Multi-server approach for high-throughput molecular descriptors calculation based on multi-linear algebraic maps
(Wiley-VCH Verlag, 2015)The present report introduces a novel module of the QuBiLS-MIDAS software for the distributed computation of the 3D Multi-Linear algebraic molecular indices. The main motivation for developing this module is to deal with ... -
On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ... -
A Hooke's law-based approach to protein folding rate
(Academic Press, 2015)Kinetics is a key aspect of the renowned protein folding problem. Here, we propose a comprehensive approach to folding kinetics where a polypeptide chain is assumed to behave as an elastic material described by the ... -
Enhancing higher education experience: The eMadrid initiative at UNED university
(Institute of Electrical and Electronics Engineers Inc., 2015)In this paper we focus on the achievements of eMadrid initiative in some fields of technology-enhanced learning, mainly involving the improvement of the mechanisms for open educational content retrieval from Internet, ... -
Reduction of blooming artifacts in cardiac CT images by blind deconvolution and anisotropic diffusion filtering
(SPIE, 2015)Even though CT is an imaging technique that offers high quality images, limitations on its spatial resolution cause blurring in small objects with high contrast. This phenomenon is known as blooming artifact and affects ... -
Kinematic parameter estimation using close range photogrammetry for sport applications
(SPIE, 2015)In this article, we show the development of a low-cost hardware/software system based on close range photogrammetry to track the movement of a person performing weightlifting. The goal is to reduce the costs to the trainers ... -
Thermoeconomic analysis of wheat flour agroindustrial plant
(American Society of Mechanical Engineers (ASME), 2015)This paper presents the development of an exergy and thermoeconomic analysis of a wheat flour agro-industrial plant, which was aimed to evaluate the energy use and establish the operation cost of its components, and to ... -
Transient dynamic analysis of shear deformable shallow shells using the boundary element method
(Elsevier Ltd, 2015)The complexity involved in the dynamic response of plates brings many challenges from a mathematical standpoint. In this work, the transient dynamic analysis of elastic shallow shells under uniformly distributed pressure ... -
Elastodynamic analysis of thick multilayer composite plates by the Boundary Element Method
(Tech Science Press, 2015)Dynamic stress analysis of laminated composites plates represents a relevant task in designing of aerospace, shipbuilding and automotive components where impulsive loads can lead to sudden structural failure. The mechanical ... -
IMMAN: free software for information theory-based chemometric analysis
(Kluwer Academic Publishers, 2015)Abstract: The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is ... -
Conformastationary disk-haloes in Einstein–Maxwell gravity
(Springer New York LLC, 2015)An exact solution of the Einstein–Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the ... -
Novel global and local 3D atom-based linear descriptors of the Minkowski distance matrix: theory, diversity–variability analysis and QSPR applications
(Kluwer Academic Publishers, 2015)A new family of alignment-free 3D descriptors based on TOMOCOMD-CARDD framework has been designed, namely 3D-linear indices. In this report, we have proposed the use of a generalized form of the geometric pairwise atom-atom ... -
Direct power control of electrical energy storage systems: A passivity-based PI approach
(Elsevier Ltd, 2019)This paper proposes a direct power control for electrical energy storage systems (EESS) in ac microgrids. This strategy allows managing instantaneous active and reactive power without using a conventional inner-loop current ... -
Novel 3D bio-macromolecular bilinear descriptors for protein science: Predicting protein structural classes
(Academic Press, 2015)In the present study, we introduce novel 3D protein descriptors based on the bilinear algebraic form in the ℝn space on the coulombic matrix. For the calculation of these descriptors, macromolecular vectors belonging to ... -
Optimum search strategies or novel 3D molecular descriptors: Is there a stalemate?
(Bentham Science Publishers B.V., 2015)The present manuscript describes a novel 3D-QSAR alignment free method (QuBiLS-MIDAS Duplex) based on algebraic bilinear, quadratic and linear forms on the kth two-tuple spatial-(dis)similarity matrix. Generalization schemes ... -
Towards better BBB passage prediction using an extensive and curated data set
(Wiley-VCH Verlag, 2015)In the present report, the challenging task of drug delivery across the blood-brain barrier (BBB) is addressed via a computational approach. The BBB passage was modeled using classification and regression schemes on a novel ... -
Variational thermodynamics of relativistic thin disks
(Springer New York LLC, 2015)We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the ... -
