  1. 1. Self-Service Recovery

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

    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

  3. 2. Parametric model for astrophysical proton-proton interactions

    Författare :Niklas Karlsson; Per Carlsson; Johan Rathsman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Observations of gamma-rays have been made from objects such as active galaxies and supernova remnants and also as diffuse emission from the Galactic ridge. The study of gamma-rays can provide information about production mechanisms and tell us about cosmic ray acceleration. LÄS MER

  4. 3. Carbothermal synthesis of transition metal carbide and carbonitride whiskers via a Vapour-Liquid-Solid (VLS) growth mechanism

    Författare :Niklas Ahlén; Jan Otto Carlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : A route for the synthesis of TiC, TiCyN1-y, TaxTi1-xC and TaxTi1-xCyN1-y whiskers via a carbothermal Vapour-Liquid-Solid (VLS) growth mechanism, yielding 70-90 vol.% whiskers, has been established. The whiskers were uniform in diameter (0.3-0. LÄS MER

  5. 4. Surface Engineering in Sheet Metal Forming

    Författare :Per Carlsson; Mikael Olsson; Niklas Axén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; wear; metal coated steel sheet; dry lubricants; galling; PVD coatings; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : In recent years, surface engineering techniques have been developed in order to improve the tribological performance in many industrial applications. In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops. LÄS MER

  7. 5. Micro Level Priority Setting for Elderly Patients with Acute Cardiovascular Disease and Complex Needs : Practice What We Preach or Preach What We Practice?

    Författare :Niklas Ekerstad; Per Carlsson; Rurik Löfmark; Kjell Asplund; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Demographic trends and other factors are expected to continue widening the gap between health care demands and available resources, especially in elder services. This growing imbalance signals a need for priority setting in health care. LÄS MER
