Amur State University (Russian: Аму́рский госуда́рственный университе́т) is a university in Blagoveshchensk, Amur Oblast, Russia. is closely associated with the history of the Amur Region. Blagoveshchensk Technological Institute was founded on the basis of Blagoveshchensk Technical Faculty in 1975. At that moment it was the first institute of light industry in the Far East. In 1992 Blagoveshchensk Technological Institute was renamed into Blagoveshchensk Polytechnical Institute. Two years later the Polytechnical Institute developed into a full-fledged multidisciplinary university; the Amur State University..
The article synthesizes a system of combined control of a class of nonlinear-nonstationary multi-mode plants operating under conditions of structural-parametric uncertainty and different types of delays (neutral delay and state delay). A procedure for complete (structural and parametric) synthesis of a control system is proposed. Firstly, based on the hyperstability criterion, $\boldsymbol{L}$-dissipativity conditions, as well as the use of filtercorrectors (setting and output) and an implicit reference model, a structural synthesis of the combined control system is carried out. Structural synthesis includes four key stages: presentation of a mathematical model of the control system in deviations, solution of two positivity problems, and verification of the fulfillment of control purposes. Secondly, with the help of a genetic algorithm, automatic selection of the coefficients of the developed control system is performed by minimizing the criterion of the generalized work - parametric synthesis. The efficiency of the synthesized control system is demonstrated at the simulation stage in the Matlab development environment, Simulink package.
The current paper investigates L1-induced interference patterns in manifestation of unstressed vowels in the Russian speech of a female speaker of the Ust-Nyukzha local Evenki accent. The subject pronounced words containing unstressed allophones expressed in spelling by letters “е”, “а”/“я” and “о”. The material was processed using auditory and acoustic analyses. It was found that due to the difference between Russian and Evenki phonological systems expressed in vowel harmony and weakly-centralizing stress in the latter, there was the absence of standard vowel reduction that triggered the realization of wrong allophones and the absence of standard phoneme changes or wrong phoneme changes. 38% of unstressed vowels demonstrated the absence of phoneme /e/ reduction in pretonic and post-tonic positions. When proceeded by soft consonants, in 63% of all unstressed positions, phoneme /ɑ/, instead of standard /i/ substitute, lacked reduction displaying the features of stressed /ɑ/ after soft consonants. When preceded by /ʧʲ/, /ʃʲ:/, /j/, unstressed vowels displayed the phoneme /e/ pattern instead of the standard /i/ pattern accounting for 13% of all unstressed instances. After hard consonants, 82% of first pretonic vowels, due to the lack of quality reduction, displayed [ɑ] allophone characteristic for stressed position instead of the standard reduced [ʌ]. There were very few instances (0.05%) of the absence of phoneme /o/ reduction. In all other instances its quality was reduced following the standard pattern that resulted in the standard /ɑ/ substitute. The obtained results demonstrate interference manifesting itself for two out of the three unstressed vowels in separate words.
The scientific article examines the socio-economic problem of unused agricultural land, which hinders the socio-economic development of rural areas, limits employment growth, hinders the formation of the income base of municipalities and the effectiveness of the use of regional resource potential. The authors have analyzed scientific approaches to the problem of unused land. Modern digital methods for conducting a continuous rapid survey of arable land are compared, which have replaced the traditional ones, and given the scale of the number of plots that need to be put into circulation during the implementation of the state program, maximum automation of surveys and assessments is absolutely necessary. A set of measures to involve unused agricultural land in the turnover is being gradually revealed. Pilot projects are given as an example, one of which has a target for the involvement of arable land for 2026. Suggestions are given on the expediency of including lands in the list of objects to be involved in regional agricultural turnover.
Archimandrite Palladius (Pyotr Ivanovich Kafarov, 1817-1878) was a clergyman of the Russian Orthodox Church, a participant in the 12th and the head of the 13th and 15th Beijing Spiritual Missions, and one of the founders of Russian academic Oriental studies. Archimandrite Palladius's knowledge and experience allowed him to become the head of the ethnographic expedition of the Russian Geographical Society to the Amur and South Ussuri regions. One of the results of this expedition was his diary, “Travel Notes on the Route from Beijing to Blagoveshchensk via Manchuria in 1870”, which is a unique source on the geography, ethnography, social, political, and economic life of northern and northeastern China during the late Qing period. Based on these notes, an attempt is made to reconstruct the elements of China's religious landscape during this period. Kafarov's observations of the presence of Buddhist and Taoist shrines and religious structures, such as obo, which maintained ties with the region's shamanic past, the worship of natural objects (mountains), zoolatry, and the overall religious and syncretic nature of beliefs, indicate the close interethnic interaction and the interpenetration of religious beliefs in the cultures of the peoples living in northern and northeastern China during the late Qing Empire.
The article proposes a solution for developing a steam pressure control system in the common steam main of the Blagoveshchensk Thermal Power Plant with automatic selection of parameters based on a genetic algorithm. A possible steam output of a boiler control option at a power plant is described. It involves the interconnected operation of five key components: the main controller — the upper-level control system; the heat load controller, mill loading controllers, primary air and air mixture controllers — the subordinate control loops. The main controller operates under conditions of significant uncertainty and impacts the performance of the entire heat and power generation system. The mathematical model of the control plant was obtained using a passive experiment based on an annual data on the operation of the BKZ(E)-420-140 boiler. The control plant can be represented by a system with a constant delay, changing parameters and structure in various operating modes, with a relative degree of the transfer function greater than or equal to unity. In this article we implement a procedure for the complete synthesis of the control system using: two equivalent filter-correctors — a setting and an output one, an implicit reference model, an adaptive-robust control algorithm synthesized based on hyperstability criterion (at the structural synthesis stage), and a genetic algorithm (at the parametric synthesis stage). At simulation the performance of two control algorithms was compared: the developed adaptive-robust control algorithm and the classical proportional-integral control algorithm.The results obtained in this article can be used to ensure the efficiency of large thermal power systems.
