We live in a very complex world where we face complex phenomena such as social norms and new technologies. To deal with such phenomena, social scientists often use reductionism approach where they reduce them to some lower-lever variables and model the relationships among them through a scheme of equations. This approach that is called equation based modeling (EBM) has some basic weaknesses in ...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
Soltanabad metamorphic complex cropped out in the ophiolitic range of NE Sabzevar. There is a distinct gneissic body exposed in this complex which is associated with metabasite, serpentinite and adakitic intrusions. Quartz, albite, epidote, amphibole, garnet and chlorite are the rock forming minerals of gneissic samples. Based on abundances of light and dark minerals, different types of felsic,...
مهندسان در طراحی های بزرگ و پیچیده، قبل از ساخت نمونه فیزیکی و برآورد هزینه و زمان ساخت آن احتیاج به شبیه سازی کامپیوتری سخت افزار دارند. از طرفی سرعت شبیه سازهای متداول برای حجم بزرگ مدار بسیار کند می شود و این به دلیل محاسبات زیادی است که برای بدست آوردن اطلاعات ریز زمانی مدار انجام می شود. اما در بسیاری از موارد یک طراح احتیاج به دیدن درستی عملکرد طرح خود دارد و نه اطلاعات ریز زمانی آن. در ا...
Abstract It is well known that sulfonamide derivatives, through exchange of different functional groups without modification the –S(O) 2 N(H)– function, can exhibit a wide variety pharmacological activities. In addition, some metal complexes these ligands have been prepared to promote rapid healing burns in humans and animals, for example, complex Zn( ii ) sulfadiazine. Their effectiveness does...
the complex-step derivative approximation is applied to compute numerical derivatives. in this study, we propose a new formula of fractional complex-step method utilizing jumarie definition. based on this method, we illustrated an approximate analytic solution for the fractional cauchy-euler equations. application in image denoising is imposed by introducing a new fractional mask depending on s...
The objective of the current paper is to present an intelligent system for complex process monitoring, based on artificial intelligence technologies. This system aims to realize with success all the complex process monitoring tasks that are: detection, diagnosis, identification and reconfiguration. For this purpose, the development of a multi-agent system that combines multiple intelligences su...
an iodide ion-selective pvc membrane sensor based on copper (π)-bis-nphenilsalicyldenaminatocomplex as a novel sensing material is successfully developed. theelectrode showed a good selectivity for iodide ion with respect to common inorganic anions. thesensor exhibited a good linear response with slope of _58.6 ± 0.4 mv per decade over theconcentration range of 5.0 × 10-6 to 1.0 × 10-1 mol l-1,...
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...
