Research and exploration on cymatics in sound visualization by Yun Gao, Jiali Xia

“…Sand, as it travels from the area of the vibrating sections of the plate to places where the vibration does not reach, creates interesting forms of a symmetrical nature (lines, ovals, waveforms, ellipses and even straight edges). Those areas of the plate in which the vibration does not fall are called nodal points and lines.…”

Shape-shifting polyhedral droplets by Pierre A. Haas, Diana Cholakova, Nikolai Denkov, Raymond E. Goldstein, Stoyan K. Smoukov

“…Cooled oil emulsion droplets in aqueous surfactant solution have been observed to flatten into a remarkable host of polygonal shapes with straight edges and sharp corners, but different driving mechanisms—(i) a partial phase transition of the liquid bulk oil into a plastic rotator phase near the droplet interface and (ii) buckling of the interfacially frozen surfactant monolayer enabled by a drastic lowering of surface tension—have been proposed. …”

Fabrication of Nanogroove Arrays on Acrylic Film Using Micro-Embossing Technique by Chana Raksiri, Potejana Potejanasak, Thitipoom Dokyor

“…On the other hand, the effect of increasing the embossing temperature on the morphology of nanogrooves agrees with the master mold, and the crests between the nanogrooves form straight edges. It should be noted that the micro-embossing temperature also strongly influences the transferability of nanopatterns on an acrylic film. …”

AUTOMATED BLUR DETECTION AND REMOVAL IN AIRBORNE IMAGING SYSTEMS USING IMU DATA by C. A. Shah, W. Schickler

“…Their limitations are – (1) MTF calculation requires presence of straight edges in the image scene, which may not always be available, (2) Due to the absence of an ideal edge, the amount of blur estimated is relative, and (3) It is computationally expensive and therefore may not be practical for blur detection in real time applications. …”
