The external rotor surface permanent magnet (SPM) machine is attractively used for in-wheel traction application. In view of energy consumption, the efficiency of SPM machine over a driving cycle is more important than that at a single working point. This paper focuses on optimizing the external rotor SPM machine considering a target driving cycle. Under a target driving cycle, the whole motor working...
The mobile cloud computing (MCC) that takes wireless access network as transmission medium and uses mobile devices as client becomes the newest evolution trends of cloud computing. When offloading the complicated multi-task application to the MCC environment, each task executes individually in terms of its own computation, storage and bandwidth requirement. Due to user's mobility, the provided resources...
Heterogeneous networks (HetNets) have been considered as a promising technique for improving spectral efficiency, but the energy efficiency influenced by the fluctuation of user numbers should not be neglected to achieve green communications. We introduce the energy-efficient switch-off mode algorithm for pico cells to reduce power consumption in the self-organizing network (SON). Once the switch-off...
