Report de recerca
Accés obertIn this report we present a list of problems that originated in bionformatics. Our aim is to collect information on such problems that have been analyzed from the point of view of Parameterized Complexity. For every problem ... -
A literature review of design of criteria for supplier selection
(OmniaScience, 2018-12)
Article
Accés obertPurpose: This paper proposes a new model for further research on how to select criteria in supplier selection, through a literature review and analysis of the advantages and disadvantages of previously used methods. D ... -
A literature review on information systems support for the cooperation of firms within networks
(Universitat Politècnica de Catalunya, 2012)
Projecte/Treball Final de Carrera
Accés restringit per decisió de l'autorNowadays, any company wants to gain a clear competitive advantage in the market. In order to reach this goal it can be important to participate in networks, especially in the case of small and medium enterprises (SMEs). ... -
A literature review on learned helplessness in school environments
(Universitat Politècnica de Catalunya, 2017-06-22)
Projecte Final de Màster Oficial
Accés obertLearned helplessness is a form of learning which develops when the subject perceives a loss of control in inescapable situations. This can lead to the development of cognitive and social deficits. Main research on this ... -
A literature review on thermal comfort performance of parametric façades
(Elsevier, 2022-10)
Article
Accés obertThermal performance is a major part of the building envelope and is getting more attention globally. Nowadays, parametric design methods are used in building envelope design, such as facade design, for optimization of ... -

A load balancing method for parallel genetic CFD optimizations
(2015)
Text en actes de congrés
Accés restringit per política de l'editorialCFD optimizations are characterized by long and highly variable objective function evaluation times. The aim of this study is to improve the parallel performance using a new load balancing master-worker parallelization ... -
A local algorithm for the computation of image velocity via constructive interference of global Fourier components
(2011)
Article
Accés obertA novel Fourier-based technique for local motion detection from image sequences is proposed. In this method, the instantaneous velocities of local image points are inferred directly from the global 3D Fourier components ... -
A local constitutive model for the discrete element method: application to geomaterials and concrete
(Springer, 2015-06)
Article
Accés obertThis paper presents a local constitutive model for modelling the linear and non linear behavior of soft and hard cohesive materials with the discrete element method (DEM). We present the results obtained in the analysis ... -
A local multiple proper generalized decomposition based on the partition of unity
(John Wiley & sons, 2019-10-12)
Article
Accés obertIt is well known that model order reduction techniques that project the solution of the problem at hand onto alow-dimensional subspace present difficulties when this solution lies on a non-linear manifold. To overcomethese ... -
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 ... -

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 ... -
