Investigation of Non-Sinusoidal Oscillator Driven by Double Servomotors for Continuous Casting Mold

open access: yesIEEE Access, 2020
To improve the surface quality and casting speed of the slab further, a new type mold oscillator synchronously driven by double servomotors was proposed in this paper. The experimental prototype was designed and manufactured.

Non-Sinusoidal Bending Waves of Sperm Flagella* [PDF]

open access: yesJournal of Experimental Biology, 1965
ABSTRACT Photomicrographs giving greater resolution than previously available have been obtained for the spermatozoa of a sea urchin, a tunicate, and an annelid. The bending waves are not sine waves. They contain circular arcs, in which the amount of bending is constant, separated by shorter regions which are nearly straight.
