Three-dimensional matching based resource provisioning for the design of low-latency heterogeneous IoT networks

2019

Internet-of-Things (IoT) is a networking architecture where promising, intelligent services are designed via leveraging information from multiple heterogeneous sources of data within the network. However, the availability of such information in a timely manner requires processing and communication of raw data collected from these sources. Therefore, the economic feasibility of IoT-enabled networks relies on the efficient allocation of both computational and communication resources within the network. Since fog computing and 5G cellular networks approach this problem independently, there is a need for joint resource-provisioning of both communication and computational resources in the networ…

Sogni e visioni nel mondo antico

2007

Recensione a: Valafrido Strabone, La visione di Vetti. Il primo viaggio poetico nell’Aldilà, a cura di Fr. Stella e Fr. Mosetti Casaretto, Pisa 2009 …

2011

Viene recensita l'ediz., con trad. ital., di Valafrido Strabone, La visione di Vetti. Il primo viaggio poetico nell’Aldilà, a cura di Fr. Stella e Fr. Mosetti Casaretto, Pisa 2009. Si tratta di un testo mediolatino di epoca carolingia, in esametri, nel quale viene narrata la prima "visione" poetica dell'aldilà (narrazione del viaggio dello stesso protagonista Vettino all'Inferno e al Paradiso).

Ricorda cosa ti hanno fatto in Auschwitz

2010

L'autore ricostruisce la genesi dell'opera di Luigi Nono e ne difende l'efficacia messa in dubbio dal dibattito sull'inefficacia del memoriale italiano di Auschwitz e sulla minaccia di un suo smantellamento ad opera dell' attuale direzione dell'ex-campo di concentramento

A Security Framework for Smart Ubiquitous Industrial Resources

2007

Conventional approaches to manage and control security seem to have reached their limits in new complex environments. These environments are open, dynamic, heterogeneous, distributed, self-managing, collaborative, international, nomadic, and ubiquitous. We are currently working on a middleware platform focused on the industrial needs, UBIWARE. UBIWARE integrates Ubiquitous Computing with Semantic Web, Distributed AI, Security and Privacy, and Enterprise Application Integration. In this paper, we describe our long-term vision for the security and privacy management in complex multi-agent systems like UBIWARE, SURPAS. The security infrastructure has to become pervasive, interoperable and inte…

La costruzione partecipata della vision aziendale: Proposta metodologica e studio di caso

2015

Introduzione Negli ultimi anni il sistema dei bisogni dietro le scelte di consumo si è evoluto verso una domanda di tipo esistenziale. Oggi i clienti cercano storie e valori cui aderire, che rappresentino l’identità di un’organizzazione differenziandola dalla concorrenza. Questo fenomeno ha stimolato il passaggio dal concetto di Branding (valori di marchio) a quello di Corporate Branding (valori organizzativi), spingendo le aziende a utilizzare sempre più diffusamente modelli di vision statement (es. carta dei valori) e a riconoscere un maggiore peso strategico della vision sullo sviluppo organizzativo: una visione forte fornisce valori che aiutano il conseguimento degli obiettivi aziendali…

Semantic Web Services for Smart Devices in a “Global Understanding Environment”

2003

Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…

Impact of Storage Acquisition Intervals on the Cost-Efficiency of the Private vs. Public Storage

2012

The volume of worldwide digital content has increased nine-fold within the last five years, and this immense growth is predicted to continue in foreseeable future reaching 8ZB already by 2015. Traditionally, in order to cope with the growing demand for storage capacity, organizations proactively built and managed their private storage facilities. Recently, with the proliferation of public cloud infrastructure offerings, many organizations, instead, welcomed the alternative of outsourcing their storage needs to the providers of public cloud storage services. The comparative cost-efficiency of these two alternatives depends on a number of factors, among which are e.g. the prices of the public…

Temporal Fairness Provisioning in Multi-Rate Contention-Based 802.11e WLANs

2005

The IEEE 802.11e extensions for QoS support in WLAN define the transmission opportunity (TXOP) concept, in order to limit the channel holding times of the contending stations in the presence of delay-sensitive traffic. We evaluate the use of TXOP for a different purpose: "temporal fairness" provisioning among stations employing different data rates. We show that the equalization of the channel access times allows each station to obtain its throughput basically (1) proportional to its transmission rate, and (2) independent of the transmitted frame length. This also improves the aggregate throughput of the overall WLAN. For a given TXOP limit, i.e., a granted channel access time, a station is…
