The aim of this article is to attempt a concise review of the state of the art of the nondestructive biomarkers approach in vertebrates, establishing a consensus on the most useful and sensitive nondestructive biomarker techniques, and proposing research priorities for the development and validation of this promising methodology. The following topics are discussed: the advantages of the use of ...
By the uncertainty, the common Nondestructive quantitative testing data could not meet the needs of the basic request of Nondestructive evaluation and reliability safety analysis in actual engineering. In this article, used the uncertainty evaluation method, the regress analysis and the fuzzy theory, the soft calibration method was built for uncertainty of measurement of nondestructive quantita...
کارکرد مناسب و مطمین یک قطعه کار فرزکاری شده در سیستم به شدت به شرایط سطحی آن بستگی دارد زیرا سطح ماشین کاری شده خوب باعث افزایش مقاومت شکست، مقاومت خوردگی و عمر خزش آن می گردد. یکی از مشخصات مهم سطحی قطعه کار تنش پسماند می باشد. تنش پسماند در قطعات و اجزاء مکانیکی به تنشی گفته می شود که حتی بعد از برداشتن نیروهای خارجی در درون قطعه باقی می ماند. سالانه هزینه های زیادی صرف تنش گیری قطعات مختلف ...
Human factors are among the main elements affecting the reliability of nondestructive examinations (NDE). In a man-machine system, human reliability is affected by many factors (performance shaping factors) whose influence on reliability cannot be easily expressed quantitatively. This paper identifies and ranks 59 perform-ance shaping factors by using a fuzzy reasoning method and proposes a pro...

The paper considers the ways and methods of determining strength wood according to current norms rules. required number samples are tested compared with characteristics in SP 64.13330.2020 “Wood structures”. It is concluded that it impossible use obtained results for calculations building structures, due lack coefficients norms, taking into account vices scale factor. existing nondestructive co...
ultrasonic testing (ut), a nondestructive testing (ndt) method, is under development for quality determination of agricultural products, although it has long been used in the food industry. determination and measurement of product quality are important in modern agricultural research. noninvasive/nondestructive quality determination is a novel aspect of the postharvest process in which paramete...
