    The inherent complexity of business goal-models is a challenge for organizations that has to analyze and maintaining them. Several approaches are developed to reduce the complexity into manageable limits, either by providing ...
  • Logspace self-reducibility 

    Balcázar Navarro, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Text en actes de congrés
    Accés obert
    A definition of self-reducibility is proposed to deal with logarithmic space complexity classes. A general property derived from the definition is used to prove known results comparing uniform and nonuniform complexity ...
  • Supporting effective monitoring and knowledge building in online collaborative learning systems 

    Caballé Llobet, Santiago; Juan Pérez, Ángel Alejandro; Xhafa Xhafa, Fatos (Springer, 2008)
    Text en actes de congrés
    Accés obert
    This paper aims to report on an experience of using an innovative groupware tool to support real, collaborative learning. We base the success of on-line collaborative learning on extracting relevant knowledge from interaction ...
  • A GA(TS) hybrid algorithm for scheduling in computational grids 

    Xhafa Xhafa, Fatos; González, Juan A.; Dahal, Keshav P.; Abraham, Ajith (Springer, 2009)
    Text en actes de congrés

    Text en actes de congrés
    Accés obert
    Broadband satellite constellation networks will be required to carry all types of IP traffic, real time interactive traffic as well as non-real time traffic, warranting the need for appropriate QoS for these different ...
  • Using a grid platform for enabling real time user modeling in on-line campus 

    Caballé Llobet, Santiago; Xhafa Xhafa, Fatos; Daradoumis, Thanasis; Esteve, Joana; Barolli, Leonard; Durresi, Arjan (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Text en actes de congrés
    Accés obert
    User modelling in on-line distance learning is an important research field focusing on two important aspects: describing and predicting students' actions and intentions as well as adapting the learning process to students' ...
  • Evaluating A+B=K conditions in constant time 

    Cortadella Fortuny, Jordi; Llaberia Griñó, José M. (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Text en actes de congrés
    Accés obert
    The authors consider a type of condition that can be evaluated without requiring a complete ALU (arithmetic logic unit) operation. The circuit that is presented detects the condition A+B=K (n-bit numbers) in constant time, ...
