Correlated z-values and the accuracy of large-scale statistical estimates
large-scale statistical estimates Correlated z-values
2015/8/20
We consider large-scale studies in which there are hundreds or thousands of correlated cases to investigate, each represented by its own normal variate, typically a
z-value. A familiar example is pro...
Limits on the potential accuracy of earthquake risk evaluations using the L’Aquila (Italy) earthquake as an example
earthquake risk evaluations earthquake
2015/8/17
This article is concerned with attempting to ‘predict’ (hindcast) the
damage caused by the L’Aquila 2009 earthquake (Mw 6.3) and, more
generally, with the question of how close predicted damage can ...

Precision tao points function and convex agent convex optimization problem function hypothesis set
2015/8/7
We introduce a new notion of classification accuracy based on the top tau-quantile values of a scoring function, a relevant criterion in a number of problems arising for search engines. We de...

Spectral Calibration Sensor Pollution
2015/7/29
Several applications for the examination of plants by use of hand-held spectrometers exist in the field of environmental monitoring
and precision agriculture. Portable instruments render possible th...
A Proof of the Stability of the Spectral Difference Method for All Orders of Accuracy
Spectral Difference Method Accuracy
2015/6/23
One of the most promising approaches is the
Discontinuous Galerkin (DG) method, for which the theoretical basis has been provided in
a series of papers by Cockburn and Shu [1, 2, 3, 4]. The rapid gr...
Assessing accuracy of gas-driven permeability measurements: a comparative study of diverse Hassler-cell and probe permeameter devices
gas-driven permeability measurements diverse Hassler-cell probe permeameter devices
2015/1/6
Permeability is one of the most important petrophysical parameters to describe the reservoir properties of sedimentary rocks, pertaining to problems in hydrology, geothermics, and hydrocarbon reservoi...

2012/11/23
Typical cohorts in brain imaging studies are not large enough for systematic testing of all the information contained in the images. To build testable working hypotheses, investigators thus rely on an...
Accuracy of Classical Conservation Laws for Hamilton PDES Under Runge-Kutta Discretizations
Accuracy of Classical Conservation Laws Hamilton PDES Runge-Kutta Discretizations
2012/8/7
We investigate conservative properties of Runge-Kutta methods
for Hamiltonian PDEs. It is shown that multi-symplecitic Runge-Kutta meth-
ods preserve precisely norm square conservation law. Based on...
