Three-dimensional dislocations in a uniform linear array's isotropic sensors-Direction finding's hybrid Cramér-Rao bound
(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 ...
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 ...
On the Performance of L- and V-Shaped Arrays of Cardioid Microphones for Direction Finding
(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 ...
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 ...
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 ...

(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 ...
Acoustical Direction Finding using a Bayesian Regularized Multilayer Perceptron Artificial Neural Networks on a Tri-Axial Velocity Sensor
(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 ...
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 ...
