Time-reversal inside a granular suspension to probe ultrasound diffusion by Yamil Abraham, Bart A. van Tiggelen, Nicolas Benech, Carlos Negreira, Xiaoping Jia, Arnaud Tourin

“…A short pulse is emitted by a single array element and the TRM records the resulting ultrasonic field, composed of a coherent ballistic wave followed by a diffuse coda wave. When the entire coda is time-reversed and re-emitted from the TRM, the wave refocuses at the original source with a focal spot size that decreases with the inverse of the TRM depth, consistent with diffusive transport. …”

INFLUENCE OF THE SPATIAL ARRANGEMENT OF SEISMIC DETECTORS ON THE ACCURACY OF EARTHQUAKE HYPOCENTRE DETERMINATION by T. G. Aslanov, Кh. J. Magomedov, U. A. Musayeva, Кh. Y. Tagirov

“…To determine the coordinates of the seismic focus of an earthquake with a minimum margin of error with the use of an optimal selection of seismic sensors. Method. Seismic wave velocity data, relying on the time discrepancies between the registering of seismic waves on the seismic sensor and the defined error in determining the time difference, were used to identify errors in the location of an earthquake's hypocenter depending on the respective positions of three seismic sensors. …”

Sensitivity Analysis of Mooring Chain Fatigue of Floating Offshore Wind Turbines in Shallow Water by Jiahao Chen, Ziwei Yin, Can Zheng, Yan Li

“…The mooring fatigue calculated using turbulent wind spectrum was greater than that calculated using steady wind. In contrast, waves are the main source of mooring fatigue, and the second-order wave force has an undeniable impact on the mooring fatigue of a semi-submersible floating offshore wind turbine, which accounts for approximately 26% of wave-induced mooring fatigue. …”
