The perforated caisson structure is used in ports and waterways for its wave dissipation performance. This study modifies the traditional SPH method using Riemann solution CSPH to examine interaction between waves caissons. A comparative analysis of single- double-chambered caissons was conducted, considering various conditions. Results show that best occurs when perforation ratio front plate higher than back plate, chamber narrower chamber. Equal widths are beneficial adapting diverse...
The degradation of marine water pumps on ships is difficult to detect, and most the data from ship monitoring are unmarked highly unbalanced. Autoencoders have powerful analysis capabilities can better extract information data. Based Stacked (SAE) Support Vector Data Description (SVDD), a detection method for seawater proposed. Firstly, normal selected dataset using clustering algorithms. Secondly, used train SAE, ensuring that SAE only learns features samples. Finally, hidden layer...
A convolutional neural network (CNN) architecture is developed to improve the pulse shape discrimination (PSD) power of gadolinium-loaded organic liquid scintillation detector reduce fast neutron background in inverse beta decay candidate events NEOS-II data. spectrum an event constructed using a Fourier transform time domain raw waveforms and put into CNN. An early data set evaluated by CNN after it trained low energy $β$ $α$ events. The signal-to-background ratio averaged over 1-10 MeV...
