Fault Location Algorithms, Observability And Optimality For Power Distribution Systems, Wanjing Xiu

Theses and Dissertations--Electrical and Computer Engineering

Power outages usually lead to customer complaints and revenue losses. Consequently, fast and accurate fault location on electric lines is needed so that repair work can be carried out as fast as possible.

Chapter 2 describes novel fault location algorithms for radial and non-radial ungrounded power distribution systems. For both types of systems, fault location approaches using line to neutral or line to line measurements are presented. It’s assumed that network structure and parameters are known, so that during-fault bus impedance matrix of the system can be derived. Functions of bus impedance matrix and available measurements at substation are formulated, …

Prediction Model To Estimate The Zero Crossing Point For Faulted Waveforms, Md. Shakawat Hossan

Theses and Dissertations--Electrical and Computer Engineering

In any power system, fault means abnormal flow of current. Insulation breakdown is the cause of fault generation. Different factors can cause the breakdown: Wires drifting together in the wind, Lightning ionizing air, wires with contacts of animals and plants, Salt spray or pollution on insulators. The common type of faults on a three phase system are single line-to-ground (SLG), Line-to-line faults (LL), double line-to-ground (DLG) faults, and balanced three phase faults. And these faults can be symmetrical (balanced) or Unsymmetrical (imbalanced).In this Study, a technique to predict the zero crossing point has been discussed and simulated. Zero crossing point …

Robomirror: A Simulated Mirror Display With A Robotic Camera, Yuqi Zhang

Theses and Dissertations--Electrical and Computer Engineering

Simulated mirror displays have a promising prospect in applications, due to its capability for virtual visualization. In most existing mirror displays, cameras are placed on top of the displays and unable to capture the person in front of the display at the highest possible resolution. The lack of a direct frontal capture of the subject's face and the geometric error introduced by image warping techniques make realistic mirror image rendering a challenging problem. The objective of this thesis is to explore the use of a robotic camera in tracking the face of the subject in front of the display to …

Meglumine Exerts Protective Effects Against Features Of Metabolic Syndrome And Type Ii Diabetes, Arturo Bravo Nuevo, Alice Marcy, Minzhou Huang, Frank Kappler, Jennifer Mulgrew, Lisa Laury-Kleintop, Melvin Reichman, Annette Tobia, George C Prendergast

PCOM Scholarly Works

Metabolic syndrome, diabetes and diabetes complications pose a growing medical challenge worldwide, accentuating the need of safe and effective strategies for their clinical management. Here we present preclinical evidence that the sorbitol derivative meglumine (N-methyl-D-glucamine) can safely protect against several features of metabolic syndrome and diabetes, as well as elicit enhancement in muscle stamina. Meglumine is a compound routinely used as an approved excipient to improve drug absorption that has not been ascribed any direct biological effects in vivo. Normal mice (SV129) administered 18 mM meglumine orally for six weeks did not display any gastrointestinal or other observable adverse effects, …

Within-Season Nest Reuse By Mountain Plovers (Charadrius Montanus) In Eastern Colorado, Lani T. Stinson, Victoria J. Dreitz

Wildlife Biology Faculty Publications

The Mountain Plover (Charadrius montanus) is a declining migratory shorebird that nests on shortgrass prairies across the western Great Plains. This ground-nesting species exhibits an uncommon split-clutch mating system, in which each member of a pair simultaneously incubates a nest and uniparental care continues throughout brood-rearing. We report on an observation of within-season nest reuse in this species. To our knowledge, this report includes the first documented occurrence of 2 different Mountain Plovers using the same nest cup in the same breeding season. Nest reuse could represent a time- and energy-saving strategy for renesting individuals.

Rethinking The Theory Of The Class Action: The Risks And Rewards Of Capitalistic Socialism In The Litigation Process, Martin H. Redish

Emory Law Journal

Despite all of the controversial scholarship that has been published in recent years concerning the modern class action, it is both puzzling and disappointing how little of it has sought to grasp the deep structural precepts underlying the device. All too often, the scholarly debate, not to mention the political debate, has broken down along ideological lines: the political left has reflexively favored the device and the political right has reflexively opposed it. Virtually all of even the serious scholarly work done on the subject has, for the most part, been superficial, failing to pursue, much less to grasp, the …

Research And Documentation In The 21st Century: Oral History And Genealogy Of The Yuan Shikai Family, Sheau-Yueh J. Chao

Publications and Research

The oral histories and genealogies have long been used by historians, archaeologists, sociologists, ethnologists, and demographers in their investigation of past human behavior on social and historical evidences relating to a lineage organization or a clan. Chinese genealogical records has been used for thousands of years to record the genealogical history of a family, including a family’s origin, its subordinate lines, names and ages of the members, records of marriages, births and deaths, merits and deeds, and in early days brief biographical information of solely the male family members. This paper will examine the history of Chinese names and the …

On The Matter Of God’S Goodness: An Examination Of The Failure Of Theodicies, Herman Melville, And An Alternative Approach To The Problem Of Evil, Marie Angeles

Scripps Senior Theses

Within Judeo-Christianity there is a belief in an all perfect God who is omniscient, omnipotent, and omnibenevolent. However, in this world evil and suffering exists, so how is it possible that an all perfect God can exist? This is called the problem of evil. This thesis examines the problem of evil and how philosophers like Alvin Plantinga, John Hick, and Richard Swinburne attempt to solve the problem of evil through different theodicies. In this paper I argue that all three philosophers and their theodicies fail to solve the problem of evil. I then turn to the writings of Herman Melville, …

Internet Content Governance And Human Rights, Nicola Lucchi

Vanderbilt Journal of Entertainment & Technology Law

The Internet has become an essential tool for various life-related purposes, and it is an instrument necessary for the proper enjoyment of a series of rights-including the right to access knowledge and information and the right to communicate. This new paradigm also implies that all people should have access to the Internet at affordable conditions, and any restrictions should be strictly limited and proportionate. As a consequence, any regulatory and policy measures that affect the Internet and the content that flows over it should be consistent with basic rights and liberties of human beings. This Article intends to explore the …

Firesetting Behavior And Psychiatric Disorders, Stephanie Stockburger, Hatim A. Omar

Pediatrics Faculty Publications

Firesetting behavior results in serious damage to lives and property every year. Firesetting has been linked to a number of comorbid psychiatric disorders including depression, substance abuse, conduct disorder, antisocial personality disorder, obsessive compulsive disorder, psychotic disorder, schizoid personality disorder, and schizophrenia. Psychiatric disorders differ by gender. In addition, juvenile firesetters have history of a separate set of psychiatric comorbidities. The strong correlation between psychiatric comorbidities and firesetting behavior illustrates the need for fire service and mental health collaboration.

Self-Reported Juvenile Firesetting, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

In this chapter we address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Logistic regressions were run to determine if attention problems predicted firesetting and the findings indicated that attention problems are predictive of self-reported firesetting. The …

The Merchants Of Moocs, James Grimmelmann

Cornell Law Faculty Publications

A loose network of educators, entrepreneurs, and investors are promoting Massive Open Online Courses as an innovation that will radicaly disrupt higher education. These Merchants of MOOCs see MOOCs' novel features -- star professors, flipped classrooms, economies of scale, unbundling, and openness -- as the key to dramatically improving higher education while reducing its cost.

But MOOCs are far from unprecedented. There is very little in them that has not been tried before, from 19th-century correspondence courses to Fathom, Columbia's $25 million dot-com boondoggle. Claims of disruption look rather different when this missing context is restored. This essay examines some …

Rethinking Sovereign Debt: Politics, Reputation, And Legitimacy In Modern Finance, Odette Lienau

Cornell Law Faculty Publications

Conventional wisdom holds that all nations must repay debt. Regardless of the legitimacy of the regime that signs the contract, a country that fails to honor its loan obligations damages its reputation, inviting still greater problems down the road. Yet difficult dilemmas arise from this assumption. Should today's South Africa be responsible for apartheid-era debt? Is it reasonable to tether postwar Iraq with Saddam Hussein's excesses? Rethinking Sovereign Debt is a probing historical analysis of how sovereign debt continuity - the rule that nations should repay loans even after a major regime change or expect reputational consequences - became the …

Nursing Pain Assessment & Management: A 3d Interactive Simulation, Enilda Romero-Hall, Ginger S. Watson, Yiannis Papelis, Hector Garcia

STEMPS Faculty Publications

In this design case, a team developed a 3D interactive simulation for nursing students and professional nurses to train and practice pain assessment and management procedures. In the simulation environment, the trainees interact with three emotionally expressive animated patients. The three patients vary in their ethnicity, age, and emotion intensity. Successful completion of the scenario requires that the trainee perform of a series of pain assessment and management tasks. The trainee is evaluated on the efficiency and appropriate sequencing of the tasks.

The purpose of this paper is to describe the decisions made regarding the type of virtual patients used, …

Preliberal Autonomy And Postliberal Finance, Robert C. Hockett

Cornell Law Faculty Publications

Even American Founders whose views diverged as dramatically as those of Jefferson and Hamilton shared a view of finance and of enterprise that one might call “productive republican.” Pursuant to this vision, financial and other forms of market activity are instrumentally rather than intrinsically good — and for that very reason are of interest to the public qua public rather than to the public qua aggregate of “private” individuals. Citizens are best left free to engage in financial and other market activities, per this understanding, only insofar as these are consistent with sustainable collective republic-making. And the republic — the …

Impact Of Gums On The Growth, Viability, And Enzyme Activity Of Lactobacillus Species, Bernice D. Karlton-Senaye

Dissertations

This study investigated the impact of ten selected gums (carrageenan, carrageenan-maltodextrin, guar, locust bean, pectin, pectin- dextrose, pectin-carrageenan, guar-locust bean-carrageenan, inulin, and xanthan) on the growth of eight Lactobacillus strains in laboratory media. The bacterial population for eight Lactobacillus strains was determined in modified basal media at different concentration (0%, 0.25% and 0.5% w/v) of gums stored up to 12 hours at 37 °C. Findings show significant differences (p < 0.05) between the treated and control sample. Guar was found to be the best gum to enhance growth of L. rhamnosus GG B101, L. rhamnosus GG B101, L. delbrueckii subsp. bulgaricus SD35, L. delbrueckii subsp. bulgaricus SD33, L. acidophilus SD 16, L. acidophilus EF7, L. reuteri DSM20016, L. reuteri CF2-2F during 12 hours of storage at 37 C in laboratory media. The population of L. rhamnosus GGB101 in the samples containing gums were significantly (p < 0.05) higher than the control without gums. Samples containing 0.5% gums showed slightly higher bacterial population than those with 0.25% of gum. A minimum of 12 hour of incubation period was shown to be adequate to reach a bacterial population of 6 log CFU/mL in the presence of gums. Addition of guar (0.5%) led to the highest (1.31 log CFU/mL) increase in population of the treated L. rhamnosus GGB101 over the control. There was no marked (p < 0.05) change in pH and titratable acidity. Four different gums (carrageenan, carrageenan-maltodextrin, pectin-carrageenan, guar-locust bean-carrageenan) were selected to determine the effect on the growth, viability and betagalactosidase activity of four selected Lactobacillus strains (L. rhamnosus GG B101, L. rhamnosus GG B101, L. reuteri DSM20016, L. reuteri CF2-2F). Effect of the four selected gums on thegrowth L. rhamnosus GG B101, L. rhamnosus GG B101, L. reuteri DSM20016 in milk were compared to those in modified basal media. Results showed that xanthan induced highest growth of L. rhamnosus GG B103, L. rhamnosus GG B101 in milk whereas carrageenanmaltodextrin led to highest growth of L. reuteri DSM 20016 in the media. Marked differences (p < 0.05) in viability were observed between milk samples containing gums and the control. The presence of carrageenan-maltodextrin led to the highest viable counts (8.76 ± 0.03 log CFU/mL) of L. rhamnosus GGB103 during storage. The average population of L. rhamnosus GGB101 and Lactobacillus rhamnosus GGB103 was 8 log CFU/mL, whereas that of Lactobacillus reuteri DSM20016 and Lactobacillus reuteri SD2112 decreased slightly ( 0.15-0.64 log CFU/mL) to 7 log CFU/mL during the storage period. Viable counts were retained at 7-8 log CFU with no significant difference in the control versus treated strains except in the presence of carrageenanmaltodex. Guar-locust bean-carrageenan led to significant (p < 0.05) highest levels of β-gal activity of L. rhamnosus GGB103 (1287 ± 4.24 Miller units/ mL) compared to the control (78 ± 2.83 Miller units/ mL). L. rhamnosus GG B101and L. rhamnosus GG B103 were the best strains to attain enhanced levels of β-galactosidase activity. This shows that the inclusion of carrageenan-maltodextrin and guar-locust bean-carrageenan in milk could improve growth, viability and achieve an enhanced level of β-galactosidase activity in L. rhamnosus GG B101 and L. rhamnosus GG B103. The information gleaned from this study could be used in the food industry to improve the quality of probiotic functional foods and thereby contribute to the alleviation of lactose malabsorption.

Perception Analytics Of An In-Depth Observational Analysis Of 6th Grade African American Male Students' Personal Agency, Devetta Holman Nash

Dissertations

Existing scholarship on self-concept and its relevance to personal agency in the classroom does not incorporate the lived experiences of African American middle school boys. Today, in the United States, only 10% of 8th grade African American boys can read proficiently (Holzman, 2011). This research study investigates the perceptions of seventeen middle school African American males' classroom experiences to determine factors that contribute to their classroom engagement and personal agency. The study also illustrates that there is a significant need for greater self-identity and self-concept within the learning environment, which allows African American male students to self–actualize their sense of …

The Rate And Process Of Mangrove Forest Expansion On Above- And Belowground Carbon Relations In Coastal Louisiana, Hai Thanh Pham

Dissertations

Global climate change is a major environmental threat to natural and cultural resources in low-lying coastal zones and deltas worldwide. It is expected to have a significant effect on the development of coastal wetlands by changing species range expansion. In fact, recent studies have shown that there has been an increasing mangrove encroachment poleward in the Southern and Northern Hemispheres into temperate saltmarsh zones due to the lack of freeze events. This phenomenon could have a critical impact on the structure and function of tidal wetlands at critical latitudes, especially in carbon sequestration, since mangroves are thought to sequester more …

Teacher Perceptions On Teacher Leadership And Shared Vision In Nc Schools: A Correlational Study Using The Nc Teacher Working Conditions Survey, Mary M. Hemphill

Dissertations

As the landscape of public education continues to evolve, so does the leadership and vision required to meet the needs of this ever-changing academic platform. No longer is academic research focusing solely on school leadership required to lead 21st century students and educators toward success, but rather it is focused on the plethora of factors that inform the development of thriving learning communities across our nation. While much of the educational discourse on leadership and vision speaks to the development of strategies, pedagogies, and leadership preparation for school leaders, there are deficiencies in the literature on teacher leadership and shared …
