigate the nature of such relationships in one particular case. In the spring of 1997, the Louisiana legislature changed the Louisiana Teacher Assessment Program to create the Louisiana Teacher Assistance and Assessment Program (LaTAAP). LaTAAP is a uniform statewide …

Adjuvant Effects On Herbicide Absorption And Translocation, Darrin Matthew Dodds

Theses and Dissertations

Bispyribac-sodium is an acetolactate synthase (ALS) inhibiting herbicide introduced for control of grasses, broadleaves, and sedges in rice and turf. However, Mississippi and Arkansas rice producers have reported inconsistent barnyardgrass (Echinochloa crus-galli Beauv.) control with bispyribac-sodium. Experiments were conducted to determine if inconsistent barnyardgrass control with bispyribac-sodium could be alleviated through adjuvant technology. Absorption of 14C-bispyribac-sodium was greatest with a proprietary blend of methylated seed oil/organosilicone (MSO/OSL) (0.37 L ha-1) plus urea ammonium nitrate (UAN) (2% v/v) and the proprietary blend of MSO/OSL/UAN (2% v/v) at 80 and 74% of applied 14C-bispyribac-sodium, respectively. The addition of 32% UAN to MSO/OSL …

The Impact Of Louisiana Intech Professional Development On Elementary School Leaders' Perceptions Of Change And Student Achievement, Sheryl Abshire

LSU New Orleans Theses and Dissertations

Each year, hundreds of Louisiana's teachers participate in state-sponsored Integration of Technology (INTECH) training. Although INTECH training and certification is acknowledged by the Louisiana Department of Education as the standard for technology-trained teachers, no research has been conducted to determine its impact on student achievement (Picard, 2000). The study's purposes were to examine perceptions of school leaders about Louisiana INTECH professional development as a change agent in schools and to determine the impact of this training on third grade mathematics and reading achievement. This study addressed the questions: Do elementary school leaders perceive INTECH professional development as a catalyst for …

Exploring The Assessment Aspect Of Differentiated Instruction: College Efl Learners' Perspectives On Tiered Performance Tasks, Yeh-Uh Hsueh Chen

LSU New Orleans Theses and Dissertations

If human beings are believed to be individually unique, why are students evaluated with standardized tests? Differentiated instruction, honoring individual differences of each learner, provides an alternative answer to the question by employing tiered performance tasks to address personal needs in assessment situations. To explore the applicability of differentiated instruction in an English as a Foreign Language (EFL) environment, this case study explored Taiwanese college students’ perspectives on tiered performance tasks and educational implications of the perspectives with regard to EFL learning and teaching at the tertiary level. Grounded in the humanistic stance of education and sociocultural view of learning, …

The probes were based on FRET interactions between quantum dots that serve as …

Merging Identities: A Glimpse Into The World Of Albert Wicker, An African American Leader In New Orleans, 1893-1928, Melissa Lee Smith

LSU New Orleans Theses and Dissertations

The life and career of Albert Wicker, Jr. (1869-1928), reflects the growth of the new urban African-American middle class in New Orleans, Louisiana, in the early years of the twentieth century. He spent his career working for advances in education while using memberships in churches, Masonic groups, insurance companies, benevolent societies, and educational leagues to achieve his personal and professional goals. The networks created by him and others along the way illustrate not only complexity of black life in New Orleans but also the growing tendency of differing ethnic groups to work together to achieve common economic, political, social objectives.

Interactions Of The Striatal Gene Rhes With The Dopaminergic System In Rodents, Gabriel Quintero

LSU New Orleans Theses and Dissertations

Mice that are incapable of expressing the small G protein Rhes have been generated and have shown to have abnormalities in behaviors mediated by the striatum, a region in which Rhes is highly expressed. Moreover, conditions that result in dopamine supersensitivity and a breakdown in D1/D2 synergism in rodents, consistently decrease rhes mRNA in striatum. Thus, Rhes may play have relevance in dopamine signal modulation. For evaluating the role of Rhes in anxiety, stereotypy and basal motor activity, adult male and female wild-type (WT) mice, Rhes knockout (KO) mice, and mice heterozygous for the KO and WT alleles (Het) were …

Sandra Day O'Connor: Moderate Or Something More?, Patricia Arceneaux

LSU New Orleans Theses and Dissertations

In 2006 an historic era of the Supreme Court came to a close with the retirement of its first female justice, Sandra Day O'Connor. This paper attempts to expand judicial behavior scholarship by examining O'Connor's policy preferences for possible ideological change during her twenty-five year tenure on the Court. Average liberalism scores for her overall and civil rights/civil liberties issue area votes show an increase in liberalism over time. The researcher employs time series cross section analysis with panel corrected standard errors to determine factors responsible for this increase. Issue change, interagreement with the other justices, changes in Court membership, …

When Decision Meets Estimation: Theory And Applications, Ming Yang

LSU New Orleans Theses and Dissertations

In many practical problems, both decision and estimation are involved. This dissertation intends to study the relationship between decision and estimation in these problems, so that more accurate inference methods can be developed. Hybrid estimation is an important formulation that deals with state estimation and model structure identification simultaneously. Multiple-model (MM) methods are the most widelyused tool for hybrid estimation. A novel approach to predict the Internet end-to-end delay using MM methods is proposed. Based on preliminary analysis of the collected end-to-end delay data, we propose an off-line model set design procedure using vector quantization (VQ) and short-term time series …

The Village Of River Ranch: A Post Occupancy Evaluation Of A Traditional Neighborhood Development In Lafayette, Louisiana, Elizabeth A. Tomlinson

LSU New Orleans Theses and Dissertations

The proponents of New Urbanism claim the neighborhoods they design, called Traditional Neighborhood Developments (TNDs), promote community, sense of place, physical health, and environmental sustainability. Critics assert that community is stressed at the expense of individuality, that design unity has become rigid uniformity, and that the neighborhoods are orchestrated and do not reflect real life. This thesis, a post occupancy evaluation (POE), examines how one TND works for its residents and whether it accomplishes the goals of the architect/planner. An additional, essential purpose of this POE is to serve the "feed-forward" role of informing future neighborhood planning projects. The Village …

Public housing in the United States has been a controversial sociopolitical topic since the years of the Great Depression. The issue of appropriate and secure habitation for the country's "deserving poor" continues to be of great importance as government subsidies become scarce in the early 21st century. This dearth of support for public housing is even more evident and prominent along the United States-Mexico border of South Texas, a territory described as having a third world environment. The dissertation is a narrative history of public housing in Laredo, Texas, a border community. Compiled from news media records and the archives …

Non-Equilibrium Surface Growth For Competitive Growth Models And Applications To Conservative Parallel Discrete Event Simulations, Poonam Santosh Verma

Theses and Dissertations

Non-equilibrium surface growth for competitive growth models in (1+1) dimensions, particularly mixing random deposition (RD) with correlated growth process which occur with probability $p$ are studied. The composite mixtures are found to be in the universality class of the correlated growth process, and a nonuniversal exponent $\delta$ is identified in the scaling in $p$. The only effects of the RD admixture are dilations of the time and height scales which result in a slowdown of the dynamics of building up the correlations. The bulk morphology is taken into account and is reflected in the surface roughening, as well as the …

Lb_Migrate: A Dynamic Load Balancing Library For Scientific Applications, Rohit Kailash Chaube

Theses and Dissertations

Parallel and distributed environments are used to solve large scientific and engineering problems that often are irregular and data parallel. However, performance of many parallel applications is affected by computation overheads, communication time and load imbalance. Among these factors, load imbalance is caused by the irregular nature of the problem, its algorithm, the difference in processor characteristics, and runtime loads. A number of applications achieve load balancing by one-time assignment of task. However, a number of applications have workloads that are unpredictable, and vary over the course of their execution. For such type of applications, load balancing is achieved by …
