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 ... -
Evaluation of the Implementation of the e-Citizen in Kenya
(2016)Information Communication Technology (ICT) can make a valuable contribution towards the operations of and the services offered to citizens by a government. While the benefits of e-Government initiatives and projects in ... -
Cloud Computing Adoption in Insurance Companies 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 ... -
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 ... -
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 ... -
Molecular Investigation into a Malaria Outbreak in Cusco, Peru: Plasmodium falciparum BV1 Lineage is Linked to a Second Outbreak in Recent Times
(2016)In November 2013, a Plasmodium falciparum malaria outbreak of 11 cases occurred in Cusco, southern Peru, where falciparum malaria had not been reported since 1946. Although initial microscopic diagnosis reported only ... -
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 ... -
Optical Characterization Of TiO2-bound (CuFeMnO4) Absorber Paint For Solar Thermal Applications
(University of Nairobi, 2016)Abstract A composite thin film consisting of TiO 2 (binder), uniformly mixed CuFeMnO 4 paint (solar absorber) was coated on textured aluminum sheets by dip coating. The film’s elemental analysis ... -
Quality Indicator framework for assessing DEel programs in Kenya: A Technological and Educational functional parameters approach
(University of Nairobi, 2016-04)The demand for university education has continued to grow and hence there has been a phenomenal expansion in enrolments that is not matching with the expansion of facilities. Several policy reports commissioned by the ... -

Serotype and genetic diversity of human rhinovirus strains that circulated in Kenya in 2008
(2016)Background Human rhinoviruses (HRVs) are a well-established cause of the common cold and recent studies indicated that they may be associated with severe acute respiratory illnesses (SARIs) like pneumonia, asthma, and ... -
Structural and Optical Characterization of Tin Oxide Codoped with Aluminum and Sulphur
(2015)Thin films of Tin oxide co-doped with 28at%Aluminum and varied concentration of Sulphur were prepared on 1mm thick, 1 × 1 cm2 glass substrates at 470℃ by spray pyrolysis technique. Films were produced from 2.0 M solution ... -
A note on quasi-similarity of operators in Hilbert spaces
(2015)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi- affinity from one Hilbert Space H to K. Some results on quasi- affinities are also ... -
Effects of antioxidants on oxidation and storage stability of Croton megalocarpus biodiesel
(Springer, 2016)The effects of antioxidants and storage on oxidation stability of croton biodiesel and its blends with petro-diesel were determined using PetroOxy equipment. The biodiesel and blends were kept in Pyrex reagent bottles and ...
