BEval: A Plug-in to Extend Atelier B with Current Verification Technologies

This paper presents BEval, an extension of Atelier B to improve automation in the verification activities in the B method or Event-B. It combines a tool for managing and verifying software projects (Atelier B) and a model checker/animator (ProB) so that the verification conditions generated in the former are evaluated with the latter. In our experiments, the two main verification strategies (manual and automatic) showed significant improvement as ProB's evaluator proves complementary to Atelier B built-in provers. We conducted experiments with the B model of a micro-controller instruction set; several verification conditions, that we were not able to discharge automatically or manually with AtelierB's provers, were automatically verified using BEval.Comment: In Proceedings LAFM 2013, arXiv:1401.056

Who watches the watchers: Validating the ProB Validation Tool

Over the years, ProB has moved from a tool that complemented proving, to a development environment that is now sometimes used instead of proving for applications, such as exhaustive model checking or data validation. This has led to much more stringent requirements on the integrity of ProB. In this paper we present a summary of our validation efforts for ProB, in particular within the context of the norm EN 50128 and safety critical applications in the railway domain.Comment: In Proceedings F-IDE 2014, arXiv:1404.578

The birth of roboethics

The importance, and urgency, of a Roboethics lay in the lesson of our recent history. Two of the front rank fields of science and technology, Nuclear Physics and Genetic Engineering, have already been forced to face the ethical consequences of their research’s applications under the pressure of dramatic and troubling events. In many countries, public opinion, shocked by some of these effects, urged to either halt the whole applications, or to seriously control them. Robotics is rapidly becoming one of the leading field of science and technology, so that we can forecast that in the XXI century humanity will coexist with the first alien intelligence we have ever come in contact with - robots. It will be an event rich in ethical, social and economic problems. Public opinion is already asking questions such as: “Could a robot do "good" and "evil”? “Could robots be dangerous for humankind?”

Where Have All the Symbols Gone?: A Study of Sufis and Sufi Symbolism in Ottoman Miniature Paintings

Ottoman miniature paintings represent some of the best preserved and documented works of Islamic art still extant. They differ critically from other forms of miniature painting, such as Persian miniature painting, by not representing Sufi symbolism. In the two potential sources of such symbolism, Ottoman Sufism and Persian miniature painters in the Ottoman Empire, appear to have not critically influenced Ottoman miniature painting to produce Sufi symbols, do to political, religious, and cultural factors. Instead, political factors of the Ottoman imperial state and the economics and standards of production in the empire produced an art medium where Ottoman Sufi symbols were not introduced
