This paper studies the notion of similarity with reference to situations of situation theory. While the commonsense notion of two situations resembling each other appears to be valuable in our daily life, we show that it is problematic for the same reasons researchers have been pointing out in psychological and philosophical literature. That human beings can u e the notion naturally (without mu...

On the basis of previous theoretical and practical research conducted by author, in this paper concept pedagogical situation is studied. The suggested classification situations based on ability a to solve tasks, reach problems, achieve effect thus become event. these as well logic practice teacher's everyday work, three types were previously identified. One type described paper. goal such unach...

using qcd factorization for the hadronic matrix elements, we show that existing data, inparticular the branching ratios br ( b →j/ψk) and br ( b →j/ψπ), can be accounted for in this approach.we analyze the decay b j /k( ) within the framework of qcd factorization. the calculation of therelevant hard-scattering kernels for twist-2 and twist-3 is completed. we calculate this decay in a special...

Data envelopment analysis (DEA) is a method for measuring the relative efficiencies of a set of decision-making units (DMUs) that use multiple inputs to produce multiple outputs. In this paper, we study the measurement of DMU performances in DEA in situations where input and/or output values are given as imprecise data. By imprecise data we mean situations where we only know that the actual val...
