MHD Study of Extreme Space Weather Conditions for Exoplanets With Earth‐Like Magnetospheres: On Habitability Conditions and Radio‐Emission by J. Varela, A. S. Brun, P. Zarka, A. Strugarek, F. Pantellini, V. Réville

“…Exoplanets hosted by M stars at 0.2 au are protected from the stellar wind during regular and coronal mass ejection (CME)‐like space weather conditions if the star rotation period is slower than 3 days. Exoplanets hosted by a F stars at ≥2.5 au are protected during regular space weather conditions, but a stronger magnetic field compared to the Earth is mandatory if the exoplanet is close to the inner edge of the star habitable zone (2.5 au) during CMEs. …”

The Circulation Distribution on the Lifting Line for a Given Extracted Power by Ali Helali, Badreddine Kamoun, David Afungchui, Mohamed Jomaa Safi

“…In the second, the optimal circulation distribution is selected such that the kinetic energy of the wind downstream of the rotor disc is minimum, when the energy extracted by the wind turbine for one rotating period is imposed. A code has been developed which incorporates the real pitch of the helicoidal vortex wake. …”

Transmission Performance Analysis of Universal Coupling Spider by Wenjun Mao, Yinhua Zhang, Weihua Song, Changhai Tian, Guoliang Geng, Haiquan Li

“…Taking the universal coupling with spider of heavy-duty maintenance machinery as study object， the kinematics theory is used to analyze the performance of the universal coupling with spider when the input shaft rotates at a uniform speed， and the output shaft rotates periodically unevenly around the circumference. It quantitatively expressed the unevenness of the universal coupling with spider from the aspects of angular speed ratio， coefficient of unevenness and angular acceleration. …”
