Solutions of second-order partial differential equations in two independent variables using method of characteristics
(nternational Journal of Engineering and Mathematical Sciences, 2013-06-01)
In this paper we have classified second order linear PDEs into three types, hyperbolic, parabolic and elliptic. Hyperbolic equations have two distinct families of (real) characteristic curves, parabolic equations have a ...
Rabi oscillations, entanglement and teleportation in the anti-Jaynes-Cummings model
(Cornell University, 2021)
This paper provides a scheme for generating maximally entangled qubit states in the anti-JaynesCummings interaction mechanism, so called entangled anti-polariton qubit states. We demonstrate
that in an initial vacuum-field, ...
Nitrogen Doping of Hexagonal and Cubic Ge2Sb2Te5Nanocrystals: An Ab Initio Study
(World Scientific Publishing Company, 2018-12-17)
The effect of nitrogen doping on the structural, electronic and optical properties of hexagonal and cubic Ge2Sb2Te5 (GST) has been investigated from first principles. The nitrogen content was set to 10 at.% and 25 at.%, ...
Annealing efect on the structural and optical behavior of ZnO:Eu3+ thin flm grown using RF magnetron sputtering technique and application to dye sensitized solar cells
(Nature Publishing Group, 2020)
Eu-doped ZnO (ZnO:Eu3+) thin flms deposited by RF magnetron sputtering have been investigated to
establish the efect of annealing on the red photoluminescence. PL spectra analysis reveal a correlation
between the ...
Ab Initio study of the electronic and optical properties of hexagonal and cubic Ge2Sb2Te5
(African Review of Physics, 2015-04)
The electronic and optical properties of hexagonal and cubic Ge 2 Sb 2 Te 5 have been calculated using the QUANTUM ESPRESSO and Yambo codes. The study has considered the variation of electronic band gaps with lattice ...
Ab initio study of the structural, vibrational and thermal properties of Ge2Sb2Te5
(International Journal of Computational Materials Science, 2015-05-12)
The structural, vibrational and thermal properties of hexagonal as well as cubic Ge2Sb2Te5 (GST) have been calculated from first principles. The relative stability of the possible stacking sequences of hexagonal GST has ...
Effect Of Deposition Temperature On The optical Properties Of Iron-Doped Cadmium Stannate Thin Films Deposited By Spray Pyrolysis
(IJSTRE, 2019)
: Spray Pyrolysis Technique (SPT) was used to deposit thin films (TFs) of cadmium stannate, doped
with iron (Fe) for the first time. The precursor solutions that were used wereprepared at a concentration of
0.1M, doped ...
Similarity Transformation Analysis of Heat and Mass Transfer Effects on Steady Buoyancy Induced MHD Free Convection Flow Past an Inclined Surface
(2017)
The present work is devoted to the problem of a steady two di-
mensional hydromagnetic convective
ow of a viscous, incompressible
electrically conducting
uid past an inclined semi-in nite plate in the
presence of ...
A Critical Overview of the Kenyan Prisons System: Understanding the Challenges of Correctional Practice
(International Journal of Innovation and Scientific Research, 2014)
Kenya has been widely criticized for its on-going abuse of human rights and corruption in government
administration. Moreover, the prison system in Kenya has been termed to be dilapidated since they were adopted from ...
Mathematical analysis of tip speed ratio of a wind turbine and its effects on power coefficient
(2014)
In this paper we estimate the value of tip speed ratio of a wind turbine and evaluate its effects on power coefficient. The power coefficient, Cp, is achieved at a particular tip speed ratio, β, which is specific to the ...
