2. Three Phase Controlled Fault Interruption Using High Voltage SF6 Circuit Breakers
Sammanfattning : A method is presented for implementing controlled fault interruption,using high voltage, SF6 circuit breakers on three phase high voltage powernetworks. The main goal of the method is to synchronize the opening or tripcommands to each phase of a circuit breaker with respect to target currentzero times so that each phase will interrupt with a preselected arcingtime.

3. Exotic Decays of Vector-Like Quarks and Development of a Test Procedure for the ITk Strip Module at the ATLAS Detector for the HL-LHC
Sammanfattning : The naturalness problem of the Standard Model (SM) challenges our understanding of the origin of mass. Several theories have been proposed to tackle the problem, one of them is the Composite Higgs Model (CHM) where the Higgs boson of the SM is not an elementary scalar but instead a composite object bound at a confinement scale of a TeV.

4. Strategies in the digital printing value system
Sammanfattning : The research objective of this thesis is to identify corporate strategies and strategic decisions in the digital printing business and to analyze how these have evolved due to the introduction of digital printing. This thesis comprises three separate studies, all based on qualitative case methodology. LÄS MER
5. The Holocene Spread of Spruce in Scandinavia
Sammanfattning : The Holocene spread of Picea abies in Scandinavia provides an excellent opportunity for detailed study of the dynamics of tree spread and population expansion. Early- and mid-Holocene macrofossil evidence for the presence of Picea abies in Scandinavia has questioned traditional interpretations of the timing and direction of its spread. LÄS MER
