2. 1. Numerical and Experimental study of shock boundary layer interaction in unsteady transonic flow

   Author : Olivier Bron; KTH; []
   Keywords : Shock Boundary Layer Interaction; Shock Motion; Unsteady Flows; Nozzle Flows; Potential Interaction; Back Pressure Perturbations;

   Abstract : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. READ MORE

4. 2. Neuromechanical control of the spine

   Author : Paul Hodges; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Control of the spine is complex. The spine is inherently unstable and dependent on the contribution of muscles. Yet there is considerable redundancy in the motor system with many muscles that act on the trunk. READ MORE

5. 3. On Parameter Identification for Better Predictions of Dam Behaviour

   Author : Jasmina Toromanovic; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

   Abstract : Numerical modelling is often needed as a tool to predict the behaviour and assess the safety of dam structures. Embankment dam structures analyses are quite complex and potential failures are hazardous. Predictions of dam behaviour by numerical modelling rely on knowledge about the mechanical properties of the materials the dam is constructed with. READ MORE
