✦ Synopsis

The possibilities of analysing coals on the microscale have been studied with statistical treatments. The effects, on the precision of microdetermination of ash, of particle size, sample weight, weighing error, vaporization of moisture from coal sample, and mixing of sample have been examined. A clear relation exists between theoretical considerations (e.g. calculation of numbers of particles needed for microanalysis from binomial distribution, separation of errors of taking increments, weighing and analytical procedure, etc.) and experimental results.

A specific oxidation method for estimating the valence states of carbon in coal is described. The method, which is also an important tool for more generally exploring the structure of coal, is based on the fact that sodium hypochlorite is a very selective oxidant capable of differentiating between S

Within the theory of belief functions Dempster's rule of combination is of particular importance for the integration of different bodies of evidence. In this article a set of axioms is presented that uniquely determines this rule. As the axioms reflect just the intuitive idea of partially moveable e
