Figure 1: DWT of u n to level J = 4: the sequence u n is decomposed into an approximation a 4 and details d 1 , d 2 , d 3 et d 4
Figure 2: Synoptic diagram of the wavelet denoising method.
Figure 3: signals I and Q and Doppler spectrum of the cell N 1 It is noticed that the estimate of the mean velocity of the wind by the pulse-pair algorithm is close to the real speed

Thermophilic species of turritellids have continued to the Recent and large, thick-shelled species still inhabit modern tropical platform environments. To observe such specimens in

Of course the peak corresponding to the 140 Ω discontinuity remains unchanged, while the peaks corresponding to the discontinuities behind the fault (from the source position)

As an alternative to the deterministic framework, we propose to handle the problem in the Bayesian framework which will provide a tight minimal bound over all the range of

We have discussed the generation of ultrashort pulse trains with very high repetition rates in the anomalous dispersion regime of a fibre, the generation of parabolic shaped pulses

This control technique of systematic gate bias pulses demonstrated a 10 dB improvement of amplitude P2P stabilities for this worst-case radar burst to meet the critical

The figure 10 shows an example of heart rate estimation using SSA scaled eigen value method and AM-FM demodulation, where we can see that the AM-FM estimation

The method is based on the use of an optically-carried radiofrequency (RF) signal in order to benefit from both the directivity of the optical beam (Lidar), and the accuracy of
