Comparing the “Rim” Versus the “Filled” Rectangular Array Grids—Their Direction-Finding Cramér-Rao Bounds
(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), ...
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 ...
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 ...
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 ...
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 ...
Determinants of Participation of Smallholder Farmers in Weather Index Insurance in Embu County, Kenya
(Journal of Agricultural Extension, 2021-07)
The study examined how multiple factors influence participation of farmers in Weather Index Insurance WII in Embu County, Kenya. Data wer e collected from a sample of 401 smallholders following multi stage sampling technique ...
The hybrid Cramer-Rao bound of direction finding by a uniform circular array of isotropic sensors that suffer stochastic dislocations
(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 ...
Amplicon-based assessment of bacterial diversity and community structure in three tropical forest soils in Kenya
(Heliyon, 2022-11)
Forest soils provide a multitude of habitats for diverse communities of bacteria. In this study, we selected three
tropical forests in Kenya to determine the diversity and community structure of soil bacteria inhabiting ...
