The Frimmer-Novotny model to simulate two-level systems by coupled oscillators is extended by incorporating a constant time delay in the coupling. The effects of the introduced delay on system dynamics and two-level modeling are then investigated and found substantial. Mathematically, introducing a delay converts the dynamical system from a finite...

We address the portfolio optimization problem using the global minimum variance portfolio (GMVP). The GMVP gives the weights as a function of the inverse of the covariance matrix (CM) of the stock net returns in a closed-form. The matrix inversion operation usually intensifies the impact of noise when the matrix is ill-conditioned, which often happ...
In this work, we conduct a comparison for various delay differential equations’ solvers to determine the strength and weakness points of each one. The comparison is clarified through a numerical example in which we consider the coupled harmonic oscillators. We obtain the eigenvalues of the delayed coupled harmonic oscillators system by solving the...
