The detection, isolation, and characterization of flaws in components represent a critical need in manufacturing and quality control. Nondestructive testing (NDT) provides an effective way of inspecting materials for ensuring the quality and integrity of products and systems. Consequently, nondestructive inspection finds extensive application in several industries such as steel, nuclear and ele...

Electromagnetic nondestructive tests are important and widely used within the field of nondestructive evaluation (NDE). The recent advances in sensing technology, hardware and software development dedicated to imaging and image processing, and material sciences have greatly expanded the application fields, sophisticated the systems design and made the potential of electromagnetic NDE imaging se...

Quality control in the orthopedical diagnostics according to DIN EN ISO 9000 ff requires methods of nondestructive process control, which do not harm the patient neither by radiation nor by invasive examinations. To gain an improvement of health economy quality controlled and nondestructive measurements have to be introduced in the diagnostics and the therapy of human joints and bones. There is...

the aim of this study was to evaluate sound and decayed wood of iranianbeech (fagus orientalis) with a nondestructive stress wave method. wood samples,with dimensions of 9 by 19 by 200 mm were decayed in laboratory soil-bed tests,based on european pre-standard env-807. the decay was evaluated by measuringbending dynamic modulus of elasticity (moed) and longitudinal dynamicmodulus of elasticity ...

The three-dimensional(3-d) reconstruction and visualization of serials of industrial computed tomography(ICT) images is an important research aspect for large objects nondestructive detection. In the course of 3-d reconstructions of the continuous equidistant ICT images, the contour lines of every tomogram are picked out and joint by triangles in serialized order. After the stereo images of the...

Nondestructive testing (NDT) is an advanced and commonly used technique in tunnel engineering quality inspection. To achieve good application of nondestructive technology, its main inspection strategy analyzed, including the significance applying technology inspection, applied test analysis, analysis strategy. The analyses this paper are done hopes providing scientific reference for utilization...

Composite materials are often more practical in use for different military applications. These materials provide interesting results especially through their good strength properties, corrosion resistance and low specific weight. These materials have various structures. Any defect of these materials usually has a more complicated and other form than in metals and that is why methods and diagnos...

The majority of linear-optical nondestructive implementations of universal quantum gates are based on single-photon resolving detectors. We propose two implementations, which are nondestructive (i.e., destroying only ancilla states) and work with conventional detectors (i.e., those which do not resolve number of photons). Moreover, we analyze a recently proposed scheme of Wang et al. [J. Opt. S...

Large numbers of vibration signals of wood-based panels are unsteady and complicated, which means that detection can be difficult. The wavelet transform is an effective method to detect these signals, which are otherwise difficult to detect using the Fast Fourier Transform (FFT). This paper presents a study on nondestructive detection of bubble defects seen in poplar laminated veneer lumber (LV...
