[ 1 ] - Moving Mesh Non-standard Finite Difference Method for Non-linear Heat Transfer in a Thin Finite Rod
In this paper, a moving mesh technique and a non-standard finite difference method are combined, and a moving mesh non-standard finite difference (MMNSFD) method is developed to solve an initial boundary value problem involving a quartic nonlinearity that arises in heat transfer with thermal radiation. In this method, the moving spatial grid is obtained by a simple geometric adaptive algorithm ...
[ 2 ] - پلی نومیوگرافی، به وسیله یک روش تکراری جدید
the importance and application of mathematics and its techniques in most of the branches of science is undeniable. one of these applications is polynomiography. Polynomiography is visualization process of finding the roots of a given complex polynomial, and has importance for both the art and science aspects. In this paper, we plan to propose a new iterative technique for polynomiography....
[ 3 ] - High Order Compact Finite Difference Schemes for Solving Bratu-Type Equations
In the present study, high order compact finite difference methods is used to solve one-dimensional Bratu-type equations numerically. The convergence analysis of the methods is discussed and it is shown that the theoretical order of the method is consistent with its numerical rate of convergence. The maximum absolute errors in the solution at grid points are calculated and it is shown that the ...
[ 4 ] - چندجمله ای نگاری؛ تلفیقی از ریاضی و هنر
در این مقاله، قصد داریم چندجمله ای نگاری حاصل از روش های تکراری از خانواده نیوتن را ارائه کنیم. چندجمله ای نگاری فرآیند تجسم ریشه های یک چندجمله ای مختلط است و در بسیاری از زمینه ها همچون آموزش ریاضی، هنرهای تجسمی، صنعت نساجی و قالی بافی کاربرد دارد. طی چند مثال مشاهده خواهیم کرد که با تغییر پارامترها، الگوهای زیبایی حاصل خواهد شد.
