Characteristics of Wake-up Stroke
Journal of Stroke and Cerebrovascular Diseases, 2014Wake-up stroke (WUS) accounts for up to 29.6% of ischemic strokes, but its mechanisms are poorly understood. The purpose of this study is to identify risk factors and characteristics of WUS.Seven-two ischemic strokes were classified as WUS or non-WUS.

Aerodynamic characteristics of hypersonic wakes.
AIAA Journal, 1967A comprehensive experimental program has been conducted in the ballistics range facilities of the U. S. Naval Ordnance Laboratory to determine various aerodynamic characteristics of wakes behind hypervelocity bodies. The effects of Mach number, Reynolds number, and wall-to-stagnation enthalpy ratio on base flow geometry and transition from laminar to ...

Growth Characteristics of Turbulent Wakes
Canadian Journal of Physics, 1973Recent advances in the experimental study of hypersonic wakes at the Defence Research Establishment Valcartier have led to spatially resolved measurements of the behavior of the important physical variables which characterize the wake. Previous measurements pertained mainly to the wake growth, and they were achieved by an integrated-type technique ...

Far-field wake-vortex characteristics of wings
7th Fluid and PlasmaDynamics Conference, 1974Velocity measurements have been made in the wake of wings that were being towed underwater. As the wake aged, measurements of the tangential and axial velocity profiles were made with a two-dimensional scanning laser velocimeter at downstream distances of 5 to 200 span lengths behind wings with different span loadings.

Unsteady Turbine Blade Wake Characteristics
Volume 6: Turbo Expo 2003, Parts A and B, 2003The paper presents an experimental investigation of large coherent structures, commonly referred to as “von Karman vortex street”, in the wake of a turbine blade at high subsonic Mach number (M2,is = 0.79) and high Reynolds number (RE = 2.8×106 and their effect on the steady and unsteady pressure and temperature distribution in the wake.
