The safety analysis of interlocking railway systems involves verifying collision and derailment freedom. In this paper we propose a structured way of refining track plans, in order to expand track segments so that they form collections of track segments. We show how the abstract model can be model checked to ensure the safety properties, which must also hold in the corresponding concrete track ...
Perceptual derailment and confabulations often appear in a subtle way, being processes addressable to the field of inner world, conditioning the diagnostic process. The present clinical report aims to explore the role of Rorschach projective technique in eliciting processes otherwise unsearchable. Psycho-diagnostics data were compared to other psychometric tests such as the MMPI-2 (Minnesota Mu...
This paper reports the first results of a new interface between the multi-body simulation software SIMPACK Rail and Kalker’s wheel-rail contact software CONTACT. The main benefit is in the more accurate distributions of shear stress and micro-slip in the contact area, that together form the primary inputs to wear calculations. Further benefits of the interfacing reside in the ability to perform...
Abstract With the rapid development of high-speed railways around globe, safety vehicles running on bridges during earthquakes has been paid more attention to. In design railway bridges, in addition to ensuring bridge structure earthquake, vehicle should also be ensured. Previous studies have focused detailed analysis derailment proposing complex numerical algorithms for wheel–rail contact as w...
Libon et al. (2010) provided evidence for three statistically determined clusters of patients with mild cognitive impairment (MCI): amnesic (aMCI), dysexecutive (dMCI), and mixed (mxMCI). The current study further examined dysexecutive impairment in MCI using the framework of Fuster's (1997) derailed temporal gradients, that is, declining performance on executive tests over time or test epoch. ...
