Iulian Popescu, Emeritus Professor, Ph.D. in engineering, is a full member of the Academy of Technical Sciences of Romania. He was teaching the course on Mechanisms and Machines Theory at the Faculty of Mechanics of the University of Craiova, Romania, for about 35 years. He supervised 25 PhD students and published 31 books on Mechanisms in Romanian language.    Liliana Luca, Ph.D., serves as a Professor at the Faculty of Technical, Medical and Behavioral Sciences of the University Constantin Brancusi, Targu-Jiu, Romania. She has received her Ph.D. degree from the University of Craiova, Romania, in 2000. She has authored 6 books on Mechanisms in Romanian language and more than 100 articles published in indexed journals and proceedings of national and international symposiums. She has received the Best Paper award (2012) for "Studies regarding generation of aesthetics surfaces with mechanisms",published in the  Proceedings of the 3rd International Conference on Design and Product Development, Montreux, Switzerland, ISBN 978-1-61804-148-7.   Mirela Cherciu has served as an associate professor at the Faculty of Mechanics, University of Craiova and holds a Ph.D. in mechanical engineering (2000). Under the guidance of the emeritus professor Iulian Popescu, she has made some important contributions on the topic of precision of the mechanics, which have been described in her Ph.D. thesis, examined at the University of Craiova in 2000, and in a number of publications, including 5 books in Romanian language and 70 scientific papers published in in national and international conferences.   Dan B. Marghitu is a professor of mechanical engineering in the College of Engineering at Auburn University, US.  He holds a Ph.D. from Southern Methodist University, Dallas, Texas and a DEA from Paul Sabatier University, Toulouse, France.  Dan B. Marghitu has published over 70 research papers in journals and has authored and co-authored 6 textbooks in the areas of dynamics, robotics, and mechanisms.  His research covers impact dynamics with applications to robotics systems, and nonlinear dynamics with application to human and animal locomotion.  Dan B. Marghitu has served as a PI/Co-PI of funded projects, and organized and chaired many international conferences.
