Nonstationary Random Critical Excitation for Acceleration Response

Journal of Engineering Mechanics, 2001
The critical excitation method is promising as a robust method for accounting for inherent uncertainties in predicting forthcoming earthquake events and for constructing design earthquake ground motions in a reasonable way. Most of the proposed theories are based on deterministic approaches and deal with displacement responses.

A new probabilistic long-period critical excitation procedure for isolated building structures

Mechanics based design of structures and machines
The present paper develops a new procedure for finding the most unfavorable long-period excitation for isolated building structures based on the probabilistic critical excitation method.

Critical Bands and Excitation

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.

A Critical Comparison of Excitation Force Estimators for Wave-Energy Devices

IEEE Transactions on Control Systems Technology, 2020
The implementation of energy-maximizing control systems (EMCSs) can significantly increase the efficiency and economic viability of resonant wave-energy converters (WECs). To achieve optimal control and drive the WEC into resonance with the incoming wave

Critical Base Excitations of Structural Systems

Journal of Engineering Mechanics, 1991
A 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.

Critical excitation of sdof elasto-plastic systems

Journal of Sound and Vibration, 2006
Abstract The critical excitation of a dynamical system is defined as the input excitation with the lowest energy that drives the system from one specified state to another within a given time span. Critical excitations play an important role in first passage problems because they are the most probable point in the first passage failure region of the ...

Critical excitation function of distributed-parameter devices

IEEE Transactions on Electron Devices, 1966
A technique is described to estimate the transient response of thin-film devices at time intervals which exceed the greatest time constant or which are exceeded by the smallest time constant of the device. Relevant properties of distributed-parameter network functions are evaluated by applying the extreme value limit theorem to the corresponding ...

Critical-incidence coupling to intersubband excitations

Solid State Communications, 1994
Abstract For infrared spectroscopy of low-dimensional electron systems we suggest a geometry of critical-angle total internal reflection. An external polarizer then allows one to orient the electric field at the interface either parallel or perpendicular to the growth plane.
