Conversations processes in the system of automatic communication at sea

100%

Wójcik A.

tom z. 107

217--223

The progressing automation of maritime transport, including the introduction of autonomous and/or unmanned ships, calls for the development of communication principles, particularly conversations currently carried out verbally. The work in this field is intended to improve the safety of maritime transport. This article describes research on automatic communication in the form that will support navigators responsible for ship conduct. The processes of inference and conversation management are described. The developed methods are based on standard marine communication phrases. The presented example conversation between navigators is supported by an automatic communication system. The work herein described aims at the creation of procedures for communication at sea between autonomous ships.

tom Nr 8

25--29

W niniejszym artykule przedstawiono zagadnienia związane z bezpieczną pracą i eksploatacją urządzeń napełnionych gazem SF6. Omówiono wyzwania, przed którymi stoi polska energetyka w erze przemysłu 4.0. Zaprezentowano mechanizm odzysku gazu z eksploatowanego urządzenia oraz proces utylizacji urządzeń elektroenergetycznych i produktów rozpadu SF6. Scharakteryzowano również unormowania prawne dotyczące poruszanej tematyki i normy regulujące gospodarowanie gazem SF6.

Given the whole spectrum of doubts and controversies that arise in discussions about laws affecting historical memory (and their subcategory of memory laws), the question of assessing them in the context of international standards of human rights protection – and in particular the European system of human rights protection – is often overlooked. Thus this article focuses on the implications and conditions for introducing memory laws in light of international human rights standards using selected examples of various types of recently-adopted Polish memory laws as case studies. The authors begin with a brief description of the phenomenon of memory laws and the most signifcant threats that they pose to the protection of international human rights standards. The following sections analyse selected Polish laws affecting historical memory vis-à-vis these standards. The analysis covers non-binding declaratory laws affecting historical memory, and acts that include criminal law sanctions. The article attempts to sketch the circumstances linking laws affecting historical memory with the human rights protection standards, including those entailed both in binding treaties and other instruments of international law.

The article presents a precise method for the orientation process of NiMnGa-based single crystals. For this method, a scanning electron microscope equipped with an EBSD camera and a heating stage allowing temperatures exceeding 873 K was used. The orientation process was carried out in both the high-temperature austenite phase and in the room-temperature martensite phase. The facilities allowed for determining the orientation of a single grain of austenite at elevated temperatures as well as the orientation of particular martensitic variants at room temperature. A practically perfect cubic orientation was obtained in the austenitic case with a deviation of about 1° while the samples oriented in the martensitic phase deviated from the desired orientation by 4.5-5.2°. Additionally, the training process of single crystals was carried out in order to show the influence of the orientation process on twinning stress.
