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 ... -
Rank and Subdegrees of PGL(2; q) Acting Cosets of PGL(2; e) for q an Even Power of e
(UoEm, 2019)The action of projective general group on the cosets of its maximal subgroups has been studied. For instance, [9] studied the action of G on the cosets of PGL(2; e) when q is an odd prime power of e. In this paper, we ... -
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 ... -
Application of Marks to Computation of Ranks and Subdegrees of the Symmetric Group Acting on Ordered 4-Element and 5- Element Subsets
(UoEm, 2015)Ranks and subdegrees can be computed using combinatorial arguments, the Cauchy-Frobenius lemma and use of the concept of marks. However the concept of Marks has been given very little attention. In this paper we will apply ... -
Cycle Index Formulas for D n Acting on Unordered Pairs
(Uoem, 2015)The cycle index of dihedral group D n acting on the set of X the vertices of a regular n- gon was studied (See [1]). In this paper we study the cycle index formulas of D n acting on unordered pairs from the set . In each ... -
Application of Marks to Computation of Ranks and Subdegrees of the Symmetric Group Acting on Ordered Pairs and on Ordered Triples
(Uoem, 2014)Ranks and subdegrees can be computed using combinatorial arguments, the Cauchy-Frobenius lemma and use of the concept of marks. However the concept of Marks has been given very little attention. In this paper we will apply ... -
Action of PGL(2,q) on the Cosets of the Centralizer of an Eliptic Element
(Uoem, 2021-08-19)Most researchers consider the action of projective general group on the cosets of its maximal subgroups leaving out non-maximal subgroups. In this paper, we consider the action of PGL(2,q) centralizer of an elliptic ... -
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 ... -
Modeling the effects of insecticides resistance on malaria vector control in endemic regions of Kenya
(Elsevier Ltd., 2018-12)We present a model to investigate the effects of vector resistance to control strategies. The model captures the development of resistance as well as loss of resistance in mosquitoes and how these affect the progress in ... -
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 ... -
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 ... -
Modeling the Effect of HIV/AIDS Stigma on HIV Infection Dynamics in Kenya
(springer, 2021-03-15)Stigma toward people living with HIV/AIDS (PLWHA) has impeded the response to the disease across the world. Widespread stigma leads to poor adherence of preventative measures while also causing PLWHA to avoid testing and ... -
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 ... -
Aperture Maximization with Half-Wavelength Spacing, via a 2-Circle Concentric Array Geometry that is Uniform but Sparse
(Journal of Advances in Mathematics and Computer Science, 2019-05-25)This paper proposes a new sensor-array geometry (the 2-circle concentric array geometry), that maximizes the array’s spatial aperture mainly for bivariate azimuth-polar resolution of direction-of-arrival estimation ... -
