Heuristic approach for optimal location and sizing of distributed generators in AC distribution networks
(World Scientific and Engineering Academy and Society, 2019)
This paper addresses, from a heuristic point of view, the problem of the optimal location and sizing of distributed generators (DGs) in alternating-current distribution networks with radial topology. A master–slave ...
A case study approach to introduce circular economy in sustainable design education
(Institution of Engineering Designers, The Design Society, 2019)
Finding sustainable solutions to worldwide problems has become a critical challenge for engineers. The use of natural resources and the generation of materials now degradable should be controlled when sustainable solutions ...
Integration of energy storage systems in AC distribution networks: Optimal location, selecting, and operation approach based on genetic algorithms
(Elsevier Ltd, 2019)
This paper presents a method to find the optimal location, selection, and operation of energy storage systems (ESS- batteries-) and capacitors banks (CB) in distribution systems (DS). A mixed-integer non-linear programming ...
Implementation of an image based focusing algorithm for non-mydriatic retinal imaging
(Institute of Electrical and Electronics Engineers Inc., 2014)
Retinal photography is important for the assessment of eye diseases. The task of fine focusing the image is demanding and lack of focus is often the cause of suboptimal photographs. The advent of digital cameras has provided ...
Moral sentiment and reason: The notion of justice in Adam Smith and Amartya Sen
(Universidad Nacional de Colombia, 2014)
Amartya Sen argues that his notion of justice has its origins in the thinking of Adam Smith. Sen employed, in a very particular way, the concepts of sympathy and the impartial spectator. Beyond the statement of Sen, we are ...
Retinal image analysis oriented to the clinical task

Steric and chain length effects in the (√(3) × √(3))R30° structures of alkanethiol self-assembled monolayers on Au(111)
(Wiley-VCH Verlag, 2011)
The translational and orientational potential energy surfaces (PESs) of n-alkanethiols with up to four carbon atoms are studied for (√(3) × √(3))R30° self-assembled monolayers (SAMs). The PESs indicate that methanethiol ...
Comparison of adsorption of mercaptopropyltrimethoxysilane on amphiphilic TiO 2 and hydroxylated SiO 2
(2010)
Alkylsilane 3-mercaptopropyltrimethoxysilane (3MPT) monolayers with a functional end group -SH were used to immobilize Ag colloidal nanoparticles on photoinduced amphiphilic TiO 2 and hydroxylated SiO 2 surfaces. The ...
Risky tax shields and risky debt: An exploratory study
(2010)
This article (1) identifies three sources of risk for tax shields (TS): Two of them are associated with debt risk and one is associated with operating risk. (2) A set of conditions for defining risky debt associated with ...
Technology and market conditions toward a new competitive landscape in the wireless access market
(2010)
This article argues that the wireless telecommunication market is about to witness a shift in business models and market structure as a result of the deployment of new broadband access technologies, spectrum management ...
