1 Introduction In order to make better decisions related with crop production, precision agriculture practices information technologies to transport data from several sources, and it consists of three components: capturing data in an accurate manner
The precision of an activation analysis method prescribes the estimation of the precision of a single analytical result. The
adequacy of these estimates to account for the observed variation between duplicate results from the analysis of different
samples and materials, is tested by the statistic T, which is shown to be approximated by a chi-squared distribution. Application
of this test to the results of determinations of manganese in human serum by a method of established precision, led to the
detection of airborne pollution of the serum during the sampling process. The subsequent improvement in sampling conditions
was shown to give not only increased precision, but also improved accuracy of the results.
The errors of analysis due to the different parameters involved in 14 MeV neutron activation analysis method are studied. Formulae to calculate these erros have been developed when possible. Otherwise they have been evaluated for special experimental situations. Special cases where some parameters become critical, as far as precision is concerned, have been mentioned.
1 Introduction Providing high precision measurement of three-dimensional points coordinates in situ is crucial in many industrial applications. For achieving precision up to tens of micrometers, a Laser Tracker (LT) is often used. LT is a coordinate
The IAEA conducted the IAEA-CU-2006-06 Proficiency Test (PT) on “The determination of major, minor and trace elements in ancient
Chinese ceramic” in 2006. The results of this PT showed that of the 21 analytes reported by our laboratory 9 failed the precision
criteria. Therefore the results reported by our laboratory along with the results of other laboratories which carried out
analysis using neutron activation analysis (NAA) were studied. It was found that the major factor contributing towards data
falling in the “Warning” category, failing the precision criteria was the high uncertainties cited in the certificates of
the reference materials (RMs) used for quantification of data. In this regard, it is recommended that synthetic standards
should be prepared and used on a routine basis especially for the measurement of the elements K, Eu, Lu, Ta, Tb and Yb.
Four different approaches to PIXE data obtained in repeated measurements on thick standards have been evaluated in terms of precision and accuracy. Both were found to be the best when determinations relative to an external standard were normalized to a composition assumed to be 100% oxides.

The half-life of38Cl obtained by thermal neutron capture was measured to be 37.236±0.009 min. Values of the energy levels of38Ar from
– decay of38Cl were determined with a better precision than those available in the literature.
