(2015)Severe acute malnutrition is a widely prevalent problem in developing countries and a major cause of morbidity and mortality. Traditionally, children with severe acute malnutrition were rehabilitated within inpatient ... -
Adherence of healthcare practitioners to the adolescent reproductive health and development policy at The Garissa Provincial General Hospital, Kenya
(2015)Background: Kenya’s policies relating to population, family planning (FP) and reproductive health (RH) receive weak/fluctuating levels of adherence. The Adolescent Reproductive Health and Development (ARH&D) policy gives ... -
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 ... -
Extension Officers' Requirements in an artificial Intelligent System for Diagnosis of Maize Disease, Kenya
(University of Nairobi, 2015)A study was conducted to determine the most frequently used agricultural diagnostic information source by extension officers, the content of information which both the extension officer would like to receive for full ... -
Comparative analysis of ear-hole closure identifies epimorphic regeneration as a discrete trait in mammals
(2016)Why mammals have poor regenerative ability has remained a long-standing question in biology. In regenerating vertebrates, injury can induce a process known as epimorphic regeneration to replace damaged structures. ... -
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 ... -
Relational patterns of urbanisation and economic growth in sub-Saharan Africa
(2016)Scholars of economic development have always hinted that the urbanisation process in the developing world does not follow the historical patterns discerned in the developed world where a strong relationship between a ... -
Common mental disorder in Nyanza province, Kenya in 2013 and its associated risk factors –an assessment of change since 2004, using a repeat household survey in a demographic surveillance site
(2015)Background Repeat household surveys are useful to assess change in prevalence over time, but there have been no repeat surveys of common mental disorder (CMD) in Kenya, or indeed sub-Saharan Africa. Therefore a repeat ... -
The effect of general elections on stock returns at the Nairobi securities exchange
(2015)The performance of the financial markets is significantly impacted by the political environment during eneral ellections. This paper focussed on the effect of general ellections on the stock retuns at the Nairobi ... -
Optimal error analysis of receive diversity schemes on arbitrarily correlated Rayleigh fading channels
(2016)A simple optimal error analysis of multiple-branch equal gain combining (EGC) and selection combining (SC) in the presence of arbitrarily correlated Rayleigh fading channels is presented. It is shown that the error rates ... -
The Effect of the Operational Parameters on the Draft Requirement of Ripping in a Sandy Clay Soil
(2016)This study set out to investigate the effect of operational parameters (i.e. ripping depth and operational speed) during a ripping operation on the draft requirement during ripping in a sandy-clay soil. Field experiments, ... -
Retrieval of aerosol optical depth over ecologically stressed East African land surfaces from top of atmosphere radiance utilizing the aerosol free vegetation index.
(2015)Traditional satellite based AOD retrieval techniques with a coarse resolution such as collection 5 hardly provides a high spatial detail suitable for accurate AOD retrieval particularly over the ecologically stressed sites ... -
On the existence of a non-relativistic hermitian time operator
(2016)The existence of a hermitian time operator is proposed in the framework of non-relativistic quantum mechanics.The Heisenberg equation of motion is shown to yield constant rate of flow of time.It is shown to yield results ... -
Comparing PSO and GA Optimizers in MLP to Predict Mobile Traffic Jam Times
(2015)Freely-usable frequency spectrum is dwindling quickly in the face of increasingly greater demand. As mobile traffic overwhelm the frequency allocated to it, some frequency bands such as for terrestrial TV are insufficiently ... -
Using a Mobile Based Web Service to Search for Missing People – A Case Study Of Kenya
(2015)Being out of touch with a loved one is concerning and not hearing from someone you care about is terrifying. Several cases of missing people have been reported for many years, where most of the searches turn out unsuccessful. ... -
The Critical Technological Factors OF E-Government in Kenya
(2015)EGovernment and innovation can provide significant opportunities to transform public administration into an instrument of sustainable development. However, the rate of failure of eGovernment projects in the developing ... -
Trust and Distrust: A Reputation Ratings Approach
(2016)Agents’ reputation ratings in a social network form a real valued matrix which is discounted with singular value decomposition (SVD) to estimate the trust and distrust levels of agents. SVD eliminates noise as future ... -
