    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stokes flow; rigid particles; accuracy; fundamental solutions; method of images; multiblob; contact avoiding; complementarity problem; barrier method; elliptic PDE; grid optimisation; pair-correction; boundary integral equations; Stokesflöde; noggrannhet; stela partiklar; fundamentallösningar; randintegralekvation; reflektionspunkter; multiblob; kontaktundvikande algoritmer; komplementaritetsproblem; barriärmetod; elliptisk PDE; gridoptimering; parkorrektion; Numerical Analysis; Numerisk analys;

    Abstract : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. READ MORE

  5. 3. Managing variation in hospital patient flows

    Author : Olle Olsson; Erik Sandberg; Mattias Elg; Daniel Ekwall; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Performing healthcare services is a complex practice. With the continuous developments in the medical field, healthcare organisations and professionals have become increasingly specialised, and healthcare services increasingly fragmented. READ MORE

  6. 4. The Hit-IT project : The development and evaluation of an internet-based complex intervention for primary healthcare patients with cardiovascular disease and insomnia

    Author : Sandra Öberg; Anders Broström; Linda Johansson; Jonas Sandberg; Mattias Georgsson; Staffan Karlsson; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; insomnia; cognitive behavioral therapy; internet-based; utility; effect; patient experience; complex intervention;

    Abstract : There is a need to explore insomnia among patients with cardiovascular disease (CVD), since they have increased risk for disease deterioration, poor quality of life and a shorter lifetime expectancy. Cognitive behavioral therapy (CBT) is the main recommended insomnia treatment, although it is a rare treatment choice in the healthcare due to lack of certified CBT therapists. READ MORE
