Implementation Of Separable & Steerable Gaussian Smoothers On An Fpga, Arjun Joginipelly Dec 2010

Implementation Of Separable & Steerable Gaussian Smoothers On An Fpga, Arjun Joginipelly

LSU New Orleans Theses and Dissertations

Smoothing filters have been extensively used for noise removal and image restoration. Directional filters are widely used in computer vision and image processing tasks such as motion analysis, edge detection, line parameter estimation and texture analysis. It is practically impossible to tune the filters to all possible positions and orientations in real time due to huge computation requirement. The efficient way is to design a few basis filters, and express the output of a directional filter as a weighted sum of the basis filter outputs. Directional filters having these properties are called "Steerable Filters." This thesis work emphasis is on …

Highly Sensitive And Selective Gas Sensors Based On Vertically Aligned Metal Oxide Nanowire Arrays, Jiajun Chen Dec 2010

Highly Sensitive And Selective Gas Sensors Based On Vertically Aligned Metal Oxide Nanowire Arrays, Jiajun Chen

LSU New Orleans Theses and Dissertations

Mimicking the biological olfactory systems that consist of olfactory receptor arrays with large surface area and massively-diversified chemical reactivity, three dimensional (3D) metal oxide nanowire arrays were used as the active materials for gas detection. Metal oxide nanowire arrays share similar 3D structures as the array of mammal's olfactory receptors and the chemical reactivity of nanowire array can be modified by surface coatings. In this dissertation, two standalone gas sensors based on metal oxide nanowire arrays prepared by microfabrication and in-situ micromanipulation, respectively, have been demonstrated. The sensors based on WO3 nanowire arrays can detect 50 ppb NO2 with a …

Understanding Bullying Participant Roles: Stability Across School Years And Personality And Behavioral Correlates, Ann Crapanzano Dec 2010

Understanding Bullying Participant Roles: Stability Across School Years And Personality And Behavioral Correlates, Ann Crapanzano

LSU New Orleans Theses and Dissertations

This study investigated the factorial validity, stability, and social, behavioral and emotional correlates of several different roles that students can play in the context of bullying. Data were collected from students at two time points across two school years, April and May of 2006 (n=284) and again in November and December of 2006 (n=185). A confirmatory factor analysis provided evidence for the validity of 4 participant roles (i.e. bully, reinforcer, assistant, and defender). However, further analysis revealed that there was a strong degree of intercorrelation between the three bully factors (i.e., bully, reinforcer, and assistant). Analyses found that participant roles …

The Making Of Audubon Park: Competing Ideologies For Public Space, Nels Abrams Dec 2010

The Making Of Audubon Park: Competing Ideologies For Public Space, Nels Abrams

LSU New Orleans Theses and Dissertations

The emergence of Progressivism at the beginning of the twentieth century influenced many aspects of American society. One of those aspects was urban parks. In the latter half of the nineteenth century Frederick Law Olmsted led a nationwide implementation of "Victorian" parks. These parks featured broad expanses of turf, waterways, and trees. Olmsted and the other Victorian park leaders designed the parks to cultivate Victorian values of self-restraint and independence among the citizenry. With the rise of Progressivism the ideals of the middle class changed. Led by Theodore Roosevelt, millions of Americans embraced the "strenuous life" and its emphasis on …

Barely There Tales: A Phenomenological Study Of Stories Told By Pre-Service Teachers, Cynthia Ybos Dec 2010

Barely There Tales: A Phenomenological Study Of Stories Told By Pre-Service Teachers, Cynthia Ybos

LSU New Orleans Theses and Dissertations

Teacher stories were once relegated to informal gatherings but more recently this aspect of teacher development is being carefully studied in more formalized settings because it is believed to be an important part of teacher development. New ways are being sought to use various aspects of storytelling to help pre-service teachers develop important teaching skills through reflection on experience, dialogue journals, case studies and autobiography. Despite these efforts at the university level, it is especially difficult for pre-service teachers to integrate and apply theories from their methods courses to actual classroom practice. Less effort has been focused on storytelling processes …

Albert Baldwin Wood, The Screw Pump, And The Modernization Of New Orleans, Nicole Romagossa Dec 2010

Albert Baldwin Wood, The Screw Pump, And The Modernization Of New Orleans, Nicole Romagossa

LSU New Orleans Theses and Dissertations

Albert Baldwin Wood and his screw pumps modernized New Orleans by bringing flood-free streets and cleaner water to the city while providing the potential for growth by pumping swamp lands dry. While Wood was never part of the local Progressive movement, his work with the pumps fit with Progressive initiatives for modernization. At first, the screw pumps removed rain water from the streets. Then New Orleans expanded the drainage to include sewerage removal and water purification. The pumps successfully drained thousands of acres of land once considered uninhabitable swamp land. This additional land extended New Orleans city limits but also …

The Effects Of Rhes On Opioid Analgesia, Franklin Lee Dec 2010

The Effects Of Rhes On Opioid Analgesia, Franklin Lee

LSU New Orleans Theses and Dissertations

Rhes (Ras homolog enriched in striatum) has been identified as a novel monomeric G-protein involved in dopaminergic and other signaling in the striatum. Given the many effects of opioids that involve striatal circuitry, genetically engineered mice that are incapable of making Rhes (rhes-/-) and their control littermates (rhes+/+) were subjected to behavioral tests to determine if any differences existed in opioid analgesia, tolerance, withdrawal, reward, and locomotion. Rhes-/- mice showed an increased opioid mediated analgesia, along with an absence of tolerance and decrease in withdrawal when compared with rhes+/+ littermates. However, no significant changes were seen in opioid induced locomotor …

Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar Dec 2010

Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar

LSU New Orleans Theses and Dissertations

In digital forensics, source camera identification of digital images has drawn attention in recent years. An image does contain information of its camera and/or editing software somewhere in it. But the interest of this research is to find manufacturers (henceforth will be called make and model) of a camera using only the header information, such as quantization table and huffman table, of the JPEG encoding. Having done research on around 110, 000 images, we reached to state that "For all practical purposes, using quantization and huffman tables alone to predict a camera make and model isn't a viable approach". We …

Spiral Welded Pipe Piles For Structures In Southeastern Louisiana, Leeland Richard Dec 2010

Spiral Welded Pipe Piles For Structures In Southeastern Louisiana, Leeland Richard

LSU New Orleans Theses and Dissertations

In an effort to obtain 100-year level hurricane protection for southeastern Louisiana, the U.S. Army Corps of Engineers (USACE) has implemented design guidelines that both levees and structures shall be designed to. Historically, USACE has used concrete piles or steel H-piles as the foundations for these structures. Because of the magnitude of obtaining 100-year level hurricane protection, limited resources, and a condensed timeline, spiral welded pipe piles can be manufactured as an alternative to either the concrete piles or steel H-piles. This research will provide the necessary background for understanding pile foundations, will compare the behaviors of spiral welded pipe …

The Petrochemical Industrial Complex Of The St. Charles Parish Industrial Corridor And Its Influence On Urbanization Patterns, Darin Acosta Dec 2010

The Petrochemical Industrial Complex Of The St. Charles Parish Industrial Corridor And Its Influence On Urbanization Patterns, Darin Acosta

LSU New Orleans Theses and Dissertations

This thesis explores the impact that the petrochemical industry has had on the built environment of Norco, St. Charles Parish, Louisiana. Previous scholars have suggested that heavy industry in Norco consumes a majority of the Mississippi River's natural levee, which is the most elevated and flood resistant land in the town. In order to test these observations, the author of this thesis has collected parcel-level land use data in Norco to determine the flood hazard and topographical characteristics of these various land uses. Spatial calculations, run using Geographic Information System software, have determined that heavy industrial land uses in Norco …

An Examination Of Faculty Satisfaction At Two-Year Higher Education Institutions, Nancy Kinchen Dec 2010

An Examination Of Faculty Satisfaction At Two-Year Higher Education Institutions, Nancy Kinchen

LSU New Orleans Theses and Dissertations

Part-time faculty members represent the majority of faculty at public two-year postsecondary institutions. Utilizing part-time faculty enables two-year institutions to control their instructional costs and maintain scheduling flexibility. However, part-time faculty are diverse in regards to their employment preference, some prefer part-time employment while others would prefer a full-time position. Since retaining and attracting qualified and experienced part-time faculty members is essential, it is imperative that their satisfaction be understood. This study uses the 2004 National Study of Postsecondary Faculty (NSOPF: 04) to study faculty satisfaction. Faculty was disaggregated according to employment preference into full-time, involuntary part-time, and voluntary part-time …

Street Art: Its Display In Public Space And Issues Within A Municipality, Katherine Gunnell Dec 2010

Street Art: Its Display In Public Space And Issues Within A Municipality, Katherine Gunnell

LSU New Orleans Theses and Dissertations

Hip Hop graffiti has been marking our urban landscapes for decades. However street art, a much less researched topic, has claimed notoriety in recent years. Much of the existing research groups hip-hop graffiti, gang graffiti and street art together and calls for a uniform response from communities, city officials and law enforcement. While street artists have made their mark in the urban landscapes of the United States as well as internationally, it is important to define the terms "street art"and "graffiti" and where they deviate from one another in order for cities to begin to address these expressions with any …

Costs Of Treating Depression With Individual Versus Family Therapy, Sareta Dobbs Head Dec 2010

Costs Of Treating Depression With Individual Versus Family Therapy, Sareta Dobbs Head

Theses and Dissertations

Marital discord contributes to the development and continuation of depression and to the recurrence of depressive episodes for those in troubled relationships. Early research suggests that family therapy may reduce the severity and frequency of depressive episodes through modification of family interactional patterns. This would result in a reduction in the cost of treating depression. This study summarizes the literature linking family dynamics with depression. Then,using a sample taken from a large health maintenance organization, data was statistically analyzed to measure the effectiveness of both individual and family therapy as delivered by different types of mental health professionals. Results indicated …

Ecology Of Prince Of Wales Spruce Grouse, Aleya R. Nelson Dec 2010

Ecology Of Prince Of Wales Spruce Grouse, Aleya R. Nelson

Biological Sciences

Recently, spruce grouse on Prince of Wales Island (POW) in southeast Alaska have been proposed as a separate subspecies. Furthermore, life-history of spruce grouse on POW, which is temperate coastal rainforest, varies sufficiently from birds in mainland areas, mostly boreal forest, to warrant specific management. Therefore, I examined the ecology of spruce grouse on POW to determine how timber harvest influences their survival and habitat selection and ultimately to provide recommendations for their conservation. During 2007-2009, we found that the greatest variation in survival probability was attributed to breeding status. The annual survival of non-breeding birds was 0.72±0.082 (S±) while …

Waterbird Distribution And Habitat In The Prairie Pothole Region, U.S.A., Valerie Steen Dec 2010

Waterbird Distribution And Habitat In The Prairie Pothole Region, U.S.A., Valerie Steen

Biological Sciences

The Prairie Pothole Region (PPR) of north-central North America provides some of the most critical wetland habitat continent-wide to waterbirds. Agricultural conversion has resulted in widespread wetland drainage. Furthermore, climate change projections indicate a drier future, which will alter remaining wetland habitats. I evaluated Black Tern (Chlidonias niger) habitat selection and the potential impacts of climate change on the distribution of waterbird species. To examine Black Tern habitat selection, I surveyed 589 wetlands in North and South Dakota in 2008-09, then created multivariate habitat models. I documented breeding at 5% and foraging at 17% of wetlands surveyed, and found local …
