  1. 6. Quantitative microscopy of coating uniformity

    Författare :Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

    Sammanfattning : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

  3. 7. Verkstadsmiljöer under 1800-talet

    Författare :Eva Dahlström; KTH; []
    Nyckelord :;

    Sammanfattning : The study is concerned with the establishment of Swedishengineering industry during the 19th century, with particularattention given to industrial plants and the formation of thebuilt up environment. The primary aim is to discuss theinfluence of older forms of manufacture and the transfer of newforeign technology. LÄS MER

  4. 8. Förutsättningar för elevers textskapande : En studie om digitala resurser, multimodalitet och elevers handlingsmöjligheter

    Författare :Helene Dahlström; Lena Boström; Ulla Damber; Per-Olof Erixon; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agency; digital resources; literacy; multimodality; text making;

    Sammanfattning : Modern society is characterised by change. Humans’ ways of communicating have changed in many ways due to society’s social, linguistic, cultural and textual plurality. The digitalisation of society has contributed considerably to the changed conditions for communication and representation that have emerged. LÄS MER

  5. 9. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

    Författare :Jessica Dahlström; Förbränningsmotorer; []
    Nyckelord :internal combustion engines; heat transfer; diesel engine; Diesel combustion; combustion chamber geometry; piston geometry; spray parameters;

    Sammanfattning : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. LÄS MER

  7. 10. Experimental Studies of Advanced Ignition Systems for Lean Burn Natural Gas Engines

    Författare :Jessica Dahlström; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ignition system; spark energy; internal combustion engine; engine; spark ignition; natural gas;

    Sammanfattning : One of the greatest challenges for the transport sector today is reducing its environmental impact. This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. LÄS MER
