  2. 1. Absorption of Sound : On the effects of field interaction on absorber performance

    Author : Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. READ MORE

  5. 3. Visualization of Air Flow, Temperature and Concentration Indoors : Whole-field measuring methods and CFD

    Author : Mathias Cehlin; Mats Sandberg; Alfred Moser; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Whole-field;

    Abstract : The thermal indoor climate is a complicated combination of a number of physical variables, all of which strongly affect people’s well-being. The indoor climate not only heavily affects people’s health and life quality, but also their productivity and ability to work efficiently. READ MORE

  6. 4. Regional and local variation in plant species richness

    Author : Cecilia Dupré; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; coastal meadows; deciduous forests; dry grasslands; grazing; habitat configuration; habitat quality; hump-shaped curve; life history traits; regional species pool; soil factors; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Abstract : In this thesis, I examine the variation in plant species richness along gradients of productivity and disturbance in grasslands and forest habitats in southern Sweden, and I compare the documented patterns with theoretical predictions. Moreover, I evaluate the relative importance of habitat quality and habitat configuration for the occurrence of field layer species in deciduous forests. READ MORE

  7. 5. Flexibility from local resources: Congestion management in distribution grids and carbon emission reductions

    Author : Nima Mirzaei Alavijeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; local energy system; local flexibility market; emission abatement strate- gies; congestion management; distribution system operator;

    Abstract : Flexibility from local energy systems has been discussed as a facilitator for the transition towards a more carbon-neutral energy system. Two use cases of this flexibility are congestion management in electricity distribution networks, and an individual-driven reduction of carbon footprints. READ MORE
