  1. 1. Physical activity in patients with heart failure : motivations, self-efficacy and the potential of exergaming

    Författare :Leonie Klompstra; Tiny Jaarsma; Anna Strömberg; Felicity Astin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; physical activity; exercise; motivation; self-efficacy; exergame; Hartfalen; lichamelijke activiteit; bewegen; motivatie; self-efficacy; exergame;

    Sammanfattning : Background: Adherence to recommendations for physical activity is low in patients with heart failure (HF). It is essential to explore to what extent and why patients with HF are physically active. LÄS MER

  3. 2. Tycho-Gaia and beyond: Combining data for precision astrometry

    Författare :Daniel Michalik; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proper motions; parallaxes; positions; map of the Milky Way; joint solution; Gaia; detection of exo-planets; astrometry; catalogue combination; Tycho-Gaia Astrometric Solution; Hundred Thousand Proper Motion project; Fysicumarkivet A:2015:Michalik;

    Sammanfattning : Astrometry aims at producing a three-dimensional map of positions and motions of stars and other celestial bodies in a consistent coordinate system covering the whole sky. This is best done from space, which provides a way of scanning the entire sky by a single instrument in a thermally stable environment. LÄS MER

  4. 3. Characterization and analysis of the astrometric errors in the global astrometric solution for Gaia

    Författare :Berry Holl; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astrometry; Catalogs; Methods: data analysis; statistical; numerical; analytical; Space vehicles: instruments; Instrumentation: detectors;

    Sammanfattning : The space astrometry mission Gaia, planned for launch in 2013 by the European Space Agency (ESA), will provide the most comprehensive and accurate catalogue of astrometric data for galactic and astrophysical research in the coming decades. It will observe roughly one billion stars, quasars and other point like objects for which the five astrometric parameters (position, parallax and proper motion) will be determined. LÄS MER

  5. 4. Scaling and Gating Attosecond Pulse Generation

    Författare :Christoph Heyl; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent imaging; Ultrafast electron dynamics; Single attosecond pulses; Attosecond pulse trains; XUV sources; High-order harmonic generation; XUV frequency combs; Fysicumarkivet A:2014:Heyl;

    Sammanfattning : High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. LÄS MER
