Application of reverse engineering concepts to compressed air tank
(Universitat Politècnica de Catalunya, 2010-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThis study, application of reverse engineering concepts to a compressed air tank, leads us to calculate tank shell in static and fatigue, by using of formulas and software. Furthermore, unsatisfying results from basics ... -
Desarrollo de una herramienta numérica de problema inverso para la estimación óptima de parámetros de entrada en Kratos Multiphysics
(Universitat Politècnica de Catalunya, 2023-06-27)
Projecte Final de Màster Oficial
Accés obertEn problemes d'enginyeria, sovint és necessari calibrar els paràmetres d'entrada per poder reproduir els resultats experimentals de referència. Tot i que el procés de càlcul sigui correcte, si els paràmetres no estan ... -
Dirichlet-to-Robin matrix on networks
(2014)
Article
Accés obertIn this work, we de ne the Dirichlet{to{Robin matrix associated with a Schr odinger type matrix on general networks, and we prove that it satis es the alternating property which is essential to characterize those matrices ... -
On the asymptotic wavenumber of spiral waves in lambda - omega systems
(2016-01-01)
Article
Accés obertIn this paper we consider spiral wave solutions of a general class of $\lambda -\omega $ systems with a small twist parameter q and we prove that the asymptotic wavenumber of the spirals is a ${{\mathcal{C}}^{\infty}}$ ... -
Recovering the conductances on grids
(2014)
Article
Accés restringit per política de l'editorialIn this work, we present an algorithm to the recovery of the conductance of a 2– dimensional grid. The algorithm is based in the solution of some overdetermined partial boundary value problems defined on the grid. -
Recovering the conductances on grids: A theoretical justification
(2016)
Article
Accés obertIn this work, we present an overview of the work developed by the authors in the context of inverse problems on nite networks. This study performs an extension of the pioneer studies by E.B. Curtis and J.A. Morrow, ... -
Redes estrella con la M-propiedad
(Editorial Universidad de Almería, 2015)
Text en actes de congrés
Accés obertEn este trabajo hacemos una aportación al problema inverso de M –matrices irreducibles, simétricas y singulares, que consiste en determinar c uándo su inversa de grupo es también una M –matriz. Mostramos primero que las ... -
Reflector design from radiance distributions
(Institute for Applied Mathematics and Information Technology, 2004-12)
Article
Accés restringit per política de l'editorialThis paper proposes a technique for the design of reflector shapes from prescribed optical properties (far field radiance distribution) and geometrical constraints, which is of high importance in the field of Lighting ... -
Some inverse problems
(2011-07-06)
Report de recerca
Accés restringit per política de l'editorialThe Darboux theory of integrability for planar polynomial di®erential equations is a classical ¯eld, with connections to Lie symmetries, di®erential algebra and other areas of mathematics. In the present paper we introduce ... -
Topology of Cayley graphs applied to inverse additive problems
(Iniciativa Digital Politècnica, 2011)
Text en actes de congrés
Accés obertWe present the basic isopermetric structure theory, obtaining some new simplified proofs. Let 1 ≤ r ≤ k be integers. As an application, we obtain simple descriptions for the subsets S of an abelian group with |kS| ≤ ...
