  1. 1. Self-Service Recovery

    Författare :Niklas E. Johansson; Anders G. Nilsson; Bo Edvardsson; Sten Carlsson; Jan Lindvall; Niklas Johansson; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Service recovery; self-service technology; self-service recovery; IT-enabler; value creation; Informatics; Informatik; Information Systems; Informatik; Service recovery SR ; self-service technology SST ; self-service recovery SSR ;

    Sammanfattning : Service recovery is about problems. What happens when customers experience problems? Well, sometimes customers complain to the one responsible for the service. Sometimes customers do not complain but instead tell somebody else about the problem, possibly leading to a bad reputation for the one responsible for the service. LÄS MER

  2. 2. Evolution of Plants : a mathematical perspective

    Författare :Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evolution; plants; mathematics; optimization; optimal control; adaptive dynamics; flowering; seasons; tree crown; drought; taproot; trade-off; strategy; trait; ESS; NPP; LAI; Red Queen; Mathematics; matematik;

    Sammanfattning : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. LÄS MER

  3. 3. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone

    Författare :Björn G. Johansson; Göran Arnqvist; Fredrik Widemo; Anders Berglund; Allen Moore; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Drosophila grimshawi; sexual selection; pheromone; mate choice; lekking; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Chemical signals are the most widely used form of sexual communication throughout the living world. However, there is in general little knowledge about what these signals actually communicate. The role of chemical signals, i.e. LÄS MER

  4. 4. Dynamic ultrasound investigation of clubfeet, 0 - 4 years of age, with normal controls

    Författare :Arne G. Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clubfoot; ultrasonography; Ponseti treatment; congenital deformities; range of movement; repeatability; longitudinal study;

    Sammanfattning : Clubfoot is one of the most common congenital deformities, 1-6/1,000 births in Europe and up to 5-6/1,000 in Polynesia. The Ponseti method is now widely regarded as the method of choice for treatment. The treatment starts soon after birth using manipulations and castings until the deformities are corrected, usually 6-10 weeks. LÄS MER

  5. 5. Duality-based adaptive finite element methods with application to time-dependent problems

    Författare :August Johansson; Mats G. Larson; Paul Houston; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; finite element methods; dual-weighted residual method; multiphysics; a posteriori error estimation; adaptive algorithms; discontinuous Galerkin; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : To simulate real world problems modeled by differential equations, it is often not sufficient to  consider and tackle a single equation. Rather, complex phenomena are modeled by several partial dierential equations that are coupled to each other. LÄS MER
