The fractal interpolation functions with appropriate iterated function systems (IFSs) pro- vide a method to perturb and approximate an arbitrary function. Sierpinski Gasket (SG) is generated by three mappings in the plane, each a similarity with ratio 1 2 and fixed points the vertices of a triangle. In this talk, we discuss the non-stationary fractal function on the SG. Also, we discuss the fractal dimension of the proposed interpolants under suitable assumption on the corresponding IFS. F...

We study the multi-wavelength properties of a massive void galaxy - I Zw 81. The galaxy's structural decomposition reveals a strong bar at the center accompanied by a low surface brightness disk. The SED analysis of the galaxy indicate that the galaxy is star-forming. The central region of the galaxy comprising the bar shows signs of strong far- and near-UV emission while there is a dearth of recent star formation at the galactic outskirts. We comment on the role of bar and minor merger inter...

Analysis of heart sound signals provides ample features to diagnose cardiovascular diseases (CVDs) at an early stage. However, the role of cardiac auscultation is limited only to performing the preliminary screening. It is due to the subjectivity of nature in the diagnosis. Automatic analysis of heart sounds will address this issue as well as it will also reduce the burden of the already-stretched medical facility. This paper proposes a lightweight 1D-CNN model to analyse and classify heart ...
