Field test of the superconducting gravimeter as a hydrologic sensor.
We report on a field test of a transportable version of a superconducting gravimeter (SG) intended for groundwater storage monitoring. The test was conducted over a 6-month period at a site adjacent to a well in the recharge zone of the karstic Edwards Aquifer, a major groundwater resource in central Texas. The purpose of the study was to assess requirements for unattended operation of the SG i...
متن کاملThe Superconducting Gravimeter as a Field Instrument Applied to Hydrology
We describe development of a transportable version of the Superconducting Gravimeter (SG) and its test in a field experiment to monitor storage in a karst (limestone) aquifer in central Texas. The SG is contained within two aluminum enclosures, one holding the SG in its 35 liter helium dewar, plus electronics; and the second for refrigerator and power supply. In the field test, the SG was suppo...
متن کاملStudies of Earth Dynamics with the Superconducting Gravimeter
I present investigations of Earth dynamics with the superconducting gravimeter GWR T020 at Metsähovi from 1994 to 2005. As a necessary background, the history and key technical details of the installation are given. Then a new data acquisition system (DAS) developed by the author is described. It has proved reliable and accurate. A pre-requisite for the study of weak phenomena is the removal of...
متن کاملEstimating the Mode Shapes of a Bridge Using Short Time Transmissibility Measurement from a Passing Vehicle
This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...
متن کاملf/sla from learner perspectives: a social activity or a cognitive process
in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...
