Effects of urging by the rider on gallop stride characteristics of quarter horses
Journal of Equine Veterinary Science, 1988Summary The effects of urging by the rider on the limb contact patterns of the gallop stride were documented using high-speed cinematography. The subjects were 4 Quarter Horse fillies, approximately 30 months old, that were raised, housed, fed and trained alike.

2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019
Transmission line galloping is one of the most important disasters of power grid in winter. Based on the galloping observations and loss records obtained from the State Grid Corporation of China (SGCC), the distribution characteristics and the key meteorological factors of galloping events are analyzed. The results show that the galloping events appear

2018 12th International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2018
Conductor galloping is a common phenomenon during the operation of the transmission line, which can easily result in electrical accidents such as flashover and tripping caused by insulation breakdown of the inter-phase spacers. In this paper, a multi-span 4DOF (4 degree-of-freedom) dynamic model for the conductor-insulator is established, and the ...

AbstractBased on the simplified planar quadruped model with a passive spine joint, this paper focuses on studying the effect of the spine joint on the dynamic performance and the stability of the rotary galloping gait. The stable, periodic, and symmetric rotary galloping gait is achieved by the particle swarm optimization method without any parameter ...
