non-destructive testing & evaluation methods are developed to inspect and investigate materialsand structures. ultrasonic testing is an ndt method can be used for measuring the thickness ofobjects, as one of its significant applications. the objective of this paper is designing and applyingan intelligent ut fuzzy control system for evaluating the thickness of thin metal objects in a rangeof...

corrosion of reinforcing steel and other embedded metals is the main cause of severe deterioration in reinforced concrete structures which subsequently imposes adverse effects on ultimate and serviceability limit state performance of the whole structure. in this paper, a new corrosion detection method for reinforced concrete beams, based on wavelet analysis is presented. to evaluate the capabil...

quality evaluation is one of the effective activities in trade, economy and the health of communities. for this purpose, non-destructive methods are increasingly used, as they are faster and more economical in comparison with destructive ones. this study investigated the feasibility of predicting firmness by laser light backscattering imaging system, as a new non-destructive method for one cult...
