Real-Time Robust Heart Rate Estimation From Wrist-Type PPG Signals Using Multiple Reference Adaptive Noise Cancellation
TL;DR: A robust HR estimation algorithm for wrist-type PPG signals using multiple reference adaptive noise cancellation (ANC) technique—termed here as “MURAD” that gives lower average absolute error compared to state-of-the art methods is proposed.
Journal ArticleDOI
The 10% Gd and Ti co-doped BiFeO3: A promising multiferroic material
M. A. Basith,Areef Billah,M. A. Jalil,Nilufar Yesmin,Mashnoon Alam Sakib,Emran Khan Ashik,S. M. Enamul Hoque Yousuf,Sayeed Shafayet Chowdhury,Md. Sarowar Hossain,Shakhawat H. Firoz,Bashir Ahmmad +10 more
TL;DR: In this paper, the structural analysis and phase identification of multiferroic ceramics were performed using Rietveld refinement, and the results indicated that the substitution of 10% Gd and Ti in place of Bi and Fe, respectively, in BiFeO3 significantly enhances its multi-dimensional properties.
