You will have to answer questions on topics that occur in the lessons. You are expected to do a research work on the two papers proposed below, in a way to understand them and to be able to comment then. You must also take time to read complementary information in order to understand the papers. **Be sure to bring with you a copy of the two research papers as they will NOT be redistributed with the examination subject.** These can be annotated by you. The bibliography and appendices, if any, are part of the papers. * F. Faghri, D. J. Fleet, J. R. Kiros, S.

It will be an oral examination and it will he held remotely via zoom with these links: * Jean-Pierre Chevallet: https://univ-grenoble-alpes-fr.zoom.us/my/chevallj * Georges Quénot: https://univ-grenoble-alpes-fr.zoom.us/my/quenotg You will individually receive an email with the exact time at which you should reach these rooms. You will have 15 minutes with Georges Quénot and 15 minutes with Jean-Pierre Chevallet. There is no new paper to study for this session. Questions and/or exercises will be related to the papers selected for session 1 (above) with some related to the course in relation with the papers.
