  • Marchon, N.; Naik, G.M. (Control Instrumentation Systems, Proceedings of CISCON 2018, Ed. by: Shreesha, C.;Gudi, R.D., Lecture Notes in Electrical Engineering; 2019; 113-121.)
    A unique methodology employing a linear phase finite impulse response (FIR) low pass filter (LPF) was proposed with an attempt to mitigate passband and stopband ripples due to Gibb's phenomenon. The three regions of the ...
  • Gaonkar, V.N.; Dias, E.T.; Das, A.; Nigam, A.K.; Priolkar, K.R. (Journal of Magnetism and Magnetic Materials. 488; 2019; ArticleID_165357.)
    The structural and magnetic interactions in stoichiometric (Mn sub(3)SnC), carbon deficient (Mn sub(3)SnC sub(0.8)) and tin deficient (Mn sub(3)Sn sub(0.85)C) antiperovskite compounds are studied using X-ray absorption ...
  • Nevgi, R.; Das, G.; Acet, M.; Priolkar, K.R. (Journal of Alloys and Compounds. 797; 2019; 995-1001.)
    Martensitic transition temperature steadily decreases in Ni sub(2-x)Fe sub(x)Mn sub(1.5)In sub(0.5) and is completely suppressed at x = 0.2. Despite suppression of martensitic transition, Ni sub(1.8)Fe sub(0.2)Mn sub(1.5)In ...
  • Baidya, T.; Murayama, T.; Nellaiappan, S.; Katiyar, N.; Bera, P.; Safonova, O.; Lin, M.; Priolkar, K.R.; Kundu, S.; Rao, B.S.; Steiger, P.; Sharma, S.; Biswas, K.; Pradhan, S.; Nakka, L.; Malviya, K.D.; Haruta, M. (Journal of Physical Chemistry C. 123(32); 2019; 19557-19571.)
    Co sub(3) O sub(4) with spinel structure shows CO oxidation activity at very low temperature under dry condition. This study aims at finding the origin of the unique catalytic activity of Co species in Co sub(3) O sub(4) ...
  • Jeyakanthan, M.; UmaSubramanian; Tangsali, R.B.; Jose, R.; Saravanan, K.V. (Journal of Materials Science: Materials in Electronics. 30(15); 2019; 14657-14668.)
    Dielectric constant epsilon' and dielectric loss epsilon" were measured in the frequency range of 500 Hz-3 MHz from room temperature (RT) to 350 degrees C for CoWO sub(4) and CoWO sub(4)/PbWO sub(4) nanocomposites sintered ...
  • Pereira, J.; Singh, T.; Arumugam, S. (Discrete Applied Mathematics. NYP; 2019; NYP.)
    We present several basic results on ecg and use this parameter to prove that any connected graph G can be embedded as an induced subgraph of a graceful graph and as an induced subgraph of an eulerian graceful graph.
  • Santhoshkumar, B.; LokeswaraRao, P.; Ramanathan, K.V.; Bera, A.K.; Pahari, B. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030570.)
    Recently it has been reported that low levels of Bi nonstoichiometry (only plus or minus 1 atomic percent) in the nominal starting composition of Na sub(0.5) Bi sub(0.5) TiO sub(3) (NBT) ceramics can lead to dramatic changes ...
  • Kothawale, M.M.; Tangsali, R.B.; Meena, S.S.; Prasad, N.K.; Gangwar, A. (Journal of Superconductivity and Novel Magnetism. 32(7); 2019; 2141-2147.)
    Variations of Curie temperature and strength of magnetic phases with sintering temperature and Ni concentration is investigated in the present work. The AC susceptibility studies show a decrease in Curie temperature (TC) ...
  • Soares, B.P.; Desa, J.A.E.; Krishna, P.S.R. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030247.)
    Oxides of La, Nd and Pr have been included both singly and as pairs in Alumino-Germanate glasses at molar percentages varying from 5 percent to 10 percent. The glass transition temperatures were found by differential thermal ...
  • Gaonker, C.G.F.; Alavani, B.K.; Das, A.; Pai, R.V. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030016.)
    In this paper, we analyze superfluid, insulator and various magnetic phases of ultracold spin-1 bosonic atoms in two-dimensional optical superlattices. Our studies have been performed using Cluster Mean Field Theory. ...
