Infuěncia do relevo na produtividade e custos do harvester
(2010-03-01)
Among the several variables that influence timber harvesting is the slope, which influences the productivity of forest machines. In this experiment the harvester was evaluated technically and economically while cutting and ...
Energy landscapes shape animal movement ecology
(University Of Chicago Press, 2013-09)
The metabolic costs of animal movement have been studied extensively under laboratory conditions, although frequently these are a poor approximation of the costs of operating in the natural, heterogeneous environment. ...
An assessment of fiscal and regulatory barriers to deployment of energy efficiency and renewable energy technologies in Guyana
(ECLAC, 2014-02)
Guyana, like many CARICOM countries continues to depend on imported oil that fuels the electricity and transport sectors. Simultaneously, the high level of expenditure on oil reduces the financial resources available to ...
Optimization of a SAG mill energy system: integrating rock hardness, solar irradiation, climate change, and demand-side management
(Springer, 2020)
Integration of renewable energy into mining and processing operations is becoming necessary as part of a strategy towards sustainability in the minerals industry. A solar photovoltaic plant along with a battery energy ...
Estudo da implantação de um sistema de captação de energia solar em residência unifamiliar.
(Grupo de Pesquisa Virtuhab/ UFSC, 2017-05-03)
Among several sustainability guidelines is the use of clean and renewable energies, that is, they do
not leave residues and are economically viable. In this scenario is the capture of solar energy which
is a way of ...
Optimal volt-VAr control operation for energy cost reduction in distribution systems considering a voltage dependent load model
(2017-01-04)
In this paper, a new mixed integer linear programming formulation is proposed to optimally control the Volt-VAr control devices installed in a balanced electrical distribution system (EDS), taking into account the presence ...
