In this paper, we have introduced some concepts about topological dynamical systems and proved some new corollary and theorems of transitivity of a theta irresolute function defined on topological space.

Ridge Regression is an important statistical method in modeling vehicle crash frequency when crash data contains collinear predictors. The term multicollinearity refers to the condition in which two or more predictors are highly correlated with one another. This would make the explanatory variables become very sensitive to small changes in the model. Multicollinearity reduces the precision of the estimated coefficients, which weakens the statistical power of the regression model. Common methods ...

The enactment of Ghana’s high school mathematics enjoins mathematics teachers to provide wellsuited classroom instruction that engages students physically and cognitively. Since learners’ context factors can compromise the instructional efforts of mathematics teachers in delivering the curriculum, this study sought to explore the associations between the levels of students’ mathematics learning and mathematics anxiety with their gender, school type and learning styles. A descriptive survey invo...

A simple subset of an epidemic population model for HIVAIDS can be split into the following: Susceptible, HIVInfected, AIDSinfected, and Removed subsets (SHAR). We consider that the rate at which susceptible people become infected is proportional to the number of encounters between susceptible and infected individuals, which is proportional to the product of the two populations. A nonlinear model is developed and its solution is produced with an Excel numerical approach using difference equa...

Statistical techniques are important tools in modeling research work. However, there could be misleading outcomes if sufficient care is undermined in choosing the right approach. Employing the correct analysis in any research work needs deep knowledge on the differences between these tools. Incorrect selection of the modeling technique would create serious problems during the interpretation of the findings and could affect the conclusion of the study. Each technique has its own assumptions and p...

Surface integrals of vector fields play an important role in the solutions of natural science and physical science. The Gauss theorem reduces the difficulty of directly computing surface integrals of vector fields. This paper introduces an approach for the computation of integral surfaces in vector fields and obtains a generalized mathematical expression based on Gauss theorem. Moreover, the computation time is investigated by two classical examples.

In this paper, we provide a rigorous derivation of asymptotic formula for the largest eigenvalues using the convergence estimation of the eigenvalues of a sequence of selfadjoint compact operators based on the polarisation tensors of perturbations resulting from the presence of small inhomogeneities reported with numerical tests for the Laplace operator.

A recent publication finds strong evidence for a violation of the Cosmological principle of isotropy across the CMB sky. This analysis revealed three distinct patches in the maps with circularlyaveraged sizes between 40 to 70 degrees in radius. These three areas distinguish largescale deviations from the allsky mean value of several distinguished cosmological parameters measured separately. In this article, we analyze these results with a previous solution proposed to explained dark energy co...

The emergence of novel coronavirus (Covid19) in 2019 sprung a sudden outbreak across the globe, presenting clinical and public health management challenges which led to global cancellation of conferences, travel restrictions, social distancing and closure of institutions. Thus, in considering the grave implications of the continuous spread of coronavirus disease, a SEIHRD epidemic model was formulated to gain insight into disease transmission dynamics with impacts of proposing control measures....

In this paper, we establish some midpoint type and trapezoid type inequalities via a new class of fractional integral operators which is introduced by Ahmad et al. We derive a new fractionaltype integral identity to obtain DragomirAgarwal inequality for mconvex mappings. Moreover, some inequalities of HermiteHadamard type for mconvex mappings are given related to fractional integrals with exponential kernels. The results presented provide extensions of those given in earlier works.
