We specify and detect periodic patterns in clinical data using a constraint-based pattern specification language. The language has been implemented within both a graphical knowledge acquisition tool and a pattern interpreter, both of which are implemented within a larger temporal abstraction architecture. We provide several examples of how to use the syntax of the pattern language to specify co...

Architectural patterns are a fundamental aspect of the architecting process and subsequently the architectural documentation. Unfortunately, there is only poor support for modeling architectural patterns for two reasons. First, patterns describe recurring design solutions and hence do not directly match the elements in modeling languages. Second, they support an inherent variability in the solu...

To give a consistent and more valuable feature on models, we propose that model-driven processes should be able to reuse the expert knowledge generally expressed in terms of patterns. In order to formalize and use them, some design pattern ontologies have been developed. To share them on the Web they have been implemented using the OWL language. They can be easily interrogated with dedicated qu...

Interactive narratives are an important element in video games and serious games alike, however, their authoring tools have their roots in programming language and programming environments. While these end-user environments for interactive narratives provide a means for users to create custom content, they are not necessarily intuitive or easy to use for non-programmers. This paper provides the...

This paper presents an approach for developing transformations from business process models to implementations that facilitates reuse. A transformation is developed as a composition of three smaller tasks: pattern recognition, pattern realization and activity transformation. The approach allows one to reuse the definition and implementation of pattern recognition and pattern realization in the ...

We review topics on formal language aspects of patterns. The main results on the equivalence and inclusion problems are presented. We discuss open problems, in particular, concerning pattern language decision problems and ambiguity in patterns .

Domain-specific pattern languages can be used to model applications, so that following particular paths in the pattern language lead to the complete design of particular systems. This paper shows how to use a pattern language-based analysis method and tool to help in the development of domain-specific systems, where the development is basically done at the analysis level. The requirements of th...
