Electronic Track Map Building for Satellite-based High Integrity Railway Train Positioning
The concept of electronic track map has been introduced and researched in many satellitebased railway train positioning and location-based railway systems. It should characterize the railway tracks and their key objects and facilities with a satisfied accuracy and completeness. Based on the application requirements, design and building of the electronic track maps should be in accordance with t...
متن کاملThree-Dimensional Dynamic Analyses of Track-Embankment-Ground System Subjected to High Speed Train Loads
A three-dimensional finite element model was developed to investigate dynamic response of track-embankment-ground system subjected to moving loads caused by high speed trains. The track-embankment-ground systems such as the sleepers, the ballast, the embankment, and the ground are represented by 8-noded solid elements. The infinite elements are used to represent the infinite boundary condition ...
متن کاملThree-dimensional Accurate Positioning Algorithm based on Wireless Sensor Networks
Three-dimensional accurate positioning algorithm, using RSSI-based (Received Signal Strength Indication) positioning method, which constructs an attenuation model of wireless signal between beacon node and unknown node in three-dimensional space, and compensates for the loss of wireless signal on the basis of their material, thickness and other factors when there are obstacles or walls being in...
متن کاملSingle Track Train Scheduling
In this work we consider the Single Track Train Scheduling Problem. The problem consists in scheduling a set of trains from opposite sides along a single track. The track passes intermediate stations and the trains are only allowed to pass each other at those stations. This problem has a close relation to minimizing the makespan in a job shop scheduling problem with two counter routes and no pr...
متن کاملRobotic positioning device for three-dimensional printing
Additive manufacturing brings a variety of new possibilities to the construction industry, extending the capabilities of existing fabrication methods whilst also creating new possibilities. Currently three-dimensional printing is used to produce small-scale objects; largescale three-dimensional printing is difficult due to the size of positioning devices and machine elements. Presently fixed Co...
