  1. 16. Pioneer Settlement in the Mesolithic of Northern Sweden

    Författare :Anders Olofsson; Noel Broadbent; Ingela Bergman; Bo Knarrström; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Mesolithic; pioneer settlement; lithic technology; cultural context; chronology; glacio-isostatic uplift; lake-tilting; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Sammanfattning : The aim of the thesis is to cast light on the earliest settlement of northern Sweden. The starting point is lithic artifacts, which have been studied from a technological as well as a more conventional typological perspective (Papers I, II, and IV). LÄS MER

  3. 17. Wheel–Rail Impact Loads and Track Settlement in Railway Crossings

    Författare :Xin Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle--track dynamics; wheel--rail contact; track settlement; material modelling of ballast; Switches and crossings; turnout; cyclic loading; Green s functions;

    Sammanfattning : Turnouts (Switches & Crossings, S&C) are critical components of a railway track requiring regular maintenance and generating high life cycle costs. A main driver for the high maintenance costs is the need to repair and replace switch rails and crossings as these components are subjected to a severe load environment. LÄS MER

  4. 18. Living on Another Shore : Early Scandinavian Settlement on the North-Western Estonian Coast

    Författare :Felicia Markus; Anders Kaliff; Göran Hoppe; Kerstin Cassel; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Estonia; Estonian Swedes; Scandinavian settlement; Iron Age; early Medieval Period; colonisation; ethnic identity; migration; Baltic Sea; contacts; Christianisation; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Sammanfattning : Prior to the Second World War, there was a Swedish-speaking population settled on the north-western Estonian coasts. The early history of this group is largely unknown. No colonisation is mentioned in the written sources. The earliest such sources that mention Swedes originate in the late thirteenth century. LÄS MER

  5. 19. Simulation of track settlement in railway turnouts-An iterative approach

    Författare :Xin Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track settlement; Railway switch and crossing; cyclic loading; visco-plasticity; vehicle‒track interaction; 3D finite element analysis; granular material; ballast;

    Sammanfattning : In this thesis, a methodology for simulation of track settlement in railway turnouts (switches andcrossings, S&C) is presented. The methodology predicts the accumulated settlement for a given setof traffic loads using an iterative and cross-disciplinary procedure. LÄS MER

  7. 20. Norra Spånga : bebyggelse och samhälle under järnåldern

    Författare :Anita Biuw; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Spånga; Ärvinge; Iron Age; settlement; society;

    Sammanfattning : This thesis is mainly based on funerals and deals with the structure during the Iron Age in northern Spånga in the south of Uppland, Sweden. The investigation area is about 3x7 kilometres large and is situated about 12 kilometres from the centre of Stockholm. Geographically it is part of two river-valleys. LÄS MER
