Decadal climate prediction with a refined anomaly initialisation approach
(Springer International Publishing, 2016-06-04)
Article
Accés obertIn decadal prediction, the objective is to exploit both the sources of predictability from the external radiative forcings and from the internal variability to provide the best possible climate information for the next ... -
DECADE: Distributed Emergent Cooperation through ADaptive Evolution in mobile ad hoc networks
(Elsevier, 2012-09)
Article
Accés restringit per política de l'editorialThe scarce resources of a mobile ad hoc network (MANET) should not be wasted attending selfish nodes (those nodes that use resources from other nodes to send their own packets, without offering their own resources to forward ... -

(2022-12-12)
Article
Accés obertCO2 conversion to added value products using green processes in terms of source of energy, energy consumption, and/or management of raw materials obtained from waste materials are very attractive approaches for a modern ... -
Decarbonization Pathways for the German Chemical and Steel Industry
(Universitat Politècnica de Catalunya, 2020-11-20)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorCurrently Germany is failing to reach its set emission targets. To achieve the envisioned carbon neutrality until 2050 fundamental changes will have to be implemented in all productive and non-productive sectors in the ... -
Decay estimate of the viscoelastic plate with type II heat conduction in the whole space
(Elsevier, 2024-01)
Article
Accés restringit per política de l'editorialThis paper is concerning the problem determined by a viscoelastic plate when the heat is determined by the type II Green–Naghdi theory. Meanwhile the usual modeling is the combination of a conservative equation for the ... -
