У сучасному світі число пристроїв, підключених до інтернету речей (IoT), стрімко зростає, що породжує нові виклики у сфері забезпечення їхньої безпеки. Стаття присвячена розробці моделі безпеки для IoT пристроїв, яка враховує обмежені обчислювальні ресурси і мінімальне енергоспоживання, необхідні для ефективного функціонування криптографічних алгор...

A review of methods and instrumentation for the study of tribological and mechanical properties of the surface. It is established that the most common methods for studying these properties in the micro and nano-ranges are contact methods based on the interaction of the hard tip with the material under study. In scanning probe microscopy, a bimorph...

The paper presents the technique of calculating the fluctuations of the container with the working mixture. Available methods for investigation of the vibroprocessing are insufficient for the practical use. Additionally, for further use of research material for the grounded design of the technological process of vibrational processing in industrial...

In the article, the critical analysis of the current state of processing of vibrating methods of grinding, the advantages of their existing methods of processing machine parts and devices with traditional grinding are indicated. The inspection of the developed vibration installation, the influence of the regime of vibrating on the movement of the w...

The article presents the experimental results of the regularities of circulating vortex motion of the working environment and displacement of the body of the vibrobunker at its symmetric shock-impulse load. It is found that the shock-impulse load on the vibrobunker leads to the occurrence of a slow circulating movement of the working environment, w...

Various aspects of the methods of physical and physicochemical modification of components of filled thermoplastic composite materials are analyzed, aimed at improving the surface properties of the fillers and the technological properties of the polymer matrix during their interaction. It is noted that the improvement of the interfacial interaction...
