One way out of this situation is to analyse systems in their normal operation when no adverse event occurs. It can be done, inter alia, with the Functional Resonance Analysis Method. An important research problem in this context is how to describe the variability of system functions. In this article, we propose an original method, based on the number of hazard sources present in a given analysis domain and apply it to a real pedestrian crossing. The obtained results indicate that the quantitative coincidence measures proposed by us are a convenient way to capture ‘functional vibrations’ in real socio-technical systems. This allows the prediction of undesired states of such systems based on their normal operation.","PeriodicalId":43740,"journal":{"name":"Scientific Journal of Silesian University of Technology-Series Transport","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45045356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Austenitic steel has high resistance to atmospheric corrosion. The austenitic steel is treated as a good weldable material, although cracks are possible. This paper analyses the influence of various MIG welding parameters on the creation of correct joints used in the stainless steel structures of mobile platforms elements, as an example of welding structures, in various means of transport. Various tests verifying the mechanical properties of MIG welds, including non-destructive tests, tensile strength and hardness tests, were carried out. This article aims to show how important and complex the task is to select the correct welding parameters for elements of means of transport made of austenitic steel on the example of elements of mobile platforms.","PeriodicalId":43740,"journal":{"name":"Scientific Journal of Silesian University of Technology-Series Transport","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47204117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has spread in the areas of design, modernization and reconstruction of energy-efficient buildings and structures, design and construction of elements of industrial infrastructure, and technological production processes. Introduction of such projects is a priority for enterprises and companies of various types of economic activity. Thus, the leading industries develop strategies to improve environmental safety and energy efficiency - shipping is no exception, where the process of improving energy efficiency is carried out through various mechanisms, ultimately leading to a reduction in emissions of pollutants, but having a negative impact on the performance of the commercial operation of the ship. Problems of ensuring energy efficiency along with increasing requirements for environmental safety of transport and strengthening the responsibility of shipowners become the focus of research of modern theory and practice of operation of means of maritime transport. The issues of improvement of universal principles of energy efficiency within individual shipping companies and development of tools for economic analysis of energy efficiency of own fleet, search for new ways of forming professional competencies of ship crew members in the field of energy efficiency continue to be topical as well.","PeriodicalId":43740,"journal":{"name":"Scientific Journal of Silesian University of Technology-Series Transport","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41444660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High maternal deaths observed in some regions of Turkey are related to inequities in reaching health services (low transport facilities). To prevent maternal mortality, pregnant women should have access to health services for professional care before, during, and after childbirth. In Turkey, most maternal deaths are related to socio-economic factors, equity issues, health services and transportation facilities. Especially, transportation facilities to health centers play an important role in preventing maternal deaths. Thus, to prevent the negative effect of the winter season and adverse transportation facilities on maternal mortality, the Turkey Ministry of Health (MoH), aiming to reduce the maternal mortality ratio (MMR) in rural areas, initiated the “Guest Motherhood Project (GMP)” to cover all of its urban and rural areas. In this project, health services for pregnant women in risky regions were restructured. In the scope of the project, access problems to health centers were eliminated and rapid access to rural areas and challenging territories of Turkey were provided. Current maternal mortality statistics show that GMP is yielding good results and high quality delivery services at all health centers in every region of the country despite the regional disparities.","PeriodicalId":43740,"journal":{"name":"Scientific Journal of Silesian University of Technology-Series Transport","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67724646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, there was a significant reduction of 2 other emission elements, namely the unburned hydrocarbons decreased by 61%, and the amount of particulate matter was reduced by 18%. Measured engine power increased by 1.2% using the modified oil filter, which proves the success of this filter.

Presently, work is being conducted globally to solve related problems. At the moment, it is not yet possible to create a single procedure that would enable the construction of a properly functioning diagnostic system, regardless of the selected object to be diagnosed. Hence, there is a need to conduct further research into the possibility of using already developed methods, as well as their modification to other diagnostic cases. This article presents the results of research related to the use of the Bayes classifier for diagnosing the technical condition of passenger car engine components. Damage to the exhaust valve of a spark ignition engine was diagnosed. The source of information on the technical condition was vibration signals recorded at various measuring points and under different operating conditions of the car. To describe the nature of changes in the vibration signals, the entropy measures were determined for the decomposed signal using the discrete wavelet transform is proposed.","PeriodicalId":43740,"journal":{"name":"Scientific Journal of Silesian University of Technology-Series Transport","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47855193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
