Simultaneous storm time equatorward and poleward large‐scale TIDs on a global scale
(American Geophysical Union, 2016-06-19)
We report on the first simultaneous observations of poleward and equatorward traveling ionospheric disturbances (TIDs) during the same geomagnetic storm period on a global scale. While poleward propagating TIDs originate ...
Large-scale biogas generation in Bolivia – A stepwise reconfigurationGeneración de biogás a gran escala en Bolivia: una reconfiguración gradualLarge scale biogas generation in Bolivia A stepwise reconfiguration
(Journal of Cleaner Production, 2018-04)
Renewable energy is well recognized not only as resource that helps to protect the environment for future generations but also as a driver for development. Waste-to-energy systems can provide renewable energy and also ...
Dynamic modelling and optimisation of cryogenic systems
(Pergamon-Elsevier Science Ltd, 2007-05)
This work addresses the dynamic optimisation of the cryogenic sector in a large-scale natural gas processing plant. Main attention is focused on rigorous dynamic modelling of countercurrent heat exchangers with phase change ...
Large-eddy simulation of an annular-sector duct rotating in parallel mode
(Universidade Tecnológica Federal do ParanáCuritibaBrasilMestrado em Engenharia Mecânica e de MateriaisUTFPR, 2018-05-03)
In this research the turbulent flow within an annular-sector duct rotating about a parallel axis is numerically solved using large-eddy simulation (LES). The study is motivated by the lack of in-depth understanding of the ...
The wealth gifted to the large-scale copper mining industry in Chile: new estimates, 2005-2014
(Naciones Unidas, 2018)
This article estimates the economic rents received by the 10 mines that comprise Chile’s
large-scale private-sector copper-mining industry. The methodology used produces a
conservative calculation and includes two ...
Influence of small-scale inhomogeneities on the cosmological consistency tests
(WILEY-BLACKWELLHOBOKEN, 2012)
The current cosmological dark sector (dark matter plus dark energy) is challenging our comprehension about the physical processes taking place in the Universe. Recently, some authors tried to falsify the basic underlying ...
