  1. 1. Measurement systems and process orientation with focus on the order process

    Författare :Anders Ljungberg; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process measurement; measurement systems; process management; measurement; Technological sciences; Teknik;

    Sammanfattning : The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. LÄS MER

  4. 3. EMC barriers : measurement methodologies and model verification

    Författare :Urban Lundgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : The subject of Electromagnetic Compatibility (EMC) is introduced. A short overview of the regulatory EMC requirements in Europe and in the United States is presented. An explanation is given why it is important for people in the electronics business to understand the need for EMC regulations. LÄS MER

  5. 4. Stochastic model updating and model selection with application to structural dynamics

    Författare :Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

    Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

  7. 5. Multi-Timescale Modelling of Ethernet Traffic

    Författare :Patrik Carlsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethernet Traffic Model; Multi-Timescale; Multifractal; Bit Rate; Moments; Fluid Flow Analysis; Model Matching; Measurement;

    Sammanfattning : Ethernet is one of the most common link layer technologies, used in local area networks, wireless networks and wide area networks. There is however a lack of traffic models for Ethernet that is usable in performance analysis. In this thesis we describe an Ethernet traffic model. LÄS MER
