Creating Algorithmic Symbols to Enhance Learning English Grammar
This paper introduces a set of English grammar symbols that the author has developed to enhance students’ understanding and consequently, application of the English grammar rules. A pretest-posttest control-group design was carried out in which the samples were students in two girls’ senior high schools (N=135, P ≤ 0.05) divided into two groups: the Treatment which received gramm...
متن کاملManifestation of Alchemy Symbols in Corresponding with Islamic Mysticism and Art

متن کاملContext - Free Grammar - Part 1 Patricia
The notation and terminology used here have been introduced in the following papers: [9], [7], [1], [8], [10], [11], [4], [2], [6], [5], and [3]. We consider context-free grammars which are systems 〈symbols, a initial symbol, rules〉, where the symbols constitute a non-empty set, the initial symbol is an element of the symbols, and the rules constitute a relation between the symbols and (the sym...
متن کاملP Systems with One Membrane and Symport/Antiport Rules of Five Symbols Are Computationally Complete
We consider P systems with only one membrane using symport/antiport rules and prove that any recursively enumerable set of k-dimensional vectors of natural numbers can be generated (accepted) by using at most k + 4 symbols; hence, any recur-sively enumerable set of natural numbers can be generated (accepted) by using at most five symbols.
متن کاملCooperating distributed context-free hexagonal array grammar systems with permitting contexts
In this paper we associate permitting symbols with rules of Grammars in the components of cooperating distributed context-free hexagonal array grammar systems as a control mechanism and investigating the generative power of the resulting systems in the terminal mode. This feature of associating permitting symbols with rules when extended to patterns in the form of connected arrays also requires...
