Sommario/riassunto |
|
Nach dem Tod August Thyssens versuchte sein Sohn Heinrich Thyssen-Bornemisza, als Unternehmer eigene Wege zu gehen. Die Entwicklung seiner Firmen ist bis heute ein kaum bekannter Teil der Geschichte Thyssens im 20. Jahrhundert. Ab Herbst 1926 verfolgte Heinrich Thyssen-Bornemizsa das Ziel, seinen Erbteil des Thyssen-Konzerns effizient zusammenzufassen. Der von ihm gegründeten Holding gelang es jedoch nicht, ihre Aufgabe als zentrales Lenkungs- und Kontrollorgan zu erfüllen. Die Studie untersucht die Gründe dafür. Zudem beleuchtet sie die Entwicklung und Wettbewerbsposition einzelner Betriebe aus Heinrichs Verbund bis zum Ende seiner Formationsphase 1932 und erklärt, warum sich diese trotz wirtschaftlich schwieriger Rahmenbedingungen erfolgreich am Markt |

Sommario/riassunto |

In graph-based structural pattern recognition, the idea is to transform patterns into graphs and perform the analysis and recognition of patterns in the graph domain - commonly referred to as graph matching. A large number of methods for graph matching have been proposed. Graph edit distance, for instance, defines the dissimilarity of two graphs by the amount of distortion that is needed to transform one graph into the other and is considered one of the most flexible methods for error-tolerant graph matching.This book focuses on graph kernel functions that are highly tolerant towards structural |
