Numerical Simulations for Fuel Aircraft Management System [PDF]
INCAS Bulletin, 2019 The Fuel Management Systems for civil aircrafts have a direct impact on the airlines profitability, competitiveness and sustainability, because the fuel represents the highest cost for airlines, on average 32% of overall operating costs; extra costs can ...

Numerical simulations of ICME–ICME interactions
Journal of Space Weather and Space Climate, 2019 We present hydrodynamical simulations of the interaction of Coronal Mass Ejections (CME) in the Interplanetary Medium (IPM). In these events, two consecutive CMEs are launched from the Sun in similar directions within an interval of time of a few hours ...

Rethinking materials simulations: Blending direct numerical simulations with neural operators
npj Computational MaterialsMaterials simulations based on direct numerical solvers are accurate but computationally expensive for predicting materials evolution across length- and time-scales, due to the complexity of the underlying evolution equations, the nature of multiscale ...

Conserving Local Magnetic Helicity in Numerical Simulations
The Astrophysical Journal, 2023 Magnetic helicity is robustly conserved in systems with very large magnetic Reynolds numbers, including most systems of astrophysical interest, and unlike kinetic and magnetic energy, it is not dissipated at small scales.

Searching for Critical Conditions During Lifeboat Launching – Simulations
Polish Maritime Research, 2017 The article describes numerical simulations of the process of lifeboat launching at the ship’s side. The research aimed at finding the values of ship motion parameters which appear to be most dangerous for people in the lowered lifeboat due to the ...

Global dynamical properties of two discrete-time exponential systems
Journal of Taibah University for Science, 2019 We explore the global dynamics of following three directional discrete-time exponential systems of difference equations: \[{x_{n + 1}} = \frac{{{\alpha _{19}} + {\beta _{19 }}{e^{ - {y_n}}}}}{{{\gamma _{19}} + {z_{n - 1}}}},\,\quad {y_{n + 1}} = \frac{{{\
