Wave reflection at a free interface in an anisotropic pyroelectric medium with nonclassical thermoelasticity [PDF]
, 2016 In this paper, the well-established two-dimensional mathematical model for linear pyroelectric materials is employed to investigate the reflection of waves at the boundary between a vacuum and an elastic, transversely isotropic, pyroelectric material.

Aerodynamic characteristics and excitation mechanisms of the galloping of an elliptical cylinder in the critical Reynolds number range [PDF]
Journal of Wind Engineering and Industrial Aerodynamics, 2017 Abstract The generation mechanisms of dry cable instabilities in the critical Reynolds number range are still unclear because of their complicated aerodynamic forces and a shortage of studies on the coupling process. Large amplitude vibrations of an elliptical cylinder in the critical Reynolds number range are reproduced in a wind tunnel, and ...

Enhanced mechanical energy extraction from transverse galloping using a dual mass system [PDF]
, 2014 This paper offers a theoretical study of energy extraction through transverse galloping using a dual-mass system. To this end, a two-degree-of-freedom model is developed where fluid forces on the galloping body are described resorting to quasi-steady ...

Energies, 2021 According to the engineering phenomenon of the galloping of ice-coated transmission lines at certain wind speeds, this paper proposes a novel type of energy harvester based on the galloping of a flexible structure. It uses the tension generated by the galloping structure to cause periodic strain on the piezoelectric cantilever beam, which is highly ...

Chaotic Vibrations in a Buckled Beam Induced by a Galloping Phenomenon [PDF]
, 2008 Chaos theory has spectacularly evolved since the pioneering work by E. Lorenz on chaotic motion in a simple, deterministic system. Since then, the chaotic behavior of many other deterministic, low-dimensional systems in a large variety of fields has been ...

Energy cost and return for hunting in African wild dogs and Cheetahs [PDF]
, 2016 African wild dogs (Lycaon pictus) are reported to hunt with energetically costly long chase distances. We used high-resolution GPS and inertial technology to record 1,119 high-speed chases of all members of a pack of six adult African wild dogs in ...

An ultra low-power galloping monitoring sensor based on acceleration measuring unit
Journal of Physics: Conference SeriesThe galloping of transmission lines is a phenomenon that transmission lines vibrate and wobble due to the influence of weather, power load, wire distortion and other factors in the process of power transmission.
