    Class of bounded operators associated with an atomic system
    (Tamkang University editor@staff.tku.edu.tw, 2015) Johnson, P.S.; Ramu, G.
    K-frames, more general than the ordinary frames, have been introduced by Laura G?vru?a in Hilbert spaces to study atomic systems with respect to a bounded linear operator. Using the frame operator, we find a class of bounded linear operators in which a given Bessel sequence is an atomic system for every member in the class.

    Design of an automated dispenser unit
    (2014) Anoop, Raghav, S.; Ajith, S.R.; Murali, P.; Ramu, G.; Bhargav, S.D.B.; Sajeesh, Kumar, M.P.; Bhat, N.; Ananthasuresh, G.K.
    This paper presents our work on developing an automated micropositioner and a low cost disposable dispenser module having a disposable dispenser core. The dispenser core is made up of Polydimethylsiloxane (PDMS). Once the user specifies the dispensing location in the Graphical User Interface (GUI), the movement of the micropositioner is automatic. The design, fabrication and characterization results of the dispenser module are also presented. The dispensing experiments are performed with Di-Ethanol Amine as the working reagent. The minimum dispensed volume achieved is about 4 nL. � 2014 IEEE.

    Frame operators of K-frames
    (Springer Nature, 2016) Ramu, G.; Johnson, P.S.
    A close relation between frames on a separable Hilbert space H and positive invertible bounded operators is known. In this paper, it is shown that for a bounded operator K on H, there is a relationship between K-frames and quotient operators. Results on K-frames have been proved through operator-theoretic results on quotient of bounded operators. © 2016, Sociedad Española de Matemática Aplicada.
