Today, many cloud Infrastructure as a Service(IaaS) frameworks exist. Users, developers, and administrators have to make a decision about which environment is best suited for them. Unfortunately, the comparison of such frameworks is difficult because either users do not have access to all of them or they are comparing the performance of such systems on(More)
The problem of fusing beliefs in the Dempster-Shafer belief theory has attracted considerable attention over the last two decades. The classical Dempster’s Rule has often been criticised, and many alternative rules for belief fusion have been proposed in the literature. We show that it is crucial to consider the nature of the situation to be modelled and to(More)
A similarity measure between the focal elements used on a distance function of two basic belief assignments in the theory of evidence is presented, making way for the application of classical classification algorithms in this field. The properties of this measure are particular to its context, considering the characteristics of the focal elements, their(More)
Reducing the gap between the definition, modeling and management of business definition, modeling and management of business processes and the realization of the main processes functions through software services requires a methodological approach. Addressing such gap, this paper focuses on the interactions between the activities of a business process and(More)
— In this document we briefly outline some differences between IaaS frameworks Eucalyptus, OpenNebula, OpenStack and Nimbus. We provide also an overview how platforms such as Amazon, Azure, and Google provide additional services to provide more convenient platforms for its users. We than present an overview of what FutureGrid currently provides while also(More)
Dempster’s Rule is commonly described as an operator for fusing beliefs. While there are different possible interpretations of belief fusion, there is considerable confusion regarding the exact type of belief fusion that Dempster’s rule performs. Many alternative operators for belief fusion have been proposed, where some are based on the same fundamental(More)
The future power system integrated a large share of distributed generation (DG) may causes a reduction of the system rotational inertia, resulting in high frequency variations with any disturbances. An additional rotational inertia will be provided to the system if many DG units combined with relative small storage systems operate like virtual synchronous(More)
Future Grid (FG) is an experimental, high-performance test bed that supports HPC, cloud and grid computing experiments for both application and computer scientist. Future Grid includes the use of virtualization technology to allow the support of a wide range of operating systems in order to include a test bed for various cloud computing infrastructure as a(More)
This paper describes an approach to demonstrate the operation of virtual synchronous generators (VSG) in practical distribution systems. After an extensive simulation phase at laboratory scale, the field demonstration is planned at two sites located in the Netherlands and in Romania, for small VSGs of 10 × 5 kW and one large VSG of 100 kW(More)
