The main aspects of charging electric cars from solar panels have been studied, namely from solar panels that have a rotating axis behind the sun, this allows for an increase in energy storage by 20-40%. Various technologies and systems for charging electric vehicles from solar panels are considered, including rooftop solar panels, mobile charging stations and other innovative solutions. The Дослідження технології використання сонячних панелей для зарядки електромобілів 171 environmental benefits of using solar panels to charge electric vehicles are highlighted, including reducing CO2 emissions and dependence on oil. The economic benefits are analyzed that pivot-axis solar panels have the potential to collect more solar energy because they are always aimed at the sun. While static panels standing still can lose some of their potential energy due to improper alignment. The financial benefits associated with the reduction of fuel and electricity costs, as well as the possibility of generating additional income through the sale of excess solar energy to the grid, were discussed. The technical challenges related to the efficiency of solar panels, charging capacity and energy storage are considered, as well as the directions of development of these technologies are predicted. The results of research into the process of charging an electric car from solar panels are described. It is shown that the best solar panels have an average efficiency of 20.5%, considering the number of sunny days in Ukraine, this is enough to use energy to charge a car. It has been established that for an average driver who drives about 15,000 kilometers per year, which is even higher than the average, to cover charging needs, about 2,700 kW is needed, which is about UAH 11,000 per year, which is very cheap for a car owner. Keywords: solar panels, electric cars, hybrid cars, recharging, renewable energy, environmental impact, rotating solar panels.

The problem of monitoring a computer network under conditions of limitations on the use of system resources and high requirements for the survivability of the monitoring system has been considered. An autonomous decentralized computer network monitoring system has been developed, consisting of a team of software agents. Each agent can operate in two modes: main mode and monitoring system management console mode. In the main mode, the agent collects information about the computer network. In management console mode, the agent provides the user with access to information collected by all agents and allows the user to execute commands to manage the monitoring system. The developed monitoring system allows you to obtain more reliable information about the operation of the network with greater efficiency under the conditions of limitations on the use of system resources specified by the user. The autonomous monitoring system is created on the basis of the concept of multi-agent systems, within which a software agent of the system has some initiative for planning and implementing monitoring scenarios. The operation of software agents implements methods for organizing adaptive processes for collecting information using the principles of self-organization and the concept of structural adaptation. A decentralized software architecture for an autonomous monitoring system without a control center has been proposed. This ensures high reliability and survivability of the monitoring system. The software architecture of the autonomous monitoring system implements the SMA application software interface and the corresponding software library, which allows you to collect statistical data on the operation of the computer network and its nodes. The implementation of a software agent and a management console for an autonomous computer network monitoring system has been considered.

我们考虑了在系统资源使用受限和对监控系统生存能力要求较高的条件下监控计算机网络的问题。我们开发了一个自主的分散式计算机网络监控系统，由一组软件代理组成。每个代理可在两种模式下运行：主模式和监控系统管理控制台模式。在主模式下，代理收集有关计算机网络的信息。在管理控制台模式下，代理可让用户访问所有代理收集的信息，并允许用户执行命令管理监控系统。在用户指定的系统资源使用限制条件下，开发的监控系统可以让您以更高的效率获取更可靠的网络运行信息。自主监控系统是在多代理系统概念的基础上创建的，其中系统的软件代理在规划和实施监控方案方面具有一定的主动性。软件代理的运作采用自组织原则和结构适应概念，实施组织自适应信息收集过程的方法。我们提出了一种用于无控制中心的自主监测系统的分散式软件结构。这确保了监测系统的高可靠性和生存能力。自主监控系统的软件架构实现了 SMA 应用软件接口和相应的软件库，可以收集计算机网络及其节点运行的统计数据。考虑了自主计算机网络监控系统的软件代理和管理控制台的实现。关键词：计算机网络监控、自主系统、分散控制、软件代理

This paper considers possible approaches to improving the quality of image signal formation both in the light and in the dark period of the day, as well as reducing the influence of noise, interference and artifacts on the characteristics of image signals. It is proposed to use the wavelet domain for the analysis of thermal and image signals with their subsequent possible complexation. The main features of the formation of such signals are indicated. It is shown that the proposed approach allows to improve the quality characteristics of image signals, especially in the dark period of time, as well as to ensure their effective processing related to filtering, compression, scaling and contrast change. A comparison of the obtained results of the proposed method with other existing similar signal processing approaches is given. Keywords – Thermal signals, video signals, complexation of signals, wavelet transformation.

The problem of choosing methods for tracking recognized objects in real-time for systems with limited hardware capabilities is considered. It was determined that for such scenarios, it is appropriate to integrate tracking methods into the device, bypassing data transmission via the Internet. Existing methods of tracking an arbitrary number of objects in real-time are considered. Among the performance evaluation metrics, the following were used: MOTA, MOTP, F1, MT, ML, ID, and FM. Based on the primary analysis of the effectiveness of such methods according to the metrics mentioned above, it was proposed to use the V-IOU tracking method to track recognized objects on a mobile platform in a mobile cyber-physical system. Key words: V-IOU, Arbitrary Object Class Tracking, Mobile Platform, Real-Time, MOTA, MOTP, Cyber-Physical System.

This work is devoted to the study of Smart Home systems based on the development of an energy optimization system for a smart home and based on various wireless communication protocols. The paper considers the construction of a home monitoring and control system based on the latest Bluetooth Low-Energy protocol using modern technologies. A device for monitoring and controlling electrical appliances, which is an element of this system, is proposed. The proposed architecture has advantages over other existing systems: reliability, performance, ease of deployment, and management. The system is flexible due to the possibility of selecting operating modes (automatic or manual) and changing various settings that affect the operation of the optimization algorithm. The paper presents examples of the system operation in different modes and at different values of the algorithm settings, consisting of a server deployed on a personal computer and two developed monitoring and control device prototypes. Keywords: smart home, energy consumption optimization, monitoring and control of electrical appliances, smart sockets, Bluetooth low energy.

In this paper, the author suggests a modification of the thread pool algorithm that was presented by Sean Parent at NDC London 2017. The suggested algorithm is as simple as the original implementation and demonstrates similar performance, while eliminating a potential drawback of the original implementation consisting in the fact that under certain circumstances, multiple tasks can be executed on the same thread, while other threads may be waiting for a task. The suggested idea consists in tracking the total number of tasks that are in the queues of the thread pool. When the main thread pushes a new task to one of the queues, the tasks counter is incremented. When a task is removed from the queue, the task counter is decremented. When a thread wants to get a task, it keeps checking the queues until it succeeds in getting a task from one of the queues, or until the tasks counter becomes equal to zero. When the tasks counter becomes equal to zero, the thread becomes idle until the counter becomes non-zero again. Then, one of the threads wakes up and starts checking the queues. An important point is to maintain even distribution of tasks in the queues since it has a significant impact on the performance of the algorithm. Keywords: multithreading, thread pool, task stealing.
