Optimal damper placement for critical excitation
Probabilistic Engineering Mechanics, 2000Since earthquake ground motions are very uncertain even with the present knowledge, it is desirable to develop a robust structural design method taking into account these uncertainties. Critical excitation approaches are promising and a new probabilistic critical excitation method is proposed. Different from the conventional critical excitation methods,

Critical excitation energy in fusion-evaporation reactions
Physical Review C, 1990The widths of the residue-mass distributions are used as a measure of the excitation energy of hot nuclei. They increase with the recoil velocity but saturate much below the calculated velocity {ital v}{sub CN} for complete fusion. Above these critical excitations energies (4.5--6.4 MeV/nucleon) derived from the recoil velocity, the normal evaporation ...

EXCITABLE NETWORKS: NONEQUILIBRIUM CRITICALITY AND OPTIMUM TOPOLOGY
International Journal of Bifurcation and Chaos, 2010Excitable media may be modeled as simple extensions of the Amari–Hopfield network with dynamic attractors. Some nodes chosen at random remain temporarily quiet, and some of the edges are switched off to adjust the network connectivity, while the weights of the other edges vary with activity.

The Critical Excitation of Nonlinear Systems
Journal of Applied Mechanics, 1977The critical excitation of a mechanical system, in the terminology of this paper, is one that drives the system to a larger response peak than any other in some class of allowed excitations. The critical excitation is of interest in questions related to the reliability and safety because the magnitude of the response peak is frequently an indicator of ...

1999
The concept of critical bands is introduced in this chapter, methods for determining their characteristics are explained, and the scale of critical-band rate is developed. The definitions of critical-band level and excitation level are given and the three-dimensional excitation level versus critical-band rate versus time pattern is illustrated.

Critical Base Excitations of Structural Systems
Journal of Engineering Mechanics, 1991A critical excitation is one that maximizes chosen response quantities subject to constraints related to duration and energy imposed on the excitation. A study of the response of single- and multi-degree-of-freedom systems subjected to critical base excitations is presented.
