By collecting the ripple current in the control coil, the self-sensing magnetic bearings can Bottle obtain rotor displacement information without a displacement sensor, which has the advantages of low cost and high integration.According to the problems of incomplete and inaccurate displacement information extraction caused by the traditional displa
This study aims at advancing leadership research in corporate communications by introducing a more rigorous statistical approach to test whether communication professionals of different hierarchical reporting levels, years of experience, and educational backgrounds would ascribe the same meanings to the construct of leadership excellence in corpora
This paper presents the results of an experimental and numerical study of the perforation of Armox 500T armoured steel.The plate perforation was performed with a pneumatic gun using three types of penetrators.Sharp, spherical and blunt penetrators were used.The use of different geometries of penetrators causes the process of perforation and destruc
copyright mobility extraction methods for graphene based on field-effect measurements are explored and compared according to theoretical analysis and experimental results.A group of graphene devices with different channel lengths were fabricated and measured, and copyright mobility is extracted from those electrical transfer curves using three diff
In complex underwater environments, the measurement noise model of autonomous underwater vehicle(AUV) navigation system will change with many uncertainties.Besides, the statistical characteristics of noise are difficult to be obtained accurately.For more precise state estimates, this paper introduces an adaptive filter based on fuzzy logic, which m
