Maximum Magnitude of Completeness in a Salt Mine [PDF]

Bulletin of the Seismological Society of America, 2015
Abstract In this study, we analyze acoustic emission (AE) data recorded at the Morsleben salt mine, Germany, to assess the catalog completeness, which plays an important role in any seismicity analysis. We introduce the new concept of a magnitude completeness interval consisting of a maximum magnitude of completeness ( M c(max) ) in addition to the ...

On the Magnitude of Completeness Thresholds in Bounded Model Checking

2012 27th Annual IEEE Symposium on Logic in Computer Science, 2012
Bounded model checking (BMC) is a highly successful bug-finding method that examines paths of bounded length for violations of a given regular or omega-regular specification. A completeness threshold for a given model M and specification phi is a bound k such that, if no counterexample to phi of length k or less can be found in M, then M in fact ...

A Homogeneous Earthquake Catalog for Western Turkey and Magnitude of Completeness Determination

Bulletin of the Seismological Society of America, 2013
Abstract A catalog for earthquakes that occurred in western Turkey during the period 1964–2010 is compiled for achieving homogeneity for magnitudes. Data are obtained from the International Seismological Center (ISC), where earthquake magnitudes are reported in different scales and come from a variety of sources.

Quantifying the Impact of Declustering Techniques on Completeness Magnitude Estimation

Bulletin of the Seismological Society of America
ABSTRACT Seismicity analysis and earthquake hazard assessment require catalogs of independent events and accurate estimates of completeness. The magnitude of completeness (Mc) defines the threshold below which earthquakes are likely to be missed; declustering, used to remove dependent events, can substantially alter Mc by reshaping ...

Bayesian Estimation of the Spatially Varying Completeness Magnitude of Earthquake Catalogs

Bulletin of the Seismological Society of America, 2011

Completeness - II. A signal-to-noise ratio approach for completeness estimators applied to galaxy magnitude-redshift surveys [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
This is the second paper in our completeness series, which addresses some of the issues raised in the previous article by Johnston, Teodoro & Hendry, in which we developed statistical tests for assessing the completeness in apparent magnitude of ...

Counts of Quasars at Faint Magnitudes: A New Complete Sample [PDF]

Symposium - International Astronomical Union, 1986
We present results on a new sample of optically selected quasar candidates. The “standard” multicolor technique for selecting quasar candidates has been applied to all the objects brighter than J = 22.0 in a field of 0.69 square degrees. Additional candidates have been selected from a search on grism plates obtained in the same area.
