After we reconstructed a sample of the structure of the social graph of Facebook, we unveiled its community structure.
Most of the naturally occurring signals are sparse in some domain, and thus, CS techniques are able to reconstruct a signal sampled at sub-Nyquist rates.
The refinement layer packets in resolution carry the refinement information which can be used together with the base layer packets to reconstruct a full VGA sample of the video, as shown in Figure 14. Figure 14 The H. 264 scalable encoded video composes of two embedded resolutions.
OPT uses projection images of the sample to reconstruct a 3D model of the sample (demonstrated in Additional file 1), a process that overcomes many of the shortcomings of the other methods listed above.
Many tasks in the context of data acquisition with a wireless sensor network, e.g. angular resampling or jitter compensation, can be solved by reconstructing a uniformly sampled signal from a nonuniformly sampled one.
Moreover, it is proved that the expected total cost (number of measurements and reconstruction combined) needed to sample and reconstruct a k-sparse vector in R n is no more than k logn + 2k.
The proposed interpolation methods can correct ADC linearity errors and increase the dynamic resolution of an ADC or they can reconstruct a signal from fewer samples in non-uniform distance.
For the two ancestral nodes reconstructed, a weighted sampling of 10,000 sequences from the posterior distribution resulted in ancestral sequences that were either identical (parrot/passerine ancestor, 100% identical), or highly similar to (passerine ancestor, 83% or 8343 sequences out of 10,000 identical) the most likely ancestral reconstruction.
This is motivated by the Nyquist-Shannon sampling theorem, which states that in order to accurately reconstruct a signal it must be sampled at a frequency at least twice the highest frequency present.
For our dataset, the average time required to sample and reconstruct a -second epoch is seconds on an Intel Core2 Duo 2.50 GHz system with RAM.
