Estimation of Source Location Using Curvature Analysis

A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...

Single Station Event Location: Epicentral Distance, Bearing, and Focal Depth

The most sensitive and reliable methods for locating small-magnitude regional seismic events using records from a single, three-component station require knowledge of the near-station and along-path crustal structure. Unfortunately, obtaining information about crustal structure is time-consuming and may be costly. Furthermore, different location methods may be required depending on the lateral ...

Polarization analysis on three-component seismic data

The acquisition of three-component high-density seismic data in WARR surveys, aimed at the two or three-dimensional modelling of buried structures, makes it possible to apply statistical-analysis techniques to estimate the propagation parameters of waves. The availability of the three components allows the use of the information about the state of the seismic wave polarization in order to filte...

Real-Time Estimation of Population Exposure to PM2.5 Using Mobile- and Station-Based Big Data.

Extremely high fine particulate matter (PM2.5) concentration has been a topic of special concern in recent years because of its important and sensitive relation with health risks. However, many previous PM2.5 exposure assessments have practical limitations, due to the assumption that population distribution or air pollution levels are spatially stationary and temporally constant and people move...

Low-Complexity Real-Time Single-Tone Phase and Frequency Estimation

This paper presents a low-complexity real-time single-tone phase and frequency estimation technique based on zero-crossing detection and linear regression. The proposed zerocrossing phase and frequency estimator fills a gap between lowcomplexity phase locked loop estimation and high-performance maximum likelihood estimation. Similar to a phase locked loop, the zero-crossing phase and frequency ...
