  2. 1. On the hosting capacity of distribution networks for solar power

    Author : Enock Mulenga; Math Bollen; Nicholas Etherden; Luis (Nando) Ochoa; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aleatory; distribution networks; epistemic; hosting capacity; overvoltage; solar power; stochastic; Electric Power Engineering; Elkraftteknik;

    Abstract : The future will bring changes in energy production and consumption that will affect the performance of electricity distribution networks. Electric vehicle charging will increase consumption; the installation of solar photovoltaic (PV) units will increase production. Both will change the energy flow and affect the power quality.

  4. 2. Development of Risk Oriented Accident Analysis Methodology for Assessment of Effectiveness of Severe Accident Management Strategy in Nordic BWR

    Author : Sergey Galushin; Pavel Kudinov; Harri Tuomisto; KTH; []
    Keywords : Severe accident management; sensitivity; uncertainty; MELCOR; ROAAM; Svår haverihantering; känslighet och osäkerhetsanalys; MELCOR; ROAAM; Fysik; Physics;

    Abstract : Nordic Boiling Water Reactor (BWR) design employs ex-vessel debris coolability as a severe accident management strategy (SAM). In case of a severe accident, the debris ejected from the vessel are expected to fragment, quench and form a debris bed, which is coolable by a natural circulation of water. READ MORE

  5. 3. Robust analysis of uncertainty in scientific assessments

    Author : Ivette Raices Cruz; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; expert knowledge; robust Bayesian analysis; scientific assessments; subjective probability; uncertainty analysis;

    Abstract : Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. READ MORE

  6. 4. Probabilistic Stability Analysis of Underground Mine Excavations

    Author : Musa Adebayo Idris; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Abstract : The creation of underground mine excavation disturbs the original state of the rock mass surrounding the excavation which often leads to instability of the excavation. This poses a threat to the safety of personnel and equipment in and around such excavations. READ MORE

  7. 5. Experiments, Computations and Models for Probabilistic HCF Design

    Author : Daniel Sandberg; Mårten Olsson; Gunnar Härkegård; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : High Cycle Fatigue (HCF) failure is a common failure type for many mechanical components. Traditional HCF design is based on the deterministic safety factor approach, typically used in conjunction with the point stress method. READ MORE
