Dielectric behavior and impedance spectroscopy of Niobium substituted Lanthanum based orthovanadates at high temperatures
Ashok Kumar, Vikas N. Thakur, Ajay Kumar +3
We present the detailed study of the temperature dependent dielectric properties, impedance spectroscopy and electrical conductivity of LaVNbO ( 0-1) samples pr…
Non-parametric Ensemble Empirical Mode Decomposition for extracting weak features to identify bearing defects
Anil Kumar, Yaakoub Berrouche, Radosław Zimroz +5
A non-parametric complementary ensemble empirical mode decomposition (NPCEEMD) is proposed for identifying bearing defects using weak features. NPCEEMD is non-parametric because, u…
Efficient Algorithms and Hardness Results for the Weighted -Server Problem
Anupam Gupta, Amit Kumar, Debmalya Panigrahi
In this paper, we study the weighted -server problem on the uniform metric in both the offline and online settings. We start with the offline setting. In contrast to the (unweig…
Structural, vibrational and electronic properties of Nb substituted orthovanadates LaVNbO
Ashok Kumar, Anurag Sharma, Madhav Sharma +3
We investigate the structural, vibrational, morphological, and electronic properties of Nb substituted orthovanadate LaVNbO samples prepared by the solid-state reac…
Laser based optical interferometer manometer design for primary pressure standard in India
Manoj Das, Sandip Kumar Ghosh, Kuldeep Kumar +3
The SI unit of pressure, i.e. Pascal is realized with mechanical devices such as ultrasonic interferometer manometers and pressure balances for the pressure range 1 Pa to 100 kPa.…
Effect of the growth orientation on the physical properties of SrCoNbO thin films
Ajay Kumar, Ramcharan Meena, M. Miryala +2
We study the effect of the growth orientation on the structural, electronic, and hence transport properties of SrCoNbO thin films grown on the orthorhombic NGO(100) and cub…
