Influence of Low Temperature Nitrocarburizing Modes on the Structure and Properties of Х12ф1 Steel
No full textIn the article, the influence of low-temperature nitrocarburizing on the structure and properties of Х12Ф1 steel was considered. It was found that for Х12Ф1 steel the highest values of micro-hardness are achieved at a saturation temperature of 550 °С and amount to 12,000 MPa at a four-hour saturation
Algorithms for Synthesis of Adaptive Decentralized Control of Interconnected Systems by The Speed Gradient Method
No full textSynthesizing algorithms of decentralized adaptive control for a class of interconnected systems with nonlinear local dynamics and uncertainty are considered, ensuring the stability of isolated subsystems of the entire system, taking into account interactions. When connected to a stable isolated subsystem, the system's stability may be violated and the objective function will cease to be a Lyapunov function for a system with connections. Very strong connections can significantly change the dynamics of the system, and the behavior of subsystems in an isolated state will be radically different from the behavior in a coupled system. Therefore, the law of control of a complex system, which ensures only the stability of isolated subsystems, cannot guarantee the stability of the entire system considering interactions. At the same time, to solve the problem of taking into account the interactions of subsystems, an adaptation algorithm based on the speed gradient method was introduced into the general control law. The results of the numerical analysis confirmed their effectiveness, which allows them to be used in solving applied problems of synthesizing systems for decentralized adaptive control of technological objects

Разработка Методов Получения И Использования Новых Эффективных Коагулянтов Из Отходов Производств
No full textДанная работа относится к технологии неорганических веществ. Она может быть использована при получении алюминийсодержащих коагулянтов. С их помощью предложены методы обработки сточных вод промышленных предприятий, а также ливневых вод, содержащих нефтепродукты. В данной работе представлены конкретные примеры результаты исследований по очистке природных, производственных и нефтесодержащих сточных вод с использованием новых ОХА полученных по новой технологии. Дана оценка эффективности действия коагулянтов-флокулянтов ОХА на модельных и реальных природных и промышленных сточных водах. Произведено сравнение новых композиционных материалов с широко применяемыми для этих целей известными аналогами, коагулянтами - сульфатом алюминия и железным купоросом. Дана оценка эффективности действия коагулянтов-флокулянтов алюминийсодержащих коагулянтов на реальных промышленных сточных водах
Using Voice Guidance, an Intelligent Walking Assistance Mechanism for the Blind
No full textThis study develops a perfect blind stick that may be used by the sight handicapped to feel their way around and find things. This study suggests a high-tech blind stick, which, with the help of enhanced equipment, enables visually impaired people to move around with relative ease and take a break, if necessary. The stick features a GPS, Bluetooth, a foldable seat, and an ultrasonic sensor. Our proposed model uses ultrasonic sensors that emit ultrasonic waves ahead of it to detect obstacles. When an obstacle is detected, the sensor relays that information to a Raspberry Pi 3, which then processes the information and calculates how close the obstacle is. If the Raspberry Pi 3 detects an impending danger, a buzzing sound will be issued. The circuit does not react if the identified barrier is too far away. The GPS system on the stick can be used anywhere. The Raspberry Pi 3 will vibrate as a warning if the detected obstacles are within a safe distance. The stick also has a capability that lets the user feel how much light is in a certain area. The blind individual can locate the stick without any difficulty. A remote is fitted with a button for this function. The stick's buzzer can be activated via remote control, making it easier for the blind person to locate it. In an emergency, a GPS module can be used to get to a certain location and contact a specific person by text message. The advanced blind stick also features a tripod support at its base, allowing the visually impaired to extend the stick and unfold it into a seat. The hardware of the system consists of a microcontroller and various sensors, including a proximity sensor and a ping sonar sensor. The stick's handle has been redesigned to fold out into a flat seating surface when not in use
Teaching Intercultural Competence: Approaches, Methods, and Techniques
No full textThe current article deals with the approaches, methods, and techniques which require individual information about a particular culture, besides the presence of skills empathy, tolerance, and reflection. There are definitions of intercultural competence, where key positions are focused on the ability phenomenon. Translators help people overcome language barriers, dispel their suspicion and serve as a bridge in intercultural communication. Listening, observing, evaluating: using patience and perseverance to identify and minimize ethnocentrism, seek out cultural clues and meanin
Development of Technology to Increase the Evenness of Parts Made of High Manganese Steel
No full textMechanical engineering consists of a number of technological processes in manufacturing enterprises, forming a kind of technological chain. This chain is closely related to the working unit of each unit and the working quality of the machines before it. Taking this issue into account, it can be concluded that the influence of technological chain equipment on the quality indicators of machinery manufacturing enterprises and heavy industrial products is great. Therefore, the more efficient operation of the technological equipment of machinery manufacturing enterprises and heavy industry without distortion depends in many respects on the strength of their details. This requires the study of the process of operation of the details, which are mainly rubbed with each other
