The author presents an algorithm of slewing motion control in telescopic crane mounted on a chassis of a truck (mobile crane). The control algorithm allows the crane to carry load to a selected point, and it also ensures suppression of swing at the endpoint of the motion. The attention was focussed mainly on the control of slewing motion of the crane body in the case of non-planar distribution of forces acting on the load during its motion.

The purpose of this study is to solve the efficiency and reliability problems of upstream water intake structures for energy and irrigation systems in the region of the Republic of Azerbaijan. Among the methods used in the study, experimental, analytical, and modelling methods should be distinguished. During the study, analyses and field investigations of main structures, and energy and irrigation systems in the foothills were conducted to identify the reasons for the low efficiency and reliability of existing old water intake structures and reduce their negative impact on the environment. The results of the study showed that many water intake structures built on small rivers are not only in poor working condition but also do not meet modern environmental requirements. Many of these structures were built more than thirty years ago and have not been modernized or reconstructed in accordance with new technologies and requirements. As a result of the study, recommendations were prepared for the design of new water intake structures that meet all modern environmental requirements and guarantee the more efficient use of water resources. These new facilities will also help to reduce water losses during the overflow process, which will make the use of water more cost-effective. Additionally, one of the main outcomes is the developed useful model, which pertains to the field of hydroengineering construction for water intake from mountain and foothill rivers, serving as an additional barrier to reduce the influx of large sediment into the reservoir.

The coming into force of the regulations of the ISPS code was cause for significant hope. The new safety system based on the ISPS code created an international framework for cooperation aimed at detecting threats and undertaking appropriate preventative measures within the scope of protecting vessels, ports, and port facilities against potential terrorist attacks. Additionally, the ISPS code should have ensured the effective and rapid flow of all information regarding threats. During the implementation of the new safety system, many legal and practical problems arose which rendered the effectiveness of the system highly doubtful. The continuing inflation of regulations and the bureaucracy of the entire system will lead to the conclusion that the regulations of the ISPS code are de facto a system of 'paper safety' the implementation and maintenance of which are costly and incommensurable to the benefits of applying the new safety standards.

The purpose of the work was to predict the selected product parameters of the dry separation process using a pneumatic sorter. From the perspective of application of coal for energy purposes, determination of process parameters of the output as: ash content, moisture content, sulfur content, calorific value is essential. Prediction was carried out using chosen machine learning algorithms that proved to be effective in forecasting output of various technological processes in which the relationships between process parameters are non-linear. The source of data used in the work were experiments of dry separation of coal samples. Multiple linear regression was used as the baseline predictive technique. The results showed that in the case of predicting moisture and sulfur content this technique was sufficient. The more complex machine learning algorithms like support vector machine (SVM) and multilayer perceptron neural network (MPL) were used and analyzed in the case of ash content and calorific value. In addition, k-means clustering technique was applied. The role of cluster analysis was to obtain additional information about coal samples used as feed material. The combination of techniques such as multilayer perceptron neural network (MPL) or support vector machine (SVM) with k-means allowed for the development of a hybrid algorithm. This approach has significantly increased the effectiveness of the predictive models and proved to be a useful tool in the modeling of the coal enrichment process.

The aim of the article is to show the inculturation of faith and the popular religiosity as the context in which Pope Francis’ Marian spirituality and Mariology have been shaped. Inculturation of faith began in South America with Mary’s apparition in Guadalupe in 1531, however, the theological reflection on the importance of evangelization of culture and popular piety developed in South America only after the Second Vatican Council. The milestones in its development are two Conferences of CELAM: in Puebla in 1979 and in Aparecida in 2007. Moreover, the emergence of Argentinean theology of the people in the 1970s played also an important role in its development. Pope Francis, in his programmatic apostolic exhortation Evangelii gaudium emphasized Mary’s place in popular piety and her role in preaching the Gospel.

The article raised issues related to the design and execution of low-energy objects in Polish conditions. Based on the designed single-family house, adapted to the requirements of the National Fund for Environmental Protection and Water Management ("NF40" standard), the tools to assist investment decisions by investors were shown. An economic analysis and a multi-criteria analysis were performed using AHP method which had provided an answer to the question whether it is worthwhile to bear higher investment costs in order to adjust to the standards of energy-efficient buildings that fulfil a minimal energy consumption's requirements contained in Polish law. In addition, the variant of object that had optimal characteristics due to the different preferences of investors was indicated. This paper includes analysis and observations on the attempts to unify that part of the building sector, which so far is considered to be personalized, and objects in accordance with the corresponding idea are designed as "custom-made".

This study presents the figure of Professor Ludwik Bandura as a fighter, teacher, scientist of special sensibility and a model of humanity. Then there is a discussion of L. Bandura's (1947) research on the harm done to children by war and the obligations of the “socialized school” towards children of war that result from these experiences.
