  1. 1. 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

    Författare :AMOGH VEDANTHA KRISHNA; Bengt Göran Rosén; Frederic Cabanettes; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-based Powder bed fusion; Fused deposition modeling; Structured light projection; Stylus profilometer; Multiple regression; Areal surface texture parameters; Profile parameters; Feature-based characterization; Power spectral density; Scale-sensitive fractal analysis; Confocal fusion; Additive manufacturing;

    Sammanfattning : Additive Manufacturing (AM) is on the verge of causing a downfall to conventional manufacturing with its huge potential in part manufacture. With an increase in demand for customized product, on-demand production and sustainable manufacturing, AM is gaining a great deal of attention from different industries in recent years. LÄS MER
