Euro coins, entrepreneurship and X-ray fluorescence

During the first year of their master degree in Technical Engineering the students have to realized a large project. This year, we have decided to add an entrepreneurial aspect to the purely scientific aspect used until now, while focusing the students' attention on a customer oriented management of the project and on the project management itself, with the definition of accurate objectives, a planning time, the distribution of the tasks and responsibilities... This year, the retained subject is the study of the evolution of the precursors of our current euro coins, based on the fulfilling of numerous requirements as the ease to differentiate the coins by blind people, the possibility for automates to recognize the coins, the way the coins will interact with skin and perspiration, the magnetic properties of the coins... The project is the response of the nuclear group of ISIB to a concern of a Belgian numismatist. (authors)
