Fault diagnosis method of shearer planetary gear transmission systemunder variable speed conditions
Gong-kuang zidonghua, 2021 When the shearer cuts the coal seam, the planetary gear transmission system of the traction unit is in a variable speed working condition, and the structure of the planetary gear transmission system is complicated.

The record‐breaking heat wave of June 2019 in Central Europe
Atmospheric Science Letters, 2020 After being hit by several devastating heat waves in recent years, Europe experienced an exceptionally hot June in 2019 again. This June is the hottest one on record over Central Europe both in a monthly‐mean sense and in terms of the number of extremely

The Laplace resonance in the Kepler-60 planetary system [PDF]
, 2015 We investigate the dynamical stability of the Kepler-60 planetary system with three super-Earths. We first determine their orbital elements and masses by Transit Timing Variation (TTV) data spanning quarters Q1-Q16 of the KEPLER mission.

Contrast analysis between the trajectory of the planetary system and the periodicity of solar activity [PDF]
Annales Geophysicae, 2017 The relationship between the periodic movement of the planetary system and its influence on solar activity is currently a serious topic in research. The kinematic index of the planet juncture index has been developed to find the track and variation of

Stability and Formation of the Resonant System HD 73526 [PDF]
, 2007 Based on radial velocity measurements it has been found recently that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as our numerical integration shows, the derived orbital data for this system result in chaotic ...

Planetary systems in star clusters [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractIn the solar neighborhood, where the typical relaxation timescale is larger than the cosmic age, at least 10% to 15% of Sun-like stars have planetary systems with Jupiter-mass planets. In contrast, dense star clusters, characterized by frequent close encounters, have been found to host very few planets.
