This study focused on linear convection-diffusion problems with constant coefficients with a view of providing the solution with the help of Mahgoub Transform. Convection-diffusion problems can be used to model the behavior of flow phenomena such as momentum and heat, and as well describe the diffusion process in environmental science, such as poll...

This article aims at depicting the genuity and usefulness of the amalgamated technique known as Homotopy perturbation with Mahgoub Transformation in unveiling the particular and coarse-grained solutions of the equation of Korteweg-de Vries of third order and nonlinear. Considered for illustrations were three cases with the proposed mechanism engage...

There had been an urgent call for the collection of standardized data describing clinical presentations, severity, outcomes, and epidemiology of COVID-19 by the World Health Organization (WHO). These data were expected to compliment the national pandemic data collated from countries by the World Health Organization (WHO). Nigeria, among other count...

Phishing is an internet crime achieved by imitating a legitimate website of a host in order to steal confidential information. Many researchers have developed phishing classification models that are limited in real-time and computational efficiency. This paper presents an ensemble learning model composed of DTree and NBayes, by STACKING method, wit...

Referral techniques are normally employed in internet business applications. Existing frameworks prescribe things to a particular client according to client inclinations and former high evaluations. Quite a number of methods, such as cooperative filtering and content-based methodologies, dominate the architectural design of referral frameworks. Man...

This study aims to screen bacterial isolates from Olabisi Onabanjo University Farmland for antibacterial activity against pathogenic microorganisms. Agar well diffusion method was used. Isolates were identified molecularly. Chi-square test revealed significant association between isolates, antibacterial activity with likelihood p-value = 0.000 and...

Two-phase sampling for regression has proven to be efficient in estimation especially when there is high correlation coefficient between the study and the auxiliary variable(s). However, the presence of extreme value makes the distribution to violate the basic statistical assumptions. Violation of linearity assumption by the concerned distribution,...

In survey sampling, auxiliary variables and attributes have been employed to reduce the Mean Square Error (MSE) of estimators, hence, improving such estimators in Two-Phase sampling. Similarly, the three ways of utilizing auxiliary variables and attributes (full, partial and no information cases) have provided flexibility in its usage. In this arti...

Double Sampling for regression is an advanced sampling and estimation method in Statistics. Sahoo's Chain regression in 1993 was a case study of double sampling for regression where two auxiliary variables (and) are used. Authors have established that ridge regression performs better than Ordinary Least Squares (OLS) estimation in the presence of c...

Funding Nigerian Government owned Institutions has been the responsibility of the Government. Federal Institutions have been enjoying the ease flow of cash from the federal government. However, State-owned Government Institutions like Olabisi Onabanjo University, as revealed in THE NATION Newspaper, has been faced with under-funding from her host G...

Google classifies software raters as software end-users and established that raters' experience is a good criterion for judgement of software quality on online software repositories (OSR). Knowing the number of end-users helps in planning and management of repositories, software development and software usage for countries and OSR managers. Scaffid...

Online Software Repositories (OSR) like sourceforge.net and google code contain a wealth of valuable data about software projects but these data violate the linearity and normal assumptions, hence making the data impossible for use in most statistical data analysis. To prepare these data for statistical data analysis, the data were non-linearly tra...

This research work takes into consideration the Double sampling procedure to determine the efficient estimator among the double sampling for ratio and regression and Simple random sampling without replacement (SRSWOR) type estimators. The empirical comparison of the minimum variances, relative efficiency and the coefficient of variations were used...
