Implicit large-eddy simulation of the stratocumulus-topped boundary layer: A grid sensitivity study
No full textA range of implicit large-eddy simulations of the stratocumulus-topped boundary layer is performed to study the influence of grid resolution on selected parameters including liquid water path and second and third moments of vertical velocity fluctuations. The simulations are based on two sets of aircraft measurements, which are also used to evaluate the results of the simulations. The specific case presented here indicates that simulations with a grid aspect ratio accounting for the anisotropic nature of the turbulence near the surface and at the top of the boundary layer lead to better agreement with measurements than simulations with an isotropic grid
Lashing Out after Stewing over Public Insults: The Effects of Public Provocation, Provocation Intensity, and Rumination on Triggered Displaced Aggression
No full textFour studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face-saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression
Development of diagnostic and manipulation systems for space-charge dominated electron beams and confined electron plasmas in ELTRAP
No full textModifications have been implemented in the Penning-Malmberg device ELTRAP aimed
at performing studies on the dynamics of space-charge dominated nanosecond electron bunches traveling along the magnetic field. In particular, a Thomson backscattering apparatus has been developed where an infrared (IR) laser pulse collides with the bunched electron beam. The frequency-shifted
backscattered radiation, acquired by means of a photomultiplier (PMT), can be exploited to evaluate information on energy, energy spread and density of the bunch. The achievable sensitivity
of the diagnostics has been estimated, and valuable information on the main parameters affecting the signal-to-noise (S/N) ratio has been obtained [B. Paroli, F. Cavaliere, M. Cavenago, F. De Luca, M. Ikram, G. Maero, C. Marini, R. Pozzoli, and M. Romé, JINST 7, P01008 (2012)]. A series of upgrades are under way, aimed at increasing the S/N ratio through the use of a new laser for the electron source, the insertion of a stray light shield, and the optimization of the detection electronics. Moreover, electromagnetic simulations relevant to the design and implementation of a microwave
heating system are presented. The generation of an electron plasma in ELTRAP by means of a low-power radio frequency (RF) drive in the MHz range applied on one of the trap electrodes and under ultra-high vacuum (UHV) conditions has previously been demonstrated [B. Paroli, F. De Luca,
G. Maero, F. Pozzoli, and M. Romé, Plasma Sources Sci. Technol. 19, 045013 (2010)]. The new heating system will allow the extension of the RF studies to the GHz range and in particular the
production of a more energetic electron plasma via cyclotron resonant excitation
Analysis of the two-dimensional turbulence in pure electron plasmas by means of advanced statistical techniques
No full textHighly magnetized, pure electron plasmas confined in a Penning-Malmberg trap allow one to perform experiments on the two-dimensional (2D) fluid dynamics under conditions where non-ideal effects are almost negligible. Recent results on the freely decaying 2D turbulence obtained from experiments with electron plasmas performed in the Penning-Malmberg trap ELTRAP are presented. The analysis has been applied to experimental sequences with different types of initial density distributions. The dynamical properties of the system have been investigated by means of wavelet transforms and Proper Orthogonal Decomposition (POD). The wavelet analysis shows that most of the enstrophy is contained at spatial scales corresponding to the typical size of the persistent vortices in the 2D electron plasma flow. The POD analysis allows one to identify the coherent structures which give the dominant contribution to the plasma evolution. The statistical properties of the turbulence have been investigated by means of Probability Density Functions (PDFs) and structure functions of spatial vorticity increments. The analysis evidences how the shape and evolution of the dominant coherent structures and the intermittency properties of the turbulence strongly depend on the initial conditions for the electron density

C. {\O}rsted InstituteUsing a projector formulation for the Van Vleck transform action, it is possible to go to tenth order without excessive effort. This is the -order needed to include sixth order centrifugal distortion in the effective vib-rot Hamiltonian for a state v. The Wilson-Howard Hamiltonian is first formulated as a Sum of ``scalar products”: \begin{equation} H=h_{2}{^{(0)}}+\kappa h_{3}{^{(0)}}+\kappa^{2}(h_{4}{^{(0)}}+h_{2}{^{(1)}}\cdot J{^{(1)}}+h_{0}{^{(2)}})+\kappa^{3}\ldots \end{equation} where denotes (n indices). The effective Hamiltonian is written similarly as: \begin{eqnarray} A_{v}&=&a_{2}{^{(0)}}+\kappa^{2}(a_{4}{^{(0)}}+a_{2}{^{(1)}}\cdot J{^{(1)}}+a_{0}{^{(2)}}\cdot J{^{(2)}})+\kappa^{4}(a_{6}{^{(0)}}+a_{4}{^{(1)}}\cdot J{^{(1)}}+a_{2}{^{(2)}}\cdot J{^{(2)}})\nonumber\\ &&+\kappa^{6}(..+a_{4}{^{(2)}}\cdot J{^{(2)}}+a_{2}{^{(3)}}\cdot J{^{(3)}}+a_{0}{^{(4)}}\cdot J{^{(4)}})\nonumber\\ &&+ \kappa^{8}(\ldots +a_{2}{^{(4)}}\cdot J{^{(4)}}+a_{0}{^{(5)}}\cdot J{^{(5)}})\nonumber\\ &&+\kappa{^{(10)}}(\ldots+ a_{0}{^{(6)}}\cdot J{^{(6)}})+.. \end{eqnarray} As an example has the form: (with symbols to be explained) \begin{equation} (a_{2}{^{(2)}})_{fg}=\{x(h_{2}{^{(1)}})_{f}: (h_{2}{^{(1)}})_{g}x +2xh_{3}{^{(0)}}: (h_{1} {^{(2)}}_.)_{fg}x+x(h_{2}{^{(2)}})_{fg}x\}_{H} \end{equation} This operator leads to and q-constants
Subtitling of collocational patterns in children's animated movies: a corpus-based study
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Inglês: Estudos Linguísticos e Literários, Florianópolis, 2015.Abstract : Due to technological innovations and to globalization, the translation of movies, or more specifically, audiovisual translation, has become an ever more common type of translation. However, most of the studies in the area focus on the technicalities involved in the activity, not taking into account the linguistic aspects of translation (Díaz Cintas & Remael, 2007). For that reason, little is known about the challenges and limitations of subtitling, and this area is constantly a target of criticism on its so called ?quality? (Carvalho, 2007). Following a descriptive approach (Toury, 2012), this research aims at uncovering the translation strategies (as defined by Chesterman, 1997; Pedersen, 2005; and Costa, 2014) used by subtitlers while rendering certain language patterns, namely collocations, from American English into Brazilian Portuguese. It takes on the methodological apparatus of corpus-based studies as they enable the processing of large quantities of data quickly and automatically. The corpus is made up of three children?s animated movies (Ice Age, Shrek and Toy Story), the subtitles of which were inserted in COPA-TRAD (Fernandes & Silva, 2013) ? a translation parallel corpus ? and analyzed following Pedersen?s (2005) classification of translation strategies for cultural expressions in subtitles. It was found that, most of the time, subtitlers will attempt to maintain the cultural expression in the translation or, at least, maintain its meaning, despite facing difficulties when dealing with puns and wordplay. In this sense, it can be attested that subtitlers were overall creative and innovative, possibly because of the movie genre they were working on ? animation. These results also show the unfounded nature of the criticism usually aimed this type of audiovisual translation.Graças aos avanços tecnológicos e à globalização, a tradução de filmes, ou mais especificamente, a tradução audiovisual, se tornou um tipo de tradução cada vez mais comum. No entanto, a maior parte das pesquisas feitas na área foca nas tecnicalidades envolvidas nessa atividade, sem levar em conta os aspectos linguísticos da tradução (Díaz Cintas e Remael, 2007). Por esse motivo, não se sabe muito sobre os desafios e as limitações da legendagem, e não raro esta área é alvo constante de críticas relacionadas à sua  qualidade (Carvalho, 2007). Seguindo uma abordagem descritivista (Toury, 1995), espera-se descobrir as estratégias de tradução (como definidas por Chesterman, 1997; Pedersen, 2005; e Costa, 2014) utilizadas por legendadores na tradução de determinados padrões linguísticos, ou colocações, do inglês americano para o português brasileiro. A metodologia aplicada é a dos estudos com base em corpus, já que estes permitem o processamento de grandes quantidades de dados de maneira rápida e automática. O corpus é composto por três filmes infantis de animação (A Era do Gelo, Shrek e Toy Story), cujas legendas foram inseridas no COPA-TRAD (Fernandes e Silva, 2013)  um corpus paralelo de tradução  e analisadas seguindo a classificação de estratégias de tradução de expressões culturais em legendas de Pedersen (2005). Descobriu-se que, na maioria das vezes, os legendadores tentam manter a expressão cultural na tradução ou, ao menos, manter seu significado, apesar de enfrentarem dificuldades ao lidarem com trocadilhos e jogos de palavras. Nesse sentido, pode-se afirmar que os legendadores foram em geral criativos e inovadores, possivelmente devido ao gênero dos filmes em que trabalharam  animação. Esses resultados mostram também a natureza infundada das críticas que são geralmente direcionadas a esse tipo de tradução audiovisual
