Design considerations for primary control in multi-terminal VSC-HVDC grids
(2015-05-01)
Article
Accés obertMulti-terminal dc networks based on voltage source converters (VSC) are the latest trend in dc-systems; the interest in the area is being fueled by the increased feasibility of these systems for the large scale integration ... -
Estimación de la escorrentía superficial para el cálculo de la recarga a los acuíferos del macizo kárstico de los Ports de Beseit (Tarragona, España) combinando balance de agua en el suelo y análisis de hidrogramas de caudales
(2016-01-01)
Article
Accés obertPara la correcta estimación de la recarga por precipitación a los acuíferos tiene especial relevancia tener en cuenta la generación de escorrentía superficial. No considerarla en el cálculo de los recursos hídricos ... -
Experimental data and CFD performance for cloud dispersion analysis: The USP-UPC project
(2015-11-01)
Article
Accés obertForecasting the behaviour of a flammable or toxic cloud is a critical challenge in quantitative risk analysis. Recent literature shows that empirical and integral models are unable to model complex dispersion scenarios, ... -
Flexible batch process and plant design using mixed-logic dynamic optimization: single-product plants
(2014-11-05)
Article
Accés restringit per política de l'editorialBatch manufacturing plants require the frequent adaptation of production facilities to incorporate internal and external uncertainties. The introduction of flexibility in the design of general-purpose plants represents a ... -
Link between autumnal Arctic Sea ice and Northern Hemisphere winter forecast skill
(American Geophysical Union (AGU), 2020-02-28)
Article
Accés obertDynamical forecast systems have low to moderate skill in continental winter predictions in the extratropics. Here we assess the multimodel predictive skill over Northern Hemisphere high latitudes and midlatitudes using ... -
Robust state-feedback control of uncertain LPV systems : an LMI-based approach
(2014-05-01)
Article
Accés restringit per política de l'editorialIn this paper, the problem of designing an LPV state-feedback controller for uncertain LPV systems that can guarantee some desired bounds on the H-infinity and the H-2 performances and that satisfies some desired constraints ... -
Robust unknown input observer for state and fault estimation in discrete-time Takagi-Sugeno systems
(2016-01-01)
Article
Accés obertIn this paper, a robust unknown input observer (UIO) for the joint state and fault estimation in discrete-time Takagi-Sugeno (TS) systems is presented. The proposed robust UIO, by applying the H-infinity framework, leads ... -
Single-picture reconstruction and rendering of trees for plausible vegetation synthesis
(2016-06-01)
Article
Accés obertState-of-the-art approaches for tree reconstruction either put limiting constraints on the input side (requiring multiple photographs, a scanned point cloud or intensive user input) or provide a representation only suitable ... -
The recoverable robust facility location problem
(2015-09-01)
Article
Accés obertThis work deals with a facility location problem in which location and allocation (transportation) policy is defined in two stages such that a first-stage solution should be robust against the possible realizations (scenarios) ... -
Use of redundant data to reduce estimation errors in geochemical speciation
(2015-04)
Article
Accés obertSpeciation is the process of evaluating the concentrations of all the species in a chemical system from equilibrium conditions and measured data such as total concentrations of components, electrical conductivity, pH, redox ... -
Using mathematical knowledge management to support integrated decision-making in the enterprise
(Pergamon Press, 2014-07-04)
Article
Accés restringit per política de l'editorialThe basis of decision-making in the enterprise consists in formally representing the system and its subsystems in models which adequately capture those features which are necessary to reach consistent decisions. This work ... -
White dwarf evolutionary sequences for low-metallicity progenitors: The impact of third dredge-up
(2015-04-01)
Article
Accés obertContext. White dwarfs are nowadays routinely used as reliable cosmochronometers, allowing several stellar populations to be dated.; Aims. We present new white dwarf evolutionary sequences for low-metallicity progenitors. ...
