Development and/or change of the notion of permanent object and operative causality: Empirical evidence in the frst year of life
(Fundacion para el Avance de la Psicologia, 2013)
This study examines the notion of permanent object during the first year of life, taking into account the controversy of two approaches about the nature of change: developmental change and cognitive change. Using a ...
Static secure page allocation for light-weight dynamic information flow tracking
(2012)
Dynamic information flow tracking (DIFT) is an effective security countermeasure for both low-level memory corruptions and high-level semantic attacks. However, many software approaches suffer large performance degradation, ...
Supplier selection service-case study UTB
(2012)
Supplier selection supported by methods based on computational tools are fundamental enterprise actions. This paper proposes the development of supplier selection model supported on a computational tool, using the purchasing ...
Organic versus conventional: A comparative study on the shelf life of passion fruit (Passiflora edulis Sims) crops
(Universiti Putra Malaysia, 2019)
Yellow passion fruit (Passiflora edulis Sims) is one of the most appetising fruits worldwide due to its intense flavour. There have been few published studies comparing the evolution of storage quality parameters and shelf ...
Determination of the Voltage Stability Index in DC Networks with CPLs: A GAMS Implementation
(Springer, 2019)
This paper addresses the voltage collapse analysis in direct-current (DC) power grids via nonlinear optimization approach. The formulation of this problem corresponds to an optimization problem, where the objective function ...
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 ...
