Mathematical modelling of HIV infection
(IJMA, 2013)
We formulate a deterministic mathematical model for the HIV/AIDS.
Finite difference solution of (1+1) sinegordon equation: A mathematical model for the rigid pendula attached to a stretched wire
(The SIJ Transactions on Computer Science Engineering & its Applications (CSEA), 2015-04)
The nonlinear (1+1) Sine-Gordon equation that governs the vibrations of the rigid pendula attached to a stretched wire is solved. The equation is discretized and solved by Finite Difference Method with specific initial and ...
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(IJESM, 2013-03)
In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ...
Construction of nominal yield curve for Nairobi securities exchange: an improvement on monotone preserving r(t)t interpolation method
(Scientific Research Publishing Inc., 2015-11)
There is no agreed-upon method used to construct yield curves at the Nairobi Securities Exchange. The existing practice is that each financial company uses in-house methods to construct the yield curves for their pricing ...
Forensic estimation of time of death: A mathematical model
(International Journal of Management, IT and Engineering, 2013-07)
In this paper we establish the exact time of death of a murdered person. This leads to an ordinary differential equation whose solution has been analyzed to provide the approximate time of death. Forensic expert will try ...
Incremental modernization of statistics teaching and curriculum at Maseno University, Kenya
(ISI/IASE], 2010)
Modernisation of statistics teaching is a continual problem the world over. The advances in statistical methods and tools along with the growing demand of applied practitioners creates a dual need of people with the ...
Two dimensional mathematical models for convective-dispersive flow of pesticides in porous media
(International Journal of Engineering Science and Computing, 2016)
The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over the years. Use of pesticides has resulted in ...
Functions of multi-pendula system spatial motion
(Published by The Standard International Journals, 2017)
A study has been done using generalized coordinates system with the application of the Lagrangian formalism for n mass units linearly connected to move in space. Lagrangian equations have been developed and used throughout ...
Analytic solution of a nonlinear black-scholes partial differential equation
(Academic Publications, 5/10/2010)
We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of a feedback effect. This is an illiquid market effect arising from transaction costs. An analytic solution to the nonlinear ...
Teachers` gender and primary school pupils` achievement in mathematics in Kenya
(Journal of Education and Practice, 2013)
This descriptive causal comparative study examined the relationship between teacher’s gender and in primary schools pupils’ performance in mathematics in Kenya. The study objective was to investigate the effect of teachers’ ...
