This led to a general action to wipe out all possible traces that could be considered as compromising.
The contingent leaves traces that could be visible to the American military using high-resolution cameras in unmanned planes and technology sensitive to body heat, said a former American law enforcement official, now in Pakistan.
But because the test was conducted underground, thus concealing many of the tell-tale traces that could be used to get a clearer picture of the bomb design, it may not be possible to conclusively determine what kind of device was used.
For instance, the Royal Canadian Mounted Police are developing a technology to "fingerprint" diamonds, identifying them by trace impurities that could be traced to known mines.
It is demonstrated that very high degrees of closure for a CES enable experimental observation of small imbalances in atmospheric cycles or slow accumulation of trace gases that could otherwise be masked by dilution with atmosphere external to the CES.
The first flaw with this is that the memory will most likely still have trace fragments that could be pulled.

We present here ChirCor v1.0, a program for managing physical-log data (P-wave velocity and density) and chirp-sonar seismograms, also equipped with a synthetic-trace generator, that could be used for correlating real seismograms to synthetics.
In abandoning the program, called the National Animal Identification System, officials said they would start over in trying to devise a livestock tracing program that could win widespread support from the industry.
