Establishing critical limits of sulphur for groundnut (Arachis hypogaea)
Autor: RAHUL KUMAR, G C HAZRA, RUMA DAS, S P MAJUMDER, DHANESHWAR PADHAN, A C DAS
Publikováno v: The Indian Journal of Agricultural Sciences, Vol 89, Iss 11 (2019)
Sulphur is essential for growth and development of groundnut (Arachis hypogaea L.). Deficiency of S is widespread in soils of India, and is becoming a major concern for the quality and yield of groundnut crop. Therefore, a study was conducted to inve

A Note on Burg’s Modified Entropy in Statistical Mechanics
Autor: Amritansu Ray, S. K. Majumder
Publikováno v: Mathematics, Vol 4, Iss 1, p 10 (2016)
Burg’s entropy plays an important role in this age of information euphoria, particularly in understanding the emergent behavior of a complex system such as statistical mechanics. For discrete or continuous variable, maximization of Burg’s Entropy

Aperture Averaged BER Performance Analysis of a non-Hermitian coherent optical OFDM FSO system with polarization diversity
Autor: M. Shariful Islam, Md. Imamul Hassan Bhuiyan, S. P. Majumder
Publikováno v: 2020 11th International Conference on Electrical and Computer Engineering (ICECE).
In this article, we evaluated the amount of improvement in receiver sensitivity for a non-Hermitian OFDM FSO system with polarization diversity due to using aperture averaging, a very effective technique of fading mitigation. Due to the presence of a

Structural and Electrochemical Characterization of Pure LiFePO4 and Nanocomposite C-LiFePO4 Cathodes for Lithium Ion Rechargeable Batteries
Autor: Arun Kumar, R. Thomas, N. K. Karan, J. J. Saavedra-Arias, M. K. Singh, S. B. Majumder, M. S. Tomar, R. S. Katiyar
Publikováno v: Journal of Nanotechnology, Vol 2009 (2009)
Pure lithium iron phosphate (LiFePO4) and carbon-coated LiFePO4 (C-LiFePO4) cathode materials were synthesized for Li-ion batteries. Structural and electrochemical properties of these materials were compared. X-ray diffraction revealed orthorhombic o

Performance Analysis of a Non-Hermitian OFDM Optical DQPSK FSO Link over Atmospheric Turbulent Channel
Autor: S. P. Majumder, M. Shariful Islam
Publikováno v: Journal of Optical Communications.
A free-space optic (FSO) system model considering non-Hermitian orthogonal frequency division multiplexing (OFDM) modulation followed by optical differential quadrature phase shift keying (DQPSK) modulation is proposed. Analysis is presented for an O

BER performance limitations due to inter-core crosstalk in a multi-core fiber-optic transmission system
Autor: Afzal Hossain, S P Majumder
Publikováno v: Optik. 232:166582
An analytical approach is developed to evaluate the amount of crosstalk due to inter-core coupling and its limitations on the Bit Error Rate (BER) performance of a fiber link length of 1000 m with a homogeneous multi-core optical fiber (MCF) with a d
