A wave-function ansatz method for calculating field correlations and its application to the study of spectral filtering and quantum dynamics of multi-emitter systems
Sumanta Das, Liang Zhai, Mantas Čepulskovskis +4
We develop a formalism based on a time-dependent wave-function ansatz to study correlations of photons emitted from a collection of two-level quantum emitters. We show how to simul…
Cooling Rate Effects on the Structure of 45S5 Bioglass: Computational and Experimental Evidence of Si--P Avoidance
Pratik Bhaskar, Yashasvi Maurya, Rajesh Kumar +10
Due to its ability to bond with living tissues upon dissolution, 45S5 bioglass and related compositions are promising materials for the replacement, regeneration, and repair of har…
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…
Modeling Competitive Dynamics with Heterogeneous Lanchester Equations: Insights from Kursk Battle
Sumanta Kumar Das
This study extends the classical generalized homogeneous Lanchester model to a heterogeneous situation. The complexity of parameter estimation in a heterogeneous situation is handl…
