  1. 6. Deployment Control of Spinning Space Webs and Membranes

    Författare :Mattias Gärdsback; Anders Eriksson; Gunnar Tibert; Thomas W. Murphey; KTH; []
    Nyckelord :Flexible structures; space webs; membranes; solar sails; solar power systems; deployment control; optimal control; centrifugal force deployment; spin deployment; rotation-free; shell elements; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Future solar sail and solar power satellite missions require deployment of large and lightweight flexible structures in space. One option is to spin the assembly and use the centrifugal force for deployment, stiffening and stabilization. LÄS MER

  2. 7. Guided tourism : the role of guidebooks in German tourist behaviour in Sweden

    Författare :Malin Zillinger; Dieter K. Müller; Alan A. Lew; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Car-tourists; Guidebooks; Mobility; Place; Power; Round tour; Space; Time geography; Tourist information; Tourism system; Human geography; Kulturgeografi; Business and economics;

    Sammanfattning : Tourism is a spatial phenomenon. Tourist behaviour on-site is not only dependent on the destination itself, but also on the situation in other places, tourists’ spatial mobility and access to information. On the basis of this argument, the whole tourism system is taken into account in this thesis. LÄS MER

    Författare :Constanze Ackermann-Boström; Dessislava Stoeva-Holm; Susanne Tienken; Leena Huss; Konstanze Marx; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Russian-Germans; community of practice; identity; migration; small stories; multilingualism; linguistic ethnography; narrative; space; positioning; heritage language; proper names; categorization; East Germany; Plattenbau; Russlanddeutsche; Identität; Migration; Mehrsprachigkeit; Linguistische Ethnographie; Raum; Narrative; Positionierung; Herkunftssprache; Eigennamen; Kategorisierung; Ostdeutschland; Plattenbau; German; Tyska;

    Sammanfattning : This thesis focuses on the lived multilingualism of a group of young Russian-German adults who as children migrated together with their families from post-Soviet states to the Federal Republic of Germany during the 1990s. Today these adults live in a ‘Plattenbau’ housing estate in a small town in one of the new federal states of Germany. LÄS MER

  4. 9. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Författare :Hans Kolsters; KTH; []
    Nyckelord :Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.
