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 ...

The present study sought to establish the influence of parenting styles on adolescent academic achievement in day secondary schools in North Rachuonyo Sub-County, Kenya. Baumrind’s theory of parenting style informed the ...
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 ...

(Mediterranean Journal of Social Sciences, 2013-09)
The aim of this study was to investigate the effect of using concept mapping strategy in teaching physics on the attitude towards physics. Participants were (46) first year students from two classes enrolled to the course ...
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 ...
Influence of gender on job satisfaction of secondary school teachers in Kenya
(Scientific & Academic Publishing, 2017)
This study investigated the influence of gender on job satisfaction of secondary school teachers in Kisii Central Sub-County, Kenya. Maslow’s hierarchy of needs and Herzberg’s two factor theories formed the basis for the ...
