THE INFLUENCE OF QUANTUM VACUUM FRICTION ON PULSARS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We first revisit the energy loss mechanism known as quantum vacuum friction (QVF), clarifying some of its subtleties. Then we investigate the observables that could easily differentiate QVF from the classical magnetic dipole radiation for pulsars with accurately measured braking indices (n). We show that this is particularly the

Grease composition influence on friction & starvation
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021 Nowadays, grease lubrication is frequently used in rolling element applications such as bearings or constant velocity joints. The advantage of grease is to supply lubrication to the application without leaking thanks to its consistency. Nevertheless, starvation can occur leading to damage such as scuffing.

High-Fidelity Fin–Actuator System Modeling and Aeroelastic Analysis Considering Friction Effect
Applied Sciences, 2021 Both the dynamic characteristics and structural nonlinearities of an actuator will affect the flutter boundary of a fin–actuator system. The actuator models used in past research are not universal, the accuracy is difficult to guarantee, and the ...

The Interface Friction in The Friction-Type Bolted Joint of Steel Truss Bridge: Case Study
The Baltic Journal of Road and Bridge Engineering, 2020 The friction-type bolted joint transfers the internal forces in the structural members by interface friction, but noticeable seasonal temperature and bolt fracture cause the redistribution of interface friction and threaten the joint safety.

Influence of Flood on the Behavior of Friction Piles
, 2020 Structures are commonly supported on pile foundations at locations having marginal soil. Friction piles are provided wherever the depth to a hard stratum is large. The load settlement behavior of a friction pile entirely depends on the interaction between soil and the pile material at their interface.
