Numerische Methoden der Ventilationsauslegung von Hydrogeneratoren werden kontinuierlich verbessert. Die vorliegende Arbeit zeigt eine qualitative Momentaufnahme des Entwicklungsstatus und einen Ausblick der Weiterentwicklung in Andritz Hydro durch eine komprimierte Darstellung Anwender-relevanter und kritischer Eigenschaften der Methoden. Pumpspeichergeneratoren (meist Grenzleistungs-Hydrogene...

The Roman imperial monarchy is generally studied from the vantage point of ancient Roman history: the “Roman emperor” is viewed and analyzed as an element of the Roman world. This conventional approach fails to place this institution in a broader comparative context, that of monarchical rulers across world history. Systematic comparison opens up new perspectives and is indispensable in identify...

A Roman dominating function (RDF) on a graph G = (V,E) is a function f : V → {0, 1, 2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2. The weight of f is w(f) = ∑ v∈V f(v). The Roman domination number is the minimum weight of an RDF in G. It is known that for every graph G, the Roman domination number of G is bounded above...

A Roman dominating function (RDF) on a graph G is a function f : V (G) → {0, 1, 2} satisfying the condition that every vertex v for which f(v) = 0, is adjacent to at least one vertex u for which f(u) = 2. The weight of a Roman dominating function f is the value f(V (G)) = ∑ v∈V (G) f(v). The Roman domination number of G, denoted by γR(G), is the minimum weight of an RDF on G. For a given graph,...

Résumé Dans cet article, nous dressons un bilan du travail effectué sur les ressources du grec moderne concernant le Lexique-Grammaire des verbes. Nous détaillons les propriétés définitoires de chaque table, ainsi que l'ensemble des changements effectués sur les intitulés de propriétés afin de les rendre cohérents. Grâce à l'élaboration de la table des classes, regroupant l'ensemble des proprié...

A Roman dominating function on a graph G is a function f : V (G) → {0, 1, 2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2. The weight of a Roman dominating function is the value f(V (G)) = ∑ u∈V (G) f(u). The Roman domination number of G, γR(G), is the minimum weight of a Roman dominating function on G. In this paper, we...

Im Rahmen dieses Artikels wird die während der Grabungskampagnen 2012-2013 gefundene spätantike Sigillata aus Adramytteion (moderne Siedlung Ören/Balıkesir) untersucht. Das vorliegende Material stammt unterschiedlichen Bereichen Stadt und setzt sich zusammen Formen African Red Slip (ARS), Late Roman C (LRC) Light Coloured Ware (LRLCW), anhand ihrer typologischen Merkmalen in das 3. bis 7. Jh. n...
