A significant part of IS systems implemented today introduce a mandatory use environment for their users, where daily tasks and responsibilities are dependent on or even impossible without the use of a specific system. This paper focuses on examining the relevance, importance and potential effects of user satisfaction in these kinds of environments, with the purpose of contributing to this previou
The purpose of this article is to present and discuss the development of a system for assessing and improving healthcare organisations. The system components comprise (1) a framework or model for assessing, measuring, diagnosing and improving healthcare organisations, (2) a simple methodology for data collection, data analysis and prioritising improvement areas and (3) an index named ILL (innovati
We present a novel visibility algorithm for rendering motion blur with per-pixel anti-aliasing. Our algorithm uses a number of line samples over a rectangular group of pixels, and together with the time dimension, a two-dimensional spatio-temporal visibility problem needs to be solved per line sample. In a coarse culling step, our algorithm first uses a bounding volume hierarchy to rapidly remove
The purpose of this thesis is to investigate the Swedish stock market’s reaction of asset sale announcements and to see how the stated use of proceeds impacts the announcement effect. To fulfill the purpose the following research questions are asked: Is there an announcement effect associated with asset sales in general? Is the announcement effect, if any, dependent on the stated use of proceeds?
Kan man kombinera Magnetisk Resonanstomografi, mer k ̈ant som MRI, Magnetic Resonance Imaging, med geometrioptimering av fl ̈odessimuleringar f ̈or att f ̊a fram mer detaljrika bilder av blodfl ̈odet? I denna studiehar vi arbetat med att vidareutveckla ett verktyg f ̈or att ̈oka uppl ̈osningen p ̊a tredimensionella bilder av blodk ̈arl i kroppen. Ett syfte med den h ̈ar tekniken ̈ar att ge l ̈akar4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). This combines lower resolution 4D-flow scans with CFD simulations to improve resolution and reduce scan times. Previous work has focused on inlet and outlet
Vår hemgalax vintergatan är inte lika platt som ofta är trott. Dess form är mycket likt en disk där mitten är tätt fylld med stjärnor och antalet stjärnor avtar desto längre bort från mitten man kommer. Sen 1950-talet har vi också vetat att två motsatta ändar i disken är böjda åt olika håll medans mitten av disken är relativt platt. Senare forskning har även visat på att många andra galaxer är böjContext: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. Aims: We use a full 6-dimensional phase space sample of stars from Gaia DR3 to study the kinematic signature of the Milky Way warp as a function of position i
Det huvudsakliga syftet med detta arbete var att simulera tredimensionella flödesmönster i tankar för lagring av vatten. De praktiska avsikter med simuleringarna var att identifiera vattenkvalitetsproblem relaterade till bristande vattenutbyte. De vattenmagasin som reservoarer vid Norra Ugglarp i Skåne utgör undersöktes i en särskild fallstudie. I denna avhandling har den öppna CFD källkoden OpenFThe main purpose of this thesis was to simulate the three-dimensional flow patterns in tanks for water storage. The practical intentions of the simulations were to identify water-quality problems related to insufficient water exchange. The water storage reservoirs at Norra Ugglarp in South Sweden were investigated as a special case study. In this thesis, the open source CFD software OpenFoam was c
Trait spectra have been used in various branches of ecology to explain and predict patterns of species distributions. Several categorical and continuous traits have been proposed as relevant for ectomycorrhizal fungi, but a spectrum that unifies co-varying traits remains to be established and tested. Here, we propose a nitrogen acquisition and carbon use trait spectrum for ectomycorrhizal fungi in
We develop a framework for categorization in games, applicable both to multistagegames of complete information and static games of incomplete information.Players use categories to form coarse beliefs about their opponents’behavior. Players best-respond given these beliefs, as in analogy-based expectationsequilibria. Categories are related to strategies via the requirementsthat categories contain a
