June 13th: ACM 2014 program and information package

Dear ACM participants,

With just around two weeks to the beginning of ACM 2014 in Helsinki, we would like to inform you of several practical issues concerning the conference. With around 500 participants from 44 countries, we are anticipating an exciting meeting.

The contents of this letter are as follows:

We are hoping to see you soon!
On behalf of ACM Scientific and Local organizing committees,
Karri Muinonen and Antti Penttilä



We are happy to announce that the ACM 2014 scientific program is now available at
concerning both the oral and poster presentations!

For the assigned session chairladies and chairmen, please consider this posting and message as a kind invitation for you to act as chairs in the sessions indicated. Due to time and resource limitations, we have not been able to send individual inquiries. Let us know if, for one reason or another, you wish to introduce changes in your involvement. For those of you not yet having chair duties but wishing to become involved, let us know.


We will soon be ready with the editorial process to harmonize the language and format of the abstracts. You will be having an opportunity, for a short period of time, to comment on the proofs of your abstract(s). Further information on the schedule will be available next week.


For flight passengers: Most airlines arrive at the Helsinki-Vantaa airport. The taxi journey to central Helsinki costs ca. 40 euros. An alternative way is by bus 615 or 620, which takes you to the Railway Square. The bus tickets costs 5 euros and it can be purchased from the driver (cash only!). The bus leaves every 15-20 minutes.

The other options is to take the Finnair City Bus to the Railway station. The ticket costs 6.30 euros and can be purchased from the driver; credit cards are accepted. The Finnair City Bus is convenient for guests staying at the Unihome Töölö Towers, since it stops at "Hesperian puisto", from where the distance to the apartments is about 300 m. The map and timetable are at http://media.finnair.com/files/pdf/FINNAIR_CITY_BUS_TIMETABLE.pdf. Please note, that this is NOT a public transport bus and hence, public transport tickets are not valid on this route.

For train passengers: The trains from St. Petersburg and Moscow as well as secondary airport locations in Turku and Tampere arrive at the Central Railway station.

For ferry passengers: There are five different passenger ferry quay locations in Helsinki, please check http://www.portofhelsinki.fi/passengers for travel information.

The Helsinki city centre is covered with a convenient network of tram routes. At registration, we will be providing you with the public transportation ticket, which will be valid from Sunday June 29th to Saturday July 5th. Please refer to the map on our web-site at http://www.helsinki.fi/acm2014/venue.shtml.


On Sunday June 29th, there will be an ice-breaker party at the Helsinki Observatory
(see the map at http://www.helsinki.fi/acm2014/venue.shtml). New potatoes, strawberries, and other light food and drinks will be served. The band Rinne Rockers will play contemporary local and international favourites in the observatory garden at 17:00-17:30 and 19:00-19:30.

No fee is collected for the party, but we would appreciate if you could indicate your interest in attending the party through the following form:
so we could reserve the correct amount of food. The observatory will be open from 16:00 to 20:00, and you may come and go as you like. For those wishing to attend, there will be guided tours of the observatory every hour.

Registration will be open during the ice-breaker party.


To avoid congestion on Monday morning, there are two preliminary registration points open. A registration point is open during the ice-breaker party at the Helsinki Observatory on Sunday, June 29th. For those staying at the University guest house Unihome Töölö Towers, the registration will take place along with the check-in. The registration on site will open at 07:30 on Monday morning. The first session will begin at 08:30. Information about registration on Tuesday-Friday will be offered in the next posting.


Oral presentations: The scheduled time is either 8 minutes for the presentation + 2 minutes for the discussion (regular), 15 + 5 minutes (invited parallel) or 25 + 5 minutes (invited plenary). Presentations are accepted in PowerPoint (ppt, pptx), Adobe PDF (pdf), or OpenDocument Presentation (odp) format.

Videos and animations can be included in the slides, but one must remember to provide also the source files for these together with the presentation. PowerPoint users are advised to use "File – Save & Send – Package Presentation for CD" function to create a complete package including videos and animations.

Presentations must be tested and delivered to the ACM staff in the speaker-ready room (Meeting room 1 on the second floor) well before the session. Your own laptop can be used only in exceptional cases and must be tested with the ACM staff before the session.

Posters: Our poster boards are 95 cm (37.4") wide and 128 cm (50.4") tall. Posters of size A0 (84.1 x 118.9 cm) or posters printed on 36" (91.4 cm) wide paper will fit. You can see your poster location from the printed program. The posters are divided into two groups - one half will be presented from Monday to Tuesday and the other half from Thursday to Friday. The poster session is on those days from 10:30 to 12:00 (and during the coffee breaks).

We offer the possibility to have your poster printed and transported to the conference venue. This service costs 25 euros per poster. If you are interested, please let us know by June 17 by sending a message to acm-2014@helsinki.fi. The actual poster should be submitted by June 22. Acceptable formats are Adobe PDF (pdf) or PowerPoint (ppt, pptx).

June 4th: The conference program published

Dear ACM Colleagues,

Please see the scientific program of the ACM conference concerning the invited plenary talks (30 min including discussion), invited parallel talks (20 min including discussion), and ordinary oral talks (10 min including discussion). The rest of the scientific contributions are posters and we will be circulating the poster scheduling in a few days' time. The ACM SOC is acknowledged for essential help in program preparation.

Note that we have been able to provide a time slot for all colleagues desiring an oral presentation. Due to the large number of submissions, we have been forced to introduce four parallel sessions for the Monday-Thursday parts of the parallel program. Note also that a hard limit of two oral talks has been applied.

You will see that, at this point of the oral program preparation (although close to being final), the program does not yet include, for example, session names or indicators for particular entities of talks. However, we have spent much effort and time to produce a balanced program, where we have strived for minimizing harmful overlap while simultaneously taking into account the time intervals of participation for each individual participant. Thus, we would like to stress that there is significant inertia in introducing any changes in the oral program. (Please note, in particular, that the ACM LOC is composed of scientists and students who will need to complete their own ACM presentations amidst the conference organization! )

As to the strawberries and new potatoes, the local spring and summer season is ahead by several weeks and, for example, strawberries are expected already for the summer solstice (the season will last through the ACM meeting).

Hoping for today's weather to last (sunny and 27 deg C) and looking forward to seeing you soon in Helsinki!

With best regards,

Karri Muinonen
on behalf of ACM SOC and ACM LOC

May 14th: Presentation guidelines

The new presentation guidelines page gives practical information on the oral and poster presentations.

April 1st: Abstract system back online

March 31st: Advice for author/affiliation problems with the abstract submission

Last minute advice -- we have had reports that some of you are experiencing problems with author names or affiliations with the abstract submission form, especially if there are many authors/affiliations. For the time being, you can simply submit with one author and affiliation, and e-mail the complete list of authors/affiliations to us (acm-2014@helsinki.fi). We can correct the author list in the submitted abstract.

March 31st: Deadline for registrations with normal fee and for abstracts

Deadline for abstracts and registrations (normal fee) is today. In practice, the deadline is April 1st Finnish time since the LOC will already be sleeping when some of you will still submit from your own time zone within Monday :)

In case there is a problem with registration form or abstract submission, don't panic. Send us an e-mail and we will try to help on April 1st or 2nd. Your registration/submission will not be treated as 'late' in that case. Be patient with our answer, since our mailbox is quite full after today.
