A local stability condition for dc grids with constant power loads
(2017-07-01)
Article
Accés obertCurrently, there are an increasing number of power electronics converters in electrical grids, performing the most diverse tasks, but most of them, work as constant power loads (CPLs). This work presents a sufficient ... -
A localized mapped damage model for orthotropic materials
(2014-05-08)
Article
Accés restringit per política de l'editorialThis paper presents an implicit orthotropic model based on the Continuum Damage Mechanics isotropic models. A mapping relationship is established between the behaviour of the anisotropic material and that of an isotropic ... -
A locally adaptive kernel regression method for facies delineation
(2015-12-01)
Article
Accés obert -
A locally extended finite element method for the simulation of multi-fluid flows using the Particle Level Set method
(2015-09)
Article
Accés obertThe simulation of immiscible two-phase flows on Eulerian meshes requires the use of special techniques to guarantee a sharp definition of the evolving fluid interface. This work describes the combination of two distinct ... -
A Location-Routing Model for a Two-Echelon System of Urban
(Universitat Politècnica de Catalunya, 2013-11)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThe freight distribution system of many cities suffering from congestion is based on the use of a single echelon of consolidation facilities that are located in the city outskirts. In this thesis, the introduction of a ... -
A locking-free face-centred finite volume (FCFV) method for linear elastostatics
(2019-02-01)
Article
Accés obertA face-centred finite volume (FCFV) method is proposed for linear elastostatic problems. The FCFV is a mixed hybrid formulation, featuring a system of first-order equations, that defines the unknowns on the faces (edges ... -
A log-ratio biplot approach for exploring genetic relatedness based on identity by state
(2019-04-24)
Article
Accés obertThe detection of cryptic relatedness in large population-based cohorts is of great importance in genome research. The usual approach for detecting closely related individuals is to plot allele sharing statistics, based on ... -
A logic approach for exceptions and anomalies in association rules
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article
Accés obertAssociation rules have been used for obtaining information hidden in a database. Recent researches have pointed out that simple associations are insu cient for representing the diverse kinds of knowledge collected in ... -
A logic of graph conditions extended with paths
(2016)
Text en actes de congrés
Accés obertIn this paper we tackle the problem of extending the logic of nested graph conditions with paths. This means, for instance, that we may state properties about the existence of paths between some given nodes. As a main ... -

A logic programming approach to parsing and production in fluid construction grammar
(Springer, 2012)
Capítol de llibre
Accés restringit per política de l'editorialThis paper presents a Logic Programming approach to parsing and production in Fluid Construction Grammar (FCG). It builds on previous work on the formalisation of FCG in terms of First Order Logic (FOL) concepts, more ... -
A logic-based environmental decision support system for the management of horizontal subsurface constructed wetlands
(2012-04-02)
Article
Accés restringit per política de l'editorialThe use of Horizontal Subsurface Constructed Wetlands (HSCWs) for treating wastewaters in small communities has increased in the last years due to HSCW’s ecological singularities. Unfortunately, the same singularities ... -
A logic-based incremental approach to graph repair featuring delta preservation
(Springer Nature, 2021-07-07)
Article
Accés obertWe introduce a logic-based incremental approach to graph repair, generating a sound and complete (upon termination) overview of least-changing graph repairs from which a user may select a graph repair based on non-formalized ... -
A logistic approximation to the cumulative normal distribution
(School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2009-06)
Article
Accés obertThis paper develops a logistic approximation to the cumulative normal distribution. Although the literature contains a vast collection of approximate functions for the normal distribution, they are very complicated, not ... -
A logistic queue model for network traffic modeling and simulation
(Universitat Politècnica de Catalunya, 2017-07)
Projecte Final de Màster Oficial
Accés obertIn this work we present a continuous queuing model called the logistic queue model. We show that in terms of queue size and outflow prediction, our model is as precise as a discrete event simulator with the additional ... -

(2006-08-31)
Article
Accés obertA long Saharan dust event affected the western Mediterranean in the period 12– 28 June 2002. Dust was present mainly between 1- and 5-km height affecting most parts of the Iberian Peninsula and reaching western/central ... -
