Comparison of K-Medoids Method and Analytical Hierarchy Clustering on Students' Data Grouping

open access: yesJOIV : International Journal on Informatics Visualization, 2023
One sign of how successfully the educational process is carried out on campus in a university is the timely graduation of students. This study compares the Analytic Hierarchy Clustering (AHC) approach with the K-Medoids method, a data mining technique for categorizing student data based on school origin, region of origin, average math score, TOEFL, GPA,

Multiscalar B − L extension with A4 symmetry for fermion mass and mixing with co-bimaximal scheme

open access: yesPhysics Letters B, 2021
We construct a multiscalar and nonrenormalizable B−L extension of the standard model with A4 group which successfully explains the recent observed neutrino oscillation pattern.

Fluoride in the drinking water and dental caries experience by tooth surface susceptibility among adults

open access: yesBMC Oral Health, 2021
Background Dental caries is the most prevalent non-communicable health condition globally. The surface-based susceptibility hierarchy indicates that surfaces in the same group have similar susceptibility to caries, where the most susceptible group ...
