Energy Resources in East Africa
(Springer, Cham, 2015)
When talking about East Africa, traditionally this refers to the states of Kenya, Uganda and Tanzania with a combined population of over 120 million people in 2014. The three countries have a long history of association ...
First Order Expectation Values of Electron Correlation Operators for Two-Electron Atoms
(SPG, 2015)
Simple analytic first-order wave functions corresponding to two-electron atoms electron correlation operators are
obtained by reduction of the Rayleigh-Schrödinger first order perturbation equation to that of one-electron ...
Mathematical model of pneumonia and HIV/AIDS coinfection in the presence of protection
(2015)
In this paper, a deterministic co-infection model incorporating protection from infection for both pneumonia infection and HIV/AIDS is considered. The model is shown to be positively invariant as well as bounded. Specifically ...
Finite Difference Analysis of 2-Dimensional Acoustic Wave with a Signal Function
(2015-12-09)
This paper describes progress on a two dimensional numerical simulation of acoustic wave propagation that has been developed to visualize the propagation of acoustic wave fronts and to provide time-domain signal. In this ...
Ab initio study of the structural, vibrational and thermal properties of Ge2Sb2Te5
(Imperial College Press, 2015-06-12)
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 ...
Enhancing light absorption and lifetime stability of organic solar cells using pentacene encapsulation
(SA Institute of Physics, 2015)
. In the present work we compare the performance of a pristine P3HT:PCBM
based bulk heterojunction solar cell with a device incorporated with pentacene encapsulated
Ag nanoparticles. Encapsulation has been achieved through ...
On the steady MHD couette flow between two infinite parallel plates in an uniform transverse magnetic field
(2015)
In this paper we consider laminar viscous incompressible fluid between two
infinite parallel plates when the upper plate is moving with constant velocity Uo
and the lower plate is held stationary under the influence of ...
Progressively accurate WKB approximations through factorization and successive boost transformations
(Research gate, 2015)
This paper develops a procedure for obtaining progressively improving approximate solutions
of the WKB (semiclassical ) model of the stationary Schroedinger equation through factorization and successive boost transformations ...
Composite Hermite and Anti-Hermite Polynomials
(Scientific Research Publishing, 2015)
The Weber-Hermite differential equation, obtained as the dimensionless form of the stationary
Schroedinger equation for a linear harmonic oscillator in quantum mechanics, has been expressed
in a generalized form through ...
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 ...
