Analytic solution of system of singular nonlinear differential equations with Neumann-Robin boundary conditions arising in astrophysics
Randhir Singh
In this paper, we propose a new approach for the approximate analytic solution of system of Lane-Emden-Fowler type equations with Neumann-Robin boundary conditions. The algorithm i…
Solving coupled Lane-Emden equations by Green's function and decomposition technique
Randhir Singh
In this paper, the Green's function and decomposition technique is proposed for solving the coupled Lane-Emden equations. This approach depends on constructing Green's function bef…
A multiple-frame approach of crop yield estimation from satellite remotely sensed data
Sumanta Kumar Das, Randhir Singh
Many studies have recently explored the information from the satellite-remotely sensed data (SRSD) for estimating the crop production statistics. The value of this information depe…
Performance modeling of electro-optical devices for military target acquisition
Sumanta kumar das, R. S. Singh
Accurate predictions of electro-optical imager performance are important for defence decision-making. The predictions serve as a guide for system development and are used in war ga…
Performance of Kriging Based Soft Classification on WiFS/IRS- 1D image using Ground Hyperspectral Signatures
Sumanta Kumar Das, Randhir Singh
Hard and soft classification techniques are the conventional ways of image classification on satellite data. These classifiers have number of drawbacks. Firstly, these approaches a…
