Coal-bed methane (CBM), as an increasingly promising resource for the energy supply, deserves further exploration and accurate reservoir evaluation. It is also required to dynamically monitor the reservoirs (>200 m). Remote sensing methods in regular wavebands may fail in the depth sounding, with only imaging geo-objects shallower than 100 m. In contrast, the Super-Low Frequency (SLF) remote sensing...
Functional tests of field programmable analog arrays (FPAA) are required to assess tolerance to uncontrolled and unintentional variations in the components characteristic parameters, like for example a change in the values of capacitances and gains of the differential amplifiers which may be due to aging, uncertainty (i.e., a difference between the actual and nominal values), or to an outer disturbance...
In the field of the Side Channel Analysis (SCA), the electromagnetic radiation of a cryptographic device is the richest source of information. Indeed, it permits to be more accurate by positioning smartly the EM probe near a given logic, filtering the signal that is not useful regarding a given attack. But this advantage can become easily a drawback if the attacker is unable to position her probe...
