QNS&L wheel-rail optimization strategy

2006
QNS&L, Canada has undertaken a long-term plan to improve its track maintenance process including the development of a long-term wheel-rail interaction strategy. The plan included an assessment of the annual rail replacement requirements, better welding procedures, improved gauge-face lubrication, profile grinding of the rails, preventive reprofiling of

Classical waves on nonlinear lattices. II. Qn

Journal of Mathematical Physics, 2009
Exact analytical solutions are found for classical vibrations of nonlinear oscillators with higher powers of spring constants, such as Q6 and Q8. The solutions are based on a new type of elliptic function that has been created to solve these problems.

NMR and QNS investigation of molecular liquids

Electrochimica Acta, 1988
Abstract NMR relaxation results are summarized for 18-crown-6 ether, for water (H172O and D2O) in dimethylsulfoxide, for tetrahydrofuran and for methyl iodide in the corresponding clathrate hydrates. Rotational diffusion coefficients are derived for the crown ether.
