  1. 1. Interfacial Adhesion Failure : Impact on print-coating surface defects

    Författare :Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER

  2. 2. Aerodynamics of two trucks driving in close-proximity

    Författare :Johannes Törnell; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; drag; aerodynamics; cab over engine; inter-vehicle distance; lateral offset; side wind; truck; platooning; yaw; close proximity; wake;

    Sammanfattning : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. LÄS MER

  3. 3. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Författare :Gabrielle Flood; Matematik LTH; []

    Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER

  4. 4. Electron beam melting of Alloy 718 : Influence of process parameters on the microstructure

    Författare :Paria Karimi Neghlani; Joel Andersson; Per Nylén; Joakim Ålgårdh; Högskolan Väst; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Powder bed fusion; Electron beam melting; Part’s orientation; Microstructure development; Single track; Energy input; Focus offset; Geometrical features; Alloy 718; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : Additive manufacturing (AM) is the name given to the technology of building 3D parts by adding layer-by-layer of materials, including metals, plastics, concrete, etc. Of the different types of AM techniques, electron beam melting (EBM), as a powder bed fusion technology, has been used in this study.

  5. 5. Environmental compensation using Resource Equivalency Analysis (REA) and Habitat Equivalency Analysis (HEA): is it just for the birds? : determining whether society is better off following resource-based compensation

    Författare :Scott Cole; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Environmental compensation is the provision of natural resources through a restoration project, which is scaled to ensure the public is compensated for the environmental damage. The European Union (EU) recently implemented the Environmental Liability Directive (ELD), requiring that environmental damage be remediated (restored) so that the affected environment returns to (or toward) its baseline condition and the public is compensated for the initial damage and the losses during the time it takes for the environment to recover (interim losses).
