    Enhancing Collaboration Services with Business Context Models

    In this paper, the authors refine an organizational model to describe the execution of business activities. The model offers a dynamic, actor - centered, context - based and business process oriented perspective of the organization that explicitly addresses information, cooperation and collaboration needs derived from human multi - tasking capabilities....

    Network Game Based Routing for Energy Efficient Fibre-Wireless Access Networks

    The currently growing demand for Information and Communication Technologies (ICTs), and multimedia services, is generating a fast expansion of digital traffic. To fulfill such demands, new generation access architectures have been proposed that try to integrate and optimize available technologies. Besides allowing new services to emerge, such architectures also offer...

    The Additive Property Of The Inconsistency Degree In Intertemporal Decision Making Through The Generalization Of Psychophysical Laws

    Intertemporal decision making involves choices among options whose effects occur at different moments. These choices are influenced not only by the effect of rewards value perception at different moments, but also by the time perception effect. One of the main difficulties that affect standard experiments involving intertemporal choices is the...

    A Trust-Based Security Architecture for Small and Medium-Sized Mobile Ad Hoc Networks

    This paper describes trust based security architecture for small/medium-sized mobile ad hoc networks. The authors designed and implemented a security architecture that extends the traditional PKI model, assigning variable trust values to digital certificates and issuing credentials to grant access to network services. Trust values are not static; they vary...

    An Adaptive Multi-Level Hashing Structure for Fast Approximate Similarity Search

    Fast information retrieval is an essential task in data management, mainly due to the increasing availability of data. To address this problem, database researchers have developed indexing techniques to logically organize elements from large datasets in order to answer queries efficiently. In this context, an approximate similarity search algorithm known...

    Model for Simulation of Heterogeneous High-Performance Computing Environments

    This paper proposes a new model to predict the process execution behavior on heterogeneous multicomputing environments. This model considers the process execution costs such as processing, hard disk accessing, message transmitting and memory allocation. A simulator of this model was developed which help to predict the execution behavior of processes...
