Holographic duality provides a description of strongly coupled quantum systems in terms weakly gravitational theories higher-dimensional space. It is challenge, however, to quantitatively determine the physical parameters corresponding generic holographic theories. Here, we address this problem for two-dimensional superfluid, known exhibit strong dissipation. We numerically simulate motion vort...

time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. one of the important issues in the time-history analysis is selecting earthquake records. in this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. a...

We apply the techniques of stochastic integration with respect to the fractional Brownian motion and the theory of regularity and supremum estimation for stochastic processes to study the maximum likelihood estimator (MLE) for the drift parameter of stochastic processes satisfying stochastic equations driven by fractional Brownian motion with any level of Hölder-regularity (any Hurst parameter)...

Let α, T > 0. We study the asymptotic properties of a least squares estimator for the parameter α of a fractional bridge defined as dXt = −α Xt T−t dt + dBt, 0 6 t < T , where B is a fractional Brownian motion of Hurst parameter H > 12 . Depending on the value of α, we prove that we may have strong consistency or not as t → T . When we have consistency, we obtain the rate of this convergence as...
