Rules-of-thumb to design a uniform spherical array for direction finding—Its Cramér– Rao bounds' nonlinear dependence on the number of sensors
(Acoustical Society of America, 2019-02)ABSTRACT This paper discovers rules-of-thumb on how the estimation precision for an incident source's azimuth-polar direction-of-arrival (ϕ,θ) depends on the number (L) of identical isotropic sensors spaced uniformly on ... -
Determinants of smallholders farmers' participation in collective marketing of maize in the central highlands of Kenya
(African Journal of Rural Development, 2019-06-30)Collective marketing has been proposed as a solution to the problem of poor access to markets in developing nations. However, smallholders’ market participation is still limited. This study assessed farmers’ perception ... -
Household socio-economic factors influencing choice of agro-advisory dissemination pathways for climate change in semi-arid areas of Kenya
(Sage publishers, 2021-07-02)Development in Sub-Saharan Africa (SSA) is adversely affected by climate change and variability due to the dependence of its economies and livelihoods primarily on rain-fed agriculture. This creates the need for agro-advisories ... -
Gender-specific determinants of Zai technology use intensity for improved soil water management in the drylands of Upper Eastern Kenya
(Elsevier Ltd., 2021-06-01)Degraded landscapes and soil water stress are long-standing problems to smallholder agriculture in the drylands. Despite the important roles of zai technology in restoring degraded landscapes and improving agricultural ... -
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 ... -

Parameters And State Estimates Of Sex Based Covid-19 Model Using Kenya Data, Nonlinear Least Square And Interpolating Polynomials
(International Journal of Scientific and Research Publications, 2021-05-05)COVID-19 spread in Kenya has been growing at a very high rate in the recent past. According to the Kenya’s ministry of health, the confirmed COVID-19 infections as of 19th July 2020 was 13,353 with recorded 5,122 ... -
Effect of supplemental feeding on habitat and crop selection by wild boar in Sweden
(Taylor & Francis, 2022-01)The wild boar population has increased rapidly during the last 2 decades in Southern and Central Sweden. This rise in population size has caused severe damages to agricultural fields through their foraging behavior. Given ... -
Extension-Market Linkages on Banana Commercialisation Among Smallholder Farmers in Meru Region, Kenya
(2022-01)The study examined the effect of extension-market linkages on banana commercialisation among smallholder farmers in the Meru region, Kenya. The study sampled 400 farmers from a target population of 288,802 from the Meru ... -
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 ... -
Simulation of a Deterministic Model of HIV Transmission between Two Closed Patches
(Journal of Advances in Mathematics and Computer Science, 2020-09-08)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 agents ... -
