  2. 21. A study of heat transfer from cylinders in turbulent flows by using thermochromic liquid crystals

    Author : Roland Wiberg; KTH; []
    Keywords : Fluid mechanics; convection heat transfer;

    Abstract : In gas quenching, metal parts are rapidly cooled from hightemperatures, and the convection heat transfer coefficientdistributions are of importance for the hardness and thedistortion (the shape nonuniformities) of the quenched parts.Thermochromic liquid crystals (TLC) and a thin foil techniques,were investi- gated and used for studies of a circular cylinderin axial flows, affected and not affected by upstream owmodifying inserts.

  4. 22. Lyman-alpha radiative transfer in Star-forming galaxies

    Author : Florent Duval; Göran Östlin; Marc Dijkstra; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; astronomi;

    Abstract : This thesis focuses on the intrinsically strongest spectral signature of star-forming galaxies: the Lyman alpha recombination line of the hydrogen atom (hereafter Lya). Located at the wavelength of 1215. READ MORE

  5. 23. Thermal modelling and evaluation of borehole heat transfer

    Author : Saqib Javed; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pump; fluid temperature; borehole; short-term; thermal response test; groundwater-filled; optimization; load aggregation; simulation; recovery; step-response; long-term; ground heat exchanger; times; design; ground-coupled;

    Abstract : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. READ MORE

  6. 24. Estimation of line properties in the copper access network

    Author : Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. READ MORE

  7. 25. Modeling the Zeeman Effect in Planetary Atmospheric Radiative Transfer

    Author : Richard Larsson; Bernd Funke; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric Science; Rymdteknik; Space Technology;

    Abstract : There are special effects in spectroscopy that must be considered in order to fullyexplain how molecular oxygen interacts with radiation in planetary atmospheres.One of these, the Zeeman effect, is described in this thesis. READ MORE
