16. Functional nanocomposites for advanced fuel cell technology and polygeneration
Sammanfattning : In recent decades, the use of fossil fuels has increased exponentially with a corresponding sharp increase in the pollution of the environment. The need for clean and sustainable technologies for the generation of power with reduced or zero environment impact has become critical. LÄS MER
17. Thermally Induced Fracture Performance of Asphalt Mixtures
Sammanfattning : A major distress mode in asphalt pavements is low temperature cracking, which results from the contraction and expansion of the asphalt pavement under extreme temperature changes. The potential for low temperature cracking is an interplay between the environment, the road structure and importantly the properties of the asphalt mixture. LÄS MER
18. Simulation of dynamic interaction between train and turnout
Sammanfattning : .... LÄS MER
19. Electromagnetic noise generated in the electrified railway propulsion system
Sammanfattning : The electromagnetic compatibility (EMC) problem in the railway propulsion system is a significant safety issue of high concern. The problems can be caused by any part of the propulsion system as well as any combination of the sub systems. Simulation is a fast economical way to understand the system and to predict the EMC performance. LÄS MER
20. Dynamic Train-Turnout Interaction – Mathematical Modelling, Numerical Simulation and Field Testing
Sammanfattning : Two models for simulation of dynamic interaction between train and turnout are developed. The first one is derived using a commercial software for dynamics of multi-body systems. LÄS MER
