NON-STATIONARY RESPONSE ANALYSIS OF DYNAMIC STRUCTURAL SYSTEMS

analysis on response of dynamic systems to pulse sequences excitation

near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. these pulse-type ground motions can be represented by pulse sequences with simple shapes. half-sinusoidal pulse sequences are used to approximate recorded ground motions and dynamic responses of sdof system under the excitation of these pulse sequences are studied. four cases are consi...

Sample-Path Stability of Non-Stationary Dynamic Economic Systems

The goal of this paper is to introduce and illustrate a new approach to the stability analysis of sample-paths of nonlinear stochastic economic models with non-stationary components. We place our study within the mathematical theory of random dynamical systems and apply the concept of a random fixed point which is tailor-made for the study of the long-term behavior of sample-paths in stochastic...

Monitoring of Non Stationary Systems Using Dynamic Pattern Recognition

The monitoring of non stationary systems permit to follow online the evolutions and changes which occur in the course of time. In Pattern Recognition (PR) the functioning modes are represented by a set of similar patterns, called classes. These patterns are obtained by observation of the most informative parameters of the system. To realize the monitoring of a system functioning PR methods uses...
