The simplest, most reliable and sufficiently accurate method of dosing bulk products is batch dosing by volume using measuring containers. The article considers a mathematical model of a volumetric dispenser. The combination of several methods of regulating the supply of bulk materials during batch dosing is ensured by building an accurate model of the drum dispenser.

The Interventional Pressure (IP) between the orthosis and the foot in this study was measured using an engineered sensor device. When using orthotic devices to correct deviation of the foot or limb, it is often used to assess the importance and position of corrective forces. The components of the sensor device are: a 43.5 x 43.5 mm force sensor mat, an LCD display, connecting wires, and an Arduino. The system developed in this study is described as lightweight, easy to move, and inexpensive compared to other devices. This study made and programmed a sensor to measure pressure between the orthosis and the foot in three areas, and compared it to the F-Socket sensor. The experimental test was performed on a patient who suffered from instability of the right leg at the ankle joint. In the posterior, lateral and medial regions, the interventional pressure between the tibia and the orthosis was calculated in two ways. The 1st method uses the sensor manufactured in this study (SCR), while the 2nd method uses the F-Socket sensor. The test results showed that the pressure readings obtained from the fabricated device were close to the results obtained using the F-Socket device.

The high share of manual labor in forestry does not allow solving modern problems facing the Russian forest industry. The introduction of new machines and technologies using the achievements of modern science and technology is required. In order to identify the prospects for the use of robotic systems for solving reforestation problems, existing machines and technologies were studied, the results and experience of using both successful existing solutions and solutions under development were summarized, and, using elements of system analysis, new design solutions were found for the layout of the robotic platform and the landing module to it.

Recently, the main principles in the field of municipal solid waste management are recycling and reuse of secondary resources. Information technologies are widely used in modern waste management technologies. Problematic is the issue of recognition of the sorting object on the waste conveyor. There are various robotic systems for automated separation of sorting objects. The article provides a description of the system in the process of "recognition - capture - movement" of a sorting object on a common conveyor. A group of sensors is used to identify objects on the conveyor, while simultaneously fixing the coordinates of each identified object on the surface of the conveyor belt. Information about the coordinates and properties of each identified object is transmitted over the communication line to the control panel by manipulators, which capture individual identified objects and mix them into special containers.

In this paper, the authors attempt to consider ethnographic approaches to the study of language policy issues, in detail, with an emphasis on various angles of modeling the language situation in the traditional and innovative ethnographic paradigm. The paper also provides a strong case for the effectiveness of this approach in measuring. forecasting and designing the ideal and real language situation in the regions which are of interest to the researcher. A number of examples are presented that convincingly illustrate the potential of ethnographic modeling. The authors are the first to present the opposition of the emic perspective to the ethical one, which has found its graphic embodiment in the model proposed by the authors. Moreover, the ethnographic model is an ideal tool for monitoring feedback when studying the functioning of closed forms of language policy, as well as for tracking various consequences of practical measures in the field of language.

Keywords: ethnography, ethnographic model, emic and ethical perspectives, critical ethnography, micro-ethnography, sociolinguistic ethnography, closed and open forms of language policy

Hybrid space solar power stations with laser light emission, using inexhaustible energy of the Sun, provide environmentally clean energy, "green", as well as the development of space solar energy, which is a promising and relevant direction of energy system development in space (providing electric power to space equipment) and in the Earth energy system. Introduction of wireless energy transfer in the form of laser light makes it possible to focus the laser beam safely and with the least losses by semiconductor laser in the range of 0.55-0.75 µm or 1.0-1.1 µm windows of atmospheric transparency (Stage 1) followed by development of efficient fiber lasers with solar pumping at the same wavelength (Stage 2). The three variants of the solar energy transmission process from the Sun to the user in hybrid space solar power plants make it possible to provide electricity to underdeveloped and inaccessible regions without cable power transmission networks (areas in the Russian Far North, Central Siberia, Canada, Greenland, the Arctic and Antarctica, mountainous areas, deserts, natural disasters, disasters and continental shelf areas), as well as mobile, mobile transport and "smart grid" systems.
