  • A distributed QoS Routing and CAC framework: performance evaluation of its SSRA and InterD Agents 

    Barolli, Leonard; Ikeda, Makoto; Durresi, Arjan; Xhafa Xhafa, Fatos; Koyama, Akio (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Conference report
    Open Access
    In order to support multimedia communication, it is necessary to develop routing algorithms which use for routing more than one QoS parameters. This is because new services such as video on demand and remote meeting systems ...
  • Improvement of JXTA protocols for supporting reliable distributed applications in P2P systems 

    Xhafa Xhafa, Fatos; Fernandez Correa, Raul; Daradoumis, Thanasis; Barolli, Leonard; Caballé Llobet, Santiago (Springer, 2007)
    Conference report
    Open Access
    In any distributed application, the communication between the distributed processes/nodes of the distributed systems is essential for both reliability and efficiency matters. In this work we address this issue for distributed ...
  • A security-aware approach to JXTA-overlay primitives 

    Arnedo Moreno, Joan; Matsuo, Keita; Barolli, Leonard; Xhafa Xhafa, Fatos (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Conference report
    Open Access
    The JXTA-Overlay project is an effort to use JXTA technology to provide a generic set of functionalities that can be used by developers to deploy P2P applications. Since its design mainly focuses on issues such as scalability ...
  • A fuzzy based call admission control scheme for wireless cellular networks considering priority of on-going connections 

    Mino, Gjergji; Barolli, Leonard; Durresi, Arjan; Xhafa Xhafa, Fatos; Koyama, Akio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Conference report
    Open Access
    The mobile cellular systems are expected to support multiple services with guaranteed Quality of Service (QoS).But, the ability of wireless systems to accommodate expected growth of traffic load and broadband services is ...
  • Efficient embedding of information and knowledge into CSCL applications 

    Caballé Llobet, Santiago; Daradoumis, Thanasis; Xhafa Xhafa, Fatos (Springer, 2007)
    Conference report
    Open Access
    This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, ...

  • An experimental study on peer selection in a P2P network over PlanetLab 

    Xhafa Xhafa, Fatos; Barolli, Leonard; Fernandez Correa, Raul; Daradoumis, Thanasis (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Conference report
    Open Access
    Peer selection is an important aspect in many P2P applications requiring efficient assignment and execution of jobs to peer nodes and search and file transfer, among others. Due to increasing interest of using P2P systems ...
  • Using computer-supported collaborative work in fundamental programming subjects 

    Xhafa Xhafa, Fatos; Vázquez Alcocer, Pere Pau; Marco Gómez, Jordi; Martín Prat, Àngela (Universitat de Girona, 2004)
    Conference report
    Open Access
    Fundamental Programming subjects are compulsory for several technical engineering degrees. Typical face-to-face teaching may cause a lack of continuous learning and support for students, as teachers are only available at ...
  • Optimization models of natural communication 

    Ferrer Cancho, Ramon (2018-07-03)
    Article
    Restricted access - publisher's policy
    A family of information theoretic models of communication was introduced more than a decade ago to explain the origins of Zipf’s law for word frequencies. The family is a based on a combination of two information theoretic ...
  • Spurious ambiguity and focalization 

    Morrill, Glyn; Valentín, Oriol (2018-06)
    Article
    Open Access
    Spurious ambiguity is the phenomenon whereby distinct derivations in grammar may assign the same structural reading, resulting in redundancy in the parse search space and inefficiency in parsing. Understanding the problem ...
  • Supraspinal modulation of neuronal synchronization by nociceptive stimulation induces an enduring reorganization of dorsal horn neuronal connectivity 

    Contreras Hernández, Enrique; Chávez, Diógenes; Hernández, E.; Béjar Alonso, Javier; Martín Muñoz, Mario; Cortés García, Claudio Ulises (2018-05-01)
    Article
    Restricted access - publisher's policy
    Despite a profusion of information on the molecular and cellular mechanisms involved in the central sensitization produced by intense nociceptive stimulation, the changes in the patterns of functional connectivity between ...
  • A parameterized halting problem, the linear time hierarchy, and the MRDP theorem 

    Chen, Yijia; Muller, Moritz Martin; Yokoyama, Keita (Association for Computing Machinery (ACM), 2018)
    Conference report
    Open Access
    The complexity of the parameterized halting problem for nondeterministic Turing machines p-Halt is known to be related to the question of whether there are logics capturing various complexity classes [10]. Among others, ...
