The topic of the thesis is the analysis of velocity encoded medical images, acquired using magnetic resonance imaging or other means. The application in mind is to use such data to determine the motion and deformation of the human heart, which is of clinical and physiological interest. As the velocity measurements are noisy and degraded, an important issue is the regularization of the measurements
This paper treats the problem of calculating the macroscopic effective properties of dielectric mixtures where both the inclusions and the background medium can be anisotropic. For this homogenization process, the Maxwell Garnett -type approach is used where the inclusions are assumed to be spherical and embedded in a homogeneous background medium. The anisotropy of the background medium has to be

In schools the temperature of the indoor air is one of the most important factors in terms of the indoor climate. The resulting indoor air temperature is depending on many factors; the temperature of the supply air being one of the more significant one. One fan-assisted natural ventilation system includes a supply air system where the outdoor air should be passively heated respectively cooled when
At the first Nordic meeting for linguists with a research interest in reading and writing, held in Løgumkloster, Denmark, in 1987, we reported on a longitudinal study we had just started. The aim of the study was to find out which kind of linguistic disabilities are the most damaging for the development of reading and writing (Magnusson & Nauclér 1990 a, b). When reading is looked upon as a li
The aim of the study was to explore Swedish classrooms and to identify creativity related moments occurring in ordinary classes and discuss these with teachers and students. The moments were individual actions, interactions between classroom participants or creative ideas/products arising in the classroom (by teacher or student) that were deemed to be either associated with creativity in a positiv
Purpose of this paper: This paper proposes a framework for identifying potential risk and gain sharing challenges related to implementing collaborative change initiatives in supply chains, and uses the framework to explore risk and gain sharing in implementing radio frequency identification (RFID) technology.
Design/methodology/approach: The empirical investigation, based on case study researc
