Nettet9. apr. 2024 · The classical numerical methods for differential equations are a well-studied field. Nevertheless, these numerical methods are limited in their scope to certain classes of equations. Modern machine learning applications, such as equation discovery, may benefit from having the solution to the discovered equations. The solution to an … NettetThese two boundaries exist completely independently of each other. FINALLY, once boundaries have been determined, it’s time to place barricades. To properly barricade, take the greater distance between the arc flash boundary and the limited approach boundary, then set the barricades at or beyond that distance when working energized.
