Structure and Bending Properties of Central Part of Tail Fin of Dolphin

Journal of Biomechanical Science and Engineering, 2010
Dolphins swim by vertical oscillation of their tail fins which have been considered to play an important role for generating thrust. The propulsive performance of the tail fin relates with the structure and the mechanical properties of the tail fin.

Survival Rates and Capture Heterogeneity of Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland

Frontiers in Marine Science, 2021
Adult survival is arguably the most important demographic parameter for long-lived species as it has a large impact on population growth, and it can be estimated for cetacean populations using natural markings and mark-recapture (MR) modelling.

A 32-mV Supply Ring Oscillator Composed of Modified Schmitt Trigger Delay Cells for Integrated Start-Up Circuits in DC Energy Harvesting Systems

IEEE Access
Implementing fully integrated start-up energy harvesting (EH) systems is very challenging. The most popular start-up circuit implementations use a low-voltage ring oscillator (RO).
