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 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 faster algorithm to compute the visibility map of a 1.5D terrain
(2014)
Text en actes de congrés
Accés obertGiven a 1.5D terrain, i.e., an x -monotone polygonal line in R 2 with n vertices, and 1 m n viewpoints placed on some of the terrain vertices, we study the problem of computing the parts of the terrain that are visible ... -
A finite element strategy coupling a gradient-enhanced damage model and cohesive cracks for quasi-brittle materials
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialA new combined strategy to describe failure of quasi-brittle materials is presented thus allowing the complete description of the process, from initiation of damage to crack propagation. For the early stages of the process, ... -
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 upper bound formulations in limit analysis
(John Wiley & Sons, 2012-08-24)
Article
Accés restringit per política de l'editorialIn this paper we study some recent formulations for the computation of upper bounds in limit analysis. We show that a previous formulation presented by the authors does not guarantee the strictness of the upper bound, ... -
A numerical technique for obtaining SEA coupling loss factors in double walls
(2012)
Text en actes de congrés
Accés obertDouble walls usually consist of two leaves of material connected by steel studs. Aside from improving the structural performance, studs create a vibration transmission path which connects the two leaves. There is interest ... -
