Theoretical and applied principles of the efficiency of aviation equipment restoration

The results of the enterprise's economic activity are multifaceted and depend on many factors. Under such conditions, it becomes more and more difficult to evaluate the obtained results of the enterprise activity. This is especially difficult to do in the aviation industry, since the complexity of aviation equipment and the tragic consequences of its malfunction significantly complicate the calculation of the economic efficiency of the aviation equipment restoration.

The essential characteristics of the basic concepts of the categorical apparatus for the economic assessment of aviation equipment restoration

The article is devoted to the study of the essential characteristics and interrelationship of the main concepts of the categorical apparatus of the economic evaluation of the restoration of aviation equipment. Peculiarities of the approach of various authors to the definition of the concept of aircraft repair are analyzed. It has been established what types of repairs are used during the operation of aviation equipment. The economic advantages and disadvantages of using various types of repair for aviation equipment are determined.

SMART SYSTEM FOR MONITORING WATER QUALITY PARAMETERS

Water is the most crucial factor for all living organisms, so it is essential to protect it. And water quality monitoring is one of the first steps required in the rational development and management of water resources. Smart systems used for real-time quality control and power consumption are rapidly developing. Their implementation in water quality assurance systems is essential and actual.

METHODOLOGICAL AND INVESTMENT SUPPORT FOR DEVELOPMENT INNOVATIVE POTENTIAL OF INDUSTRIAL ENTERPRISES

Purpose – The purpose of this study is to develop a strategy for improving the innovation of domestic industrial enterprises in modern conditions. The basis for solving this problem is a deep retrospective analysis of innovation in Ukraine in terms of investment sources and areas of expenditure on innovation of industrial enterprises.

DETECTION OF FALSIFICATION OF HORILKA BY ADMITTANCE SPECTROSCOPY

The methods of quality control of horilka by electrical parameters, in particular, dielectric constant, specific conductivity, and imitation components are analyzed. The research results of individual samples of alcohol solutions and horilkas of different brands by the method of admittance spectroscopy were also analyzed. Based on this, methods for detecting falsification of horilka products by the method of admittance spectroscopy are proposed. The reactive component of the control object's ad is selected as an informative parameter. Two types of falsification are analyzed.

State of the Art in the Production of Charcoal: a Review

The use of charcoal (CC) for various industries was analysed; the modern ideas about the factors influencing the process of obtaining CC were considered. The effect of raw materials nature (wood or agricultural wastes) and their characteristics (size, physical properties, chemical composition), as well as carbonization temperature, heating rate, oxygen level and pressure on the yield and quality of CC was described.

ASSESSMENT OF THE QUALITY AND THE LEVEL OF THE TECHNOGENIC LOAD ON THE SURFACE WATERS OF THE KHERSON REGION

The paper deals with the assessment of a surface water quality in the Kherson region, as well as the assessment of a technogenic load on the surface water bodies by the volumes of the wastewater and pollutants discharges over a long period of time. The problem of supplying the regions of Ukraine with water is urgent for many regions, including the Kherson region. The materials from the Regional reports, Ecological passports on monitoring a state the surface water as well as the data on the volumes of the sewage and pollutants discharges were used as baseline data.

Development of PI-controller optimal tuning method

Aim. The research aims to develop a method of optimal PI-controller tuning, which allows to take into account the constraints and to minimize the undesirable indicators of the automatic control quality. Method. In order to carry out the investigation, the problem of optimal PI-controller tuning was stated in a general form. The analysis of the elements of the problem has been conducted. It allowed substituting the elements to the requirements of individual minimization criteria.

IDENTIFICATION OF FRESH AND THAWED MEAT BY IMPEDANCE SPECTROSCOPY

The freshness of the meat is one of the indexes of its quality. However, it is often frozen to be transported and stored. After unfreezing, it is offered to a consumer as a fresh one. Quality of that meat is worse, but the price is, mainly, identical to the cost of meat that wasn’t frozen.
