The possibility of creating a computer control system for an unmanned aerial vehicle using remote cloud computing according to predefined scenarios from the user's desktop is investigated. For this, an experimental setup was created, which includes a quadcopter, a personal computer with the Windows operating system, an on-board computer Raspberry-3 with the Linux operating system, a Pi Camera V2 camcorder, and a Pixhawk autopilot. To model the control and transmission of video images the own control programs and photo pursuit on a computer Raspberry-3 in Python are recorded. Based on the obtained results, a model of unmanned aerial vehicle control from the desktop of the user's personal computer via the on-board computer without the use of a standard control panel and operator is proposed.

With the development of microprocessor components and, accordingly, a significant expansion of the use of computer technologies, remote measurement techniques are being developed. These include telemetry and remote control of technical systems or their components in industry, research, home appliances and other fields. In this paper, the author suggests how to build a local web-server based on a microcontroller with an ARM Cortex-M4 core, which can be interacted with via an http-browser with Internet access. The block diagram of the local web-server on the basis of the STM32F407 microcontroller with the ARM Cortex-M4 core is suggested. Hardware modeling of the local web-server with a two-processor architecture including the main controller and the Modbus processor with the RS-485 interface, which provides information exchange via the Modbus RTU protocol, is done. The main controller is equipped with an indicator system based on functionally programmable LED indicators, an LCD indicator of type BC1602A, a local keyboard, USB and SWD ports for debugging and programming of the microcontroller, an external Ethernet module providing a temperature sensor and the Modbus RTU relay module, which interacts with the main controller of the local web-server via the Modbus processor with the RS-485 interface using the Modbus RTU protocol. A software for interaction of the local web-server and a http-browser has been developed. The local web-server was tested with different types of http browsers, proved to be reliable and showed the response time which depends on the number of sensors and is less than 1 second in case of 9 sensors.

The article proposes methods for improving the structures of multi-bit multipliers, which are characterized by increased speed, reduced structural complexity of the device and reduced structural complexity of inputs and outputs depending on the bit multipliers (512-2048 bits), respectively (1024- 4096) times, compared with known multipliers based on classic single-digit full adders. Optimization of structures of multi-bit multipliers is offered. Comparative estimates of structural, functional and relative functional and structural complexities of their circuit implementations are given.

Consideration is given to enhancing storage security and maintaining data access control in cloud storage. Existing ways of controlling such access are analyzed. An enhancement of the encryption technique is proposed, based on the attributes of the ciphertext policy and its application in a decentralized data access management system in multi-user cloud storage systems. The main objective is to improve the security and privacy of the management of the cloud storage for which the existing management does not meet all the necessary requirements.

A neural circuit model of tracking control for unknown nonlinear dynamic systems is proposed. A first-order differential equation with variable structure and an output equation are used to describe the model. The model gives a possibility to reach a finite convergence time to working modes and limited tracking error. It does not need learning phase in offline mode. The model uses only outputs of the system and object to minimize tracking error of object trajectory. It has simple structure and can be used if internal dynamics and parameters of control system are unknown. Results of computer simulations of the model applications for optimal tracking control of rotation angle of two-link planar elbow manipulator confirming theoretical statements and illustrating its high performance are provided.

The Gao approach to construction of high order elements in arbitrary finite fields is to choose a convenient polynomial, which defines an extension of an initial prime field. This choice depends on one polynomial-parameter. That is why the mentioned approach can be considered as using of a finite field description with one degree of freedom. We explore in the paper the possibility of improvement of lower bound on element orders in finite fields of general form with using of two degrees of freedom. We have performed computer calculations in Maple environment, that would show possible winnings in this case, and given the correspondent results. Elements of high multiplicative order are used in a series of cryptographic primitives (Diffie-Hellman protocol, El-Gamal public
