Abstract Variational mode decomposition (VMD) has been proved to be useful for extraction of fault-induced transients rolling bearings. Multi-bandwidth manifold (Triple M, TM) is one variation the VMD, which units multiple fault-related modes with different bandwidths by a nonlinear learning algorithm named local tangent space alignment (LTSA). The merit TM method that bearing extracted contain...

Quantum devices often suffer from reflections and noise during readout, a problem traditionally addressed by magneto-optical isolators circulators. However, these solutions are hindered limited bandwidth, low tunability, high losses, incompatibility with planar technologies like circuit QED. To overcome challenges, we introduce an approach to quantum non-reciprocity, leveraging the inherent non...

The multi pulse position amplitude modulation scheme for time-hopping multiple access impulse radio ultrawideband communication systems has been presented in this paper. Multi pulse position amplitude modulation is a hybrid modulation technique, which combines multi pulse position modulation and pulse amplitude modulation. It is shown that multi pulse position amplitude modulation significantly...
