By using the crack line analysis method, this paper carries out an elastic-plastic analysis for mode I cracks under plane stress condition in an elastic perfectly plastic solid and obtains the general form of matching equations of the elastic stress field and the plastic stress field near the crack line in rectangular coordinate form.The analysis i
Accurate detection of ripple components of the direct-current (DC) signals is essential for evaluating DC power quality.In this study, the combination algorithm based on variational mode decomposition (VMD) and Hilbert transform (HT) is applied to detect and analyze the characteristics of the ripple components of the DC disturbance signals.Firstly,
This Proposed work explores how machine learning can be used to diagnose conjunctivitis, a common eye ailment.The main goal of the study is to capture eye images using camera-based systems, perform image pre-processing, and employ image segmentation techniques, particularly the UNet++ and U-net models.Additionally, the study involves extracting fea
