   Sammanfattning : Communicating over a wireless channel poses many unique challenges not found in wired communication because of the special characteristics of the wireless channel. The capacity in a wireless network is typically scarce as a result of the limited bandwidth and many distinct phenomenons, like attenuation and interference, that work destructively on the received signals.

   Sammanfattning : The emergence of large-scale Internet services coupled with the evolution of computing technologies such as distributed systems, parallel computing, utility computing, grid, and virtualization has fueled a movement toward a new resource provisioning paradigm called cloud computing. The main appeal of cloud computing lies in its ability to provide a shared pool of infinitely scalable computing resources for cloud services, which can be quickly provisioned and released on-demand with minimal effort.

   Sammanfattning : This dissertation is an ecclesiological study, conducted in the form of a case study that examines worship praxis in six parishes in the diocese of Luleå between 1990 and 2009. The specific research problem of the dissertation is whether the organizational changes that took place in connection with the relational change between Church and State in 2000 are reflected in local worship and in church service related decisions in diocese and parishes, and how the concrete relationship between worship praxis and regulations is manifested.
