  2. 1. Assessment of Interruption Costs in Electric Power Systems using the Weibull-Markov Mode

    Author : Jasper van Casteren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi-Markov model; interruption cost; power system reliability; customer damage function; duration distribution; reliability worth;

    Abstract : Modern competitive electricity markets do not ask for power systems with the highest possible technical perfection, but for systems with the highest possible economic efficiency. Higher efficiency can only be reached when accurate and flexible analysis tools are used. READ MORE

  4. 2. Power system reliability assessment using the Weibull-Markov model

    Author : Jasper van Casteren; Chalmers tekniska högskola; []

  5. 3. A Quantitative Approach to Computer Security from a Dependability Perspective

    Author : Erland Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intrusions; computers; modelling; vulnerability; dependability evaluation; experimentation; terminology; operational security; reliability; concepts; measures;

    Abstract : Security and dependability represent two very important attributes of modern computer systems, especially in the light of the increasing complexity and criticality of these systems. These two disciplines have traditionally been treated separately, although lately some attempts have been made to integrate them. READ MORE

  6. 4. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation

    Author : Jimmy Ehnberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generation reliability; Isolated power systems; Wind power; Solar power; Renewable energy; Stochastic modelling;

    Abstract : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. READ MORE

  7. 5. A statistical approach to multi-input equivalent fatigue loads for the durability of automotive structures

    Author : Gwenaelle Genet; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Equivalent fatigue; uniaxial and multiaxial high cycle fatigue; multi-input variable amplitude loads; rainflow counting; Morel s model; Basquin s model; Gaussian process; Markov chain; Markov chain;

    Abstract : In the automotive industry, due to temporal and financial constraints, we need to strongly reduce the duration of the design phase, but still ensure reliability and robustness. Structures in service are often exposed to complex variable amplitude loads. READ MORE
