    • People and Society - Social Networks - Incorporate autonomic characteristics into the control of social networks.
    • Autonomic computing is an approach to systems management that can give them the ability to perform management activities based on situations they observe in its environment. Social networks are groups of links that organize people, groups, and institutions in an equalitarian and democratic way around a common objective. Its members can collect and disseminate data, information, and knowledge in a collaborative way. For that, the design of the entire social network is very important and must be improved to facilitate the collaboration. This paper discusses how autonomic computing is being applied to improve the knowledge flow over social networks, and propose a generic architecture based on autonomic elements.

    • The success of the semantic web is intrinsically related to the use of ontologies. This important role given to ontologies in the semantic web implies increasing need for development and maintenance of domain ontologies, even with the scarcity of tools supporting the life cycle from creation to management and adaptation. In this article, we presented an ongoing doctoral work that focus on the Web knowledge representation available with domain ontologies and processing of this knowledge autonomously through a systematic evaluation and redesign of the ontology. The autonomic computing approach was used to provide the ability to adapt ontologies on the independent environment like the Web, where there is no restriction on the information being published, which can damage their quality.

    • Softwaretransparenz stellt eine neuartige und bedeutende Anforderung dar, mit der sich Softwareentwickler auseinandersetzen müssen. Da die Automatisierung in Wirtschaft und Gesellschaft generell zunimmt und die Bürger ihre Informationsansprüche geltend machen, erlangt die Transparenz öffentlicher Dienste und Prozesse grundlegende Bedeutung. Eine sachliche Auseinandersetzung ist nur möglich, wenn Verfahren, die die Öffentlichkeit betreffen, einer Beurteilung frei zugänglich sind.

    • Computer Networks - Wireless Sensor Networks & Security
    • Given the WSN nodes resource constrained characteristics,

Designing energy-aware applications, communication protocols and security mechanisms are critical. In this paper, we develop a comparison between two different operating systems (Contiki and TinyOS) running on the same hardware platform (Crossbow TelosB)in terms of energy consumption and execution time for different tasks.

    • A P2P swarm is self-sustaining if all its blocks are collectively held by peers. How does the self-sustainability vary as a function of content popularity, peers capacity and file size? Proposed model to analyse self-sustainability.
