Bioacoustic signal analysis through complex network features
Vimal Raj, Mohanachandran Nair Sindhu Swapna, Sankaranarayana Iyer Sankararaman
Izvirni znanstveni članek
Oznake: bioacoustic signal;graph theory;complex network;lung auscultation;
The paper proposes a graph-theoretical approach to auscultation, bringing out the potential of graph features in classifying the bioacoustics signals. The complex network analysis of the bioacoustics signals - vesicular (VE) and bronchial (BR) breath sound - of 48 healthy persons are carried out ...

Allotropic transformation instigated thermal diffusivity of soot nanofluid
Mohanachandran Nair Sindhu Swapna, Vimal Raj, Sankaranarayana Iyer Sankararaman
Izvirni znanstveni članek
Oznake: petrol soot;thermal lens;thermal diffusivity;
This paper employs the sensitive single-beam thermal lens technique for analyzing the thermal behavior of gasoline soot containing allotropes of carbon by preparing its nanofluid (NF). The soot, annealed at different temperatures up to 400 ○C (the samples), used for preparing the NF, is found to enh ...

Hidden periodicity in Stripe 82 with Saraswati supercluster
Vimal Raj, Mohanachandran Nair Sindhu Swapna, Sankaranarayana Iyer Sankararaman
Izvirni znanstveni članek
Oznake: galaxy distribution;fractal analysis;multifractals;lacunarity;Saraswati supercluster;Stripe 82;
The manuscript attempts to explore the periodicity in the distribution of galaxies in the recently reported Saraswati supercluster and the Stripe 82 region containing it as an example. The report of 120 Mpc periodicity in the Abell galaxy clusters by power spectrum analysis is the motivation behi ...
