2. 16. Diffusion MRI with generalised gradient waveforms : methods, models, and neuroimaging applications

   Author : Deneb Boito; Evren Özarslan; Magnus Herberthson; Anders Eklund; Ida Blystad; Frederik Laun; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Diffusion MRI; Microstructure; Brain; White matter; Microscopic anisotropy; Constrained optimisation;

   Abstract : The incessant, random motion of water molecules within biological tissues reveals unique information about the tissues’ structural and functional characteristics. Diffusion magnetic resonance imaging is sensitive to this random motion, and since the mid-1990s it has been extensively employed for studying the human brain. READ MORE

4. 17. Models and Methods for Analysis and Improvementof Physical Work Environments

   Author : Linda Rose; Roland Örtengren; Mats Ericson; Bengt Nordgren; Per Odenrick; Division of Human Factors Engineering Department of Product abd Production Development Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ergonomics; economics; risk management; work-related personal injuries; construction industry; fatigue reactions; EMG; endurance; recovery; modelling.;

   Abstract : The aim of this thesis concerning work-related personal injuries was to obtain knowledge bases for two purposes. The first was to develop a model, the Ergo-Index, for use when comparing work situations regarding ergonomics and time aspects and choosing the most favourable working method. READ MORE

5. 18. Ride comfort and motion sickness in tilting trains

   Author : Johan Förstberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tilting train; Ride comfort; Motion sickness; Simulator; Experiments;

   Abstract : This thesis presents a systematic study of human responses to different motions and strategies of car body tilt control regarding ride comfort, working/reading ability and motion sickness on high-speed tilting trains. Experiments with test subjects were performed in a tilting train on curved track as well as in a moving vehicle simulator. READ MORE

6. 19. Tilting trains : Enhanced benefits and strategies for less motion sickness

   Author : Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; Vehicle engineering; Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

   Abstract : Carbody tilting is today a mature and inexpensive technology that allows higher train speeds in horizontal curves, thus shortening travel time. This doctoral thesis considers several subjects important for improving the competitiveness of tilting trains compared to non-tilting ones. READ MORE

7. 20. A Mathematical and Experimental Study of Inclusion Behaviour at a Steel-Slag Interface

   Author : Jenny Wikström; Pär Jönsson; Lauri Holappa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; CSLM experiments; agglomeration; physical properties; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

   Abstract : The aim of this thesis work is to increase the knowledge of inclusion behavior at the steel-slag interface by mathematical modeling and in-situ Confocal Scanning Laser Microscope experiments. Mathematical models based on the equation of motion predicting liquid and solid inclusion behavior was first investigated. READ MORE
