2. 1. NMR Studies of Inclusion Compounds

   Author : Sahar Nikkhou Aski; Jozef Kowalewski; Pierre Mutzenhardt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; 13C spin relaxation; PFGNMR; Kinetics; Correlation time; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Abstract : This thesis presents the application of some of the NMR methods in studying host-guest complexes, mainly in solution. The general focus of the work is on investigating the reorientational dynamics of some small molecules that are bound inside cavities of larger moieties. READ MORE

4. 2. Chloromethane Complexation by Cryptophanes : Host-Guest Chemistry Investigated by NMR and Quantum Chemical Calculations

   Author : Zoltan Takacs; Jozef Kowalewski; Mikael Akke; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host–guest complexes; inclusion phenomenon; cryptophanes; NMR; kinetics; activation energy; dipolar interaction; exchange; quantum chemical optimization; calculated chemical shifts; NOESY; cavity size; fysikalisk kemi; Physical Chemistry;

   Abstract : Host–guest complexes are widely investigated because of their importance in many industrial applications. The investigation of their physico–chemical properties helps understanding the inclusion phenomenon. The hosts investigated in this work are cryptophane molecules possessing a hydrophobic cavity.

5. 3. Topics in Modeling, Control, and Implementation in Automotive Systems

   Author : Magnus Gäfvert; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Abstract : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. READ MORE

6. 4. Simulation of deformable objects transported in fluid flow

   Author : Arash Alizad Banaei; Luca Brandt; Markus Holzner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Abstract : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.

7. 5. 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.
