    Using the Right Two-Ray Model? A Measurement-Based Evaluation of PHY Models in VANETs

    The authors discuss the feasibility of simplified two-ray ground path loss models, which are frequently used in simulation-based performance evaluation of Inter-Vehicle Communication (IVC) protocols. They first show that these models are of no benefit compared to the basic Freespace model. As an alternative, they propose a more exact two-ray...

    Toward Realistic Simulation of Intervehicle Communication: Models, Techniques and Pitfalls

    The quality of Intelligent Transportation Systems strongly depends on the underlying communication protocols and techniques. In this paper, the authors discuss the current state of the art, trends, and open problems in the area of simulation techniques used to study Inter-Vehicle Communication (IVC). Complementary to testbed experiments that are often...

    Tructural Breaks In Inflation Dynamics Within The European Monetary Union

    To assess the effects of the EMU on inflation rate dynamics of its member states, the inflation rate series for 21 European countries are investigated for structural changes. To capture changes in mean, variance, and skewness of inflation rates, a generalized logistic model is adopted and complemented with structural break...

    Research Challenges in Inter-Vehicular Communication

    Inter-Vehicle Communication (IVC) has become an extremely hot topic in network research, opening up new research challenges well beyond those of classical Mobile Ad Hoc NETwork (MANET) research. In October 2010, a Dagstuhl seminar has been organized bringing together many of the internationally leading experts in this field to discuss...

    Deployment-Aware Energy Model for Operator Placement in Sensor Networks

    Query processing has become one of the main paradigms to approach information processing in Wireless Sensor Networks (WSNs). The authors study and identify relevant factors involved in in-network query deployment in WSNs. As a key outcome, they developed a deployment aware cost estimation model for distributing operators to nodes within...

    Monetary Policy And Its Impact On Stock Market Liquidity: Evidence From The Euro Zone

    The recent financial crisis has been characterized by unprecedented monetary policy interventions of central banks with the intention to stabilize financial markets and the real economy. This paper sheds light on the actual impact of monetary policy on stock liquidity and thereby addresses its role as a determinant of commonality...

    Equality, Equity And Incentives: An Experiment

    The authors devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects either vote on or exogenously encounter incentive settings while assigned...

    The Male-Female Gap In Physician Earnings: Evidence From A Public Health Insurance System

    Empirical evidence from U.S. studies suggests that female physicians earn less than their male counterparts, on average. The earnings gap does not disappear when individual and market characteristics are controlled for. This paper investigates whether a gender earnings difference can also be observed in a health care system predominantly financed...

    Semantic Web Service Choreography: Contracting and Enactment

    The emerging paradigm of service-oriented computing requires novel techniques for various service-related tasks. Along with automated support for service discovery, selection, negotiation, and composition, support for automated service contracting and enactment is crucial for any large scale service environment, where large numbers of clients and service providers interact. Many problems...

    A Dynamic Routing Mechanism for Network on Chip

    With an increase in the number of transistors on-chip, the complexity of the system also increases. In order to cope with the growing interconnect infrastructure, the "Network on chip (NoC)" concept was introduced. With network methodologies coming on-chip, various characteristics of traditional networks come into play. So far, failures that...

    Environmental Regulation And Investment: Evidence From European Industries

    This paper contributes to the empirical literature on the relationship between environmental regulation and firm behavior. In particular, the authors ask whether and how strongly investment decisions of firms respond to stringency in environmental regulation. Environmental stringency is measured as an industry's total current expenditure on environmental protection, and a...
