ity model is used to determine the apparent viscosity. Magnetic field is modelled for a constant current which generates different magnetic flux densities inside the absorber body. The Computational Fluid Dynamics and Finite Elements Analysis solutions are coupled in a two-dimensional axisymmetric d

Generative Capacity,shall compare the families of contextual languages to each other and to the families in the Chomsky hierarchy. The examples in the previous chapter will be useful in this aim, but, in order to find counterexamples we also need conditions for a language to be in a given family. We start by looking fo

Language Theoretic Properties,rative mechanisms. We call them “language theoretic”, but such questions are also of a practical interest. For instance, remember from Chapter 2 the use of operations with languages (and of corresponding closure properties) when trying to prove that a given language (English, for example) does not b

Grammars with Restricted Selection,r all strings in .* (correspondingly, the selectors in the modular presentation can be infinite sets). However, the notion of a “grammar” supposes some sort of finite mechanism which describes the syntax of a language. Restrictions on the general definition of a contextual grammar (on the mapping .
