Introduction (problem statement and relevance). One of the most promising and intensively developing directions in the automation field of road transport management is the creation of highly automated vehicles.The purpose of the study was to find a way to solve a wheeled vehicle safe automatic braking problem in terms of minimizing quality control of the quadratic functional and work out optimal software and hardware implementation of this system.Methodology and research methods. To solve the problem, the method of the control algorithm analytical design was used, basing on the use of the necessary conditions for minimizing the elements of the functional for the control law synthesis. The maximum deceleration value was due to the identified tire grip, and the deceleration threshold from which braking begins was selected as the minimum of the working deceleration and two decelerations depending on the rear obstacle distance.Scientific novelty and results. The tests of the developed function were carried out for the LADA Vesta vehicle equipped with an ABS valve body with the possibility of programmed control. The analysis of the research results showed that when solving the problem of safe automatic braking in front of an obstacle, the software limitation of braking deceleration did not allow wheel blocking and performed the functions of an anti-lock braking system at the permissible wheel slipping level; software backup of the distance calculation to the front obstacle from the moment of braking start allowed to prevent most of the situations with false data from the radar when the vehicle pecked during braking.Practical significance. Software tuning of mathematical models parameters of the engine, transmission and braking system allows you to adapt the automatic braking system to a wide class of vehicle models.

The popularity of Korean pop culture in the world can be considered an exceptional phenomenon of 2020. One should note that processes reflecting the effective interaction of state structures with the spheres of the creative industry in the modern economy have a special scientific potential at the moment. These creative industry spheres include art, cinema, animation, music, game development and software products. The most successful case in this area is the developed system of cultural media export in South Korea. Research into the economic opportunities of creative industries as a new stage in modern society is becoming a practically significant way to solve the problems of increasing the country's economic power in the Digital Age. The experience of South Korea is still insufficiently covered in Russian research. The practical significance of research in this field is associated with the study of the use of cultural products as a tool for economic growth.

Introduction. The use of the method of full-scale-mathematical modeling in “real time” opens up wide opportunities associated with the analysis of the modes of operation of the “man – vehicle – environment” system, as well as the study of the loading of units and assemblies of vehicles. The existing research complexes of full-scale mathematical modeling are suitable for obtaining most of the indicators usually determined by full-scale tests. The difference lies in the ability to fully control the course of virtual testing, recording any parameters of the vehicle movement, taking into account the “human factor”, as well as complete safety of the experiment. Purpose of research. The purpose of this work is to create a mathematical model of the dynam-ics of a wheeled vehicle, suitable for use in such a complex of full-scale mathematical modeling and assessment of the load of transmission units in conditions close to real operation. Methodology and methods. The proposed model is based on the existing model of the dynamics of a wheeled vehicle developed at Bauman Moscow State Technical University. Within the framework of the model, the dynamics of a vehicle is described as a plane motion of a rigid body in a horizontal plane. The principle of possible displacements is applied to determine the normal reac-tions of the bearing surface. The interaction of the wheel with the ground in the plane of the support base is described using an approach based on the “friction ellipse” concept. To enable the driver and operator of the full-scale mathematical modeling complex to drive a virtual vehicle in “real time” mode, the mathematical model is supplemented with a control system that communicates between the control parameter set by the driver by pressing the accelerator and brake pedals and the control actions of the vehicle's transmission units, such as: an electric machine, an internal combustion en-gine, a hydrodynamic retarder and a brake system. The article presents a block diagram of the de-veloped control algorithm, as well as approbation of the system's operation in a complex of full-scale mathematical modeling. Results and scientific novelty. A mathematical model of the dynamics of a wheeled vehicle was developed. It opens up wide possibilities for studying the modes of operation of the “driver-vehicle-environment” system in “real time”, using a complex of full-scale mathematical modeling. Practical significance. A mathematical model of the dynamics of a wheeled vehicle was devel-oped. It is supplemented with an algorithm for the distribution of traction / braking torques between the transmission units, which provide a connection between the driver's pressing on the accelerator / brake pedal and the control parameters of each of the units.

Anti-Lock Braking Systems (ABS) have been developed and integrated into vehicles since it is invented more than thirty years ago. However, most of nowadays ABS are designed for multi-wheeled passenger cars, commercial cars and trucks. Due to the technical complexity and additional cost, ABS is not as common on two-wheeled vehicles, such as motorcycle, electric scooter, electric bike, etc. Study shows that injuries and deaths in relation to two-wheeled vehicles with ABS are significantly decreased. This paper is to provide a brief review of the state-of-the-art on the ABS configuration of two-wheeled vehicles.

Modern vehicle dynamics in its broadest sense encompasses all forms of vehicles. It aims to improve the riding comfort and the maneuverability for high-quality automobiles. This paper develops a sensor-based fuzzy controller (SFC) with a composite anti-lock braking system and tracking control system (ABS/TCS) to navigate escaping motions of wheeled vehicles under the assumption of Coulombs viscous friction and lumped-mass/rigid-body motions. The so-called escaping dynamics of wheeled vehicles occurs when the vehicle escapes from the constrained space during braking or cornering. Traditionally, such slippage phenomenon is usually ignored because of its high frequency and strong nonlinear features. The proposed SFC is designed to shorten braking distance under emergent circumstances and minimize cornering radius to improve maneuverability for wheeled vehicles. Finally, detailed simulations of wheeled vehicles with a composite ABS/TCS under the assumption of Coulombs viscous friction are used to justify the SFC algorithm.

In the moment of complete engagement in any activity, we function without conscious thought—referred to as ‘the zone.’ Digital technologies, from mobile devices to the Internet, can be a constant source of diversion; however, can digital tools help us get into the zone more quickly rather than simply distract us? Using open-source software and hardware, I have developed a real-time data visualization and sonification that have been recorded as performances on the website Mind & Matter, the project accompanying this paper. The performances are filmed in different locations and the visualization geolocates these locations, comparing them to the cell towers within the area. The project seeks to show waves within and around our body that are normally invisible. Each performance seeks to train both my brain and body to find stillness within. The paper is informed by the communications theorists and artists studied throughout the Communications and Culture program. I seek to answer Catherine Malabou’s question of “What We Should Do with Our Brains,” and how we might find agency in our brain plasticity though technological extension.

Abstract The problem of determination of threshold values of changes in stability characteristics of a river displacement ship is studied. A model and a data preparation scheme are being developed for the algorithmic implementation of the construction of curves of threshold values of lateral stability characteristics until the moment corresponding to the command given by the ship’s captain to bring life-saving appliances to a state of readiness or to use them. For the case of flooding of two adjacent hull compartments of a three-deck river passenger motor ship under the action of an external static inclining moment, illustrating data of calculations of hydrostatic characteristics and ship trim are presented, and an ensemble of diagrams of its static stability with threshold values is built. The results of the studies performed are intended for the software and hardware implementation of a digital system for active monitoring of the ship’s hull condition, predicting the development of a dangerous situation, supporting decision-making by the captain of a river vessel on the use of standard rescue equipment in the event of the threat of the ship being flooded and overturned.

Formulation of the problem. At present, in the conditions of the development of trade, international transportation is becoming more significant. However, despite this, insurance of civil liability to the customs authorities with the use of the International Road Transport Book in the Republic of Belarus shows a negative trend. The purpose of the research is to explore the features of civil liability insurance to customs authorities using the International Road Transport booklet in the Republic of Belarus and analyze its dynamics, as well as to identify possible trends in its development. The object of the research is the features and practical procedures for voluntary insurance of civil liability to customs authorities using the book of International road traffic in the Republic of Belarus. Methods used of the research. The use of the induction method allowed us to designate ways to improve the procedures for voluntary insurance of civil liability to the customs authorities. The hypothesis of the research. The negative tendency of civil liability insurance to customs authorities is partly related to restrictive conditions, under which the carriage of goods under the International Road Traffic System can be carried out. The statement of basic materials. The Convention on International Road Transport defines the carriage of goods carried without intermediate transshipment in road vehicles, their compositions or containers, crossing one or more borders, from the customs of departure to the customs of destination, provided that a certain part of the International Road Transport operation between its beginning and end is made by road. Goods transported in accordance with the International Road Transport Procedure are exempt not only from paying or depositing in the intermediate tariffs of import and export duties and taxes, but also from customs inspection in them. Originality and practical significance of the research. The procedure for the operation of civil liability insurance to customs authorities with the use of the International Road Transport booklet, taking into account the UN Customs Convention on the International Carriage of Goods, is disclosed. Conclusions of the research. Insurance organizations of the Republic of Belarus increase the demand for insurance of civil liability to the customs authorities using the book of International road traffic and popularize it among residents of the country. This will contribute to the development of not only the insurance market in the country, but also the maintenance of the status of the Republic of Belarus as an export-oriented country.
