  2. 1. Thermal adaptation along a latitudinal gradient in damselflies

    Author : Viktor Nilsson-Örtman; Frank Johansson; Karl Gotthard; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth rate; metabolic theory of ecology; universal temperature dependence; environmental gradients; thermal performance; thermal sensitivity; environmental variability; optimality theory; life history; acclimation; size structure; competition; cannibalism; intraguild predation;

    Abstract : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

  4. 2. Sensitivity and Uncertainty Analysis of BWR Stability

    Author : Ivan Gajev; Tomas Lefvert; Paolo Vinai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; Engineering physics; Teknisk fysik; SRA - Energy; SRA - Energi;

    Abstract : Best Estimate codes are used for licensing, but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

  5. 3. Modelling and Simulation of Thermal Radiation in Biomass Combustion

    Author : Thomas Nilsson; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat load; gas turbine; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; porous media; fixed bed; biomass; wood; FG-DVC; combustion; DOM; P1-approximation; Mie theory; RDG-PFA; EWBM; thermal radiation; soot;

    Abstract : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. READ MORE

  6. 4. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

    Author : Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

    Abstract : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

  7. 5. The Plastic Flow Behaviour of Aluminium Alloys Exhibiting Dynamic Strain Ageing

    Author : Magnus Hörnqvist Colliander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Zn-Mg; Dynamic strain ageing; Strain rate sensitivity; Portevin-Le Chatelier effect; Temperature sensitivity; Thermal activation;

    Abstract : The phenomenon known as dynamic strain ageing, abbreviated DSA, has been known since the beginning of last century. It was first discovered as serrations in the load-elongation curve obtained upon deforming specimens of certain alloys in tension. This phenomenon became known as the Portevin-Le Chatelier (PLC) effect. READ MORE
