(ECLAC, 2016-05)
The objective of this study is to research barriers to the identification and implementation of mechanisms for enhancing energy efficiency and investment in renewable energy in the Caribbean. Specifically the study aims ...
The influence of specific mechanical energy on cornmeal viscosity measured by an on-line system during twin-screw extrusion
(Brazilian Society of Chemical Engineering, 1999)
Solar energy policy to boost Brazilian power sector
(2020)
Purpose: The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ...
Energy exchange in globally coupled mechanical phase oscillators
(American Physical Society, 2020-07)
We study the stationary dynamics of energy exchange in an ensemble of phase oscillators, coupled through a mean-field mechanical interaction and added with friction and an external periodic excitation. The degree of ...
Pellets prepared with mechanically activated iron ore
(WILEY-BLACKWELL, 2008)
This work analyses pellets prepared with iron ore that has been mechanically activated by high energy ball milling. Pellet feed iron ore was submitted to high-energy ball milling for 60 minutes, and the resulting material ...
Habitat specificity can blur the predictions of species-energy theory: A case study of tenebrionid beetles adapted to aridity
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
Species-energy theory predicts a positive relationship between species richness and energy. The mechanism assumed by this theory is that high energy promotes high population abundance, which in turn promotes high species ...
Implementación de un modelo predictivo para la estimación de un indicador de borehole quality, mediante la metodología machine learning, en los pozos perforados durante la campaña 2017-2020 de dos campos de hidrocarburos de la Cuenca del Valle Medio del Magdalena
(Fundación Universidad de América, 2021-07-29)
El documento presenta la implementación de un modelo predictivo para la estimación de un Borehole Quality, dicho proyecto de investigación nació a partir de la necesidad de tener valores o rangos de parámetros estandarizados ...
Influence of the tool edge geometry on specific cutting energy at high-speed cutting
(2007-07-01)
This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle ...
