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

    Författare :Ulrika Wänström Lindh; Ulrika Wänström-Lindh; Högskolan för design och konsthantverk Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; HUMANITIES; HUMANIORA; 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;

    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

  3. 3. Slow and stopped light by light-matter coherence control

    Författare :Jonas Tidström; Lars Thylén; Mauritz Andersson; Jesper Mørk; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

    Författare :Linda Qviström; Anders Andrén; Herman Bengtsson; Martin Hansson; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; 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

  5. 5. Slippery paths : The performance and canonization of Turkic literature and Uyghur muqam song in Islam and modernity

    Författare :Nathan Light; USA IN Indiana University; []
    Nyckelord :HUMANITIES; HUMANIORA; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; HUMANIORA; SOCIAL SCIENCES; HUMANITIES; Folklore; Song; Islam; Muqam; Modernity; Language; literature and linguistics; Social sciences; Turkic; Canonization; Middle Eastern literature; Uyghur; Performance; China; Asian literature; Turkic languages; Turkiska språk; Literature; Litteraturvetenskap; Religionshistoria; History of Religions;

    Sammanfattning : In the past forty years the fluid Uyghur muqam song tradition has been transformed into a cultural canon used to represent the Uyghur ethnic group within China and on the world stage. Traditional muqam performers have provided the magma of songs that scholars and politicians have edited into an invented "great tradition" which supports a Uyghur claim to an important piece world cultural history.
