  2. 1. Radon in natural waters : Analytical Methods; Correlation to Environmental Parameters; Radiation Dose Estimation; and GIS Applications

    Author : Isam M. Musa Salih; Eva Lund; Håkan B.L. Pettersson; Christer Samuelsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radon analysis; radiation effects; Water chemistry; Water pollution; radioactive analysis; Radiological physics; Radiofysik;

    Abstract : Investigations of radon in natural water and its relation to physical and chemical parameters are outlined in this thesis. In particular, a method for measuring 222Rn in water at low concentrations (~20 mBq. READ MORE

  4. 2. On Invertibility of the Radon Transform and Compressive Sensing

    Author : Joel Andersson; Jan-Olov Strömberg; Mikko Salo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radon transform; invertibility; compressive sensing; stability estimates; Mathematics; Matematik;

    Abstract : This thesis contains three articles. The first two concern inversion andlocal injectivity of the weighted Radon transform in the plane. The thirdpaper concerns two of the key results from compressive sensing.In Paper A we prove an identity involving three singular double integrals. READ MORE

  5. 3. The Rise of Luxury Brands Online : A study of how a sense of luxury brand is created in an online environment

    Author : Anita Radón; Per Olof Berg; Miriam Salzer-Mörling; Micael Dahlén; Lars Strannegård; Stockholms universitet; []

    Abstract : Luxury brands have only recently tapped into the online market in an attempt to increase revenues and expand their businesses. This leap onto the online world has resulted in several new challenges, including the luxury brand paradox. READ MORE

  6. 4. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Author : Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    Abstract : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. READ MORE

  7. 5. On parabolic equations of Kolmogorov-Fokker-Planck type

    Author : Malte Litsgård; Kaj Nyström; Ugo Gianazza; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; degenerate parabolic; ultraparabolic; Lipschitz domain; Dirichlet problem; boundary behaviour; parabolic measure.; Mathematics; Matematik;

    Abstract : In this thesis solutions to Kolmogorov-Fokker-Planck type equations are studied. It consists of a comprehensive summary and four scientific articles.In the first article a potential theory for certain strongly degenerate parabolic operators in unbounded domains of Lipschitz type is developed.
