Tuberculosis model, a case study of tigania west, Kenya
(2016)Tuberculosis (TB) is a bacterial disease caused by mycobacterium tuberculosis. Many mathematical models for TB have been developed but not specifically for Kenya. This study develops a deterministic model based on ... -
A model for childhood Pneumonia Dynamics
(Asian online journals, 2014)This paper presents a deterministic model for pneumonia transmission and uses the model to assess the potential impact of therapy. The model is based on the Susceptible-Infected-Treatment-Susceptible compartmental structure ... -
Analytical model for childhood pneumonia, a case study of Kenya
(Science Domain International, 2016)Pneumonia is an infection of the lungs that is caused by bacteria, viruses, fungi, or parasites. For a long time to the best of our knowledge there have not been reliable mathematical model for childhood pneumonia in ... -
Estimated numerical results for the deterministic model of the under five years pneumonia in Kenya
(2016)In this paper the numerical results are estimated for childhood pneumonia deterministic model, using Kenyan data. The estimates of data and parameters from Kenya Health information system, ministry of Health of Kenya and ... -
Numerical simulation of the deterministic model of the under-five year’s pneumonia in Kenya
(2016)In this paper the numerical simulation of the childhood pneumonia deterministic model are determined. The estimated parameters and the under-five year’s population data for year 2013 was used to simulate the developed ... -
Modeling Scramble for other tribes votes by the three main tribal voting blocs in Kenya Presidential elections
(2016)A deterministic model was formulated to describe the tribal based voting blocs in Kenya presidential politics using four compartmental classes: Kikuyu (K), Luo (L), AKalenjin (A) and other tribes (T). The first order ... -
A Simple model for the ethnic, sub ethnic, clan and religion based politics in Kenya presidential elections
(2016)A simple deterministic model with Kenya specific attributes was developed to describe the ethnic based voting blocs. Four compartmental classes: Agikuyu (A), Luo (L), Kalenjin (K) and the Rest (R) were formulated, and first ... -
Modeling Influence Tribal Coalitions in Kenya Presidential Politics: A Case Study of Kikuyu-Kalenjin versus Luo-Kamba
(Science Domain International, 2016-04)A deterministic model was developed to describe the two dominant tribal coalition based voting bloc (A and B) and other tribes (C). The first order nonlinear ordinary differential equations were deduced using predator-prey ... -
Modeling Kenya Domestic Radicalization like A Disease Incorporating Rehabilitation Centers
(Academic Research Publishing Group, 2016)The study presents a deterministic model for radicalization process in Kenya and use the model to assess impact of rehabilitation centers to radicalization burden. The possibility of other drivers of radicalization to ... -
An L-shaped Array with Non-Orthogonal Axes – Its Cramer-Rao Bound for Direction Finding
(IEEE, 2017-08)If a nominally L-shaped sensor-array's two legs are not exactly perpendicular, its azimuth-polar direction-of-arrival estimation would be degraded. This paper quantifies this degradation via a deterministic Cramér-Rao ... -
A Lower Bound of Estimation Error of an Emitter's Direction-of-Arrival / Polarization, for a Collocated Triad of Orthogonal Dipoles/Loops That Fail Randomly
(2017-04)For a triad of short dipoles (or of small loops), in perpendicular orientation relative to each other but collocated in space, this study derives a lower bound for their error in direction-of-arrival estimation and ... -
Segmentation and Alignment of Multi-oriented and Curved Text Lines from Document Images
(2015-06)In this paper, we present a novel approach to segment and align multi-oriented and curved text-lines from document images. We assumed that the input document image contains text-lines with arbitrary orientation and ... -
Direction Finding with the Sensors' Gains Suffering Bayesian Uncertainty — Hybrid CRB and MAP Estimation
(IEEE, 2016-08)The paper analyzes how a sensor array's direction-finding accuracy may be degraded by any stochastic uncertainty in the sensors' complex value gains, modeled here as complex value Gaussian random variables. This analysis ... -
Moderating Effect of Government Policies on the Relationship between Mobile Technology Services and Performance of Deposit-Taking Saccos in Kenya.
(2017-02)The study sought to determine the moderating effect of government policies on the relationship between mobile technology services and performance of Deposit-Taking Savings and Credit Cooperative Societies (SACCOs) in ... -
Modelling Vaccination and Treatment of Childhood Pneumonia and Their Implications
(Science Domain International, 2018-07)This paper presents a deterministic model for pneumonia transmission and uses the model to assess the potential impact of the vaccination, treatment and efficacy of vaccination drugs in lowering the public health impact ... -
On Analytical Approach to Semi-Open/Semi-Closed Sets
(2017-03)The concept of open and closed sets has been extensively discussed on both metric and topological spaces. Various properties of these sets have been proved under the underlying spaces. However, scanty literature is available ... -
Extraction of Scene Text Information from Video
(2016-01)In this paper, we present an approach for scene text extraction from natural scene video frames. We assumed that the planar surface contains text information in the natural scene, based on this assumption, we detect planar ... -
Localization of Overlaid Text Based on Noise Inconsistencies
(2015-04)In this paper, we present a novel technique for localization of caption text in video frames based on noise inconsistencies. Text is artificially added to the video after it has been captured and as such does not form part ... -
Application Of Multiple Circular-Linear Regression Models To Animal Movement Data With Covariates
(2016-04)In a many biological and physical sciences studies, a set of techniques have been developed to analyse the relationship between the circular and linear data derived from the geographical positioning system (GPS) telemetry ... -
Spatial Modelling and Mapping of Socio-Demographic Determinants of Infant Mortality in Kenya
(2016-03)This paper addresses the problem of monitoring the infant and child mortality from point referenced data. Indicators of the determinants of child survival based on Mosley and Chen framework are derived and used to model ...
