Thereby, they deal with a random excitation by a non-white Gaussian stochastic process.They formulate the pendulum energy converter as a weakly perturbed Hamiltonian system. The random process across the energy levels of the Hamiltonian system is then approximated by a Markov process, which is obtained by stochastic averaging. This procedure leads to analytical results for the energy of the pendulum motion, which are used for analyzing the required probability of reaching higher energy states of the pendulum energy converter in order to maximize the harvested energy.

Metrikine Derivation and veriﬁcation of a lattice model for bending vibration of a plate Lattice models are successfully used in modelling of fracture of brittle materials. To date, most of the lattice multidimensional (2D and 3D) models known to the authors describe either in-plane or three-dimensional mechanics of the
