  • The use of vector analysis to create algorithms of intelligent software supporting microscopic qualitative examination of welds
    The article discusses the methods of computer image analysis known from aerial sights (hidden by military scientists of the last century in psychology and research on linguistic image description), image analysis from a welding robot camera, and computer aided microscopic research. In the article, to create algorithms for recognizing microscopic structures of steel, a method known from linguistics was used to convert metaphorical statements into vectors, i.e. into a mathematical notation. In the vector analysis, inherited and learned types of abilities were taken into account. The result of the analysis, which is identical for the algorithms corresponding to the 3 types of ability, gives the certainty of uniqueness. In other cases, additional knowledge on the technology of formation of the microscopic structures under study is needed. Introduction The assessment of the effectiveness of microscopic examinations shows a large dispersion of the results of examinations involving the use of image analysis, i.e. radiographic examinations and microscopic examinations. This is due to the fact that a person "sees" more with the brain (biological computer) than with the use of optics, and the test result depends on the experience and skills of the laboratory technician. Once the director of Huta im Lenin in Krakow was asked why they only employ metal scientists in the Central Laboratory. He replied that most of the engineers in the steelworks were metallurgists who, after the failure, submitted samples for metallographic tests and the test results did not confirm the actual causes of the damage, and that was why it was decided to leave only a few metal experts to represent the steelworks in courts, because they were not useful in production. Therefore, in order to improve the effectiveness of these studies, there is a need for computer-aided microscopic studies and the development of laboratory training methods resembling the training of astronauts and pilots (biological computer programming).
  • Legal aspects of the construction and installation of lifts
    The legal and normative acts discussed in the article concern the scope of responsibility for lift installations in Poland in relation to European law. The most important acts, regulations and standards related to the design, construction of these installations and the operation of elevators in buildings were discussed. The current approach to the implementation of such installations in vertical mining excavations in the aspect of mining and geological law is also described. One of the directions to be followed in the research work in order to reduce the energy consumption of lifting devices was indicated, and the need to amend legal acts concerning the installation of these devices in mining shafts was discussed. Introduction The technical development at the turn of the 20th and 21st centuries was extremely fast and required the rulers to create a legal system sufficiently quickly that would enable the implementation of new technical solutions in the society, while ensuring the safety of users. One of the branches of technology related to the construction and operation of machines is crane technology. The legal system currently in force in Poland regarding this aspect is based on Directive 2014/33 / EU of the European Parliament and of the Council of February 26, 2014 on the harmonization of the legislation of the Member States relating to lifts and safety components for lifts (Journal of Laws UE L 96 of March 29, 2014, p. 251). The legal act that implements this directive in Poland is the Regulation of the Minister of Development of June 3, 2016 on the requirements for lifts and safety components for lifts. Together with the content of the European Union Directive on passenger lifts, standards harmonized with this directive have also been developed and adopted. Harmonized standards are also part of the EU law, but their application is voluntary.
