Resource Federations aim at providing access to information and communication technology (ICT) resources across the boundaries of administrative domains. This is of interest today as modern societies are concerned about ICT infrastructure energy consumption and need to improve the way ICT resources are provisioned and maintained. This paper describes a concept and prototype implementation for r...

Our work takes place in the context of the HLA standard and its application in real-time systems context. The HLA standard is inadequate for taking into consideration the different constraints involved in real-time computer systems. Many works have been invested in order to providing real-time capabilities to Run Time Infrastructures (RTI) to run real time simulation. Most of these initiatives ...

Database federations are employed more and more in situations involving virtual and integrated information on demand, e.g., real-time integration of two databases. Heterogeneity in hardware and software platforms, as well heterogeneity in underlying semantics of participating local databases, makes it a hard challenge to design a consistent and well-performing global database federation. The OR...

The emerging economic federations of the European Union, Russia, and South Africa, along with the established federations in Australia, Canada, and the United States, confront the task of designing the institutions for federal fiscal policy. This paper reviews the literature on the design of tax policy in federalist economies. We conclude that taxation by lower level governments can lead to sig...

The autonomic management of federated authorization infrastructures (federations) is seen as a means for improving the monitoring and use of a service provider’s resources. However, federations are comprised of independent management domains with varying scopes of control and data ownership. The focus of this paper is on the autonomic management of federated identity providers by service provid...

The Internet is rapidly evolving towards a multimedia service delivery platform. However, existing Internet-based content delivery approaches have several disadvantages, such as the lack of Quality of Service (QoS) guarantees. Future Internet research has presented several promising ideas to solve the issues related to the current Internet, such as federations across network domains and end-to-...

In recent years, the concept of peer-to-peer computing has gained renewed interest for sharing resources within and between organizations or individuals. This article describes a decentralized resource management system (DRMS) that uses a network of workstations for the execution and storage of high-level architecture (HLA) federations/federates in a peer-to-peer environment. The implementation...

TeraGrid has deployed a significant monitoring and accounting infrastructure to understand its operational success. In this paper, we present an analysis of the jobs reported by TeraGrid for 2008. We consider the workload from several perspectives: traditional HPC workload characteristics, grid-oriented workload characteristics, and finally userand group-oriented characteristics. We use metrics...

Following their practical needs and legal constraints, recent application of the cloud paradigm among public administrations has been focused on the deployment of private clouds. Due to the increasing amount of data and processing requirements, many organizations are considering possibilities to additionally optimize their infrastructures and collaborative processes by employing private cloud f...

the aim of this study was to investigate the role of job satisfaction in therelationship between organizational justices and turnover intention in expertsof sport federations. in this regard, wood job satisfaction (1986), kim andlung (2007) organizational justice, and cummann (1979) turnover intentionquestionnaires were used. the statistical population consisted of experts ofsport federations a...
