Análisis de la evolución de tráfico de graneles líquidos al APB : En los últimos 10 años
El objetivo principal de este trabajo es desarrollar un proyecto relacionado con las terminales portuarias, en concreto las que manipulan mercancías peligrosas, ya que es el sector al cual me quiero dedicar en un futuro no lejano. Así pues, decidí estudiar la situación actual del puerto Energético de Barcelona, ya que es uno de los puertos más importantes del mediterráneo y tenerlo cerca es una gran oportunidad para conocer las instalaciones necesarias para el manejo de cargas peligrosas
Dificuldades e obstáculos no aprendizado de trigonometria : um estudo com alunos do ensino médio do Distrito Federal
Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Exatas, Departamento de Matemática, Programa de Mestrado Profissional em Matemática em Rede Nacional, 2018.Tendo em vista a importância da trigonometria para o desenvolvimento das ciências exatas, essa pesquisa procura identificar, dentro desse tema, os principais erros e/ou dificuldades apresentados por alunos do 2o ano do ensino médio matriculados em escolas públicas do Distrito Federal. Trata-se de uma pesquisa exploratória de caráter misto, cuja parte quantitativa _e feita a partir de um questionário de múltipla escolha sobre trigonometria e temas correlatos, e a parte qualitativa e feita por meio de entrevistas com alunos que participaram da parte quantitativa da pesquisa. O estudo mostra que as dificuldades permeiam todos os ramos da trigonometria, e destacam-se dificuldades em relação à definição de radiano, a propriedades, características e comportamentos das funções trigonométricas e a conexão entre o círculo trigonométrico e as funções trigonométricas pela função de Euler.Coordenação de Aperfeiçoamento Pessoal de Nível Superior (Capes).In view of the importance of trigonometry for the development of exact sciences, this research aims at identifying the main errors and / or difficulties experienced in this subject contents by sophomores students enrolled in Federal District' schools. It is an exploratory research of mixed character whose quantitative part is made from a multiple choice questionnaire about trigonometry and related topics. The qualitative part of the research is built on interviews with students who answered the questionnaire of the quantitative part. The study shows that the students experienced difficulties in all the branches of trigonometry and particularly in dealing with the definition of radian, the properties, characteristics and behaviors of the trigonometric functions as well as with the connection between the trigonometric circle and the trigonometric functions through Euler's function
A quantitative examination of lightning as a predictor of peak winds in tropical cyclones
We use the World Wide Lightning Location Network to investigate lightning strike variations in 8 years of categories 4 and 5 tropical cyclones. A cross‐correlation analysis is performed between the lightning and maximum sustained wind variations, giving lag and lead times related to the peak linear correlation for each tropical cyclone. A previous study of 58 cyclones by Price et al. (2009) is reexamined using the International Best Track Archive for Climate Stewardship database for the maximum sustained wind speeds of each tropical cyclone showing a moderate to strong correlation between lightning and wind variations. An 8 year data set of 144 tropical cyclones are analyzed in the same way, with a 10° square window, giving similar results to the smaller data set. Using a radial lightning collection window of < 500 km, we confirm the general results of previous studies that lightning can be used on a ∼1 day timescale to predict the evolution of the winds in tropical cyclones. Investigation of different lightning collection window sizes indicates that the lightning lead times are highly dependent upon the window size. Smaller collection windows have modal lightning lead times of ∼2.75 and 0 days, indicating that the lightning location inside the cyclone is as important as the total lightning variation. We have also performed a fixed time lag correlation which shows that preexisting knowledge of what time lag to use is needed in order to use this approach as a predictive tool

35th International Viola Congress
Extent: 43 Concerts and Lecture Demonstrations Parts of this event were broadcast on a selection of programs by the Australian Broadcasting Commission FM. All events that were part of the Congress were recorded and published as a CD. The University of Adelaide and the Arts Council of New Zealand were major sponsors for this event. The congress was also supported by the Australia Council and SA Department of Arts, as well as the New Zealand Symphony Orchestra, Jane Newbery Design and Sheila Bryce Publicity. With Australian premieres of: Testament for 12 Violas / Brett Dean (AU), performed by Viola Viva (NZ); ‘Prologue’ for viola and resonators / Gerard Grisey, performed by William Lane (AU); ‘This is why people OD on pills and jump off the Golden Gate bridge' / Jennifer Walsh; Sonata for Viola and Piano / Charles Stamford, performed by Hartmutt Lindemann (Ger) and Ben Martin (AU)The congress included the following new works:
Sonata for Viola and Piano / Alan Belkin (Can), performed by Jutta Puchammer Sedillot (Can) and Larissa Schneider (SA); Cadenza for Viola Solo / Martin Lodge (Can), performed by Timothy Deighton (US); ‘Odyssey’ for Viola and Piano / Roger Vogel (US), performed by Mark Neumann (US) and En-Chi Ho (US); ‘Work for Viola and Electronics’ / Samson Young, performed by William Lane (AU); Øya ii: liv (the island ii:life) / Jennifer Walsh; Concerto for Viola and Orchestra / Charles Bodman Rae (commissioned new work), performed by Jurg Dahler (Switzerland) with Congress Chamber Orchestra conducted by Keith Crellin; ‘Wedding Mobile” / Colin Spiers (AU), performed by Deborah Lander (AU) and David Brunell (US
