On multiple-parameter source localization

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002
Localization of multiple-parameter sources is considered in this paper. Specifically, the problem of localizing EEG polarized sources is addressed. Expressions are presented for the variance of the source parameter estimates for the MUSIC estimator. The expressions are presented for both finite sample effects and the model perturbations effects.

Source Parameters for Stick-Slip and for Earthquakes

Science, 1973
Source parameters of stick-slip friction events measured in the laboratory show particle and rupture propagation velocities which are similar to those observed for earthquakes and inferred from seismic source theory. This dynamic similarity strongly supports the idea that stick-slip is the mechanism for shallow earthquakes.

Parameter convergence in source localization

2016 IEEE Conference on Control Applications (CCA), 2016
A source localization problem which is nonlinear is converted to a structured-noise linear problem. An algorithm is proposed and its convergence has been established.

Analysis of glottal source parameters in Parkinsonian speech [PDF]

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Diagnosis and monitoring of Parkinson's disease has a number of challenges as there is no definitive biomarker despite the broad range of symptoms. Research is ongoing to produce objective measures that can either diagnose Parkinson's or act as an objective decision support tool.

Inversion for source levels and environmental and source track parameters

The Journal of the Acoustical Society of America, 2003
A methodology for simultaneous inversion for source levels, source track parameters, and environmental parameters is described. An application to acoustic data recorded on a bottom-mounted, horizontal line array at a soft-sediment, shallow-water site in the Gulf of Mexico off Port Aransas, TX is discussed.

Earthquake magnitude and source parameters

Bulletin of the Seismological Society of America, 1969
abstract Previous attempts to find empirical linear relationships between the magnitude, M, of an earthquake and the logarithm of one or more of the source parameters (length L, width W, displacement D) are reviewed. The fault parameters associated with a set of 27 earthquakes with strike-slip movement in the magnitude range 3.4 to 8.3 ...

Source Parameters and Their Determination

1979
A source of seismic waves (whether an earthquake or an explosion) is defined by the following parameters: 1. The latitude and longitude of the epicentre (i.e. the point on the earth’s surface located vertically above the source). 2. The depth of the source, or the focal depth (the source itself is called the focus or hypocentre).

Estimation of spatial and spectral parameters of multiple sources

IEEE Transactions on Information Theory, 1983
The problem of estimating spatial and spectral parameters of multiple sources by sensor arrays is considered. A parametric model is derived for the multichannel measurement vector. Tbe model parameters are the time delays and the autoregressive moving-average parameters of all the sources.

Effects of Poult Source on Turkey Production Parameters

Avian Diseases, 1991
Flock records from a commercial turkey company were analyzed to determine if poult source affected flock performance. Comparisons were made between flocks supplied by two hatcheries (X and Y) reared on the same farms and among flocks reared on different farms.
