  1. 16. Imperfections in Recycled Aluminium-Silicon Cast Alloys

    Författare :Anton Bjurenstedt; Anders Jarfors; Salem Seifeddine; Pål Schmidt; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled cast Al-Si alloy; Fe-rich particles; Melt quality; Fractography; Differential scanning calorimetry.;

    Sammanfattning : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. LÄS MER

  3. 17. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  4. 18. Surface Characterization using Radiometric and Fourier Optical Methods

    Författare :Peter Hansson; Arne Roos; Mikael Sjödahl; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Radiometry; Fourier Optics; Surface Characterization; Topography; Reflectance; Color; Paper; Printing; Print quality; Gloss; Light scattering; Shape from shading; Photometric stereo; Optical motion compensation; Filtering; Wiener filter; Lamberts law; Image analysis; Image processing; Machine vision; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER

  5. 19. Ink-paper interactions and effect on print quality in inkjet printing

    Författare :Anna Lundberg; Magnus Lestelius; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Other physics; Övrig fysik;

    Sammanfattning : This thesis concerns paper and ink interactions related to inkjet printing. Themain purpose of this work was to gain a deeper understanding in whichparameters control the flow of ink into papers and how the ink interacts with thepaper surface. The overall objective was to find key parameters to optimize theprint quality in inkjet printing. LÄS MER

  7. 20. En elev - en dator : kunskapsbildningens kvalitet och villkor i den datoriserade skolan

    Författare :Håkan Fleischer; Elsie Anderberg; Thomas Karlsohn; Lars Naeslund; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social Sciences; Educational Sciences; Pedagogy; Samhällsvetenskap; Utbildningsvetenskap; Pedagogik; One-to-one; knowledge formation; knowledge qualities; phenomenology; phenomenography; knowledge society; stretched knowledge; performative knowledge; En-till-en; kunskapsbildning; kunskapskvalitet; fenomenologi; fenomenografi; kunskapssamhälle; stretchad kunskap; performativ kunskap; Pedagogik; Pedagogics;

    Sammanfattning : Avhandlingen behandlar införande av varsin dator till elever och lärare, här kallat en-till-en. Syftet är att bidra med kunskap om hur en-till-en påverkar lärande. Särskilt fokus ligger på kunskapsproduktionens karaktär och kvalitet och på förhållanden i den svenska skolan. LÄS MER
