Environmental implications of high metal content in soils of a titanium mining zone in Kenya.
(University of Nairobi, 2016)Mining activities contribute to an increase of specific metal contaminants in soils. This may adversely affect plant life and consequently impact on animal and human health. The objective of this study was to obtain the ... -
Secure signal and space alamouti scheme
(University of Nairobi, 2016)A method is proposed that secures the conventional Alamouti space-time block code against an eavesdropper by use of both signal and space rotations. Signal rotation is realized by applying a random rotation angle to the ... -
Performance of ma-spatial modulation: information theoretic criteria over correlated Rayleigh fading channels
(University of Nairobi, 2016)In this study, symbol error probability of tra nsmitted modulation signals for a single-input – multiple-output system is used to derive overall average bit error probab ility (ABEP) of multiple active-spatial modulation ... -
Effectiveness of aerobic microbials in breaking down of hydrocarbons in effluent discharges from petroleum service stations
(University of Nairobi, 2016) -
Determining break down of hydrocarbons in effluent discharges from petroleum service stations
(University of Nairobi, 2015)The study sought to find out how hydrocarbons are broken down in effluent from petrol stations by the existing bacteria in the effluent. This was established by collecting samples from two petrol station interceptors and ... -
Banana pith as a natural coagulant for polluted river water
(University of Nairobi, 2016)Poorly managed urban runoff and wastewater collection systems contaminate surface water, making it necessary to treat the water before use in households. Coagulation and flocculation are essential components of the treatment ... -
Designing for informal contexts: a case study of Enkanini sanitation intervention
(University of Nairobi, 2016)Increasing social agency in the design profession corresponds to the call for greater participation of science in solving complex social problems. We analyse the complex problem of informal urban sanitation in the Enkanini ... -
Mapping stakeholder positions in the Kenyan land reform process
(University of Nairobi, 2016)The debate on land reform in sub-Saharan Africa has moved from the purpose and direction of reforms to the reasons why proposed reforms are not being implemented. The literature shows that one of the reasons for failure ... -
Cassava chips quality as influenced by cultivar, blanching time and slice thickness
(2016)Cassava forms part of diets in Kenya with both the roots and leaves being consumed as food. The short shelf-life of 72 hours and cyanogenic glucosides limit the extent of utilization. Currently, fried cassava chips and ... -
Inter-agency collaboration for fire disaster management in Nairobi City
(University of Nairobi, 2016-06)The County Government of Nairobi faces a myriad of capacity challenges that have impeded fire disaster management in the City. This is further compounded by the lack of a comprehensive legal and institutional framework for ... -
Measuring exposure levels of inhalable airborne particles (PM2.5) in two socially deprived areas of Nairobi, Kenya
(University of Nairobi, 2016-07)Introduction Ambient air pollution is a growing global health concern tightly connected to the rapid global urbanization. Health impacts from outdoor air pollution exposure amounts to high burdens of deaths and disease ... -
Spatial Analysis of Distribution and Socio-economic Impacts of Immigration: Case Study of Nairobi, Kenya
(2015)Increasing globalization trends have made migration a key element in national and international deliberations worldwide. Mapping of immigrant issues has therefore gained prominence in many parts of the world. In Kenya ... -
Computational Approach to Investigation of Crack Behaviour under Vehicular Loading of A Typical Concrete Pavement (A Case Study of Mbagathi Road in Nairobi)
(2015)Nairobi County has nearly 100% road network as bituminous roads and only 4km road network (Mbagathi Road) is concrete road. This road was a pilot project that was implemented by Kenyan Government between the years 2005 ... -
Water, sanitation conditions and implications for child survival in Kenya: A review of statistical evidence from the 1999 census of population
(2016)Water supply and sanitation are important requisites for basic human needs and primary health care. Their inadequate provision has far reaching economic and humanitarian consequences. In Kenya this is well expressed in ... -
Advanced manufacturing technology adoption in manufacturing companies in Kenya
(2015)Over the past few decades, manufacturing has evolved from a more labor-intensive set of mechanical processes to a sophisticated set of information based technology processes. With the existence of various advanced ... -
An Optimal Eigenvalue Based Spectrum Sensing Algorithm for Cognitive Radio
(2015)Spectrum is a scarce resource, and licensed spectrum is intended to be used only by the spectrum owners. Various measurements of spectrum utilization have shown unused resources in frequency, time and space. Cognitive ... -
A review of techniques in optimal sizing of hybrid renewable energy systems
(2015)This paper presents a review of techniques usedin recent published works on optimal sizing of hybrid renewable energy sources. Hybridization of renewable energy sources is an emergent promising trend born out of the need ... -
Combined Real and Reactive Power Economic Dispatch using Multi-Objective Reinforced Learning with Optimized Losses
(2015)Most of the economic dispatch (ED) works so far deal with real power dispatch only. With the integration of renewable energy into the grid, reactive power dispatch cannot be ignored any longer due to its importance in ... -
Distributed transmit-power control in cognitive radio networks using a hybrid-adaptive game-theoretic technique
(2015)This paper studies game-theoretic distributed transmit-power control in a cognitive radio network. It presents a hybrid-adaptive algorithm that interfaces Iterative Water-Filling with two learning algorithms: the Hedging ...
