SIUI develops and manufactures a variety of ultrasound imaging systems and accessories for both human and veterinary use, and NDT equipment including phased-array ultrasonic flaw detector, [3] conventional flaw detector, [4] thickness gauge, probes [5] and accessories. The company is currently organized into three product category divisions ...
Probability of detection (POD) tests are a standard way to evaluate a nondestructive testing technique in a given set of circumstances, for example "What is the POD of lack of fusion flaws in pipe welds using manual ultrasonic testing?" The POD will usually increase with flaw size.
If the material contains a crack or flaw which make the spatial distribution of the electrical conductivity nonuniform, the path of the eddy currents is perturbed and the impedance of the coil which generates the AC magnetic field is modified. By measuring the impedance of this coil, a crack can hence be detected.

The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers. . Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is availa
The following is a list of Clarivate Citation Laureates considered likely to win the Nobel Memorial Prize in Economic Sciences. [1] Since 2024, thirteen of the 93 citation laureates selected starting in 2008 have eventually been awarded a Nobel Prize: Thomas J. Sargent and Christopher A. Sims (2011), Lars Peter Hansen and Robert J. Shiller (2013), Angus Deaton (2015), William Nordhaus (2018 ...
This study found that basic research played a key role in the development in all of the innovations. The number of basic science research [clarification needed] that assisted in the production of a given innovation peaked between 20 and 30 years before the innovation itself. While most innovation takes the form of applied science and most ...
The definitions provided in the Frascati Manual have been adopted by many governments and serve as a common language for discussions of science and technology policy and economic development policy. Originally an OECD standard, it has become an acknowledged standard in R&D studies all over the world and is widely used by various organisations ...
