Model-Driven Security (Mds) is a specialized Model-Driven Engineering (Mde) approach for supporting the development of secure systems. Model-Driven Security aims at improving the productivity of the development process and quality of the resulting secure systems, with models as the main artifact. Among the variety of models that have been studied in a Model-Driven Security perspective, one can ...

Despite the huge popularity of event processing nowadays, there is a big gap between the potential usefulness of event-driven processing and the current state of the practice. One of the main reasons is the lack of a comprehensive conceptual model for the event-triggered reactivity and the corresponding framework for its management. In this paper we survey the current state of the art in event-...

Both Model-Driven Software Development (MDSD) and Model Driven Architecture (MDA) emphasize the importance of precise machine-readable models and automatic transformations on these models. In this paper we identify the need to externally specify transformation units in terms of required and provided model properties. We also present shortly how one can use semantically rich transformation trace...

The model driven development is an interested area among software engineers as well as the agile development. In fact, combining model driven and agile practices is an interesting perspective for the software engineering. In this work, we present a case study of agile model driven development within the MIDAS framework, which composes a model driven architecture based on the Model Driven Archit...

This paper demonstrates that entrepreneurs who have created innovative organizations and service provision models are contributing to sustainable development. The processes, structures and outcomes of their initiatives are contrasted with more traditional efforts. World leaders have recently renewed the momentum for ‘buying’ sustainable development through massive allocation of development fund...

Applications running on a UNIX platform need to be notified when some activity occurs on a socket or other descriptor, and this is traditionally done with the select() or poll() system calls. However, it has been shown that the performance of these calls does not scale well with an increasing number of descriptors. These interfaces are also limited in the respect that they are unable to handle ...

Most theories of pragmatics and language processing predict that speakers avoid informationally redundant utterances. From a processing standpoint, it remains unclear what happens when listeners encounter such utterances, and how they interpret them. We argue that uninformative utterances can trigger pragmatic inferences, which increase utterance utility in line with listener expectations. In t...

Spreadsheets are widely used and studies show that most of the existing ones contain non-trivial errors. To improve end-users productivity, recent research proposes the use of a model-driven engineering approach to spreadsheets. In this paper we conduct the first empirical study to assess the effectiveness and efficiency of this approach. A set of spreadsheet end users worked with two different...
