We consider a wind power plant of megawatt wind turbines operating in derated mode. When operating in this mode, the wind power plant controller is free to distribute power set-points to the individual turbines, as long as the total power demand is met. In this work, we design a controller that exploits this freedom to reduce the fatigue on the turbines in the wind power plant. We show that the co

The infrastructure for the third generation of mobile telephony, UMTS, is under construction in Sweden. Within three years four operators were to build competing systems to cover 99,98 % of the population. The case of the 3G infrastructure illustrates how sustainability issues are handled in planning and environmental management, with conflicting goals between institutional levels and contradict

Based on an ongoing debate—academic as well as public—regarding the roles of the teacher and the student in education, this thesis explores educational relations within the field of philosophy of education. After critically examining intersubjective approaches to theories of educational relations, I localize anthropocentrism and subject-centrism (teacher/student) as two problematic aspects of the

We have previously shown how it is possible to lower accident risk levels while at the same time increasing traffic flows with the aid of vehicular ad-hoc networks. In this paper, we extend the online traffic accident risk mitigation sys- tem to include link choice. We develop an algorithm that allows vehicles to choose road links that provide the current maximal utility, based on information rece

Mergers of autonomous executive authorities in central government have become increasingly common, in particular in the Nordic countries. As compared to private sector mergers, the role of the principal (the central Government and its ministries) is more obscure in these mergers, this chapter argues. When problems arise in a merger, the ministry can take a step back and shift to a stakeholder posi

An analysis of Peter Dalle's film Yrrol and Daniel Alfredson's film Tic Tac as non-typical Swedish genre films at this time.

We study quantization noise modeling in a low-delay vector predictive transform coder for speech signals. The coder uses a Kalman filter with a backward estimated LPC model of the speech signal combined with an additive noise model of the quantization noise. Computer simulations indicate that modeling of the quantization noise can improve the quality of the decoded speech signal. This is especiall

Birger Sjöbergs fridavisor dateras, utvecklingen inom fridadiktningen klargörs. Fridavisorna analyseras som parodier.Traditionsbakgrunden till parodin söks i folkliga visor, skillingtryck, manskörsång, i breda lager spridda dikter och visor.

Kriminalvård i frihet, frivård, har sina rötter som ett alternativ till fängelse. Men vad är det för något? Är det ett straff? Jag tittar här på straffets karaktäristiska komponenter: tiden, rummet, observationen och pinan utifrån dels Michel Foucaults disciplineringsbeskrivningar och dels intervjuer med dömda, övervakare och handläggare i frivården. Observationen existerar i hög grad, men rummet

Denna bok handlar om hur en stor litterär tradition, den engelska, gestaltats på film. Med nedslag i Tennysons klassiska dikt ”The Charge of the Light Brigade”, Lord Byrons och paret Shelleys förment liderliga leverne, litteraturen som filmatiserad propaganda under det andra världskriget, Dickens’ roman Great Expectations och Shakespeares drama Macbeth besvaras frågor om hur filmen både tillvarata

Since the European conquest of Latin America, mechanisms and justifications for unequal access to and control over natural resources have developed in tandem with racial ideologies and institutions. Conceiving race and racism as sociocultural systems that evolve historically with and through the organization of human-environment relations, this chapter considers cases in which racism supported the

The early Stone Age hunters in southern and central Finland were specialized in game species living in young deciduous forests, such as the European elk, the beaver, and the Arctic hare. Later on, the game was enriched by species associated with pine and mixed oak forests, such as the brown bear, the pine marten, the red squirrel, and the forest reindeer. In Lapland the subsistence of the early hu
