Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role the dynamic variation of extent intensity belt. It is possible to model effects across long length time scales using quasi-linear theory, leading a Fokker-Planck equation describe waves on high energy electrons. This powerful theory renders efficacy interactio...

in this study, first energy absorption of axial and bending loading is considered. next, thin walled structures under oblique loading are investigated using abaqus computer simulation, where 180 different cases are simulated. simulation results of the thin walled structures under oblique loading were compared with the experimental results of nagel, and good agreement was perceived. simulation r...

The pitch control system has a profound impact on the development of wind energy, and yet delay or non-minimum phase can weaken its performance. Thus, there is strong incentive to enhance technology in order counteract negative effects unidentified delays characteristics. To reduce complexity parameter-tuning process improve performance system, this paper, we propose novel method for turbine an...

This paper introduces a method of design and implementation of a two-wheeled inverted pendulum (TWIP) robot with friction compensation. Friction in the drive mechanism is a critical factor of robot self-balancing and affects its performance. The friction parameters are identified based on the dynamic model of the drive mechanism. The dynamics of the whole robot system are obtained by the Lagran...
