39. Estudo de modelos e condições iniciais da geração a priori de detritos espaciais e sua propagação orbital / Study of models and initial conditions of a priori generation of space debris and their orbital propagation
Currently, it is estimated that there are hundreds of thousands of space debris, of various sizes, around the Earth. The space debris, also known as orbital debris, can remain in orbit with other bodies for a long time; and can cause risks of collision, including with space vehicles still in operation. In addition, there are risks of potential accidents by r

41. Probabilistic approach for yield analysis of dynamic logic circuits
In deep-submicrometer technologies, process variability challenges the design of high yield integrated circuits. While device critical dimensions and threshold voltage shrink, leakage currents drastically increase, threatening the feasibility of reliable dynamic logic gates. Electrical level statistical characterization of this kind of gates is essential for

42. Disponibilidade de bebidas alcoólicas e beber e dirigir
Alcohol abuse and traffic crashes (TC) are considered public health problems and every year they are associated with 2.5 and 1.2 million of deaths worldwide, respectively. Alcohol outlet (AO) density has been associated with Driving Under Influence (DUI), which is a well known risk factor for TC. However, the association is controversial in international lit

44. Sampling studies to estimate the HIV prevalence rate in female commercial sex workers
INTRODUCTION: We investigated sampling methods being used to estimate the HIV prevalence rate among female commercial sex workers. METHODS: The studies were classified according to the adequacy or not of the sample size to estimate HIV prevalence rate and according to the sampling method (probabilistic or convenience). RESULTS: We identified 75 studies that

45. Application of Bayesian Networks in the human error contribution analysis of collision accidents. / Aplicação de Redes Bayesianas na análise da contribuição do erro humano em acidentes de colisão.
Recently, in the naval industry, the normalization of classification societies and IMO (International Maritime Organization) has presented a gradual change, going from prescriptive procedures to a regulatory structure based on risk. That perspective offers some advantages to operators and constructors: 1) greater capacity to incorporate innovations in design
