Two new ternary compounds in the TiO2-TiC system, Ti5C2O6 and Ti3C2O2, are reported for the first time based on ab initio evolutionary algorithm. Ti5C2O6 has a tube-structure in which sp(1) hybridized carbon chains run through the lattice along the b-axis; while in the Ti3C2O2 lattice, double TiO6 polyhedral are separated by the non-coplanar sp(2)(More)
An electronic voting (e-voting) system is a voting system in which the election data is recorded, stored and processed primarily as digital information. There have been several studies on electronic voting technology embracing both electronic means of casting a vote and electronic means of counting votes. In this paper we have proposed a model(More)
We advance a method used to analyse the neutrino properties (masses and mixing) in the seesaw mechanism. Assuming quark-lepton symmetry and hierarchical light neutrino masses, we establish rather simple relations between the light and the heavy neutrino parameters in the favored regions of the solar and the atmospheric neutrino experiments. A empirical(More)
