  2. 1. Force Budget Analysis of Glacier Flow : Ice Dynamical Studies on Storglaciären, Sweden, and Ice Flow Investigations of Outlet Glaciers in Dronning Maud Land, Antarctica

    Author : Jim Hedfors; Veijo Pohjola; Else Kolstrup; Niels Reeh; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; force budget; ice flux; ice dynamics; mass balance; strain heating; climate change; Storglaciären; Dronning Maud Land; Antarctica; Naturgeografi och sedimentologi; Physical geography; Naturgeografi;

    Abstract : This thesis contributes to the understanding of glacier response to climate change by ice dynamical studies on Storglaciären, Sweden, and Bonnevie-Svendsenbreen, Kibergbreen and Plogbreen in Dronning Maud Land, Antarctica. Ice surface velocities, ice geometry and temperature information is fed through a force budget model to calculate ice mass outflux of these glacial systems via three-dimensional stress distributions for a flux-gate.

  4. 2. Cost-optimality approach for prioritisation of buildings envelope energy renovation : A techno-economic perspective

    Author : Farshid Bonakdar; Angela Sasic Kalagasidis; Keith Jones; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Building renovation; Energy efficiency; Cost-optimality; costeffectiveness; Building envelope; Residential buildings; Building energy simulation; Brute-force algorithm; Sustainable Built Environment; Hållbar byggd miljö;

    Abstract : The existing residential buildings in the European countries are rather old and often fail to meet the current energy performance criteria. In Sweden, about 45% of the existing residential buildings have been constructed before 1960. READ MORE

    Abstract : Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to 200 - 300 GHz. READ MORE

  6. 4. Making a living in the world of tourism : Livelihoods in backpacker tourism in urban Indonesia

    Author : Erika Sörensson; Dieter Müller; Aina Tollefsen; Michael Haldrup Pedersen; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tourism geography; low-budget tourism; tourism work; backpackers; gender; development geography; livelihood; qualitative research; Indonesia; Southeast Asia.; Human geography; Kulturgeografi;

    Abstract : In many ‘Third World’ societies tourism is seen as a force for economic development and socie-tal change. Employment in tourism has increased, new destinations have been drawn into tour-ism circuits, and many ‘Third World’ governments have adopted ‘pro-poor’ tourism policies as part of their poverty reduction strategies.

  7. 5. Epitaxy and characterization of SiGeC layers grown by reduced pressure chemical vapor deposition

    Author : Julius Hållstedt; KTH; []
    Keywords : Silicon germanium carbon SiGeC ; Epitaxy; Chemical vapor deposition CVD ; Loading effect; High resolution x-ray diffraction HRXRD ; Hall measurements; Atomic force microscopy AFM .;

    Abstract : Heteroepitaxial SiGeC layers have attracted immenseattention as a material for high frequency devices duringrecent years. The unique properties of integrating carbon inSiGe are the additional freedom for strain and bandgapengineering as well as allowing more aggressive device designdue to the potential for increased thermal budget duringprocessing.
