Article
Accés obertAs well as in other natural processes, it has been frequently observed that the phenomenon arising from the rainfall generation process presents fractal self-similarity of statistical type, and thus, rainfall series generally ... -
A single-center, randomized, double-blind, placebo-controlled study of interferon beta-1b on primary progressive and transitional multiple sclerosis
(2009-10)
Article
Accés restringit per política de l'editorialInflammation and neurodegeneration may have differential impacts on disease evolution in the different forms of multiple sclerosis. However, a beneficial effect of immunomodulatory drugs should not be ruled out in primary ... -
A single-residue substitution inhibits fibrillization of Ala-based pentapeptides. A spectroscopic and molecular dynamics investigation
(2014-01-01)
Article
Accés obertThe aggregation properties of two Ala-based pentapeptides were investigated by spectroscopic techniques and molecular dynamics (MD) simulations. The two peptides, both functionalized at the N-terminus with a pyrenyl group, ... -

A singular initial value problem to construct density-equalizing maps
(2011-12)
Article
Accés restringit per política de l'editorialThe diffusion-based algorithm to produce density-equalizing maps interprets diffusion as an advection process. This algorithm uses the dynamics of a flow that is defined by an initial value problem that turns out to be ... -

Accés obertThe diffusion-based algorithm to produce density-equalizing maps interprets diffusion as an advection process. This algorithm uses the dynamics of a flow that is defined by an initial value problem that turns out to be ... -
A singularity-free path planner for closed-chain manipulators
(IEEE, 2012)
Text en actes de congrés
Accés obertThis paper provides an algorithm for computing singularity-free paths on non-redundant closed-chain manipulators. Given two non-singular configurations of the manipulator, the method attempts to connect them through a ... -
A singularity-robust LQR controller for parallel robots
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertParallel robots exhibit the so-called forward singularities, which complicate substantially the planning and control of their motions. Often, such complications are circumvented by restricting the motions to singularity-free ... -
A situational approach for the definition and tailoring of a data-driven software evolution method
(Springer, 2018)
Text en actes de congrés
Accés obertSuccessful software evolution heavily depends on the selection of the right features to be included in the next release. Such selection is difficult, and companies often report bad experiences about user acceptance. To ... -

Report de recerca
Accés obertWe present a C++ implementation of a skeleton for Tabu Search method. Tabu Search method is a well-known meta-heuristic that has proved successful for sub-optimally solving hard combinatorial optimization problems. Recently ... -
A skewness-aware matrix factorization approach for mesh-structured cloud services
(2019-08)
Article
Accés obertOnline cloud services need to fulfill clients' requests scalably and fast. State-of-the-art cloud services are increasingly deployed as a distributed service mesh. Service to service communication is frequent in the mesh. ... -
A sliding mode control for a wound rotor synchronous generator with an isolated RL load
(IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Comunicació de congrés
Accés obertIn this paper a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive ... -
A sliding mode controlled three wheeled narrow vehicle
(2013)
Article
Accés restringit per política de l'editorialThis paper presents a sliding mode controller for a narrow tilting three-wheeled vehicle. The vehicle is modelled as a dynamic eighteen-order system with two inputs and two outputs, however, a simple third-order model of ... -
