JACOBSTHAL RECURRENT NUMBERS AS A PLATFORM FOR TRANSFORMATIONS K·Q±1

The paper investigates the role of Jacobsthal recurrent numbers in forming statistical patterns within the model of the natural number hypothesis q ϵ ℕ in the general problem of the form κ⋅q±1, where κ=1,3,5,…. A novel model is proposed for structuring the set of natural numbers as sequences of the form θ⋅2ⁿ, where the parameter θ takes odd values 1,3,5,…, and n is a natural number starting from zero.

Calculation model for the evaluation of tired defect development in the freight wagon side frame

The reliability and safe operation of mechanical elements of rail transport is an important and relevant scientific and technical issue since high-loaded units and elements of its chassis are exposed to prolonged operation and their failure can lead to damage with catastrophic consequences. To prevent the possible failure of such objects, there is a necessity for a reliable estimation of their residual life.
