Minimum mass sizing of a large low-aspect ratio airframe for flutter-free performance [PDF]

open access: yes
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 ...

Long-term results of catheter radiofrequency ablation of cavotricuspid isthmus in patients with typical atrial flutter and diabetes mellitus type 2

open access: yesRUDN Journal of Medicine, 2016
Aim - to evaluate the effectiveness of radiofrequency ablation cavotricuspid of the isthmus in patients with diabetes mellitus (DM) type 2, and typical atrial flutter, as well as to identify the factors of recurrence of atrial flutter after the procedure.

Transonic flutter study of a wind-tunnel model of an arrow-wing supersonic transport [PDF]

open access: yes
A 1/20-size, low-speed flutter model of the SCAT-15F complete airplane was tested on cables to simulate a near free-flying condition. Only the model wing and fuselage were flexible.
