Abstract. As location-based applications become part of our everyday life, ranging from traffic prediction systems to services over mobile phones providing us with information about our surroundings, the call for more semantics and accurate services is emerging. In this work, we analyze and register the data semantics of Location-based Services (LBS). Initially, we categorize LBS data according...

The professional electronic commerce (Business-to-Business) relates to the computerization of the exchanges between companies and organizations or, in another term, it provides an inter-organization information system which makes it possible to do any type of automatic information exchange excluding any human intervention. In this context, handling data and knowledge information during the exch...

The nuclear magnetic resonance (NMR) spin relaxation rate constant in the rotating frame of reference R1 provides information on microsecond to millisecond ( s-ms) timescale kinetic processes that stochastically modulate the resonance frequencies of nuclear spins in molecules. Expressions for R1 are presented for two-site chemical exchange using both the conventional perturbation approach for e...

Introduction The American Recovery and Reinvestment Act of 2009 authorized the Centers for Medicare and Medicaid Services (CMS) to incentivize hospitals and physicians to become meaningful users of electronic health record (EHR) systems. In a final rule issued August 2012, CMS outlined the requirements for Stage 2 meaningful use to be effective in 2014 (1). The Stage 2 criteria require eligible...

In this article we give a survey of the current practice and state-of-theart of recommender services in scientific digital libraries. With the notable exception of amazon.com and CiteSeer which do not qualify as proper scientific libraries our survey revealed that in scientific libraries recommender services are still not in wide use – despite the considerable benefits they offer for students a...

The Storage Exchange is a new platform allowing storage to be treated as a tradeable resource. Organisations with varying storage requirements can use the Storage Exchange platform to trade and exchange storage services. Organisations have the ability to federate their storage, be-it dedicated or scavenged and advertise it to a global storage market. This thesis provides a detailed account of t...

Electronic Government offers citizens and businesses a single interface to all public services, implemented through cross-agency processes and applications. This paper presents a fragment of a software infrastructure that enables agencies to collaborate in the delivery of public services, responsible for automated, process-driven exchange of messages between applications. In addition to basic m...

Future wireless communication environments offer many possibilities for new services. Users will not be satisfied with simply being connected, but they will require useful services built on top of the wireless networks. iClouds is an architecture which offers spontaneous mobile user interaction, collaboration, and transparent data exchange in mobile ad hoc networks. In this paper we present sev...
