quality control

The principle of device operation for determining the quality control of diesel fuel is considered, which helps to
investigate the spectral characteristics of diesel fuel. Basic wavelet transformations are given. IR spectroscopy of diesel fuel from
different producing countries was carried out, and determination of the cetane number through wavelet coefficients and determining
conclusion diesel fuel quality were performed.

A brief description of the basic stages of image processing is given to pay attention to the segmentation stage as a
possible way to improve efficiency in decision-making. The main characteristics of the presented model are visual signs, such as
color, shape, the presence of a stem, and others. Due to the different approaches in image processing, a high level of truthfulness is
achieved, which is expressed in the percentage ratio of the accuracy of decision-making and varies in the range from 90 to 96%.

 In the article, both the test method features and the test results of research of thermal behavior of steel fragment were analyzed. Two types of test conditions for steel construction material were considered. The definition and main features of measurement techniques were presented. Fire retardant material test results for steel plates with hydrogen combustion shown the limit of fire resistance of the tested samples is more than 30 min. The main advantages and disadvantages of the test were determined. The positive and negative aspects of this approach were analyzed.

Adopting socially responsible management practices of the organization promotes greater awareness in decision-making, based on a better understanding of society's expectations, anticipation of risks, and opportunities. Responsible management of an organization can improve its relationships with stakeholders. Encouraging compliance with regulatory obligations leads to decisions that are more likely to gain the support and trust of those who implement them and who they influence. The result can be improved risk management practices and improved reputation.

Clinical laboratory diagnostics (laboratory medicine) is one of the most important components of the health care system, which provides medical diagnostic assistance to patients in assessing health status, diagnosis of diseases, monitoring of the results of treatment, further prediction of the course of the disease and quality of life that has a national importance in preserving and improving  the health of  the population.

Article deals with topical issues of quality management of medical services and their implementation in practical activity. For quality of research results, serious problems are created by a lot of objective and subjective factors. To eliminate the problem factors, the course was aimed at developing national standards in the field of laboratory medicine, using international experience that regulate the requirements for the organization of clinical diagnostic laboratories and laboratory analysis facilities. The acute problem of laboratory research is to ensure the accuracy of the results.

The analysis methods of quality control on production 3D- printer for selective laser sintering technology of special products via the sizes of which we can estimate the geometric parameters and via an additional control system we can high up their quality in real time. Increasing demands for precision measurement raises new problems of optimization of mathematical models of measuring  transformations, and adequate processing of experimental data.
