چکیده: 

The Zakharov equation is a nonlinear plasma fluid model, used for ion-acoustic waves in a magnetized plasma. In the present study, Langmuir waves of the dimensionless Zakharov equation are investigated by using the Sardar-subequation method. The obtained solutions lead to a variety of exact solutions in the form of dark, bright, periodic singular,  singular, and combined dark-bright type solutions. These acquired solutions are depicted graphically by the 2D, contour and 3D plots which show the physical behaviour of obtained solutions. All the graphs confirm the validity of the obtained solutions. These types of solutions have a large range of applications in mathematical and applied sciences.

چکیده: 

DNA, or deoxyribonucleic acid, is found in every single cell and is the cell's primary information storage medium. DNA stores all an organism's genetic information, including the instructions it needs to grow, divide, and live. DNA is made up of four different building blocks called nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The genome is sequenced in vitro utilizing encoding strategies such as labelling one bond pair as 0 and the other as 1 to store digital information. In this study, the fractional differential order of double-chain DNA dynamical system was investigated, considering Atangana’s Conformable fractional derivative. The Conformable sub-equation method was applied to the system.  The analysis resulted in some interesting new exact solutions of the model. One-soliton kink solution, multiple-soliton solutions, and periodic-wave solutions are the three broad categories that may be used to describe the results. In order to better understanding the solutions found, we have visually investigated a few of them. Both solitary and anti-solitary waves of the DNA strands are seen, attesting to the nonlinear dynamics of the system. The gathered data might be used to conduct application evaluations and draw further scientific findings.

چکیده: 

In the present article, we utilize the Conformable Double Laplace Transform method (CDLTM) to get the exact solutions of a wide class of Conformable fractional di , er-ential in mathematical physics. The results obtained show that the proposed method is e, cient, reliable and easy to be implemented on related linear problems in applied mathematics and physics. Moreover, the (CDLTM) has a small computational size as compared to other methods.

چکیده: 

در این تحقیق، صفحات ماکرومتخلخل TiO2 دوپه شده با آهن، سنتزشد و به زمینۀ پلی اتربلاک آمید (PEBA) اضافه شد. ریختمان، ساختار شیمیایی، رفتار حرارتی، بلورینگی، استحکام مکانیکی و خواص جداسازی غشاهای تهیه شده، مطالعه شد. نتایج نشان داد که صفحات FeTiO2 با برقراری پیوندهای فیزیکی با زنجیر پلیمری باعث افزایش استحکام مکانیکی آن شد. این صفحات، به وسیلۀ مراکز اسید لوئیسی باعث ایجاد سازوکار انتقال تسهیل یافته شد و عبوردهی CO2 را افزایش داد، اگرچه به دلیل برقراری پیوندهای هیدروژنی زمینۀ پلیمری سفت شد و سازوکار انتقال تسهیل یافته در غشای بهینه تنها توانست عبوردهی CO2 را 12/4 درصد نسبت به غشای خالص افزایش دهد. ازطرف دیگر، سفتی زمینۀ پلیمری باعث کاهش عبوردهی N2 شد و باعث افزایش 136 درصدی انتخابگری CO2/N2 در غشای بهینه درمقایسه با غشای خالص شد، به طوری که توانست از خط بالایی رابسون به آسانی عبورکند.

چکیده: 

We expand a new generalization of the two-dimensional differential trans-form method. The new generalization is based on the two-dimensional differ-ential transform method, fractional power series expansions, and Conformable fractional derivative. We use the new method for solving a nonlinear con-formable fractional partial differential equation and a system of Conformable fractional partial differential equation. Finally, numerical examples are pre-sented to illustrate the preciseness and effectiveness of the new technique.

چکیده: 

This paper presents a new sub-equation method based on an auxiliary equation which is implemented via the well-known generalized Kudryashov method, to construct new traveling waves to the Telegraph equation with time and space Conformable derivatives. To illustrate its effectiveness, it was tested for seeking traveling wave solutions to the (1+1)-Telegraph equation with space-time Conformable derivatives. With the help of Maple Software we derive some new solitary waves solutions. It can be concluded that the proposed method is an accurate tool for solving several kind of nonlinear evolution equations.

چکیده: 

During the past years, a wide range of distinct approaches has been exerted to solve the nonlinear fractional differential equations (NLFDEs). In this paper, the invariant subspace method (ISM) in conjunction with the fractional Sumudu’ s transform (FST) in the Conformable context is formally adopted to deal with a nonlinear Conformable time-fractional dispersive equation of the fifth-order. As an outcome, a new exact solution of the model is procured, corroborating the exceptional performance of the hybrid scheme.
