Calculations are reported of the nonlinear screening of a proton in an electron gas of densities corresponding to rs=1-6. Results for charge densities and total energies are presented from self-consistent Kohn-Sham ground-state calculations. The results differ markedly from the case of linear screening, particularly at low densities. The occurrence of a bound state around the proton for rs>1.9 ind
The support for the fight against ‘human trafficking’ has evolved rapidly and comprehensively. There has been, however, no overarching critical evaluation of the efforts to make ‘human trafficking’ a focus of international law. The study addresses this gap and questions the usefulness of the international law definition of human trafficking and the legal framework built around this definition. It
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
