    Sammanfattning : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. LÄS MER

  3. 2. Moral Illusions

    Författare :Kajsa Hansson; Gustav Tinghög; Emil Persson; Kinga Barrafrem; Topi Miettinen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Selfish behavior; Preferences for redistribution; Moral behavior; Själviskt beteende; Preferenser för omfördelning; Moraliskt beteende;

    Sammanfattning : Just as optical illusions can trick our visual senses, our moral sense can be misguided by moral illusions. In this thesis, I investigate whether moral illusions can arise from mental shortcuts (availability bias), cognitive biases (attribution bias), contextual factors (possibility to avoid information), and decision rules (democratic decision-making).

  4. 3. 2D and 3D Halftoning for Appearance Reproduction

    Författare :Fereshteh Abedini; Sasan Gooran; Daniel Nyström; Jan Morovic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The appearance of an object is determined by its chromatic and geometric qualities in its surrounding environment using four optical parameters: color, gloss, translucency, and surface texture. Reconstructing the appearance of objects is of great importance in many applications, including creative industries, packaging, fine-art reproduction, medical simulation, and prosthesis-making.
