Both are a bit more elaborate than the sparse "Time" interface on the new Pebble Time Steel, which places important information on a timeline that stretches both forward and backward in time.
Randomly taking 1% of the time-frequency coefficients results in a very sparse time-frequency representation that sounds like clicks, breaks, and musical noise when re-synthesized. 2.
The sparse time varying multipath channel is modeled as h ( t, τ ) = ∑ l = 0 k − 1 α l ( t ) δ ( τ − τ l ( t ) ) (84).
This paper proposes a pattern recognition based differential spectral energy protection scheme for ac microgrids using a Fourier kernel based fast sparse time-frequency representation (SST or simply the sparse S-Transform).
In case of voiced speech, it should be a perfect semi-periodic impulse train which is zero most of the times, i.e., it is a sparse time series.
By rearranging the column vector x into a matrix with the size of K×K, we obtain the sparse time-frequency distribution matrix of the filtered out Bragg peak s.
However, models have mostly employed a daily time-step and have used a rather simple net calculation of the net photosynthesis, particularly for the estimation of future rice yield because the temperature projected by climate model still has sparse time scale.
For voiced sounds in particular, the filter is assumed to be an all-pole linear filter and the source is considered to be a semi-periodic impulse train which is zero most of the times, i.e., the source is a sparse time series.
This sparse time-lapse strategy should be useful for any assay where cell responses play out over a few days.
In fact, for HIV it has been shown previously that many factors (such as long period of infectivity, sparse time and space sampling) can limit the concordance of phylogenetic reconstruction and the reported epidemiological evidence [41], [42], [43].
