this paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and petri nets. in the beginning, programmable logic controllers were widely designed by ladder logic diagrams. when complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. thus, petri nets as a high l...

This paper will examine Ibn Sina’s theory of the Conditional Syllogism from a purely logical point of view, and will lay bare the principles he adopted for founding his theory, and the reason why the newly introduced part of his logic remained undeveloped and eventually was removed from the texts of logic in the later Islamic tradition.

امروزه با توجه به افزایش روزافزون نیاز آبی، کنترل و استفاده بهینه از آبهای سطحی، از پارامترهای مهم و ضروری می باشد.برای نیل به این هدف، نیاز به ساخت سدهای متعدد و پیایی به منظور استفاده بهینه از آب موجود، بیشتر از گذشته احساس می شود. بنابراین باید با استفاده از روشها و مدلهای مختلف موجود، هزینه ساخت این گونه سدها و سازه های وابسته از جمله هزینه سیستم انحراف را کاهش داد. در گذشته به دلیل وجود تع...
