Fault Discrimination Algorithm For Busbar Differential Protection Relaying Using Partial Operating Current Characteristics, Monir Hossain

LSU New Orleans Theses and Dissertations

Differential protection is the unit protection system which is applied to protect a particular unit of power systems. Unit is known as zone in protection terminology which is equivalent to simple electrical node. In recent time, low impedance current differential protection schemes based on percentage restrained characteristics are widely used in power systems to protect busbar systems. The main application issue of these schemes is mis-operation due to current transformer (CT) saturation during close-in external faults. Researchers have suggested various solution of this problem; however, individually they are not sufficient to puzzle out all mis-operational scenarios. This thesis presents a …

Electrical Power: Its Advent And Role In Revitalizing And Expanding New Orleans 1880-1915, John Schneller Iii

LSU New Orleans Theses and Dissertations

Abstract

New Orleans in 1900 was an endangered city clinging to a narrow strip of relatively high ground along the lower Mississippi river. Frequent flooding occurred from the river in the spring and from the lake in the June to October hurricane season. No reliable source of drinking water and no systems for removal of sewerage and rain water existed. Disease mortality was very high especially from frequent outbreaks of yellow fever.

The fortuitous appearance of new alternating current (AC) technologies, emerging engineering specialties, and a more progressive form of governance willing to support and finance large scale engineering projects …

Effect Of Small-Scale Continental Shelf Bathymetry On Storm Surge Generation, Sunni A. Siqueira

LSU New Orleans Theses and Dissertations

Idealized bathymetries were subjected to idealized cyclones in order to measure the storm surge response to a range of bathymetry features, under various storm conditions. Ten bathymetries were considered, including eight shoals, one pit, and a featureless reference domain. Six storms (two different sizes/intensities and three different landfall directions) were used as meteorological forcing. The bathymetry features influenced local surge response during pre- and post-peak surge conditions. However, peak surge and surge at the coast were not meaningfully affected by the presence of the bathymetry features considered. The effect of three bathymetry feature parameters on surge response was analyzed (i.e. …

A Machine Learning Approach To Determine Oyster Vessel Behavior, Devin Frey

LSU New Orleans Theses and Dissertations

A support vector machine (SVM) classifier was designed to replace a previous classifier which predicted oyster vessel behavior in the public oyster grounds of Louisiana. The SVM classifier predicts vessel behavior (docked, poling, fishing, or traveling) based on each vessel’s speed and either net speed or movement angle. The data from these vessels was recorded by a Vessel Monitoring System (VMS), and stored in a PostgreSQL database. The SVM classifier was written in Python, using the scikit-learn library, and was trained by using predictions from the previous classifier. Several validation and parameter optimization techniques were used to improve the SVM …

If It Feels Good, View It: Selective Exposure And Desensitization Moderate The Association Between Video Gameplay And Pleasure-Oriented Aggression, Mejdy M. Jabr

LSU New Orleans Theses and Dissertations

A number of studies have indicated that violent video gameplay is associated with higher levels of aggression, and desensitization to violent content contributes to this association. Utilizing a rapid serial visual presentation (RSVP) task, the current study used event-related potentials (ERPs) to investigate selective attention (N1 activation), cognitive control (N2 activation), and desensitization (P3 activation) as neurocognitive mechanisms potentially underlying the association between gameplay and subtypes of aggression. Results showed video game players and non-players differed significantly in brain activation when engaged with violent imagery. N1 and P3 amplitude moderated the association between gameplay and pleasure-oriented aggression. Follow-up analyses further …

Jill Jackson: Pioneering In The Press Box, Katherine C. Perkins

LSU New Orleans Theses and Dissertations

Jill Jackson was one of the first female sports journalists and a pioneer voice for women in athletics. Although heretofore overlooked in the history of American sports journalism, the story of her career is an addition not only to the historiography of female sports journalists but also to the broader study of women in the mid-twentieth century. Jackson was admired, a hard worker, from a prominent New Orleans family, and well educated, yet she still was treated unequally in her primary workspace—the press box. Jackson left well-documented story to the Nadine Vorhoff Library and Special Collections at Newcomb College Institute …

Brief Encounters, Alexandra E. Reisner

LSU New Orleans Theses and Dissertations

This collection of essays meditates on connection and how it is formed and severed. Several pieces consider lasting or arbitrary connections, like those holding together members of a family or the bridges joining two sides of a city. Some consider more tenuous bonds, such as the chance meeting of near-strangers or the moment shared between a child and a dying mouse. Indeed, many pieces consider the ways in which characters are bound to life – and to death.

Examination Of The Successful Psychopathy Conceptualization In Youth With Callous-Unemotional Traits, Tina D. Wall Myers

LSU New Orleans Theses and Dissertations

Although research has demonstrated that some adults with psychopathic traits show better executive functioning and higher intelligence that make them “successful”, there has been very minimal research testing whether similar distinctions can be made in samples of youth with elevated CU traits. Utilizing a sample of 1216 male adolescent first-time offenders, the current study examined whether executive functioning, intelligence and/or impulse control would moderate the relationship between CU traits and antisocial outcomes. The current study also examined whether CU traits were more strongly associated with a number of positive adjustment indicators at higher levels of the moderators. Results did not …

The New Normal? Climate Variability And Ecoviolence In Sub-Saharan Africa, Alfonso Sanchez

LSU New Orleans Theses and Dissertations

Climate change presents a wide range of concerns that can jeopardize international security. Among those concerns are neo-Malthusian worries of diminishing natural resources. Predictive models suggest that rainfall and temperature anomalies have the potential to reduce water basins, crop production, increase land degradation among other perils that threaten human security. This concern is particularly true in sub-Saharan Africa given the region’s strong dependence on rain-fed agriculture. Despite strong claims from various world leaders and scientists of a direct climate-conflict nexus, little empirical evidence has been devoted to find a systematic causal pathway of this kind. What is more, the literature …

Advocacy Coalition Formation, Mobilization, Sustainment, And Fragmentation: A Case Study Of The New Orleans Federal Alliance (Nofa) And The Federal City Project, Gerald J. Ormerod

LSU New Orleans Theses and Dissertations

U.S. military bases and installations represent trillions of dollars of capital investment towards the nation’s defense infrastructure. The Department of Defense, in its response to the end of the Cold War with the Soviet Union in the 1980s, sought to reorganize and optimize this basing infrastructure to meet the emerging threats of the 21^st century. A series of nationwide Base Realignment and Closure (BRAC) efforts were chartered by Congress to facilitate this task, identifying hundreds of obsolete or unneeded military installations. During the last BRAC effort in 2005, the Naval Support Activity New Orleans was targeted for closure, with …

Molecular Dynamics Simulations Of Stimuli-Responsive Polymers, Arjun Sharma

LSU New Orleans Theses and Dissertations

Polymers that undergo dramatic changes in structural conformations in response to numerous stimuli such as temperature, pH, electric and magnetic fields, light inten- sity, biological molecules, and solvent polarity, are known as stimuli-responsive or ”smart” polymers. There is a broad range of very promising applications of these materials in catalysis, environmental remediation, sensors or actuator systems, and as delivery systems of therapeutic agents. Researchers have been trying to mimic smart polymers based on properties of polymers found in nature such as proteins, carbohydrates and nucleic acids. Novel bio-compatible polymers with a variety of chemical functional groups, diverse topologies, and cross-linking …

Biloxi Marsh Platform Response Due To Meteorological Forcing, Rachelle Thomason

LSU New Orleans Theses and Dissertations

The Biloxi Marsh of the eastern Mississippi River delta plain is exposed to meteorological forces ranging from large-scale, mid-latitude cyclones to smaller scale storms and squalls. Each time that these marsh platforms are exposed to a storm event, the potential exists for either deposition or erosion to take place. This study examines the connection between wind speeds, stratigraphic composition, marsh edge morphology, and marsh edge erosion at 4 sites in the Biloxi Marsh. As much as 2.17 m of erosion were measured during the 9-month study with a maximum, averaged erosion rate of 0.03 m day^-1. Shell berm …

Territoriality And Spatial Structure In The Green Anole, Anolis Carolinensis, William D. Weber Jr.

LSU New Orleans Theses and Dissertations

Anolis carolinensis has been a model organism for ecology and evolutionary biology since the seventies, yet there are still understudied aspects of their ecology. A five-year study has provided microsatellite genotypes to be used in building a pedigree and assess relatedness, enabling us to evaluate the spatial distribution of an urban population of A. carolinensis. Results indicate no correlation between a male’s size and the distance others keep from it; however, males belonging in the heavyweight morph are dictating the spatial distribution in this population. In addition, juvenile dispersal of male offspring and partial philopatry of female offspring are …

Parenting Style And Adolescent Gender As Moderators Of The Association Between Parental Restrictions And Adolescents' Risky Driving, Megan M. Zeringue

LSU New Orleans Theses and Dissertations

Motor vehicle crashes are the leading cause of teenage deaths in the United States, highlighting the need for ways to reduce teenage driver crash rates. Adolescents (n = 176, M age = 16.4 years, 53% female) and their parents (n = 204, 71% mothers) self-reported on parenting style, driving restrictions, and risky driving. Results showed that more parental restrictions were associated with less adolescent risky driving. Three-way interactions were found such that more restrictions were associated with less concurrent risky driving in boys only under conditions of high parental warmth, structure, or autonomy support. Parenting style generally did …

Parents' Perceptions Regarding The Special Education Classification Of Other Health Impairment (Ohi), Michael C. Norman

LSU New Orleans Theses and Dissertations

Students identified by the special education classification Other Health Impairment (OHI) represent the third largest group of students receiving special education services in the United States. The special education services offered these students include both academic and health related supports. The delivery of these services is enhanced when a partnership exits between the primary stakeholders; the student, parents, the school personnel, and the medical personnel. The use of Family Centered Care principles in the delivery of these services supports and maintains the partnership.

Following the qualitative analysis of a series of interviews of parents whose children were classified as OHI, …

Anxiety And Differences In Physiological Responding To Ambiguous Situational Vignettes In Adolescents, Donice M. Banks

LSU New Orleans Theses and Dissertations

Research has documented a tendency among youth to have biased interpretations of ambiguous information. For example, anxious youth are more likely to interpret ambiguous situations as negative or threatening (e.g., Cannon & Weems, 2010). Similarly, when interpreting social cues, aggressive youth exhibit hostile attribution biases more often than non-aggressive youth in response to ambiguous situations (e.g., Crick & Dodge, 1996). Research suggests that youth with anxiety and aggression exhibit differential physiological reactivity in response to threat. However, research has yet to examine the linkages amongst physiological reactivity to ambiguous situations, anxiety, and aggression in adolescents. The current study had several …

An Investigation Into The Origin, Composition, And Commercial Significance Of A Sedimentary Subsalt Formation: Keathley Canyon, Gulf Of Mexico, David Aaron Brassieur

LSU New Orleans Theses and Dissertations

Sub-salt oil and gas formations in deep-water northern Gulf of Mexico are high priority targets. Advances in seismic processing allow for high-resolution, below-salt imaging. Understanding the modes of salt emplacement provide insight into sub-salt traps and potential drilling hazards.

A sub-salt sedimentary unit lies in the Keathley Canyon protraction. Autosutures created the transport-parallel lineaments of the upper surface of the unit. In addition, highly variable sediment aggradation rates created ramps, flats, and basal cutoffs along the base of the allochthon as salt and sediment competed for space. Seismic models identify modes of salt emplacement, salt/sediment interactions, and mechanisms responsible for …

Optimal Dg Placement: A Multimethod Analysis, Saiful A. Ratul

LSU New Orleans Theses and Dissertations

With Power System being restructured in the vision of Smart Grid, it is important now more than ever to find suitable locations to place Distributed Generators (DG). Distributed generators, which may be renewable, are not limited to specific locations as in the case of conventional generators. Several papers have been published that make suggestions on where the optimal location of DG should be in a system. Objectives ranging from loss minimization to total cost minimization have been the factor for such studies. In this study, a new method is introduced that hopes to improve a current system in three ways …

Spatial Data Mining Analytical Environment For Large Scale Geospatial Data, Zhao Yang

LSU New Orleans Theses and Dissertations

Nowadays, many applications are continuously generating large-scale geospatial data. Vehicle GPS tracking data, aerial surveillance drones, LiDAR (Light Detection and Ranging), world-wide spatial networks, and high resolution optical or Synthetic Aperture Radar imagery data all generate a huge amount of geospatial data. However, as data collection increases our ability to process this large-scale geospatial data in a flexible fashion is still limited. We propose a framework for processing and analyzing large-scale geospatial and environmental data using a “Big Data” infrastructure. Existing Big Data solutions do not include a specific mechanism to analyze large-scale geospatial data. In this work, we extend …

Factors Affecting Algal Biomass Growth And Cell Wall Destruction, Alicia E. Simosa

LSU New Orleans Theses and Dissertations

Research using microalgae Chlorella vulgaris was conducted in order to determine the maximum CO₂ concentration under which algae can grow, within the emission range from oil and natural gas burning plants (0-20%).

After choosing the optimal CO₂ percentage, pH and alkalinity were determined; and finally, an electrochemical (EC) batch reactor connected to DC current was applied to achieve algae cell annihilation, and therefore, facilitate anaerobic digestion, methane production and energy recovery.

It was determined that algae can grow under 20% CO_2, being 15% CO₂ the most effective (pH of 6.64 and alkalinity of 617.5 mg/L CaCO …

If Only They Tried; The Complicated Crusade For Salvation In The Post-Katrina Education Reform Movement, Brooke Wanamaker

LSU New Orleans Theses and Dissertations

Education reform is shifting the landscape of New Orleans public schools, where alternative certification programs are thriving and changing the demographics of core teachers. This study follows a Teach for America (TFA) Corps Member from 2007 (just after the historic flooding from Hurricane Katrina) who brought a promise of innovation through idealism and green wisdom. The teacher’s preparation and motivations are shown to be problematic. Examining the assumptions and privileges that underlie the import of inexperienced talent to urban education systems, this study considers the ways that community voices have been lost or undervalued in New Orleans schools. The thesis …
