The predominant goal of the research presented in this paper is the design of a manipulator for a conveyor of bulk materials based on the given requirements. This issue is an emerging topical one mainly for the reasons of increasing efficiency and speed, as well as the safety of maintenance of machines and equipment. Especially, another essential aspect is the reduction of the physical strain on operators during service operations on the conveyor of bulk materials. The introductory part of this paper attends to the materials used for the production of steel structures, their technological processing, as well as different types of joining of their components. The practical part was set out to ascertain the mass and position of the center of gravity of the load itself – the conveyor. From the perspective of acting, it loads the entire proposed structure, although in different operating modes.

Research presented in this article was undertaken to determine how representatives of authorities and residents of communes perceive airports in the context of the impact of these airports on the socio-economic situation in the communes. The goal was achieved using: analysis of documentation of communes, analysis of data on the functioning of airports, and a diagnostic survey using the interview technique and survey technique. The research was carried out on representatives of 5 communes located in Poland. To analyse the collected material and present the results, Statistica v.13.3, R v.4.0.0 and RStudio editor software were used. Results of this research proved that airports play a pivotal role in stimulating the development of the region. They influence the quality of life in the commune by contributing to the creation of jobs, attracting investors, and generating income for the municipal budget through taxes paid.

Traffic surveillance provides crucial data for the operation of intelligent transportation systems. The growing number of cameras in the transport system poses a problem for the efficient processing of surveillance data. Processing of video data for extracting traffic parameters is usually done using image processing methods and requires substantial processing resources. An alternative way is to transform the video stream and map the traffic parameters using the obtained transform coefficients. Spatiotemporal wavelet transform of the video stream contents, using filter banks, is proposed for mapping traffic parameters. Performed tests prove good resilience to illumination changes of road scenes. Mapping errors are smaller than in the case of the commonly used video detectors at sites on multilane roads with low to moderate traffic load.

Pipeline transport is used worldwide in many sectors of the economy. Its main advantages are continuity of transport, large transportation volumes, small energy consumption, safety, reliability and high environmental benefits. However, the safety problems of pipes attract much interest in science and industry. This paper deals with a cracked pipe with a static scheme of a simply supported beam. It rests along its entire length on a Pasternak elastic foundation. The flowing fluid is considered non-compressible and heavy. The Galerkin method is employed to approach the problem numerically. Conclusions are drawn based on the influence of the crack and the parameters of the Pasternak elastic foundation on the critical flow velocity of the fluid.

For many years in many Western Europe countries, cycling has been associated with not only recreation and tourism but has equally gained an important function as a means of transport used in everyday commuting to work, study and entertainment. The bicycle appears to be a very good alternative to motor vehicles that produce exhaust fumes and create congestion on road transport networks. Not only is the bicycle environmentally friendly and takes up little space in road transport networks, but also, the time of bicycle travel is often competitive in relation to travel made by private car or public transport. This article presents the characteristics of the bicycle infrastructure and services offered in selected cities in the world and Poland, as well as the issues of bicycle counters as sources of data on bicycle traffic volume, along with an exemplary analysis of this type of data.

To effectively transport materials through different means of transport, it is essential to have an optimized warehouse logistics first. Thanks to the Industry 4.0 platform, there are several ways to accomplish the delivery of materials from a warehouse through transport by road, rail or air. This paper deals with a primary warehouse problem, which is the fast and accurate search and selection of required items in the stock. For this issue, the use of smart glass technology and its implementation in the logistic processes of warehouses could help. In a particular way, an IRS (Integrated Rescue System) warehouse was selected as an example. The augmented reality (AR) type of glasses was selected. The introductory part of this paper deals with the current situation in the warehouse and logistic processes, where the problem of lack of qualified staff and material supply is prevalent, particularly during different crisis situations, such as pandemics or high employee turnovers. The use of smart glasses is one of the many possible problem-solving variants in this field. Further, a basic description of smart glasses, possible uses and sorting are presented in this paper. For the experiment, it was necessary to choose several different commercially available models of smart glasses. An evaluation was provided by the Simple comparative method, Saaty's method and Linear partial utility function method and the best options were identified. Also, there is an example of smart glasses application for picking a particular component in an IRS warehouse in the last part of this paper.

Widespread use of innovative technologies in all spheres of life has brought the maritime transport industry, in particular, the process of ship navigation, to a completely new qualitative level. Various navigation systems recently introduced and used only as additional devices have gradually become an obligatory element of shipboard equipment and navigation complexes of modern vessels, extending their functionality and capabilities. The human factor influence caused by automation of ship operation processes becomes a separate challenge. Risks to shipping safety and consequences of breach of safety standards for crew, vessel and cargo are far from being a full list of the problems to be solved. This paper offers an overview of general issues of ensuring the level of safety of shipping, by examining the concept of "vessel safety", considering its individual sides, features, as well as constituent aspects of the concept, systematization of the vessel safety structure to develop solutions toward improving the integral safety and optimization of decision-making in emergencies. Achievement of the general purpose of shipping safety thus means the realization of ways of reducing the influence of the human factor on several accidents and an estimation of the degree of influence of a set of factors on a ship during operation.

Today, being a member of the Fire-Rescue Department (FRD) is challenging as it is a risky and professionally demanding job, which often requires an individual schedule both in terms of physical condition and psychological knowledge as well as safety and health protection at work. Apart from the standard services provided by the FRD and the integrated rescue system, their members also participated in hundreds of interventions during emergencies and crisis situations to mitigate the impacts of the pandemic on society.

In some areas of transportation systems, reduction of risk using typical safety engineering tools can be difficult due to the relatively small number of events that can be analysed to draw conclusions for the future. 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.
