Method for a structured identification of suitable safety and securing systems for Level Crossings [PDF]
, 2009 Safety and securing systems for level crossing have a long life time. Once a system reaches a life time when it is no longer conform to applicable regulations, it has to be modernized or replaced.

Automated Verification of Signalling Principles in Railway Interlocking Systems [PDF]
Electronic Notes in Theoretical Computer Science, 2009 AbstractIn this paper we present a verification strategy for signalling principles for the control of a railway interlocking system written in ladder logic. All translation steps have been implemented and tested on a real-world example of a railway interlocking system. The steps in this translation are as follows: 1.

A Biophysical Approach to the Design of Networks of Communication Systems
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Real-time traffic control in railway systems [PDF]
, 2011 Despite the constantly increasing demand of passengers and goods transport in Europe, the share of railway traffic is decreasing. One major reason appears to be congestion, which in turn results in frequent delays and in a general unreliability of the ...

Numerical Investigation of Bored Tunnelling Effects on Pile‐Supported Superstructures
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Tunnelling in urban environments can significantly affect existing buried structures such as pile foundations. However, the current understanding of how tunnelling‐induced ground movements influence the stability and serviceability of piles remains limited. This knowledge gap presents potential risks that must be addressed during tunnel design

Networks, EarlyView.ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.
