(University of Eldoret, 2016)Motivated by the performance of reduced Titania in various important applications including photo-catalysis, photo-voltaics and CO2 reduction in hydrocarbon fuels, a systematic study of the structural properties and the ... -
Ab-initio STUDIES OF STRUCTURAL, ELECTRONIC, MAGNETIC AND OPTICAL PROPERTIES OF NICKEL OXIDE
(University of Eldoret, 2014)Nickel Oxide (NiO) has many applications in solar energy utilization, due to variations in electronic, optical and magnetic properties. However, a satisfactory description of its properties is still not available. There ... -
MODELING OF RING RESONATOR AS AN OPTICAL FILTER USING MEEP SOFTWARE
(University of Eldoret, 2016)Ring resonators are key components in modern optical networks. Their small size allows high density integration in optical photonic circuits due to the use of high index contrast. Ring resonator filters based Optical Filters ... -
MATHEMATICAL MODELLING ON THE IMPACT OF HOSPITALIZATION IN THE MANAGEMENT OF TYPHOID FEVER
(University of Eldoret, 2021)Typhoid fever disease is an infectious ailment which mostly leads to diarrhoea, headache, high fever and stomach pains. This disease is majorly caused by a bacterial infection known as Salmonella typhi. Typhoid fever has ... -
MATHEMATICAL MODELING OF FLOW OF WATER IN AN OPEN CHANNEL OF PARABOLIC CROSS-SECTION
(University of Eldoret, 2021)This study investigates open channel flows with a parabolic cross-section. The objectives of this study were to examine the effects of top width, channel slope, and energy coefficient on flow velocity. The methodology used ... -
THE EFFECT OF TWO LATERAL INFLOW CHANNELS ON MAIN CHANNEL DISCHARGE
(University of Eldoret, 2021)In this study, we examined the flow from two lateral inflow channels in a man-made open rectangular channel of an incompressible Newtonian fluid. The influence of cross-sectional area, length of two lateral inflow channels, ... -
MATHEMATICAL MODELLING OF FLOW OF FERTILIZER-WATER MIXTURE THROUGH SOIL AND ITS EFFECT ON PLANT GROWTH.
(University of Eldoret, 2021)The demand for food in developing countries is increasing daily due to population growth and dropping crop yields caused by climatic changes and acidic soils due to continuous use of inorganic fertilizers that are meant ... -
HYDROMECHANICAL SLOPE STABILITY ANALYSIS: MODELLING, MONITORING AND PREDICTION USING BP-FF ARTIFICIAL NEURAL NETWORKS
(University of Eldoret, 2021)Sloping regions of the earth’s crust have formed part of human settlements from time immemorial. However, these regions are prone to geological hazards especially mass wasting processes such as debris flows and landslips. ... -
Modulated Raman pump for integrated VCSEL-based reach enhancement and clock tone dissemination in optical communication
(Elsevier, 2019)The fast growth of data traffic in access networks calls for high speed and low-cost optical links. To extend reach for users in metro areas requires optical amplification of the signal carrying data. In this paper ... -
Integrated extended reach VCSEL interconnect with 8.5 Gbps data modulated forward Raman pump signals
(JOURNAL OF MODERN OPTICS, 2019)We experimentally present thefirst reported integrated cross-modulatedforward Raman pump, with low-cost, power-efficient VCSELs. A single-mode VCSEL is directly modulated with 8.5 Gbps data and transmitted over a 50.7 ... -
RELATIONSHIP BETWEEN NITRATES, PHOSPHATES IN WATER, IODINE LEVELS IN TABLE SALT AND GOITER OCCURENCE: A CASE STUDY OF NANDI HILLS, KENYA
(University of Eldoret, 2017)Nitrates and phosphates are among the major inorganic pollutants in the environment, primarily contributed by nitrogenous and phosphate fertilizers, organic manures, human and animal wastes, and industrial effluents through ... -
PHASE TRANSITION IN SUPERCONDUCTORS
(University of Eldoret, 2015)Superconductivity is the disappearance of DC electrical resistance in a material when it is cooled to a certain critical temperature, when a material changes from normal state to superconducting state when it is cooled ... -
