Complex Networks - SocioPatterns project In collaboration with the Institute for Scientific Interchange Foundation through Prof. Ciro Cattuto since July/2009, the participation in the SocioPatterns project is an opportunity of integration with the Complex Networks community. The SocioPatterns project aims to shed light on patterns in social dynamics and coordinated human activity. It do so by developing and deploying an experimental social interaction sensing platform. This platform consists of portable sensing device and software tools for aggregating, analyzing and visualizing the resulting data.

Google Summer of Code 2010 In April 2010, a project proposal with the Gephi development team has been accepted for the Google Summer of Code program. The program is the best way for students around the world to start contributing to an open-source project. Gephi's project aims to bring the perfect tool for visualizing and manipulating networks, focusing on usability, performance and modularity. The project timeline started at May 24 2010 and ended at August 16 2010.

RD-PVR: Recommendation & Discovery for Personal Video Recording The goal of this project is to use events discretization combined with a collaborative filtering approach to make good predictions of user's registrations, in the Personal Video Recording services domain. The approach is based on the analysis of real data generated by the Faucet PVR system, integrated in a web-based podcasting.

DeHinter DeHinter is a Peer-to-Peer (P2P) recommender system that exploits social filtering techniques in order to implement a fully decentralized resource sharing platform. The system provides to users a way to share, search and retrieve contents in a scalable, flexible and efficient way. The spontaneous relationships between users that show similar interests shape highly connected thematic clusters that can be exploited to provide personalized advices. DeHinter's goal is to reduce the impact of the information overload provinding a decentralized, autonomous and efficient way to filter contents exploiting social-oriented phenomena.

GigaManP2P The management of long distance backbones based on high speed optical networks requires new solutions for challenging tasks. For instance, operators and users located at different administrative domains must communicate with each other in order to configure and monitor agreed quality of service levels. This project proposes a novel peer-to-peer (P2P) management architecture for optical networks, focused initially on the new RNP Giga backbone. In the proposed architecture, peers provide, in a ubiquitous fashion, management information to modules that interface with both the optical infrastructure and network users. This project also presents preliminary experiments carried out in order to evaluate the processing overhead imposed by the P2P infrastructure on the SNMP-based management platform.
