Estimation of T- period’s ahead extreme quantile autoregression function
(African Journal of Mathematics and Computer Science Research, 2010)This paper considers the estimation of extreme quantile autoregression function by using a parametric model. We combine direct estimation of quantiles in the middle region with that of extreme parts using the model and ... -
Evaluation of isometamidium levels in the serum of sheep and goats after prophylactic treatment against trypanosomosis
(Onderstepoort Journal of Veterinary Research, 2004)Evaluation of isometamidium levels in the serum of sheep and goats after prophylactic treatment against trypanosomosis. Onderstepoort Journal of Veterinary Research, 71:175–179 Isometamidium chloride has been used for the ... -
Experimental and numerical study of turbulence effect on aerodynamic performance of a small-scale vertical axis wind turbine
(2016)The suitability of vertical axis wind turbines (VAWTs) in harnessing energy within a complex wind environment has increased their renewed interest. However, there still exists a huge knowledge gap about the aerodynamic ... -
Experimental and Theoretical Characterization of Metal Complexation with Humic Acid
(2016)This study investigated the bonding of calcium and magnesium to specific sites in humic acid as a function of pH, temperature, and trace metal concentrations. Other metals were investigated but not in detail. Using a ... -
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
(AquacultureResearch, 2006)Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of di¡erent ... -
Exponentiated generalized exponential Dagum distribution
(Elsevier, 2017)In this study, the exponentiated generalized exponential Dagum distribution has been proposed and studied. This family of distribution consists of a number of sub-models such as the exponentiated generalized Dagum ... -
Exponentiated Generalized Power Series Family of Distributions
(2018)In this paper, a new family of distributions called the exponentiated generalized power series family is proposed and studied. Statistical properties such as stochastic order, quantile function, entropy, mean residual ... -
Exponentiated Generalized Transformed-Transformer Family of Distributions
(Scienpress Ltd, 2017)Recently, the development of generalized class of distributions has become an issue of interest, to both applied and theoretical statisticians, due to their wider application in different fields of studies. Thus, ... -
Extreme Value Modelling of Rainfall Using Poisson-generalized Pareto Distribution: A Case Study Tanzania
(Science Publishing Group, 2019)Extreme rainfall events have caused significant damage to agriculture, ecology and infrastructure, disruption of human activities, injury and loss of life. They have also significant social, economical and environmental ... -
Factors Influencing Smallholder Farmers’ Adaptation to Climate Variability in Kitui County, Kenya
(Juniper Publishers, 2018-02)The study was carried out to examine the factors and constraints that influence small farmers’ adaptation to climate variability in Kitui County. Descriptive survey design was used. Two villages, Kaveta and Mikuyuni, were ... -
Financial Literacy and Retirement Planning in the Informal Sector in Kenya
(2014)Old age dependency has become a major issue of concern to governments today. This is because a large number of retirees lack any form of regular income to sustain them in retirement. Kenya has one of the highest levels ... -
Foreign Exchange Derivative Pricing with Stochastic Correlation
(Scientific Research Publishing, 2016)Financial markets are known to be far from deterministic but stochastic and hence time dependent correlation tends to suit the markets. We price for European Options by using three dimensional assets under stochastic ... -
A Fumonisins Immunosensor Based on Polyanilino-Carbon Nanotubes Doped with Palladium Telluride Quantum Dots
(2014-12-24)An impedimetric immunosensor for fumonisins was developed based on poly(2,5-dimethoxyaniline)-multi-wall carbon nanotubes doped with palladium telluride quantum dots onto a glassy carbon surface. The composite was assembled ... -
Genetic and morphological analyses indicate high population mixing in the endangered cichlid Alcolapia flock of East Africa
(2013)Alcolapia is a minor genus of small-bodied, polymorphic cichlids inhabiting the lagoons and hot springs surrounding the soda lakes Natron (largely in Tanzania) and Magadi (Kenya). Three Alcolapia species are present at ... -
Glossina pallidipes and host interactions: implications of host preference on transmission risk of Rhodesian sleeping sickness in Kenya
(2007)Host preference by tsetse flies, tsetse-host interaction and host diversity and abundance were evaluated in relation to transmission risk of rhodesian sleeping sickness in two tsetse subpopulations in Kenya. Bovidae provided ... -
“God Didn’t Make a Mistake in Creating Me”: Intrapersonal Resilience Processes among Gay and Bisexual Male Youth in Kenya
(MDPI, 2021)Gay and bisexual male youth in Kenya experience human rights violations, including pervasive stigma and discrimination, and these oppressive forces are associated with elevated rates of mental health concerns. Despite ... -
