Coherent processing of regional signals at small seismic arrays
Autor: Zoltan A. Der, R. H. Shumway, M. R. Hirano
Publikováno v: Bulletin of the Seismological Society of America. 80:2161-2176
Regional arrivals, similarly to short-period teleseismic P waves, have a spectral structure that the Fourier transforms of individual sensors at arrays for events located in limited source regions can be decomposed into source and site spectral facto

Distributed lag regression by an almost periodic design matrix
Autor: M. J. Katzoff, R. H. Shumway
Publikováno v: Journal of Applied Probability. 15:759-773
Frequency domain estimation and tests of hypotheses are considered for a general multivariate distributed lag regression model. The usual vector of regression functions is replaced by a matrix of almost periodic functions, a case for which the terms

Linear spatial interpolation: Analysis with an application to San Joaquin Valley
Autor: William W.-G. Yeh, R. H. Shumway, Hugo A. Loáiciga
Publikováno v: Stochastic Hydrology and Hydraulics. 2:113-136
The properties of linear spatial interpolators of single realizations and trend components of regionalized variables are examined in this work. In the case of the single realization estimator explicit and exact expressions for the weighting vector an

Two methods to improve location estimates—preliminary results
Autor: R. H. Shumway, R. R. Blandford, B. W. Barker, A. C. Chang
Publikováno v: Bulletin of the Seismological Society of America. 73:281-295
Preliminary test results of two new seismic epicenter location methods show that the methods are quite effective in reducing location errors.The first method assumes that a large part of the travel-time residuals is caused by differences between the

Two-Dimensional Spectral Analysis of Soil Surface Temperature
Autor: M. Bazza, D. R. Nielsen, R. H. Shumway
Publikováno v: Hilgardia. 56:1-28
Soil surface temperature, measured on a 36-by-64 regular grid in a 6-hectare field, is modeled using two-dimensional spectral analysis and a signal-detection procedure. Temperature is found to behave randomly in one direction of the field (width), wh
