  1. 6. A Critical Review of the Observational Method

    Författare :Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. LÄS MER

  3. 7. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER

  4. 8. Supporting Information Security Management : Developing a Method for Information Classification

    Författare :Erik Bergström; Rose-Mharie Åhlfeldt; Fredrik Karlsson; Eva Söderström; Steven Furnell; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information classification; Information security management; Information security management systems; Information classification method; INF303 Informationssäkerhet; INF303 Information Security; Information Systems; Informationssystem IS ;

    Sammanfattning : In the highly digitalised world in which we live today, information and information systems have become critical assets to organisations, and hence need to be safeguarded accordingly. In order to implement and work with information security in a structured way, an Information Security Management System (ISMS) can be implemented. LÄS MER

  5. 9. Aspects of adaptive mesh refinement in the spectral element method

    Författare :Nicolas Offermans; Philipp Schlatter; Ananias Tomboulides; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; NACA4412; periodic hill case.; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This thesis deals with the improvement of the efficiency of numerical simulations in computational fluid dynamics. Some of the limitations of current algorithms on future exascale supercomputers are addressed with the main goal of using adaptive mesh refinement for the simulation of turbulent and three-dimensional flows.

  7. 10. A Method for Designing Resilient Digital Business Ecosystems

    Författare :Chen Hsi Tsai; Janis Stirna; Jelena Zdravkovic; Irina Rychkov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital business ecosystem; method engineering; enterprise modelling; resilience; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : Organisations and companies are transforming their ways of conducting business by combining digitalisation and digital collaboration in digital business ecosystems (DBE) in order to be able to remain competitive in global markets. However, for companies and organisations to be able to take full advantage of such collaborative business constellations, several challenges, including the capture and coordination of information concerning individual DBE actors and various perspectives of a DBE and the design of resilience for a DBE, need to be addressed.
