Biologists and biotechnologists need to draw information from numerous distributed and heterogeneous resources, such as online biomedical databases, nomenclatures and specialised bioinformatics tools. These tasks can benefit significantly from semantic data federation with SADI Semantic Web services where multiple resources exposed through SADI services are accessed as a single virtual SPARQL-q...
This paper suggests a definition of the term Cloud Federation, a concept of service aggregation characterized by interoperability features, which addresses the economic problems of vendor lock-in and provider integration. Furthermore, it approaches challenges like performance and disaster-recovery through methods such as co-location and geographic distribution. The concept of Cloud Federation e...
We study the occupation measure of various sets for a symmetric transient random walk in Z with finite variances. Let mn ðAÞ denote the occupation time of the set A up to time n. It is shown that supx2Zd m X n ðx þ AÞ= log n tends to a finite limit as n ! 1. The limit is expressed in terms of the largest eigenvalue of a matrix involving the Green function of X restricted to the set A. Some exam...
