   Sammanfattning : Constraint programming (CP) is a technology in which a combinatorial problem is modelled as a conjunction of constraints on variables ranging over given initial domains, and optionally an objective function on the variables. Such a model is given to a general-purpose solver performing systematic search to find constraint-satisfying domain values for the variables, giving an optimal value to the objective function.

   Sammanfattning : In this thesis the properties of proteins and membranes are studied by molecular dynamics simulations. The subject is decomposed into parts addressing free energy calculations in proteins, mechanical inclusion models for lipid bilayers, phase transitions and structural correlations in lipid bilayers and atomistic lipid bilayer models.

5. 14. Holographic descriptions of collective modes in strongly correlated media

   Författare :Marcus Tornsö; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmonics; strongly correlated media; holography; gauge gravity duality; graphene; strong coupling; quasinormal modes;

   Sammanfattning : Solving the puzzle of high temperature superconductivity may be one of the most desired scientific breakthroughs of our time, as access to room temperature superconductivity could revolutionize society as we know it. In this thesis, we strive to increase the theoretical understanding of such matter, by studying the phase above, in temperature, the superconducting phase - the "strange metal". LÄS MER

7. 15. Everyday life amongst the oldest old : descriptions of doings and possession and use of technology

   Författare :Åsa Larsson; Jan-Erik Hagberg; Lena Haglund; Louise Nygård; Linköpings universitet; []
   Nyckelord :Odest old; ageing research; everyday technology; gerontechnology; environmental gerontology; everyday life; ADL; occupational therapy; MEDICINE; MEDICIN;

   Sammanfattning : The general aim of the present thesis is to expand knowledge about the everyday lives of the oldest old (85+) living independently and to improve and deepen the understanding of their doings and possession and use of technology. The everyday lives of the oldest old represent, in many aspects an under-researched area, partly because this age group is seldom included in national surveys regarding living conditions and time use.
