The thesis addresses the nature of causation. It is argued that causation exists and is as local as its causes and effects. As a consequence, the position advocated is contrary to the as yet prevailing view that no 'causal tie' between cause and effect exists. Moreover, it is suggested that this tie can be perceived. The essay attempts to elucidate the nature of causes, effects, and causal mechani
The prelude to this thesis is provided by the dramatic scenes that took place in Ådalen. During a demonstration, four men and one young woman were shot to death and five others injured by military troops ordered to Lunde harbour. Inspired by a number of other researchers (Koselleck, Samuel, Somers, Stråth, Södring, Jensen and Burke, to name a few), my investigation has analysed how the story of th
Explores elderly and disabled people's travel information requirements when planning a journey by public transport and discusses the potential of information to improve access to the public transport system. Quesionnaire study in order to validate an earlier focus-group interview study about elderly and disabled people's travel information requirements. Results show a need for travel information t
The research underlaying this thesis involves synthesis and characterization of well-defined anionic graft copolymers carrying poly(ethylene oxide) (PEO) side-chains. Two different grafting techniques were used. Backbone polymers were prepared through radical terpolymerization of maleic anhydride, styrene and an additional comonomer. Poly(ethylene oxide) monomethyl ether (MPEO) were grafted onto
This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. The observer based sensorless drive system has superior dynamic performance compared to a system with an open loop frequency in
Hur såg det svenska stödet ut för Norges rätt att lämna unionen 1905.
Sweden is a country that offers a home for thousands of immigrants each year. The year of 2009 Sweden broke its record; the country had never before accepted as many immigrants as it did that year. One can imagine that a country with a high number of immigrants is also highly integrated and provides work for the majority of these newly arrived members of the population - but in Sweden this is not
