    Randomized Consensus in Wireless Environments

    In many emerging wireless scenarios, consensus among nodes represents an important task that must be accomplished in a timely and dependable manner. However, the sharing of the radio medium and the typical communication failures of such environments may seriously hinder this operation. In the paper, the authors perform a practical...

    Quantum Financial Economics - Risk And Returns

    Financial volatility risk is addressed through a multiple round evolutionary quantum game equilibrium leading to Multifractal Self-Organized Criticality (MSOC) in the financial returns and in the risk dynamics. The model is simulated and the results are compared with financial volatility data. The development of quantum game theory has led to...

    Resilient Business Process Management: Framework and Services

    In this paper, the authors contribute to extend Business Process Management (BPM) systems with resilience support. They applied concepts derived from resilience engineering and the study of hazards in highly reliable organizations to characterize resilient BPM. They developed a resilience framework based on two criteria, control, which may be prescriptive,...

    On The Emergence Of Critical Behavior In Evolving Financial Networks

    The authors introduce a simple model for addressing the controversy in the study of financial systems, sometimes taken as brownian-like processes and other as critical systems with fluctuations of arbitrary magnitude. The model considers a collection of economical agents which establish trade connections among them according to basic economical principles...

    Tourism And Growth In European Countries: An Application Of Likelihood-Based Panel Cointegration

    The tourism and economic growth relationship is investigated for a panel of European countries over the period 1988 - 2010. The results reveal that the variables contain a panel unit root and they cointegrate in a panel perspective. The findings show that tourism enhances economic growth for some countries in...

    The Dynamics Of The Trade Balance And The Terms Of Trade In Central And Eastern European Countries

    In this paper, the authors assess the existence of a S-Curve pattern in ten Central and Eastern European Countries (CEEC-10) for the relation between the trade balance and the terms of trade. Empirical results support the existence of this curve for Slovenia, Czech Republic, Hungary, and also for an aggregate...

    Applying Architectural Hybridization in Networked Embedded Systems

    Building distributed embedded systems in wireless and mobile environments is more challenging than if fixed network infrastructures can be used. One of the main issues is the increased uncertainty and lack of reliability caused by interferences and fading in the communication, dynamic topologies, and so on. When predictability is an...

    Flexible Operating System Integration in Partitioned Aerospace Systems

    The ARINC 653-based AIR (ARINC 653 in Space Real-Time Operating System) architecture, developed as a response to the interest of the aerospace industry in adopting the concepts of Integrated Modular Avionics (IMA), proposes a partitioned environment, observing strict temporal and spatial segregation, in which partitions are able to use different...

    An Endogenous Growth Model With Human And Social Capital Interactions

    Social capital has recently been introduced in the economic literature as a growth factor. In this paper, the authors study the interactions between social and human capital, and their contributions to economic growth in an endogenous growth model. In particular, they are interested in comparing the results from the theoretical...
