We present a UML 1.5 profile named TURTLE (Timed UML and RT-LOTOS Environment)
endowed with a formal semantics given in terms of RT-LOTOS. TURTLE relies on UML's …

Many researchers have evaluated different parts of UML™ and have come up with
suggestions for improvements to different parts of the language. This chapter looks at UML …

With the increasing popularity of the Internet, electronic commerce, and enterprise
applications, UML and the Unified Process has been developed to Focus on Unified …

Synchronous Programming (SP) is a universal computational principle that provides
deterministic concurrency. The same input sequence with the same timing always results in …

In this article, a formal generic framework for defining and reasoning about deterministic
concurrency in synchronous systems is implemented in the Spin model checker. Concretely …

The language μ-Charts is one of many Statechart-like languages, a family of visual
languages that are used for designing reactive systems. We introduce a logic for reasoning …

Pervasive computing implies new challenges for software developers. In addition to tackling
common problems pertaining to IT systems in general, new issues like mobility and context …

Synchronous Programming (SP) is a model of computation that supports concurrent thread
composition and provides deterministic observable behaviour. A recent theory has extended …

To deal with the increasing complexity of digital systems, the model driven development
approach has proven to be beneficial. This paper presents a model driven hardware design …

The paper discusses the use of the TURTLE UML profile to model and verify service
continuity during dynamic reconfiguration of embedded software, and space-based …
