  4. 17. Spectral signature measurements and image processing for geological remote sensing

    Author : Kjell Wester; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturgeografi; Physical Geography;

    Abstract : This work focuses on (i) spectral signatures of rocks and lichens, and on the use of satellite images for (ii) survey mapping of areas dominated by exposed bedrock, (iii) bedrock mapping and mineral prospecting.(i) Laboratory measurements demonstrate that a lichen cover can significantly mask the spectral reflectance of rocks.

  5. 18. Regulating energy performance of residential buildings in cold climate : a study of indicators, criteria, and evaluation methods

    Author : Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy performance; building simulation; cold climate; energy use; indicators; evaluation methods; building regulations; residential buildings; energy measurements; performance gap; energy signature; sustainable development; hållbar utveckling; fysik; Physics;

    Abstract : Building energy performance has been important in Fennoscandia ever since the early vernacular houses, to combat the cold climate. Due to EU directive 2010/31/EU on the energy performance of buildings (EPBD recast), building energy performance has become even more relevant in northern Europe the last decade. READ MORE

  6. 19. Measurement and Control of Attosecond Light Fields

    Author : Erik Mansten; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse characterization; Spectral signature; Two-color generation; Pulse compression; Attosecond pulse trains; High-order harmonics; Pulse shaping; Tunable; Fysicumarkivet A:2009:Mansten;

    Abstract : Attosecond pulses are used to study electron dynamics in atoms and molecules. In this thesis, schemes to control the generation of attosecond pulses and pulse-shaping techniques to compress the pulses are presented. Generation of attosecond pulses requires high intensity, which is reached by focusing a pulsed femtosecond laser. READ MORE

  7. 20. Improved building energy simulations and verifications by regression

    Author : Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Abstract : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.
