Intelligent diagnosis of gearbox in data heterogeneous environments based on federated supervised contrastive learning framework
Datasets
We assess the performance of the FSCL framework using two gearbox fault datasets: the Drivetrain Dynamic Simulator (DDS) dataset30, and our laboratory’s Wind Turbine Drivetrain Simulator (WTDS) dataset.
The DDS gearbox dataset includes a…

An experimental study on effect of curvatures of upstream tube on thermal performance of downstream tube in cross-flow of air
ST-ST tandem tubes
The tandem tube combination ST-ST refers that both are straight tubes based on longitudinal axis. Their centre-to-centre spacing ratio (SR = L/D = 2.0–4.0.) was varied to determine local circumferential Nu for…

Investigation of cadmium removal using tin oxide nanoflowers through process optimization, isotherms and kinetics
Characterization of tin oxide nanoflowers
Formation of tin oxide nanoflowers was confirmed by SEM, XRD, FTIR, particle size distribution and point of zero charge (pHPZC) analysis. Figure 2a shows the FTIR spectrum of tin oxide nanoflowers between…
