Micronutrients in selected food crops in Muguga, Kenya
(University of Nairobi, 2014)Micronutrients are essential for growth of plants and although they are required in small quantities, inadequate supply of one or more of these results in reduced yields and quality of crop products. Micronutrients are ... -
Deflection characteristics for flexible road and aiport pavements in Kenya
(2004)As traffic traverses a flexible pavement the axle loads induce a downward deflection of the pavement surface. The pavement however, bounces back as soon as the load passes a section. This downward deflection is measured ... -
Coping strategies adopted by public universities in Kenya in response to environmental changes
(University of Nairobi, 2014)This study was undertaken to establish strategies adopted by public universities in Kenya in response to changes in the environment. The study design was descriptive and utilized a cross-sectional survey of all the public ... -
Incompressible smoothed particle hydrodynamics modeling of thermal convection
(2013)An incompressible smoothed particle hydrodynamics (ISPH) method based on the incremental pressure projection method is developed in this study. The Rayleigh-Bénard convection in a square enclosure is used as a validation ... -
Natural gamma radiation levels, indoor and water 222 RN Concentrations in soil division of Kerio valley, kenya
(University of Nairobi, 2001)Human beings are constantly exposed to natural radioactivity. This radiation is mainly from natural gamma rays and radon and its decay products. The gamma rays are as a result of the decay of primordial nuclides and their ... -
Reducing real and reactive power losses in the distribution system by DFIG placement and sizing using ordinary PSO and HGPSO : a comparison
(University of Nairobi, 2012)Due to the increased importance of DFIGs in optimization of real and reactive power losses and the maintenance of voltage profile, the general methods of DG placement and sizing in the existing literature cannot be of ... -
Biosorption of Zn (II) ions from aqueous solutions by water hyacinth (Eichhornia crasippes): Equilibrium and Kinetic studies
(2014)The biosorption characteristics of Zn (II) ions were investigated. Experimental parameters affecting the biosorption process such as pH, contact time, biomass dosage, initial metal ion concentration, and temperature were ... -
Modelling the potential of rainwater harvesting in western Kenya using remote sensing and GIS techniques
(University of Nairobi, 2014-11)Water scarcity is among the many problems faced today by many countries in the world, especially African countries. The Kakamega area in western Kenya is known for plenty of rainfall (around 2000 mm annually), however, ... -
Optimizing the location of base transceiver stations in mobile communication network planning: case study of the Nairobi central business district, Kenya
(University of Nairobi, 2014)Optimal signal coverage has always been a fundamental issue for cellular network operators. Other issues related to capacity, quality of service and cost efficiency are also rapidly gaining prominence. In order to determine ... -
First in first out (FIFO) and priority packet scheduling based on type of service (TOS)
(University of Nairobi, 2014)Mobile Ad Hoc Networks (MANETs) require prudent res ource allocations especially in scheduling mechanis ms that manage buffering of packets during waiting tim e. Various scheduling algorithms may be implemented to govern ... -
