Architetture del made in Italy, da Adriano Olivetti alla Green Economy”. Nel padiglione sono raccontati alcuni esempi di “architettura sensibile” come approccio possibile durante la crisi e come esempio di intervento per il futuro. Il progetto di recupero della storica borgata di Paraloup Paraloup opera del prof.

VET, an Epidemic Transport Protocol for Retrieving Multimedia Contents in Vehicular Networks
No full textDesign and evaluation of a collaborative system for content diffusion and retrieval in vehicular networks
No full textThe availability of infotainment contents to be accessed while driving constitutes an added value to both drivers and passengers, improving their travel experience. These contents can be already on-board, diffused through broadcast networks (e.g., FM radio) or delivered on demand by servers as data streams. Vehicular ad-hoc networks (VANET) allow envisaging a new way to access contents based on epidemic data dissemination, tearing down the costs for both the user and the content publisher, and increasing system scalability. In this paper, we present the design and the evaluation of a collaborative system for content diffusion and retrieval among traveling vehicles. This system relies on multicast epidemic dissemination of messages and exploits vehicles mobility and their local storage capabilities. In order to assess its performance, several simulations have been carried out, using real-world maps and realistic mobility models, and varying intrinsic system parameters. Experimental results suggest that the system is feasible, produces reliable results, almost independent of the mobility scenario, and can be used as a peer-to-peer download accelerator for improving client-server acces
Epidemic information diffusion in realistic vehicular network mobility scenarios
No full textEpidemic or gossip-based algorithms have been proposed for data dissemination in vehicular networks. Due to the unfeasibility of deploying large size vehicular networks, the performance evaluation of these algorithms is usually based on simulations. However, most literature works present experimental results based on hyper-simplified and non-realistic mobility scenarios or do not adequately describe the simulation setup. In this paper, we investigate the impact that road-network and vehicle density have on the performance of epidemic dissemination and the correlation between these factors and other simulation parameters, such as percentage of equipped vehicles, message expiration time, scheduling algorithm for data retransmission and number of circulating messages. We argue that, given the high sensitivity of this kind of approach to mobility scenarios, it would be useful to define a set of them to be used as a reference for evaluating different systems. Furthermore, from our simulations, we can state that, although epidemic diffusion does not guarantee data distribution to all network nodes, its simplicity and lack of infrastructure make it suitable for distributing real-time traffic or viability data in most mobility scenarios

Le «buone letture». 2. Giovanni Casati
No full textIl saggio è costituito da due parti, la prima delle quali, dedicata alla fondazione della Federazione italiana delle biblioteche circolanti cattoliche, è stata pubblicata nel precedente numero dei «Nuovi Annali», XXVII (2013), pp. 137-163. In questa seconda parte viene delineata la figura intellettuale di Giovanni Casati, che diresse la «Rivista di letture» dal 1912 al 1944, trasformando il periodico della Federazione in una rivista impegnata nella divulgazione della cultura cattolica. A questo impegno militante Casati fece corrispondere un intenso programma editoriale, che trovò espressione nella pubblicazione di saggi letterari, di manuali e opere repertoriali.The study consists of two parts; the first is dedicated to the history of the Federazione italiana delle biblioteche circolanti cattoliche since its foundation (1904) up to 1912 and was published in the previous volume of the «Nuovi Annali », XXVII (2013), pp. 137-163. In this second part, the author outlines the intellectual figure of Giovanni Casati, who directed the «Rivista di letture» from 1912 to 1944, transforming the magazine of the Federation in a journal engaged in the spreading of Catholic culture. To this militant engagement Casati matched an intense publishing program, which found its expression in the publication of literary essays, manuals and reference works
Exploring the values of writing collaboratively through a digital storytelling platform: a mixed-methods analysis of users'�� participation, perspectives and practices
No full textDigital technologies allow teachers and students to experience new pedagogical approaches leveraging on interactivity and collaboration. Among the available techniques, digital storytelling (DST) has been usually regarded as an activity that can both enrich the teaching practices and foster students' active behaviour. This paper aims at analysing to what extent a DST platform proposing the collaborative writing of a fictional story and leveraging on an active learning technique such as role-play can affect a variety of dimensions, namely students' performance, commitment, creativity and social skills. Combining the analysis of the data-log automatically collected by the system with the evaluations given by teachers before and after the activity, this article shows that the use of a DST tool in the teaching practice can have positive effects on students, including the ones that usually manifest moderate scores for the previously mentioned dimensions. Additionally, semi-structured interviews and direct observations provide an insight on how the benefits stemming from the use of a DST tool in the classroom can especially lie on the collaborative process that is activated
