2. 1. Efficient driving of CBTC ATO operated trains

   Author : William Carvajal Carreño; Paloma Cucala García; Antonio Fernández-Cardador; Lennart Söder; Rafael Palacios Hielscher; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; CBTC signalling system; ATO; Metro; Ecodriving; NSGA-II-F; pseudo-Pareto front; Tracking algorithm; Fuzzy parameters; Moving-block; Train Simulation.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

   Abstract : Energy consumption reduction is one of the priorities of metro operators, due to financial cost and environmental impact. The new signalling system Communications-Based Train Control (CBTC) is being installed in new and upgraded metro lines to increase transportation capacity. READ MORE

4. 2. Dephosphorization of magnetite fines : surface reactions, flotation kinetics and fuzzy logic application

   Author : Fenwei Su; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Abstract : The primary objective of the research work presented in this thesis is to investigate the influence of chemical and operational variables on the apatite flotation kinetics and to establish a suitable model using traditional method and fuzzy logic. The thesis consists of three parts, i.e. READ MORE

5. 3. Environmental Modeling and Uncertainty

   Author : Muhammad Sarfraz Iqbal; Dik van de Meent; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; multimedia fate modeling; uncertainty analysis; probability bounds analysis; fuzzy arithmetic; chemical safety assessment; REACH;

   Abstract : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. READ MORE

6. 4. Efficient Medical Volume Visualization : An Approach Based on Domain Knowledge

   Author : Claes Lundström; Anders Ynnerman; Hans Knutsson; Dirk Bartz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scientific Visualization; Medical Imaging; Computer Graphics; Volume Rendering; Transfer Function; Level-of-detail; Fuzzy Classification; Uncertainty Visualization; Virtual Autopsies; Medical engineering; Medicinsk teknik;

   Abstract : Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations.

7. 5. Interacting particle systems in varying environment, stochastic domination in statistical mechanics and optimal pairs trading in finance

   Author : Marcus M J Warfheimer; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interacting particle systems; contact process; randomly evolving environment; spin systems; Ising model; fuzzy Potts model; pairs trading; optimal stopping; contact process;

   Abstract : In this thesis we first consider the contact process in a randomly evolving environment, introduced by Erik Broman. This process is a generalization of the contact process where the recovery rate can vary between two values. The rate which it chooses is determined by a background process, which evolves independently at different sites. READ MORE
