    Abstract: The design and development of optical systems relies on a thorough theoretical understanding of optical aberrations. However, determining the values of the various-order wavefront aberrations in an optical system is extremely challenging. Accordingly, the present study proposes a methodology for determining the numerical values of the secondary wav... Show More

    Abstract: Mathematics is a subject that is widely applied in solving science problems. There has been an argument that to perform well in sciences, one must also perform well in mathematics. In the light of this assertion, this paper studied the correlation between mathematics and science subjects’ achievements in secondary schools. Two science subjects, phy... Show More
  • Analytical and Numerical Solutions for the (3+1)-dimensional Extended Quantum Zakharov-Kuznetsov Equation

    Abstract: The Zakharov-Kuznetsov equation is an important model to describes the nonlinear pulse propagation in plasma physics, which guides the characteristic of weakly nonlinear ion-acoustic waves in plasma composed of cold ions and hot isothermal electrons in a uniform magnetic field. In the current study, we investigate the generalized trigonometric solu... Show More

    Abstract: Let A(G) be the adjacency matrix of graph G. Suppose λn ≤ λn-1 ≤ ··· ≤λ1 are the eigenvalues of A(G). The energy of a graph G is denoted by ε(G), which is defined as the sum of absolute values of its eigenvalues. It is well known that graph energy is found that there are many applications in chemistry. Nikiforov showed that almost all graphs have a... Show More
