Development of k0-INAA standardization method by neutron activation with Am-Be source.
The k(0)-standardization method on the (241)Am-Be isotopic neutron source has been studied and developed. In this paper, the characteristics of the neutron spectrum in an isotropic neutron field of (241)Am-Be isotopic neutron sources was experimentally determined by dual monitor method using measured cadmium ratios of (197)Au(n, γ)(198)Au and (98)Mo(n, γ)(99)Mo(β(-))(99m)Tc reactions. Applicati...
متن کاملSubdivision Method Applied for Oiml Weights Using an Automatic Comparator
According to International Recommendation OIML R 111, [1], the weights of nominal values greater than 1 g may have a cylindrical shape with a lifting knob. Taking into account this kind of shape and that in the case of an automatic comparator, with the maximum capacity of 1 kg, the diameter of weighing pan is quite small for placing a group of weights from 500g to 100g, the subdivision method...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

متن کاملINAA - Fluglärm-Monitoring am Flughafen Frankfurt (INAA - Flight and noise monitoring at Frankfurt Airport)
Abstract INAA – flight and noise monitoring at Frankfurt Airport visualizes flights and measures of noise made around Frankfurt airport. It calculates emissions of single flights and displays height profiles of arriving and departing planes. So-called “flight doors” describe no-flight-zones for noise abatement. They show in a three-dimensional way how planes are within horizontal and lateral li...
