Nonspecular meteor trail altitude distributions and durations observed by a 50 MHz high‐power radar
durations observed trail altitude distributions
2017/3/22
High‐power large‐aperture (HPLA) radars frequently observe nonspecular meteor trail
echoes that result from plasma turbulence driven by the intense pressure gradients on
the trail edges. This paper ...
Fractal dimension confidence interval estimation of epicentral distributions
correlation dimension confidence interval seismicity
2015/9/30
Estimates of the fractal dimension of hypocentral distributions require evaluating the range of independent variables in which fractal parameters exhibit a power law. Systematic and accidental errors ...
Modelling complex geological circular data with the projected normal distribution and mixtures of von Mises distributions
Circulation data earth science statistical description structural geology circulation data set
2015/1/6
Circular data are commonly encountered in the earth sciences and statistical descriptions and inferences about such data are necessary in structural geology. In this paper we compare two statistical d...
Can vesicle size distributions assess eruption intensity during volcanic activity?
volcanic activity vesicle size
2015/1/5
We studied three-dimensional (3-D) vesicle size
distributions by X-ray microtomography in scoria collected
during the relatively quiescent Phase II of the April–May
2010 eruption at Eyjafjallaj...
Particle size distributions by laser diffraction: sensitivity of granular matter strength to analytical operating procedures
Particle size distributions laser diffraction granular matter strength analytical operating procedures
2014/12/31
We tested laser diffraction particle size analysis in poorly coherent carbonate platform cataclastic breccias and unfaulted quartz-rich eolian sands, representing low- and high-strength granular mater...
Statistical properties of galaxy distributions
Statistical properties galaxy distributions
2009/11/16
The recent availability of complete three dimensional samples of galaxies and clusters permits a direct study of their spatial properties. We present a brief review of galaxy correlations based on the...
Theory of localized bipolar wave-structures and nonthermal particle distributions in the auroral ionosphere
localized bipolar wave-structures nonthermal particle distributions auroral ionosphere
2009/11/13
Bipolar wave structures and nonthermal particle distributions measured by the FAST satellite in regions of downward current are interpreted in terms of the nonlinear evolution of a two-stream instabil...
A nonextensive entropy path to probability distributions in solar wind turbulence
nonextensive entropy path probability distributions solar wind turbulence
2009/11/9
The observed scale dependence of the probability distributions of the differences of characteristic solar wind variables is analyzed. Intermittency of the turbulent fluctuations at small-scale spatial...
Probability distributions of landslide volumes
Probability distributions landslide volumes
2009/10/30
We examine 19 datasets with measurements of landslide volume, VL, for sub-aerial, submarine, and extraterrestrial mass movements. Individual datasets include from 17 to 1019 landslides of different ty...
Information theoretic measures of dependence,compactness,and non-gaussianity for multivariate probability distributions
Information theoretic measures non-gaussianity multivariate probability distributions
2009/10/30
A basic task of exploratory data analysis is the characterisation of "structure" in multivariate datasets. For bivariate Gaussian distributions, natural measures of dependence (the predictive relation...
Probability Distributions of CO2-induced Global Warming as Inferred Directly from Multimodel Ensemble Simulations
climate change global warming probability distribution
2009/6/9
Analytical, purely model-based probability distributions are derived for the instantaneous global mean warming resulting from a gradual doubling of CO2 (TCR = transient climate response) and for the e...
Statistical evaluation of characteristic earthquakes in the frequencymagnitude distributions of Sumatra and other subduction zone regions
Statistical evaluation characteristic earthquakes the frequencymagnitude distributions of Sumatra other subduction zone regions
2014/5/19
If subduction zone earthquakes conform to a characteristic model, in which persistent segments fail at predictable stress levels due to the steady accumulation of tectonic loading, historical seismici...
Analytical expressions and distributions of gravity anomalies caused by model bodies with a polygonal shaped horizontal cross section
gravity model body spectrum
2009/3/5
We can find many polygonal gravity anomalies in the gravity map series (1 : 200,000) published by Geological Survey of Japan, AIST. To analyze these gravity anomalies, the authors reviewed the computi...
Analytical expressions and distributions of vertical gradient of gravity caused by model bodies symmetry with respect to a vertical axis, and characteristics of these maps
gravity model body vertical gradient
2009/3/4
We can find many symmetrical gravity anomalies such as center point symmetry in the gravity map series (1 : 200,000) published by Geological survey of Japan, AIST. To analyze these gravity anomalies, ...
