The necessity of developing digital technologies for managing biotechnological processes in long-term agrocenoses based on cognitive modeling is substantiated. Methodological approaches to the construction of effective management tools for biotechnological processes based on the logical concept of the triad (organization, management, efficiency) in a dynamic cycle have been developed. An algorithm for the formation of digital technologies for managing biotechnological processes is proposed, including: the formation of multifunctional databases and data banks and digital applications, cognitive modeling of system relationships and the formation of cognitive maps, the development of a system architecture of a prototype program, approbation and verification of the adequacy of a digital application. An algorithm has been developed for constructing cognitive models for the formation of management tools for biotechnological processes in long-term agrocenoses, including clarification of goal setting and local tasks; the distribution of functional relationships between the structural components of the agrocenosis using methods of correlation and regression analysis; economic and statistical characteristics of systemic relationships in reproductive processes by functional areas of influence using correlation matrices and discriminant analysis; verification of the results of optimization of parameters of functional stability and technological and economic efficiency of production and technological processes. A cognitive process management map is constructed using the example of protecting fruit plantations from pests. A flowchart of an algorithm for building a digital control program for biotechnological processes for protecting fruit plantations is proposed using the example of an apple moth, which provides for the development of a technology for importing data from a weather station to determine the sum of effective temperatures and determine the start of processing depending on the stage of development of the pest; neural network technologies for detecting a harmful object; a module for automated selection of a protection system.

ОРГАНІЗАЦІЯ ВНУТРІШНЬОГОСПОДАРСЬКОГО КОНТРОЛЮ В АГРАРНИХ ПІДПРИЄМСТВАХ ТА ЙОГО ВДОСКОНАЛЕННЯ

The article discusses the features of organizing on-farm control in agricultural enterprises. To begin with, we examined the development of the agricultural sector in Ukraine in recent years and the impact of the war on it. It was the agricultural sector that proved to be the most resilient during the war and supported the economy of our country in more difficult times. It has been studied that the agricultural sector in Ukraine is developing at a rapid pace, which is why it is necessary to use and implement an effective system of on-farm control. The Ukrainian government should develop the agricultural sector and focus on building effective government programs to stimulate exports and maximize government support. Next, we analyzed the essence of on-farm control over the interpretations of various scientific researchers and determined the most appropriate interpretation, in our opinion. It has been determined that on-farm control is a system of methods and procedures carried out by company management in accordance with current legislation and internal regulations, contributing to the improvement of production and economic activities and the high-quality implementation of management decisions and job responsibilities by employees. For agricultural companies, on-farm accounting is extremely important, because management needs to monitor all business processes, which start from the purchase of materials and end with the sale of finished products. As a result, we proposed an electronic digital control program "Digital Company", which should help optimize costs in all business processes and departments of agricultural enterprises. Without organizing effective work of on-farm control, it is impossible to achieve the implementation of any socio-economic development strategy for the future. In addition, it should be noted that on-farm control, acting as a source of information, largely makes it possible to determine the adoption of management decisions. Therefore, on-farm control acts as a significant element of the economic security system in agricultural enterprises, and the "Digital Company" electronic management system we propose will allow you to quickly see a holistic picture of all business processes of an agricultural enterprise.

A Visitor’s Hybrid Smart Guide Control System

Modern industrial society is filled with hybrid systems. The effectiveness of a control system is now a basic requirement in any institution. In general terms, hybrid systems are reactive systems that intermix discrete and continuous control components in which the discrete part of that control system makes the decision on behaving for the whole designed system and further decides if it can allow it to switch to another set of control protocols when appropriate conditions are availed. The continuous part only functions according to a specified protocol. Hybrid systems are common models used in digital (logic) and continuous networks and devices. Digital control programs detect, control, and supervise continuous and discrete systems using differential or difference equations. This principle was utilized in our design and reported thereof. Although this work developed a different method to deal with specific problems facing students at Technical University of Mombasa. An upgrade was recommended so as to extend the control system to the eye- impaired students and visitors. Since the issue of optimal smart control systems cannot be ignored in the design of new control systems with today's requirements in our learning institutions, it was concluded that further research was necessary to bring about a fully reliable and well-developed control system able to use real-time and real routes as they exist at the university ground. This work reports a hybrid control guide system designed and implemented at the Technical University of Mombasa.

Theorem-Proving Analysis of Digital Control Logic Interacting with Continuous Dynamics

This work outlines an equation-based formulation of a digital control program and transducer interacting with a continuous physical process, and an approach using the Coq theorem prover for verifying the performance of the combined hybrid system. Considering thermal dynamics with linear dissipation for simplicity, we focus on a generalizable, physically consistent description of the interaction of the real-valued temperature and the digital program acting as a thermostat. Of interest in this work is the discovery and formal proof of bounds on the temperature, the degree of variation, and other performance characteristics. Our approach explicitly addresses the need to mathematically represent the decision problem inherent in an analog-to-digital converter, which for rare values can take an arbitrarily long time to produce a digital answer (the so-called Buridan's Principle); this constraint ineluctably manifests itself in the verification of thermostat performance. Furthermore, the temporal causality constraints in the thermal physics must be made explicit to obtain a consistent model for analysis. We discuss the significance of these findings toward the verification of digital control for more complex physical variables and fields.

Research on the Model of Business English Translator Training Based on DRM Control Model

With the development of economic globalization, the cultivation of business English Translators should follow the principle of compound talents training mode and improve the overall quality of the talent of business English translators. Business translation training plan has shortage of teaching content and lacks cross-cultural communication training program.

Modernized setup for studying the interaction of ions with energies to 40 keV with the surface

A modernized setup for studying the ion-surface interaction is briefly described. The main ion channel implemented on the “Large MEPhI mass monochromator” with an ion energy range of 1–40 keV makes it possible to obtain ion beams with (EM/Z) ≤ 4000 keV × a.m.u. Operation with intermediate-energy hydrogen ions allows obtaining information on the thickness of layers of atoms with masses differing from substrate atoms, by analyzing energy spectra of protons scattered from two- or three-layer targets. The use of new digital power units and relevant control programs also allows automation of the ion beam control and makes it possible to perform ion-beam experiments using preliminarily developed irradiation programs.

Discrete-time control for rectangular hybrid automata

Rectangular hybrid automata model digital control programs of analog plant environments. We study rectangular hybrid automata where the plant state evolves continuously in real-numbered time, and the controller samples the plant state and changes the control state discretely, only at the integer points in time. We prove that rectangular hybrid automata have finite bisimilarity quotients when all control transitions happen at integer times, even if the constraints on the derivatives of the variables vary between control states. This is in contrast with the conventional model where control transitions may happen at any real time, and already the reachability problem is undecidable. Based on the finite bisimilarity quotients, we give an exponential algorithm for the symbolic sampling-controller synthesis of rectangular automata. We show our algorithm to be optimal by proving the problem to be EXPTIME-hard. We also show that rectangular automata form a maximal class of systems for which the sampling-controller synthesis problem can be solved algorithmically.

Development of the HIDEC Inlet Integration Mode

An integrated flight propulsion control mode called Inlet Integration has been developed and will be flight demonstrated on an F-15 test aircraft in the Highly Integrated Digital Electronic Control (HIDEC) program. The HIDEC program is conducted by the NASA Ames/Dryden Flight Research Center. The development of the Inlet Integration mode is described in this paper, including the Inlet Integration concept, the control law, its implementation on the test bed aircraft, and the predicted performance benefits. The Inlet Integration system will increase excess thrust (thrustdrag) during supersonic operation. This improvement in aircraft performance is accomplished by utilizing a calculation of engine corrected airflow from the Digital Electronic Engine Control (DEEC) to improve the scheduling of the inlet ramp positions in real time. The improvement in scheduled ramp positions will result in increased inlet performance, hence aircraft performance, while maintaining stable inlet operation. Analyses have shown the Inlet Integration system can increase excess thrust by as much as 13 percent at Mach 2.3, 40,000 ft. This thrust increase will result in increased supersonic acceleration. Inlet integration has the additional feature of improving aircraft supportability by eliminating the need for replacing inlet controllers when higher thrust derivative engines are installed in the F-15.

Processor-Controlled Microdensitometry

A new scheme of densitometric data collection is described which comprises a digital filtering technique and process control program. A 6502-based PET 2001/32K microcomputer and an Elscan model 2500 specular microdensitometer are interfaced through the standard 6522 VIA port chip. An Analog Devices ADC80/12 monolithic A/D converter is used to digitize the analog output of the light photometering system. Additionally, control of the optical scanner assembly is provided through processor-driven 4-phase TTL logic circuitry. The technique applies to any analog signal of interest, either for filtering purposes or for recording directly into memory for later waveform or transient analysis. The maximum data gathering rate is 40 kHz, limited by the A/D conversion time of 25 μs.

Tracking system simulation with variable delay

This paper describes the analog simulation developed to evaluate a digital control program. The digital pro gram is a doppler prediction program which updates a ground transmitter so that the input frequency to an airborne transponder is held constant. It describes the simulation of the transmitter, re ceiver, transponder and the air-to-ground links be tween the transponder and the transmitter and re ceiver. One of the unique features of the simulation is the dynamic time delay between the transponder and its ground stations. The simulation is an example of direct modeling of the real-time transfer functions.
