One of the best vibration control methods using smart actuators are semi-active approaches which are as strong as active methods and need no external energy supply such as passive ones. Compared with piezoelectric-based, magnetostrictive-based control methods have higher coupling efficiency, higher Curie temperature, higher flexibility to be integrated with curved structures and no depolarizati...

In recent years, there has been a growing recognition that the rocking motion of structures, especially cylindrical ones, should be evaluated with three-dimensional (3D) models. However, dissipation mechanisms in 3D models are complex and have yet to well established. This paper presents an analytical study on inherent mechanism based rolling friction model external energy dissipators (EDs) for...

Long-span bridges, as vital structures, play a very important role in economic development. Furthermore, the results of several earthquake-damaged bridges showed that their seismic behavior was different from that predicted under uniform excitation and in some cases the responses were more than predicted results. Therefore, the damaged bridges under non-uniform excitations were re-analyzed and ...

Given a fully extended topological quantum field theory, the “crossing with circle” conditions establish that dimension, or categorification thereof, of invariant assigned to closed k-manifold Σ is equivalent ( k + 1)-manifold [Formula: see text]. We compute in this paper these for 4-3-2-1 Dijkgraaf–Witten theory. In context lattice Hamiltonian realization invariants circle and torus encode def...

We study the nonequilibrium response of a $4\ifmmode\times\else\texttimes\fi{}3$ Hubbard model at $U=8$ under influence short electric field pulse, with main focus on multiple photon excitations and change double occupancy after pulse. The behavior mainly depends driving frequency field. largest occurs during For frequencies below Mott gap, we observe multiphoton large intensities. beyond gap e...

We estimate internal parameters of a Q-switched CO2 laser by fitting trajectories of the four-level model to measured scalar time series. The four-level model is a five-dimensional nonlinear system of ordinary differential equations. A multiple shooting technique is used to construct the unobserved time courses of the population densities and to reveal the dependence of the parameters on the ex...

We examine the stability of a class of solitons, obtained from a generalization of the Boussinesq equation, which have been proposed to be relevant for pulse propagation in biomembranes and nerves. These solitons are found to be stable with respect to small-amplitude fluctuations. They emerge naturally from non-solitonic initial excitations and are robust in the presence of dissipation. Solitar...
