Background and Objective The objective of the program was to determine if Distributed Acoustic Sensing (DAS) systems, for this program specifically a system supplied by hifi Engineering, could reliably detect leaks given the conditions present in these tests. ...
Miniaturized photoacoustic gas sensor based on patented interferometric readout and novel photonic integration technologies. A new European consortium, MINIGAS, led by VTT Technical Research Centre of Finland, is developing a miniature gas sensor to detect greenhouse ...
In the mid-1990’s, Atmospheric Systems Corporation (ASC) independently developed an acoustic remote sensing unit called a Doppler miniSoDAR (or miniSoDAR for short) for high-resolution wind profiling in the lowest 200 meters of the atmosphere. ...
Recently, many different schemes have been employed to calculate the SBL height, but there are many problems with applying these models in environmental studies. Remote sensing of the atmospheric boundary layer using an acoustic sounder provides an opportunity to assess the mixing height based on analysis of SODAR echo strength. ...
Significant advances in modern technology, especially in the past 30 years, have opened up the depths of the ocean to observations that were impossible previously. Techniques such as remote sensing, acoustic monitoring, remotely operated underwater vessels (ROVs) and robotic free-flowing floats are being used to measure ocean temperature, salinity, the strength ...
He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose consciousness and possibly his life. ...
It is shown that acoustic spectroscopy can sense the presence of a small sub-population of large particles in a concentrated dispersion of much smaller particles. ...
