Abstract (sommario):
Long distance repeaterless optical fiber communications systems are currently used to transmit most internet and telephone information worldwide. The growth of photonic telecommunications technology has produced systems with very high bit-rate per fiber, but this still falls short of its potential capacity. Currently systems that are able to transmit even higher bit-rates are being developed utilizing dense wavelength-division-multiplexing (WDM) to maximally utilize the bandwidth potential of optical fibers. One of the most important factors that limits the bit-rate achievable in a such a WDM

To begin with, the study considers why return dispersion changes over time. Given the influence of return dispersion on active portfolio return opportunity, it is important for managers to understand why return dispersion changes over time. For a sample of South African listed shares over the period June 1996 to December 2011, univariate time-series analysis reveals significant serial correlation in return dispers

Monte Carlo based statistical approach to solve Boltzmann Transport Equation (BTE) has become a norm to investigate heat transport in semiconductors at sub-micron regime, owing mainly to its ability to characterize realistically sized device geometries qualitatively.

The uncovered relations are robust to various endogeneity corrections and hence are likely causal.

Abstract (sommario):
Aujourd'hui, l'évaluation des conséquences environnementales et sanitaires d'événements majeurs liés aux rejets dans l'atmosphère de substances radiologiques ou chimiques est, de plus en plus, basée sur la mise en œuvre d'outils de modélisation. La capacité de ces outils à appréhender de manière toujours plus fine l'ampleur spatiale et temporelle de ce type d'événements contribue à leur positionnement croissant en appui aux situations d'urgence. Cependant, l'accident de Fukushima a souligné qu'en dépit de cette tendance, l'apport des outils n'est pas encore optimal au regard de l'environnement

Abstract (sommario):
The objective of this thesis is to analyze the effect of the transformation in the habitat that postfire salvage logging supposes on birds in Mediterranean pine forests, at different levels: species, community and ecosystem, focusing on the bird-mediated seed dispersal process. Salvage logging with commercial purposes is the main factor that determines the species composition after a fire, with the substitution of forest birds by open-habitat species, some of which hold an unfavourable conservation status in Europe. On the other hand, wood debris piles built by non-profitable burnt wood favour

CAPES<br>Este estudo teve por objetivo sugerir locais para o monitoramento da qualidade do ar no município de Paranaguá-PR. Para tal, foi utilizada modelagem matemática de dispersão de poluentes atmosféricos, associada ao levantamento de informações sobre adensamento populacional e distribuição de equipamentos urbanos nos bairros do município. Com o uso do software de modelagem AERMOD foram simuladas as concentrações de CO, NOX, SO2, PTS e HCT, considerando emissão veicular, industrial e do Porto de Paranaguá. Os dados meteorológicos utilizados nas simulações consistiram em uma série horária d

Abstract (sommario):
Las zonas costeras son uno de los ecosistemas que sufre mayor impacto antrópico a nivel mundial. La sobreexplotación de los recursos marinos es una de las actividades humanas que genera mayor impacto, reduciendo la abundancia y tamaño de las especies objetivo. Una de las medidas para proteger estos ecosistemas consiste en el establecimiento de áreas marinas protegidas. En Chile, el sistema actual de manejo de las pesquerías artesanales de especies bentónicas está basado en áreas parcialmente protegidas, las Áreas de Manejo y Explotación de Recursos Bentónicos (AMERBs), lo que ha supuesto una m

Abstract (sommario):
Em um cenário de aumento de competitividade, crescente expectativa por inovações do produto e necessidade de atender diferentes perfis de consumidores, o conceito de gerenciamento de cadeias de suprimentos globais (GSCM) surge como uma estratégia para coordenar mais eficazmente as atividades dispersas geograficamente dos sistemas produtivos. Na adoção do GSCM, as organizações devem lidar com rupturas que impactam no gerenciamento das suas atividades, tais como a interrupção de vias de transporte, pane no fornecimento de energia, desastres naturais e até ataques terroristas.

Abstract (sommario):
M.Ing.<br>In this dissertation the emphasis falls on the use of the 1550 run WDM systems that make use of standard single-mode fibre. The reason for this is that more than 50 million kilometres of standard telecommunication fibre is already installed in the worldwide telephone network. Therefore, from an economical point of view, the fourth generation of lightwave systems has to make use of this existing base. Using single-mode fibre at high bit-rate (- 10 Gb/s) dispersion becomes a problem. Furthermore, if amplifiers are used, as in the case of long-haul WDM systems, non-linear effects also b
