  1. 1. Procurement Performance Measurement System

    Författare :Daniel Knudsen; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The procurement process can be defined as all the activities required in getting a product or a service from the supplier to a final destination. It encompasses the purchasing function, storing, transportation and manages the relations between suppliers and internal customers. LÄS MER

  3. 2. Improving Procurement Performance with E-business Mechanisms

    Författare :Daniel Knudsen; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell ekonomi; Commercial and industrial economics; e-procurement; e-business; procurement; purchasing;

    Sammanfattning : E-procurement — e-business mechanisms deployed on procurement — offers many recent and innovative methods that can improve procurement in different ways. The key challenge of e-procurement, however, is how to apply the various e-procurement applications in such a way that they improve the procurement practice and sourcing strategy of a company.

  4. 3. An NADH-Coupled Biosensor for Engineering Redox Metabolism in Saccharomyces cerevisiae

    Författare :Jan Knudsen; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Yeast; redox balance; glycerol whole-cell biocatalysis; single-cell monitoring; FACS;

    Sammanfattning : Baker’s yeast, Saccharomyces cerevisiae’s potential in industrial biotechnology for producing valuable products e.g. biofuels, bulk chemicals, bio-flavours and pharmaceuticals is established. LÄS MER

  5. 4. Some Aspects of Wear and Structural Dynamics

    Författare :Jakob Knudsen; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Sammanfattning : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. LÄS MER

  7. 5. Vibro-impact dynamics of fretting wear

    Författare :Jakob Knudsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The dynamics and wear of non-linear impact oscillators, comprising a single-degree of freedom system as well as continuous beam systems are analysed. The considered beams are of cantilever type with the lateral motion of the free end constrained by elastic supports. They are modelled as Bernoulli beams with Rayleigh damping. LÄS MER
