The experimental results show that:in comparison to the traditional equivalent linearization method,the new way given in this paper can solve non-linearity problem effectively,it can be widely applied in a variety of non-linearity system,and a non-linearity system analysis excited by random vibration signal is proceeded.
In the length of 107.30 m,about 59.3% of the space heterogeneity of the powder sand is caused by random factors,and 40.7% by the space autocorrelations and the rest space heterogeneity is rarely caused by random factors,but by space heterogeneity of autocorrelations.
The approach is to combine Random Decrement Technique with Polyreference MDOF Method. More than one set of free responses are obtained from stationary random responses of the structure by Random Decrement Technique.
(3) Fuzzy rough set model based on random set on dual universes is proposed. It gives a way to deal with the uncertainty problems that knowledge in knowledgebase is fuzzy and gained by random reasons, and the described object is also fuzzy.
We develop a method to estimate the power spectrum of a stochastic process on the sphere from data of limited geographical coverage.
This paper analyzes the aritrage-free security markets and the general equilibrium existence problem for a stochastic economy with incomplete financial markets.
This paper studies a stochastic endogenous growth model with pollution.
This paper deals with the problem of maximizing the expected utility of the terminal wealth when the stock price satisfies a stochastic differential equation with instantaneous rates of return modelled as an Ornstein-Uhlenbeck process.
A Stochastic Deterministic Model Predictive Control: Its Accuracy
This paper gives us a brief introduction to the complex channel analysis which aims at obtaining the dynamic parameters with the characteristics of surface seismology, such as transient amplitude, transient phase, transient frequency and apparent reflected polarity. It is of great significence either in interpreting the oil-gas reserves and obtaining the lithologic information.
In this paper, the random drift rates, sampled at equal time intervals, of a two-degree-of-freedom floated gyro are processed and analysed, employing 601 data points of random drift rates both about the horizontal axis and azimuth axis. In addition, the mathematical model of them is being identified roughly. The result of this investigation shows that:
On the basis of the set theory, a method for determining random samples of zero-up-crossing, monogamy of wave height and wave period, maxima and minima of surface wave obtained from a continuous observation of random surface waves is proposed.
