  1. 1. Physical activity in the severely obese : studies on measurement and promotion

    Författare :Erik Hemmingsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The amount and quality of evidence on how to effectively promote physical activity (PA) is low compared to what is known about the health effects of regular PA, especially in obese individuals. Aim : To evaluate the role of social support to promote walking in severely obese outpatients. LÄS MER

  3. 2. Student-environment fit for students with physical disabilities

    Författare :Helena Hemmingsson; Karolinska Institutet; Karolinska Institutet; sektionen för arbetsterapi Institutionen Neurotec Karolinska Institutet; []
    Nyckelord :Schools; environment; disabled children; adolescents; participation; Schools; environment; disabled children; adolescents; participation.;

    Sammanfattning : The overall aim of the research presented here was to identify and explore aspects of the school environment that influence the participation of students with physical disabilities. The first study examined the reliability and validity of the School Setting Interview (SSI), which is a new assessment still under development. LÄS MER

  5. 4. Power System Oscillations - Detection, Estimation and Control

    Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER

  7. 5. Linear differential operators and their Hutchinson invariant sets

    Författare :Nils Hemmingsson; Boris Shapiro; Per Alexandersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; matematik; Mathematics;

    Sammanfattning : In this licentiate thesis we consider problems related to what we call Hutchinson invariance, which is a form of invariance for sets in the complex plane or the Riemann sphere with respect to the action of special differential operators.In the introductory chapter, we provide a background on Hutchinson invariance, explain how it relates to other problems in dynamical systems and why it is an interesting subject of study.
