    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Phosphorescence; Laser Combustion Diagnostics; Non-linearity; Image Intensifier; Two-color Ratio; Lifetime Decay; Precision; Thermographic Phosphors; Temperature measurements; Fysicumarkivet A:2012:Lindén;

    Abstract : Temperature is one of the most fundamental parameters to be measured in many research disciplines. In combustion science, a thorough knowledge of temperature is essential for improving and optimizing combustion processes. READ MORE

  5. 3. Optimised performance of industrial high resolution computerised tomography

    Author : Måns Mångård; Joseph N. Gray; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The purpose of non-descructive enluation (NDE) is to acquire knowledge of the investigated sample. Digital x-ray imaging techniques such as radiography or computerised tomography (CI) produce images of the interior of a sample. The obtained image quality determines the possibility of detecting sample, ·elated features, e.g. READ MORE

  6. 4. The Auroral Large Imaging System : design, operation and scientific results

    Author : Urban Brändström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Aurora; Artificial airglow; HF-pump enhanced airglow; Multistation measurements; Polar Stratospheric clouds; Radio-Induced optical emissions; Spectroscopic imaging observations; Tomography; Rymd- och plasmafysik; Space physics; Rymdfysik; rymdfysik; Space Physics;

    Abstract : The Auroral Large Imaging System (ALIS) was proposed in 1989 by Åke Steen as a joint Scandinavian ground-based nework of automated auroral imaging stations. The primary scientic objective was in the field of auroral physics, but it was soon realised that ALIS could be used in other fields, for example, studies of Polar Stratospheric Clouds (PSC), meteors, as well as other atmospheric phenomena.
