Influence of Boris V. Gnedenko’s Probabilistic-Statistical School on the Development of Cybernetics and Informatics

Boris V. Gnedenko (1.01.1912–12.25.1995), a distinguished scientist and pedagogue and Academician of AS of UkrSSR (at present, the National Academy of Sciences (NAS) of Ukraine) lived and worked in Ukraine for 15 years (1945–1960) and created a world famous scientific school in probability&statistics. The author of this article who is a pupil of this school, a disciple and a coauthor of B. V. Gnedenko, an employee of the V. M. Glushkov Institute of Cybernetics since 1971, and an Academician of NAS of Ukraine notes the influence of the contribution of B. V. Gnedenko and his most prominent disciples V. S. Mikhalevich, K. L. Yushchenko, V. S. Koroliuk, T. P. Maryanovich, and others on the formation of cybernetics and informatics.

Creating a document workflow for example scientific organizations

Development methods of workflow for electronic document management systems (EDMS) in scientific organizations were proposed. The main forms of documents in scientific organizations were discovered. The generalized classification of documents according to their types and subtypes was created.The appropriate keywords for each document category were discovered. EDMS subsystem distribution was completed, their functions and purpose were highlighted. Based on the built architectures of EDMS separate subsystems, the generalized EDMS architecture of scientific institutions was proposed.This is the architecture of the flow (workflow) of scientific and technical papers of electronic document management system that takes into account the use in scientific institutions. Design and implementation of EDM under the proposed architecture and techniques allow more efficient use of EDMS in scientific organizations. It should be noted the following:1. Not all of EDF, present on the market today have sufficient flexibility to implement the proposed techniques and architecture.2. The question of increasing the EDMS efficiency in scientific organizations after implementation of the proposed architecture requires additional study.In addition, the maximum effect can be achieved by implementing a standardized EDMS in scientific organizations of all levels, ranging from the National Academy of Sciences of Ukraine (NASU ). In this case, all the scientific workflow in the country will be paperless, will facilitate scientific cooperation between scientific organizations and all levels of scientific management institutions of NAS and make it transparent for users. Sending e-mails will be performed using standardized procedures and protocols of interaction

Data-computing technologies: A new stage in the development of operational oceanography

An analysis is given of the methods of operational oceanography based on measurements derived from satellite data, observations acquired by drifters and passing vessels, and modern simulations of marine and oceanic circulations. In addition, a historical review is conducted of the previous and current research in this field carried out in the Soviet Union, Ukraine, and Russia. A discussion is given of the principles underlying the design of an effective data-computing system (DCS) for solving the problems of operational oceanography and the implementation of the prototype system for the Black Sea within the joint research project of the Russian Academy of Sciences (RAS) and the National Academy of Sciences of Ukraine (NASU) “The Black Sea as an Ocean Simulation Model.” The effectiveness of applying the multicomponent splitting method in the construction of sea circulation models and specialized DCSs with integrated algorithms of variational assimilation of observational data is estimated. The concept of using the Black Sea as a testing site for innovations is developed. The underlying idea of the concept is the similarity of the Black Sea dynamics with processes in the oceans. The numerical Black Sea circulation models used in the project are described, their development areas are discussed, and the requirements to a Black Sea observing system are defined.

OH 1720-MHz lines as tracers of bipolar outflows in the vicinity of Class I methanol masers

A sample of Class I methanol masers (MMI) has been surveyed at 1720 MHz to search for possible associations between MMI and 1720-MHz OH masers, which should be formed by the same collisional pumping mechanism. If the model for methanol masers is correct, the sample should contain a statistically significant number of 1720-MHz OH masers at the positions of MMI. The observations were conducted on the 70-meter radio telescope of the National Academy of Sciences of Ukraine (NASU). The results show that ∼50% of 72 MMI are associated with OH emission at 1720 MHz. In many sources, strong absorption lines are also observed. In most cases, the OH (1720) lines are narrow (linewidths of <2 km/s) suggesting they may be maser lines. The OH column densities obtained from Gaussian fitting of these narrow OH lines are, on average, 1.5 × 1017 cm−2. TheH2 density in the emitting medium reaches 107 cm−3 if the region of the OH (1720) emission has been subject to interaction with a bipolar-outflow front. This is sufficient to excite MMI, and the presence of narrow, possibly masing OH (1720) lines at the MMI velocities indicates the likely presence of shocks from bipolar outflows in the vicinity of the maser condensations, supporting models in which these molecules are collisionally pumped.
