The 2004 NASA Faculty Fellowship Program Research Reports

This is the administrative report for the 2004 NASA Faculty Fellowship Program (NFFP) held at the George C. Marshall Space Flight Center (MSFC) for the 40th consecutive year. The NFFP offers science and engineering faculty at U.S. colleges and universities hands-on exposure to NASA s research challenges through summer research residencies and extended research opportunities at participating NASA research Centers. During this program, fellows work closely with NASA colleagues on research challenges important to NASA's strategic enterprises that are of mutual interest to the fellow and the Center. The nominal starting and .nishing dates for the 10-week program were June 1 through August 6, 2004. The program was sponsored by NASA Headquarters, Washington, DC, and operated under contract by The University of Alabama, The University of Alabama in Huntsville, and Alabama A&M University. In addition, promotion and applications are managed by the American Society for Engineering Education (ASEE) and assessment is completed by Universities Space Research Association (USRA). The primary objectives of the NFFP are to: Increase the quality and quantity of research collaborations between NASA and the academic community that contribute to the Agency s space aeronautics and space science mission. Engage faculty from colleges, universities, and community colleges in current NASA research and development. Foster a greater public awareness of NASA science and technology, and therefore facilitate academic and workforce literacy in these areas. Strengthen faculty capabilities to enhance the STEM workforce, advance competition, and infuse mission-related research and technology content into classroom teaching. Increase participation of underrepresented and underserved faculty and institutions in NASA science and technology

Actas do 10º Encontro Português de Computação Gráfica

Actas do 10º Encontro Portugês de Computação Gráfica, Lisboa, 1-3 de Outubro de 2001A investigação, o desenvolvimento e o ensino na área da Computação Gráfica constituem, em Portugal, uma realidade positiva e de largas tradições. O Encontro Português de Computação Gráfica (EPCG), realizado no âmbito das actividades do Grupo Português de Computação Gráfica (GPCG), tem permitido reunir regularmente, desde o 1º EPCG realizado também em Lisboa, mas no já longínquo mês de Julho de 1988, todos os que trabalham nesta área abrangente e com inúmeras aplicações. Pela primeira vez no historial destes Encontros, o 10º EPCG foi organizado em ligação estreita com as comunidades do Processamento de Imagem e da Visão por Computador, através da Associação Portuguesa de Reconhecimento de Padrões (APRP), salientando-se, assim, a acrescida colaboração, e a convergência, entre essas duas áreas e a Computação Gráfica. Este é o livro de actas deste 10º EPCG.INSATUniWebIcep PortugalMicrografAutodes

Landmarks in British history and culture. A monograph of selected issues

The book presents crucial facts and events, selected from the countless defining moments in British history and culture: the appearance of prehistoric man in the British Isles; the influence of Celtic culture from a wider, not only insular perspective; the origins of Anglo-Saxon kingdoms; the historical truth and legendary aspects of the Arthurian myth; sea and imperial expansion; the most important factors and players in the fight for freedom; and finally, the development and cultural meaning of the English concept of sport. Although the author discusses well known historical and cultural events, he does this from a non-British perspective and frequently suggests new hypotheses and analyses for some unsolved problems of British cultural history, such as the lack of English protagonists in Old English literature, the Five Borough question and the etymology of fair play as an ethical term and norm.Książka przedstawia wybrane momenty zwrotne i procesy cywilizacyjne w dziejach i kulturze Wielkiej Brytanii, poczynając od okresu kultur pierwotnych aż do najważniejszych procesów nowożytnych, jak rola protestantyzmu w kształtowaniu się współczesnej cywilizacji brytyjskiej, rozwój idei wolności, ekspansji Imperium Brytyjskiego, morska kultura Anglii oraz odkrycie wszystkich tych zjawisk w literaturze i sztuce

Dynamic surface topography and its application to the evaluation of adolescent idiopathic scoliosis

Dynamic surface topography is a method to quantify the surface and locations of features acquired from moving and distorting shapes against time. This thesis describes the application of the technique to the potential evaluation of adolescent idiopathic scoliosis patients. Scoliosis or curvature of the spine is one of the major skeletal diseases in adolescents where in the majority of cases the cause is unknown or idiopathic. The progression of the disease occurs in three dimensions with the spine simultaneously curving towards the arms and rotating as it collapses with the first indications usually being changes in body symmetry and back surface shape. Following diagnosis, most children do not exhibit any significant worsening of their condition and are routinely monitored using radiography as frequently as every three months whilst vertebral growth potential remains. In a small number of patients, the lateral curvature can unpredictably worsen requiring, in some cases, surgical intervention to prevent further deterioration and to diminish the deformity. Earlier work by many researchers concentrated on attempting to reduce patient exposure to ionizing radiation by investigating if there was a reliable correlation between progression of the scoliosis and changes in surface topography. The techniques have not gained acceptance as the relational algorithms were found to be insufficiently robust in all cases and measurements acquired from available technologies were prone to artefacts introduced by stance, breathing, 'posture and sway. For many patients the motivation in seeking treatment is for the improvement of their appearance rather than to correct the underlying deformity, so cosmetic concerns and an understanding of the psychosocial and physical impacts of the disease and treatments remain important factors in the clinical decision-making process. In the current environment of evidence based medicine there is a growing need to quantify back surface shape, general body asymmetry and patient capability with the objective of producing an agreed scoring to be used in developing treatment plans and assessing outcomes but to date many clinics continue to rely on qualitative methods to describe cosmetic deformity and ability. The aim of the research was to develop an original, low cost and inherently safe apparatus using well understood video based motion capture technology that overcame the disadvantages of earlier work by simultaneously acquiring multiple samples of back surface shape and the locations of bony landmarks to provide averaged results for a quantitative and reliable analysis of cosmetic defect and physical impairment. 172,650 data samples were acquired from thirty skeletally mature subjects not exhibiting any musculoskeletal disease to define normality limits for Page 2 established morphological measurements and to compare the specificity of the approach with existing single sample techniques. Three novel calculations of back paraspinous volumetric asymmetry were tested of which two were found to be potentially useful clinical indicators of deformity and an index was proposed and tested using simulated data that could offer a single value to describe patient back shape asymmetry. Previous research has found that there is a loss of trunk ranges of motion among postoperative patients that has a direct impact on their quality of life, function and physical capability. Data were acquired from the mature subjects and similar results were observed when compared with published data for preoperative scoliosis patients. This thesis has shown that using averaged tri-dimensional morphological and back shape data combined with measurement of dynamic capability acquired using an inherently safe apparatus have the potential to be clinically useful. The opportunity to routinely and safely quantify the cosmetic defect and trunk ranges of motion of adolescent idiopathic scoliosis patients should stimulate more important research to help improve the quality of life of many affected children throughout the world.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
