  2. 1. Improving the understanding of cloud radiative heating

    Author : Erik Johansson; Abhay Devasthale; Michael Tjernström; Annica M. L. Ekman; Robert Pincus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clouds; radiative effects; upper troposphere-lower stratosphere; atmospheric circulation; remote sensing; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Clouds play an essential role in regulating Earth’s radiation budget by reflecting and absorbing energy at different spectra. As they interact with radiation, they can radiatively heat or cool the adjacent atmosphere and the surface. READ MORE

  4. 2. Multi-satellite views on mesospheric microphysics and dynamics

    Author : Lina Broman; Jörg Gumbel; Susanne Benze; Scott Bailey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polar mesospheric clouds; satellite tomography; remote sensing; cloud microphysics; wave dynamics; mesosphere; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Atmospheric gravity waves of different scales and origins strongly modulate the wind field and temperature structure of the higher parts of the atmosphere. Direct and continuous measurements of these processes are particularly complicated in the mesosphere at about 50 to 100 km height due to the remote location of this region. READ MORE

  5. 3. Post-Detonation Afterburning of High Explosives

    Author : Katja Fedina; Strömningsteknik; []
    Keywords : Explosives; Combustion; LES; Finite rate chemistry; Explosives; Combustion; LES; Finite rate chemistry; Height of Burst;

    Abstract : High performance of an explosive compound with respect to afterburning requires sufficient combustible properties of the explosive, and a careful determination of the most appropriate charge positioning to achieve the desired afterburning effect. Understanding the physical processes of post-detonation afterburning and how these are affected by the surroundings, e. READ MORE

  6. 4. Segmentation of forest patches and estimation of canopy cover using 3D information from stereo photogrammetry

    Author : Ann-Helen Granholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an affordable alternative to airborne laser scanner (ALS) data. READ MORE

  7. 5. Flow structures in solid-liquid suspensions in mixing and confined jets

    Author : Matthias Eng; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is an investigation of the influence of solid particles on different liquid flow systems. Large-scale periodic fluctuations such as macro instabilities (MI) and particle cloud dynamics in a mixing vessel and confined jets were studied experimentally and compared to numerical results from CFD simulations.
