The current state of poultry farming requires the development and application of modern technologies for daily young fledge. Young fledge of high quality guarantees the maximum profit of the production in case of its further growth. It is known that to obtain a healthy, high-immunity young fledge it is necessary to implement an effective process of the eggshell surface disinfection. Therefore, the search and development of highly efficient hatching egg disinfection technologies is an urgent task.
The work is aimed to research the process of synthesis and analysis of musical compositions. The main goal is to increase speed and quality of this process. This is done by combining sound analysis algorithms with music synthesis technologies. By this method music taken by the device microphone is processed by the mobile application and then transformed to the note sequence which could be edited by the user.
The structural scheme of the hydropulse device for strain hardening of materials is considered. Based on the block diagram of the device, its complete and simplified dynamic models are developed. On the basis of the dynamic model of the device and the scientifically grounded structure of assumptions, a mathematical model of the device was developed, the hydraulic link in which is presented as the Kelvin - Voigt body. For energy reasons, the choice of the force of the shock interaction of the piston - pulsator with the surface of the processed part is grounded. For energy reasons, the choice of the force of the shock interaction of the piston - pulsator with the surface of the processed part is grounded.
A spectral method for estimating the dynamic uncertainty of measuring instruments based on a mathematical model of the frequency characteristic of a measuring instrument and a model of the spectral function of an input signal is presented. The model equation for estimating the amplitude value of the dynamic measurement uncertainty is obtained, which is caused by the limited properties of the measuring devices when a measuring signal passes through it in dynamic operation modes. A mathematical simulation of the characteristic of the dynamic uncertainty variation during the passage of a measuring signal through a measuring transducer is performed using the dynamic model of a vibration transducer as an example.
