Multivariate descriptive measures for location and scatter are the foundation of multivariate statistics and underpin many methods in the field. In this paper, we propose and study some new general depth-based trimmed means and trimmed scatter matrices. In ad…

This study applies the variance-covariance technique to estimate the Value at Risk (VaR) of OPEC crude oil prices. To capture the variability, heavy tails, and uncertainty in the dataset, three distributions were utilized within an ARIMA-GARCH framework: Norm…

The dissipative term in the Rayleigh oscillator contains a nonlinear (cubic) contribution. Usually, the coefficient, ε , of the dissipative term is assigned a small value. The solution evolves into a limit cycle with O (1) maximal amplitude, maximal velocity…

Reproducing kernel Hilbert space method is utilized in this paper as an efficient approach to solve singular fourth order boundary value problems of mixed form Fredholm-Volterra integro-differential equations. In order to obtain the required nodal values, the…

In this article, we use quaternions together with Kustaanheimo-Stiefel transformation to solve the Kepler problem, first its unperturbed version and then when adding a small perturbing force. We assume that the perturbing force is autonomous, which enables us…

The current paper numerically tackles the class of fractional ordinary boundary value problems using the modification method of the classical Adomian decomposition method and through a fractional inverse operator. Among the advantages of the adopted fractiona…

As a key medium for transferring knowledge across disciplines, mathematical symbols do not undergo a direct formal transfer when applied in computer science and physics. Rather than simple reuse, this process involves a structured transformation that includes…
