We introduce a Quantum Electrodynamics (QED) approach to describe inelastic scattering processes of molecules in atomic-scale plasmonic picocavities. By solving the corresponding optomechanical dynamics, we identify nonlinear inelastic signals related to vibrational pumping, together with dynamical backaction and strong correlations of the photons emitted.
The Acoustic Vector Sensor can measure both pressure and particle velocity information of acoustic field at a point in space. By using the acoustic pressure and particle velocity information, a single AVS can get the unbiased estimation of target's bearing. But when the phase of each channel is inconsistent, the estimation precision will be badly affected. In order to solve this problem, this paper...
Mining activities has caused long-term change in land surface and hydrological cycle. Accurate information of vegetation structure is important for assessing how mining activities affect ecosystem in mining areas. A remote sensing method based on vegetation cover monitoring and assessment by using Landsat data sets with the temporal coverage from 1989 to 2015 was presented and applied to the Pingshuo...
Discriminative feature extraction (DFE) is an effective linear dimensionality reduction method for pattern recognition. It improves the recognition performance via optimizing subspace projection axes and classifier parameters simultaneously. In this paper, we propose a nonlinear extension of DFE, called discriminative quadratic feature extraction (DQFE), for which feature vectors are firstly mapped...
Partial discharges (PD) in HVDC equipment are not the predominant degradation factor. However, they can be a failure precursor (particularly when electrical trees are formed), so that monitoring PD could be a tool to infer imminent failures. In order to monitor PD on site, one major problem at DC voltage is the absence of tools able to distinguish noise from PD signals. In this paper, corona, surface...
