  1. 21. On Invertibility of the Radon Transform and Compressive Sensing

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

    Sammanfattning : 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. LÄS MER

  3. 22. Beyond Going Global : Essays on business development of International New Ventures past early internationalization

    Författare :Jan Abrahamsson; Vladimir Vanyushyn; Håkan Boter; Maria Bengtsson; Svante Andersson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International New Ventures; business models; business model innovation; Sweden; business development; international entrepreneurship; internationalization; dynamic capabilities;

    Sammanfattning : The notion of International New Ventures, or INVs, emerged in academia in the early-to-mid 1990s and generally refers to entrepreneurial firms that tend to internationalize very early in their life-cycle, and whose expansion into foreign markets occurs much more quickly than predicted by earlier theories of the incremental internationalization process. Previous literature proposes effective networking with market partners and, more recently, internationally viable business model among key distinguishing features of INVs that allow for such early and rapid entry into international markets.

  5. 24. Evaluation of Biomarker Responses in Fish : with Special Emphasis on Gill EROD Activity

    Författare :Carin Andersson; Jan Örberg; Björn Brunström; Lars Förlin; Uppsala universitet; []
    Nyckelord :Biology; three-spined stickleback; biomarker; EROD; ethynylestradiol; gill; vitellogenin; spiggin; CYP1A inducers; humic substances; sperm quality; biomonitoring; Biologi;

    Sammanfattning : Many chemicals present in the aquatic environment can interfere with physiological functions in fish. Exposure to chemicals can be revealed by the use of biomarkers. Induction of 7-ethoxyresorufin O-deethylase (EROD) activity is a commonly used biomarker for exposure to CYP1A inducers such as dioxins and polyaromatic hyrdrocarbons. LÄS MER

  7. 25. Fusing Domain Knowledge with Data : Applications in Bioinformatics

    Författare :Claes Andersson; Jan Komorowski; Mats Gustafsson; Yves Moreau; Uppsala universitet; []
    Nyckelord :Bioinformatics; cell cycle; cancer chemotherapy; predictive tests; performance estimation; bioinformatics; Bioinformatik;

    Sammanfattning : Massively parallel measurement techniques can be used for generating hypotheses about the molecular underpinnings of a biological systems. This thesis investigates how domain knowledge can be fused to data from different sources in order to generate more sophisticated hypotheses and improved analyses. LÄS MER
