    Development of a Telegram Bot for Receiving Data from OPC Servers
    (2021) Galkin, P.; Khmelik, O.
    It is important to develop programming of the embedded control system which allows the real-time system to change and actually program the built-in control system based on the PLC. Chatbot is a computer program developed on the basis of neural networks and machine learning technologies, which can be used to communicate in audio or text format , but chatbot can also be used to program embedded systems without changing the PLC program itself. The purpose of the work is to develop a chatbot in the Telegram service, which can be used to obtain information from embedded systems based on the OPC server and send the necessary information at the request of the user.

    Метод розрахунку радіусів отворів багатоелементного напрямленого відгалужувана
    (ХНУРЕ, 2023) Зайченко, Н. Я.; Коломієць, А. О.
    This work is devoted to directional couplers parameter calculation and verification by simulation in HFSS. The contradiction between the results of previous calculations and modeling is the problem of this research. A simplified method is proposed for calculating the radii of the holes of a directional coupler, which consists in central hole radii calculating, on the basis of the parameter of required coupling, which differs by using the Newton binomial coefficient, so the radius of the current hole is calculated as the radius of the central hole which is divided by coefficient. The coefficient is the cube root of the of the binomial polynomial numbers ratio, where polynomial numbers correspond to central and current hole. The cube root of number is a value which when multiplied by itself thrice or three times produces the original value.

    (ХНУРЕ, 2023) Світличний, М. С.
    Small dimensions and weight, economy, insensitivity to vibrations, etc. allow to attribute generators on avalanche diodes (GLPD) to number of the most promising sources of electromagnetic oscillations. Improvement of constructions and research of their properties generators, is a very relevant problem even nowadays. Of particular interest is the study of stability problems and adjustment of output frequency and power, synchronization of these generators, their electronic adjustment. Generators on avalanche diodes are used in radio relay lines, in systems of blind landing of aircraft, electronic height meters, stationary and portable radar stations.

    Методи протидії несанкціонованого доступу
    (ХНУРЕ, 2023) Світличний, М. С.
    Unmanned aerial vehicles (UAVs) typically carry sensitive data and equipment that may be at risk of unauthorized access or hacking. Unauthorized access countermeasures in UAVs include technical and procedural measures that help ensure security and protection against such attacks. Among the technical measures, one can note the encryption of data transmitted and stored on the UAV and the use of network protocols with security. Procedural measures include ensuring the physical security of the UAV, prohibiting access to equipment without appropriate authorization, and controlling the activities of personnel who have access to the UAV

    Методи проникнення у систему керування БПЛА
    (ХНУРЕ, 2023) Балай, А. Є.
    Unmanned Aerial Vehicles (UAVs), commonly known as drones, are used commercially, recreationally, and even militarily. However, the proliferation of UAVs has also raised new security concerns, especially with regard to hacking UAVs. A hacked drone can be used by an adversary for a variety of purposes, such as surveillance, sabotage, or to cause physical or material harm. A hacked drone can be redirected to veer off course or crash into a specific target, which can cause significant damage. In addition, information gathered by a hacked drone can be used to compromise sensitive data. Thus, it is critical for military individuals and organizations to take steps to protect against hacked UAVs and implement robust encryption and authentication protocols to avoid potential vulnerabilities.

    Расширение области применимости спектрального метода граничных интегральных уравнений для решения задач фотоники
    (ХНУРЕ, 2020) Ильяшенко, Л. Н.
    The work is devoted to the modern extension of classical method, that for a long time was not applicable to study state-of-art problems, while it provides fast and accurate solution. With this method electromagnetic transmission problem for Helmholtz equation is reformulated in terms of boundary integral equations (BIE). By means of parameterization BIE are reduced to those over a circle. It permits the singularity subtraction to calculate integrals numerically by using the simplest quadrature rules. The use of Fast Fourier Transform (FFT) which is based on trapezoidal rule gives rise to speed up calculations. With modern extension by conformal mapping approach not only ellipsoidal shapes but also other smooth closed boundaries and even polygonal shapes are amenable to investigation

    The Microwave Oven Thermal Field Uniformity Increasing by Using Powermeter
    (2019) Zaichenko, O.; Golovkina, L.; Miroshnyk, M.; Pahomov, Y.; Galkin, P.
    The microwave oven qualities improvement can be achieved, if use a powermeter. Extracting information about the passing power from the sensor signals in the powermeter can be performed by determining the passing power as a geometric mean of the sensor signals. The main advantage of this approach is ease of automation. The limitations of the passing power calculating algorithm as a geometric mean of two sensors signals are that mathematically rigorous expressions. It can be obtained only if two sensor signals are taken at the maximum and minimum of the standing wave. When the sensors was not placed in the maximum and minimum of the standing wave, the error appears. An amendment was made, and the non-excluded residual was estimated.

    (ХНУРЕ, 2019) Світличний, М. С.
    A smart home should perform many functions. If necessary, the owner may require different management scenarios and change their unlimited number of times. The idea of remote control and monitoring has always sparked the minds of those trapped in electronics and programming people. After all, the ability to at any time receive or send the necessary data, regardless of its location, provides ample opportunities.
