This paper presents new models for all recursive enumerable languages. These models are based on multigenerative grammar systems that simultaneously generate several strings in a parallel way. The components of these models are context-free grammars, working in a leftmost way. The rewritten nonterminals are determined by a finite set of nonterminal(More)
INTRODUCTION Sudden cardiac arrest is one of the most frequent causes of death in the world. In highly qualified emergency medical service (EMS) systems, including well trained emergency physicians, spontaneous circulation may be restored in up to 53% of patients at least until admission to hospital. Compared with these highly qualified EMS systems, in(More)
This paper presents new models for generating matrix languages. These models are based on multigenerative grammar systems that simultaneously generate several strings in a parallel way. The components of these models are context-free grarrrmars, working in a general way. The rewritten nonterminals are determined by a finite set of nonterminal sequences. The(More)
