A global offensive alliance in a graph G = (V,E) is a subset S of V such that for every vertex v not in S at least half of the vertices in the closed neighborhood of v are in S. We give an upper bound on the global offensive alliance number of a graph in terms of its degree sequence. We also study global offensive alliances of random graphs.

Large-scale competitive P2P systems are threatened by the noncooperation problem, where peers do not forward queries to potential competitors. While non-cooperation is not a problem in current P2P free file-sharing systems, it is likely to be a problem in such P2P systems as pay-per-transaction file-sharing systems, P2P auctions, and P2P service discovery systems, where peers are in competition...

An increasing number of freely accessible adult content websites arose recently, displaying a wide variety of different offensive images and videos. Since many users do not want to be confronted with such material, automatic tools to detect and filter these images and videos are needed. Additionally, tools are required to protect children from accessing offensive websites. This thesis presents ...

Possession time in football has been widely discussed in research but few studies have analyzed the importance of the field area in which possession occurs. The objective of this study was to identify the existence of significant differences in the field zone of ball possession between successful and unsuccessful teams and to acknowledge if the match status modulates the possession model. To th...

Aggressive behavior can be studied as either offensive or defensive responses to a stimulus. The studies discussed in this review are focused on the peripubertal development of offensive aggression in male golden hamsters and its responsiveness to repeated social stress. Quantitative and qualitative changes in offensive responses were analyzed during this period. Quantitative changes in offensi...

The field of humanoids robotics is widely recognized as the current challenge for robotics research. Developing humanoids poses fascinating problems in the realization of manipulation capability, which is still one of most complex problem in robotics. The paper, starting from an overview of current activities in the development of humanoid robots, with special focus on manipulation, presents th...

Hamsters repeatedly exposed to cocaine throughout adolescence display highly escalated offensive aggression compared to saline-treated littermates. Recently, we have shown that serotonin neural signaling and development play an important role in adolescent cocaine-induced offensive aggression. This study examined whether the adolescent cocaine-induced aggressive response was modulated by seroto...
