2. 1. The isostatic pressure processing of high Tc superconductors and their properties

   Author : John Niska; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

   Abstract : The high Tc superconductors are highly anisotropic, ceramic materials which makes it difficult to sinter them at atmospheric pressure to full density. High porosity is detrimental to their mechanical and electrical properties, so the use of isostatic pressures was used to give higher density materials with improved properties. READ MORE

4. 2. Toward a reliability framework for the observational method

   Author : Johan Spross; Stefan Larsson; Fredrik Johansson; Rasmus Müller; John Harrison; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; observational method; Eurocode 7; structural safety; reliability analysis; dam safety; Bergmekanik; observationsmetoden; Eurokod 7; sannolikhetsbaserad dimensionering; dammsäkerhet; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Constructing sustainable structures in rock that satisfy all predefined technical specifications requires rational and effective construction methods. When the geotechnical behaviour is hard to predict, the Euro­pean design code, Eurocode 7, suggests application of the observational method to verify that the performance is acceptable. READ MORE
