A bottom-up robot architecture based on learnt behaviors driven design
(2015-06-17)In reactive layers of robotic architectures, behaviors should learn their operation from experience, following the trends of modern intelligence theories. A Case Based Reasoning (CBR) reactive layer could allow to achieve ... -
A Brain–Computer Interface Speller with a Reduced Matrix: A Case Study in a Patient with Amyotrophic Lateral Sclerosis
(2014-06-03)Visual P300-based Brain–Computer Interface (BCI) paradigms for spelling are aimed at offering a non-muscular communication channel for those people with severe motor impairment, such as locked-in patients. To be as effective ... -
A comparative study of the evolution of tourism policy in Spain and Portugal
(2014-05-08)The purposes of this study are to analyze and compare the way in which tourism policy has evolved in Spain and Portugal. Our study covers an extensive period of time, enabling the similarities and differences between the ... -
A Comparison of a Brain-Computer Interface and an Eye Tracker: Is There a More Appropriate Technology for Controlling a Virtual Keyboard in an ALS Patient?
(Springer, 2017)The ability of people affected by amyotrophic lateral sclerosis (ALS), muscular dystrophy or spinal cord injuries to physically interact with the environment, is usually reduced. In some cases, these patients suffer from ... -
A Dangerous Liaison? Libertarianism, Sustainability, and Ecological Citizenship.
(2014-04-22)La comunicación versa sobre la relación entre la sostenibilidad ecológica y la sociedad liberal. Más concretamente, explora la compatibilidad de ambos y la utilidad que algunas herramientas de la filosofía libertaria puede ... -
A Decision Tree and S-Transform Based Approach for Power Quality Disturbances Classification
(2013-06-28)In this paper, it is presented an automated classification based on S-transform as feature extraction tool and Decision Tree as algorithm classifier. The signals generated according to mathematical models, including complex ... -
A duopoly game under uncertainty about product differentiation: A separating or pooling equilibrium?
(2016-11-14)This article analyses price competition in a two-period duopoly model in which only one firm knows the degree of substitutability between products. Using a Hotelling model, we analyse the informed firm´s incentive to reveal ... -
A general approach for robust integrated polarization rotators
(International Society for Optics and Photonics, 2013)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
A generalized framework to consider positive and negative attributes in formal concept analysis
(2014-10-23)In Formal Concept Analysis the classical formal context is analized taking into account only the positive information, i.e. the presence of a property in an object. Nevertheless, the no presence of a property in an object ... -
A Linda-based Platform for the Parallel Execution of Out-place Model Transformations
(2017)Context: The performance and scalability of model transformations is gaining interest as industry is progressively adopting model-driven techniques and multicore computers are becoming commonplace. However, existing model ... -
A logic-based approach to compute a direct basis from implications
(2014-09-19)Formal Concept Analysis is an emergent area in the topic of data analysis based on lattice theory. In this framework, a context is defined as the relation between a set of objects and a set of attributes and from here it ... -

A methodology to find the elementary landscape decomposition of combinatorial optimization problems
(2014-10-03)A small number of combinatorial optimization problems have search spaces that correspond to elementary landscapes, where the objective function f is an eigenfunction of the Laplacian that describes the neighborhood structure ... -
A New Framework for the Performance Analysis of Wireless Communications under Hoyt (Nakagami-q) Fading
(IEEE, 2017)We present a novel relationship between the distribution of circular and non-circular complex Gaussian random variables. Specifically, we show that the distribution of the squared norm of a non-circular complex Gaussian ... -
A New Multi-Objective Approach for Molecular Docking Based on RMSD and Binding Energy
(2016-07-12)Ligand-protein docking is an optimization problem based on predicting the position of a ligand with the lowest binding energy in the active site of the receptor. Molecular docking problems are traditionally tackled with ... -
A Phoenician Way to be Roman
(2017-04-04)This paper offers a synthesis on my dissertation, titled The Phoenician communities of the Iberian Peninsula and their integration in the Roman world: an identity perspective. The period under discussion extends from the ... -
A Proposal for the Restoration of the Islamic Towers in the Segura de la Sierra Valley. Significance and Values of this Cultural Landscape
(2014-04-10)Due to the strategic position of Segura de la Sierra valley (Jaén, Spain) during the 12th and 13th centuries, there were built several defensive fortresses both by Muslims and Christians. As a result, there are still remains ... -
