Normal form stability estimates are a basic tool of Celestial Mechanics for characterizing the long-term orbits natural and artificial bodies. Using high-order normal constructions, we provide three different orbital point-mass satellites orbiting around Earth. i) We demonstrate long term semimajor axis within framework $J_2$ problem, by construction eliminating fast angle in corresponding Hami...

History matching is used to constrain flow simulations and reduce uncertainty in forecasts. In this work, we revisited some fundamental engineering tools for predicting waterflooding behavior to better understand the flaws in our simulation and thus find some models which are more accurate with better matching. The Craig-Geffen-Morse (CGM) analytical method was used to predict recovery performa...
