When performing nonlinear system identification few tools exist for the a priori nonlinear model structure selection of the nonlinear system. This paper presents a possible approach as a first step towards selecting a nonlineAtr system model structure, based on using the results of Lyapunov exponents, Poincar~ maps and dimension techniques. The approach is illusUated by applying it to the Chua ...

With the advent of technology, mobile devices are becoming powerful and they are widely used as convenient computing devices. In order to develop high quality application in a short period while overcoming the limitations and challenges in mobile development, strong knowledge and understanding of the design purpose are the key factors in developing welldesigned applications. Good design ensures...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

A methodology is presented for obtaining explicit formulas for the solution of class-P piecewise linear (PL) networks and, inherently, for the linear complementary problem (LCP). The method uses the b c operator, which has been previously defined in the literature to extend the explicit PL model descriptions of Chua. An important consequence of the methodology is that it proves that class-P net...

Some neural network models have been suggested to solve linear and quadratic programming problems. The Kennedy and Chua modell5] is one of those networks. In this paper results about the convergence of the model are obtained. Another related problem is how to choose a parameter value ~ s so that the equilibrium point of the network immediately and properly approximates the original solution. Su...

This paper presents a new chaotic system by resulting from the coupling two different systems such as Rӧssler and Chua system, where x2 dynamic of was coupled with z1 system. Some basic dynamics behaviors were examined for using Matlab program. In this work noticed difference in time series turn led to attractor, attractor changed double scroll single scroll. behavior change bandwidth that mean...
