Lab Scale Simulation of a Leak in a Landfill Cover

Many Swedish landfills are currently applied with a final cover. To minimise costs and the use of natural resources, waste materials can be a suitable substitute in landfill covers. Depending on the wastes’ contents, their mobility and in which layer of the final cover they are used, they could potentially contribute to the emission potential of the landfill. In this study the impact on landfill l

Hazard Analysis of Collision Avoidance System using STPA

As our society becomes more and more dependent on IT systems, failures of these systems can harm more and more people and organizations both public and private. Diligently performing risk and hazard analysis helps to minimize the societal harms of IT system failures. In this paper we present experiences gained by applying the System Theoretic Process Analysis (STPA) method for hazard analysis on a

Toolkit for awareness in universal design

In an attempt to make universal design an integral part of industrial design in general, an experiment was implemented early during the industrial design education. The aim of the experiment was to increase the awareness of the students regarding the fact that products may at the same time be attractive and well-functioning for a broad range of users. Five categories of everyday products were incl

Analysis of Velocity Encoded Images --- With Applications in Cardiac MRI

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

Radiation dose optimization in CT planning of corrective scoliosis surgery. A phantom study.

The aim of the study was to explore the possibility of obtaining a helical CT scan of a long segment of vertebral column, optimally reduce the radiation dose, compare the radiation dose of the low dose helical CT with that of some of the CT protocols used in clinical practice and finally assess the impact of such a dose reduction on the image quality. A chest phantom was examined with a 16-slice C
