  1. 1. Robust design : Accounting for uncertainties in engineering

    Författare :David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  3. 2. Risk-based ship security analysis : a decision-support approach

    Författare :Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Rolf Skjong; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; survivability; uncertainty analysis; militära fartyg; sjöröveri; riskanalys; sjöfartsskydd; överlevnadsförmåga; Försvarssystem; Military Technology;

    Sammanfattning : The protection of shipping does not come without hazards and threats for military forces, individual civilian ship operators and crews. With particular focus on security threats, this thesis is about how to prepare for such operations without introducing unnecessary risks, i.e., supporting conscious risk-taking related to ship security.

  4. 3. Robust analysis of uncertainty in scientific assessments

    Författare :Ivette Raices Cruz; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; expert knowledge; robust Bayesian analysis; scientific assessments; subjective probability; uncertainty analysis;

    Sammanfattning : Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. LÄS MER

  5. 4. Survivability control using data-driven approaches and reliability analysis for wave energy converters

    Författare :Zahra Shahroozi; Jens Engström; Malin Göteman; Lars Johanning; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power maximization; prediction horizon; extreme wave conditions; wave tank experiment; numerical WEC-Sim analysis; reliability analysis; statistical methods; environmental design load; fatigue analysis; statistical methods; survivability analysis; neural network methods;

    Sammanfattning : Wave energy, with five times the energy density of wind and ten times the power density of solar, offers a compelling carbon-free electricity solution. Despite its advantages, ongoing debates surround the reliability and economic feasibility of wave energy converters (WECs). LÄS MER

  7. 5. Aeroelastic Concepts for Flexible Wing Structures

    Författare :Sebastian Heinze; Ulf Ringertz; Bengt Winzell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active aeroelasticity; flexible wings; aeroelastic control; design; experiments; testing; analysis; robust; uncertainty; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis summarizes investigations performed within design, analysis and experimental evaluation of flexible aircraft structures. Not only the problems, but rather the opportunities related to aeroelasticity are discussed. LÄS MER
