A novel dual-stator hybrid excited synchronous wind generator [PDF]
, 2009 This paper presents a novel dual-stator hybrid excited synchronous wind generator and describes its structural features and operation principle. The no-load magnetic fields with different field currents are computed by 3-D finite-element method.

A Molecular-Rotor Device for Nonvolatile High-Density Memory Applications [PDF]
, 2010 A novel memory device based on an electrically driven molecular rotor was fabricated and demonstrated to have bistable switching effects. The device showed an on/off ratio of approximately 10^4, a read window of about 2.5 V, and retention performance of

Arbitrary d–q current sharing in three-phase winding sets of multi-phase machines
The Journal of Engineering, 2019 This study proposes a technique for arbitrary current sharing between winding sets of any multiple three-phase machine by using a decoupled control in two-dimensional orthogonal vector space decomposition subspaces.
