In response to the call for papers 159 papers were submitted to the conference. These papers were evaluated on the basis of their signi?cance, novelty,and te- nicalquality.

Of the papers submitted, 27 were selected for presentation at the conference, giving an acceptance rate lower than 17%. The conference program also included an invited talk.

Thanks to all the members of the program committee, and the external reviewers, for all their hardwork in the paper evaluation. Due to the large number of submissions the program committee members were really required to work hard in a short time frame, and we are very thankful to them for the commitment they showed with their active participation in the electronic discussion.
