Experimental study of cactus-like body shape on flow-induced vibration mitigation of clustered cylinders

International Journal of Naval Architecture and Ocean Engineering, 2021
Vortex-Induced Vibration (VIV) is a major contributor to the fatigue damage of marine risers which are often arranged in an array configuration. In addition to helical strakes and fairings, studies have been strived in searching for possible VIV ...

Experimental study on the influence of maintenance track position on vortex-induced vibration performance of a box girder suspension bridge

Frontiers in Built Environment, 2023
To study the influence of maintenance track on the vortex-induced vibration (VIV) performance of main girder, the VIV response and time history of surface pressure data of a section model were obtained by wind tunnel vibration and pressure measurements ...

Study on the effect of corrosion defects on VIV behavior of marine pipe using a new defective pipe element

International Journal of Naval Architecture and Ocean Engineering, 2020
After long-term service in deep ocean, pipelines are usually suffered from corrosions, which may greatly influence the Vortex-Induced Vibration (VIV) behavior of pipes. Thus, we investigate the VIV of defective pipelines.

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±
