Welcome to IOMAC This is a historic event, for the first time ever people gather to exchange experience and research results in field of Operational Modal Analysis. This is a new field, and we are still confused about what to call this technology; is it “operational modal analysis” like the mechanical people like to call it, is it “ambient modal” like the civil engineers like to call it, or is it something more colourless like “output only modal” or something more green like “natural input modal analysis”? We do not know the answers for now, but that does not matter much. We all know that this field is interesting to us, it gives us new possibilities, either to invent new techniques in modal testing and identification, or it gives us new possibilities for doing research in related fields like monitoring or updating. It does not matter that we cannot agree on what we call it, or why we like it; the only important thing is that we have our interest for this technology in common. Because of that we all gain from coming together telling about what we do and listening to what other people are doing. We are very lucky, because we are stepping on new land, just like traditional modal analysis did 30 years ago. All the new possibilities are in our hands, we are the ones who can write the core literature in this field, because the major part of this literature still remains to be written. IOMAC will be a gathering factor for this process, but IOMAC is just a frame; when you and all the other people join, the picture is complete; we will be in front of this technology development. Let us create an open environment for exchange of our ideas and experiences, let us be a community for creation, let us be science and application, and let us stay with an open mind. Let us be conscious about our basis and our foundation, the classical modal analysis, let us be respectful to the past, but let us at the same time not constrain any possibilities. Let us have open discussions at this conference, but let us be respectful to all point of views. Let us be the lead, and be open, not make an exclusive club, but let us welcome anybody who shares this same interest. I’m looking forward to hearing your papers and to hearing your comments on this conference – and not least – to seeing you all in Copenhagen. Rune Brincker Conference Chair

Briefing speakers and chairs Presentation Guidelines Please bring your presentation (PPT file) on cd or memory stick. • There will be a computer at your disposal in the lecture room – you need not bring your own pc. This minimizes preparation time for the sessions • Before the session starts all speakers must meet the chairman of the session in the lecture room 15 min. before session start. The chairman will at this time install your PPT file on the computer and check the introduction information of the speakers. • Your presentation should last maximum 10-13 minutes leaving room for questions from the audience. • Please note: If your presentation exceeds 15 minutes, you will be asked to conclude, since the total time for presentations including questions and introduction of the next speaker is 20 minutes. • You are advised to concentrate on presenting the key issues of your paper and avoid mathematical details that might be found in the paper.

Location information Local currency Please note that the official currency in Denmark is Danish Kroner (DKK) and that 1 EUR corresponds to 7.45 DKK

Weather information The average day temperature at the end of April in Denmark is about 10 degrees centigrade, but with strongly varying maximum and minimum temperatures. A (usually reliable) weather forecast one week ahead can be seen from http://www.dmi.dk

About the conference venue Copenhagen Admiral Hotel, Toldbodgade 24-28 - DK-1253 Copenhagen K, Denmark, Tel. +45 33 74 14 14 Fax +45 33 74 14 16, E-mail: [email protected]. Web site: http://www.admiral-hotel.dk. The hotel is located in an old warehouse stone building at the old harbour area Nyhavn. The location is within walking distance from the downtown area including the famous Little Mermaid, The Queen’s Castle, the old Tivoli Garden of Copenhagen and the commercial downtown centre with narrow shopping streets and the central pedestrian street. Harbour channel cruises through the historic centre of Copenhagen are available near by. More information about Copenhagen at http://www.woco.dk

How to get there From Copenhagen Airport: By taxi to Nyhavn: It takes about 20 minutes by taxi to Nyhavn (dependent on traffic), price 150-200 DKK. By train to Copenhagen Main Station: From Copenhagen International Airport (Terminal 3) there are train services to Copenhagen Central Station (tickets to be bought before you get on the train, price 22.50 DKK). From the main station you have four options: Take a taxi to the hotel (at 60-70 DKK): When you arrive at the main station by trail you should use the exit to Bernstorffsgade, and you will find taxis right outside. It is also possible to go by bus (at 17 DKK). Use the exit to Vesterbrogade and catch bus no. 29 from the bus stop at Vesterbrogade. Tickets can be bought from the bus driver. The trip takes 8-10 mins. and you should get off at the Nyhavn stop. Or you may change to the Copenhagen Metro at the main station. You should get off at the Kgs. Nytorv stop. If your decide to walk, it might be a good experience if you do not have much luggage with you, the walk is approximately ½ hour. You simply walk north-east on the walking streets towards the Queens Palace. Just between Nyhavn (the old harbour area with the many bars and restaurants) and the Queens Palace – just at the harbour front – is the conference hotel.
