  1. 1. Energy Performance and Manoeuvring Modelling of Inland Waterway Vessels

    Författare :Chengqian Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; confinement effect; inland waterways; manoeuvring prediction; autonomous vessels; ship hydrodynamics; energy efficiency;

    Sammanfattning : Inland waterway transport has significant potential to reduce greenhouse emissions and road congestion safely and sustainably. To construct competitive, intelligent waterborne transport networks, the use of advanced vessels with clean energy and a high degree of automation or autonomy is an ideal solution for next-generation transport.

  3. 2. Efficient hull design for ice conditions in inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inland waterway ship; ice conditions; ice properties; ice-hull interaction; ice resistance; impact load; numerical method; operation time window; lightweight design; composites and sandwich structure; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. Usually, IWW ships are designed without ice operation concerns and are structurally weaker than ships designed according to ice-class notifications from the classification societies. LÄS MER

  4. 3. Ice load prediction for design of ice-going ships for inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inland waterway ship; ice load; ice conditions; ice properties; FSICR; probabilistic method; ice-hull interaction; numerical model; structural response; finite element analysis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. However, unlike in western and central European countries, in Nordic countries, e.g. LÄS MER

  5. 4. Vinterbyar : ett bandsamhälles territorier i Norrlands inland, 4500-2500 f. Kr

    Författare :Åsa Lundberg; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; social territory; local band; regional band; language family; settlement pattern; semi-sedentary; late mesolithic; neolithic; semi-subterranean house; winter sites; red slate; pit-falls; cooking pits; scrapers;

    Sammanfattning : The main archaeological features studied in this thesis are semi-subterranean house remains in the woodlands of middle northern Sweden, east of the high mountains and some 100 km from the coast. The period during which they were occupied has been delimited to 4500-2500 BC. LÄS MER

  7. 5. Naturresurser, sågverksbolag och bönder : konflikter i Västernorrland 1863-1906

    Författare :Axelsson Lantz Ewa; Lena Andersson Skog; Hans Jörgensen; Paulina Rytkönen; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic history; sawmill industry; industrialization; conflict resolution; natural resources; local district court; 19th century Northern Sweden; ekonomisk historia; Economic History;

    Sammanfattning : During the nineteenth century, competition over forestland and waterways grew in Northern Sweden. This increased the pressure on existing institutions of natural resource governance. It culminated with a ban on private acquisition of woodland from smallholders in 1906. LÄS MER
