The Double Permanent Magnet Vernier (DPMV) machine is well known for its high torque density and magnet utilization ratio.This paper aims to investigate the torque generation mechanism and its improved design in DPMV machines for hub propulsion based on the field modulation principle.Firstly, the topology of the proposed DPMV Chafers machine is int
BACKGROUND:The precision of the metaphase-anaphase transition ensures stable genetic inheritance.The spindle checkpoint blocks anaphase onset until the last chromosome biorients at metaphase plate, then the bonds between sister chromatids are removed and disjoined chromatids segregate to the spindle poles.But, how sister separation is triggered is
An optimal thruster configuration for attitude control subsystem of a spacecraft is presented in this paper.The optimal configuration is designed according to minimum number of required thrusters for satisfying desired reliability with specific redundancy level.The genetic algorithm is employed for optimization process and feasibility of the result
Although chaotic systems with self-excited and hidden attractors have been discovered recently, there are few investigations about relationships among them.In this paper, using a systematic exhaustive computer search, three Autographed Football Jerseys elementary three-dimensional (3D) dissipative chaotic jerk flows are proposed with the unique fea
This study is focused on the development of a Bayesian network for air quality assessment and aims at offering a pragmatic and scientifically credible approach to modelling complex systems where substantial uncertainties exist.In particular, the main object is Autographed Football Jerseys the prediction of the occurrence of suitable conditions for
