Modeling returns and unconditional variance in risk neutral world for liquid and illiquid market.
(University of Nairobi, 2015)This article seeks to model daily asset returns using log-ARCH-Lévy type model which is expected to reproduce most of the stylized features of financial time series data (such as volatility clustering, leptokurtic nature ... -
Modeling the 2-D seismic velocity structure across the Kenya rift
(Department of Earth and Atmospheric Sciences, Purdue University, USADepartment of Geological Sciences, University of Texas at El Paso, USADepartment of Physics, University of Nairobi, Kenya, 1994)A 460-km-long seismic refraction/wide-angle reflection profile across the East African rift in Kenya has been interpreted using a travel-time inversion method to calculate a two-dimensional crustal and uppermost mantle ... -
Modeling the Interruption of the Transmission of Soil-Transmitted Helminths Infections in Kenya: Modeling Deworming, Water, and Sanitation Impacts
(University of Nairobi, 2021)Kenya, just like other countries with endemic soil-transmitted helminths (STH), has conducted regular mass drug administration (MDA) program for the last 5 years among school aged children as a way to reduce STH infections ... -
Modeling trust in social networks
(University of Nairobi, 2016)We rely on trust in our day to day interactions and activities with each other. It is not easy to estimate it but we offer a simple and powerful method for estimating trust levels of agents in a social network using data ... -
Modeling water balance components in relation to field layout in lowland paddy fields. I. Model development
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 1996-04)In this study, a water balance model applicable to lowland paddy fields was developed. The model inputs consist of irrigation supply, climatic data, soil parameters and layout dimensions. The model is formulated to simulate ... -
Modeling water balance components in relation to field layout in lowland paddy fields. II: Model application
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 1996-04)In a companion paper, the development of a water balance model to predict the changes in water balance components in relation to field layout in lowland paddy fields was outlined. In this study, the model was applied to a ... -
Modelling an Institutional Mobile Learning Readiness Analyser
(University of Nairobi, 2015)Due to the affordability, ease of use and availability of mobile devices, many people in Africa and developing countries have acquired at least a mobile device. The penetration of mobile devices places many learning ... -
Modelling Dispersion Using Finite Mixture Of PoissoN
(University of NairobiSchool of Mathematics University of Nairobi, 2011)The negative binomial distribution is a versatile distribution in describing dispersion. The negative binomial parameter k is considered as a dispersion parameter. The aim of this paper is to demonstrate that filnite mixture ... -
Modelling The Dynamics Of Migrations For Large Herbivore Populations In The Amboseli National Park, Kenya
(Universty of Nairobi, 2013-04)The spread of human activity, settlement and land fragmentation threatens the migrations of large migratory ungulates in Africa. Modelling the migrations gives conservationists a tool for building scenarios of the threats ... -
Modelling the vertical distribution of insects
(University of Nairobi.School of Mathematics., 1996)The Weibull distribution has been used to model the vertical distribution of insects under a number of activities: natural flight without any artificial stimulus, resting behaviour, and response to trapping involving colour ... -

Molecular characterization and identification of biocontrol isolates of Trichoderma harzianum from Embu district, Kenya
(School of Biological Sciences, 2011)Species in the genus Trichoderma are important commercial source of several enzymes, biofungicides and growth promoters. The most common biological control agents of the genus are strains of T. harzianum, T .viride and T. ... -
Molecular detection and characterization of potentially new Babesia and Theileria species/variants in wild felids from Kenya
(University of NairobiDepartment of Biochemistry, 2012-10)Piroplasms frequently infect domestic and wild carnivores. At present, there is limited information on the occurrence and molecular identity of these tick-borne parasites in wild felids in Kenya. In 2009, a pair of captive ... -
Molecular Epidemiology of Plasmodium falciparum Malaria Outbreak, Tumbes, Peru, 2010–2012
(2015)During 2010–2012, an outbreak of 210 cases of malaria occurred in Tumbes, in the northern coast of Peru, where no Plasmodium falciparum malaria case had been reported since 2006. To identify the source of the parasite ... -
