Cloud computing is a technology of enormous scope for innovation especially in a volatile market and rapidly evolving, in which, the ability to exploit new technologies and remaining competitive is more important. However the choice of Cloud providers, whose offers best fit the requirements of a particular application, is a complex issue due to the variety(More)
The selection of Cloud providers, whose offers best fit the requirements of a particular application, is a complex issue due to the heterogeneity of the Cloud services, resources, technology and service levels offered by the several providers. In this paper, we illustrate a model for the resolution of a problem of choice between alternatives, when numerous(More)
The selection of Cloud providers, whose offers best fit the requirements of a particular application, is a complex issue due to the heterogeneity of the Cloud services, resources, technology and service levels offered by the several providers. In order to support this selection and requirements specification, we have developed, in the context of the mOSAIC(More)
In goal oriented problems, decision-making is a crucial aspect aiming at enhancing the ability to make decisions by full autonomous, or supervised software agents. Agents usually resolve a huge number of evaluations and decisions without the user intervention. Just the remaining uncertainty should be left to the user’s attention. In this paper we present a(More)
The increasing complexity of services required by users in Cloud Environments usually needs the definition of composite, value added services (VAS). Usage patterns and Use Cases definitions help in defining VAS, but a way to assure that new services reach the required goals with proper qualitative and quantitative properties has to be provided in order to(More)
Mobile devices can be used to improve the exploitation of reality by the user in pervasive environments. In this paper we present a software framework for augmenting the user's perception of reality by innovative applications and services. Mobile applications enable handheld devices to get information from pervasive sensors, as their own perceptors, in(More)
MOTIVATION  When considering renewable energy sources, like solar electricity, people often do not directly see the benefit of their investment.  While the sun is shining and might be producing electricity in their homes, they are at their work and cannot use that energy directly MOTIVATION
agents are autonomous, reactive and pro-active problem solvers. They co-operate to achieve the overall goal of a system. Numerous systems are based on mutual support and/or competition of agents, which are developed to satisfy the queries of a human user. Systems of multi-agent acquirement (agencies) extracting clear information for the user have been(More)
