Aiming at overcoming the shortage of high cogging torque in flux-switching permanent magnet machine (FSPM), a novel coaxial double flux-switching permanent magnet machine was proposed. The electromagnetic characteristics of the machine, including flux linkage, back EMF, cogging torque, static torque, are studied by means of finite element method in this paper. The study results of this paper show...
Switched reluctance machine (SRM) and flux-switching machine (FSM) with segmental rotors are different in winding patterns and control strategies. The electromagnetic characteristics of the two machines, including magnetic field, static torque, torque ripple, iron loss and efficiency, are compared by means of analytical calculation and finite element method in this paper. The analytical results of...
Recently, the computational requirements for large scale data-intensive analysis of scientific data have grown significantly. In High Energy Physics (HEP) for example, the Large Hadron Collider (LHC) produced 13 petabytes of data in 2010. This huge amount of data are processed on more than 140 computing centers distributed across 34 countries. The MapReduce paradigm has emerged as a highly successful...
