New insights into the evolution of the surface antennal sensory equipment in free-living and cave-dwelling beetles (Leiodidae: Leptodirini)

The stable environment of subterranean realms is characterized by constant darkness, temperature and humidity, and scarcity of resources.This led to similar adaptations in different lineages of animals, such as Castor Oil the reduction of eyes and pigmentation.It is common textbook knowledge that blindness in cave insects is compensated for by tran

Vibration energy harvesting for low frequency using auto-tuning parametric rolling pendulum under exogenous multi-frequency excitations

ABSTRACT: An electromagnetic parametrically excited rolling pendulum energy harvester with self-tuning mechanisms subject 5/8" to multi-frequency excitation is proposed and investigated in this paper.The system consists of two uncoupled rolling pendulum.The resonance frequency of each the rolling pendulum can be automatically tuned by adjusting its
