Mathematical modelling of HIV infection
(IJMA, 2013)
We formulate a deterministic mathematical model for the HIV/AIDS.
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 ...
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 ...
Determining the attitude of undergraduate students towards physics through concept mapping
(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 ...
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’ ...
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 ...
Symmetry group approach to the solution of generalized burgers equation: Ut + UUx = λUxx
(2013)
Symmetry of a system of differential equations is a transformation
that maps any solution to another solution of the system. In Lie’s
framework such transformations are groups that depend on continuous
parameters and ...
Effects of outliers on estimation of finite population totals
(2013-06)
In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ...
