Het diffusion anisotropy in dendritic growth: phase field simulations and experiments in liquid crystals
(Elsevier, 1998-10-15)
Article
Accés restringit per política de l'editorialAn anisotropic heat diffusion coefficient is introduced in order to study some interfacial growth phenomena. This anisotropy has been incorporated in a phase field model which has been studied numerically to reproduce some ... -
La combinatoria poliédrica y el problema del agente viajero: aplicación al caso de ciento tres ciudades españolas
(Universitat Politècnica de Barcelona. Centre de Càlcul, 1985-09)
Article
Accés obertEl trabajo resume los resultados de la aplicación de la Combinatoria Poliédrica al Problema del Viajante (TSP): definición del poliedro, dimensión, desigualdades válidas, facetas. Estos resultados se aplican al caso concreto ... -
Pattern formation during mesophase growth in a homologous series
(American Physical Society, 1996-08-01)
Article
Accés restringit per política de l'editorialRemarkable differences in the shape of the nematic-smectic-B interface in a quasi-two-dimensional geometry have been experimentally observed in three liquid crystals of very similar molecular structure, i.e., neighboring ... -
Phase field simulations and experiments of faceted growth in liquid crystals
(Elsevier Science, 1996-12-01)
Article
Accés restringit per política de l'editorialWe present numerical simulations directed at the description of smectic-B germs growing into the supercooled nematic phase for two different liquid crystalline substances. The simulations are done by means of a phase-field ... -
The generalized arc routing problem
(Springer, 2017-10)
Article
Accés obertThis paper focuses on the generalized arc routing problem. This problem is stated on an undirected graph in which some clusters are defined as pairwise-disjoint connected subgraphs, and a route is sought that traverses at ... -
Validation of the JPL multipath fading model using measurements from the lunar reconnaissance orbiter
(Universitat Politècnica de Catalunya, 2022-07)
Treball Final de Grau
Accés restringit per decisió de l'autorNASA JPL ha dissenyat un nou model numèric determinístic de propagació per carac- teritzar el canal entre un transmissor a la Lluna i un receptor a la Terra. En concret, el transmissor pot ser un rover o una estació base ...
