The technology in intelligent terminals enables communication from the process level to the SCS, substation, SCADA/EMS, and the network levels. Any function and parameter can be programmed and changed remotely. Automatic sequences can be included on bay and substation levels utilising the SCS. In addition, with serial communication, binary inputs, and user programming, it is possible to adapt f...

In this chapter, power losses and mass of optimally designed Sivs. SiC-based isolated DC-DC converters are compared in quantitative terms. To that end, an adapted version of a computer-aided design tool, previously published by the authors, is used. The database of the existing tool was completed with new wide band gap semicon‐ ductor devices currently available from manufacturers. The results ...

Railway environments cannot be away from the current evolution of public communication systems. The Long Term Evolution (LTE) mobile communication system is considered to be the natural evolution for current Global System for Mobile Communications Railways (GSM-R). LTE all IP networking technology plays a key role for the integration and convergence of heterogeneous networks and services, both ...

This paper studies the modeling theories and simulation methods for railway transportation system. The railway transportation system is a typical temporal-spatial dynamic system. Recently the method with temporal-spatial computation characteristics, Cellular Automata, is often used for road traffic flow research, but it’s homogeneity restricting make it impossible to modeling railway transporta...

Railway maintenance planners require a predictive model that can assess the railway track geometry degradation. The present paper uses a hierarchical Bayesian model as a tool to model the main two quality indicators related to railway track geometry degradation: the standard deviation of longitudinal level defects and the standard deviation of horizontal alignment defects. Hierarchical Bayesian...

Railway ballast tamping operation is employed in order to restore the geometry of railway track distorted by train traffics. In this paper, based on analysis of tamping principle, the discrete element analysis model of railway ballast is created using the discrete element method, numerical simulations are performed to study the change of railway ballast compactness during tamping process. This ...
