OPTICAL SIGNAL TRANSMISSION IN NEW GENERATION FIBRES USING ADVANCED MODULATION FORMATS AND VCSEL TRANSMITER
(University of Eldoret, 2021)In the current society, the data transmitted using the internet is tremendous and has been occasioned by the rapid broadening of communication infrastructure. The use of traditional NRZ format is becoming less applicable ... -
OPTIMAL DESIGN FOR SECOND-DEGREE KRONECKER MODEL MIXTURE EXPERIMENTS FOR MAXIMAL PARAMETER SUBSYSTEM
(University of Eldoret, 2014)Products in many disciplines frequently involve blending two or more ingredients together. The design factors in a mixture experiment are the proportions of the components of a blend, and the response variables vary ... -
Optimal Kiefer Ordering of Simplex Designs for Third-Degree Mixture Kronecker-Models with three ingredients.
(Mathematical Theory and Modeling, 2019)This paper investigates the Kiefer optimality in the third-degree Kronecker model for mixture experiments. For mixture models on the simplex, a better design is obtained, by matrix majorization that yields a larger ... -
Optimisation of plutonium separations using TEVA cartridges and ICP-MS/MS analysis for applicability to large-scale studies in tropical soils
(The Royal Society of Chemistry, 2023-08)The analysis of plutonium (Pu) in soil samples can inform the understanding of soil erosion processes globally. However, there are specific challenges associated for analysis in tropical soils and so an optimal analytical ... -
OPTIMISING A RESTING BOX TO ENHANCE ADULT GRAVID FEMALE MOSQUITOE AUTO-DISSEMINATE LARVICIDE IN A SEMI FIELD
(2018)Malaria control strategies that target adult mosquitoes are challenged by the emergence of insecticide resistance and behavioral changes of vectors. The conventional approach of applying larvicides is limited by high ... -

Optimization of Split-Plot Design in the Context of Mixture Process Variable Settings
(Asian Journal of Probability and Statistics, 2021-04)In the presence of process variables, a mixture design has become well-known in statistical modeling due to its utility in modeling the blending surface, which empirically predicts any mixture's response and serves as the ... -
Optimizing a Gravid Mosquito Resting Box to Enhance Auto-dissemination of Larvicides under Semi-Field Conditions in Western Kenya
(Journal of Mosquito Research, 2019)Malaria control strategies are challenged by emergence of insecticide resistance and behavioral changes of the vector. New vector management tools are required to avert control failure. The aim of this study was to ... -
OVERALL CENTRAL MOMENTS OF TRAFFIC DELAY AT A SIGNALIZED INTERSECTION
(University of Eldoret, 2013)Overall traffic delay model for estimating the mean and variance at a signalized intersection is discussed. The model was developed under basis of two delay components, namely deterministic and stochastic components. The ... -
Parametric Interval Estimation of the Geeta Distribution
(International Journal of Statistics and Probability, 2018)t is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained ... -
Parametric Point Estimation of the Geeta Distribution
(International Journal of Statistical Distributions and Applications, 2018)Geeta distribution is a new discrete random variable distribution defined over all the positive integers with two parameters. This distribution belongs to the family of Location-parameter (LDPD) system and is of the form ... -
PARASITOLOGICAL AND ECOLOGICAL ASSESSMENT OF SMALL WATER BODIES (SWBs) FOR PRODUCTION OF TILAPIA (Oreochromis niloticus L.) IN UASIN GISHU AND SIAYA COUNTIES, KENYA
(University of Eldoret, 2015)Sustainability of culture-based fisheries (CBF) development in small water bodies (SWBs) largely depends on their ecological conditions and productivity. Studies were conducted from November 2010 to July 2012 in Kesses and ... -
