  1. 1. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Författare :Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

    Sammanfattning : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. LÄS MER

  3. 2. Nuclear structure close to 100Sn

    Författare :Joakim Cederkäll; KTH; []
    Nyckelord :;

    Sammanfattning : The nuclear structure of neutron deficient isotopes in thevicinity of the douhle shell closure at1ooSn has been experimentally investigated by meansof y-spectroscopic meth ods. Experimental information onexcit,ed st,ates in nuclei in the vicinity of1ooSn has been scarce until recently. LÄS MER

  4. 3. Solar Wind Dynamics within The Atmosphere of comet 67P/Churyumov-Gerasimenko

    Författare :Etienne Behar; Hans Nilsson; Thomas E. Cravens; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : In this thesis, we explore the dynamics of the solar wind as it perme-ates and flows through a tenuous cometary atmosphere, with a focuson the interaction observed at comet 67P/Churyumov–Gerasimenko.Seven comets had already been visited by nine different probes when the European spacecraft Rosetta reached comet Churyumov–Gerasimenko in August 2014.

  5. 4. REMAP-γ: A Scalable SIMD VLSI Architecture with Hierarchical Control

    Författare :Lars Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; array signal processing; hierarchical control; SIMD; VLSI architectures; distributed synchronous clocking; embedded supercomputing;

    Sammanfattning : While the clock speed of general purpose (uni-)processors has risen dramatically during recent years, this is not true for SIMD (Single Instruction stream Multiple Data streams) parallel processors. The reason is to be found in the structure of this type of architecture: long-range broadcasting of data, clock and control signals. LÄS MER

  7. 5. Utilities and quality of life in cardiovascular disease : drivers, economic effects and clinical outcomes

    Författare :Jenny Berg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atrial fibrillation and chronic heart failure represent important contributors to cardiovascular disease burden, with high incidence, prevalence and mortality rates. The overall objective of this thesis is to enhance the knowledge on what drives preferences for different health st ates (utilities) in patients with atrial fibrillation and chronic heart failure, and how health-related quality of life and utilities in turn influence clinical and economic outcomes.
