  1. 1. Prop profiles of compatible Poisson and Nijenhuis structures

    Författare :Henrik Strohmayer; Sergei Merkulov; Gilles Halbout; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Koszul duality; resolutions; props; operads; compatible structures; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : A prop profile of a differential geometric structure is a minimal resolution of an algebraic prop such that representations of this resolution are in one-to-one correspondence with structures of the given type. We begin this thesis with a detailed account of the algebraic tools necessary to construct prop profiles; we treat operads and props, and resolutions of these through Koszul duality. LÄS MER

  2. 2. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Författare :Jenny Lindberg; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Sammanfattning : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. LÄS MER

  3. 3. Towards an on-chip power supply: Integration of micro energy harvesting and storage techniques for wireless sensor networks

    Författare :Agin Vyas; Chalmers University of Technology; []
    Nyckelord :Microsuperca- pacitor; On-chip power supply.; Piezoelectric energy harvester; CMOS compatible; MEMS;

    Sammanfattning : The lifetime of a power supply in a sensor node of a wireless sensor network is the decisive factor in the longevity of the system. Traditional Li-ion batteries cannot fulfill the demands of sensor networks that require a long operational duration. LÄS MER

  4. 4. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Författare :Gösta Lilius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

  5. 5. Mathematical Models and Algorithms for Wireless Network Design and Optimization

    Författare :Yuan Li; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; max-min flow; directional antenna; optimization; integer programming; cellular backhaul network design; delay minimization; SINR; compatible set;

    Sammanfattning : Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions.
