The aim of the present work was to use the displacement information generated from the spatial alignment in order to compute wood shrinkage in the radial and tangential directions in computed tomography (CT) images, and to compare the results with those obtained with computer-aided design software on the same images. To estimate the shrinkage coefficients from tomography images, wood specimens in the green state, equilibrium moisture content 15% and 8% state and oven dry condition were scanned. Specimens were taken from Norway spruce and Scots pine logs. The root-mean-square-error calculations showed acceptable small differences between the two measuring methods, which means that the algorithm is a useful tool for estimating the shrinkage coefficients in radial and tangential direction from CT images. This provides an image processing tool to monitor the dimensional changes during the drying and heat treatment process. 

IT-support at the Lulea University of Technology, Sweden, 14000 students, consisted up to the beginning of 2006 mainly of technical support. The support was described in terms of technology like computer model, amount of CPU, size of core memory, backup descriptions in terms of online storage, frequency time between backups etc. The quality of service was orally said to be ”as soon as possible” which implied that an incident would be “looked upon the next day and the ambition was to fix it in a week”. The security problems were immense – e.g. some webservers were restarted once a day due to hacking. To that the IT-service 2005 got a drop in funding with 23 % and an order to maintain service level. Although the IT-service cut out almost everything from support contracts to education of staff it was almost on its knees. The familiar place where most people had their own rooms had to be replaced with an office landscape. The formal organisation was changed. The informal structure was beaten and the mood was low. With that in background we also had to implement the new IT-strategy vision. The challenge was now to implement a system and even more important – the attitude - that delivers ”service not technology”. We are still on the route to do so. Slowly are we changing the thinking from ”we need more people” to ”how can we deliver in another way”. But still the arguments often heard are ”IT-service must forbid the users to use that specific application” or “they should only be allowed to use one type of application and one single version” etc. How we attacked these issues with SLA’s, agreements, negotiations, introducing “computer power”, guaranties, consolidation, change of billing system, and how we at the same time found the lack of internal communication to be one of the main problems in this development – this and some errors will shortly be described by the officer for customer relations. For in the end - we did deliver - although we didn’t cut 23 %– we cut 15% - and we did implement the alfa version of our Service Level Agreements.

This second paper will present what happened with IT-delivery after centralization during an economically difficult period in the university’s history. It will tell how the late introduced ITgovernment (The Demanding Board of IT) worked and made a change in both the internal discussion climate and how the attitudes changed from blaming to collaboration. It will present some of the good statements taken. The paper will then shortly discuss the conflict between a fully paid quality dependent service delivery and the public service’s way of looking at costs, payments and management. It will present some updated SLAs (Service Level Agreements). But also how we removed all internal invoices by replacing them with a direct transfer system, reducing internal handling costs from 40 to near 0 Euro per invoice and how we solved the invoice information. Of course it will resume some of our new mistakes. In the end this paper will question if a detailed IT-price list leads to sub optimization. The paper is a free standing follow-up from a paper published as a poster at Eunis Conference 2006 in Grenoble with the title “From technical specification to service delivery”. That described how we reduced IT-costs with 15% (goal 23%), introduced ITIL (Information Technology Infrastructure Library), described many standard services in SLDs (a sort of Service Level Agreements) and introduced rented computers in order to standardize the computer environment. It also told how we handled fines and penalties and what mistakes we made during that revolutionary period.Some Headlines: Who we are; IT as a service; The Demanding Board of IT; The conflict; Invoicing removal; Web affirmation

This paper will present an implementation of WBS Services to pre- and post process motion information from a real or synthetic vehicle.
