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

Predicting E-Procurement Utilization in Independent Commissions in Kenya
(2016)E-procurement has recently been introduced in the Kenyan public sector due to the many practical advantages it brings. Usage of the system is still at a very nascent stage. This paper sought to predict e-procurement ... -
Evaluation of Intelligent Grouping Based on Learners’ Collaboration Competence Level in Online Collaborative Learning Environment
(2016)In this paper we explore the impact of an intelligent grouping algorithm based on learners’ collaborative competency when compared with (a) instructor based Grade Point Average (GPA) method level and (b) random method, ... -
Optimized Routing and Component Placement to Improve the Continuity And Uniformity of the PCBPIFL Antenna’s Co-Planar Ground Plane to Achieve an Overall Improved Antenna Performance
(2015)A ground plane forms the other half for quarter wave PCB antennas. Integration of these type of antennas with other components within the same PCB of a mobile device compromise the uniformity and continuity of the ground ... -
A Hybrid Algorithm for Detecting Web Based Applications Vulnerabilities
(2016)Web vulnerability scanners (WVS) are tools for discovering vulnerabilities in a web application. However, they are not 100% accurate. In this paper we develop a hybrid algorithm for detecting web based applications ... -
A Case for Judicial Data Warehousing and Data Mining in Kenya
(2016)This aim of this study was to demonstrate how the Extract, Transform and Load (ETL) process can be utilized to assist the Kenyan Judiciary address challenges of data integration in its operational systems and hence provide ... -
Experimental evaluation of inactivated and live attenuated vaccines against Mycoplasma mycoides subsp. mycoides
(2016)The current control method for contagious bovine pleuropneumonia (CBPP) in Africa is vaccination with a live, attenuated strain of Mycoplasma mycoides subsp. mycoides (Mmm). However, this method is not very efficient and ... -
Interactions among vegetable-infesting aphids, the fungal pathogen Metarhizium anisopliae (Ascomycota: Hypocreales) and the predatory coccinellid Cheilomenes lunata (Coleoptera: Coccinellidae)
(2016)Entomopathogenic fungi are among biocontrol agents being considered for the control of aphids on a variety of crops. Predatory coccinellids, although generalist, are also among important natural enemies that must be conserved ... -

Sclerotia Formation and Toxin Production in Large Sclerotial Aspergillus flavus Isolates from Kenya
(2016)We studied the relationship between sclerotia formation and aflatoxin production by Aspergillusflavus strains isolated from maize kernels from Nandi County. Isolates recovered from maize kernels were tested for their ability ... -
Eave Screening and Push-Pull Tactics to Reduce House Entry by Vectors of Malaria
(2016)Long-lasting insecticidal nets and indoor residual spraying have contributed to a decline in malaria over the last decade, but progress is threatened by the development of physiological and behavioral resistance of mosquitoes ... -
Spatially variable risk factors for malaria in a geographically heterogeneous landscape, western Kenya: an explorative study
(2016)Background Large reductions in malaria transmission and mortality have been achieved over the last decade, and this has mainly been attributed to the scale-up of long-lasting insecticidal bed nets and indoor residual ... -
On the effects of random forces in non uniformly distributed dynamical system
(University of Nairobi, 2010)Interaction of a dynamical system with stochastic source R(t) is studied using parabolic type equation on a circle of length 2L.Greens function for the system is constructed and it is shown that almost all the correlation ... -
