This case report focuses on the findings in what appeared to be a planned complex pistol head shot and train suicide. The post mortem computed tomography (PMCT) scan this instance yielded two interesting skull fragments among many of highly fragmented body head. These fragments, based initial resolution, show consistent with firearm Upon reconstruction higher resolution data, necessary discrimi...

Energy consumption for multiple trains on the urban subway line is predominantly affected by the operation strategy. This paper proposed an energy-saving operation strategy for multiple trains, which is suitable for various line conditions and complex train schedules. The model and operation modes of the strategy are illustrated in detail, aiming to take full use of regenerative braking energy ...

the main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. therefore, railway track desig...

The identification of risky areas along the railroad in the context of a railway system is a complex problem. A railway system is spatially and functionally distributed; its subsystems have a high degree of autonomy, and are in constant interaction with each other and with their geographic environment. In order to identify risky areas in the vicinity of rock falls zones we need to model and sim...

Almost all trains have to run according a schedule. One exception may be some freight trains which may start at a random time. Unfortunatly, for some reasons, some minor problems occur and lead to have delays. Due to limited ressources available (tracks, cars,. . . ), a small problem can lead to a chain of delays. To monitor the traffic and take decisions are the main goals of the train dispatc...
