Unidirectional ocular flutter [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 2006 Ocular flutter is a rare abnormal eye movement consisting of irregular bursts of to-and-fro bidirectional horizontal saccades and is frequently encountered in association with cerebellar symptoms. We present a patient with a probable post-infectious ocular flutter that exhibited characteristics not previously reported in the literature.

Electrophysiological Mechanisms of Atrial Flutter
Indian Pacing and Electrophysiology Journal, 2006 Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about

Flutter instability analysis of bridge decks using the step-by-step method
Vietnam Journal of Mechanics, 2014 The branch switch characteristics of coupled flutter are clarified by use of Step-by-Step flutter analysis. In the case of typically coupled flutter instability, the branch switch characteristic from torsional branch to heaving branch is observed.

Flutter of a Low-Aspect-Ratio Rectangular Wing [PDF]
A flutter test of a low-aspect-ratio rectangular wing was conducted in the Langley Transonic Dynamics Tunnel (TDT). The model used in this flutter test consisted of a rigid wing mounted to the wind-tunnel wall by a flexible, rectangular beam.

Minimum mass sizing of a large low-aspect ratio airframe for flutter-free performance [PDF]
A procedure for sizing an airframe for flutter-free performance is demonstrated on a large, flexible supersonic transport aircraft. The procedure is based on using a two level reduced basis or modal technique for reducing the computational cost of ...
