Consumer Expenditure Distribution in India, 1983-2007: Evidence of a Long Pareto Tail
Abhik Ghosh, Kausik Gangopadhyay, B. Basu
This work presents an empirical study of the evolution of the consumer expenditure distribution in India during 1982-2007. We have used the National Sample Survey Organization data…
Land cover classification using fuzzy rules and aggregation of contextual information through evidence theory
Arijit Laha, Nikhil R. Pal, J. Das
Land cover classification using multispectral satellite image is a very challenging task with numerous practical applications. We propose a multi-stage classifier that involves fuz…
Designing fuzzy rule based classifier using self-organizing feature map for analysis of multispectral satellite images
Nikhil R. Pal, Arijit Laha, J. Das
We propose a novel scheme for designing fuzzy rule based classifier. An SOFM based method is used for generating a set of prototypes which is used to generate a set of fuzzy rules.…
Analyzing Non-Extensivity of -spectra in Relativistic Heavy Ion Collisions at GeV
Bhaskar De, Gautam Sau, S. K. Biswas +2
The transverse momentum spectra of secondary particles produced in , and interactions at GeV at different centralities have been studied…
Quantum mechanics in de Sitter space
Subir Ghosh, Salvatore Mignemi
We consider some possible phenomenological implications of the extended uncertainty principle, which is believed to hold for quantum mechanics in de Sitter spacetime. The relative…
Ergodic properties of sum- and max-stable stationary random fields via null and positive group actions
Yizao Wang, Parthanil Roy, Stilian A. Stoev
We establish characterization results for the ergodicity of stationary symmetric -stable (SS) and -Frechet random fields. We show that the result of Samorodnitsky [Ann. Pr…
