Flight Loads Analysis with Inertially Coupled Equations of Motion

open access: yes, 2005
In this work an approach for simulation of a large passenger aircraft with high precision equations of motion and a new method of dynamic loads calculation is presented, which can be used for maneuver and gust loads analysis in the time domain. Equations

Arclength parametrized Hamilton's equations for the calculation of instantons

open access: yes, 2014
A method is presented to compute minimizers (instantons) of action functionals using arclength parametrization of Hamilton's equations. This method can be interpreted as a local variant of the geometric minimum action method introduced to compute ...

Vibration Suppression Control of a Flexible Gantry Crane System with Varying Rope Length

open access: yesJournal of Control Science and Engineering, 2019
The paper presents a control approach to a flexible gantry crane system. From Hamilton’s extended principle the equations of motion that characterized coupled transverse-transverse motions with varying rope length of the gantry is obtained. The equations

Quantum Hamilton-Jacobi Equation [PDF]

open access: yesPhysical Review Letters, 1998
The nontrivial transformation of the phase space path integral measure under certain discretized analogues of canonical transformations is computed. This Jacobian is used to derive a quantum analogue of the Hamilton-Jacobi equation for the generating function of a canonical transformation that maps any quantum system to a system with a vanishing ...

Higher-order Euler-Poincar\'e field equations [PDF]

open access: yes, 2023
We develop a reduction theory for $G$-invariant Lagrangian field theories defined on the higher-order jet bundle of a principal $G$-bundle, thus obtaining the higher-order Euler-Poincar\'e field equations.

Invariante adiabático gerado por lenta variação de coordenada generalizada

open access: yesRevista Brasileira de Ensino de Física
Apresentamos estudo de sistema mecânico em que uma coordenada generalizada está sujeita a lenta variação, realizado através de tratamento hamiltoniano no qual se permite a ação de força generalizada ao longo daquela coordenada, gerando o invariante ...
