2. 1. Failure diagnostics using support vector machine

   Author : Yuan Fuqing; Thomas Lindblad; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Failure diagnostics is an important part of condition monitoring aiming to identify incipient failures in early stages. Accurate and efficient failure diagnostics can guarantee that the operator makes the correct maintenance decision, thereby reducing the maintenance costs and improving system availability. READ MORE

   Abstract : The effects of climate change are already being felt today, and future effects, which will be determined by the readiness and resolve of today’s world leaders, are fraught with high levels of complexity, uncertainty, ambiguity, and transboundary effects – characteristics of systemic risk. Since climate change is seen as a threat multiplier, the risks that might be impacted by climate change, such as floods and dam failure, will be affected by systemic risk characteristics as well.

5. 3. Thermo-mechanical Assessment of Reactor Pressure Vessels of Light Water Reactors During Severe Accidents

   Author : Hongdi Wang; Walter Villanueva; Sevostian Bechta; Weimin Ma; Artem Kulachenko; Michael Fitzpatrick; KTH; []
   Keywords : Severe accident scenario; reactor pressure vessel; in-vessel melt retention; failure analysis; finite element analysis; validations; Scenario för svåra haverier; reaktortank; in-vessel retention; feleffektsanalys; Finite Element Analyser; validering; Physics; Fysik;

   Abstract : The reactor pressure vessel (RPV) is one of the crucial safety barriers designed to isolate the reactor core, safeguarding against potential radioactive releases into the environment during a severe accident. The assessment of RPV behaviour and its failure is necessary to predict the characteristics of melt release into the reactor pit and succeeding ex-vessel accident progression. READ MORE

6. 4. On conceptual design reliability : an approach for identification of potential failures

   Author : Micael Derelöv; Linköpings universitet; []
   Keywords : Conceptual Design; Potential Failure; Evaluation; Reliability; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis is the result of research in the area of Evaluation and Decision-Making in the Design Process. It examines how to support and facilitate the evaluation activities in the design process in order to create a more solid foundation on which to base design decisions. READ MORE

7. 5. Analytical and numerical approaches to estimate peak shear strength of rock joints

   Author : Francisco Ríos Bayona; Stefan Larsson; Fredrik Johansson; Diego Mas Ivars; José Muralha; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joint; Shear strength; Failure criterion; Numerical shear tests; Bergsprickor; Skjuvhållfasthet; Brottkriterium; Numeriska skjuvförsök; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. READ MORE
