TL;DR: A preliminary study on photoplethysmogram (PPG) based biometry system is presented here and 100% accuracy is achieved for 15 number of data captured using Biopac MP 45.
Abstract: A preliminary study on photoplethysmogram (PPG) based biometry system is presented here. PPG is a physiological signal related to cardiac output and blood flow saturation in body. Recently it is reported that being an automatic physiological phenomenon PPG and other biosignals can be used as biometric parameters for human authentication. In this work, 12 number of features are extracted from filtered PPG and its derivatives and Linear Discriminant Analysis (LDA) is used for classification over the statistical parameters extracted from the feature set. 100% accuracy is achieved for 15 number of data captured using Biopac MP 45.

TL;DR: In this paper, a facile one-pot synthesis method is employed to prepare ultra small ternary nano-alloy catalysts for boosting the EOR in alkaline DEFCs, and a substantial rise of peak power density is obtained by more than 241% higher as compared to Pt, 78%, and 51%, compared to the bimetallic Ni41Pt59 and Pd55Pt45 catalysts, respectively.
Abstract: The present investigations explore the important contribution of transitional metal/metal oxide/hydroxide in ternary alloys of Ni, Pd, and Pt NPs for boosting the EOR in alkaline DEFCs. A facile one-pot synthesis method is employed to prepare ultra small ternary nano-alloy catalysts. The impact of Ni/NiO /Ni(OH)2 species in EOR on Pd/Pd catalyst is strongly recognized by the diminution of overvoltage ∼ 546 mV in case of the multi metallic surface. The oxy/hydroxy species of the multi-metallic formulation of Ni29Pd34Pt37 not only trigger the electrode kinetics at the lower electro-chemical bias-potential but also facilitate towards sustained product formation and electro-extraction as manifested by the output power. A substantial rise of peak power density is obtained by more than 241% higher as compared to Pt, 78%, and 51%, compared to the bimetallic Ni41Pt59 and Pd55Pt45 catalysts, respectively. The increase of CH3CO2− and CO32− yields on the ternary catalyst compared to its unary/binary counterparts, further confirms the catalytic preeminence of the combinatorial formulation of Ni29Pd34Pt37 in the present investigation.
