Impacts of Wheel–rail at Railway Turnouts
Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...

متن کاملA Method of Designing Railway Signalling System Based on RAMS Indicators
Shigeto HIRAGURI ȁSince the IEC published RAMS Standard in 2002 objective to railways, its importance and an impact of the standard to Japan have been conspicuous. On the contrary, new various train control systems based on information technology are under active development. Considering such situations, we assume that it is essential to establish a method to design railway-signalling systems, ...
متن کاملCoordinations and Turnouts in Large Elections
We present a stochastic model of coordination in turnout games with boundedly rational voters. In each period a randomly selected voter receives information about current play through noisy polls and then, based on this information, forms expectations about the current configuration of play and chooses a best response. We prove the existence of a unique limiting distribution for the process and...
متن کاملCommunity Size, Heterogeneity and Voter Turnouts
Numerous studies have found a negative relationship between the closeness of an election, the size of the electorate and voter turnout. It is often claimed that this relationship supports the rational voter hypothesis, with closeness and size proxying for the decisiveness of a vote. We offer a different interpretation. Larger communities are more heterogeneous than smaller ones, and turnouts ar...
