Abstract. Boolean grammars are an extension of context-free grammars, in which all propositional connectives are allowed. In this paper, the notion of ambiguity in Boolean grammars...
Abstract. Cellular Automata can be considered discrete dynamical systems and at the same time a model of parallel computation. In this paper we investigate the connections between ...
In this paper, we study the benefits of advertising wavelength availability in a distributed lightpath establishment environment by extensive simulations. Various cases with diffe...
We prove that the out-distance sequence {f+ (k)} of a vertex-transitive digraph of finite or infinite degree satisfies f+ (k + 1) f+ (k)2 for k 1, where f+ (k) denotes the numbe...
Stackable ROADMs (S-ROADMs) have been proposed for use in regional IP-over-CWDM networks. The S-ROADM can be constructed by connecting modules with different wavelengths required i...
