Cooperating 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...

متن کاملCooperating Distributed Grammar Systems with Permitting Grammars as Components
This paper studies cooperating distributed grammar systems working in the terminal derivation mode where the components are variants of permitting grammars. It proves that although the family of permitting languages is strictly included in the family of random context languages, the families of random context languages and languages generated by permitting cooperating distributed grammar system...

wind farm impact on generation adequacy in power systems
در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...
