This paper presents a new concept for an integrated structural health monitoring (SHM) system and its potential use in seismic application. The integrated SHM system incorporates sensor data compression, interactive data retrieval and structural system identification to address the challenging issues arising from current SHM practice. Since rapid data analysis is highly desired during or immedi...
Under certain theoretical assumptions, the theory of seismic interferometry allows the construction of artificial (or virtual) sources and receivers at the locations of receivers in a physical experiment. This is done by redatuming the physical sources to be at the locations of the physical receivers. Each redatumed trace is formed by stacking the cross-correlations of appropriate recorded trac...
A compact tilt accelerometer with high sensitivity at low frequency was designed to provide low frequency corrections for the feedback signal of the Advanced Laser Interferometer Gravitational Wave Observatory active seismic attenuation system. It has been developed using a Tungsten Carbide ceramic knife-edge hinge designed to avoid the mechanical 1/f noise believed to be intrinsic in polycryst...
natural signals are continues, therefore, digitizing is an essential task enabling us to use computing tools to process them. according to the nyquist/shannon sampling theory, the sampling frequency must be at least twice the maximum frequency contained in the signal which is being sampled; otherwise, some high frequencies may be aliased and result in a bad reconstruction. the nyquist sampling ...
abstract this research is about a longitudinal case study of english morpheme acquisition by a persian speaking child l2 learner of english (2 .9-3).the goal of this research has been discovery of the child ‘s ability in acquiring of english morphemes in a persian context while only one person (the child’ s father)has been talking to her.this child has also been exposed to english languag...
A large scale hydraulic injection was conducted at the Australian Hot Dry Rock site in November and December, 2003 in order to develop a commercial size underground heat exchanger. A Japanese seismic team set up the seismic network and data acquisition system, and carried out microseismic monitoring during the period in co-operation with the Australian teams. On-site analysis was done as an alm...
Among the technologies developed by NASA for space exploration, the TETwalker robot is one of the latest. NASA/Goddard Space Flight Center and CReSIS (Center of Remote Sensing of Ice Sheets) are proposing to adapt this technology for polar seismic data acquisition. In this paper, we discuss the design process for this project, explaining in detail each of the models created. This document summa...
