Deterministic mathematical model for fish harvesting
(INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY, 2015)
Differential equations have been used to create mathematical models of real world systems in which rates of change are involved, for example in the study of how population grows or shrinks. One of the earliest models by ...
Socio-economic factors influencing the spread of drinking water diseases in rural Africa: case study of Bondo sub-county, Kenya
(IWA Publishing, 2015)
Socio-economic and medical information on Bondo sub-county community was studied to help establish the relationship between the water quality challenges, community health and water rights conditions. Health challenges have ...
Drug and Substance Use and Its Predictors among the Youth in Nyamira Sub County, Nyamira
(www.strategicjournals.com, 2018-11-11)
Substance and drug use is one of the emerging public health problems among the youth in Kenya. Moreover, it is associated with a myriad of medical effects including psychiatric problems, organ failures in addition to ...
Nonzero Lie Brackets of Third Order Nonlinear Ordinary Differential Equation
(ResearchGate, 2018-06)
Lie symmetry analysis of Ordinary Differential Equation can be used to obtain exact solution of the equation of the form F (x, y, y’ y’’ y’’’) = 0. In this paper we use Lie Symmetry analysis approach to obtain the nonzero ...
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 ...
Malaria vector species distribution and seasonal population dynamics across varied ecological zones in Baringo County, Kenya
(Journal of Mosquito Research, 2017)
Vector populations fluctuate on a seasonal basis annually. Knowledge on seasonal abundance and distribution of vector species at the local level would improve vector control programmes and contribute to malaria prevention. ...
On necessary and sufficient conditions for rationality of operator norm bounds in measure spaces
(2016-11)
Norm bounds are useful properties of operators with interesting applications in operator algebras and quantum mechanics. Rationality of these norm bounds is very important in the study of operators in measure spaces. As a ...
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 ...
Attitudes of students and teachers towards use of computer technology in Geography education
(2010)
The ability to display simulated environments through the computer may make it a stimulating instructional tool for illuminating abstract concepts in Geography. In Kenya, there is persistent lack of resources to improve ...
