The analysis FB converts the time domain signal to the frequency domain (similar to the well known DFT operation) and the synthesis FB converts the frequency domain presentation back to time domain (similar to the IDFT operation).
It is well known that the operation of distance relays relies on the power frequency components to calculate the fault impedance and hence make decision on tripping.
Although the efficiency of this technology in terms of sludge dewatering and mineralisation is well known, design and operation parameters are yet to be standardised.
The US ran a military and intelligence base on a now disused-airfield in the area for much of the Iraq war and the terrain of the rugged 45 mile ridgeline is well known to special operations units.
The (Hitchcock-) transportation problem is a well known problem in operations research [6, 9, 10] and can be solved in polynomial time by fast algorithms (see e.g. [12]).
This optimization problem is well known to the operations research community as the discrete p-median or the facility location problem (Berman and Krass 2002).
The threat from buried bombs was well known before of the operation.
The method of testing is based on a very well known principle of the operation of an inclined plane.
