Statistical zone finding
We propose a statistical technique of zone finding for the class of documents that are neither rigidly structured like tax forms nor very unstructured like magazine pages or engineering drawings. Given an initial window assumed to contain the final zone (bounding box) of interest, and a ‘signature’ of the target, we propose to locate the final zone by a combination of simple outside in and insi...
متن کاملThe spatial density of foreshocks
[1] Aftershocks follow a well‐defined spatial decay pattern in the intermediate field. Here I investigate the same pattern for foreshocks. Foreshock linear density decays as r over distances r of 0.1–30 km for 15 minutes before magnitude 3–4 mainshocks. This trend is the same as that of the aftershocks within the error of the measurement. This consistency of spatial decay can be explained by th...
متن کاملPrediction Probabilities From Foreshocks
When any earthquake occurs, the possibility that it might be a foreshock increases the probability that a larger earthquake will occur nearby within the next few days. Clearly, the probability of a very large earthquake ought to be higher if the candidate foreshock were on or near a fault capable of producing that very large mainshock, especially if the fault is towards the end of its seismic c...
متن کاملFirst Finding of Satin Spar Gemstone in Iran, Folded Zagros Zone, Fars Region
The gypsum mineralization occurred in the form of Satin Spar and Selenite in the south and southwest of the Fars province in the folded Zagros zone. In this region, Satin Spar mineralization has been formed as stratiform between the red marl and siltstone units of Late Miocene–Pliocene in Agha Jari, Bakhtiari, and the Gachsaran formations. The reserves of Satin Spar in this area are at least 20...
متن کاملApplying behavioural science to government policy: Finding the ‘Goldilocks Zone’
Using behavioural and social science to inform government policy has the potential to benefit society – provided good scientific practice is adopted. We argue that there are threats to scientific practice in the current Behavioural Insights environment that potentially undermine the validity and usefulness of such work. We discuss what constitutes good science and why this is important, and exa...
