    Computer visual inspection of pear quality
    (Видавництво Львівської політехніки, 2023-02-28) Ilchuk, Mykhailo; Stadnyk, Andrii; Lviv Polytechnic National University
    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%. Therefore, the results obtained in this work make it possible to automate the process of visual inspection with the prospect of increasing the speed and quality of product sales for the consumer.

    Material testing and results estimation by safety indexes
    (Видавництво Львівської політехніки, 2021-02-23) Mykyichuk, Mykola; Rudyk, Yuriy; Lviv Polytechnic National University; Lviv State University of Life Safety
    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. These techniques' effective thermal condition is in an environment of uncertainty and has no limited resources was established. Concepts and principles for establishing validity, and frameworks and methods for validating test methods and their results are important elements of safety systems. The article considers the safety of the technical component of a complex organizational and technical system with the study of the functional relationship between the safety elements parameters: temperature, time, fire retardant – by hydrogen participation.

    Risk management in the clinic – diagnostic laboratories
    (Видавництво Львівської політехніки, 2020-02-24) Sydorko, Ihor; Baitsar, Roman; SE “Lviv Scientific and Production Center for Standardization, Metrology, and Certification”; Lviv Polytechnic National University
    Adopting socially responsible management practices of the organization promotes greater awareness in decisionmaking, 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. The concept of “risk” today has a fairly broad meaning and is used in completely different contexts. Synonyms of risk can be such concepts as “danger”, “threat”, “trouble”, etc. However, in many definitions of risk in the scientific literature, this term is used in a special sense, where risk is associated primarily with the concept of uncertainty. Therefore, the risk is understood as uncertainty, which can result in one or another adverse event. Clinical risks – risks that arise directly from the provision of medical care. These include clinical errors and negligence, infections in medical care, and non-consent. The principles of risk management and the need to use them are effectively applied in many areas of economic activity and public administration, including health care, as well as institutions that provide regulatory activities in these areas, including clinical diagnostic laboratories. Today, prevention as management of patient quality of health has become a dominant part of medicine, where laboratory diagnostics, which can detect the risks of many diseases, is not the least important. The presence in the health care system of only certain fragments of activity risk necessitates the formation of an overwhelming majority of an effective integrated risk management system, which must comply with certain requirements and principles: determining the characteristics of the system; optimization of the risk management model of medical structures; substantiation of prerequisites for the introduction of a comprehensive medical risk management system and evaluation of the effectiveness of its operation.
