Improved In-Line VIV Prediction for Combined In-Line and Cross-Flow VIV Responses [PDF]

Volume 2: Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV, 2017
Slender marine structures are subjected to ocean currents, which can cause vortex-induced vibrations (VIV). Accumulated damage due to VIV can shorten the fatigue life of marine structures, so it needs to be considered in the design and operation phase.

Redo Surgical Mitral Valve Replacement Versus Transcatheter Mitral Valve in Valve From the National Inpatient Sample

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Redo mitral valve surgery is required in up to one‐third of patients and is associated with significant mortality and morbidity. Valve‐in‐valve transcatheter mitral valve replacement (ViV TMVR) is less invasive and could be considered in those

Reliability Based Factors of Safety for VIV Fatigue Using NDP Riser High Mode VIV Tests [PDF]

, 2011
Understanding the level of conservatism in a riser system design for vortex-induced vibration (VIV) fatigue is an important issue for operators. This study represents a demonstration of the calibration methodology to derive consistent values for the ...

Predictors of Procedural Success in Patients With Degenerated Surgical Valves Undergoing Transcatheter Aortic Valve-in-Valve Implantation

Frontiers in Cardiovascular Medicine, 2021
Background: Valve-in-Valve transcatheter aortic valve implantation (ViV-TAVI) is a growing alternative for redo-surgery in patients with degenerated surgical valves. To our knowledge, data are lacking on the determinants on ViV-TAVI procedural success in

A Study on the Vortex Induced Vibration of a Cylindrical Structure with Surface Bulges

Journal of Marine Science and Engineering, 2022
Inspired by the cactus in nature, a cactus-like cross-sectional structure was proposed to achieve the VIV suppression. The VIV of the elastically mounted cylinder was realized based on the ANSYS Fluent and User Defined Function (UDF).

Automatic Identification of Bridge Vortex-Induced Vibration Using Random Decrement Method

Applied Sciences, 2019
Vortex-induced vibration (VIV) has been occasionally observed on a few long-span steel box-girder suspension bridges. The underlying mechanism of VIV is very complicated and reliable theoretical methods for prediction of VIV have not been established yet.

HOW ADVERTISING SHAPES OUR MINDS: PRAGMATIC AND COGNITIVE PERSPECTIVE [PDF]

Journal of Languages for Specific Purposes, 2016
The immense role of advertising in modern world can hardly be limited only to persuading the addressee to buy a certain product. Its functions extend far beyond informing, influencing or stimulating and reach the level of cognition and conceptualization.
