  2. 21. Algorithms and Representations for Personalised Information Access

    Author : Rickard Cöster; Lars Asker; Haym Hirsh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Personalised information access systems use historical feedback data, such as implicit and explicit ratings for textual documents and other items, to better locate the right or relevant information for individual users.Three topics in personalised information access are addressed: learning from relevance feedback and document categorisation by the use of concept-based text representations, the need for scalable and accurate algorithms for collaborative filtering, and the integration of textual and collaborative information access.

  4. 22. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Author : Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. READ MORE

  5. 23. Methods and Algorithms for Data-Intensive Computing : Streams, Graphs, and Geo-Distribution

    Author : Hooman Peiro Sajjad; Vladimir Vlassov; Keijo Heljanko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stream processing; geo-distributed infrastructure; edge computing; streaming graph; dynamic graph; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

    Abstract : Struggling with the volume and velocity of Big Data has attracted lots of interest towards stream processing paradigm, a paradigm in the area of data-intensive computing that provides methods and solutions to process data in motion. Today's Big Data includes geo-distributed data sources. READ MORE

  6. 24. Statistical modelling and analyses of DNA sequence data with applications to metagenomics

    Author : Mariana Buongermino Pereira; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised hidden Markov models; gene abundance data; metagenomics; statistical modelling; bioinformatics; normalisation; DNA sequence data; bioinformatics;

    Abstract : Microorganisms are organised in complex communities and are ubiquitous in all ecosystems, including natural environments and inside the human gut. Metagenomics, which is the direct sequencing of DNA from a sample, enables studying the collective genomes of the organisms that are there present. READ MORE

  7. 25. Fluid Dynamics and Granular Growth in High Shear Wet Granulation

    Author : Anders Darelius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coalescence kernel; Frictional Stress Models; Laser Doppler Anemometry; Population balances; CFD; EFD; High shear granulation; High speed imaging; Multi-dimensional; Multiphase flows;

    Abstract : High shear wet granulation is a key step in the manufacturing of tablets in the pharmaceutical industry. From the pharmaceutical industry’s point of view, there is a desire for predictive quantitative process models to be able to make in-silico process and scale-up simulations, which would shorten and reduce the cost of technology transfer from laboratory scale to manufacturing scale in drug development.
