Sensitivity Analysis of Geometrical Parameters on the Aerodynamic Performance of Closed-Box Girder Bridges

Sensors, 2018
In this study, the influence of two critical geometrical parameters (i.e., angles of wind fairing, α; and lower inclined web, β) in the aerodynamic performance of closed-box girder bridges was systematically investigated through conducting a ...

Calculation of AGARD Wing 445.6 Flutter Using Navier-Stokes Aerodynamics [PDF]

, 1993
An unsteady, 3D, implicit upwind Euler/Navier-Stokes algorithm is here used to compute the flutter characteristics of Wing 445.6, the AGARD standard aeroelastic configuration for dynamic response, with a view to the discrepancy between Euler ...

Comparison of clinical outcomes and safety of catheter ablation for atrial fibrillation supported by data from CT scan or three-dimensional rotational angiogram of left atrium and pulmonary veins

Biomedical Papers, 2015
Background: Catheter ablation in the left atrium has become a common therapeutic strategy in the management of atrial fibrillation (AF). The high degree of success and safety profile of this procedure is dependent on precise knowledge of the true anatomy

MULTI-MODE FLUTTER ANALYSIS AND TWO & THREE DIMENSIONAL MODEL TESTS ON BRIDGES WITH NON-ANALOGOUS MODAL SHAPES

Doboku Gakkai Ronbunshu, 1993
Coupled flutter of non-analogous vertical and torsional modes, which may typically occur in mono-cable suspension or single plane cable-stayed bridges, for example, and multimode flutter including higher modes are studied both analytically and experimentally.
