Uncertainty calculations in the certification of reference materials. 2. Homogeneity study,esults are then assumed to be representative of all remaining samples. An important aspect in this design is the translation of the characterisation data to a single sample, as usually the laboratory will be using only one sample of the batch. This form of homogeneity is very important and can be in

Uncertainty calculations in the certification of reference materials 3. Stability study,fter it has been prepared. This paper looks at the statistical aspects of stability testing. Essentially, these studies can be described with analysis of variance statistics, including variant regression analysis. The latter is used in practice for both trend analysis and for the development of expr

Some aspects of the evaluation of measurement uncertainty using reference materials,reference’, the ‘unbroken chain of calibrations’ and the “stated uncertainty”. For a certain chemical result, each of these aspects highly depends on the measurement uncertainty, both on its magnitude and how it was estimated. Therefore, the paper describes the experience of the Romanian National In

se Meitner and Fritz Strassmann led to the discovery that uranium nuclei bombarded by neutrons undergo spontaneous fission, releasing enormous energies. This work, conveyed to England and the US by scientific refugees from Nazi Germany, led to the instigation of the Manhattan Project and the develop

Rouvim Kadis undoubtedly will continue to grow in importance in the future..In this monograph, the authors investigate orthogonal polynomials for exponential weights defined on a finite or infinite interval. The interval should contain 0, but need not be symmetric about 0; likewise the weight need not be even.
