HYDRODYNAMIC ANALYSIS OF A FIXED INCLINE SLIDER BEARING
(2016-05-23)
In the present day technological scenario, machines rotating at high speeds and carrying heavy rotor loads are used. As a result, fixed incline slider bearings are used. They are designed for high axial loads. When a bearing ...
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 ...
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.%, ...
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 ...

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 ...
On a complex spacetime frame: new foundation for physics and mathematics
(Research gate, 2016)
This paper provides a derivation of a unit vector specifying the temporal axis of four-dimensional space-time frame as an imaginary axis in
the direction of light or general wave propagation. The basic elements
of the ...
