Multicriteria analysis for behavioral segmentation

open access: yesJournal of Telecommunications and Information Technology, 2004
Behavioral segmentation is a process of finding the groups of clients with similar behavioral patterns. The basic tool for segmentation is a clustering algorithm. However, the clusters generated by the algorithm depend on the preprocessing steps as well

Biphoton Waveforms of Photon Pair from Velocity‐Selective Atoms in a Doppler‐Broadened Atomic Ensemble

open access: yesAdvanced Photonics Research, EarlyView.
Telecom‐band quantum light sources have significant practical applications in this domain. This study reports the high‐performance telecom‐wavelength biphoton generation from a hot vapor cell of 87Rb. For the first time, the beat phenomenon in the autocorrelation function of the signal photon with telecom wavelength due to the velocity‐selective ...

Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber

open access: yesAdvanced Photonics Research, EarlyView.
Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Telecommunications at the crossroads in India

open access: yesIIMB Management Review, 2015
AbstractThe telecommunications sector is going through an interesting phase in its evolution. Cellular mobile service providers have been at the root of the massive expansion in the number of subscribers and usage. Since last year the pace of growth has slowed down and it is increasingly clear that revenues from voice services alone will not be ...

Stimulated Raman Scattering with Optical Vortex Beams

open access: yesAdvanced Photonics Research, EarlyView.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.
