Binomial Mixtures Based on Beta Prior Distributions and their Generalizations
(JOOUST, 2018)A mixed distribution can be obtained when two or more distributions are combined. The integral of the product of the mixture is determined for continuous case and for the discrete the sum of the product ... 
Characterization of Continuity and Convergence of Fredholm Operators Perturbed by Orthogonal Idempotents in Banach Spaces
(JOOUST, 2021)Fredholm operators have been studied by several researchers for decades whereby they developed a comprehensive theory for integral equations and integral operators. A lot of properties of Fredholm operators have been given ... 
Characterization of Essential Numerical Rangers and DavisWielandt Shells of Hilbert Space Operators.
(JOOUST, 2019)The study of the Davis Wielandt shell forms a very important generaralization of the numerical range in functional analysis. Hiroshi Nakazito and MaoTing Chien studied the connections between the qnumericol ... 
Characterization of Similarity Orbits of Invariant Subspaces of NormAttainable Operators.
(Jooust, 2019)Abstract The notion of similarity orbits(S(T)) of Hilbert space operators have been extensively investigated by many researchers such as Herrero, Fialkow and Had• win among others. Various ...

(JOOUST, 2020)corporate governance remains a key area of strategic management and continues to attract tremendous attention from the academia and practitioners. A plethora of studies have exam med the relationship between ... 
Correlation Between the Degree of Alignment and OptoPiezoelectric Properties of Cellulose Nanocrystals Fabricated From Water Hyacynth
(2023)Cellulose nanomaterials have recently continued to attract higher attention in the current research output, due to their extremely excellent mechanical, optical as well as electrical properties. Their sustainability coupled ... 
Effect of Pollution Gradient on Sediment Bacterial Composition and Potential Pathogens in UrbanizationImpacted Streams Draining into Lake Victoria
(Jooust., 2022)Despite urban rivers/streams draining into Lake Victoria suffering from urbanization linked anthropogenic pollution, little is known about their microbiome diversity and structure, or how they respond to intensive ... 
Estimation of Finite Population Mean in the Presence of NonResponse and Measurement Errors in Stratified Two Phase Sampling
(JOOUST, 2021)The problem of estimation of the population mean in the presence of response bias and social desirability bias is common in surveys. Researchers have proposed estimators of the population mean using auxiliary variables in ... 
Estimation of volatility using mean reverting Europeanlogistic type option pricing model.
(JOOUST, 2016)Mean reversion is a mathematical concept that is frequently and widely used in stock investing, modeling interest rates and modeling commodities. In particular there is consensus that a commodity ... 
The Exponentially Modified Gaussian Function as a Tool for Deconvolution of Astroparticle Physics data.
(University of Siegen, 201603)An analysis of the mass composition of UHECRs based on the Xmax elongation rate (ER) within the energy range 1017.8−1020.0eV is performed, using Xmax data collected by the Pierre Auger Observatory from December 2004 to ... 
Extension of Stage Based Projection Matrices in Population Modeling of Invasive Tree Species
(JOOUST, 2021)Matrix models can be used to predict population dynamics and assess management options. Invasive trees proliferation within forest ecosystems have not been characterized, hence the need of population dynamics description ...
