    A Proximity-Aware Load Balancing in Peer-to-Peer Based Volunteer Computing Systems

    One of the main challenges in peer-to-peer based volunteer computing systems is efficient resource discovery algorithm. Load balancing is a part of resource discovery algorithm and aims to minimize the overall response time of the system. This paper introduces an analytical model based on distributed parallel queues to optimize the...

    Enhancing Performance of Failure-Prone Clusters by Adaptive Provisioning of Cloud Resources

    In this paper, the authors investigate Cloud computing resource provisioning to extend the computing capacity of local clusters in the presence of failures. They consider three steps in the resource provisioning including resource brokering, dispatch sequences, and scheduling. The proposed brokering strategy is based on the stochastic analysis of routing...

    Efficacy of Fuzzy Representation of Knowledge for Integrated Management of Networked Systems

    For most modern networked systems, the traditional element-based management views are replaced by integrated management structures that take the nature of the enterprises and the services they provide into account. These complex systems need capabilities to accommodate for diverse areas, ranging from administration of elements to provision of services and...

    Evaluating the Performance of Distributed Approaches for Modal Identification

    In this paper two modal identification approaches appropriate for use in a distributed computing environment are applied to a full-scale, complex structure. The Natural Excitation Technique (NExT) is used in conjunction with a condensed Eigensystem Realization Algorithm (ERA), and the Frequency Domain Decomposition with Peak-Picking (FDD-PP) are both applied to...

    An Efficient Technique for Extracting Fuzzy Rules From Neural Networks

    Artificial Neural Networks (ANN) have the ability to model input-output relationships from processing raw data. This characteristic makes them invaluable in industry domains where such knowledge is scarce at best. In the recent decades, in order to overcome the black-box characteristic of ANNs, researchers have attempted to extract the knowledge...

    The Monetary Economy And The Economic Crisis

    The monetary economy has properties that cannot be analyzed using the tools of today's dynamic general equilibrium analysis. Keynes's economics, far from being an aberration in the otherwise orderly evolution of modern macroeconomics from Adam Smith's ideas about the "Invisible hand", was a major contribution to an ongoing tradition in...

    Towards Automatic Update of Access Control Policy

    Role-Based Access Control (RBAC) has significantly simplified the management of users and permissions in computing systems. In dynamic environments, systems are subject to changes, so that the associated configurations need to be updated accordingly in order to reflect the systems' evolution. Access control update is complex, especially for large-scale systems;...

    Information Asymmetries And Regulatory Decision Costs: An Analysis Of U.S. Electric Utility Rate Changes 1980 - 2000

    The authors argue that information asymmetries between regulators and firms increase the administrative decision costs of initiating new policies due to the costs of satisfying evidentiary or ''Burden of proof'' requirements. They further contend that regulators with better information about regulated firms - that is, with lower information asymmetries -...

    Social Security, Differential Fertility, And The Dynamics Of The Earnings Distribution

    Economists and demographers have long argued that fertility differs by income (differential fertility), and that social security creates incentives for people to rear fewer children. Does the effect of social security on fertility differ by income? How does social security change the cross-sectional relationship between fertility and income? Does social...
