Dr Jozsef Farkas is a professor of Metal Structures. He graduated in 1950 at the Faculty of Civil Engineering of the Technical University of Budapest. He teaches at the University of Miskolc since 1950, as a university professor since 1975. His academic scientific degrees: Candidate of technical science 1966, doctor of technical science 1978. His research field is the optimum design of metal structures, residual welding stresses and distortions, tubular structures, stiffened plates, vibration damping of sandwich structures. He has worked out expert opinions for many industrial problems, especially in the case of storage tanks, silos, cranes, welded press frames and other machine structures. He is the author of a university textbook about metal structures, an English book 'Optimum design of metal structures' (Ellis Horwood, Chichester 1984) and about 140 scientific articles in journals and conference proceedings. He is a Hungarian delegate of the International Institute of Welding (IIW), member of the International Society for Structural and Multidisciplinary Optimization (ISSMO) and a presidential member of the Welding Division of the Hungarian Scientific Society of Mechanical Engineers. Dr Karoly Jarmai is a professor in the Faculty of Mechanical Engineering at the University of Miskolc, Hungary. He graduated as a certified mechanical engineer and received his doctorate (dr. univ.) in 1979 at the University of Miskolc. He teaches design of steel structures, welded structures, composite structures and optimization in Hungarian and in English language for foreign students. His research interest includes structural optimization, mathematical programming techniques and expert systems. He made his C.Sc. (Ph.D.) dissertation at the Hungarian Academy of Science in 1988. He became European Engineer (Eur. Ing., FEANI, Paris) in 1990. He has got the habilitation (dr habil.) at the University of Miskolc, in 1995. He has defended his D.Sc. thesis at the Hungarian Academy of Science with the economic design of different steel structures, optimization and expert systems in 1995. He has published over 120 technical papers, student aids, textbook chapters and conference papers. He is member of ISSMO and the Hungarian delegate in IIW. He is the Deputy Secretary General of the Scientific Society of Mechanical Engineers (GTE) in Hungary and president of this society at the University of Miskolc.
