Consider the following stochastic switched nonlinear system dx(t)=[fi(x)+li(x)v(t)]dt+gi(x)dω(t),y(t)=hi(x), where i∈I={1,2}, ω is a standard Wiener process, and f1(x)=(−2x1−34x13−4x2−52x23),l1(x)=(−12x1−x2),g1(x)=(12x12−x22−12x12+x22...
This paper develops an improved remaining useful life (RUL) prediction method for bearings based on a nonlinear Wiener process model. First, the service life of bearings is divided into two stages in terms of the working condition. Then a new prognostic model is constructed to reflect the ...
This paper presents a model based on a bivariate Wiener process in which one component represents the marker and the second, which is latent (unobservable), determines the failure time. In particular, failure occurs when the latent component crosses a threshold level. The model yields reasonably ...
Aiming at this problem, an RUL prediction method based on the consistency test of a Wiener process is proposed. Firstly, the parameters of the Wiener process estimated by Maximum Likelihood Estimation (MLE) are proved to be biased, and a modified unbiased estimation method is proposed and ...
In contrast, we considered a non-Wiener process which has biologically more relevant properties, at least in the context of the individual animal movement. We showed that it results in a more general model, which includes the standard Langevin equation (i.e. with Wiener noise) and the ...
We prove existence and uniqueness theorems for a solution to a stochastic Volterra equation on the plane. The proofs employ an inequality for a stochastic integral with respect to a two-parameter Wiener process, where the integrand depends on the limits of integration.关键词: two-parameter Wiener...
Let L be an nth order linear differential operator with smooth coefficients and {W(t) : t ∈ [0, 1]} a standard Wiener process. We consider the stochastic differential equation A Alabert,M Ferrante - Birkhäuser Boston 被引量: 5发表: 1998年 VariationalApproachfortheAdaptedSolutionofBackward...
Wiener process is widely used for its mathematical tractability and flexibility. These models are described by a stochastic differential equation of the following typedYt=(−τYt+μ)dt+Σ(Yt)dWt,Y0=y0,where {Wt}t≥ 0is a standard Wiener process,Y0=y0is the initial condition,τ>0,μ∈...
(with 900 trials per position). Error bars give the standard error of the mean. Example stimuli are shown at the bottom.g, In our model, the VAE increases the estimated size of the central object in atypically ‘zoomed out’ views compared with the training data, and decreases it in ...
