Pronoun-dropping or zero anaphora in translation from german into portuguese

In this article I will analyse anaphoric references in German texts and their transaltion into Portuguese. I will take as main corpus Heinrich Böll's novel Haus ohne Hüter and its translation into Portuguese by Jorge Rosa with the title Casa Indefesa. I will concentrate on the use of personal pronouns and possessives in references to both people and objects in source text and target text and I will present patterns of symmetries and asymmetries. I will claim that asymmetries in the translation of such anaphoric references can be accounted for mainly by differences in the pronominal systems and verbal systems of both languages and by differences in the way each language marks theme/topic continuity/discontinuity in discourse. Issues related to style and the translation of anaphors will also be addressed. I will finally raise some questions related to ambiguous references which can not be solved within the scope of syntax or semantics, thus requiring pragmatic interpretation based on cultural knowledge/world knowledge.

Caracterização dos consumos energéticos e estudo do potencial de melhoria da eficiência energética em edifícios de escritórios

A forte preocupação ambiental, nomeadamente a emissão de Gases com Efeito de Estufa (GEE), aliada à constante ameaça do esgotamento dos combustíveis de origem fóssil, leva à necessidade de consumir energia de forma mais eficiente. Neste sentido, surge a promoção da eficiência energética nos diversos sectores consumidores de energia em todo o Mundo. Sabendo que passamos mais de 80% do nosso tempo dentro de edifícios, e que cerca de 40% da energia mundial é consumida nos mesmos [ADENE], é importante operar no sentido de promover a utilização racional de energia e incentivar ao consumo eficiente da mesma nos edifícios. Apesar do esforço que tem sido realizado a nível nacional, no sentido de melhorar a eficiência energética em edifícios de serviços, através da implementação de legislação diversa e de vários programas de incentivo, existem ainda várias lacunas a serem colmatadas e muito trabalho a fazer nesse sentido. Por tudo isto, e principalmente por ter constantemente em mente premissas como “a energia mais barata é aquela que não se consome” ou “não podemos gerir aquilo que não medimos”, surgiu a ideia de realizar esta dissertação, onde inicialmente através de dados provenientes de telecontagem se desenvolve uma tentativa de padronização/tipificação do consumo eléctrico em seis edifícios de escritórios, identificando-se assim algumas situações anómalas em diversos diagramas de carga construídos. Relaciona-se também o consumo eléctrico dos seis edifícios com algumas variáveis exógenas, de modo a perceber a influência das mesmas no consumo eléctrico de cada edifício. Numa vertente mais prática, foram identificadas e quantificadas potenciais medidas de melhoria, comportamentais e técnicas, num dos edifícios em estudo, de modo a poder contribuir para a redução do consumo energético do mesmo. Espera-se que este trabalho, possa eventualmente constituir uma ajuda na caracterização de consumos e detecção de medidas de melhoria em edifícios de escritórios, alcançando a eficiência energética neste tipo de instalações e facilitando assim o trabalho de vários profissionais do sector. Pretende-se igualmente demonstrar a importância da eficiência energética na gestão do uso da energia eléctrica em edifícios, e efectuar um paralelo entre a energia economizada por meio da implementação de medidas/acções de uso racional e eficiente, com a redução da queima de combustíveis fosseis na geração de energia eléctrica e a sua consequente redução nas emissões de dióxido de carbono (CO2), com o objectivo final de melhorar a qualidade de vida no nosso planeta.

Analysis of diffusion process in fractured reservoirs using fractional derivative approach

The fractal geometry is used to model of a naturally fractured reservoir and the concept of fractional derivative is applied to the diffusion equation to incorporate the history of fluid flow in naturally fractured reservoirs. The resulting fractally fractional diffusion (FFD) equation is solved analytically in the Laplace space for three outer boundary conditions. The analytical solutions are used to analyze the response of a naturally fractured reservoir considering the anomalous behavior of oil production. Several synthetic examples are provided to illustrate the methodology proposed in this work and to explain the diffusion process in fractally fractured systems.

Symmetry and order parameter dynamics of the human odometer

Bipedal gaits have been classified on the basis of the group symmetry of the minimal network of identical differential equations (alias cells) required to model them. Primary bipedal gaits (e.g., walk, run) are characterized by dihedral symmetry, whereas secondary bipedal gaits (e.g., gallop-walk, gallop- run) are characterized by a lower, cyclic symmetry. This fact has been used in tests of human odometry (e.g., Turvey et al. in P Roy Soc Lond B Biol 276:4309–4314, 2009, J Exp Psychol Hum Percept Perform 38:1014–1025, 2012). Results suggest that when distance is measured and reported by gaits from the same symmetry class, primary and secondary gaits are comparable. Switching symmetry classes at report compresses (primary to secondary) or inflates (secondary to primary) measured distance, with the compression and inflation equal in magnitude. The present research (a) extends these findings from overground locomotion to treadmill locomotion and (b) assesses a dynamics of sequentially coupled measure and report phases, with relative velocity as an order parameter, or equilibrium state, and difference in symmetry class as an imperfection parameter, or detuning, of those dynamics. The results suggest that the symmetries and dynamics of distance measurement by the human odometer are the same whether the odometer is in motion relative to a stationary ground or stationary relative to a moving ground.

Comparing the performance of geostatistical models with additional information from covariates for sewage plume characterization

In this work, kriging with covariates is used to model and map the spatial distribution of salinity measurements gathered by an autonomous underwater vehicle in a sea outfall monitoring campaign aiming to distinguish the effluent plume from the receiving waters and characterize its spatial variability in the vicinity of the discharge. Four different geostatistical linear models for salinity were assumed, where the distance to diffuser, the west-east positioning, and the south-north positioning were used as covariates. Sample variograms were fitted by the Mat`ern models using weighted least squares and maximum likelihood estimation methods as a way to detect eventual discrepancies. Typically, the maximum likelihood method estimated very low ranges which have limited the kriging process. So, at least for these data sets, weighted least squares showed to be the most appropriate estimation method for variogram fitting. The kriged maps show clearly the spatial variation of salinity, and it is possible to identify the effluent plume in the area studied. The results obtained show some guidelines for sewage monitoring if a geostatistical analysis of the data is in mind. It is important to treat properly the existence of anomalous values and to adopt a sampling strategy that includes transects parallel and perpendicular to the effluent dispersion.
