Estimation of the Tapered Gutenberg-Richter Distribution Parameters for Catalogs with Variable Completeness: An Application to the Atlantic Ridge Seismicity

open access: yesApplied Sciences, 2021
The use of the tapered Gutenberg-Richter distribution in earthquake source models is rapidly increasing, allowing overcoming the definition of a hard threshold for the maximum magnitude.

Distribution of b-value in the central and southern Ryukyu: is the low b-value in the rift-axis of the Okinawa Trough accurate?

open access: yesEarth, Planets and Space, 2022
Here, I investigated whether the b-value in the rift-axis of the Okinawa Trough, a back-arc basin, is low. The cause of the low b-value in the rift-axis of the Okinawa Trough had previously been interpreted as increased stress by dyke intrusion. However,

Estimating the Magnitude of Completeness of Earthquake Catalogs Using a Simple Random Variable Transformation

open access: yesThe Seismic Record, 2023
The estimation of the magnitude of completeness for a seismic catalog is the starting point for most of the seismological statistical analyses. It is important, in particular, for the estimation of the Gutenberg–Richter (GR) law parameters.

A ROSAT Survey of a Spatially and Magnitude Complete Quasar Sample [PDF]

open access: yesSymposium - International Astronomical Union, 1994
The field studied is part of the Hamburg Quasar Survey (Engels et al. 1988, PASPC 2, 143). It contains a spatially and magnitude (down to ∼ 18.m5) complete AGN sample. Several follow-up observations were made: a deep radio continuum survey at 21 cm and 74 cm, a HI survey and a ROSAT survey consisting of 48 overlapping PSPC pointings with .

A modal logic for reasoning on consistency and completeness of regulations [PDF]

open access: yes, 2009
In this paper, we deal with regulations that may exist in multi-agent systems in order to regulate agent behaviour and we discuss two properties of regulations, that is consistency and completeness.

A simple tool for assessing the completeness in apparent magnitude of magnitude-redshift samples [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2001
A new tool is proposed for finding out the completeness limit in apparent magnitude of a magnitude-redshift sample. The technique, closely related to the statistical test proposed by Efron & Petrosian (1992), presents a real improvement compared to standard completeness tests.

Data Completeness in Healthcare: A Literature Survey [PDF]

open access: yes, 2017
As the adoption of eHealth has made it easier to access and aggregate healthcare data, there has been growing application for clinical decisions, health services planning, and public health monitoring with daily collected data in clinical care.
