  1. 11. Towards better practices in detection of wastewater pollution in stormwater sewers and volume estimation of SSO discharges

    Författare :Oleksandr Panasiuk; Sveinung Sægrov; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Separate sewerage systems are designed so that the wastewater and stormwater are carried separately. However, in practice, untreated wastewater discharges to receiving waters are not that rare, impairing the quality of the receiving waters and increasing the risks to public health and aquatic organisms.

  3. 12. Stochastic Models Involving Second Order Lévy Motions

    Författare :Jonas Wallin; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is based on five papers (A-E) treating estimation methods for unbounded densities, random fields generated by Lévy processes, behavior of Lévy processes at level crossings, and a Markov random field mixtures of multivariate Gaussian fields. In Paper A we propose an estimator of the location parameter for a density that is unbounded at the mode. LÄS MER

  4. 13. Heuristic optimization of the p-median problem and population re-distribution

    Författare :Mengjie Han; Kenneth Carling; Johan Håkansson; Pascal Rebreyend; David Philip McArthur; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : This thesis contributes to the heuristic optimization of the p-median problem and Swedish population redistribution.  The p-median model is the most representative model in the location analysis. LÄS MER

  5. 14. Exploiting Sparse Structures in Source Localization and Tracking

    Författare :Maria Juhlin; Matematisk statistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source localization; Cramér-Rao bounds; Convex Optimization;

    Sammanfattning : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. LÄS MER

  7. 15. Synthetic Aperture Radar Signal and Image Processing for Moving Target Indication and Side Lobe Suppression

    Författare :Thomas Sjögren; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; Space time adaptive processing;

    Sammanfattning : The thesis summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. LÄS MER
