Scan based transition tests are added to improve the detection of speed failures using scan tests. Empirical data suggests that both data volume and application time, for transition test, will increase dramatically. Techniques to address the above problem, for a class of transition tests called “enhanced transition tests”, are proposed. The first technique, which combines the ATE repeat capabil...
پوششهای tbc یکی از جدیدترین و پیشرفته ترین پوششهایی است که امروزه در توربینهای گازی نیروگاهها و توربینهای هواپیماها استفاده می شود. این پوششها با ایجاد اختلاف دما در حدود 100 تا 150 درجه سانتیگراد، باعث افزایش عمر سوپرآلیاژهای قطعات داغ و نیز باعث صرفه جویی چشمگیری در مصرف سوخت نیروگاهها و هواپیماها می گردد. در این تحقیق، بحث و بررسی در مورد علل تخریب پوششهای tbc در لاینرها و قطعات transition p...
nowadays, organizations to success in global competition, to provide new and qualified products and services and employment of versatile workforce, in context of new public management, have restructured through reengineering, downsizing, and outsourcing processes. however, these developments have caused changes in psychological contracts, employment relationships and transition from permanent e...
We investigate volume phase transition in gels immersed in mixture solvents, on the basis of a three-component Flory-Rehner theory. When the selectivity of the minority solvent component to the polymer network is strong, the gel tends to shrink with an increasing concentration of the additive, regardless of whether it is good or poor. This behavior originates from the difference of the additive...
In this research. The magnetic phase transition and anisotropic magnetoelastic effects of a polycrystalline sample of Nd14Dy2Fe78B6 were studied by susceptibility and magnetostriction measurements. The composition was prepared by casting method. SEM pictures and XRD analysis showed that it was composed of polycrystalline magnetic phases with the main phase of 2-14-1. Results of ac susceptibil...
