Experimental investigation on the dynamic characteristics and transverse vibration instabilities of transmission belts [PDF]

, 2008
Serpentine belt drives are often used in front end accessory drive of automotive engine. Dynamic characteristics of belts play an important role in the behavior of such transmission and are inputs of simulation software. Moreover, free belt spans exhibit

A telescopic and microscopic examination of acceleration in the June 2015 geomagnetic storm: Magnetospheric Multiscale and Van Allen Probes study of substorm particle injection

Geophysical Research Letters, 2016
An active storm period in June 2015 showed that particle injection events seen sequentially by the four (Magnetospheric Multiscale) MMS spacecraft subsequently fed the enhancement of the outer radiation belt observed by Van Allen Probes mission sensors ...

Explaining the dynamics of the sub-relativistic electron third belt in the Earth’s radiation belts by using medium Earth orbit satellite observations

Earth and Planetary Physics
The Earth’s electron radiation belts typically exhibit a two-belt structure. However, observations from the Van Allen Probes revealed the existence of a three-belt structure.

Characteristic times for radiation belt drift phase mixing

Frontiers in Astronomy and Space Sciences
Impulsive radial transport events occurring in the radiation belts leave lasting marks in the form of drift echoes, that is, energy-dependent drift phase structures in the radiation belts that evolve at the drift frequency.
