2. 1. The flow of pulp suspensions

   Author : Helena Fock; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp suspensions; Velocity profile; Concentration profile; Wall layer; Particle image velocimetry; Flow behaviour; Computational fluid dynamics; Ultrasound velocity profiling;

   Abstract : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. READ MORE

5. 3. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

   Author : Roger Enblom; KTH; []
   Keywords : contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. READ MORE

6. 4. Seismic-Reflection and Seismic-Refraction Imaging of the South Portuguese Zone Fold-and-Thrust Belt

   Author : Cedric Schmelzbach; Christopher Juhlin; Laust Pedersen; Hans Thybo; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Dip-moveout; Prestack time migration; Crooked-line geometry; Traveltime tomography; Inversion; Seismic velocity; IBERSEIS profile; Variscan orogeny; Iberian Pyrite Belt; Geofysik; Earth sciences; Geovetenskap;

   Abstract : The South Portuguese Zone (SPZ), which host world-class massive sulphide deposits, forms the southern fold-and-thrust belt of the Iberian Variscan orogeny. This thesis focuses on seismic-reflection and seismic-refraction processing efforts on a subset of the IBERSEIS deep seismic-reflection data set aiming at resolving the SPZ upper crust in high resolution.

7. 5. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

   Author : Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

   Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE
