Aviation safety research and transportation/hazard avoidance and elimination

Data collected by the Scanning Laser Doppler Velocimeter System (SLDVS) was analyzed to determine the feasibility of the SLDVS for monitoring aircraft wake vortices in an airport environment. Data were collected on atmospheric vortices and analyzed. Over 1600 landings were monitored at Kennedy International Airport and by the end of the test period 95 percent of the runs with large aircraft were producing usable results in real time. The transport was determined in real time and post analysis using algorithms which performed centroids on the highest amplitude in the thresholded spectrum. Making use of other parameters of the spectrum, vortex flow fields were studied along with the time histories of peak velocities and amplitudes. The post analysis of the data was accomplished with a CDC-6700 computer using several programs developed for LDV data analysis

Data analysis study and performance evaluation of the scanning laser Doppler system

A simulation program which provided information on theoretically expected vortex spectra, evaluations of potential algorithms, and expected location accuracies for given scan patterns is presented. Field tests using an aircraft engine flow field and aircraft vortices during flyby tests were compared to the results of the simulation. From these studies, a vortex location algorithm was developed which provided vortex location for one or two vortices as a function of time. Results of this algorithm used on data from flyby tests were used to study vortex transport, to evaluate system performance, and to provide suggestions for real-time vortex location algorithms. The results of real-time analysis were compared to those which were expected based on theoretical considerations

Rules for Growth: Promoting Innovation and Growth Through Legal Reform

The United States economy is struggling to recover from its worst economic downturn since the Great Depression. After several huge doses of conventional macroeconomic stimulus - deficit-spending and monetary stimulus - policymakers are understandably eager to find innovative no-cost ways of sustaining growth both in the short and long runs. In response to this challenge, the Kauffman Foundation convened a number of America’s leading legal scholars and social scientists during the summer of 2010 to present and discuss their ideas for changing legal rules and policies to promote innovation and accelerate U.S. economic growth. This meeting led to the publication of Rules for Growth: Promoting Innovation and Growth Through Legal Reform, a comprehensive and groundbreaking volume of essays prescribing a new set of growth-promoting policies for policymakers, legal scholars, economists, and business men and women. Some of the top Rules include: • Reforming U.S. immigration laws so that more high-skilled immigrants can launch businesses in the United States. • Improving university technology licensing practices so university-generated innovation is more quickly and efficiently commercialized. • Moving away from taxes on income that penalize risk-taking, innovation, and employment while shifting toward a more consumption-based tax system that encourages saving that funds investment. In addition, the research tax credit should be redesigned and made permanent. • Overhauling local zoning rules to facilitate the formation of innovative companies. • Urging judges to take a more expansive view of flexible business contracts that are increasingly used by innovative firms. • Urging antitrust enforcers and courts to define markets more in global terms to reflect contemporary realities, resist antitrust enforcement from countries with less sound antitrust regimes, and prohibit industry trade protection and subsidies. • Reforming the intellectual property system to allow for a post-grant opposition process and address the large patent application backlog by allowing applicants to pay for more rapid patent reviews. • Authorizing corporate entities to form digitally and use software as a means for setting out agreements and bylaws governing corporate activities. The collective essays in the book propose a new way of thinking about the legal system that should be of interest to policymakers and academic scholars alike. Moreover, the ideas presented here, if embodied in law, would augment a sustained increase in U.S. economic growth, improving living standards for U.S. residents and for many in the rest of the world

Methods used to evaluate the en dehors or turnout of dancers and classical ballet dancers: a literature review

A técnica do ballet clássico exige a realização máxima do en dehors ou turnout, caracterizado pela rotação externa de membros inferiores. Considerando a sua importância, diversos protocolos para a sua avaliação e mensuração têm sido propostos. O objetivo desta revisão foi investigar sistematicamente quais os métodos utilizados para avaliar o turnout de bailarinos clássicos e/ou praticantes de ballet clássico existentes atualmente. A busca foi feita nas bases de dados Scopus, Science Direct e PubMed, no mês de fevereiro de 2016, e os artigos encontrados deveriam: estar redigidos na língua inglesa, avaliar bailarinos clássicos ou dançarinos que praticassem ballet clássico e mensurar o en dehors ou turnout. Foram encontrados 593 artigos, dos quais 25 foram pré-selecionados para esta revisão, apresentando quinze diferentes métodos e instrumentos de mensuração do turnout: cinemetria; inclinômetro; turnout protactor ou transferidor para medir o turnout; goniômetro; Dupuis Tropometer; transferidor original; fotos dos sujeitos; discos rotacionais; teste de flexibilidade de Nicholas; flexímetro; desenho clínico dos pés; sujeito sobre um pedaço de papel ou solo ou quadro branco; ressonância magnética; filmagem do sujeito executando sequência de passos; Dasco Pro Angle Finder. Esta revisão apresenta forte evidência para afirmar que não há, até o presente momento, um método ou instrumento padrão-ouro para mensuração do turnout de bailarinos, de modo que esta costuma ser adaptada e escolhida de acordo com o objetivo de cada estudo.La técnica del ballet clásico exige la realización máxima del en dehors o turnout, caracterizado por la rotación externa de miembros inferiores.

Esta revisión presenta una fuerte evidencia para afirmar que no hay, hasta el momento, un método o instrumento estándar-oro para la medición del turnout de bailarines, de modo que ésta suele ser adaptada y elegida de acuerdo con el objetivo de cada estudio.The classical ballet technique requires the maximum en dehors or turnout, which is the lower limbs external rotation. Considering its importance, several evaluation and measurement protocols have been proposed. This review aims to investigate systematically which methods were used to assess the classical dancers’ or classical ballet practitioners’ turnout. A systematic search was made in the Scopus, Science Direct, and PubMed databases in February 2016 for studies written in English that evaluated classical dancers or ballerinas, and the en dehors or turnout was measured. We found 593 articles, of which 25 were pre-selected for this review, featuring fifteen different methods and instruments for measuring turnout: kinemetry; inclinometer; Turnout Protractor, or protractor to measure the turnout; goniometer; dupuis tropometer; original protractor; subjects photos; rotational discs; Nicholas flexibility test; fleximeter; clinical drawing of the feet; subject standing on a piece of paper, or soil, or whiteboard; magnetic resonance; filming the subject during a sequence of dance steps; Dasco pro angle finder. This review rovides convincing evidence that there is not a method or gold-standard instrument for measuring dancers’ turnout, therefore such measurement is usually adapted and chosen according to each study objectives
