  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?”.

  3. 2. Light shapes spaces : experience of distribution of light and visual spatial boundaries

    Författare :Ulrika Wänström Lindh; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Practise-based design research; distribution of light; lighting design; architecture; enclosure; perceived dimensions; atmosphere; light zones; light topography; visual spatial boundaries; Practise-based design research; distribution of light; lighting design; architecture; enclosure; perceived dimensions; atmosphere; light zones; light topography; visual spatial boundaries;

    Sammanfattning : Light enables us to experience space. The distribution of light is vital for spatial experience but has not been the main focus of previous research on lighting. The lighting designer’s professional knowledge is to a great extent experience-based and tacit. LÄS MER

  5. 4. Slow and stopped light by light-matter coherence control

    Författare :Jonas Tidström; Lars Thylén; Mauritz Andersson; Jesper Mørk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slow light; stored light; stopped light; light-matter coherence; electromagnetically induced transparency; rubidium atoms; Physics; Fysik; Photonics; Fotonik;

    Sammanfattning : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. LÄS MER

  7. 5. 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
