(Journal of Agricultural Extension, 2021-10)The study investigated the socioeconomic and institutional factors influencing uptake of multiple climate change adaptation practices among smallholder farmers in lower Eastern Kenya. Multistage sampling procedure was used ...
-
(Journal of Agricultural Extension, 2021-10)This study ascertained the socioeconomic determinants of farmers’ knowledge on soil and water conservation technologies in Dry zones of Central Highlands of Kenya involving 400 farming households. Results showed that the ...
-
(Acoustical Society of America, 2017-11-15)Consider azimuth-elevation direction finding by a uniform circular array of isotropic sensors. In the real world, the sensors may dislocate from their nominal positions. These dislocations could be modeled as random variables ...
-
(Acoustical Society of America, 2019-03)This presentation characterizes the source-localization precision obtainable via "received signal strength indication" (RSSI) based on data from a tri-axial velocity sensor and a spatially separated pressure sensor. That ...
-
(IEEE, 2021-06)Azimuthal centrosymmetry in an array grid is typically associated with arrays that are circular, concentric, cylindrical, spherical, or hemispherical. However, a recently proposed alternative combines an azimuthal circular ...
-
(IEEE, 2021-01-15)The L-shaped and V-shaped arrays of first-order cardioid microphones for direction finding are presented in this paper. A comparative study of the direction of arrival estimation performance of the arrays was carried out ...
-
(Acoustical Society of America, 2020-05)The linear array’sone-dimensional spatial geometry is simple but suffices forunivariate direction finding, i.e., isadequate for the estimation of an incident source’s direction-of-arrival relative to the linear ...
-
(European Scientific Journal, 2019-07)Public Private Partnership (PPP) is a long term agreement between the public and private sector where risks and rewards are shared in developing a public facility. Private sector play a monumental role in bridging ...
-
(IEEE, 2018)A rectangular array of sensors is often used in direction finding, due to the geometric regularity in its spatial rectangular grid. The sensor positions may be confined to the rectangle's perimeter (as in a “rim” array), ...
-
(IJMEC, 2020-01)A two-dimensional direction-of-arrival estimation scheme based on Bayesian-regularized (BR) Multilayer Perceptron (MLP) artificial neural network (ANN) is developed around a unit acoustic vector sensor (AVS). The AVS ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(Science Domain, 2018-11-22)Decomposition of recurrent curvature tensor fields of R-th order in Finsler manifolds has been studied by B. B. Sinha and G. Singh [1] in the publications del’ institute mathematique, nouvelleserie, tome 33 (47), 1983 pg ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
