Satoshi Nakamoto mentioned the Bitcoin as a combinational integration of e-signatures. which can also be called “blockchain". The blockchain creates a chance for bitcoin transfer among users without a need for third parties (financial institutions). The illustration of the blockchain usage can be exemplified with the Bitcoin in Figure 1. The reason behind why the e-currencies are called "ciyptocurrencies” is that blockchains such as Bitcoin utilizes cryptography to regulate the transactions. Balance of the Bitcoin users are secured with a private key. The legal permission for transactions is given by a group of users known as “miners", they benefit from sharing database and distributing processing and receiving additional bitcoins in exchange. -
Сегодня спрос на мономеры, которые являются основным сырьем при производстве высокомолекулярных соединении и полимеров, очень высок. В частности, из года в год растет спрос на мономеры, содержащие винильную группу, включая акриловую кислоту, акрилонитрил, винилацетат, винилхлорид и т.д.[1].

Comparisons the numerical results of the turbulence model for the problem of rotating tubes inside a dynamic hydrocycloneThe article provides a comparative analysis of turbulence models by numerically simulating a swirling flow inside a rotatable pipe. To solve this problem, the Reynolds averaged non-stationary Navier-Stokes equations in a cylindrical coordinate system were used. To find the Reynolds voltage, the turbulence model was used the most popular semi-empirical turbulence model. Comparison is made between models of different approaches to turbulence SSG / LRR-RSM-w2012 and νt-92. The numerical results obtained on the basis of turbulence models are compared with the well-known experimental results of Reich and Beer (1989)

Digital economy is a system of implementation of economic, social and cultural relations based on the use of digital technologies. It is sometimes referred to as the internet economy, the new economy, or the web economy. The digital economy is not some kind of economy that needs to be created from scratch. This means moving the existing economy to a new system by creating new technology, platforms and business models and implementing them into everyday life. First of all, the digital economy significantly increases people's living standards, it is the main cause of corruption and "black economy". Because numbers seal everything, store it in memory, provide information quickly when needed. Under such conditions, it is impossible to hide any information, make secret deals, or not provide full information about this or that activity. -

FORMATION OF A DATABASE OF ROAD SIGN WARNINGS USING THE OBJECT RECOGNITION ALGORITHM
Entrepreneurship and PedagogyTimely detection and recognition of road signs is very important for motorists and pedestrians. The necessary information is delivered to the driver through the program of direct recognition of road signs. There are different types of road signs, some signs may have multi-directional points to indicate the direction of the location, and some signs are about safety rules and restrictions. can do in the message. Identifying and recognizing road signs is an important practice because it helps the new driver to find the way. We are able to solve these problems through the road sign detection program we created in python. In this program, in the following model, each pixel in the binary matrix is 8 bits, so instead of converting their values to 0 and 1, they can be converted to values between 0 and 255. In this way, 128x128 pixel images are converted into binary matrices, and these matrices are prepared for high-level data acquisition models, for example, the CNN model.
