  1. 36. The power and the glory : the sculptures of the warship Wasa

    Författare :Hans Soop; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Vasa regalskepp ;

    Sammanfattning : In 1956 the wreck of the 64-gun Swedish warship Wasa, sunk on her maiden voyage in the harbour of Stockholm the 10th of August 1628, was found at a depth of 32 metres. Preparations for salvaging the ship started, and in April 1961 the Wasa broke the surface after 333 years on the sea bottom. LÄS MER

  3. 37. 3D-woven Reinforcement in Composites

    Författare :Fredrik Stig; Stefan Hallström; Dan Zenkert; Andrew Long; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. LÄS MER

  4. 38. Baltzar von Platen, Thomas Telford och Göta kanal : Entreprenörskap och tekniköverföring i brytningstid

    Författare :Lars Strömbäck; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; canal construction; development block; entrepreneur; the Gotha Canal; Göta kanal; Motala verkstad; von Platen; technology transfer; Telford; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The Gotha Canal was built during 1810-1832 and it was the biggest building enterprise that Sweden up to that time had undertaken. To a poor and preindustrialised country the whole project was economically as well as technically a tremendous challenge. LÄS MER

  5. 39. Autonomous Localization in Unknown Environments

    Författare :Jonas Callmer; Fredrik Gustafsson; Paul Havinga; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; indoor positioning; heading estimation; magnetometers;

    Sammanfattning : Over the last 20 years, navigation has almost become synonymous with satellite positioning, e.g. the Global Positioning System (GPS). On land, sea or in the air, on the road or in a city, knowing ones position is a question of getting a clear line of sight to enough satellites. LÄS MER

  7. 40. Large eddy simulation of cavitating and non-cavitating flow

    Författare :Tobias Huuva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high Reynolds number; Cavitation; turbulence; RANS; hydrodynamics; numerical simulation; modelling; DES; LES;

    Sammanfattning : Most marine configurations are subject to a number of complex and important hydrodynamic phenomena affecting the overall performance of the vessel, both regarding resistance and propulsive efficiency. In this thesis, the possibility of numerically simulating some of these phenomena is investigated. LÄS MER
