The Industrial Internet of Things (IIoT) offers the manufacturing sector opportunities for transformation and upgrade but also carries significant security risks. Traditional federated learning (FL) as a potential solution is challenging in complicated application environments with heterogeneous data, imbalanced poisoning attacks. To address these challenges, we construct clustered FL Framework IIoT intrusion detection (CFL-IDS) based on local models' evaluation metrics (EMs). First,...
Due to the merits of Lamb wave Structural Health Monitoring (SHM) composite, wave-based damage detection and identification technology show a potential solution for insulation condition evaluation large generator stator. This was performed in order overcome problem that it is difficult effectively identify stator using single feature wave. In this paper, method based on multi-feature fusion presented. Firstly, different features were extracted from time domain, frequency fractal dimension...
If the neutral point either on primary or secondary side of potential transformer is not grounded directly, harmonic voltage measurement will reflect real distortion system voltage.

Effective insulation condition diagnosis for large generator stator is critical to ensure safe operation and extend life. In this study, elastic guided waves probability imaging approach introduced detect damage. A distributed actuator-sensor network was established acquire Lamb wave signals before after the presence of Flight time scattered were calculated using Hilbert transform locate Gaussian distribution employed quantify damage at different spatial locations in bar. The features...
With the rapid development of Internet Things (IoT) technology, Network Function Virtualization (NFV) is introduced in edge network to provide flexible and personalized service. However, there still exist some problems be solved, such as high cost, unbalanced load, low availability. Therefore, a reliability-and-energy-balanced Service Chain (SFC) mapping migration method presented for IoT applications. First, aiming at improving performance reducing expenditure, an SFC algorithm based on...
Personal cloud storage is rapidly gaining popularity. A number of Internet service providers, such as Google and Baidu, entered this emerging market developed a variety services. These ubiquitous services allow people to access personal files all over the world at anytime. With prevalence mobile rich media on web, more use for storing working documents, music, private photos movies. Nevertheless, size often beyond upper limit that normal form-based file upload allows hence dedicated...
Abstract Co‐firing biomass in an existing coal combustion boiler is a promising way to mitigate carbon emission the context of global neutrality. This paper investigated effect injection location on and NO X formation characteristics 300‐MWe tangential co‐firing with coal. Numerical models have been validated against experimental measurement for both pure firing biomass/coal cases. Compared firing, case injected into highest layer can sustain comparable temperature distribution profile along...
