Elementary partial differential equations
(Lambert, 2013-06-01)
The importance of partial differential equations cannot be gainsaid. They are used in science and engineering. Many natural phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow etc occurring in science ...
Some new features of photon statistics in a fully quantized parametric amplification process
(Scientific Research Publishing, 2014)
An exact quantum treatment reveals that signal and idler photon number operators are not wellbehaved dynamical operators for studying photon statistics in parametric amplification/downconversion processes. Contrary to ...
General analytical solution for the one dimensional regular Cauchy problem of Euler-Poisson-Darboux equation
(Hikari Ltd, 2017)
A general analytical solution to the one dimensional regular Cauchy
problem of Euler-Poisson-Darboux (EPD) equation has been investigated. The one dimensional EPD which is a Partial Differential Equation (PDE) with initial ...
Stability Investigation in the Optical Properties of Thermally Evaporated Ge5Se95-x Znx Thin Films
(University of Nairobi, Kenya, 2015)
Selenium-based chalcogenides are useful in telecommunication devices like infrared optics and threshold switching
devices. The investigated system of Ge5Se95-xZnx (0.0 ≤ x ≤ 4 at.%) has been prepared from high purity ...
Structural and spectroscopic analysis of ex-situ annealed RF sputtered aluminium doped zinc oxide thin films
(AIP Publishing LLC, 2017)
Aluminium doped zinc oxide thin films are prepared by Radio Frequency magnetron sputtering in
pure argon atmosphere at 100 W. The structural results reveal good film adhesion on a silicon
substrate (001). The thin films ...
Fundamental quantum noise in a fully quantized degenerate parametric amplification process
(Research gate, 2016)
An exact analytical solution of the time-dependent Schroedinger equation for a fully quantized
degenerate parametric amplification process generated by quantized multi-mode pump photons
provides a quantized multi-photon ...
Effects of Conduction and Variable Properties On a Two Dimensional Conjugate Heat Transfer of a Nanofluid in a Microchannel
(International Scientific Press, 2013-10-01)
In this paper we analyze the effects of conduction and variable properties on a two dimensional conjugate heat transfer of a nanofluid containing a mixture of two fluids namely, Aluminium oxide (Al2O3) and water. Nanoparticles ...
A note on momentum and energy conservation in dynamics under arbitrary forces in classical Newtonian and relativistic mechanics
(Research gate, 2018)
In teaching mechanics course to first year undergraduate students, I have come across a simple, but very important, gap in the formulation of the principle of conservation of momentum and energy in the dynamics of a body ...
Near-Exact Non-relativistic Energies for Many-Electron Atoms
(2017-12)
Electron-electron interactions and correlations form the basis of difficulties encountered in the
theoretical solution of problems dealing with multi-electron systems. Accurate treatment of the
electron-electron problem ...
ON SINGULAR CAUCHY PROBLEM OF EULER-POISSON DARBOUX EQUATION
(2012)
We solve the singular Cauchy problem of Euler-Poisson-Darboux equation. The Riemann function, a solution corresponding to the adjoint equation is calculated and it enables us to evaluate any solution at a point by the ...
