Most major simulation federations are designed and constructed based on the professional experience of one or a few experts with extensive experience in creating such federations. Organizations have a risk of losing their understanding of federation performance if one of their key people is no longer available. As very little objective data on federation performance exists, it is difficult for ...

Federating the numerous existing networking testbeds offers multiple possible benefits, but so far testbeds and federation efforts remained semi-independent, and not wholly united as a single federation. We identify several problems against federation, namely, establishing new trust relations and agreeing on a common schema between the entities. In this paper we explore practical ways to set up...

Bitcoin, the first peer-to-peer electronic cash system, opened the door to permissionless, private, and trustless transactions. Attempts to repurpose Bitcoin’s underlying blockchain technology have run up against fundamental limitations to privacy, faithful execution, and transaction finality. We introduce Strong Federations: publicly verifiable, Byzantinerobust transaction networks that facili...

The research follows the evolution of number legitimate athletes, coaches and departments (clubs) within two sports federations: Romanian Basketball Federation Handball Federation. statistics show a different dynamic regarding athletes in period 1992-2019, study making comparison between federations terms management programmes impact thereof on dynamics departments. started from hypothesis that...

In this paper we present different algorithms to reduce the number of DBMs in federations by merging them. Federations are unions of DBMs and are used to represent non-convex zones. Inclusion checking between DBMs is a limited technique to reduce the size of federations and how to choose some DBMs to merge them into a larger one is a combinatorial problem. We present a number of simple but effi...

The objective of this study is to analyze, from a multi-theoretical framework, whether the managers Spanish National Sports Federations (NSFs) apply earnings management using accounting accruals as measure managerial discretion; secondly, these practices are associated with both level dependence on external resources, and economic financial control mechanisms exercised by Superior Council (Cons...

The computing models of the LHC experiments are gradually moving from hierarchical data models with centrally managed data pre-placement towards federated storage which provides seamless access to data files independently of their location and dramatically improve recovery due to fail-over mechanisms. Construction of the data federations and understanding the impact of the new approach to data ...

We present the concept and design of Dynamic Automated Metadata Exchange (DAME) in Security Assertion Markup Language (SAML) based user authentication and authorization infrastructures. This approach solves the real-world limitations in scalability of pre-exchanged metadata in SAML-based federations and inter-federations. The user initiates the metadata exchange on demand, therefore reducing th...
