An approach to evaporating stars and black holes
(2011-09-01)
Article
Open AccessMany models in which the object under study loses all its mass have appeared in the literature. No doubt, the most eminent examples are the models for evaporating black holes and for evaporating stars. Here we describe ... -
El proyecto arquitectónico a la luz del “paradigma indicial”
(Centre de Política del Sòl i Valoracions - Universitat Politècnica de Catalunya, 2017-06)
Article
Open AccessEste trabajo pretende mostrar un modelo sobre cómo se generan y organizan los conocimientos propios de disciplinas que, aun usando la ciencia y la tecnología como herramientas, se sitúan, por su esencia, más allá de éstas. ... -

Física aplicada al càlcul estructural arquitectònic
(Universitat Politècnica de Catalunya. Iniciativa Digital Politècnica, 2017)
Book
Open AccessEn aquest llibre s’ofereix una introducció moderna al càlcul estructural. Es pretén que les noves generacions d’arquitectes coneguin des dels primers cursos, d’una banda, els fonaments de la ciència que són aplicables a ... -
La rellevància de les matemàtiques i l'estadística en el món actual : taula rodona
(2003-11-01)
Audiovisual
Open AccessDins el marc de la 8a Setmana de la Ciència es va celebrar aquesta taula rodona on es debat sobre la presència i la necessitat dels mètodes que proporcionen la matemàtica, l'estadística i la investigació operativa en la ... -
Local behaviour of evaporating stars and black holes around the total evaporation event

Maxwell equations in the Debye potential formalism
(1985-02-01)
Article
Open AccessThe authors propose a method for computing the electromagnetic test-field created by a given distribution of charges and currents using the Debye potential formalism in curved space-times. This framework has been applied ... -
On how energy conservation might prevent black hole explosions and violations of the third law
(2013-11-12)
Article
Open AccessWe claim that imposing energy conservation to the emission of Hawking radiation and to the modeling of black hole (BH) evaporation might prevent BH explosions as well as violations of the third law of BH thermodynamics. ... -
On regular rotating black holes
(2017-01-01)
Article
Open AccessDifferent proposals for regular rotating black hole spacetimes have appeared recently in the literature. However, a rigorous analysis and proof of the regularity of this kind of spacetimes is still lacking. In this note ... -
On the causal characterization of singularities in spherically symmetric spacetimes
(2011-10-14)
Article

On the invariant causal characterization of singularities in spherically symmetric spacetimes
(2012-04-18)
Article
Open AccessThe causal character of singularities is often studied in relation to the existence of naked singularities and the subsequent possible violation of the cosmic censorship conjecture. Generally, one constructs a model in the ... -
On the quantum corrected gravitational collapse
(Elsevier, 2015-06-09)
Article
Open AccessBased on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars. As the modeled star collapses a closed apparent ... -
Relación entre la nota de acceso a la universidad y el rendimiento académico en los estudios de Arquitectura: el caso del Plan 94 de la Escuela de Arquitectura de Barcelona
(Centre de Politica de Sol i Valoracions, CPSV / Universitat Politècnica de Catalunya, UPC, 2021-10-31)
Article
Open AccessEls estudis d'Arquitectura tenen com a espina dorsal la metodologia activa de l'aprenentatge basat en projectes (ABP). "Aprendre fent projectes" entronca amb la metodologia que s'està implementant als entorns d'aprenentatge ... -
Singularity free gravitational collapse in an effective dynamical quantum spacetime
(Elsevier, 2014-05-05)
Article
Open AccessWe model the gravitational collapse of heavy massive shells including its main quantum corrections. Among these corrections, quantum improvements coming from Quantum Einstein Gravity are taken into account, which provides ... -
The mechanism why colliders could create quasi-stable black holes
(2013-09-09)
Article
Open AccessIt has been postulated that black holes could be created in particle collisions within the range of the available energies for nowadays colliders (LHC). In this paper we analyze the evaporation of a type of black holes ...
