Localized Boundary-Domain Integro-partial Differential Formulations for Transient Scalar Transport Problems
International Journal of Applied and Computational Mathematics - Tập 3 - Trang 2189-2204 - 2016
Okey Oseloka Onyejekwe
Integro-partial differential equations, though very challenging can still be solved using conventional numerical techniques. Although these problems have been severally solved, it is still noticeable how little has been said about them in boundary element method (BEM) literature. A major reason for this is that for those problems where an encounter with the problem domain becomes a necessity, BEM’... hiện toàn bộ

Non-stationary Solitary Wave Solution for Damped Forced Kadomtsev–Petviashvili Equation in a Magnetized Dusty Plasma with q-Nonextensive Velocity Distributed Electron
International Journal of Applied and Computational Mathematics - Tập 7 - Trang 1-20 - 2021
Santanu Raut, Ashim Roy, Kajal Kumar Mondal, Prasanta Chatterjee, Naresh M. Chadha
Reductive perturbation method (RPM) is used to obtain damped forced Kadomtsev–Petviashvili (DFKP) equation for the ion acoustic waves (IAWs) in a magnetized dusty plasma comprising electrons abiding by q-nonextensive velocity distribution, in the presence of external periodic force along with a damping term. A nonstationary solitary wave solution of IAW under the influence of forcing and damping t... hiện toàn bộ
Flexible Setup Cost and Deterioration of Products in a Supply Chain Model
International Journal of Applied and Computational Mathematics - Tập 2 - Trang 25-40 - 2015
Biswajit Sarkar, Bimal Kumar Sett, Gargi Roy, Adrijit Goswami
Product reliability is of significant importance in today’s technological world. People rely more and more upon the sustained functioning of machinery and complex equipments for purposes such as health, economic welfare, safety, to name just a few. Thus, in a business arena, it is critical to assess the reliability of new products. In this model, a two echelon supply chain model with variable setu... hiện toàn bộ
Computational Investigation of Stefan Blowing Effect on Flow of Second-Grade Fluid Over a Curved Stretching Sheet
International Journal of Applied and Computational Mathematics - Tập 7 - Trang 1-16 - 2021
R. J. Punith Gowda, Haci Mehmet Baskonus, R. Naveen Kumar, B. C. Prasannakumara, D. G. Prakasha
Non-Newtonian fluids have extensive range of applications in the field of industries like plastics processing, manufacturing of electronic devices, lubrication flows, medicine and medical equipment. Stimulated from these applications, a theoretical analysis is carried out to scrutinize the flow of a second-grade liquid over a curved stretching sheet with the impact of Stefan blowing condition, the... hiện toàn bộ
Approximate Analytical Solutions of Generalized Zakharov–Kuznetsov and Generalized Modified Zakharov–Kuznetsov Equations
International Journal of Applied and Computational Mathematics - Tập 7 - Trang 1-25 - 2021
Santanu Raut, Subrata Roy, Rishi Raj Kairi, Prasanta Chatterjee
This paper investigates the generalized Zakharov–Kuznetsov (GZK) equation and generalized modified Zakharov–Kuznetsov equation in the presence of external periodic forcing term together with damping. An approximate analytical solution is obtained by employing the direct assumption technique. The framework staged here reveals number of beautiful wave features such as positive amplitude soliton, rar... hiện toàn bộ

Different Wave Structures to the (2 + 1)-Dimensional Generalized Bogoyavlensky–Konopelchenko Equation
International Journal of Applied and Computational Mathematics - Tập 5 - Trang 1-12 - 2019
R. Pouyanmehr, K. Hosseini, R. Ansari, S. H. Alavi
The purpose of the present work is to confirm the existence of different wave structures for the (2 + 1)-dimensional generalized Bogoyavlensky–Konopelchenko (2D-gBK) equation describing nonlinear waves in applied sciences. In this respect, based on the Hirota’s bilinear form and various test schemes, a variety of exact solutions, including breather-wave, rational, double soliton, mixed-type, cross... hiện toàn bộ
Generalized Trapezoidal Intuitionistic Fuzzy Soft Sets in Risk Analysis
International Journal of Applied and Computational Mathematics - Tập 5 - Trang 1-18 - 2019
Soumi Manna, Tanushree Mitra Basu, Shyamal Kumar Mondal
In medical sciences, diagnosis of a disease of a patient needs to be very potent and realizable. In this article we have given a mathematical approach that can help a doctor for making a decision about a patient whether he/she is a diabetic or not. In this regard, firstly we have introduced the notion of generalized trapezoidal intuitionistic fuzzy soft set. Secondly, we have employed a new decisi... hiện toàn bộ
On the Discrete q-Hermite Matrix Polynomials
International Journal of Applied and Computational Mathematics - Tập 3 - Trang 3147-3158 - 2016
Ahmed Salem
There are two definitions for the discrete q-Hermite polynomials, one of them is defined for $$01$$ . This paper is devoted to extend these definitions to the discrete q-Hermite matrix polynomials by means of the generating matrix functions. Explicit expressions and Rodrigues-type formulas for the discrete q-Hermite matrix polynomials are obtained. Some recurrence relations for these matrix polyno... hiện toàn bộ
