  1. 21. Studying neutron-induced fission at IGISOL-4 : From neutron source to yield measurements and model comparisons

    Författare :Andrea Mattera; Stephan Pomp; Mattias Lantz; Andreas Solders; Jonathan Wilson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fission yields represent the probability of producing a certain nuclide in a fission event, and are important observables for fission research. For applications, accurate knowledge of the yields is fundamental at all stages of the fuel cycle of nuclear reactors, e.g., for reactivity calculations, or to estimate (spent) fuel inventory.

  3. 22. On Perceived Exertion and its Measurement

    Författare :Elisabet Borg; Birgitta Berglund; Ana Garriga-Trillo; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perceptual scaling; psychophysics; Category-Ratio scale; perceived exertion; interindividual comparisons; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : The general aim of the thesis is to answer questions on general and differential aspects of perceived exertion and on the measurement of its intensity variation. Overall perceived exertion is commonly treated as a unidemensional construct. This thesis also explores its multidimensional character. Four empirical studies are summarized (Study I-IV). LÄS MER

  4. 23. On Aging, Behavior and the Role of PA28αβ in Protein Homeostasis

    Författare :Julia Adelöf; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregation prevention; Aging; Animal ethics; Cataract; Exploratory behavior; F2 hybrid mice; Healthy aging; Learning and memory; PA28αβ; Proteasome capacity; Sex comparisons; Water-based behavioral tests;

    Sammanfattning : As life expectancy increases, understanding challenges related to the processes of aging are more relevant than ever. Common age-related diseases progress as consequences of accumulative protein damage and protein aggregates. LÄS MER

  5. 24. Towards a Road Safety Development Index (RSDI) : Development of an International Index to Measure Road Safety Performance

    Författare :Ghazwan Al Haji; Kenneth Asp; Linköpings universitet; []
    Nyckelord :Technology; Road safety; RSDI; ASEAN; international comparisons; Human Development; Index; ranking; principal components; composite indicators; macro-performance indicators; macro-models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Aim. This study suggests a set of methodologies to combine different indicators of road safety into a single index. The RSDI is a simple and quick composite index, which may become a significant measurement in comparing, ranking and determining road safety levels in different countries and regions worldwide.

  7. 25. 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
