Due to performance and certification criteria, complex mechanical systems have to take into account several constraints, which can be associated with a series of performance functions. Different software are generally used to evaluate such functions, whose computational cost can vary a lot. In conception or reliability analysis, we thus are interested in the identification of the boundaries of ...

The complexity of interactive systems results from partial knowledge that someone has on it. Such systems are specified by local properties and their global behavior is generally emerging. Managing the complexity is a permanent objective of the software engineering. Object oriented design has given place to several approaches aiming at controlling complexity: aspect programming which separates ...

The report issued by the Inquiry Board in charge of inspecting the Ariane 5 flight 501 failure concludes that causes of the failure are rooted into poor S/W Engineering practice. From the failure scenario described in the Inquiry Board report, it is possible to infer what, in our view, are the real causes of the 501 failure. We develop arguments to demonstrate that the real causes of the 501 fa...

The objective of this study was to identify faculty conceptions on evaluation in the Professional Practice Evaluation Exercise (PPEE). An analysis was performed on 155 evaluation instruments answered by the faculty, and video-recordings of four PPEE answered by 1st and 3rd year students.
