Determinants of Electronic Health in Developing Countries
(2014-04)Limitations of paper-based records are influencing a transition across the globe towards Electronic Health Records (EHRs) and in general electronic health (eHealth). However, despite the well documented benefits of eHealth, ... -
Determinants of Mobile Apps in C++ Programming Course: A reviewed Literature
(2017-10)In recent times, the use of mobile applications (mobile apps) has become undeniable where it permits people perform thousands of tasks through the use of smartphones, tablets or other related devices. The purpose of the ... -
A Deterministic Model Of HIV Transmission Between Two Closed Patches Incorporating The Monod Equation
(IISTE, 2019-11-06)Among other factors, migration has significantly contributed to the spread of HIV. Recent studies have revealed that new infections occur along major transport corridors and truck-drivers have overall higher prevalence ... -
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 ... -
Effect of Mobile Communication Services on Performance of Saccos in Kenya
(2018-10)The ubiquitous nature of mobile technologies and devices, present new challenges and opportunities for Deposit-Taking Savings and Credit Cooperative Societies (SACCOs) as they integrate them into their processes with ... -
Effects of Culture Conditions on Growth of Kefir Grains using Milk for Nutrition and Health: An Application of Response Surface Methodoly with Box-behnken Design
(IISTE, 2018)This combined process was successfully modeled by response surface methodology method with a Box– Behnken design. In this work, Box-Behnken Design of response surface methodology was used to investigate the effects of ... -
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 ... -
Evidence-based modeling of combination control on Kenyan youth HIV/AIDS dynamics
(plos one, 2020-11-17)We formulate a sex-structured deterministic model to study the effects of varying HIV testing rates, condom use rates and ART adherence rates among Adolescent Girls and Young Women (AGYW) and, Adolescent Boys and Young ... -
Extraction of Scene Text Information from Video
(Modern Education and Computer Science, 2016)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 ... -

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 ... -
ICT Devices: Vital Tools for Enhancing Road Traffic Monitoring
(Communications and ,Network, 2018-07-10)Road Traffic monitoring involves the collection of data describing the charac- teristic of vehicles and their movement through road networks. Such data may be used for one of these purposes such as law enforcement, ... -
The Impact of Labor Contract and Labor Union on Social Security Right
(Scientific Research Publishing Inc., 2018-04-23)Based on ten cities’ workers data about the employment situation of the worker in 2010, the paper analyzes the influence of labor contract and labor union on social security rights by using binary logistic regression ... -
Implementation of Blockchain Technology in Africa
(European Centre for Research Training and Development UK, 2019-08)Africa is currently tackling challenges to technologies and innovation in its suitable development agenda.in the journey to embracing the blockchain technology, ICT plays a very vital role in addressing the challenges. ... -
Information Technology In Government Services Delivery: A Case Study Of Huduma Center Kenya
(2018-12)The Huduma Kenya program was developed by the Kenyan government with an aim of using technology to improve the service delivery to the citizens. The Program uses many channels to meet different and varied needs of the ... -
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 ... -
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 ... -

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 ... -
A Mathematical Model of Contact Tracing during the 2014–2016 West African Ebola Outbreak
(MDPI, 2021-03-12)The 2014–2016 West African outbreak of Ebola Virus Disease (EVD) was the largest and most deadly to date. Contact tracing, following up those who may have been infected through contact with an infected individual to ...
