The National Drug File Reference Terminology (NDF-RT) presents a large set of drug classes which can potentially be used in clincal settings. Using semantic web technologies such as XML (eXtensible Markup Language) and RDF (Resource Description Framework), the drug classes in NDF-RT were enriched for the purpose of comparison to themselves and to drug classes in other terminologies. Methods and...

An extension of the “Object Constraint Language” (OCL) for modeling real-time and reactive systems in the “Unified Modeling Language” (UML) is proposed, called OCL/RT. A general notion of events that may carry time stamps is introduced providing means to describe the detailed dynamic and timing behaviour of UML software models. OCL is enriched by satisfaction operators @η for referring to the v...

Elevating power estimation to architectural and behavioral level is essential for design exploration beyond logic level. In contrast with purely statistical approach, an analytical model is presented to estimate the power consumption in datapath and controller for a given RT level design. Experimental result shows that order of magnitude speed-up over low level tools as well as satisfactory acc...
