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

    Author : Federico Favero; Roberto Bresin; Arne Lowden; Ute Besenecker; Sergio Altomonte; KTH; []
    Keywords : 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;

    Abstract : 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. Computational Light Field Photography : Depth Estimation, Demosaicing, and Super-Resolution

    Author : Yongwei Li; Mårten Sjöström; Roger Olsson; Paolo Favaro; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light field; computational photography; depth estimation; demosaicing; super-resolution;

    Abstract : The transition of camera technology from film-based cameras to digital cameras has been witnessed in the past twenty years, along with impressive technological advances in processing massively digitized media content. Today, a new evolution emerged -- the migration from 2D content to immersive perception. READ MORE

  3. 3. Mathematical Modelling of Light Scattering in Paper and Print

    Author : Per Edström; Mårten Gulliksson; Inge Söderkvist; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; radiative transfer; solution method; numerical stability; speed; light scattering; light absorption; Kubelka-Munk; errors; reflectance calculations; MATHEMATICS; MATEMATIK;

    Abstract : A problem formulation and a solution method are outlined for the radiative transfer problem in vertically inhomogeneous scattering and absorbing media, using discrete ordinate model geometry. The treatment spans from the physical problem via a continuous formulation, a discretization and a numerical analysis, to an implementation with performance evaluation and application to real-world problems.

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

    Author : E. Mattias Lindh; Ludvig Edman; Thomas Wågberg; Thomas Lanz; Sebastian Reineke; Umeå universitet; []
    Keywords : 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;

    Abstract : 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.
