У статті оцінено вплив на якісні показники варених ковбасних виробів параметрів технологічного процесу приготування фаршу: тривалості кутерування, температури кутерування, а також досліджено вплив способів приготування фаршу на функціонально технологічні показники модельних систем та якісні показники варених ковбасних виробів. Встановлено, що вищими органо-лептичними та фізико-хімічними показниками характеризувались варені ковбасні вироби, виготовлені за запропонованими раціональними параметр...

The free vibrations of circular cylindrical shells with various thickness-to-midsurface radius ratios and different combinations of clamped and hinged edges of the shell are studied using the finite element method. The dependence of the natural frequency vibrations on the increase in the shell thickness is analyzed. The symmetric and asymmetric modes of free vibrations, frequencies, and modes of the vibrations corresponding to bending, torsion, tension-compression, and shear deformations are ...

The study aimed to create a digital twin for the integration of control and diagnostics of electromechanical systems under conditions of uncertainty, with minimal reliance on physical sensors. The research was conducted at Mykolaiv National Agrarian University. Physically based models were developed for thermal processes in windings, assessment of losses in magnetic conductors, and wear indicators for components, virtual sensors, signal filtering algorithms and degradation prediction were imp...

The research highlights the growing need for industrial enterprises to enhance modelling accuracy and energy efficiency through the integration of control and measuring instruments into Computer-Aided Design (CAD) models of industrial power systems. The study explores the feasibility of using CAD systems to integrate these instruments, focusing on their metrological accuracy and impact on the reliability of digital models and energy management. A classification analysis of instruments based o...

The aim of the study was to substantiate the effectiveness of an intelligent system for automated design of energy-efficient facilities in the agro-industrial complex (AIC) with integrated diagnostics of electric drives. The methodology included experimental testing of asynchronous electric motors, numerical modelling, and optimization. Data analysis was performed using Student's t-test, analysis of variance, and principal component analysis. The results showed that in faulty electric motors,...
