A Theoretical Model of Corruption Using Modified Lotka Volterra Model A Perspective of Interactions between Staff and Students
(2020-09)Corruption is the misuse of power or resources for private gain. This undermines economic development, political stability, and government legitimacy, the society fabric, allocation of resources to sectors crucial for ... -
Simulation of a Deterministic Model of HIV Transmission between Two Closed Patches
(2020-09)Numerical simulation of a deterministic model of HIV transmission between major cities in Kenya is carried out. The model considered two closed patches connected by the commuter movements of truck drivers being the ... -
Parameterization and Forecasting of Childhood Pneumonia Model Using Least Square Approximation, Lagrange Polynomial and Monte Carlo Simulation
(2020-09)espite a study by [1] proposing a simple model of under five years pneumonia, doubt lingers regarding its reliability, sufficiency and validity. The research question is whether the model is valid for use or not? The ... -
Hybrid Cram er-Rao bound of direction finding, using a triad of cardioid sensors that are perpendicularly oriented and spatially collocated
(Acoustical Society of America, 2019-07)Cardioid microphones/hydrophones are highly directional acoustical sensors, which enjoy easy availability via numerous commercial vendors for professional use. Collocating three such cardioids in orthogonal orientation ... -
Socio-Demographic Factors And Knowledge Influencing Associated With ORS Use For Diarrhoea In Children At Miathene Sublocation, Meru County, Kenya

A uniform circular array of isotropic sensors that stochastically dislocate in three dimensions—The hybrid Cramer-Rao bound of direction-of-arrival estimation
(Acoustical Society of America, 2019-07)An array’s constituent sensors could be spatially dislocated from their nominal positions. This paper investigates how such sensor dislocation would degrade a uniform circular array (UCA) of isotropic sensors (like ... -
Cramer-Rao Bound of Direction Finding Using Uniform Arc Arrays
(2019)Direction-of-Arrival estimation accuracy using arc array geometry is considered in this paper. There is a scanty use of Uniform Arc Array (UAA) in conjunction with Cram er-Rao bound (CRB) for Direction-of-Arrival estimation. ... -
Medical Device Integration with Electronic Health Records: A Case Study of University of Nairobi Health Services, Kenya
