  • Transmuted Exponentiated Kumaraswamy Distribution 
    Joseph, Jeena; Ravindran, Meera (ResearchGate, 2023-03)
    In this paper, a generalization of the Exponentiated Kumaraswamy distribution referred to as the Transmuted Exponentiated Kumaraswamy distribution is proposed. The new transmuted distribution is developed using the ...
  • Taxonomical studies of dragonfly nymphs (Odonata, Libellulidae) using their exuviae 
    Adambukulam, Shaun Paul; Kakkassery, Francy K. (Entomon, 2023-12-31)
    Taxonomic studies of dragonfly nymphs were done up to species level using their exuviae.Exuviae, being the last instar larval skin, possess all larval features. These features can be used for theidentification of odonate ...
