1. Railway track dynamic modelling
Sammanfattning : The railway vehicles are an increasing mean of transportation due to, its reduced impact on environment and high level of comfort provided. These reasons have contributed to settle a positive perception of railway traffic into the European society. LÄS MER
2. Track circuits’ robustness : Modeling, measurement and simulation
Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER
3. Slab track optimisation considering dynamic train–track interaction
Sammanfattning : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. LÄS MER
4. Of Mice and MYC : Modelling Medulloblastoma
Sammanfattning : Brain tumours are the leading cause of cancer-related paediatric deaths, with medulloblastoma (MB) being the most common malignant paediatric brain tumour. MB is stratified into four major subgroups – WNT, SHH, Group 3, and Group 4, nomenclature defined by key pathways and drivers involved within each subgroup. LÄS MER
5. Simulation of vertical dynamic interaction between railway vehicle and slab 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
