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), ...
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 ...
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 ...
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 ...

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 ...
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

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 ...
Farming systems’ typologies analysis to inform agricultural greenhouse gas emissions potential from smallholder rain-fed farms in Kenya
(Elsevier B.V, 2020)
Most sub-Saharan Africa smallholder farming systems are highly heterogeneous. Direct quantification of greenhouse gas emissions from these farming systems is hampered by di- versity at farm-level. Each farm contributes ...
