چکیده
Many concrete structures in use have safety problems due to material deterioration, actual construction defects, structural damage, etc. Therefore, nondestructive testing is required determine the presence of defects. Ultrasonic technology an important tool testing, which can detect defects and be combined with other methods or models make it more accurate. At present, ultrasonic inspection has been research at home abroad, both theory engineering, there great progress. This paper summarizes latest progress for abroad respectively, points out future development trend.

Latest Research and Development on Software Testing Techniques and Tools
Software Testing is a process of finding errors while executing a program so that we get a zero defect software. It is aimed at evaluating the capability or usability of a program. Software testing is an important means of accessing quality of software. Though a lot of advancements have been done in formal methods and verification techniques, still we need software to be fully tested before it ...

متن کاملResearch on Embedded Sensors for Concrete Health Monitoring Based on Ultrasonic Testing
In this article, embedded ultrasonic sensors were prepared using 1–3-type piezoelectric composite and piezoelectric ceramic as the piezoelectric elements, respectively. The frequency bandwidth of the novel embedded ultrasonic sensors was investigated. To obtain the relationship between the receiving ultrasonic velocity and compressive strength, as well as their response signals to crack damage,...
متن کاملPulse compression technique applied to ultrasonic nondestructive testing of concrete
The pulse compression technique is successfully and widely used in many fields for improving the signal to noise ratio (SNR); which is especially useful when the environment is noisy and the SNR is poor. Since high frequency ultrasound is strongly attenuated in concrete, only low frequency ultrasound can be used in ultrasonic nondestructive testing (NDT) of concrete. In this study the pulse com...
متن کاملSome Progress in Software Testing Technology
Estimating total software defects using capture-recapture models Used by software engineers since the 1970s to estimate the number of defects in software code, the capture-recapture method was first proposed by Laplace in 1786 for biological populations. The model can be described by the following scenario. Suppose a ranger wishes to estimate the number of wolves in his park. He captures, tags,...
