The IMECS 2011 is organized by the International Association of Engineers (IAENG), a non-profit international association for the engineers and the computer scientists. The conference has the focus on the frontier topics in the theoretical and applied engineering and computer science subjects. The IMECS conferences serve as good platforms for our members and the entire engineering community to meet with each other and to exchange ideas. Our IMECS committees have been formed with over three hundred conference committees members who are mainly research center heads, faculty deans, department heads, professors, and research scientists from over 30 countries. The last IMECS 2010 has attracted more than one thousand participants from over 50 countries.
