1. 26. Flight Test System Identification

   Författare :Roger Larsson; Martin Enqvist; Lennart Ljung; Roy Smith; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. LÄS MER

3. 27. Testing for Rationality, Separability and Efficiency

   Författare :Per Hjertstrand; Nationalekonomiska institutionen; []

   Sammanfattning : This thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. LÄS MER

4. 28. BACK TO ONESELF Sensory Motor Learning applied in patients with nonspecific chronic low back pain

   Författare :Christina Schön-Ohlsson; Göteborgs universitet; []
   Nyckelord :Chronic nonspecific low back pain; Sensory Motor Learning; SML; Posturo-Locomotion-Manipulation PLM test; Qualitative method; Focus group study; Health promotion; Feldenkrais method; Exercise therapy;

   Sammanfattning : Back pain is an endemic problem affecting one in five adults every year. Even though only 10 % of all cases of back pain become chronic it is one of the largest health problems in industrialized societies. LÄS MER

5. 29. Rapid Aerodynamic Method for Interacting Sails

   Författare :Karolina Malmek; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lifting line method; wind-assisted propulsion; sail–sail interaction; wingsail; wind propulsion system;

   Sammanfattning : Rapid performance prediction tools are required for the evaluation, optimization, and comparison of different wind propulsion systems (WPSs). These tools should capture viscous aerodynamic flow effects in 3D, especially the maximum propulsion force, stall angles and interaction effects between the lift-generating units. LÄS MER

7. 30. Aspects of adaptive mesh refinement in the spectral element method

   Författare :Nicolas Offermans; Philipp Schlatter; Ananias Tomboulides; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; NACA4412; periodic hill case.; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : This thesis deals with the improvement of the efficiency of numerical simulations in computational fluid dynamics. Some of the limitations of current algorithms on future exascale supercomputers are addressed with the main goal of using adaptive mesh refinement for the simulation of turbulent and three-dimensional flows.
