2. 1. Marine Propeller Optimisation - Strategy and Algorithm Development

   Author : Florian Vesting; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cavitation; artificial neural network; RANS; Kriging; potential flow; genetic algorithm; constrained optimisation; PSO; marine propeller;

   Abstract : Recent trends in the shipping industry, e.g., expanded routing in ecologically sensitive areas and emission regulations, have sharpened the perception of efficient propeller designs. Currently, propeller efficiency, estimated fuel consumption and, more often, propeller-radiated noise are parameters that steer the business Zeitgeist. READ MORE

4. 2. Burden of disease in psoriasis and psoriatic arthritis. Occurrence, healthcare use, costs and health outcomes

   Author : SOFIA LÖFVENDAHL; Lund Ortopedi; []
   Keywords : ;

   Abstract : Psoriasis (PSO) and psoriatic arthritis (PsA) are two related chronic inflammatory diseases. A proportion of people with PSO also develop PsA. PSO and PsA seem to have multiple impacts; from the health and well-being of the individual; to the need for healthcare resources for disease management; to the loss of productivity. READ MORE

5. 3. Designing Mathematics Lessons Using Japanese Problem Solving Oriented Lesson Structure : A Swedish case study

   Author : Yukiko Asami-Johansson; Christer Bergsten; Iiris Attorps; Heidi Strømskag; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This licentiate thesis is concerned with applying the Japanese problem solving oriented (PSO) teaching approach to Swedish mathematics classrooms. The overall aim of my research project is to describe and investigate the viability of PSO as design tool for teaching mathematics. READ MORE

6. 4. Event Detection in Eye-Tracking Data for Use in Applications with Dynamic Stimuli

   Author : Linnéa Larsson; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This doctoral thesis has signal processing of eye-tracking data as its main theme. An eye-tracker is a tool used for estimation of the point where one is looking. Automatic algorithms for classification of different types of eye movements, so called events, form the basis for relating the eye-tracking data to cognitive processes during, e.g. READ MORE

7. 5. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

   Author : Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

   Abstract : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.
