Calibration procedures for eddy current inspections often involve the use of artifact standards containing manufactured flaws. The manufactured flaw is assumed to be a good approximation of the type of flaw being sought during the inspection. These manufactured flaws are most often produced by electrical dis charge machining (EDM) , milling, or the controlled growth of fatigue cracks. With simp...

In order to corroborate the efficiency of PET bottle inspection equipment coupled with mass spectrometry detection, a method for determination of BTEX presented in the interior of returnable PET bottles was developed and validated. It was verified that the method was able to detect BTEX compounds in the range 0.1-10mL of gasoline.

EXECUTIVE SUMMARY The requirement for advanced security equipment to scan data streams for malicious content at line rate presents significant challenges to network security vendors. Security equipment, overwhelmed by the data rates of present-day networks, is more likely to miss attacks, leading to increased risks of security breaches. While highspeed content scanning, also known as deep packe...

The special characteristics providing protection to explosion for equipment design use in potentially explosive atmospheres must be preserved during their entire period of use. Thus, the designed atmosphere shall subjected specific inspections order verify that on which is based were not depreciated time. purpose paper underline importance case intended used and provide recommendations this mat...

A selective acoustic activation of defects based on the concept of Local Defect Resonance (LDR) enables to enhance considerably the intensity of defect vibrations and makes it possible to reduce the input acoustic powers to the levels permissible for noncontact nondestructive inspection. Since for cm-size defects in composite materials, the LDR frequencies lie in the low kHz-range the resonant ...
