Using the (Iterative) Ensemble Kalman Smoother to Estimate the Time Correlation in Model Error
Numerical weather prediction systems contain model errors related to missing and simplified physical processes, and limited model resolution. While it has been widely recognized that these model errors need to be included in the data assimilation ...

A neutrosophic student’s t –type of statistic for AR (1) random processes [PDF]
Neutrosophic statistics are used when one is dealing with imprecise and indeterminate data or parameters. In the present paper we propose a method for performing a neutrosophic Student’s t –type of statistical test that concerns the population mean when ...

Confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature
Laser speckle imaging has been widely used for in-vivo visualization of blood perfusion in biological tissues. However, existing laser speckle imaging techniques suffer from limited quantification accuracy and spatial resolution.

Alternative Interpretation of Speckle Autocorrelation Imaging Through Scattering Media
High-resolution optical imaging through or within thick scattering media is a long sought after yet unreached goal. In the past decade, the thriving technique developments in wavefront measurement and manipulation do not significantly push the boundary ...

Statistical analysis of vegetable productivity dynamics of Uzbekistan [PDF]
In all fields, there are a lot of random events at a given time. In particular, the process of growing agricultural crops, which is repeated over a certain period, that is, seasonally, is the basis for our analysis as a discrete {Yt,t ∈ T} random dynamic

Decay of distance autocorrelation and Lyapunov exponents [PDF]
This work presents numerical evidences that for discrete dynamical systems with one positive Lyapunov exponent the decay of the distance autocorrelation is always related to the Lyapunov exponent.
