2. 11. Joint Pose and Radio Channel Estimation

   Author : Anders Mannesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis investigates the combination of pose and radio channel estimation. Pose is the knowledge of the position and orientation of a device whereas the radio channel describes the transmission medium between radio transmitters and receivers. READ MORE

4. 12. Modeling and Control for Improved Predictability of Cloud Applications

   Author : Tommi Berner; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Applied control; Cloud computing; Queuing theory;

   Abstract : Cloud computing has emerged as a key technology in the latest decade and continues to be applied to manage the computing needs of new domains. As a result, the requirements on predictable behavior in the cloud increase, thus the hosted applications need to be recognized as both fault-tolerant and responsive even under difficult conditions.

5. 13. On the Characterization and Generation of Flow Marks on Polymeric Surfaces

   Author : Giovanna Iannuzzi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tiger stripes; surface defects; rheological properties; injection moulding; polymer processing; flow marks;

   Abstract : Polymer-based materials are widely used in the automotive industry for producing vehicle parts, for instance car bumpers, dash boards etc. A common manufacturing process for such components is injection moulding. READ MORE

6. 14. Computational Railway Dynamics - Integrated Train - Track - Subgrade Modeling and Simulations

   Author : Håkan Lane; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The primary objective of the thesis has been to extend the capabilities for computational modeling, prediction and simulation of the elastic response of the train, track structure and soil in railway systems. The industrial background is the high level of ground borne vibrations reported from citizens as a consequence of train traffic (in particular from high speed trains) in several Swedish locations.

7. 15. Rotordynamic Analysis with Special Reference to Composite Rotors and Internal Damping

   Author : Håkan Wettergren; Jörgen W. Lund; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The present doctoral thesis is concerned with three different rotordynarnic applications; composite rotors, internal damping and microslip in a turbine generator. When a composite shaft has an imperfection, such as differences in the filament winding angle, the eigenfrequencies of the non-rotating shaft depend only on the material stiffness. READ MORE
