The synergistic interaction between teammates in association football has properties that can be captured by Social Network Analysis (SNA). The analysis of networks formed by team players passing a ball in a match shows that team success is correlated with high network density and clustering coefficient, as well as with reduced network centralization. However, oversimplification needs to be avo...

In the field of sports games the analysis of the game structure as well as the analysis of the opponent team is of major interest for the training process in order to optimize tactical skills. Based on methodological problems of present game analysis some recent approaches apply artificial neural networks to examine the game structure. With the intention to analyze types of tactical structures ...

Adaptation in multimedia systems is usually restricted to defensive, reactive media adaptation (often called stream-level adaptation). We argue that offensive, proactive, system-level adaptation deserves not less attention. If a distributed multimedia system cares for overall, end-to-end quality of service then it should provide a meaningful combination of both. We introduce an adaptive multime...

Let G = (V (G), E(G)) be a graph, and let k ≥ 1 be an integer. A set S ⊆ V (G) is called a global offensive k-alliance if |N(v) ∩ S| ≥ |N(v)−S|+k for every v ∈ V (G)−S, where N(v) is the neighborhood of v. The global offensive k-alliance number γ o (G) is the minimum cardinality of a global offensive k-alliance in G. We present different bounds on γ o (G) in terms of order, maximum degree, inde...

the purpose of this study was to show types and extent of offensive behaviors at soccer stadiums and to test the relationship between personal factors, spectators, verbal behavior of stadium executives and staff, sport media biases, modeling from famous team spectators, refereeing the matches, and win-oriented spectators with offensive behavior of the spectators. a total of 727 researcher-made ...
