STOCHASTIC MODELING OF DELAY PROPAGATION IN TRANSPORTATION SYSTEMS FOR CAPACITY OPTIMIZATION

The minimal headway for virtually coupled (VC) freight trains operating under stochastic timetable disturbances on the Trans-Siberian Railway is investigated. By analyzing empirical data from the Oy-Mos section, we identify distinct delay distribution patterns for regular freight (Erlang), heavy-haul (chi-square) and e...

Dysprosium(III) Sulfate Dy2(SO4)3: Crystal and Electronic Structure, Thermal Expansion, Thermochemistry, Magnetic and Optical Properties.

Dy2(SO4)3 is shown to exhibit negative thermal expansion (NTE) in all three crystallographic directions, suggesting that rare earth sulfates may serve as a novel platform for 3D NTE materials. High-temperature x-ray diffraction (453-703 K) reveals a NTE volume coefficient of αV = -18.27(7)·10-6 K-1, attributed to aniso...
