SEMINAR: Low-Dimensional, Time Delay Models of Unsteady Aerodynamics and Feed-Forward Control

January 25, 2019 @ 10:00 am - 11:00 am
EB3 2207, 911 Oval Drive
Raleigh, NC 27695

Abstract: Different versions of time delay and decay models have been used to model unsteady aerodynamics and the effects of actuation on the lift of maneuvering airfoils. Recent measurements at Technion of the lift coefficient history obtained from a NACA 0018 airfoil undergoing pitching maneuvers with blowing-type active flow control were used to obtain low-dimensional models for control. Disturbance models for the lift response to pitching at different steady state blowing amplitudes were identified based on a variation of the…

SEMINAR: Ultrasound Elasticity Imaging and Therapeutics

April 12, 2019 @ 10:00 am - 11:00 am
EB3 2207, 911 Oval Drive
Raleigh, NC 27695

Abstract: Elasticity imaging techniques aim at the detection of tissue abnormalities following an external, internal or inherent mechanical stimulation. By taking advantage of the additional depth information provided by ultrasound imaging, the local tissue response (i.e., displacement, strain and/or vibration amplitude) that depends on its mechanical properties can be imaged. After introducing methods for 2D and 3D strain estimation, examples will be shown on imaging of normal and pathological myocardium in finite-element models and in vivo murine, canine and human…
