  1. 6. Elucidation of complex diseases by machine learning

    Författare :Karolina Smolinska Garbulowska; Jan Komorowski; Claes Wadelius; Tuuli Lappalainen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine learning; complex disease; multi-omics; regulatory element; gene regulation; transcription factor motif; networks; rough sets; Bioinformatics; Bioinformatik;

    Sammanfattning : Uncovering the interpretability of models for complex health-related problems is a crucial task that is often neglected in machine learning (ML). The amount of available data makes the problem even more complicated. LÄS MER

  3. 7. A study of contaminated lubricants concerning wear, rheological properties and sample withdrawal

    Författare :Sven Berg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The wear of a machine, whether it is due to fatigue or abrasive wear, will add contaminants, in the form of particulates, to the system in question. Since a total breakdown of the machine can be rather costly, one wants to be able to foresee breakdowns and increase the machine life. LÄS MER

  4. 8. Photo diodes for machine vision : device characteristics and a-Si:H deposition and analysis

    Författare :Annika Rantzer; Marcus Böhm; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : During the last years the area of digital cameras based on CMOS technology has grown rapidly. In CMOS, signal processing circuitry and sensor elements can be combined on the same chip, which has resulted in advanced machine vision chip designs. LÄS MER

  5. 9. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder

    Författare :Muhammad Ahmer; Pär Marklund; Fredrik Sandin; Kim Berglund; Martin Gustafsson; Peter Krajnik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analysis; grinding machines; diagnostics; predictive maintenance; condition monitoring; intelligent fault diagnosis; Maskinelement; Machine Elements;

    Sammanfattning : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. LÄS MER

  7. 10. Rolling bearing lubrication at low temperature

    Författare :Victoria Wikström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Problems connected with rolling bearings at low temperatures are high starting and running friction, concerns about the presence of a lubricating film and the degree of roller slip at low-temperature start-up. Also, questions have been raised whether the high shear stresses in a grease sheared at low temperature could cause thickener degradation. LÄS MER
