  1. 1. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

    Författare :Danardono; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.

  3. 2. Image Processing and Analysis Methods for Biomedical Applications

    Författare :Eva Breznik; Robin Strand; Filip Malmberg; Joel Kullberg; Håkan Ahlström; Alejandro Frangi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple comparisons; image segmentation; image retrieval; deep learning; medical image analysis; magnetic resonance imaging; whole-body imaging; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : With new technologies and developments medical images can be acquired more quickly and at a larger scale than ever before. However, increased amount of data induces an overhead in the human labour needed for its inspection and analysis. LÄS MER

  4. 3. On drug use, multiple medication and polypharmacy in a national population

    Författare :Bo Hovstadius; Göran Petersson; Sven Tågerud; Bengt Åstrand; Björn Wettermark; Linnéuniversitetet; []
    Nyckelord :drug use; multiple medication; polypharmacy; register; prevalence; therapeutic intensity; acquisition cost.; NATURAL SCIENCES; NATURVETENSKAP; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : The application of multiple medications has successively increased during a number of years and has thereby increased the potential risks of adverse drug reactions, interactions and non-adherence to drug therapy. This may result in unnecessary health expenditure, directly due to redundant drug sales, and indirectly due to the increased hospitalization caused by drug-related problems. LÄS MER

  5. 4. Coding for multiple-access and fading channels

    Författare :Leif Wilhelmsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Gilbert-Elliott channel model; Imperfect interleaving; Fading; Error correcting codes; Pre-coding; Channel capacity; Direct-sequence code-division multiple-access DS-CDMA ; Frequency-hopped code-division multiple-access FH-CDMA ; computer technology; Data- och systemvetenskap; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : This thesis treats some information-theoretical and coding aspects of communication over multiple-access and fading channels. It consists of a general introduction and seven papers. In code-division multiple-access (CDMA) communication, many users have access to the channel simultaneously. LÄS MER

  7. 5. Multiple-trait multiple country genetic evaluation of fertility traits in dairy cattle

    Författare :Mohammad A. Nilforooshan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Female fertility is one of the most economically important traits for the dairy cattle industry. Because of a few decades of selection mainly for higher milk production, many dairy farms around the world suffer from the consequences of female fertility loss. LÄS MER
