  1. 1. The Visible and the Invisible : Color Contrast Phenomena in Space

    Författare :Gertrud Olsson; Jadwiga Krupinska; Henrik Oxvig; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color in architecture; color theory; color phenomena; simultaneous contrast; simultané; afterimage; transparency; material and immaterial; color mixture; light-colors; Art; Konstvetenskap; Architecture; Arkitektur;

    Sammanfattning : This study deals with the changes in color that arise in space, primarily simultaneous contrast in three dimensions. The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. LÄS MER

  3. 2. It's All in the Brain : A Theory of the Qualities of Perception

    Författare :Jesper Östman; Pär Sundström; Howard Robinson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Philosophy of perception; philosophy of consciousness; hallucination; phenomenal qualities; qualia; sense data; physicalism; Russell; disjunctivism; representationalism; brain theory; color; the brain; Theoretical Philosophy; teoretisk filosofi;

    Sammanfattning : This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. LÄS MER

  4. 3. Group-Theoretical Structure in Multispectral Color and Image Databases

    Författare :Thanh Hai Bui; Reiner Lenz; Björn Kruse; Jinhui Chao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group theory; PCA Principal Component Analysis ; CBIR; Content-based Image Retrieval ; filter; color; image; multispectral; database; Signal processing; Signalbehandling;

    Sammanfattning : Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. LÄS MER

  5. 4. Noise sensitivity and FK-type representations for Gaussian and stable processes

    Författare :Malin Palö Forsström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; color representation; exclusion process; color process; Noise sensitivity; threshold stable vector; volatility; noise stability; interchange process; threshold Gaussian vector; multivariate stable distribution; Bernoulli random vector; mixing time;

    Sammanfattning : This thesis contains four papers on probability theory. Paper A concerns the question of whether the exclusion sensitivity and exclusion stability of a sequence of Boolean functions are monotone with respect to adding edges to the underlying sequence of graphs. LÄS MER

  7. 5. Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality

    Författare :Lucia M. Garozzo; Henrik Johansson; Chris White; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; double copy; gauge theory; string theory; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. LÄS MER
