Planning under Sustainable Processes

The article presents the models used in the planning of production with unstable technology. This issue is becoming increasingly important for universities in connection with the transition of the Ministry of Science and Higher Education to the new principle of planning a state order for specialists, when the admission figures in the state assignment turn into release figures. For successful work in these conditions, universities are forced to change their system of planning for the training of specialists. The considered models are a proven tool for determining the size of the contingent and the necessary resources, which must be launched into the educational process in order to fulfill the state order by a given deadline.

Near-optimal state assignment in a finite state machine

In this research, the application of the Simulated Annealing algorithm to solve the state assignment problem in finite state machines is investigated. The state assignment is a classic NP-Complete problem in digital systems design and impacts directly on both area and power costs as well as on the design time. The solutions found in the literature uses population-based methods that consume additional computer resources. The Simulated Annealing algorithm has been chosen because it does not use populations while seeking a solution. Therefore, the objective of this research is to evaluate the impact on the quality of the solution when using the Simulated Annealing approach. The proposed solution is evaluated using the LGSynth89 benchmark and compared with other approaches in the state-of-the-art. The experimental simulations point out an average loss in solution quality of 14.29%, while an average processing performance of 58.67%. The results indicate that it is possible to have few quality losses with a significant increase in processing performance.

Structural Decomposition in FSM Design: Roots, Evolution, Current State—A Review

The review is devoted to methods of structural decomposition that are used for optimizing characteristics of circuits of finite state machines (FSMs). These methods are connected with the increasing the number of logic levels in resulting FSM circuits. They can be viewed as an alternative to methods of functional decompositions. The roots of these methods are analysed. It is shown that the first methods of structural decomposition have appeared in 1950s together with microprogram control units. The basic methods of structural decomposition are analysed. They are such methods as the replacement of FSM inputs, encoding collections of FSM outputs, and encoding of terms. It is shown that these methods can be used for any element basis. Additionally, the joint application of different methods is shown. The analysis of change in these methods related to the evolution of the logic elements is performed. The application of these methods for optimizing FPGA- based FSMs is shown. Such new methods as twofold state assignment and mixed encoding of outputs are analysed. Some methods are illustrated with examples of FSM synthesis. Additionally, some experimental results are represented. These results prove that the methods of structural decomposition really improve the characteristics of FSM circuits.

Improving Characteristics of LUT-Based Mealy FSMs with Twofold State Assignment

Practically, any digital system includes sequential blocks. This article is devoted to a case when sequential blocks are represented by models of Mealy finite state machines (FSMs). The performance (maximum operating frequency) is one of the most important characteristics of an FSM circuit. In this article, a method is proposed which aims at increasing the operating frequency of LUT-based Mealy FSMs with twofold state assignment. This is done using only extended state codes. Such an approach allows excluding a block of transformation of binary state codes into extended state codes. The proposed approach leads to LUT-based Mealy FSM circuits having two levels of logic blocks. Each function for any logic level is represented by a circuit including a single LUT. The proposed method is illustrated by an example of synthesis. The results of experiments conducted with standard benchmarks show that the proposed approach produces LUT-based circuits with significantly higher operating frequency than it is for circuits produced by other investigated methods (Auto and One-hot of Vivado, JEDI, twofold state assignment). The performance is increased by an average of 15.9 to 25.49 percent. These improvements are accompanied by a small growth of the numbers of LUTs compared with circuits based on twofold state assignment. Our approach provides the best area-time products compared with other investigated methods. The advantages of the proposed approach increase as the number of FSM inputs and states increases.

Unity and diversity turko-mongol world: Kultobe settlement as a crossroads of religions and cultures

The culture and art of the Turkic-Mongolian world is one of the deepest subjects of the humanities, which again and again take the attention of researchers. The historical vicissitudes, which was formed over many centuries, contributed to spread Zoroastrianism, Manichaeism, Buddhism, Christianity and Islam in the Great Steppe. We can see it in unique art artifacts and architectural structures. This article is devoted to unity and diversity study of the Turkic-Mongolian world, based on the example of the Kultobe settlement, which is presented by the authors as the oldest peculiar crossroads of religions and cultures. The Kultobe settlement, during scientific years and archaeological research by the Kazakh Research Institute of Culture, truly unique material evidence (architectural objects and artifacts) was discovered, which allows us to speak of this unique monument of archeology as one of the “crossroads” of religions and cultures in the Turkic-Mongolian world. The Kultobe settlement and later Yasi, a spiritual and religious place, developed -Turkic Sufism. The famous Sufi and poet K.A.Yasawi lived and preached here. The work was prepared under the state assignment of the Altai State University, project №748715Ф.99.1.ББ97АА00002 “The Turkic-Mongolian world of the “Greater Altai”: unity and diversity in history and modernity.”

On self-similarity of waves in tropical cyclones

<p>Wave fields generated by tropical cyclones (TC) are of strong interest for marine engineering, navigation safety, determination of coastal sea levels and coastal erosion. Considerable efforts have been made to improve knowledge about the surface waves in TC, both from measurements and numerical experiments. Full sophisticated spectral wave models certainly have the capability to provide detailed wave information, but they require large computer power, precise well-resolved surface winds and/or needs to consider large ensembles of solutions. In this context, more simplified but robust solutions are demanded.</p><p>This work is based on 2D-parametric model of waves evolution forced by wind field varying in space and time, non-linear wave interactions and wave breaking dissipation [submitted to J. Geoph. Res., see also preprint DOI: https://doi.org/10.1002/essoar.10504620.1]. Numerical solutions of model provide efficient visualization on how waves develop under TC and leave it as swell. Superposition of wave-rays exhibits coherent spatial patterns of wave parameters depending on TC characteristics, - maximal wind speed (um), radius (Rm), and translation velocity (V).</p><p>In this presentation we demonstrate how solutions of 2D-parametric model can be described analytically through self-similar functionsusing proper scaling involving the main TC parameters: um, Rm, and V. These self-similar solutions can be treated as TC-wave Geophysical Model Function (TC-wave GMF), to help analytically derive azimuthal-radial distributions of the primary wave system parameters (SWH, wavelength, direction) under TC characterized by arbitrary sets of um, Rm and V conditions. Self-similar solutions describe the main properties of wave field under TC, in particular: right-to-left half asymmetry of wave field under TC; strong dependence of wave energy and wavelength on V, um and Rm caused by group velocity resonance; division of TCs on “slow” and “fast” when TC-induced waves outrun TC and form wake of swell trailing TC.</p><p>Comparisons between self-similar solutions and measurements of TC-generated waves reported in the literature, demonstrate excellent agreement to warrant their use for research and practical applications.</p><p>The core support for this work was provided by the Russian Science Foundation through the Project №21-47-00038 at RSHU. The support of the Ministry of Science and Education of the Russian Federation under State Assignment No. 0555-2021-0004 at MHI RAS, and State Assignment No. 0736-2020-0005 at RSHU are gratefully acknowledged.</p>

Community of Hydrocarbon-Oxidizing Bacteria in Petroleum Products on the example of Ts-1 Aviation Fuel and AI-95 Gasoline

It has been shown that the studied petroleum products (kerosene and gasoline) contain microflocules of heterogeneous microbial biofilms, the cells of which are integrated into a polymer matrix containing acidic polysaccharides. Thirteen bacterial strains were microbiologically isolated from petroleum products, and their taxonomy was identified by the 16S rRNA sequence. Kerosene was characterized by a diverse bacterial composition including the following genera: Sphingobacterium, Alcaligenes, Rhodococcus and Deinococcus, while gasoline bacterial community included only two genera: Bacillus and Paenibacillus. Representatives of the Deinococcus genera capable of growing on the hydrocarbons were isolated from fuels for the first time. The strains isolated from gasoline (Bacillus safensis Bi13 and Bacillus sp. Bi14) proved to be the most effective biodegraders of all n-alkanes, isoalkanes, cycloalkanes, alkenes and aromatic hydrocarbons, whereas the kerosene strain Rhodococcus erythropolis Bi6 effectively decomposed n-alkanes and trimethylbenzene. Both types of petroleum products contained hydrocarbon-oxidizing communities, some members of which were more active in the biodegradation of hydrocarbons, while others were capable of producing biosurfactants and had either emulsifying activity (Deinococcus sp. Bi7) or cell wall hydrophobicity (Sphingobacterium sp. Bi5 from kerosene; Bacillus pumilus Bi12 from gasoline) significantly higher than the average level. The indicated properties of the studied strains make them promising for use in bioremediation. biodegradation, petroleum products, hydrocarbon-oxidizing bacteria, bio-surfactants The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic no. 10.5422.2017/8.9.). Investigation of microbial potential in the use hydrocarbons was supported by the Russian Foundation for Basic Research (RFBR), contract no. 18-29-05067. Physicochemical research was performed within the framework of the state assignment to the TIPS RAS

Antiviral Activity of Extracts from the Daedaleopsis confragosa F-1368 Basidiomycete

The antiviral activity of extracts of the basidial fungus Daedaleopsis confragosa (Bolton) J. Schröt strain F-1368 cultivated under the laboratory conditions has been studied. It was shown that the extracts obtained from 1 L of the culture contained proteins and polysaccharides in the amount of 71±5 and 413±15 mg/L of culture, respectively. Antiviral activity (ED50) against the pandemic influenza virus A/California/07/09 (H1N1)pdm09 was observed at extract concentrations in the range of 0.02-0.12 mg/mL depending on the culture medium. The therapeutic index (CC50/ED50) was at the level of 14-17, which makes it possible to recommend D. confragosa extracts for the development of antiviral agents. It was shown that treatment with hydrolytic enzymes (trypsin, zymolyase) leads to an increase in cytotoxicity and a decrease in the antiviral activity of the extracts. Daedaleopsis confragosa, basidomycetes, extracts, antiviral activity, influenza virus The study was carried out according to the state assignment to FBRI SRC VB «Vector», Rospotrebnadzor, Koltsovo.
