  2. 1. Radio Resource Allocation and Utilization in Multiple Radio Access Networks

    Author : Georgios Koudouridis; Gunnar Karlsson; Frank H. P. Fitzek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Meeting in a sustainable way the demands of an unprecedented explosive growth in the number of connected devices and mobile data traffic, next-generation mobile networks are expected to make flexible use of spectrum and provide higher capacity by a denser deployment of radio access network infrastructure. In addition, the allocation and the utilisation of radio access resources should improve spectrum usage efficiency and keep energy consumption low, implying the capability to effectively exploit the denser deployment of radio accesses and the co-existence of radio accesses belonging to one or multiple radio access technologies.

  5. 3. Transformation of iron constituents during early diagenesis : in situ studies of a Baltic Sea sediment-water interface

    Author : C. H. Magnus Lindström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of the present study was to elucidate the mechanisms and kinetics of the transformation of iron constituents at the sediment-water interface and their interaction with other element cycles during early diagenesis, with emphasis on their relations with oxygen, phosphorus and sulphur. The investigation was carried out in situ at 10 m water depth on a nearshore Baltic Sea soft bottom sediment. READ MORE

  6. 4. Index theory in geometry and physics

    Author : Magnus C H T Goffeng; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

    Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

  7. 5. Melt flow and surface stability effects on polymer flammability : A study on polystyrene, flexible polyurethane foam and polyolefin composites

    Author : Roland H. Krämer; Ulf W. Gedde; Norman C. Billingham; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Melt; flow; dripping; collapse; combustion; pool fire; feed‐back; gasification; heat release; flammability; nanocomposites; molar mass; intumescence; polyurethane; Polymer chemistry; Polymerkemi;

    Abstract : Our ability to accurately determine the flammability properties of polymers is hampered bythe erratic effects of deformation and liquid flow that occur during polymer combustion.This study aims to improve the understanding of such effects at several levels: The often obvious impact of melt flow on standardized flammability test methods forelectrical appliances is described to identify the need and to motivate others to worktowards an improved material characterization.
