An Assessment of Suitable and Affordable Smart armband for preeclampsia Management in Antenatal Care
(2019-06)Blood pressure is one of the measurements that is taken during antenatal care visits. Though motherhood is a fulfilling experience in the society, it is connected to ill-health and even death in some women leading to ... -
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 ... -
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 ... -
A uniform circular array of isotropic sensors that stochastically dislocate in three dimensions—The hybrid Cramér-Rao bound of direction-of-arrival estimation
(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 ... -
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. ... -
Crame´R-Rao Bound of Direction Finding using Uniform Circular Array And 2-Circle Concentric Uniform Array
(2019-09)Source direction-of-arrival estimation problem has received much attention in recent years following its significant role in array-signal processing and wide range of applications such as radar, wireless communication, ... -
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 ... -
Ranks, Subdegrees and Suborbital graphs of the product action of Affine Groups
(UoEm, 2020)The action of affine groups on Galois field has been studied. For instance, [3] studied the action of 𝐴𝑓𝑓 (𝑞 ) on Galois field 𝐺𝐹 (𝑞) for 𝑞 a power of prime 𝑝. In this paper, the rank and subdegree of the direct ... -
Ranks and Subdegrees of External Direct Product of Cn Dr Acting on X Y
(UoEm, 2020)In this paper, transitivity, ranks and subdegrees of the action of ex- ternal direct product of Cyclic and Dihedral group on Cartesian Product of two sets are determined. The action is proved to be transitive. Also, it's ... -
MODELING DISPROPORTIONAL EFFECTS OF EDUCATING INFECTED KENYAN YOUTH ON HIV/AIDS
(journal of biological systems, 2020)We formulate an age and sex-structured deterministic model to assess the effect of increasing comprehensive knowledge of HIV/AIDS disease in the infected Adolescent Girls and Young Women (AGYW) and, Adolescent Boys and ... -
Socio-Demographic Factors And Knowledge Influencing Associated With ORS Use For Diarrhoea In Children At Miathene Sublocation, Meru County, Kenya
(2020-05)Oral rehydration solution is the gold standard treatment option in childhood diarrhoea though there are other practices like use of rice water, water sugar mixtures, continuous breast feeding for under six months ... -
Medical Device Integration with Electronic Health Records: A Case Study of University of Nairobi Health Services, Kenya
(2020-06)In this study, we describe a demonstration in which available electronic medical records system (EMR) was successfully integrated with a wireless blood pressure monitor (BPM). This was implemented by adopting the use of ... -
Universal Health Coverage
(2020-09)Universal Health Coverage has attracted global attention as an ideal vehicle that will drive health care services to the individuals, families, and communities globally. Good health systems are capable of serving 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 ... -
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 ... -
