Rabinowitz and Wagon (in American Mathematical Monthly 102(3):195–203, 1995) present a spigot algorithm for computing the digits of π. A spigot algorithm yields its outputs incrementally, and does not reuse them after producing them. Their algorithm is inherently bounded ; it requires a commitment in advance to the number of digits to be computed, and in fact might still produce an incorrect la...

The results of the analysis delivery time loaded wagons were determined by mathematical-statistical methods. wagon shipment was considered in example a with transport distance 200, 650, 1000 km processing process based on method. According to law normal distribution, accuracy approximation is V.I. In an examination using Romanovsky criterion, it proved that would be taken into account future. p...

Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...
