Society has always paid great attention to the problem of human behavior that does not comply with established social and generally accepted norms. Recently, interest in the problem of deviations in human behavior has increased significantly. Today, the study of deviant behavior is an interdisciplinary problem that is being solved within the framework of various scientific disciplines. Recognition of anomalies in human behavior is a complex and currently undisclosed research problem. In the process of identifying behavioral anomalies, the recognition of emotions by various signs plays a leading role. In order to increase the accuracy of the results, it makes sense to perform a comprehensive assessment of emotions on several signs at once, such as facial expression, posture, vocal signs (intonation, speech speed, etc.). The article presents existing algorithms and methods for recognizing emotions. The rationale for the choice of software product development tools is given. The functional requirements for the application are presented in the form of a diagram of use cases in UML 2.0 notation. The architecture of an Android application for recognizing anomalies in human behavior in the form of diagrams of components and classes of the conceptual level is shown. Prototypes of the user interface are demonstrated.

The analysis of the frequency-controlled drive currently used on the technological equipment of the Volgogradneftemash enterprise is presented. Taking into account the peculiarities of the pumping and ventilation equipment installed at the enterprise, the principles of regulation are determined and the influence of a frequency-controlled drive on the quality of electrical energy is evaluated. The negative influence of the frequency-controlled drive of ventilation and pumping equipment on individual indicators of electricity quality was noted. In order to reduce this influence, an energy-saving device has been proposed for installation. The issues of the possibility of using an energy-saving device at the facility are considered, as well as an analysis of its efficiency during operation from the point of view of improving the quality of electricity in the internal power supply system of the Volgogradneftemash open Joint stock company is carried out. The use of the device is an effective solution, since it leads to high energy efficiency of technological equipment by reducing current surge, suppression of higher harmonics and electromechanical interference.
