Journal of Computational Methods In Engineering, Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy.
It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. On the other hand, the symplectic integrators due to their structure can cope with this problem and act more accurately in comparison to the finite difference method.
They reduce the computation cost and do not face numerical dispersion when time interval is increased. Therefore, the aim of the current paper is to present a symplectic integrator for wave-field extrapolation using the Euler method. Then, the extrapolation is implemented for rather large time intervals using a simple geological model. The extrapolation employed for both symplectic Euler and finite difference. The paper examines the first phase of the formation and elaboration of the language of Greek philosophy, showing that it is largely based on a resemantization of everyday language.
Furthermore, I focus on the sort of philosophical dictionary that is book 5 of Aristotle's Metaphysics. Aristotle's analyses denote the philosopher's significant awareness of a linguistic process that took place historically. Color images from online version have been added to black and white scan.
