Architecture styles characterise families of architectures sharing common characteristics. We have recently proposed configuration logics for architecture style specification. In this technical report, we study a graphical notation to enhance readability and easiness of expression. We study simple architecture diagrams and a more expressive extension, interval architecture diagrams. For each ty...

“The statistical problem of testing cluster validity is essentially unsolved” [5]. We translate the issue of gaining credibility on the output of un-supervised learning algorithms to the supervised learning case. We introduce a notion of instance easiness to supervised learning and link the validity of a clustering to how its output constitutes an easy instance for supervised learning. Our noti...

The paper presents a proposal of a method for MDA based “on-the-fly” modelling of Musical Real Time Applications. The method is based on use of the Executable and Translatable UML approach (xtUML) with regards to implementation on embedded systems. Since the goal is to implement a real-time application requiring certain real-time Quality of Service (QoS) properties, the real-time response requi...

System level tools are becoming more popular for designing different applications. In these tools, application designers describe their designs at high level using the powerful modeling environment such as MATLAB/Simulink. In this paper, SDFTool is presented as a design pattern and implemented as an add-on toolbox to address this issue. The three major functionalities offered by this view are: ...
