A solar cell defect detection method with an improved YOLO v5 algorithm is proposed for the characteristics of complex image background, variable morphology, and large-scale differences. First, deformable convolution incorporated into CSP module to achieve adaptive learning scale perceptual field size; then, feature extraction capability model enhanced by introducing ECA-Net attention mechanism...

Defect detection on the surface of steel strip is essential for quality assurance strip. Precise localization and classification, two significant tasks defect detection, still need to be completed due diversity scales. In this paper, a residual atrous spatial pyramid pooling (RASPP) module first designed enrich multi-scale information feature maps increase receptive field maps. Secondly, double...

introduction: machine vision, which uses image processing techniques, is a branch of artificial intelligence that simulates human vision. these systems can be used for quality control, sorting and grading of agricultural products. unlike engineering materials, agricultural fruits are living tissues that continue living even after they are harvested from trees or bushes. therefore, the post-harv...

We provide a brief overview on our recent experimental work on linear and nonlinear localization of singly charged vortices (SCVs) and doubly charged vortices (DCVs) in two-dimensional optically induced photonic lattices. In the nonlinear case, vortex propagation at the lattice surface as well as inside the uniform square-shaped photonic lattices is considered. It is shown that, apart from the ...

OBJECTIVE Neurologic complications during carotid artery stenting (CAS) are usually associated with distal embolic event. These embolic incident during CAS are highly associated with the carotid plaque instability. The current study was undertaken to identify the angiographic characteristics of carotid plaque vulnerability, which was represented as filling defect in the cerebral protection filt...

Paroxysmal nocturnal hemoglobinuria (PNH) is clinically characterized by intravascular hemolysis, hemoglobinuria, iron deficiency anemia, and venous thrombosis. Pathophysiologically the disease has now been generally accepted as an acquired defect of phosphatidylinositol glycan (PIG)-anchored molecules on the cell surface of bone marrow-derived cells. This defect is functionally characterized b...

invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. this report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper rig...
