Suppose that a random variable X of interest is observed perturbed by independent additive noise Y. This paper concerns the “the least favorable perturbation” Yˆε, which maximizes prediction error E(X−E(X|X+Y))2 in class Y with var(Y)≤ε. We find characterization answer to this question, and show example it can be surprisingly complicated. However, special case where infinitely divisible, soluti...

⎯This paper presents a solution for optimal business continuity, with storage architecture for enterprise applications, which will ensure zero data loss and quick recovery. The solution makes use of Internet protocol storage area network (IPSAN), which is used for data management without burdening the application server, as well as mix of synchronous and semi-synchronous replication techniques ...

Recently, smart port systems connected to autonomous ships have attracted increasing interest. Thus, an intelligent system can automatically berth create system. To ensure the safety of large moored in open coastal terminals, which are often subjected bad weather such as strong winds, it is necessary calculate and evaluate their mooring security on a case-by-case basis. In this study, capacitie...

An analysis of optical echelle spectra towards nine stars in the Cep OB4 association is presented. Interstellar absorption lines which arise in the (1, 0) and (2, 0) bands of the CN A 2Π – X 2Σ+ red system towards BD+66◦ 1661, BD+66◦ 1674, and BD+66◦ 1675 are used to infer accurate CN column densities N(CN). A comparison with earlier measurements in the CN violet system allows to infer a CN Dop...

⎯Video tracking is a complex problem because the environment, in which video motion needs to be tracked, is widely varied based on the application and poses several constraints on the design and performance of the tracking system. Current datasets that are used to evaluate and compare video motion tracking algorithms use a cumulative performance measure without thoroughly analyzing the effect o...

In 1661, Kaspar Schott published his comprehensive textbook "Cursus mathematicus" in Würzburg for the first time, his "Encyclopedia of all mathematical sciences". It was so successful that it was published again in 1674 and 1677. In its 28 books, Schott gave an introduction for beginners in 22 mathematical disciplines by means of 533 figures and numerous tables. He wanted to avoid the shortness...
