A case study for the assessment of a dynamic passenger ride sharing mobility service
(2017)
Text en actes de congrés
Accés restringit per política de l'editorialSustainable mobility is not merely a technological question. While automotive technology will be part of the solution, it will also be combined with a paradigm shift from car ownership to vehicle usage, which itself will ... -
A comparison of computational approaches for maximum likelihood estimation of the Dirichlet parameters on high-dimensional data
(Institut d'Estadística de Catalunya, 2015-06)
Article
Accés obertLikelihood estimates of the Dirichlet distribution parameters can be obtained only through numerical algorithms. Such algorithms can provide estimates outside the correct range for the parameters and/or can require a large ... -
A face-centred finite volume approach for coupled transport phenomena and fluid flow
(2024-01-01)
Article
Accés obertWe present a particular derivation of the face-centred finite volume (FCFV) method and study its performance in non-linear, coupled transport problems commonly encountered in geoscientific and geotechnical applications. ... -
A general procedures for deriving thin plate bending elements with one degree of feedom por node
(1993-04)
Report de recerca
Accés obert -
A general stabilized formulation for incompressible fluid flow using finite calculus and the finite element method
(2003-03)
Report de recerca
Accés obertWe present a general formulation for incompressible fluid flow analysis using the finite element method (FEM). The necessary stabilization for dealing with convective effects and the incompressibility condition are introduced ... -
A heuristic method for a congested capacitated transit assignment model with strategies
(2017-12)
Article
Accés obertThis paper addresses the problem of solving the congested transit assignment problem with strict capacities. The model under consideration is the extension made by Cominetti and Correa (2001), for which the only solution ... -
A likelihood ratio approach for identifying three-quarter siblings in genetic databases
(2021-01-15)
Article
Accés obertThe detection of family relationships in genetic databases is of interest in various scientific disciplines such as genetic epidemiology, population and conservation genetics, forensic science, and genealogical research. ... -
A low dimensional surrogate model for a fast estimation of strain in the thrombus during a thrombectomy procedure
(Elsevier, 2023-01-01)
Article
Accés restringit per política de l'editorialBackground Intra-arterial thrombectomy is the main treatment for acute ischemic stroke due to large vessel occlusions and can consist in mechanically removing the thrombus with a stent-retriever. A cause of failure of the ... -
A mathematical model coupling tumor growth and angiogenesis
(Public Library of Science (PLOS), 2016-02-18)
Article
Accés obertWe present a mathematical model for vascular tumor growth. We use phase fields to model cellular growth and reaction-diffusion equations for the dynamics of angiogenic factors and nutrients. The model naturally predicts ... -
A mathematical model of tumour angiogenesis: growth, regression and regrowth
(2017-01)
Article
Accés obertCancerous tumours have the ability to recruit new blood vessels through a process called angiogenesis. By stimulating vascular growth, tumours get connected to the circulatory system, receive nutrients and open a way to ... -
A network algorithm for the X chromosomal exact test for Hardy–Weinberg equilibrium with multiple alleles
(2021-07-01)
Article
Accés obertStatistical methodology for testing the Hardy-Weinberg equilibrium at X chromosomal variants has recently experienced considerable development. Up to a few years ago, testing X chromosomal variants for equilibrium was ... -
A non-intrusive proper generalized decomposition scheme with application in biomechanics
(John Wiley & Sons, 2017-09-07)
Article
Accés obertProper generalized decomposition (PGD) is often used for multiquery and fast-response simulations. It is a powerful tool alleviating the curse of dimensionality affecting multiparametric partial differential equations. ... -
A note on the likelihood and moments of the skew-normal distribution
(Institut d'Estadística de Catalunya, 2008)
Article
Accés obertIn this paper an alternative approach to the one in Henze (1986) is proposed for deriving the odd moments of the skew-normal distribution considered in Azzalini (1985). The approach is based on a Pascal type triangle, which ... -

A survey on pre-processing techniques: relevant issues in the context of environmental data mining
(IOS Press, 2016-12)
Article
Accés obertOne of the important issues related with all types of data analysis, either statistical data analysis, machine learning, data mining, data science or whatever form of data-driven modeling, is data quality. The more complex ... -
A text-mining approach to assess the failure condition of wind turbines using maintenance service history
(2019-05-23)
Article
Accés obertDetecting and determining which systems or subsystems of a wind turbine have more failures is essential to improve their design, which will reduce the costs of generating wind power. Two of the most critical failures, the ... -
A theoretical model of the endothelial cell morphology due to different waveforms
(2015-08)
Article
