Port-Hamiltonian Modeling of Systems with Position-Dependent Mass
It is known that straightforward application of the classical Lagrangian and Hamiltonian formalism to systems with mass varying explicitly with position may lead to discrepancies in the formulation of the equations of motion. Systems with mass varying explicitly with position often arise from situations where the partitioning of a closed system of constant mass leads to open subsystems that exc...
متن کاملA model for estimation of stress-dependent deformation modulus of rock mass
Deformation modulus of rock mass has a significant role in the support design of an underground excavation. It is determined by expensive in-situ tests or by empirical models. Existing models for estimation of deformation modulus do not consider its stress dependence. Herein, data from several sources is used to develop a stress- (depth-) dependent relation for estimation of deformation modulus...
متن کاملBRST treatment of the Bohr collective hamiltonian at high spins
The BRST treatment of triaxial systems rotating at high spins is used to solve perturbatively the γ-independent Bohr collective hamiltonian.
متن کاملSolution of the Bohr hamiltonian for soft triaxial nuclei
The Bohr-Mottelson model is solved for a generic soft triaxial nucleus, separating the Bohr hamiltonian exactly and using a number of different model-potentials: a displaced harmonic oscillator in γ, which is solved with an approximated algebraic technique, and Coulomb/Kratzer, harmonic/Davidson and infinite square well potentials in β, which are solved exactly. In each case we derive analytic ...
متن کاملA Hamiltonian System with an Even Term
In this paper we study, using variational methods, a Hamiltonian system of the form −u′′ + u = h(t)V (u), where h and V are differentiable, h is positive, bounded, and bounded away from zero, and V is a “superquadratic” potential. That is, V behaves like q to a power greater than 2, so |V (q)| = o(|q|) for |q| small and V (q) > O(|q|) for |q| large. To prove that a solution homoclinic to zero e...
