Extraction of a target in sea clutter via signal decomposition Dear editor,Target detection at the sea surface is crucial for the ensuring the security of drilling platforms, ships,ports, etc. However, the presence of sea clutter poses a challenge to radar detection. Since the sea surface is ...
In this paper, a novel time-frequency signature using resonance-based sparse signal decomposition (RSSD), phase space reconstruction (PSR), time-frequency distribution (TFD) and manifold learning is proposed for feature extraction of ship-radiated noise, which is called resonance-based time-frequency...
Using our resonance-based nonlinear demodulation analysis method, we decompose the signal into high resonance, low resonance, and residual components. Then, we perform a demodulation analysis on the low resonance component that includes the fault information. We have verified the feasibility and ...
To address these issues, a novel compound fault features extraction technique based on parallel dual-parameter optimized resonance-based sparse signal decomposition (RSSD) and improved multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) is proposed in this contribution. Firstly, according to...
Keywords: ship-radiated noise; resonance-based sparse signal decomposition; manifold learning; phase space reconstruction; resonance-based time-frequency manifold 1. Introduction Underwater ship-radiated noise, in which entire spectra are widely distributed from as low as 5 Hz to as high as 100 KHz...
Silver posses narrower resonance curve thus providing a higher signal/noise ratio of SPR chemical sensors, but has a poor chemical stability. A new structure of resonant metallic film based on bimetallic silver/gold layers (gold as an outer layer) is suggested. It combines advantages of both ...
both Cu and Ce can catalyze the decomposition of H2O2to greatly increase the intratumoral level of lethal ROS. Subsequently, the free-radical level in cytoplasm is further evaluated. Here, DCFH-DA was applied to act as a fluorescence probe for verifying the in situ intracellular ROS generation....
The nanoplatform continuously catalyzed the decomposition of endogenous H2O2 to achieve oxygen self-sufficiency, while consuming GSH to reduce the loss of reactive oxygen species during radiotherapy, thus achieving an exciting combination of radiotherapy and CDT. Furthermore, Wang et al101 prepared block...
Bimetallic resonant films display so high shift of resonance angle on changes of ambient refraction index as gold films, but show narrower resonance curve, thus providing a higher signal / noise ratio. Additionally, the outer gold layer protects silver against oxidation. 展开 ...
