Robert Habersham (1783-1870)

Robert Habersham (1783-1870) was a Georgia planter and merchant who lived from the time of the Revolution until the days of Reconstruction. He was part of the Habersham clan which had so much to do with the founding and growth of Georgia. Robert\u27s grandfather, James, came to Georgia with George Whitfield. Robert\u27s father, Joseph, was active in the Revolution and the early Republic, serving in the Provisional Congress and as this country\u27s first Postmaster General. Robert Habersham added to the family honor during his own life in Savannah. He was a merchant for some sixty years, owned several well-known Savannah plantations (Causton\u27s Bluff, Deptford, etc.), and was a faithful, long-time vestryman for Christ Episcopal Church. Treasurer for Chatham County.He was also Robert Habersham was extremely successful in his business, leaving an estate valued at over $164,000 (despite his loses during and following the Civil War). He was also a family man, Marrying three times. He married Mary O\u27Brien of Beaufort, South Carolina; Elizabeth Neyle; and his first cousin, Mary Butler Habersham. He had several children. Robert lived a full life and died of old age. He is buried in the Habersham family section of Laurel Grove Cemetery.https://digitalcommons.georgiasouthern.edu/sav-bios-lane/1094/thumbnail.jp

Applying Emotional Analysis for Automated Content Moderation

The purpose of this project is to explore the effectiveness of emotional analysis as a means to automatically moderate content or flag content for manual moderation in order to reduce the workload of human moderators in moderating toxic content online. In this context, toxic content is defined as content that features excessive negativity, rudeness, or malice. This often features offensive language or slurs. The work involved in this project included creating a simple website that imitates a social media or forum with a feed of user submitted text posts, implementing an emotional analysis algorithm from a word emotions dataset, designing a system to configure tolerance thresholds on a per-emotion basis, implementing the process of determining violations of incoming text posts using the configuration, and testing the effectiveness of the emotional analysis algorithm at determining toxic posts using a dataset of posts that have been manually reviewed for toxicity by a group of human moderators

AIDS AND THE COLLEGE STUDENT: KNOWLEDGE, BELIEFS, AND INFORMATION SEEKING

A questionnaire on knowledge, beliefs, and information-seeking behavior about Acquired Immune Deficiency Syndrome (AIDS) was administered to a total of 1,300 university students, and 1,001 were completed and returned. The aim of the study was to investigate the relationship between college students' knowledge and beliefs about AIDS and their information-seeking behavior about AIDS. Students were found to be knowledgeable about the disease, but the majority (50.5%) were not worried about contracting AIDS. The findings revealed that students who are more knowledgeable about AIDS seek more information than those less knowledgeable about AIDS. It was also found that students who feel more highly susceptible to AIDS are more likely to seek information about the disease. The primary sources of student information on AIDS were television, newspapers, magazines, and radio; however, doctors and health-care professionals were considered the most trust-worthy sources of AIDS information. The data suggest that medically supported information on AIDS should be provided to college students by health educators via the popular media sources

Collision Avoidance for UAVs Using Optic Flow Measurement with Line of Sight Rate Equalization and Looming

A series of simplified scenarios is investigated whereby an optical flow balancing guidance law is used to avoid obstacles by steering an air vehicle between fixed objects/obstacles. These obstacles are registered as specific points that can be representative of features in a scene. The obstacles appear in the field of view of a single forward looking camera. First a 2-D analysis is presented where the rate of the line of sight from the vehicle to each of the obstacles to be avoided is measured. The analysis proceeds by initially using no field of view (FOV) limitations, then applying FOV restrictions, and adding features or obstacles in the scene. These analyses show that using a guidance law that equalizes the line of sight rates with no FOV limitations, actually results in the vehicle being steered into one of the objects for all initial conditions. The research next develops an obstacle avoidance strategy based on equilibrating the optic flow generated by the obstacles and presents an analysis that leads to a different conclusion in which balancing the optic flows does avoid the obstacles. The paper then describes a set of guidance methods that with real FOV limitations create a favorable result. Finally, the looming of an object in the camera\u27s FOV can be measured and used for synthesizing a collision avoidance guidance law. For the simple 2-D case, looming is quantified as an increase in LOS between two features on a wall in front of the air vehicle. The 2-D guidance law for equalizing the optic flow and looming detection is then extended into the 3-D case. Then a set of 3-D scenarios are further explored using a decoupled two channel approach. In addition, a comparison of two image segmentation techniques that are used to find optic flow vectors is presented

Investigation of fanless PCs: design and optimization

The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Title from PDF of title page (University of Missouri--Columbia, viewed on January 14, 2010).Thesis advisor: Dr. James Bryan.Includes bibliographical references.M.S. University of Missouri--Columbia 2009.Dissertations, Academic -- University of Missouri--Columbia -- Mechanical and aerospace engineering.The purpose of this research is to fundamentally explore the limitations of natural convection as it pertains to the cooling of desktop personal computers (PCs) and, in particular, maximize total thermal loads while minimizing the volume of the complete package. This research is directed towards the ultimate goal of finding the optimum design of a sealed, Fanless personal computer conforming to the Ultra Small Form Factor (USFF). The work presented herein has developed the foundational tools and knowledge base required to accomplish the stated goal from a thermal perspective. This was realized in three unique investigations: heat sink optimization, thermal spreading analysis, and heat pipe implementation study. A program was developed utilizing a cumulative empirical correlation database to output optimized heat sink designs. A look at lumped capacitance, as well as numerical, analytical, and experimental comparisons for spreading resistance revealed good results for simple analytical approximations as a design tool. Finally, heat pipe implementation was looked at from several common design assumption angles allowing for several valuable conclusions to be made on heat pipe placement in any future Fanless PC design

Cobalt-Porphyrin Catalyzed Electrochemical Reduction of Carbon Dioxide in Water II: Mechanism from First Principles

We apply first principles computational techniques to analyze the two-electron, multi-step, electrochemical reduction of CO2 to CO in water using cobalt porphyrin as a catalyst. Density Functional Theory calculations with hybrid functionals and dielectric continuum solvation are used to determine the steps at which electrons are added. This information is corroborated with ab initio molecular dynamics simulations in an explicit aqueous environment which reveal the critical role of water in stabilizing a key intermediate formed by CO2 bound to cobalt. Using potential of mean force calculations, the intermediate is found to spontaneously accept a proton to form a carboxylate acid group at pH<9.0, and the subsequent cleavage of a C-OH bond to form CO is exothermic and associated with a small free energy barrier. These predictions suggest that the proposed reaction mechanism is viable if electron transfer to the catalyst is sufficiently fast. The variation in cobalt ion charge and spin states during bond breaking, DFT+U treatment of cobalt 3d orbitals, and the need for computing electrochemical potentials are emphasized.Comment: 33 pages, 7 figure

Beagle, Oregon, An Unknown Casualty of War: Camp White and the Destruction of a Farming Community During the Second World War

This project examines the landscape of the farming community of Beagle, Oregon prior to and during the Second World War and the effect on it due to the construction of Camp White, a World War II training facility. The Beagle landscape is examined through the prism of current theory that suggests that landscapes are not discrete units of analysis but are, instead, symbiotic relationships between land and people. Utilizing archives, contemporary newspaper accounts, photographs, oral histories, and archaeological investigation, the history of the construction of Beagle landscape, the effects of the construction of Camp White, the subsequent removal of Beagle residents, and postwar renewal are examined. The project concludes that the Beagle landscape was, and is, a holistic entity that, though dramatically changed in 1942, continues to exist and inform the lives of surviving original residents as well as the history of the Beagle area
