On Centre Properties of Irreducible Subalgebras of Compact Elementary Operators
(doi:10.30538/psrp-oma2020.0065, 2020)
In this paper, we characterize the centre of dense irreducible subalgebras of compact elementary operators that are spectrally bounded. We show that the centre is a unital, irreducible and commutative C∗ -subalgebra. ...
Sensitivity Analyses of Population Projection Matrix of Cestrum Aurantiacum
(Kenya Forestry Research Institute/Jaramogi Oginga Odinga University of science and Technology., 2020)
The Lefkovitch stage specific matrix population models are divided into discrete stage classes defined by a growth variable such as size, height and diameter at breast height for trees. In matrix model, the deterministic ...
Extensions of Lefkovitch Matrix for Modeling Invasive Cestrum Aurantiacum Population Dynamics
(KEFRI/, Jaramogi Oginga Odinga University of science and Technology., 2020)
Modeling of invasive species using stage based matrix methods can be exploited to understand population dynamics of plants using stage based Leftkovitch matrix models. This study reviewed and extended the stage based matrix ...
Use of Semiochemicals for Surveillance and Control of Hematophagous Insects
(Chemoecology, 2020-06-23)
Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, ...

(International Journal of Scientific and Research Publications, 2020-02)
The study was conducted in Eastern Mau is one of the East Mau forest is an important watershed within the Mau Forest Complex, feeding major rivers and streams that make up the hydrological systems of Lake Victoria and ...
Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal of Multidisciplinary Sciences and Engineering, 2020)
In this paper, a nonlinear fourth order evolution equation is investigated by the Lie symmetry analysis approach. All the geometric vector fields and the Lie groups of the evolution equation are obtained. Finally, the ...
Volatility Estimation Using European-Logistic Brownian Motion with Jump Diffusion Process
(International Journal of Mathematics And its Applications, 2020)
Volatility is the measure of how we are uncertain about the future of stock or asset prices. Black-Scholes model formed the foundation of stock or asset pricing. However, some of its assumptions like constant volatility ...
Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal Of Multidisciplinary Sciences And Engineering, 2020-03)
The predator-prey equations were developed and used by Lotka and Volterra to analyze the dynamics of biological systems in which two species interact, one as a predator and the other as prey [3]. Several attempts have been ...
Relative Efficiency of Sum Constructed Automorphic Symmetric Balanced Incomplete Block Designs
(ResearchGate, 2020)
Several construction methods have been introduced to build the elements of BIBDs’ for specific parameters, with different techniques suggested for testing their existence, still no general technique to determine the ...
