Statistical Monitoring of Rare Events in Healthcare
There are miscellaneous quality characteristics in healthcare which are interested to be monitored. However, monitoring each characteristic needs a special statistical method. There are some characteristics with very small incidence rates that it’s usually considered not to be necessary to monitoring them, since their incidence rates are so small that p and np charts are not able to monitor t...
متن کاملRare Events for Statistical Model Checking an Overview
This invited paper surveys several simulation-based approaches to compute the probability of rare bugs in complex systems. The paper also describes how those techniques can be implemented in the professional toolset Plasma.
متن کاملFracture Dynamic Propagation Model of High-Energy Gas Fracturing for Casing Perforated Well
The onshore oil and natural gas industries of China have started a large-scale development when crude oil reserves have been difficult to recover. The stratum fracture modification is an indispensable measure to efficiently develop oil and gas fields. Hydraulic fracturing is the most important reservoir stimulation technique, but it is still faced with various problems such as the failure to fr...
متن کاملParticle Physics Explanations for Ultra High Energy Cosmic Ray Events
The origin of cosmic ray events with E ∼ 10 11 GeV remains mysterious. In this talk I briefly summarize several proposed particle physics explanations: a breakdown of Lorentz invariance, the “Z−burst” scenario, new hadrons with masses of several GeV as primaries, and magnetic monopoles with mass below 10 GeV as primaries. I then describe in a little more detail the idea that these events are du...
متن کاملStatistical Learning in High Energy and Astrophysics
This thesis studies the performance of statistical learning methods in high energy and astrophysics where they have become a standard tool in physics analysis. They are used to perform complex classification or regression by intelligent pattern recognition. This kind of artificial intelligence is achieved by the principle “learning from examples”: The examples describe the relationship between ...
