Block Estimation Technique in Spatial Statistics With Application

open access: yesTikrit Journal of Pure Science, 2023
This paper deals with the predictions of estimation mean of set  points (Block) at sub domain determined within domain study by one arithmetic process as if as this set of points is one point, and we used in this paper a technique called Block kriging ...

Extreme Events in Resonant Radiation from Three-dimensional Light Bullets [PDF]

open access: yes, 2014
We report measurements that show extreme events in the statistics of resonant radiation emitted from spatiotemporal light bullets. We trace the origin of these extreme events back to instabilities leading to steep gradients in the temporal profile of the

Spectral Methods in Spatial Statistics

open access: yesDiscrete Dynamics in Nature and Society, 2014
When the spatial location area increases becoming extremely large, it is very difficult, if not possible, to evaluate the covariance matrix determined by the set of location distance even for gridded stationary Gaussian process.

Nonparametric tests of structure for high angular resolution diffusion imaging in Q-space [PDF]

open access: yes, 2010
High angular resolution diffusion imaging data is the observed characteristic function for the local diffusion of water molecules in tissue. This data is used to infer structural information in brain imaging. Nonparametric scalar measures are proposed to

Optimal and fast detection of spatial clusters with scan statistics [PDF]

open access: yes, 2010
We consider the detection of multivariate spatial clusters in the Bernoulli model with $N$ locations, where the design distribution has weakly dependent marginals.

Is Forensic Entomology Lost in Space?

open access: yesInsects, 2021
Spatial and scale effects have barely been considered in forensic entomology, despite their pervasive influence on most of the parameters affecting the development of insect larval stages and the progression of insect succession on cadavers.

Natural ITD statistics predict human auditory spatial perception

open access: yeseLife, 2020
A neural code adapted to the statistical structure of sensory cues may optimize perception. We investigated whether interaural time difference (ITD) statistics inherent in natural acoustic scenes are parameters determining spatial discriminability.

Observation of Intensity Statistics of Light Transmitted Through 3D Random Media [PDF]

open access: yes, 2014
We experimentally observe the spatial intensity statistics of light transmitted through three-dimensional isotropic scattering media. The intensity distributions measured through layers consisting of zinc oxide nanoparticles differ significantly from the
