Influences of Railway Track Geometry Parameters on Ground-Borne Vibration
One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...
متن کاملTamping Planning in Railway Maintenance
Optram is a computer software for evaluation of track geometry quality data, used as a decision support in planning and follow-up of tamping maintenance for Swedish railways. The software was introduced at the Swedish Transport Administration year 2009 but has not reached the intended number of users. The purpose with this thesis is to suggest how Optram can be improved as a decision support in...
متن کاملPower Optimal Opportunistic Scheduling
In this paper, we propose a power optimal opportunistic scheduling scheme for a multiuser single hop Time Division Multiple Access (TDMA) system. We formulate the problem of minimizing average transmission power with different minimum rate constraints for individual users. We suggest a stochastic approximation based scheme to implement the policy and argue the convergence of this algorithm. Fin...

متن کاملHeuristic based track maintenance scheduling optimisation
The maintenance of railway track is highly relevant for the service quality and safety. This task demands huge technical and human resources. Therefore an optimal deployment of the available resources is crusial for the cost-effectiveness of railway operation. Furthermore, the track geometry maintenance activities need to be planned up to two years in advance. For this reason the French railway...
