Random Vibration Systems with Weakly Correlated Random Excitation

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001
AbstractIn the paper asymptotic expansions for second‐order moments of solutions to ordinary differential equations with weakly correlated random inhomogeneous terms are presented. Such equations arise e.g. in the mathematical modeling of vibration systems with an external random excitation.

Unified Stability Criteria of Random Nonlinear Time-Varying Impulsive Switched Systems

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2020
This paper investigates the problem of noise-to-state practical stability in mean (NSpS-M) (which is a natural generalization of noise-to-state stability in mean) and the problem of almost sure global asymptotic stability (GAS a.s.) for a class of random

A Survey of Random Forest Based Methods for Intrusion Detection Systems

ACM Computing Surveys, 2018
Over the past decades, researchers have been proposing different Intrusion Detection approaches to deal with the increasing number and complexity of threats for computer systems.

Random Dynamical Systems

2016
In this chapter we will introduce methods and techniques to analyze models with stochasticity or randomness. In particular we will establish the framework of random dynamical systems and introduce the concept of random attractors.

The Stress Tensor In Quenched Random Systems

, 2001
The talk describes recent progress in understanding the behavior of the Stress tensor and its correlation functions at a critical point of a generic quenched random system. The topics covered include: (i) the stress tensor in random systems considered as

Random Dynamical Systems

2007
This treatment provides an exposition of discrete time dynamic processes evolving over an infinite horizon. Chapter 1 reviews some mathematical results from the theory of deterministic dynamical systems, with particular emphasis on applications to economics. The theory of irreducible Markov processes, especially Markov chains, is surveyed in Chapter 2.

Wigner distribution for random systems

Journal of Modern Optics, 2002
We use the Wigner distribution to study systems subjected to random forces. We define the instantaneous spectrum as the ensemble average of the Wigner distribution, and we write the differential equation whose solution gives us the time-varying spectrum of the state variable. We consider the cases of both constant and time-varying coefficients.

Partial realization of random systems

Automatica, 1972
Abstract An algorithm is presented for the recursive determination of certain lumped linear models that when driven by a white-noise sequence yield outputs whose covariances match increasing sections of a given covariance sequence.

Random Independence Systems

1981
Abstract : This report introduces a new random structure generalizing matroids. These random independence systems allow us to develop general techniques for solving hard combinatorial optimization problems with random inputs.

Random Hyperbolic Systems

2007
We review definitions of random hyperbolic sets and introduce a characterization using random cones. Moreover we discuss problems connected with symbolic representations and the thermodynamic formalism for random hyperbolic systems both in discrete and continuous time cases.
