Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature.

Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature.

Date: December 2008
Creator: Karri, Avinash
Description: Optical current sensors (OCSs) are initially developed to measure relatively large current over a wide range of frequency band. They are also used as protective devices in the event a fault occurs due to a short circuit, in the power generation and distribution industries. The basic principal used in OCS is the Faraday effect. When a light guiding faraday medium is placed in a magnetic field which is produced by the current flowing in the conductor around the magnetic core, the plane of polarization of the linearly polarized light is rotated. The angle of rotation is proportional to the magnetic field strength, proportionality constant and the interaction length. The proportionality constant is the Verdet constant V (λ, T), which is dependent on both temperature and wavelength of the light. Opto electrical methods are used to measure the angle of rotation of the polarization plane. By measuring the angle the current flowing in the current carrying conductor can be calculated. But the accuracy of the OCS is lost of the angle of rotation of the polarization plane is dependent on the Verdet constant, apart from the magnetic field strength. As temperature increases the Verdet constant decreases, so the angle of rotation ...

The employment of historically-informed performance practices in present-day tuba performances of two Italian baroque violoncello transcriptions.

The employment of historically-informed performance practices in present-day tuba performances of two Italian baroque violoncello transcriptions.

Date: May 2008
Creator: Coker, Bradley Gene
Description: As several Italian baroque violoncello transcriptions have entered the standard performance repertory for both high school and collegiate tubists, and as numerous texts, articles, and baroque performance instruction courses have illuminated a new realm of performance possibilities, no published document has provided specific, thorough, and sample approaches to performance on the tuba of a given piece (or pieces) through a detailed application of materials found in any singular source or combination of sources. Many of the existing articles and texts that approach the subject focus largely on ornamentation, while limiting the discussion and application of the following topics: tempo, spirit, affect, notation, rhythm, dynamics, and articulation. This document examines such topics and provides detailed explanations and suggestions of historically-informed characteristics applicable to two movements each from the R. Winston Morris transcription of Antonio Vivaldi's Sonata No. 3 in A Minor and the Donald C. Little/Richard B. Nelson transcription of Benedetto Marcello's Sonata No. V in C Major.

Employment of Older Persons as Foster Grandparents

Employment of Older Persons as Foster Grandparents

Date: August 1966
Creator: Thornton, Russell G.
Description: This thesis is a report of a study of the employment of foster grandparents for the foster grandparent project at the Denton State School in Denton, Texas. There were three specific interests in the study. First, it attempted to ascertain what criteria were used for the hiring of foster grandparents and how they were hired. Included in this area were the necessary steps which an individual had to take to apply for employment. Second, the study was concerned with developing a general description of the social and economic characteristics of those who were hired as foster grandparents, including their performance on certain tests which they took during the employment process. Third, it examined the relationship of selected social and economic characteristics to each other, the inter-relationships of test performance, and the relationships between the selected characteristics and test performance.

Employment of the Rorschach Inkblot Test with the Devries Suicide Inventory

Employment of the Rorschach Inkblot Test with the Devries Suicide Inventory

Date: May 1976
Creator: Gordon, James L.
Description: This investigation represents an attempt to employ the Devries Suicide Prediction Scale and the Rorschach Inkblot Test in a two-stage predictive model which was designed to decrease the high false positive rate associated with the Devries and to design a way in which the Rorschach could be used efficiently in suicide prediction in a large mental hospital setting. The Rorschach was not found to significantly improve the predictive ability of the Devries. An unexpectedly high percentage of mental patients in the study, thirty-eight percent, admitted to previous suicide attempts, raising the question of whether suicidal behavior is not more common than is usually thought.

Empowering the Black Community Faith-Based Economic Development

Empowering the Black Community Faith-Based Economic Development

Date: August 2001
Creator: Gipson, Phillip E.
Description: This paper is addressed to the inner city and some suburban congregations seeking to express their faith through practical initiatives to revitalize their distressed communities. The paper seeks to inspire and instruct the reader with motivational stories containing illustrations of the valuable role that African-American congregations have played in stimulating economic development in their communities. The paper also shows the importance of African-Americans having some control over the flow of economic funds throughout the community. African-American churches in the inner city should undertake significant ventures in community economic development to minister to the temporal as well as the spiritual needs of their communities. This paper will demonstrate how the African-American church, with assistance from federal, state, local programs, and private concerns, can be effective in the urban revitalization.

Empowerment: The Paradigm for Success for the Nursing Homes of the 21st Century

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Connorton, Margaret L.
Description: For a workplace to be successful, it needs to have a higher morale, thus leading to higher quality of care for residents. For a workplace to be successful in empowerment, it must have developed strong teams, and everyone must work as a team and respect one another. The research for this paper focused on many issues. The most important part of my research came from a study of the nursing assistants at Jennings Hall (JH) in Garfield, Ohio. From the data received, I concluded that the two biggest problems in many nursing homes are lack of respect and lack of team-centered attitude.

Emulation & Virtualization as Preservation Strategies

Emulation & Virtualization as Preservation Strategies

Date: 2015
Creator: Rosenthal, David S. H.
Description: Between the two fundamental digital preservation strategies, migration has been strongly favored. Recent developments in emulation frameworks make it possible to deliver emulations to readers via the Web in ways that make them appear as normal components of Web pages. This removes what was the major barrier to deployment of emulation as a preservation strategy. Barriers remain, the two most important are that the tools for creating preserved system images are inadequate, and that the legal basis for delivering emulations is unclear, and where it is clear it is highly restrictive. Both of these raise the cost of building and providing access to a substantial, well curated collection of emulated digital artefacts beyond reach. This book advocates that if the above mentioned barriers can be addressed, emulation will play a much greater role in digital preservation in the coming years. It will provide access to artefacts that migration cannot, and even assist in migration where necessary by allowing the original software to perform it. The evolution of digital artefacts means that current artefacts are more difficult and expensive to collect and preserve than those from the past, and less suitable for migration. This trend is expected to continue. Emulation is ...

Date: December 2014
Creator: Keller, Sarita Talusani
Description: This study is concerned with the roles and relationships between artists-in-residence, community audiences, and program coordinators/art educators as they engage together in community arts programs. This study takes place at Project Row Houses (PRH), a community arts organization located in Houston, Texas and focuses on the artist-in-residence program, which commissions a group of national and international artists for a 6-month period to create art installations in relation to the community and its African-American heritage. This ethnographic case study is based on the activities and events surrounding the 2008 PRH exhibition, Round 29, Thunderbolt Special: The Great Electric Show and Dance, after Sam Lightnin’ Hopkins and employed qualitative data gathering methods of participant-observation, conducting semi-structured, open-ended, in-depth interviews, and through document collection, and contextual information.

Creator: Darweesh, Ali Hussain
Description: The purpose of this study was twofold: (1) to examine the knowledge, skills, and experiences in the enameling arts and the attitudes and perceptions of in-service (n = 12) and pre-service Kuwaiti art teachers (n = 170), art supervisors at the Ministry of Education (MOE) (n = 3) and art education faculty members at the College of Basic Education (CBE) and Kuwait University (KU) (n = 8) about what they believed pre-service art teachers should know and be able to do in order to teach the enameling arts, and (2) to use this information to inform and guide the development of a content outline for an enameling course for pre-service Kuwaiti art teachers that is educationally (how to perform enameling arts skills and how to teach what they know), practically (safety issues, workshop management, etc), and culturally (its relation to Islamic culture) suitable. Both quantitative and qualitative approaches were used. Most of the respondents revealed limited knowledge and skills and modest experiences in the enameling arts. All interviewees in the study expressed positive perceptions and attitudes about the enameling arts. Most agreed that a revision to the current art education curriculum at the CBE was needed and made suggestions about ...

Encoding Variability and Differential Negative Transfer and Retroactive Interference in Children

Encoding Variability and Differential Negative Transfer and Retroactive Interference in Children

Date: August 1975
Creator: Fleming, Frederick G.
Description: Second-graders were tested for negative transfer and retroactive interference using an A-B, A-D paradigm. Four-pair, word-number lists were aurally presented to the children. Subjects were classified as being whole-only encoders or multiple encoders by the use of a recall test presented after list one. Significant negative transfer and retroactive interference were found. The multiple encoders experiences less difficulty in learning the second list that did the whole-only encoders, but these two groups did no differ with regard to transfer or retroactive interference effects. The results were considered in the context of Martin's encoding variability hypothesis.

End of Insertion Detection in Colonoscopy Videos

End of Insertion Detection in Colonoscopy Videos

Date: August 2009
Creator: Malik, Avnish Rajbal
Description: Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to ...

End of Life Care:  African Americans' Disproportionate Use of Hospice

End of Life Care: African Americans' Disproportionate Use of Hospice

Date: December 2010
Creator: McDonald, Ray
Description: The United States of America is a country composed of various ethnicities. This country is considered to be a multi-cultural society. There are various cultural traditions values, norms and superstitious practices within each ethnic group. Attitudes toward end of life care are complex and vary differently across each ethnic group. This study explored factors that explained African Americans' disproportionate use of hospice. Access to hospice care was address, experience with hospice was explored, and recommendations were provided. This study conducted non-experimental research. The design of this exploratory study was quantitative in nature. A survey approach was utilized to collect data that was statistically analyzed. The important concept was African American disproportionate use of hospice. The variable willingness to use was employed to try to explain African Americans' disproportionate use of hospice. The independent variables African Americans who mistrust formal healthcare providers and knowledge about hospice services were operationalized using multiple indicators. The independent variable experience with hospice services did not use a scale. The research findings supported all three study hypotheses. This research results recommend that an important focus of the future be to counsel persons on the availability of hospice as an option for end-of-life care. Well-structured programs of ...
