(University of Nairobi, 2017)
The installation of Photovoltaic (PV) solar systems in institutions as well as homesteads in the rural areas in Kenya is increasing at a high rate; and so is the need for the stake holders to make sure the ...
On Local Linear Regression Estimation of Finite Population Totals in Model Based Surveys
(University of Nairobi, 2018)
In this paper, nonparametric regression is employed which provides an estimation of unknown finite population totals. A robust estimator of finite population totals in model based inference is constructed using the procedure ...
Electrophoretic Deposition of Titanium Dioxide Thin Films for Photocatalytic Water Purification Systems
(University of Nairobi, 2017)
In this study, electrophoretic deposition (EPD) technique was used to deposit titanium dioxide (TiO2) thin films on conducting glass substrates for application in water purification from organic contaminants. Phenol was ...
Raman Crystallinity and Hall Effect Studies of Microcrystalline Silicon Seed Layers
(University of Nairobi, 2017)
Aluminium induced crystallization (AIC) was used to crystallize sputtered amorphous silicon thin films on aluminium-coated glass substrates at annealing temperatures ranging from 250-520°C in vacuum. Crystalline volume ...
Containment Studies of Transgenic Mosquitoes in Disease Endemic Countries: The Broad Concept of Facilities Readiness
(University of Nairobi, 2018)
Genetic strategies for large scale pest or vector control using modified insects are not yet operational in Africa, and currently rely on import of the modified strains to begin preliminary, contained studies. Early ...
