This submission is devoted to optimization of networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic since limited link availability is a fundamental feature in wireless networks and yet majority of work in survivable network design is restricted to the total single link failures. We assume a given finite set of network stat
Many governmental actors have an operative responsibility in times of emergency. For this task they are becoming more and more dependent on IT systems. First interviews with some emergency managers show that traditional emergency management and risk analysis not always manages to capture this critical dependency. The exact dependence on IT systems in a crisis is often hard to predict, and
Three different biological extremes of irradiation of living organisms, both human and animal, have been investigated and are presented in this thesis. Central to the thesis is the concept of bystander effects of ionizing radiation, i.e. biological responses in a cell that are not caused by that cell receiving a direct hit by ionizing radiation but by the fact that a neighbouring cell has been hit

The study investigates the social interaction between students with a special focus on the possibilities and hindrances for inclusion of the newcomer immigrant students in different groupings at school, an

I separate four types of tensions, belonging to different ‘boxes.’ The first is called cognitive/internal, compri
