  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. Ink-paper interaction : a study in ink-jet color reproduction

    Författare :Li Yang; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. LÄS MER

  4. 3. Electrochromism and over-oxidation in conjugated polymers: Improved color switching and a novel patterning approach

    Författare :Payman Tehrani; Magnus Berggren; Nathaniel D Robinson; Ludvig Edman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conjugated polymers; Over-oxidation; Patterning; Electrochromism; PEDOT:PSS; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : During the last 30 years a new research and technology field of organic electronic materials has grown thanks to a groundbreaking discovery made during the late 70’s. This new field is today a worldwide research effort focusing on exploring this new class of materials that also enable many new areas of electronics applications. LÄS MER

  5. 4. Dynamic and quasi-stationary electrochromic response of amorphous tungsten oxide thin films : In situ combined electrochemical and optical measurements during lithium intercalation

    Författare :Edgar Alonso Rojas González; Gunnar Niklasson; Aline Rougier; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochromism; Optical absorption; Amorphous materials; Tungsten oxide; Electrochemical impedance spectroscopy; Color impedance spectroscopy; Intercalation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Electrochromic (EC) materials can adjust their optical properties, reversibly, by means of an external electrical stimulus. They have relevant technological applications; for example, energy-efficient smart windows, which can adapt dynamically—according to the given environmental conditions—to control the heat and visible light fluxes between the interior and exterior of a building.

  7. 5. Characterization of Halftone Prints based on Microscale Image Analysis

    Författare :Mahziar Namedanian; Sasan Gooran; Jon Yngve Hardeberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Ink spreading and lateral light scattering in the substrate affect the color of a halftone print. One of the most important phenomena which affects the print result is dot gain, meaning that printed dots appear larger than the dots in the digital bitmap. LÄS MER
