  2. 1. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Author : Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Keywords : Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  4. 2. Heterogeneous Technologies for Microfluidic Systems

    Author : Gunjana Sharma; Klas Hjort; Sami Franssila; Uppsala universitet; []
    Keywords : actuator; biosensor; fluidic circuit board; heterogeneous technology; ion track; microfluidic; pump; stainless steel; super-hydrophobic; valve; Viton; TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : In this thesis, conventional and unconventional technologies have been studied and combined in order to make heterogeneous microfluidics with potential advantages, especially in biological applications. Many conventional materials, like silicon, glass, thermoplastic polymers, polyimide and polydimethylsiloxane (PDMS) have been combined in building heterogeneous microfluidic devices or demonstrators.

  5. 3. Alternative Energy Harvesting and Conversion Systems Based on Nanostructured Heterostructures

    Author : Mojtaba Gilzad Kohan; Alberto Vomiero; Andrea Li Bassi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light harvesting; solar supercapacitors; energy conversion; Photovoltaic; energy storage; metal oxide semiconductors; Experimentell fysik; Experimental Physics;

    Abstract : Conversion and storage of the solar radiation into applicable forms of energy, using ubiquitous materials is of central importance that quests several disciplinary fields in both applied technology and fundamental science. Harnessing the solar energy received by the earth has the potential to replace the current sources of energy and it is imperative for sustainable development. READ MORE

  6. 4. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments

    Author : Hampus Wikmark; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast lasers; ultrafast optics; attosecond pulses; pump-probe experiments; XUV light; XUV focusing; wavefront sensing; XUV optics; X-ray optics; Fysicumarkivet A:2019:Wikmark; ultrasnabba lasrar; attosekundspulser; pump-prob-experiment; XUV-ljus; vågfrontmätningar; XUV-optik; Röntgen-optik;

    Abstract : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. READ MORE

  7. 5. Parametrically pumped superconducting circuits

    Author : Philip Krantz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SQUID; circuit quantum electrodynamics; Josephson junction; Superconducting circuits; resonators; parametric oscillators; quantum bit; pumpistor; quantum information;

    Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).
