Abstract: Abstract This paper addresses the tracking control problem of unmanned underwater vehicles under the condition of external disturbances and unmodeled dynamics using Port-Hamiltonian theory. By introducing Port-Hamiltonian theory, conventional UUVs dynamics can be transformed into… read more here.

DOI: 10.1103/physrevd.101.123531
Abstract: We derive a Hamiltonian formulation of the theory of gauge invariant, linear perturbations in anisotropic Bianchi I spacetimes, and describe how to quantize this system. The matter content is assumed to be a minimally coupled… read more here.
