Simulating the tail of the interference in a Poisson network model
Full text linkInterference among simultaneous transmissions represents the main limitation factor for the capacity and connectivity of dense wireless networks. In this paper we provide efficient simulation laws for the tail of the interference in a simple wireless ad hoc network model. Particularly, we consider node locations distributed according to a Poisson point process and various classes of light-tailed fading distribution
Demographic and household composition of refugee and internally-displaced Ukraine populations: findings from an online survey
No full textAuthored by Brienna Perelli-Harris, Orsola Torrisi, Michael G Head and Ken Brackstone, this Migration Research Series paper highlights the household composition and characteristics of those displaced by the Russian Federation's invasion of Ukraine. The paper showcases the findings of a rapid online health needs survey disseminated via Facebook between April and July 2022. The survey discusses the findings from 10,180 respondents, making suggestions for policies that can mitigate some of the effects of the displacement crisis

Flora Sisti – Giovanni Torrisi – Università Carlo Bo – Urbino
Abstract (Italiano)
I nuovi mezzi di comunicazione offrono un enorme potenziale per i processi di innovazione sociale,
didattica e tecnologica del sistema universitario. Viviamo in una società liquida, dove l’informazione è
ubiqua, i servizi sono globali e le popolazioni si spostano costantemente. In questo contesto, anche il ruolo
dell’università cambia ed emergono nuove forme di apprendimento.
L’ateneo di Urbino mette a sistema una tradizione già consolidata di servizi didattici grazie all’istituzione del
CISDEL che fornirà un utile caso di studio nel presente contributo.
Il CISDEL promuove un modello didattico istituzionalizzato che coniuga contenuti e prassi innovative con la
dimensione tecnologica realizzata attraverso tre diverse piattaforme digitali: elearning.uniurb.it, dedicata ai
servizi a distanza; blended.uniurb.it, che aggiunge alla tradizionale didattica in aula nuovi strumenti e
modalità di apprendimento ed education.uniurb.it, riservata all’offerta di formazione per il life-longlearning.
The Puzzle of Didactic Innovation at the University of Urbino: The CISDEL Experience (The Integrated
Centre for University Didactic Services and E-Learning)
Abstract (English)
New means of communication offer enormous potential for processes of social, didactic and technological
innovation within the university system. We live in a liquid society in which information is ubiquitous,
services are global and populations move constantly. In this context, where new learning forms are
emerging, the role of the university must change.
The University of Urbino improves organizationally its consolidated tradition of didactic services to students
and teachers thanks to the institutionalization of CISDEL, which becomes an interesting case-study for the
present contribution.
CISDEL promotes an innovative didactic model which combines new contents and teaching/learning
strategies with ICT through three different online platforms: elearning.uniurb.it, dedicated to distance
learning; blended.uniurb.it, which adds new tools and learning modes to traditional didactics; and
education.uniurb.it, which offers high education life-long learning courses

Introduzione
No full textQuesto volume raccoglie gli atti del convegno “Oltre Basilea 2: nuove sfide competitive per le PMI” organizzato dalla Facoltà di Economia – Sede di Rimini dell’Università di Bologna in collaborazione con la Fondazione CARIM e la CCIAA di Rimini il 21 Settembre 2007.
Alla luce della crisi finanziaria ed economica che ha colpito le principali economie mondiali, gli accordi di Basilea 2, basati su alcuni pilastri relativi ai meccanismi di copertura dai principali rischi finanziari (credito, mercato ed operativo), tornano ad essere oggetto di dibattito.
L’adozione di approcci di valutazione del rischio basati sui rating interni, come quelli suggeriti da Basilea 2, se da un lato rende più efficiente il monitoraggio del rischio dei singoli clienti (valutati sulla base di criteri quantitativi e qualitativi), dall’altro può generare una maggiore pro-ciclicità. Il peggioramento della qualità media delle imprese dovuto alla congiuntura sfavorevole comporta un abbassamento del rating medio e quindi un aumento nel capitale che le banche sono tenute ad accantonare a copertura del rischio di credito. Un maggiore accantonamento a riserva, a sua volta, comporta una riduzione dell’offerta di credito e quindi amplifica le difficoltà delle imprese debitrici.
L’attuale crisi economico-finanziaria mette in evidenza la necessità di una riforma di Basilea 2 ma non riduce il valore di questo nuovo sistema di regole come stimolo ad una maggiore trasparenza e rigore nella contabilità e nella gestione finanziaria rispetto al passato. Nonostante i difetti, che certamente vanno corretti, Basilea 2 ha il pregio di richiedere alle imprese grande disciplina e uno sforzo significativo per segnalare all’esterno l’effettiva capacità di fare fronte in ogni momento agli impegni finanziari derivanti dalla propria gestione industriale. In questa prospettiva i rapporti tra banca e impresa tendono ad assumere una minore discrezionalità rispetto al passato, con evidenti benefici per le imprese di “buona” qualità
Shockwave and spallation in silver and other materials by sub-ns laser pulse at 10^16 W/cm^2 intensity
Full text linkThe laser spallation effect due to intense shockwaves caused by a brief and intense laser pulse irradiating a target surface, 2 mm thick, has been investigated for silver and other materials. For 300 ps IR laser pulse, at intensities of the order of 10(16) W/cm(2), the shockwave may produce deformations of the back-face in ductile materials, such as Ag, Cu and Al. In heavy materials with high tensile strength, such as Ta, the shockwave produces cracks in the bottom of the laser crater but not deformation in the back-face, while in brittle materials, such as monocrystalline Ge, it produces only superficial cracks and flaking, but not deformation and spallation of the back-face. In thick polymeric materials, such as high-density polyethylene, the ablated crater shape is well defined and the shockwave is strongly damped, and no deformation has been observed in the back-face. The laser ablation yield and the ion acceleration in the backward direction have been measured by mass lost and time-of-flight measurements. SEM microscopy of the different irradiated targets, showing details of the crater size, edges, flaking and deformation in the back-face, useful for a discussion on the shockwave propagation and shock pressure calculation, is presented
neutron source controlled by high‐intensity pulsed laser generating plasma
No full textA laptop neutron source suited for the most demanding field or laboratory applications is presented. It is based on laser ablation of CD2 primary targets, plasma acceleration of the D+ ions, and their irradiation of secondary CD2 targets. The deuterium–deuterium (D-D) fusion reaction is induced in the secondary target, according to the values of fusion cross-section versus deuteron energy, which show a significant probability also at relatively low ion energies. The experiments were completed in the PALS laboratory, Prague, detecting monoenergetic neutrons at 2.45 MeV with an emission flux of about 109 neutrons per laser shot. Other experiments demonstrating the possibility to induce D-D events were performed at IPPLM, Warsaw, and at INFN-LNS, Catania, where the deuterons were accelerated at about 4 MeV and 50 keV, respectively. In the last case, a low laser intensity and a post-ion acceleration system were employed. A special interaction chamber, under vacuum, is proposed to develop a new source of monochromatic neutrons or thermalized distribution of neutrons
laser ablation in vacuum and in water to deposit thin films or to generate nanoparticles in solution
No full textAn ns Nd:YAG pulsed laser was used to deposit thin films in a vacuum and to generate nanoparticles in the water of Ni, Ti, and NiTi alloys. Laser ablation was measured in terms of removing mass per laser pulse. The laser-generated plasma in vacuum was characterized in terms of temperature and energy of emitted particles. The ablation in water produces nanoparticles with dimensions of the order of 25 nm and solutions with concentrations of the order of some mg/ml. The NiTi alloy stoichiometry is well reported in the deposited thin film and in the composition of the produced nanoparticles
