  2. 6. The development of resource polymorphism – Effects of diet, predation risk and population dynamical feedbacks

    Author : Jens Andersson; Lennart Persson; André M. De Roos; Umeå universitet; []
    Keywords : body shape; diet; geometric morphometrics; phenotypic plasticity; population dynamics; predation risk; resource polymorphism; size structured populations;

    Abstract : This thesis deals with the evolution of individuals within a species adapted to utilize specific resources, i.e. resource polymorphism. Although a well-known phenomenon, the understanding of the mechanisms behind is not complete. READ MORE

  4. 7. Mobile Network Operators and Cooperation : A Tele-Economic Study of Infrastructure sharing and Mobile Payment Services

    Author : Jan Markendahl; Jens Zander; Per Andersson; Heikki Hämmäinen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication theory; Telekommunikationsteori;

    Abstract : Mobile network operators are currently faced with a number of challenges at the market. The revenues from voice services have decreased the last couple of years. Mobile broadband access services are being adopted and the demand is increasing. The increasing traffic volumes require investments in order to increase the network capacity. READ MORE

  5. 8. MRI based radiotherapy planning and pulse sequence optimization

    Author : Jens Sjölund; Hans Knutsson; Mats Andersson; Michael Felsberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more effective radiotherapy treatments with fewer side effects. READ MORE

  7. 10. Crystallographic Aspects of Protein Phasing at Very Low Resolution

    Author : Klas Andersson; Jens Nyborg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Abstract : A protein crystallographic method for obtaining structure factor phases of low-order reflections is presented. It is based on four observations: 1) The electron density inside proteins is relatively smooth and uniform at low resolution. READ MORE
