Small deviation probability via chaining

open access: yesStochastic Processes and their Applications, 2008
We obtain several extensions of Talagrand's lower bound for the small deviation probability using metric entropy. For Gaussian processes, our investigations are focused on processes with sub-polynomial and, respectively, exponential behaviour of covering numbers.

Study on the Horizontal Axis Deviation of a Small Radius TBM Tunnel Based on Winkler Foundation Model

open access: yesApplied Sciences, 2020
During the construction stage of the small radius TBM (tunnel boring machine) interval, the improper control of the boring parameters and the boring posture can cause the horizontal axis deviation of the shield tunnel. In order to address this issue, the

An Increase of GNSS Data Time Rate and Analysis of the Carrier Phase Spectrum

open access: yesRemote Sensing, 2023
Natural hazards and geomagnetic disturbances can generate a combination of atmospheric and ionospheric waves of different scales. The carrier phase of signals of global navigation satellite system (GNSS) can provide the highest efficiency to detect and ...

Integral representation with respect to fractional Brownian motion under a log-Hölder assumption

open access: yesModern Stochastics: Theory and Applications, 2015
We show that if a random variable is the final value of an adapted log-Hölder continuous process, then it can be represented as a stochastic integral with respect to a fractional Brownian motion with adapted integrand.

On Large Deviations for Small Noise Itô Processes [PDF]

open access: yesAdvances in Applied Probability, 2014
The large deviation principle in the small noise limit is derived for solutions of possibly degenerate Itô stochastic differential equations with predictable coefficients, which may also depend on the large deviation parameter. The result is established under mild assumptions using the Dupuis-Ellis weak convergence approach.
