Inspired by recent advances in coverage-guided analysis of neural networks, we propose a novel anomaly detection method. We show that the hidden activation values contain information useful to distinguish between normal and anomalous samples. Our approach combines three networks purely data-driven end-to-end model. Based on target network, alarm network decides if given sample is normal. Thanks...

Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA) was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human healt...

SHISHIDO , S. and SUZUKI, T. Mercury in Human Hair: A Comparative Study by Using Two Different Methods of Atomic Absorption and Neutron Activation Analysis. Tohoku J. exp. Med., 1974, 113 (4), 351-356 Magos (1971) reported a new method of atomic absorption spectrometry for selective and simple determination of inorganic and organic mercury. To investigate the reliability of Magos's method, the ...

Multielements in a typical Japanese diet certified reference material prepared at the National Institute for Environmental Studies (NIES) of Japan, in collaboration with the National Institute of Radiological Sciences (NIRS) of Japan were determined by instrumental neutron activation analysis (INAA). Five samples (ca. 510-1000 mg) and comparative standards were irradiated for a short time (10 s...

some other “finish”, is widely used in determination of the total gold content of heavy-mineral concentrates. Direct instrumental neutron activation analysis (INAA) of the concenrate, which has the advantage of being a nondestructive multi-element technique, is also used. The objective of this study was to compare gold results obtained by the two methods on typical heavy mineral concentrates fr...
