This letter presents a point cloud based robotic system for arc welding. Using hand gesture controls, the scans partial views of workpiece and reconstructs them into complete 3D model by linear iterative closest algorithm. Then, bilateral filter is extended to denoise preserve important geometrical information. To extract welding seam from model, novel intensity-based algorithm proposed that de...

A simple and fast Cloud Point Extraction (CPE) preconcentration of Acid Blue 29 (AB 29) dye was developed prior to its spectrophotometric determination. The suggested procedure successfully applied for the determination AB in different water samples with high recoveries. Optimization experimental conditions such as surfactant type volume, pH, stirring, centrifugation were studied. effect interf...
