11. A study of the effects of winterclimate and atmospheric icing onhigh-speed passenger trains
University essay from Umeå universitet/Institutionen för matematik och matematisk statistikAbstract : Harsh winter climate causes various problems for both the public andprivate sector in Sweden, especially in the northern part and the railway industryis no exception. This master thesis project covers an investigation of the eects ofthe winter climate and a phenomena called atmospheric icing on the performance ofthe train in a region called the Botnia-Atlantica region.

12. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation
University essay from KTH/Bro- och stålbyggnadAbstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

13. Maglev deployment in winter climate
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : As of year 2020, maglev train systems are not in service in areas with harsh winter climate. Compared to conventional railway, the technology is relatively new and untested in conditions of low temperatures, icing and snow. READ MORE

14. Soil-Structure Interaction Analysis of Portal Frame Railway Bridges : Numerical Analysis of Two Case Study Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : This thesis concerns dynamic Soil-Structure Interaction (SSI) analysis of portal framerailway bridges. Dynamic problems are common for bridges used for high speedrailway traffic. The passing trains induce harmonic loads on the bridges causingvibration amplitudes that may cause damage to the bridge structures and userdiscomfort. READ MORE

15. Machine Learning – Based Dynamic Response Prediction of High – Speed Railway Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : Targeting heavier freights and transporting passengers with higher speeds became the strategic railway development during the past decades significantly increasing interests on railway networks. Among different components of a railway network, bridges constitute a major portion imposing considerable construction and maintenance costs. READ MORE
