Summary: This study proposes a novel approach based on the S-transform for generating spectrum-matched records of a given seed record. The approach adjusts the amplitude of the ST coefficients in the S-transform domain to match a prescribed response spectrum, while retaining the visual characteristics of the records.

Summary: The aim of this study was to quantify and compare the speed and acceleration of ball-carriers and tacklers during the pre-contact phase of the tackle event in rugby league match-play using video analysis and microtechnology. The research findings showed that ball-carriers had greater speed and acceleration than tacklers during the pre-contact phase, highlighting the significance for improving performance and player welfare.

Summary: This study focuses on Lagrangian modeling of heavy particle motion in inhomogeneous turbulence, proposing a model based on stochastic diffusion process to account for the effect of non-resolved flow scales on particle motion. The model considers turbulence anisotropy and utilizes statistical estimates of subgrid quantities for validation in turbulent channel flow cases, showing good results in LES computations.

Summary: Movienet is a novel deep learning approach that accelerates 4D-MRI reconstruction by exploiting space-time-coil correlations and motion preservation. It achieves subsecond reconstruction times and enables efficient acquisition of motion-resistant 3D anatomical imaging or motion-resolved 4D imaging. The results demonstrate that Movienet outperforms other methods in terms of reconstruction time and image quality.

Summary: This study investigates the effect of thickness and position of layers of saturated silt and sand on the site response of in situ ground. The response of the materials is modeled using a pressure dependent multi yield material model under undrained seismic loading. The results show that the introduction of a 0.5 m thick silt seam at different depths increases the hydraulic gradient, indicating the formation of a water film under sustained high pressure. Liquefaction and spectral accelerations are reduced, and there is no phase difference between the input acceleration record and the acceleration record at the ground surface.

Summary: Acceleration length and time are important in system design, but current equations lack simplicity and accuracy for designers. This study utilizes previous tests and a simple exponential model to describe particle velocity and acceleration, allowing for the calculation of acceleration length. The results show that the acceleration length can be effectively described by the Archimedes number, density ratio, and particle diameter. New tests were conducted to measure particle velocity as a function of time, confirming the newly-developed model that describes particle location, velocity, and acceleration over time. Based on this model, the acceleration time can be accurately calculated and is well described by the acceleration length and terminal velocity.
