Popular Abstract in Swedish Ekonomiska och miljömässiga problem gör det svårt att bygga ut kraftledningsnätet i samma takt som efterfrågan på elenergi ökar. Ett alternativ är att öka belastningen av befintliga kraftledningar på bekostnad av de säkerhetsmarginaler som finns. En av flera dimensionerande faktorer är risken för otillräckligt dämpade effektpendlingar mellan generatorer i kraftsystemet.Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. A consequence is that power system damping is reduced, leading to a risk of poorly damped power oscillations between the generators. This thesis proposes the

In this paper, survey data from 60 demonstrations in 8 European countries is analyzed, to explore whether social class matters in political protest. Do different types of demonstrations mobilize different groups of employees/workers? And do social class matter for demonstrators’ attitudes about social inequality, welfare privatization and political trust—or do national context and/or the issue of

Management scholars have long separated the study of opportunity creation and discovery, assuming that the nature of opportunities itself is not affected by information acquisition. Research on judgment and decision-making challenges this assumption, confirming that we judge the nature of opportunities in large part by the way we acquire information about it. Management theorists have yet to diges

This thesis is about the flight of vertebrates and the studies of different modes of flight. Flight has always fascinated mankind and this fascination gave inspiration for our attempts at flying. Yet there are many different modes of flight among vertebrates and this thesis focuses mainly on the flapping flight of bats and intermittent flight of birds, as well as compares some of the factors conce

122 patients with Alzheimer's disease receiving galantamine in the Swedish Alzheimer Treatment Study were studied with respect to longitudinal change in cognition (MMSE and ADAS-cog) and function (IADL, PSMS and FAST). Particularly the FAST mean change from baseline showed a linear relationship with cognitive mean change and the strength of the relationship increased over time. The IADL scale demo

Almost all realms of Chinese society have been affected by privatization. Education is no exception, although its privatization does not necessarily affect the school system per se. Chinese scholars have usually provided two explanations for privatized schooling in China: 'massification' (educational expansion) and 'pluralization' (diversification). In my research project on private schools in ur
