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.
Nowadays research of psychomotor actions has taken a special place in education, sports, medicine, psychology etc. Development of computer system for psychomotor testing could help solve many operational problems in psychoneurology and psychophysiology and also determine the individual characteristics of fine motor skills. This is particularly relevant issue when it comes to children, students, athletes for definition of personal and professional features. The article presents the dynamics of a developing psychomotor skills and application in the training process of means. The results of testing indicated their significant impact on psychomotor skills development.
The article concerns the assessment of possibilities to increase the reliability of the rhinomanometry diagnosis using statistical characteristics of measured signals and corresponding differential pressure of an air flow in the nasal cavity during respiration. An original method for testing the patient's nasal breathing during forced inspiration has been proposed. It shows the influence of the space dimension of informative parameters on the diagnosis error probability. It has been proving that taking into account during the measurement experiment the dynamic modes in the operation of the diagnostic object, you can obtain the information redundancy that improves the reliability of diagnosis.
