Path integral solution by fractional calculus
2008
In this paper, the Path Integral solution is developed in terms of complex moments. The method is applied to nonlinear systems excited by normal white noise. Crucial point of the proposed procedure is the representation of the probability density of a random variable in terms of complex moments, recently proposed by the first two authors. Advantage of this procedure is that complex moments do not exhibit hierarchy. Extension of the proposed method to the study of multi degree of freedom systems is also discussed.
Digital Cultural Heritage

Most contemporary thinkers agree that we are going through a time of historical change, building adifferent concept and model of social interrelation. Our ways of life and work have changed, as havethe ways in which we communicate and relate to each other.
SIGIC-UV: Sistema Inform�tico de Garant�a Interna de Calidad para los centros y titulaciones de la
2015
Arran de la posada en marxa de l’espai europeu d’educacio superior, les universitats espanyoles han dissenyat sistemes de garantia interna de qualitat per als seus centres i les seues titulacions. Aquest article presenta en detall el Sistema Informatic de Garantia Interna de Qualitat de la Universitat de Valencia (SIGIQ-UV), una eina informatica de codi obert que integra tecnologies de gestio de processos de negoci amb tecnologies de repositori documental per al seguiment dels procediments de qualitat i l’emmagatzematge de les evidencies documentals resultants de la seua execucio. L’aproximacio modular amb que ha estat desenvolupat garanteix la flexibilitat del sistema, l’estat d’implantaci…
Actitudes de docentes y discentes ante la otra: la madre universitaria
2019
INTRODUCCIO. Aquesta investigacio intenta descobrir les experiencies de les persones que son mares i al mateix temps alumnes en l’educacio superior, que miren d’equilibrar les moltes responsabilitats associades amb els seus papers de mare, membre de la familia, amiga i estudiant universitaria. S’aborda la problematica de la conciliacio estudiantil familiar des d’una perspectiva de genere. METODE. En aquest estudi, a partir d’una metodologia feminista qualitativa basada en narratives mitjancant entrevistes semiestructurades, s’analitzen les creences i actituds d’un total de tretze estudiants universitaries. RESULTATS. A traves del pensament narratiu, emprem les seves histories com un mitja p…
Docente y futuros maestros aprendiendo a ver la influencia de la cultura visual televisiva en los d
2015
Aquest estudi aborda la tematica del desenvolupament del dibuix infantil des d'una perspectiva actualitzada que aprofundeix en els llocs dels que poden procedir nous recursos expressius i comunicatius que els nens, aproximadament a partir dels 7 anys, incorporen progressivament en les seves creacions. El principal objectiu d'aquesta investigacio consisteix en detectar les influencies de la Cultura Visual televisiva en els dibuixos infantils. La investigacio es desenvolupa en un proces compartit amb alumnat de l'assignatura de "Didactica de l'Educacio Plastica i Visual de l'Educacio Primaria". Els influxos, que alteren un suposat curs "natural" en l'evolucio del dibuix infantil, s'evidencien…
Maximizing phonon thermal conductance for ballistic membranes
2007
At low temperatures, phonon scattering can become so weak that phonon transport becomes ballistic. We calculate the ballistic phonon conductance G for membranes using elasticity theory, considering the transition from three to two dimensions. We discuss the temperature and thickness dependence and especially concentrate on the issue of material parameters. For all membrane thicknesses, the best conductors have, counter-intuitively, the lowest speed of sound.
Influence of impurity scattering on Drude response in heavy-fermion UPd2Al3
2010
The frequency-dependent conductivity of heavy-fermion metals can often be described within the picture of the Drude response: the transport relaxation rate is the only relevant frequency scale and, furthermore, reduced by orders of magnitude compared to normal metals. While the relaxation-time enhancement corresponds to the effective-mass enhancement in these materials, i.e. a fundamental material characteristic, the absolute value of the relaxation time depends on the details of the relevant scattering processes. Here we discuss the influence of impurity scattering on the Drude response of the heavy fermions in UPd2Al3 by comparing different thin film samples.
Coping Styles and Social Support in Emergency Workers: Family as a Resource
2015
The nature of the job of people working in emergency situations is such that they may experience high levels of stress. With the term ‘emergency’, we refer to macroscopic events (floods, earthquakes) but also to micro-emergencies, that are more frequent events like accidents and acts of violence. Therefore, the aim of this approach is to help to prevent, or to overcome, the psychic phenomenon that occurs in the victims after a traumatic event that is unexpected and upsetting. In disaster and emergency scenarios, empirical data shows that an effective intervention is able to activate pro-social behaviours, based on social relations and norms; but for emergency workers there are several dange…
Distributed Data Collection for the ATLAS EventIndex
2015
The ATLAS EventIndex contains records of all events processed by ATLAS, in all processing stages. These records include the references to the files containing each event (the GUID of the file) and the internal “pointer” to each event in the file. This information is collected by all jobs that run at Tier-0 or on the Grid and process ATLAS events. Each job produces a snippet of information for each permanent output file. This information is packed and transferred to a central broker at CERN using an ActiveMQ messaging system, and then is unpacked, sorted and reformatted in order to be stored and catalogued into a central Hadoop server. This contribution describes in detail the Producer/Consu…
ATLAS operations in the GridKa T1/T2 Cloud
2011
The ATLAS GridKa cloud consists of the GridKa Tier1 centre and 12 Tier2 sites from five countries associated to it. Over the last years a well defined and tested operation model evolved. Several core cloud services need to be operated and closely monitored: distributed data management, involving data replication, deletion and consistency checks; support for ATLAS production activities, which includes Monte Carlo simulation, reprocessing and pilot factory operation; continuous checks of data availability and performance for user analysis; software installation and database setup. Of crucial importance is good communication between sites, operations team and ATLAS as well as efficient cloud l…
