Interim Report on Capabilities of the Experimental Large Aperture Seismic Array
نویسندگان
چکیده
This report presents an interim appraisal of capabilities of a single Large Aperture Seismic Array system to perform the following functions: (i) preprocess arriving seismic signals to increase their detectability, (ii) use such preprocessed signals to perform on-line automatic detection and location, (iii) process recordings of LASA data off-line, and (iv) use the results of the off-line processing for studies of seismic source type.

Large Aperture Seismic Array Capabilities
This report presents the results of a study of the effectiveness of the experimental Large Aperture Seismic Array in Montana. An attempt has been made, where possible, to draw conclusions from the study of this one station about the performance that might be expected from a worldwide net of several of them. The report discusses the reliability and continuity of observations obtainable from a LA...
متن کاملGeometry and Patterns of Large Aperture Seismic Arrays
A study of possible configurations for a Large Aperture Seismic Array has been completed. An array having 21 identical subarrays located on three concentric circles has been found to yield the most satisfactory pattern in wave number space of all the configurations tested. Patterns for some alternative placements of subarrays, including that of the experimental LASA in Montana, have been includ...
متن کاملTracking sperm whale (Physeter macrocephalus) dive profiles using a towed passive acoustic array.
A passive acoustic method is presented for tracking sperm whale dive profiles, using two or three hydrophones deployed as either a vertical or large-aperture towed array. The relative arrival times between the direct and surface-reflected acoustic paths are used to obtain the ranges and depths of animals with respect to the array, provided that the hydrophone depths are independently measured. ...
متن کاملHigh throughput optical lithography by scanning a massive array of bowtie aperture antennas at near-field
Optical lithography, the enabling process for defining features, has been widely used in semiconductor industry and many other nanotechnology applications. Advances of nanotechnology require developments of high-throughput optical lithography capabilities to overcome the optical diffraction limit and meet the ever-decreasing device dimensions. We report our recent experimental advancements to s...
متن کاملMolecular Dissection Using Array Comparative Genomic Hybridization and Clinical Evaluation of An Infertile Male Carrier of An Unbalanced Y;21 Translocation: A Case Report and Review of The Literature
Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated wi...
