Generalized relativistic dynamics in a non-inertial reference frame
(Springer-Verlag, 2010)
Generalized relativistic field equations have been derived for dynamics in a non-inertial reference frame interpreted as a Finsler space where events are specified by both spacetime coordinates and corresponding velocities ...
A Direct Calculation of First-Order Wave Function of Helium
(IOP Publishing, 2010)
We develop a simple analytic calculation for the first order wave function of helium in a model in which nuclear charge screening is caused by repulsive coulomb interaction. The perturbation term, first-order correlation ...
Symmetry Dependent Analytical Pseudopotential for Helium Atom
(2019-11-11)
Electron-electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron
systems are the simplest many-body systems in nature. The Schr¨odinger ...
Analytical Absorption Cross-Section for Photon by a Hydrogen 2s Atom
(IOP Publishing, 2011-04)
We calculate the absorption cross-section for photon by a hydrogen 2s atom using the quantum-classical approximation for the total photo cross-section of many electron atoms. With the application of the first-order term ...
Quiet Time Correlation Between Geomagnetic Field Variations and the Dynamics of the East African Equatorial Ionosphere
(Science Publishing Group, 2017)
The equatorial ionosphere is highly dynamic and consequently poses serious threats to communication and
navigation systems. As a result, proper understanding of ionospheric dynamics is important. The present paper presents ...
Variability of VTEC Gradient and TEC Rate Index Over Kisumu, Kenya During Selected Quiet and Storm Days of 2013 and 2014
(Science Publishing Group, 2019)
Vertical Total electron content (VTEC) gradient or rate of change of TEC (ROT) and total electron content (TEC)
rate index or rate of change of TEC index (ROTI) can directly be estimated from receiver independent exchange ...
Total electron content and scintillations over Maseno, Kenya, during high solar activity year
(Springer International Publishing, 2019)
Proper characterization of total electron content (TEC) and scintillation is very important to global positioning system (GPS) users in communication, navigation, ionospheric or atmospheric studies. Quiet time variation ...
Quiet Time Geomagnetic Field Variations in the Equatorial East African Region During the Inclining Phase of Solar Cycle 24
(Science Publishing Group, 2014)
In the present paper, geomagnetic field data obtained from magnetometer measurements at two ground based
stations have been used to study solar activity dependence of the solar quiet variations. The study has focused on ...
An investigation of MHD Flows of Nanofluid over an oscillating surface with Joule Heating
(International Scientific Press, 2017)
The present study aims at investigating unsteady hydromagnetic flow of viscous
incompressible, conducting nanofluid over an infinite oscillating surface with
Joule heating. The governing equations involved are transformed ...
A numerical thermal growth model for prediction of microalgae production in photobioreactors
(AIP Publishing, 2016-03)
A thermal growth model for microalgae that are not heavier than water with the consideration of heat transfer and growth-temperature dependence in photobioreactor (PBR) is developed. The microalgae growth performance is ...
