The Electrimacs Conference Committee and the IMACS TC1 Committee invite you to come to Electrimacs 2014, organised by the Technical University of Valencia and the University of Tunisia El Manar. The 11th triennial international conference of the IMACS TC1 Committee will be held in Valencia in May 2014 and follows previous successful conferences held since 1984. Recent development of complex systems, such as distributed power systems, electrical vehicles and traction, renewable energy systems, spatial, airborne and naval applications have been made possible, to a great extent, due to widespread use of modelling and simulation techniques. These techniques are becoming more and more relevant as the complexity and interaction between systems increase. Electrimacs 2014 will be the place to share new ideas and developments in this field.
