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 ... -
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 ... -
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 ... -
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 ... -
Socioeconomic Impact of Establishment of University of Embu on Small Scale Farmers in Nthambo Sub-Location, Kenya
(Asian Journal of Probability and Statistics, 2018-11)The University of Embu is one of the fast developing and recently chartered University in Kenya. It is located in Nthambo sub-location, which is an agricultural potential area. Universities establishment have considerable ... -
A Theoretical Model of Corruption Using Modified Lotka Volterra Model: A Perspective of Interactions between Staff and Students
(Journal of Advances in Mathematics and Computer Science, 2020-08)Corruption is the misuse of power or resources for private gain. This undermines economic development, political stability, and government legitimacy, the society fabric, allocation of resources to sectors crucial for ... -
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 ...
