Foreword The Fourth International PhD Symposium in Engineering is organized in 2008 because it is thought that PhD students need a special forum in addition to their PhD programmes to present the results of their ongoing research. On the other hand the results should be discussed collecting proposals how to continue. The First, Second and Third International PhD Symposia were organized in 2005, 2006, 2007 and it will be important to continue this tradition. Objectives of the PhD Symposium • to provide a forum for PhD students in engineering to present the progress of their work, • to discuss the results of the ongoing PhD studies in order to support the future activity, • to give the opportunity for PhD students to establish contact for international communication, • to compare PhD studies in various countries. System of this symposium is to have oral presentations by the PhD students themselves, which are immediately followed by discussions that are scheduled in the programme. Main results of the studies are summarized in the Pollack Periodica (An International Journal for Engineering and Information Sciences) published by Akad´emiai Kiad´o. All of the abstracts and papers will be revied by the members of the Scientific Committee. On behalf of the Organizing Committee, I would like to express the thanks to the University of P´ecs, Pollack Mih´aly Faculty of Engineering for hospitality of the Symposium.
