  1. 1. Light Rhythms : Exploring the Perceptual and Behavioural Effects of Daylight and Artificial Light Conditions in a Scandinavian Context

    Författare :Federico Favero; Roberto Bresin; Arne Lowden; Ute Besenecker; Sergio Altomonte; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Lighting design; Context; Light; Behaviour; Perception of light; Perception of time; Associative aspects; Architecture; Daylight; Media Technology; Medieteknik;

    Sammanfattning : This compilation thesis collects multidisciplinary work on the study of the impact of light rhythms on perception and behaviour. The thesis was structured to answer and discuss the questions: “How does a person feel and behave inan illuminated space?” and “Do variable light conditions influence perception, appraisal and motion?”.

  2. 2. Light for a brighter morrow : paving the way for sustainable light-emitting devices

    Författare :Petter Lundberg; Ludvig Edman; Thomas Wågberg; Magnus Jonsson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Artificial Light; Organic Electronics; Photophysics; Light-emitting Electrochemical Cells; Thermally Activated Delayed Fluorescence; Host-Guest; Sustainability; Solution Processing; fysik; Physics;

    Sammanfattning : We live in an artificially lit world, where light enhances our productivity and improves our quality of life. Today our appetite for light is stronger than ever, and emerging light-emitting technologies do not just replace the classical incandescent light bulb, they also open up for a new world of applications.

  3. 3. Rum utan utsikt : Fönster och ljus i medeltida byggnader

    Författare :Linda Qviström; Anders Andrén; Herman Bengtsson; Martin Hansson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Medieval Archaeology; Post Medieval Archaeology; Windows; Medieval Buildings; Light Openings; Window Glass; View; Interiors; Darkness; Light; Lighting; Light Equipment; Arkeologi; historisk arkeologi; medeltida byggnader; fönster; ljusöppningar; fönsterglas; utsikt; inomhusmiljö; mörker; ljus; belysning; belysningsredskap; Uppland; Gotland; arkeologi; Archaeology;

    Sammanfattning : Windows, light and a view are self-evident parts of contemporary interiors. This was not the case in Scandinavia during the Middle Ages (c. 1050–1520 CE), when closed spaces without wall openings were standard. LÄS MER

  4. 4. On the operation of light-emitting electrochemical cells

    Författare :E. Mattias Lindh; Ludvig Edman; Thomas Wågberg; Thomas Lanz; Sebastian Reineke; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Artificial Light; Organic Electronics; Light-emitting Electrochemical Cells; Electrochemical Doping; Thin-film Optical Model; Optical Modes;

    Sammanfattning : We are in the midst of a technological revolution that permeates nearly all human activities; artificial light is one of the most visible contributors in this societal change. If more efficient, green, and versatile light sources can be developed, they might improve the life of millions of people around the world while causing minimal damage to our climate and environment.

  5. 5. Quantum Coherence for Light Harvesting

    Författare :David Palecek; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Sammanfattning : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. LÄS MER
