  In the paper we introduce and study a new problem of finding a minimum global edge alliance in a graph which is related to the global defensive alliance (Haynes et al., 2013; Hedetniemi, 2004) and the global defensive set (Lewoń et al., 2016). We proved the NP-completeness of the global edge alliance problem for subcubic graphs and we constructed polynomial time algorithms for trees. We found the exact values of the size of the...

  In the talk the authors present some tight upper bounds on global edge alliance number and global complete alliance number of trees. Moreover, we present our NP-completeness results from [8] for global edge alliances and global complete alliances on subcubic bipartite graphs without pendant vertices. We discuss also polynomial time exact algorithms for finding the minimum global edge alliance on trees [7] and complete alliance...

  For a given graph G, a nonempty subset S contained in V ( G ) is an alliance iff for each vertex v ∈ S there are at least as many vertices from the closed neighbourhood of v in S as in V ( G ) − S. An alliance is global if it is also a dominating set of G. The alliance partition number of G was defined in Hedetniemi et al. (2004) to be the maximum number of sets in a partition of V ( G ) such that each set is an alliance. Similarly,...

  Opisano zagadnienia superpozycji naprężeń dynamicznych od zginania ogólnego i strefowego, we wzdłużnych wiązarach kadłuba statku. Krytycznie skomentowano wymagania przepisów klasyfikacji i budowy statków, dotyczące oceny wytrzymałości tych elementów konstrukcji. Przedstawiono sposób wykonywania prognozy długoterminowej naprężeń w tych elementach i zaproponowano sposób sumowania charakterystycznych wartości naprężeń od zginania...
