In this paper a coupled coincidence point theorem is established in a fuzzy metric space which is assumed to be G-complete.

The Size, structure, morphology and composition of the as-synthesized samples were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive Xray (EDX) spectroscopy. The optical properties of the samples were investigated by ultraviolet–visible (UV-vis) and photoluminescence (PL) spectroscopies. The magnetic property was studied with the vibrating sample magnetometer (VSM). Finally, the possible formation mechanism for synthesized tin oxide has also been proposed 2014-12-26T00:00:00Z https://ir.vidyasagar.ac.in/jspui/handle/123456789/924 Title: Reliability Assessment for Cold Standby System Under Progressively Type-II Censoring with Binomial Removals Authors: Shi, Yimin; Liu, Fen Abstract: The cold standby system is widely used to improve system reliability. Supposing that the lifetime of each unit follows gamma distribution, this article deals with the reliability assessment for cold standby system under Type-II progressive censoring with binomial removals. Maximum likelihood and Bayesian estimations for the scale parameter, probability of removal and reliability indices of system are derived. Besides, we demonstrate the effects of removal probability on the estimators and some numerical results by Monte Carlo simulation for illustrative purposes 2014-12-26T00:00:00Z https://ir.vidyasagar.ac.in/jspui/handle/123456789/922 Title: Squeezing and Entanglement in Quadratically-Coupled Optomechanical System Authors: Mukherjee, Kousik; Jana, Paresh Chandra Abstract: An operator analytic solution of quadratically-coupled optomechanical system using Hisenberg equation of motion and short-time dynamics to investigate the nonclassical phenomena i.e. squeezing and entanglement for different modes of the system. These effect on strong coupling interaction between macroscopic membrane and cavity resonator neglecting the effect of dissipation and environmental noise have been studied. Phonon properties of the system under that conditions are also investigated. Temporal variation of these nonclassical properties for different strength of coupling are also reported 2014-12-26T00:00:00Z
