Particle size controlled magnetic loss in magnetite nanoparticles in RF-microwave region
Mudra Jadav, S. P. Bhatnagar
Frequency dependant complex magnetic permeability is used to understand RF-microwave behaviour of magnetic nanoparticles in the frequency range 250 MHz to 3 GHz. The stable dispers…
First Time-Resolved CCD Photometry and Time-series Analysis of NSV 13601
Virabhadrasinh A. Gohil, Sachchidanand Prakash Bhatnagar
We present the first results of a time-resolved CCD photometric and time-series analysis of NSV 13601, a variable star of Pegasus constellation. The 14" SCT of Maharaja Krishnakuma…
Time-resolved CCD photometry and time-series analysis of RR Lyrae type RR Gem star
V. A. Gohil, S. P. Bhatnagar
We present the results of a time-resolved photometric and time-series analysis of a RR Lyrae type star RR Gem. The main results are as follows: We found RR Gem's pulsation period,…
Influence of magnetic field on evaporation of a ferrofluid droplet
Mudra Jadav, R. J. Patel, R. V. Mehta
Influence of magnitude and direction of static magnetic field applied on a drying drop of a laboratory synthesized water base ferrofluid placed on a plane glass plate is investigat…
A Novel Digital Watermarking Algorithm using Random Matrix Image
Mahimn Pandya, Hiren Joshi, Ashish Jani
The availability of bandwidth for internet access is sufficient enough to communicate digital assets. These digital assets are subjected to various types of threats. [19] As a resu…
Modified Confinement Model for Size Dependent Raman Shift and Linewidth of Silicon Nanocrystals
Sanjeev K. Gupta, Prafulla K. Jha
A modified phonon confinement model considering the size distribution, an improved phonon dispersion curve and a confinement function is developed for the calculation of size depen…
