Myhill-Nerode Theorem is regarded as a basic theorem in the theories of languages and automata and is used to prove the equivalence between automata and their languages. The significance of this theorem has stimulated researchers to develop that on different automata thus leading to optimizing computational models. In this article, we aim at developing the concept of congruence in general fuzzy...

if the target of foreign language teaching is to use the language, communicative language teaching (clt) seems to be an ideal teaching model. the goal of teaching with this method is to use the language as a medium of communication (adi, 2012).the application of the communicative approach in teaching english as a foreign language, however, is associated with some problems that can cause the met...

language like other inventions was originated to serve human needs in different civilization. different language was created later. contextually the importance of translation from one language to another is not only to understand words; as the words are not the elements of translation. importance and base of translation lies in context to understand it. after getting the content, one should d...

objectives: profound hearing loss encounters children with delay in speech and language. as it is known language acquisition in young deaf children is a lengthy process, but cochlear implanted children have better spoken language skills than if they had not received the device. according to the importance of cochlear implant in deaf child's language development, this study evaluates the ef...
