    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Företagsekonomi; Business Administration; Företagsekonomi;

    Sammanfattning : Already in the mid-seventies it was concluded that there are very few, if any, ‘pure’ goods or services. Nevertheless, over 20 years later, most publications on services focus on how service characteristics differ from goods. LÄS MER

  4. 3. Device Technology Based on High Temperature Superconductors and Microwave Breakdown in Gases

    Författare :Martin Löfgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distortion; penetration depth; surface resistance; transmit-receive switch; coupled-grain model; high-power; microwave; pulse; surface impedance; breakdown; propagation; modulator; air; superconductor; transmission line; resonator; coplanar waveguide; plasma;

    Sammanfattning : This thesis deals with two separate fields of microwave technology. The first section treats microwave characterization and applications of high temperature superconducting (HTS) thin films, while the second section treats microwave breakdown in transmit-receive (TR) switches and in air. Within the first section, four main topics are adressed. LÄS MER

  5. 4. Diffusive properties of granitic rock as measured by in-situ electrical methods

    Författare :Martin Löfgren; Ivers Neretnieks; Peter Vilks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Diffusion into the rock matrix has been identified as one of the most important retention mechanisms for dissolved contaminants in fractured crystalline rock. In this thesis the diffusive properties of granitic rock, described by the formation factor, have been investigated by electrical methods. LÄS MER

  7. 5. The Leader of the Pack : A Service Perspective on Packaging and Customer Satisfaction

    Författare :Martin Löfgren; Anders Gustafsson; Lars Witell; Bo Edvardsson; Bo Bergman; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Customer satisfaction; Kano; Packaging; Business studies; Företagsekonomi; Business Administration; Företagsekonomi;

    Sammanfattning : Almost everything we as consumers buy in a store has a package. Packages have many functions – some, if not all, present marketers with the opportunity to gain competitive advantages. LÄS MER
