Venue

CIAC 2017 will take place in the Multimedia Amphitheater of the National Technical University of Athens, located in the basement of the building of NTUA's Central Library. See the map below:


You can arrive at the Central Library by various ways:

By public transport:

The easiest way is by taking the Blue Metro line (map) and getting off at the "ΚΑΤΕΧΑΚΗ" station. Then take the bus 242, get off at stop "ΘΥΡΩΡΕΙΟ" (you get off at the first stop inside the Campus) and walk 5 minutes towards the Central Library.

Another option is to take the bus 140 from the "ΚΑΤΕΧΑΚΗ" metro station and get off at stop "ΠΟΛΥΤΕΧΝΕΙΟΥΠΟΛΗ". Then get into the campus and walk 10 minutes towards the Central Library.

By taxi:

Taxi from the Katechaki ("ΚΑΤΕΧΑΚΗ") Station to NTUA will cost aproximately 3,5 €.

By car:

You can use this google map to get directions from Alimou-Katechaki Avenue.




Submission Guidelines

Authors are invited to submit an extended abstract of at most 12 pages by 23:59 AoE, Friday, November 11, 2016 (deadline extended). Submissions are handled by EasyChair at the following web page:

https://easychair.org/conferences/?conf=ciac2017

Submission Format: An extended abstract submitted to CIAC 2017 should start with the title of the paper, each author's name, affiliation and e-mail address, followed by a one-paragraph summary of the results to be presented. This should then be followed by a technical exposition of the main ideas and techniques used to achieve these results, including motivation and a clear comparison with related work. The extended abstract should not exceed 12 single-spaced pages (excluding references), using reasonable margins and at least 10-point font. If the authors believe that more details are essential to substantiate the claims of the paper, they may include a clearly marked appendix (with no space limit) that will be read at the discretion of the Program Committee. It is strongly recommended that submissions adhere to the specified format and length. Submissions that are clearly too long may be rejected immediately.

All submissions will be rigorously peer-reviewed and evaluated on the basis of the quality of their contribution, originality, soundness, and significance.

The proceedings of the conference will be published by Springer-Verlag in the ARCoSS/LNCS series and will be available for distribution at the conference. Accepted papers will be allocated 12 pages total in the LNCS format in the proceedings. Submissions are encouraged, though not required, to follow the LNCS format. More information about the LNCS format can be found on the author instructions page of Springer-Verlag.
