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’ ...
Operators with slowly growing resolvents towards the spectrum
(Academic Publications, 1/13/2009)
A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies
(z −H)−1
≤ c hziα |=z|β ∀ z 6∈ R (0.1) for some α , β ≥ 0; c > 0, is said to be of (α, β)−type R . If instead of (0.1) ...
Extraction of zero coupon yield curve for Nairobi securities exchange: finding the best parametric model for East African securities markets
(Science Signpost Publishing, 2015)
We seek to construct a zero coupon yield curve (ZCYC) for Nairobi Securities Exchange (NSE). The objective of this paper is to construct a ZCYC that is differentiable at all points and at the same time, produces continuous ...

Modeling co-infection of paediatric Malaria and Pneumonia
(Int. Journal of Math. Analysis, 2013)
Malaria and persistent childhood diseases are a major threat to child survival in the developing world. In this paper, we develop and analyse a mathematical model for paediatric malaria and pneumonia co-infection. We ...
Modeling of liver cancer risk factors and dynamics at community level
(Hikari, 2017)
Hepatocellular carcinoma (HCC) is a malignant cancer of the liver arising from uncontrolled multiplication of the abnormal liver cells. It is an ignored public health condition where patients come late to the hospital at ...
