The long-term goal of the present high-frequency scattering statistics work is to examine the links between environmental parameters of shallow water boundaries and the statistics of high frequency, broadband acoustic fields using a combination of at-sea measurements, ground truth and theoretical modeling. The influence of the properties of the boundaries to the scattered envelope statistics an...

In this article we emphasize the manner in which this statistical indicator the variation coefficient (v) could help the inference on measurable characteristics generated by technological processes. Our interest lies upon the so-called SPCStatistical Process Control; the main result obtained is the following: if the coefficient of variation is known, then the statistical distribution of capabil...

We present research in progress, aimed at explaining the tradeoffs between vegetative and reproductive structures in the architecture of Protea. The species of interest, Protea lepido-carpodendron, reproduces only after a fire that kills it. We aim at using a biomechanical developmental functionalstructural model to demonstrate that Protea lepidocarpodendron is adapted to the statistical distri...

Cortical activity involves large populations of neurons, even when it is limited to functionally coherent areas. Electrophysiological recordings, on the other hand, involve comparatively small neural ensembles, even when modern-day techniques are used. Here we review results which have started to fill the gap between these two scales of inquiry, by shedding light on the statistical distribution...

This paper analyses the statistical distribution of war sizes. Using the method recently proposed by Clauset, Shalizi, and Newman (2009), we find moderate support for a Pareto-type distribution (power law), using data from different sources (COW and UCDP) and periods. A power law accurately describes not only the size distribution of all wars, but also the distribution of the sample of wars in ...

Pyrosequencing is emerging as one of the important next-generation sequencing technologies. We derive the statistical distributions of this technique in terms of nucleotide probabilities of the target sequences. We give exact distributions both for fixed number of flow cycles and for fixed sequence length. Explicit formulas are derived for the mean and variance of these distributions. In both c...

In this work the use of statistical techniques will be approached for segmentation of SAR images, with the purpose of ship detection, being used RADARSAT images of the Brazilian coast. As described in Rocha et al (2001) and Rocha and Stech (2003), a specific software for ship detection was developed where, based on Eldhuset (1996), Vachon et al (1997), Oliver and Quegan (1998), Zaart et al (199...

The spectrum of the quasar Q0055-269 (z = 3:66) has been observed at the resolution of 14 km s 1 in the wavelength interval 4750{6300 A. We give a list of Lyman lines and metal-line systems for which column densities and Doppler widths have been derived by a tting procedure. The statistical distribution of the Doppler parameter for the Lyman lines is peaked at b ' 23 km s 1, with 13% of lines w...

We report on the study of unusual spin glass properties in the geometrically frustrated pyrochlore Tb(2)Mo(2)O(7), T(g) ~/= 24 K. The analysis of the nonlinear part of dc and complex susceptibilities, near the glass transition regime, suggests the existence of a statistical distribution of relaxation times in short-range ordered ferromagnetic clusters. In addition, the magnetic spins are not su...

In this study, we implemented a new method for measuring the temporal delay of functional magnetic resonance imaging (fMRI) responses and then estimated the statistical distribution of response delays evoked by visual stimuli (checkered annuli) within and across voxels in human visual cortex. We assessed delay variability among different cortical sites and between parenchyma and blood vessels. ...
