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

This thesis is about the relationship between the legal system and the ways firms organize their economic activities. When firms apply new business models and establishing new forms of relationships, as e.g. in logistics, the law must "keep up" and evolve with them. The law is supposed to provide legal instruments to be used in practical business rendering reactions to unsound business. Without le

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

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

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

The aim was to explore health in relation to the home as experienced by very old, single-living Swedish people. Applying a grounded theory approach, 40 men and women aged 80-89 were interviewed in their own homes. Data analysis revealed the main theme, "The home is the hub of health", comprising two categories, "The home as support for health", and "Having an inner driving force to maintain health

Energy security has gained increasing prominence on the EU political agenda, but is often framed narrowly, in terms of import dependency or security of supply. In this paper we screen and scope out a more comprehensive suite of energy security aspects to be considered when assessing low-carbon energy scenarios and apply it using the EU Energy Roadmap as an example. Availability and affordability i

The cross section sigma = (8+/-4) x 10(-15) cm(2) was determined for the Rb(7S) + Rb(5S) --> Rb(SD)+ Rb(5S) excitation energy transfer process, and the quenching cross section sigma(q) = (2 +/- 1) x 10(-14) cm(2) for the Rb(5D) state in collisions with ground state Rb atoms. Applying rubidium quasimolecular asymptotic potential curves at relatively large internuclear distances, a qualitative inter
