Comparison of noise indicators in an urban context

Inter-Noise 2016, 45th International Congress and Exposition of Noise Control Engineering, HAMBOURG, ALLEMAGNE, 21-/08/2016 - 24/08/2016Noise is a major environmental issue, which gave birth in the last decades to the development of many engineering methods dedicated to both its estimation and mitigation. The specificity of the noise pollution problem lies in the complexity of human hearing and subjective assessment, and in the high spatiotemporal variation and rich spectral content of the noise generated by a wide variety of sources in urban context. Indicators that encompass all these dimensions are required for the description of sound environments and for the evaluation of noise mitigation strategies. This paper compares usual and more specific indicators, dedicated to environmental noise analyses, by means of a literature review. The comparison is based on the three following criteria: i) the ability of indicators to describe and physically categorize the urban sound environments, ii) the relevance of indicators for describing the perceptive appreciations of urban sound environments, iii) the ability of indicators to be estimated through classical or more advanced traffic noise estimation models. A discussion compares the pro and cons of the selected indicators in an operational scop

Manutenção de software no Tribunal de Justiça de Goiás : emprego da DSR

Dissertação (Mestrado Profissional em Computação Aplicada) — Universidade de Brasília, Instituto de Ciências Exatas, Departamento de Ciência da Computação, Brasília, 2021.A tecnologia avança rapidamente e muitas mudanças são decorrentes dela. Conciliar as mudanças das regras de negócio com as mudanças nos sistemas se torna um desafio, e a urgência se torna uma regra. Assim, tomadas pelo senso de urgência, as equipes de de senvolvimento de sistemas se veem num ciclo de manutenções urgentes e intermináveis. No setor público, as mudanças chegam mais lentamente, mas os desafios se esbarram numa gestão consolidada durante décadas de trabalhos não automatizados. As dificul dades em lidar com manutenção de software no Brasil se assemelham a outros países e a aplicação dos métodos ágeis pode diminuir ou solucionar problemas de manutenção em empresas públicas ou privadas. O Tribunal de Justiça de Goiás (TJGO) é um órgão do Poder Público Brasileiro que se destaca por sua prestação jurisdicional apoiada em tecnologia. Entretanto, a ausência de um processo bem definido de software colabora para desordem e retrabalhos que poderiam ser evitados. Neste contexto, o objetivo deste trabalho foi definir e avaliar a implantação de um processo de manutenção de software para o TJGO. A metodologia de pesquisa adotada é do tipo explicativa, com o emprego da técnica de pesquisa Design Science Research (DSR), que permite conduzir a pesquisa pela produção de artefatos tecnológicos capazes de transformar situações, alterando suas condições para estados mais desejáveis. Os resultados apontaram que, devido as peculiaridades do TJGO, foi necessário tratar as vertentes da manutenção e definir uma arquitetura de deployment e um processo sistemático. De acordo com a percepção dos envolvidos, observou-se melhora na gestão, no trabalho em equipe, no clima organizacional, e na velocidade das entregas.Por outro lado, estudos recentes elaborados por Mantovani e Marczak [1] apontam que desde os anos 2000, o Brasil vem aderindo cada vez mais aos métodos ágeis, como indica a Figura 2.1, prática que se observa pelo mundo todo como uma das principais formas de inovação digital. Thus, taken by the urgency sense, the systems development teams enter in a loop of urgent and endless maintenance. In the public sector, the changes becomes more slowly, but the challenges add up to a consolidated management during decades of non-automated work. The difficulties to deal with software maintenance in Brazil are similar to other countries, but there are scientific consensus that the application of agile methods can reduce or solve maintenance problems in public or private companies. The Goiás Court of Justice (TJGO) is an organ of the Brazilian Public Power that stands out for its jurisdictional provision that is supported by several technology tools. However, the lack of a well-defined software process, contributes to rework that could be avoided. In this context, the objective of this work was to define and evaluate the implementation of a software maintenance process for TJGO. The research methodology adopted is explanatory type, with the use of the Design Science Research (DSR) tech nique, that allows to drive the research by technologics artifacts that enable to transform situations, to change their conditions to more desirable states. The the results indicate that, because of TJGO peculiarities, it was necessary to work the maintenance aspects and to define a deployment architecture, and define a systematic process. According to the perception of involved stakeholders, it was possible to observe to be observed man agement improvements, teamwork improvements, organizational climate improvements, and more speed of deliveries

A port by any other name: a preliminary spatial analysis of ancient infrastructural landscapes and settlement organization at Macurany, Brazil

Complex human-environmental processes form identifiable, lasting features on the landscape that can illuminate past human behavior and human-environment interactions. We examine the anthropogenic landscape of the ancient port of Macurany, located along the middle Amazon River in Parintins, Brazil, and identify four classes of anthropogenic landscape features at the site: wharfs, middens, terra preta (dark or black earths), and cultural forests. Middens, terra preta, and cultural forests have been found at archaeological sites in regions surrounding Macurany, but wharfs have not previously been reported in Amazonian contexts predating European contact. Taken together, these features are clearly the result of anthropogenesis and represent a range of subsistence, settlement, and infrastructure-building activities pointing to an ancient society that was actively engaged in modifying the surrounding landscape for purposes beyond settlement and subsistence. Evidence for a permanent, extensive, continuously settled society practicing intensive landscape engineering in this region of Amazonia reinforces findings of dense habitation, infrastructure, and early urbanization in Amazonia prior to European contact. This research helps expand our understanding of human-environment interactions, landscape formation processes, and settlement organization in ancient Amazonia.University of Louisville to Anna T.

On the magnetically driven ferroelectric phase in GdMnO3

At room temperature, GdMnO3 is a paraelectric and paramagnetic with a distorted perovskite structure of orthorhombic symmetry (space group Pnma). On cooling, it undergoes a phase transition sequence to a magnetic incommensurate phase (k=delta a*; Tc1=42K) and a A-type antiferromagnetic phase (Tc2=27K). At low temperatures (T<12K), a magnetic field applied along the a-axis destabilizes the antiferromagnetic phase and induces a first order transition to a magnetic commensurate modulated phase (delta=1/4) that is also ferroelectric (P//c). This work analyses this field induced phase transition from the point of view of the symmetry and Landau theory.Comment: 13 pages, communication to the 11th European Meeting on Ferroelectricity, Bled (Slovenia)2007; submitted to Ferroelectric

O princípio esperança e o movimento de multidão de 2013

In this article we investigated the importance of the expectant affection hope for the multitude movement that started in 2013 in the city of Porto Alegre/RS. Our main goal is to investigate the manner in which hope motivated the protesters’ actions and structured the manifestations. This goal seeks to answer the following question: how did hope motivated the 2013 manifestations in the city of Porto Alegre? Our methodology is qualitative, in which we used the analysis of journalistic photographic records of the 2013 manifestations – collected on news websites. We found, from that, that hope had crystallized in the factual reality, motivating the protesters to act through iconoclastic and softs practices, made it possible for the acts to intensify after the police repressions, connected the protesters intersubjectively around utopian objects and caused the temporary transfer of the social front from the interior of the state to the streets of the city.Keywords: Hope. Multitude movement. 2013 manifestations.No presente artigo, investigamos a importância do afeto expectante esperança para o movimento de multidão deflagrado no ano de 2013 na cidade de Porto Alegre/RS. Nosso principal objetivo é investigar o modo pelo qual a esperança motivou as ações dos manifestantes e estruturou as manifestações. Tal objetivo busca responder a seguinte questão: de que modo a esperança motivou as manifestações de 2013 na cidade de Porto Alegre? Nossa metodologia é qualitativa, na qual nos valemos da análise de registros fotográficos jornalísticos das manifestações de 2013 coletados em websites de notícias. Verificamos, a partir disso, que a esperança se cristalizou na realidade fática, motivando os manifestantes a agirem através de práticas iconoclastas e softs, o que possibilitou o recrudescimento dos atos após as repressões policiais, conectou os manifestantes intersubjetivamente em torno de objetos utópicos e provocou a transferência temporária do front social do interior do Estado para as ruas.Palavras-chave: Esperança.

Private governance in royalty collection: Effectiveness and limitations in tracing GM soybean in Brazil

Ce papier analyse l'émergence d'une innovation institutionnelle en accompagnement de la diffusion du soja génétiquement modifié au Brésil. Il en découle une gouvernance plutôt efficace par la création d'une situation gagnant-gagnant pour les acteurs impliqués, au moins à court terme, tant que la coexistence avec les variétés conventionnelles peut demeurer. Cette coexistence est menacée surtout du fait d'une absence de prime de marché pour le soja conventionnel.OGM; soja; Brésil; innovation institutionnelle; redevance d'emploi; coexistence

Semiclassical Propagation of Wavepackets with Complex and Real Trajectories

International audienceWe consider a semiclassical approximation, first derived by Heller and coworkers, for the time evolution of an originally Gaussian wave packet in terms of complex trajectories. We also derive additional approximations replacing the complex trajectories by real ones. These yield three different semiclassical formulae involving different real trajectories. One of these formulae is Heller's thawed Gaussian approximation. The other approximations are non-Gaussian and may involve several trajectories determined by mixed initial–final conditions. These different formulae are tested for the cases of scattering by a hard wall, scattering by an attractive Gaussian potential and bound motion in a quartic oscillator. The formula with complex trajectories gives good results in all cases. The non-Gaussian approximations with real trajectories work well in some cases, whereas the thawed Gaussian works only in very simple situations
