PL Zaprojektowano algorytm kontroli błędu zegara stosowanego w nawigacji w przestrzeni kosmicznej przy pomocy pulsara X (promieniowania rentgenowskiego) i pojedynczego detektora. W algorytmie błąd zegara pokładowego rozpatrzono jako składnik równań stanu statku kosmicznego, następnie przeprowadzono jeg[...]
EN The clock error control algorithm for X-ray pulsar-based navigation using a single detector is proposed. In this algorithm, the clock error on-board is also considered as a component of the explorer’s state, and then it can be estimated during the navigation process. Moreover, an improved measuremen[...]

PL W artykule zaproponowano wykorzystanie hybrydowego połączenia optymalizacji rojem cząstek i algorytmu genetycznego w optymalizacji procesu montażu/łączenia części. Metoda bazuje na funkcji użyteczności wynikającej z propagacji błędu złożenia. Efekty działania zaprezentowano na przykładzie składania [...]
EN The assembly dimensional quality can be improved by optimizing the assembly operations between parts. Firstly, as there is large quantity of geometric feasible assembly sequences for the auto-body, the multi-attribute directed liaison graph is applied to describe the precedence relationships and ass[...]

EN Two entropy principles that are commonly used are: (i) the Clausius-Duhem inequality with the procedure of exploitation due to Coleman-Noll (CD-CN), and (ii) the entropy principle of Mueller-Liu (ML). CD-CN makes a priori postulates about the entropy flux and entropy supply and assumes external sour[...]

PL Stropy wiszące spotykane są powszechnie w rejonie przodka przy wybieraniu ścianowym, w warunkach dużych obciążeń stropu. Nagłe zarwanie stropu i powstały zawał mogą doprowadzić do wypływu gazu ze zrobów do strefy przodka, wskutek czego stężenia gazu gwałtownie wzrosną, przekraczając bezpieczne warto[...]
EN The occurence of hanging roof commonly arises in the face end of longwall coal mining under hard roof conditions. The sudden break and subsequent caving of a hanging roof could result in the extrusion of gas in the gob to the face, causing gas concentrations to rise sharply and to increase to over a[...]
