Unconditional Transfer in Regulated Rewriting Unconditional Transfer in Regulated Rewriting
In this paper, we investigate the concept of unconditional transfer within various forms of regulated grammars like programmed grammars, matrix grammars, grammars with regular control, grammars controlled by bicoloured digraphs, periodically time-variant grammars and variants thereof, especially regarding their descriptive capacity both as language generating and as language accepting devices. ...
متن کاملOn Unconditional Transfer
In this paper, we investigate the concept of unconditional transfer within various forms of regulated grammars like programmed grammars, matrix grammars, grammars with regular control, grammars controlled by bicoloured digraphs, and periodically time-variant grammars , especially regarding their descriptive capacity. Moreover, we sketch the relations to restricted parallel mechanisms like k-, u...
متن کاملTransforming Conditional Rewrite Systems with Extra Variables into Unconditional Systems
Deterministic conditional rewrite systems are interesting because they permit extra variables on the right-hand sides of the rules. If such a system is quasi-reductive, then it is terminating and has a computable rewrite relation. It will be shown that every deterministic CTRS R can be transformed into an unconditional TRS U(R) such that termination of U(R) implies quasi-reductivity of R. The m...
متن کاملHow Powerful is Unconditional Transfer? - When UT meets AC
We prove that every recursively enumerable language can be generated by a programmed grammar with context-free core rules using unconditional transfer with leftmost derivation of type 3 or type 2. We show that every recursively enumerable tally language can be generated by a programmed grammar with context-free core rules using unconditional transfer or by some k-limited ET0L system, where k 2 ...
متن کاملSimulation of Temperature Distribution in Hot Strip over Transfer Table
Transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. High temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. Using thermal shields on the transfer table is cons...
