La più popolare forma di Intelligenza Artificiale attuale è rappresentata da potenti strumenti di statistica computazionale che, pur essendo privi di qualsiasi capacità di ragionamento generale causale di tipo umano, imitano in modo assai efficace abilità complesse ritenute di pertinenza del nostro intelletto. Esiste grande incertezza riguardo ai b...

This paper presents the SUNRISE GATE, namely the interface through which users can run their experiments, accessing in a unified way the heterogeneous resources offered by the testbeds of the SUNRISE federation (http://fp7-sunrise.eu).

Open Altra Economia" (OAE) is an Italian R&D project experimenting with Open Data and Open Source Software (OSS) to advance the cause of "Altra Economia Lazio" (AEL), a consortium of social and economic structures whose main principles are based on equity, solidarity, efficiency and sustainability. These concepts are also at the core of degrowth an...

Although the sector of renewable energies has gained a significant role, companies still encounter considerable barriers to scale up their business. This is partly due to the way data and information are (wrongly) managed. Often, data is: partially available, noisy, inconsistent, sparse in heterogeneous sources, unstructured, represented through no...

This paper describes the design, implementation and experimental evaluation of a progressive privacy solution for a DaaS system. Progressive privacy is a privacy preserving model which can be configurable (possibly on-demand) by a user not only quantitatively but rather qualitatively. The user can discriminate what type of information must be prese...

In public clouds, where data are provided to an infrastruc-ture hosted outside user's premises, privacy issues come to the forefront. The right to act without observation becomes even more important in Desktop-as-a-Service (DaaS) environments. This paper describes the de-sign, implementation and preliminary experimental evaluation of a pro-gressive...

In this chapter we demonstrate how to increase the value of shared information by providing context on its quality via trust metrics. In order to evaluate the achieved level of trust, a trust evaluation system is described. This system assesses the quality of information based on past behaviour, direct experience, recommendation, referral, and role...

Utility computing can occur at different levels. Prom Software- as-a-Service (SaaS) paradigm, Desktop-as-a-Service (DaaS) paradigm can be derived: desktops can be transformed into a cost-effective, scalable and comfortable subscription service. In VDD, desktop virtual machines are instantiated on a server and then provided to clients as a whole, on...

Obsolete hardware can be effectively reused through intelligent software optimization, which is possible only when source code is available. Virtual Distro Dispatcher (VDD) is a system that produces virtual machines on a central server and projects them on a number of costless physical terminals. VDD is the result of an extreme software optimisatio...

Diffusion of ICTs created the issue of an enormus quantity of old computers to be discarded (e-Waste). Sustain-able dismantle is becoming a global enviromental emergency. In this scenario, Trashware movement is spreading worldwide to give to computers the correct time of obsolescence and to face the ecological problem related to e-waste. Workgroups...

SLAng is an XML language for defining service level agreements, the part of a contract between the client and provider of an Internet service that describes the quality attributes that the service is required to possess. We define the semantics of SLAng precisely by modelling the syntax of the language in UML, then relating the language model to a...

Syntax of SLAng 3. The semantic definition forms an objective basis for definitions of relationships between SLAs, in particular matching desired service levels to o#ered service levels as required for inter-service composition.

SLAng is an XML language for defining service level agreements, the part of a contract between the client and provider of an Internet service that describes the quality attributes that the service is required to possess. We define the semantics of SLAng precisely by modelling the syntax of the language in UML, then embedding the language model in a...

Application or web services are increasingly being used across organisational boundaries. Moreover, new services are being introduced at the network and storage level. Languages to specify interfaces for such services have been researched and transferred into industrial practice. We investigate end-to-end quality of service (QoS) and highlight that...

Il valore aggiunto rappresentato dalla conoscenza nelle moderne economie dei paesi sviluppati si riflette in maniera automatica a livello internazionale e finisce naturalmente per interessare tutte le economie e le vite dei popoli del pianeta. Ricco diviene chi possiede conoscenza. Povero chi non possiede conoscenza. L'associazione Ingegneria Senza...
