Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

open access: yesAdvanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Resonant technique for bidirectional flyback converter

open access: yesElectronics Letters, 2009
Proposed is an improvement of the bidirectional flyback topology, proposing a resonant inversion of the output polarity voltage. The topology is applied to supply high pressure sodium lamps with a low frequency symmetrical square waveform, in order to avoid the acoustic resonance phenomenon occurrence.
