1. 16. Congestion Charging in Urban Networks : Modelling Issues and Simulated Effects

   Författare :Ida Kristoffersson; Leonid Engelson; Otto Anker Nielsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Modelling; Congestion Charging; Departure Time Choice; Dynamic Traffic Simulation; Welfare Effects; Equity;

   Sammanfattning : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. LÄS MER

3. 17. Static and Dynamic Modelling of the Drying Section of a Paper Machine

   Författare :Magnus Karlsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pappers- och massateknik; Modelling; Wood; Paper; Multi-Cylinder; Simulation; Control; Steam; Air; Dew Point; Moisture Gradients; pulp and paper technology; Pressure Gradients;

   Sammanfattning : The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. LÄS MER

4. 18. Simulation of vertical dynamic interaction between railway vehicle and slab track

   Författare :Emil Aggestam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transition zones; genetic algorithm; dynamic vehicle–track interaction; Slab track; modelling; ballasteless track;

   Sammanfattning : The usage of slab track for high-speed railway lines has increased in recent decades. In Sweden, the building of new railway lines for higher speed and the selection of track design for such lines are currently being debated. LÄS MER

5. 19. Dynamic Modelling of Emulsification in High-Pressure Homogenizers

   Författare :Andreas Håkansson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Population Balance Equations; Emulsification; High-Pressure Homogenization; Computational Fluid Dynamics; Mathematical Modelling.;

   Sammanfattning : Different approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended papers to their alternatives and previous suggestions. LÄS MER

7. 20. Dynamic Modelling of Transit Operations and Passenger Decisions

   Författare :Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

   Sammanfattning : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. LÄS MER
