Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):Information technology is changing industry practices around the world.
Building Information Modeling (BIM) is currently replacing old 2D-drawing practices in the construction industry and is a fundamentally different way of creating, using and sharing building design data.
Regardless of the latest development of 3D design and other BIM tools, management of that design information is still in its infancy.
Designing and constructing building requires multi-disciplinary collaboration.

Because the nature of construction process collaboration and data sharing among different disciplines are very important.
Large projects the amount of data can be enormous and errors due to bad communication between disciplines are prone to happen.
Recently, it was believed that the BIM server would be the answer to these communication and data sharing problems.
Server would be the repository for all design data and every discipline could update its own specific data to that repository for others to view.
One example, that the architect uploads an architectural model to the BIM server and structural and mechanical designer could then use that model as a reference for their own work.
Afterwards, this resolution has been proven to be very difficult to implement in practice.

Aalto University has been researching new concept collaboration with Tekla Oy and a few other smaller software companies.
This new concept relies on distributed information management.
All design information is stored in client computers and data is published at the time the designer feels it is ready and after publishing all other disciplines can subscribe to needed information from the other client repositories.

Information sharing is a very fundamental problem in construction industry at the moment.
The IFC file format has been industry standard for data sharing, but because of fast development of building information modeling, it is already an outdated method for multidisciplinary collaboration.
While IFC is currently industry standard it is not efficient enough for fluctuating demand.
There are numerous fundamental problems with IFC as data exchange format.
It is clear that mere IFC file format is not enough, hence some kind of data sharing concept is needed.
BIM-server as an exchange platform is promising step towards true collaboration, but it can be hard or even impossible to implement functionally enough.

However, if centralized file management is changed to distributed file management, it could solve all the data sharing problems.
Even though this concept is not yet ready, it is most promising data sharing concept and hopefully it will become industry standard in the future.
Abstract (fin):Informaatioteknologia muuttaa teollisuuden käytäntöjä ympäri maailmaa.
Rakennuksen tietomallinnus on korvaamassa perinteisen 2D-suunnittelun rakennusteollisuudessa.
Tietomallinnus on aivan uudenlainen tapa luoda, käyttää ja jakaa rakennuksen suunnittelutietoa.
Vaikka 3D suunnittelun työkalut ovat kehittyneet paljon viime vuosina, mallitiedon hallinta on vielä aivan alkutekijöissään.

Rakennusprosessi on luonnoltaan sellainen että se vaatii monen osapuolen yhteistyön ja kaiken informaation jakaminen osapuolten kesken on erittäin tärkeätä.
Isoissa projekteissa suunnittelu datan määrä on valtava, ja kommunikaatio katkoksista aiheutuu helposti isoja virheitä.

Ratkaisuksi tiedonjakamisen ongelmiin on aiemmin ehdotettu BIM serveriä.
Tämä serveri olisi varasto kaikelle suunnittelutiedolle ja eri osapuolet voisivat tallentaa oman alan suunnittelutiedon muiden osapuolten nähtäväksi.
Esimerkiksi kun arkkitehti tallentaa omat luonnokset BIM serverille, voi sekä LVI että rakennesuunnittelija käyttää tätä tietoa referenssinä omiin suunnitelmiinsa.
Jälkeenpäin tämä ratkaisu on osoittautunut vaikeaksi toteuttaa käytännössä.

Aalto yliopisto on tutkinut uutta konseptia yhteistyössä Tekla Oy:n ja muutaman muun pienemmän ohjelmistoyrityksen kanssa.
Uusi konsepti luottaa hajautettuun tiedonhallintaan.
Kaikki data on tallennettuna käyttäjien koneille, ja julkaistaan suunnittelijan toimesta muille osapuolille.
Muut osapuolet voivat tilata haluamansa tiedot muilta osapuolilta.

Tiedon jakaminen on hyvin perustavanlaatuinen ongelma rakennusteollisuudessa.
IFC tiedostoformaatti on ollut teollisuuden standardina tiedon jakamiseen, mutta johtuen tietomallinnuksen nopeasta kehityksestä se on jo vanhentunut monen osapuolen tiedonjakoon.
BIM serveri tiedonvaihdon alustana on lupaava askel mutta jos keskitetty tiedostojen hallinta vaihdetaan hajautettuun tiedon hallintaan, se voisi ratkaista monta tiedonvälitys ongelmaa.
Vaikka konsepti ei ole täysin valmis, se tuntuu olevan lupaavin tiedonjakokonsepti tällä hetkellä.
