  1. 26. Mining of User Profiles in Online Social Networks for Improved Personalized Recommendations

    Författare :Shatha Jaradat; Mihhail Matskin; James Caverlee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : We have focused on influencer-based marketing in online social networks as a source of implicit learning about the preferences of social media users. Those users who use social networks on a daily basis are also the online shoppers who are confronted with huge information overload and a wide variety of online products and brands to choose from.

    Sammanfattning : Vascular diseases are getting more and more common as a result of modern-day lifestyle and the fact that the population is getting older. One of the newest treatments for vascular diseases such as aneurysms and dissections is endovascular repair with endografting. LÄS MER

  5. 29. Digital holography and image processing methods for applications in biophysics

    Författare :Hanqing Zhang; Magnus Andersson; Krister Wiklund; Wählby Carolina; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital holographic microscopy; image processing; image reconstruction; bacterial adhesion; cell morphology; algorithm development; software design; quantitative measurement; microfluidics; multidisciplinary research; signalbehandling; Signal Processing; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Sammanfattning : Understanding dynamic mechanisms, morphology and behavior of bacteria are important to develop new therapeutics to cure diseases. For example, bacterial adhesion mechanisms are prerequisites for initiation of infections and for several bacterial strains this adhesion process is mediated by adhesive surface organelles, also known as fimbriae.
