Context: Model-Driven Security (MDS) is as a specialised Model-Driven Engineering research area for supporting the development of secure systems. Over a decade of research onMDS has resulted in a large number

As an emerging solution to the handling of complex and evolving software systems, Model Driven Engineering (MDE) is still very much in evolution. The industrial demand is quite high while the research answer for a sound set of foundation principles is still far from being stabilized. Therefore it is important to provide a current state of the art in MDE, describing what its origins are, what it...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

Model-based development and in particular MDA [1], [2] have promised to be especially suited for the development of complex, heterogeneous, and large software systems. However, so far MDA has failed to fulfill this promise to a larger extent because of tool support being inadequate and clumsy and methodologies not being appropriate for an effective development. This article discusses what went ...

Model Driven Engineering (MDE) received a lot of attention in the last years, both from academia and industry. However, there is still a debate on which basic concepts form the foundation of MDE. The Model Driven Architecture (MDA) from the OMG does not provided clear answers to this question. This standard instead provides a complex set of interdependent technologies. This paper is the first o...

Refinement is a key practice in the Model-Driven Architecture initiative of the Object Modelling Group. However, the practice is loosely defined, overloaded, and open to misinterpretation. In this paper, we outline ongoing work on providing a precise definition for refinement via consistency checking, not only in the context of MDA, but more generally for model-driven development in a variety o...

Model-Driven Development (MDD) has become a familiar software engineering term in recent years, thanks to the profound influence of the Model Driven Architecture (MDA). Yet MDD, like MDA itself, defines a general framework, and as such is a generic approach rather than a concrete development methodology. Methodology support for MDA has been rather slow in coming, yet even though several MDA-bas...

In den letzten Jahren hat die von der OMG proklamierte, modellgetriebene Softwareentwicklung Model Driven Architecture (MDA) bzw. das Model Driven Engineering (MDE) in vielen Bereichen der Informatik an Bedeutung gewonnen. Bei diesem Vorgehen steht das Modell des zu realisierenden Systems im Vordergrund, welches iterativ mittels geeigneter Werkzeuge und Sprachen erstellt und präzisiert wird. Ab...

introduction: in this experimental study, the amount of smear layer (sl) remnants in curved root canals after chemomechanical instrumentation with two engine-driven systems or hand instrumentation was evaluated. methods and materials: forty-eight mesiobuccal roots of mandibular first molars with curvatures ranging between 25 and 35 degrees (according to schneider’s method) were divided into thr...

several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...
