The PRIME 2013 conference will be held in Villach, Austria. PRIME is a very special event since it is the one conference specifically dedicated to Ph .D. students, who have to present all the contributions. By Ph. D. student we mean a student who is working toward his/her Ph. D. thesis or who has discussed his/her Ph. D. thesis within one year in advance of the paper submission deadline. In addition to the Ph. D. student presentations, at PRIME 2013 every day from June 24th to 26th, 2013 in the afternoon there will be a time slot (Company Fair) dedicated to establish new contacts between Ph. D. students and institutions (research centers, universities, and companies) for the creation of future joint activity (like, for instance, fellowships, internships, or also employment). Finally on June 27th, 2013 there will be a Short Course on "Power IC and Discrete Technologies", as well as a visit to Infineon Technologies Austria AG. All the papers presented at PRIME 2013 will be published on the IEEExplore database, giving a large audience and so popularity and interest to the event.
