Estimating the accuracy of source “parameters”

Bulletin of the Seismological Society of America, 1967
abstract This paper suggests a method for estimating the errors accompanying estimates of seismic source parameters. While the method is a general one, the data here are from 1962 and 1963 and special attention is given to a few regions, such as the Kuriles.

A robust and efficient algorithm for source parameter estimation

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
A large number of array processing applications such as radar, sonar, etc. require the estimation of some parameters given the output of an array of sensors. Many high resolution methods for source parameter estimation are based on the eigen decomposition of the covariance matrix of the sensor output.

Love Waves and the Parameters of the Source

1967
In this chapter we investigate the possibility of determining, by observations on Love waves, the following source parameters: the depth of focus (principally within the boundaries of the crust) — according to the spectra of these waves; the magnitude — according to the amplitudes at various epicentral distances; and the mechanism — according to the ...

Test of Source-Parameter Inversion of Intensity Data

Natural Hazards, 2001
We demonstrate that the approximate source kinematics of the San Fernando, 1971 earthquake can be back-predicted by analysing its macroseismic intensity data set (felt reports) objectively and quantitatively. This is done by inverting either the data set of the intensity values observed in all sites, or the intensities tessellated with the Voronoi ...

Semi-blind source parameter separation

1997
Independent Component Analysis (ICA) is a useful extension of standard Principal Component Analysis (PCA). The ICA model is utilized mainly in blind separation of unknown source signals from their linear mixtures. In some applications, the mixture coefficients are totally unknown, while some knowledge about temporal model exists.

Study on the parameters for the convergence of the Method of Auxiliary Sources

2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC), 2019
The purpose of this paper is a rigorous accuracy analysis of the parameters affecting the solution convergence of the method of auxiliary sources (MAS). This study concerns the electromagnetic scattering of a transverse wave by a perfectly conducting, infinite, cylinder with an arbitrary shape.

Parameter estimation with multiple sources and levels of uncertainties

IEEE Transactions on Signal Processing, 2000
Summary: Least-squares designs are sensitive to errors in the data, which can be due to several factors including the approximation of complex models by simpler ones, the presence of unavoidable experimental errors when collecting data, or even due to unknown or unmodeled effects.

VARIABLE PARAMETER POWER SOURCE

1967
Abstract : A variable parameter power source was designed and fabricated to provide a 30-kva 3-phase source of power with controllable voltage modulation, frequency modulation and harmonic content for the purpose of simulating these power characteristics as described in MIL-STD-704.

Detection and parameter estimation of multiple radioactive sources

2007 10th International Conference on Information Fusion, 2007
Given an area where an unknown number of unaccounted radioactive sources potentially exist, and using gamma- radiation count measurements collected at known locations within this area, the problem is to estimate the number of sources as well as their locations and intensities. Two approaches are investigated.
