The book "A Beautiful Soul: Mathematician of the God" allows us to look at the past for a moment and, at least, brings us closer to the relationship between science and faith. The book describes the figure of Maria Gaetana Agnesi. She is commonly known as the author of one of the first integral calculus textbooks."Analytical Institutions for the Use of Italian Youth". Her name is called a crater on the moon and a comet. The curve witch of Agnesi takes its name from her name. We present a review...
We consider a sequence of independent random variables with the known distribution observed sequentially. The observation n is a value of one order statistics s : n-th, where 1 ≤ s ≤ n. It the instances following the n-th observation it may remain of the s : m or it will be the value of the order statistics r : m (of m > n observations). Changing the rank of the observation, along with expanding a set of observations is a random phenomenon that is difficult to predict. From practical reasons...
In this paper, originally published online in Mathematica Applicanda vol. 44(1) on 14 September 2016, the authors wish to state that there was an error in formulation of the optimality criterion at the beginning of the subsection 3.6.2. This is the part of the section 3.6 of the paper. In this errata the authors decided to add the general formulation of the optimality criteria in the subsection 3.6.1-2 and, to avoid misunderstanding, the entire the section 3.6 is reproduced with the complements...
