2. 1. Stainless steel plasticity : material modelling and structural applications

   Author : Anders Olsson; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. READ MORE

4. 2. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

   Author : Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

   Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

5. 3. Plastic behaviour of steel : experimental investigation and modelling

   Author : Jonas Gozzi; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. READ MORE

6. 4. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

   Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

   Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

7. 5. Bracing of steel bridges during construction; theory, full-scale tests and simulations

   Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

   Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.
