We study the Cauchy problem for focusing nonlinear Kundu-Eckhaus equation and construct long time asymptotic expansion of its solution in fixed space-time cone with $C(x_1,x_2,v_1,v_2)=\{(x,t)\in\Re^2:x=x_0+vt$ $x_0\in[x_1,x_2],v\in[v_1,v_2] \}$. By using inverse scattering transform, Riemann-Hilbert approach $\overline\partial$ steepest descent method we obtain lone behavior solution, at same ...
In this paper, the improved -expansion method is proposed to solve the Kundu–Eckhaus equation and Gerdjikov–Ivanov model. The applied method are analytical methods to obtaining the exact solutions of nonlinear equations. Here, the aforementioned methods are used for constructing the soliton, periodic, rational, singular and solitary wave solutions for solving some equations. We obtained furthe...
‎Recently‎, ‎a new distribution‎, ‎named as extended generalized exponential distribution‎, ‎has been introduced by Kundu and Gupta (2011). ‎In this paper‎, ‎we consider the extended generalized exponential distribution with known shape parameters α and β. ‎At first‎, ‎the exact expressions for marginal and product moments of o...
The key objective of the current manuscript was to investigate exact solutions fractional perturbed Radhakrishnan–Kundu–Lakshmanan model. For this purpose, we applied two reliable and efficient approaches; specifically, modified simple equation (MSE) exponential rational function (ERF) techniques. methods considered in paper offer for problems nonlinear theory mathematical physics practice. We ...
Kundu, M.K., B.B. Chaudhuri and D. Dutta Majumder, A parallel graytone thinning algorithm (PGTA), Pattern Recognition Letters 12 (1991) 491-496. A parallel graytone thinning algorithm (PGTA) is proposed in this paper. This algorithm is a generalization of a well-known two-tone thinning algorithm of Zhang and Suen (1984) and is equally applicable for both graytone and two-tone images. The perfor...
This paper is concerned with the estimators problems of the generalized Weibull distribution based on Type-I hybrid progressive censoring scheme (Type-I PHCS) in the presence of competing risks when the cause of failure of each item is known. Maximum likelihood estimates and the corresponding Fisher information matrix are obtained. We generalized Kundu and Joarder [7] results in the case of the...

The main aim of this paper is to obtain some new common fixed point theorems for Geraghty’s type contraction mappings using the monotone property with two metrics and to give some examples to illustrate the main results. Further, by using our main results, we prove some results about multidimensional common fixed points. Our results generalize and extend some recent results given by Kadelburg e...
Green Batteries In article number 2206249, Dipan Kundu, Erlantz Lizundia, Markus Niederberger, and co-workers design a green, fully transient high performance Zn-ion battery having an organic cathode renewable hydrogel electrolyte based on biopolymers potentially extracted from marine- lignocellulosic-wastes. With its compostable cell packaging low contribution of materials to the cradle-to-gat...
