A review of recent literature on thrust generation mechanisms by a hydrofoil, bioinspired from fish locomotion is presented. The present work considers fish-inspired periodic kinematics of three types: pitching, heaving, and undulations along with the combination of some of these motions. The pitching...
Because of our sinful nature and our perpetual continuing to do so, John strongly declares “If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness” (1 John 1:9). As we confess, we are saying the same thing about our situ...

where λ is the wavelength of the sinusoidal profile, and i and j are the unit vectors in the x and y directions, respectively. The authors paid significant attention to the mathematical model of the motion of a flexible magnetic swimmer in an external magnetic field. It was shown that, in...
