Webdamping induced by the blockage of antegrade perfusion. If the vessel is small in diameter and the catheter is larger than the vessel ostium, a side-hole catheter should be preferred [2]. Using a side-hole large catheter not only decreases damping, but also lowers the risk for vessel dissection that may be induced by contrast agent injection.

WebMar 22, 2024 · De-branching small (Spatz et al. 2007) or large (Milne 1991) conifers with a single pruning increased frequency and decreased damping ratio, but repeated partial pruning of large conifers (Moore and Maguire 2005) or a single, large decurrent tree (James 2014) revealed that the effect on frequency was negligible until more than 80% of crown … WebIn this work, the nonlinear behaviour of a parametrically excited system with electromagnetic excitation is accurately modelled, predicted and experimentally investigated. The equations of motion include both the electromechanical coupling factor and the electromechanical damping. Unlike previous studies where only linear time-varying stiffness due to …
WebDamping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. [1] Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down ...
