Information technology for detecting armed people is proposed and its software implementation is investigated. The YOLO convolution neural network was used to detect objects in real time. The Python programming language and the PyTorch library were used to develop the neural network. A program designed to detect armed people in a video stream has been created, the functionality of which allows classifying the type of recognized weapon.

Myoelectric control of bionic prostheses is an important field of research in the field of rehabilitation. Intuitive and intelligent myoelectric control can restore upper limb function. However, much research now focuses on the development of various myoelectrical and biotechnical control methods, limiting research to the complex daily tasks of prosthetic manipulation, such as grasping and releasing. The article examines the latest advances in the research areas of bionic prosthesis management. In particular, attention is paid to the methods of determining movement intentions, classification of discrete movements, estimation of continuous movements, single-channel control, feedback control and combined control. Motor neurons group input signals from the central nervous system that affect muscles and form motor units. The electromyography (EMG) signal, which is obtained by recording motor neuron action potentials, reflects muscle activity. This signal, oscillating within ±5000 μV with a frequency of 6 to 500 Hz, reflects the characteristics of muscle contraction. Depending on the location of the sensors, EMG signals are divided into intramuscular and surface electromyography. Intramuscular electromyography provides an accurate study of muscle activation, but requires the implantation of sensors, which can lead to physical problems. EMG, which captures a signal from the surface of the skin, is easier to use and is widely used in experiments with myoelectric prostheses.

In the article a bidirectional reflectance distribution function based on a polynomial of the third degree is developed. The main disadvantages of Schlick, Phong, Blinn reflectance models are analyzed. The approximation of Blinn-Phong model by a cubic polynomial is proposed to improve the productivity of three-dimensional image formation. Formulas for the coefficients of the approximation cubic polynomial are calculated. The disadvantages of using the proposed cubic polynomial for reproducing the glare’s attenuation zone are considered. A function for high-precision reproduction of this zone is proposed, formulas of its coefficients are calculated. A combined function, combining a cubic polynomial for reproducing the glare’s epicenter zone and a function for reproducing the attenuation zone, is proposed. The plot of the combined function is built. It is shown that the combined function reproduces the glare’s epicenter and attenuation zones with small relative and absolute errors. The developed reflectance model provides a highly-productive formation of three-dimensional scenes in computer graphics systems. The proposed distribution function of surface reflectivity can be used in computer graphics systems.

The article developed an improved simulation model of the propagation of photons in scattering biotissue based on the Monte Carlo method, which allows comprehensive consideration of all the main optical processes that occur during the propagation of optical radiation through BT. On the basis of the developed statistical model, simulation modeling of photon propagation processes in the skin and its separate layers was carried out, which allowed to establish the scattering and transmission characteristics for each of the skin layers with model parameters taking into account the angles of incidence of radiation in the visible and near-IR ranges, the thickness of the skin layers. Also, the simulation made it possible to determine the relative intensity of scattered photons depending on localization.

The article develops an intelligent system for identifying the user's trust rating, which allows viewing information about contacts that are more aimed at creating trust in the interlocutor or providing information that helps to identify the caller or the person with whom we are trying to contact. The k-nearest neighbours method was chosen to create the recommendation system. The main advantage of using the k-nearest neighbours method is the ability to take into account the unique trust rating of each phone number. It is important not only to find phone numbers with a similar rating, but also to take into account the approximate rating. The k-nearest neighbours method allows you to provide recommendations based on the similarity between phone numbers that have received positive feedback from users with similar preferences. Intelligent recommendation systems can provide phone numbers with similar ratings. When a user requests information about a phone number associated with fraudsters, the system instantly offers low-rated phone numbers that are therefore potential fraudsters.
这篇文章开发了一个智能系统，用于识别用户的信任等级，从而可以查看有关联系人的信息，这些信息的目的更多是为了让对话者产生信任感，或提供有助于识别来电者或我们试图联系的人的信息。我们选择 k 近邻法来创建推荐系统。使用 k 近邻法的主要优点是能够考虑到每个电话号码的独特信任度。重要的是，不仅要找到具有相似评级的电话号码，还要考虑到近似评级。K 近邻法可以根据从具有相似偏好的用户那里获得积极反馈的电话号码之间的相似性来提供推荐。智能推荐系统可以提供评级相似的电话号码。当用户请求提供与欺诈者有关的电话号码信息时，系统会立即提供评级低的电话号码，这些电话号码因此也是潜在的欺诈者。

For the first time, the results of an integrated approach to the treatment of diseases caused by herpesvirus infections with severe pain syndrome, which consists of a combination of protocol treatment and laser therapy, have been proposed and demonstrated. Using laser therapy allows you to: reduce the dose of medications to overcome pain, and then completely abandon them; significantly reduce the intensity and duration of pain; avoid side effects, first of all, such as allergic manifestations, which are an urgent problem in the treatment of lesions of the peripheral nervous system.
