به کارگیری دینامیک های جاذب نقطه ای به عنوان حافظه های انجمنی به دهه ی هشتاد میلادی و معرفی شبکه ی هاپفیلد باز می گردد بازیابی حافظه در این سیستم ها با استفاده از شبکه های بازگشتی صورت می گیرد. در کنار این دینامیک های جاذب وجود فعالیت ماندگار در سلول های مغز به همراه ساختارهای بازگشتی در نواحی قشری مغز، ما را به سمت تکامل دینامیک های جدیدتری به نام شبکه های عصبی یا جاذب های پیوسته سوق می دهد. د...

background: nowadays the eutrophication of water bodies is enhanced due to discharge of effluents and runoffs. therefore, there is a demand for the management of natural and artificial lakes to prevent or postpone this problem. lakes eutrophication is a complex process. therefore computerized models are very important tools to describe this process. although there are several models for this, b...

this paper aims to study a generalized double sinh-gordon equation, which appears in several physical phenomena such as integrable quantum field theory, kink dynamics and fluid dynamics. lie symmetry analysis together with the simplest equation method is used to obtain exact solutions for this equation. moreover, we derive conservation laws for the equation by using two different approaches, na...

We investigate some properties of approximately quasi inner generalized dynamics and quasi approximately inner generalized derivations on modules. In particular, we prove that if A is a C*-algebra, is the generator of a generalized dynamics on an A-bimodule M satisfying and there exist two sequences of self adjoint elements in A such that for all in a core for , , then is approx...
