Energy flow and network analysis of Terminos Lagoon, SW Gulf of Mexico
(Journal of Fish Biology, 1998)
The food web in Terminos Lagoon, south-western Gulf of Mexico was dominated by the detrital pathway, with benthic invertebrates playing a significant role in transferring energy from detritus to higher trophic levels. The ...
The global non-entropic arrow of time: from global geometrical asymmetry to local energy flow
(Springer, 2009-03)
Since the nineteenth century, the problem of the arrow of time has been
traditionally analyzed in terms of entropy by relating the direction past-to-future to
the gradient of the entropy function of the universe. In this ...
Previsão de vazões de afluência para o setor elétrico por meio de modelos lineares e não lineares
(Universidade Federal de Santa MariaBREngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de Produção, 2013-07-24)
The theme of this research is the use of prediction models of Integrated Autoregressive and type of moving average- ARIMA, along with the Autoregressive models of Conditional Heterokedastic-ARCH. The first class of models ...
Combined control of a flywheel energy storage system and a vanadium redox flow battery for wind energy applications in microgridsControl combinado de un sistema de almacenamiento de energía flywheel y una batería de flujo redox de vanadio para aplicaciones de energía eólica en microredes
(Universidad Nacional de Colombia, 2017-09)
The incorporation of wind generation in microgrids is growing progressively. This integration can introduce problems in the dynamics and power quality of the electrical system due to the wind fluctuations. This work proposes ...
Performances of two pilot decentralized wastewater treatment plants used to treat low-strength wastewater
(2017-10-01)
The performances of an anaerobic/aerobic baffled reactor (AABR) and a horizontal subsurface flow constructed wetlands (HFCW) have been investigated. In this study, both systems were operated in parallel using the same ...
Hybrid Stochastic/Information Gap Decision Theory Model for Optimal Energy Management of Grid-Connected Microgrids with Uncertainties in Renewable Energy Generation and Demand
(2021-01-01)
Microgrids (MGs) are considered a reliable solution for the integration of a high level of intermittent distributed energy resources. However, renewable energy generation has added complexity to the optimal energy management ...
An integrated supply-demand model for the optimization of energy flow in the urban system
(Elsevier Sci Ltd, 2016-02-15)
This research aims to develop a bottom-up integrated supply-demand model to assess the optimal performance of urban energy systems. To this end, an optimization model founded on the principles of microeconomics was developed ...
Transient non-Darcy forced convective heat transfer from a flat plate embedded in a fluid-saturated porous medium
(1990-09-01)
Transient non-Darcy forced convection on a flat plate embedded in a porous medium is investigated using the Forchheimer-extended Darcy law. A sudden uniform pressure gradient is applied along the flat plate, and at the ...

Capacidade de carga real (ccr) da caverna de santana, parque estadual turístico do alto ribeira (Petar) - sp, e indicações para o seu manejo turístico
(2008-12-01)
The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical ...
