Indoor Localization And Tracking Using Binary Information, Li Geng

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Real-time localization and tracking of people and assets within buildings is in high demand in many applications. These tasks are very challenging in indoor environments due to the physics of signal propagation and the multi-path interference. Satellite-based technologies such as the Global Positioning Systems (GPS) are notoriously unreliable in indoor environments. As a result, a variety of novel technologies have been developed to fill this gap. This dissertation focuses on the use of binary information for indoor localization and tracking, and in particular, on the use of the Ultra High Frequency (UHF) Radio Frequency Identification (RFID) technology. RFID is a …

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Microsystems that harvest ambient power for their operation have been present in RFID technology and implantable medical devices (IMDs) for couple of decades. With the recent applications under the framework of the Internet of Thing (IoT) and with miniaturization of implantable devices interest in these devices has significantly grown. Two of the critical subjects in the passive devices technology are wireless power transfer (WPT) and data link. The focus of this work is on two distinct applications: design of wireless power transfer for IMDs and backscatter-based tag-to-tag (BBTT) communication system. Our goal in the design of WPT to IMDs is …

Super-Hydrophobic High Throughput Electrospun Cellulose Acetate (Ca) Nanofibrous Mats As Oil Selective Sorbents, Chao Han

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The threat of oil pollution increases with the expansion of oil exploration and production activities, as well as the industrial growth around the world. Use of sorbents is a common method to deal with the oil spills. In this work, an advanced sorbent technology is described. A series of non-woven Cellulose Acetate (CA) nanofibrous mats with a 3D fibrous structure were synthesized by a novel high-throughput electrospinning technique. The precursor was solutions of CA/ acetic acid-acetone in various concentrations. Among them, 15.0% CA exhibits a superhydrophobic surface property, with a water contact angle of 128.95°. Its oil sorption capacity is …

Multi-Marker Linkage Disequilibrium Mapping Of Quantitative Trait Loci, Soyoun Lee

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Background: Genome-wide associations have been studied for years to infer relationships between biological traits and their underlying genetic causes, known as quantitative traits loci (QTL), in a process known as QTL mapping. Single nucleotide polymorphisms (SNPs), which are commonly used genetic markers, are usually in linkage disequilibrium (LD) with each other within a small genetic region. Both single- and double-marker-based LD mapping methods have been developed by taking advantage of LD structure. Method: In this thesis, a more general LD mapping framework with an arbitrary number of markers has been developed in order to improve LD mapping and its detection …

Groundwater Nitrate Contamination Remediation Through Permeable Reactive Barriers On The Forge River, Long Island, New York, Amy Bronwan Pritt

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Forge River on the south shore of Long Island is contaminated by nitrate. The Forge River leads into Moriches Bay. Nitrate contamination in the river leads to algal blooms, hypoxia of the river and eventually fish kills. The area surrounding the Forge River is largely residential and not sewered with the residents relying on septic systems for sewage disposal. Nitrate from even small septic systems has been found in groundwater as far as 100m down gradient. Other investigators have shown the occurrence of submarine groundwater discharge on Wills Creek, a tributary of the Forge River and my study site. …

Marine Acoustics And Habitat Mapping In The Peconic Estuary, Ny, Michael Patrick White

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

As coastal populations grow, there is an increasing need for better spatial management of the seafloor. Multibeam backscatter data can be a powerful tool for habitat mapping and segmenting large areas of the seabed, based on similar physical characteristics. In order to increase the effectiveness of backscatter data sets, MBES data from the Peconic Estuary, NY, is reprocessed using newly developed software. These mosaics are less noisy compared to prior results. The relationship between grain size and backscatter is found to have a good correlation in the Peconic Estuary and a simple regression is used to predict mean phi size …

Space Acquisition Strategies Of Zostera Marina, Bradley Thomas Furman

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Seagrasses are a diverse group of clonal marine macrophytes. Their decline in recent decades has been an alarming component of estuarine urbanization, with large portions of historical coverage lost or degraded. Understanding patterns of dispersal and recruitment within and among the remaining populations is now critical to predicting the form and pace of recovery. Working in a developing eelgrass (Zostera marina) meadow in Shinnecock Bay, we combined field manipulations, genotypic surveys and correlative analyses to understand how vegetative growth and seedling recruitment contribute to space acquisition. First, we explored clonal foraging behavior and its effect on patch growth using subterranean …

Denitrifying Bioreactors: A Solution To Groundwater Nitrate Pollution At The Forge River?, Christine Jean Gurdon

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Denitrifying bioreactors are an approach to remediate groundwater contaminated with nitrate. Their popularity as a remediation system has increased due to their unnecessary maintenance, low cost, and longevity. While field trials on their performance have been conducted, few have been completed in a marine coastal environment. In this study, a denitrification wall was designed to be installed and monitored along the shore of a coastal environment, namely, the Forge River, New York. Prior to the design phase, a groundwater plume of elevated nitrate-nitrite concentrations needed to be identified. Groundwater nitrate-nitrite concentrations ranged from 0.01-17.68 mg/L along Riviera Drive, a road …

Fight Or Flight: Mobility, Political Behavior, And Nativism In The United States, Yamil Velez

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In recent decades, communities across the United States have seen increases in hostility toward immigrants. Prevailing theories in political science hold that responses to immigration are, in part, a function of local area demographics. However, assessments of these theories suffer from the critique that local area demographics and immigration preferences may be endogenous due to residential self-selection. Recent efforts sidestep this problem by using clever modeling strategies or experiments. Rather than viewing self-selection as a nuisance, however, this article develops and tests a theory that treats migration and political behavior as strategies residents invoke in the presence of local immigration. …

American Literary Regionalism And The Sister Arts: Local Color Outside The Lines, Brandi Dawn So

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Abstract of the Dissertation American Literary Regionalism and the Sister Arts: Local Color Outside the Lines by Brandi So Doctor of Philosophy in English Stony Brook University 2015 American literary regionalism was partitioned off from literary realism in a manner that marginalized a movement dominated by women. The gendering of the genre stems in part from the unprecedented integration of women authors into the mainstream market. Conversely, the masculinization of literary ekphrasis still actively shapes its relative discourse. Traditional characterizations of ekphrasis imagine a masculine and aggressive act upon a disempowered, voiceless, feminized object. The timbre of this conversation is …

Implications Of Early-Onset Psychiatric Symptoms For Peer Functioning In Middle-Childhood: A Validity And Clinical Significance Approach, Allison Pennock Danzig

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Recent findings indicate that preschoolers experience psychiatric symptoms at rates similar to that of older children and adolescents. However, there are limited data examining the impact of early-onset psychiatric symptoms on subsequent peer functioning. To support the validity and clinical significance of early-emerging symptoms, it is necessary to demonstrate that youth with elevated symptom levels experience significant later difficulties across various domains. Most research linking these constructs has examined the impact of externalizing symptoms on peer functioning cross-sectionally, without consideration of internalizing symptoms. The goals of this study were to derive multiple-informant middle-childhood peer factors, examine the longitudinal impact of …

The Effect Of Cognitive Load On Lexical Activation And Competition, Xujin Zhang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Current models of spoken word recognition suggest that multiple lexical candidates are activated in parallel upon hearing an utterance, with these lexical hypotheses competing with each other for recognition. This dissertation includes a set of priming experiments that investigate the effect of cognitive load on multiple lexical activation and competition. The lexicality of the primes (i.e. | Non-Word vs. Word) and the demands of two primary tasks (i.e. | Rhyme vs. Association) were manipulated. In six experiments, I tested performance on the two primary tasks under conditions with no additional cognitive load, or with secondary tasks that either imposed phonological …

Long-Term Seizure And Psychosocial Outcomes Of Vagus Nerve Stimulation For Intractable Epilepsy, Vibhangini S. Wasade, Lonni Schultz, Karthik Mohanarangan, Aryamaan Gaddam, Jason M. Schwalb, Marianna Spanaki-Varelas

Neurology Articles

Vagus nerve stimulation (VNS) is a widely used adjunctive treatment option for intractable epilepsy. Most studies have demonstrated short-term seizure outcomes, usually for up to 5 years, and thus far, none have reported psychosocial outcomes in adults. We aimed to assess long-term seizure and psychosocial outcomes in patients with intractable epilepsy on VNS therapy for more than 15 years. We identified patients who had VNS implantation for treatment of intractable epilepsy from 1997 to 2013 at our Comprehensive Epilepsy Program and gathered demographics including age at epilepsy onset and VNS implantation, epilepsy type, number of antiepilepsy drugs (AEDs) and seizure …

Biopower: Foucault And Beyond, Vernon W. Cisney, Nicolae Morar

Gettysburg College Faculty Books

Michel Foucault’s notion of “biopower” has been a highly fertile concept in recent theory, influencing thinkers worldwide across a variety of disciplines and concerns. In The History of Sexuality: An Introduction, Foucault famously employed the term to describe “a power bent on generating forces, making them grow, and ordering them, rather than one dedicated to impeding them, making them submit, or destroying them.” With this volume, Vernon W. Cisney and Nicolae Morar bring together leading contemporary scholars to explore the many theoretical possibilities that the concept of biopower has enabled while at the same time pinpointing their most important …

Hemodynamic Analysis Of Fast And Slow Aneurysm Occlusions By Flow Diversion In Rabbits, Bong Jae Chung, Fernando Mut, Ramanathan Kadirvel, Ravi Lingineni, David F. Kallmes, Juan R. Cebral

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

Purpose: To assess hemodynamic differences between aneurysms that occlude rapidly and those occluding in delayed fashion after flow diversion in rabbits. Methods: Thirty-six elastase-induced aneurysms in rabbits were treated with flow diverting devices. Aneurysm occlusion was assessed angiographically immediately before they were sacrificed at 1 (n=6), 2 (n=4), 4 (n=8) or 8 weeks (n=18) after treatment. The aneurysms were classified into a fast occlusion group if they were completely or near completely occluded at 4 weeks or earlier and a slow occlusion group if they remained incompletely occluded at 8 weeks. The immediate post-treatment flow conditions in aneurysms of each …

Leadership Density: An Exploratory Correlational Study Of K-8 Teachers' Balanced Scorecards And Perceptions Of Leadership, Jason David Edwards

Doctor of Education (EdD)

The purpose of this study was to explore possible correlations between how individual teachers experience leadership density and their balanced scorecard totals. The literature review conceptualizes leadership density at the intersection of leadership theory and healthy school culture. Leadership density is then operationalized to a vetted theoretical framework and corresponding instrument. Existing data was derived from a public lottery-based K-8 charter school. As a balanced feedback mechanism for teachers, the site school employed an annual bonus scorecard calculator. Each teacher’s balanced scorecard included academic growth, supervisor evaluation, and parent surveys.

This research aimed to expand scholarly understandings of how teachers …

Perceptions Of Crime Prevention Through Environmental Design (Cpted) At Australian Railway Stations, Paul Cozens, Tiffany Van Der Linde

Journal of Public Transportation

Personal safety and security are essential criteria for measuring the quality of public transport, and research has consistently demonstrated that crime and fear of crime affect levels of patronage. Although authorities throughout the world are implementing Crime Prevention Through Environmental Design (CPTED), research and practice commonly focus on the elements of surveillance, territoriality, and controlling access. Few studies have investigated the CPTED concepts of “image management” or “geographical juxtaposition” (the surrounding environment). This research compares and contrasts the perceptions of rail users and security experts in relation to two railway stations in Perth, Western Australia. One station was designed in …

Green Criminological Concerns & Philosophical Beliefs, Alexander Allen Anderson

Criminology & Criminal Justice Theses - Archive

The purpose of this research project was to test the philosophical argument that people who maintained a dualistic mindset or sustained a belief in the existence of the soul would be less concerned with environmental crime. A survey was collected from a sample of 332 individuals at the University of Texas at Arlington in Arlington, Texas. The survey asked individuals to select on a likert scale how concerned they were with environmental harm. Preceding these, individuals were asked to answer either yes, no, or I don’t know on questions concerning their philosophical beliefs, looking for indicators of dualistic thinking and …

Presidential Speech And The Framing Of Poverty: From The War On Poverty To The War On The Poor, Jamaica Kennedy

Sociology & Anthropology Theses - Archive

Presidential narratives are influential components of the national conversation about social issues. In order to gain a better understanding of how the Presidents framed and discussed poverty and the poor State of the Union addresses between the years 1964 and 2014 were analyzed. The focus of this research was to identify the narratives the Presidents crafted about the war on poverty. Narrative analysis was utilized to unpack and these narratives and identify the different narrative forms they took while the Presidents presented and discussed the war on poverty. Initially the war on poverty was presented as a romantic quest to …

Anger And Posttraumatic Stress Disorder Symptom Severity In A Trauma-Exposed Military Population: Differences By Trauma Context And Gender, Miranda Worthen, Sujit Rathod, Gregory Cohen, Laura Sampson, Robert Ursano, Robert Gifford, Carol Fullerton, Sandro Galea, Jennifer Ahern

Faculty Publications

Studies have found a stronger association between anger and posttraumatic stress disorder (PTSD) severity in military populations than in nonmilitary populations. Two hypotheses have been proposed to explain this difference: Military populations are more prone to anger than nonmilitary populations, and traumas experienced on deployment create more anger than nondeployment traumas. To examine these hypotheses, we evaluated the association between anger and PTSD severity among never-deployed military service members with nondeployment traumas (n = 226) and deployed service members with deployment traumas (n = 594) using linear regression. We further examined these associations stratified by gender. Bivariate associations between anger …

Criminal Law, Bernadette C. Crucilla

Mercer Law Review

The dynamic nature of criminal law is a result of the ongoing struggle between those who prosecute individuals charged with crimes and those who defend them. It is, therefore, not practical to try to include every change in criminal law occurring during a particular survey period. I have sifted through the cases and statutory amendments from June 1, 2014 through May 31, 2015 and selected those with the widest application or interest to criminal law practitioners.

Real Property, Linda S. Finley

Mercer Law Review

A review of the survey of real property law for the last several years shows an evolution of topics. One year the creation of the Georgia Fair Lending Act, and the duties that new legislation placed upon attorneys and lenders was a critical topic; the following year (and the next), the topic of interest was how title to church property is determined when a congregation splits. For the last few years, the downturn in the Georgia and national economy, and the protection of consumers under foreclosure laws and from the unauthorized practice of law, have seen both judicial and legislative …
