  2. 1. Colorimetric and Multispectral Image Acquisition

    Author : Daniel Nyström; Björn Kruse; Carl-Magnus Fahlcrantz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Spectral reconstruction; Device characterization; Image analysis; Bildanalys;

    Abstract : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

  4. 2. From Responsive Interfaces to Honeycomb Membranes by Controlled Radical Polymerisation

    Author : Daniel Nyström; Anders Hult; Søren Hvilsted; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isoporous membranes; Silica nanoparticles; ATRP; Functional surfaces; cellulose; Polymer chemistry; Polymerkemi;

    Abstract : In this study, surface modification of both organic and inorganic substrates (in terms of cellulose and silica nanoparticles, respectively) has been explored using surface-initiated atom transfer radical polymerisation (ATRP). The desire to modify bio-based materials to fit into new application areas and the need for bio-based materials with improved material properties is steadily increasing due to environmental concern.

  5. 3. High Resolution Analysis of Halftone Prints : A Colorimetric and Multispectral Study

    Author : Daniel Nyström; Björn Kruse; Markku Hauta- Kasari; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Halftone print; Dot gain; Image analysis; Bildanalys;

    Abstract : To reproduce color images in print, the continuous tone image is first transformed into a binary halftone image, producing various colors by discrete dots with varying area coverage. In halftone prints on paper, physical and optical dot gains generally occur, making the print look darker than expected, and making the modeling of halftone color reproduction a challenge. READ MORE

  6. 4. Firm Dynamics : The Size and Growth Distribution of Firms

    Author : Daniel Halvarsson; Kristina Nyström; Joachim Wagner; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Firm size distribution; High-growth firms; Gazelles Firm growth- rate distribution;

    Abstract : This thesis is about firm dynamics, and relates to the size and growth-rate distribution of firms. As such, it consists of an introductory and four separate chapters. READ MORE

  7. 5. 2D and 3D Halftoning for Appearance Reproduction

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

    Abstract : 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.
