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 ...
Analysis of Loss Ratios Using a Mixed Linear Model
(University of Nairobi, 2008)
Loss ratios have been employed by a broad range of users for diverse purposes. Insurance companies, regulators, investors, rating agencies, investment analysts, lenders and others have used the loss ratio for their particular ...
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 ...
Mathematical modelling of wind turbine in a wind energy conversion system: Power coefficient analysis
(2012-01)
The world is increasingly going green in its energy use. Wind power is a green renewable source of energy that can compete effectively with fossil fuel as a generator of power in the electricity market. For this effective ...
Numerical solutions of the Burgers’ system in two dimensions under varied initial and boundary conditions
(2012)
In this paper, we generate varied sets of exact initial and Dirichlet boundary conditions for the 2-D Burgers’ equations from general analytical solutions via Hopf-Cole transformation and separation of variables. These ...
Steady MHD poiseuille flow between two infinite parallel porous plates in an inclined magnetic field
(2012)
In this paper, we examine the motion of a two dimensional steady flow of a viscous, electrically conducting, incompressible fluid flowing between two infinite parallel porous plates under the influence of transverse magnetic ...
Mathematical model of variable speed pitch regulated turbine in a wind energy conversion system
(2014)
Pitch control of wind turbine in a wind energy conversion system involves the change of the rotor blade pitch angle along the rotor axis. Most compa-nies are faced with the challenge of maintaining a steady and optimal ...
