INFLUENCE OF SOIL PARAMETERS ON THE VALUE OF THE MODULUS OF THE VERTICAL TRACK ELASTICITY
Science and Transport Progress, 2003 The necessity of updating of values of the vertical module of a track elasticity is proved, by taking info account of a sort of the subarade soil its state both thickness of a ballast layer and its state. The numerical rating of parameters influencing the module of the track elasticity is given.

Optimising low acoustic impedance back-fill material wave barrier dimensions to shield structures from ground borne high speed rail vibrations [PDF]
, 2013 Ground borne vibrations generated due to high speed train passage can cause undesirable effects on the nearby environment. One approach to mitigate vibration levels is to use "wave barriers", however their installation cost may be very high.

Detecting and tracking eddies in oceanic flow fields: a Lagrangian descriptor based on the modulus of vorticity [PDF]
Nonlinear Processes in Geophysics, 2016 Abstract. Since eddies play a major role in the dynamics of oceanic flows, it is of great interest to detect them and gain information about their tracks, their lifetimes and their shapes. We present a Lagrangian descriptor based on the modulus of vorticity to construct an eddy tracking tool.
