  1. 16. Systems Modeling Approaches to Physical Resource Management : An Industrial Ecology Perspective

    Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industrial Ecology; Industriell ekologi;

    Sammanfattning : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. LÄS MER

  3. 17. Provtagnings- och analysstrategi för lämplig mätosäkerhet

    Författare :Patrik von Heijne; Jenny Norrman; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Prior to the remediation of brownfields, extensive sampling and analysing isdone. The planned and reached measurement uncertainties are seldom asked forcontracting such types of investigations. Therefore they are usually not statednor discussed in the tenders. LÄS MER

  4. 18. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

    Författare :Linus Andersson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced order modeling; Substructuring; Nonlinear dynamics; Geometrically nonlinear; Modal derivatives; Blast loading; Soft-body impact; Glass structures;

    Sammanfattning : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. LÄS MER

  5. 19. Analysis of underground concrete pipelines subjected to seismic high-frequency loads

    Författare :Roghayeh Abbasiverki; Anders Ansell; Jan Laue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Earthquake; High-frequency; Underground; Pipelines; Reinforced concrete; Inclined bedrock; Jordbävning; Högfrekvent; Underjordisk; Rörledningar pipelines ; Armerad betong; Lutande berggrund; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.

  7. 20. Stratigraphy and facies of Middle Silurian epicontinental carbonate platform deposits of Gotland, Sweden

    Författare :Mikael Calner; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysisk geografi; Geologi; Geology; physical geography;

    Sammanfattning : The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of these deposits.
