  2. 1. Radio emission from supernovae

    Author : Esha Kundu; Peter Lundqvist; Claes Fransson; Stephen Reynolds; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernovae; radio emission; hydrodynamical simulation; Astronomy; astronomi;

    Abstract : This thesis presents the modeling of radio and X-ray emissions from supernova (SN) shock fronts and hydrodynamical simulations of SN-circumstellar medium (CSM) interaction. The interaction of SN ejecta with the CSM drives a strong shock wave into the CSM. READ MORE

  4. 2. On Performance of Digital Radio Receiver in Non-Gaussian Interference

    Author : Kia Wiklundh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bandwidth conversion; performance estimation; APD; interference; minimum shift keying; man-made noise; Gaussian approximation; measurement; emission requirements; non-Gaussian interference; micro-wave oven; MSK; amplitude probability distribution; emission;

    Abstract : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. READ MORE

  5. 3. Modeling of Radio Emission from Supernovae : Application to Type Ia

    Author : Esha Kundu; Peter Lundqvist; Claes Fransson; Talvikki Hovatta; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supernova; Circumstellar interaction; Radio emission; Astronomy; astronomi;

    Abstract : The interaction of supernova (SN) ejecta with the circumstellar medium (CSM) drives a strong shock wave into the CSM. These shocks are ideal places where effective particle acceleration and magnetic field amplification can take place. READ MORE

  6. 4. Optical remote sensing of industrial gas emission fluxes

    Author : John Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical remote sensing; DOAS; gas emission; absorption spectroscopy; VOC; flux measurement; solar occultation; FTIR; formaldehyde;

    Abstract : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have repeatedly shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.
