SEMINAR: Plenoptic Cameras and Experimental Flow Diagnostics

March 22 @ 10:00 am - 11:00 am
EB3 2207, 911 Oval Drive
Raleigh, NC 27695

Abstract: Simplifying complex measurements: Plenoptic cameras and the future of experimental flow diagnostics Turbulence is inherently an unsteady and 3-D phenomena, yet classical fluid dynamic measurement techniques are typically limited to 1-D and 2-D measurements. Recent advances in multi-camera 3D flow measurements, such as tomo-PIV, hold tremendous potential to explore new problems and ideas; however, these techniques tend to be complex, expensive or inflexible. This seminar will focus on an emerging technology, the plenoptic (or light-field) camera that has the…

SEMINAR: Acoustic Metasurfaces

March 29 @ 10:00 am - 11:00 am
EB3 2207, 911 Oval Drive
Raleigh, NC 27695

Abstract: Wave manipulation using artificial materials is a central topic in materials physics. Recent years have witnessed the emergence of a family of thin, 2D artificial materials, namely, metasurfaces. The concept of metasurfaces was introduced to the materials and physics communities for optical waves in 2011 with the generalized Snell's law, which opened up a new degree of freedom for optical wave manipulation. Inspired by this pioneering work, and because acoustic waves also follow the Snell's law, a flurry of…

SEMINAR: A “Monologue” on the Mechanics of the Vagina

April 5 @ 10:00 am - 11:00 am
EB3 2207, 911 Oval Drive
Raleigh, NC 27695

Abstract: Pelvic floor disorders such as urinary incontinence, fecal incontinence, and pelvic organ prolapse represent a major public health concern in the United States affecting one third of adult women. These disorders are determined by structural and mechanical alterations of the pelvic organs, their supporting muscles and connective tissues that occur mainly during pregnancy, vaginal delivery, and aging. In this talk, I will present the research that is currently being conducted in my lab to characterize the nonlinear mechanical properties…

SEMINAR: Ultrasound Elasticity Imaging and Therapeutics

April 12 @ 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…
