The Victor-Purpura spike train metric has recently been extended to a family of multineuron metrics and used to analyze spike trains recorded simultaneously from pairs of proximate neurons. The metric is one of the two metrics commonly used for quantifying the distance between two spike trains; the other is the van Rossum metric. Here, we suggest an extension of the van Rossum metric to a multi...

background: national transport commission (ntc) classifies train driving as a high-level safety critical job. objective: to assess fitness-for-work among train drivers in yazd, central iran. methods: we evaluated 152 train drivers for their fitness for duty. the results were then compared with ntc guidelines. results: 63.8% of subjects were fit for duty, 34.2% fit subject to review, and 2.0% we...

To obtain the appropriate number of layers for spatial multiplexing transmission on a high speed train equipped with moving relay nodes (MRN) cooperating with each other, the rank indicator (RI) is required. The conventional methods for calculating the RI have high levels of computational complexity and to dynamically obtain the RI based on the channel conditions require multiple times the comp...

Nowadays, railways are confronted with numerous pressing problems, including capacity optimization, energy conservation, cost reduction and improving customer satisfaction. While the traditional railway is a very safe means of transportation, it still cannot meet all these requirements. Hence there are high interests in two available systems to overcome these challenges: Traffic Management Syst...

In recent decades, the demand for rail transport has been growing steadily and faces a double problem. Not only must capacity be increased, but also more flexible service is needed to meet real demand. Both objectives can achieved through virtual coupling (VC), which an evolution of current moving block systems. Trains under VC run much closer together, forming what called virtually coupled tra...
