This second stage was implemented using Markov chain Monte Carlo (MCMC) methods through the software WinBUGS (Spiegelhalter, Thomas, & Best, 2004).
As both pitch detection algorithms deliver frame-based f 0 sequences, an intermediate processing stage was implemented where f 0 sequences are converted into tones.
9 To boost the disappointing sample size resulting from this automatic stage, a second and significantly more labour-intensive (manual) stage was implemented.
Since the conditioning variable should not have any items with significant DIF, a prior purification stage was implemented before the definitive item DIF analysis.
For very large cities (e.g. Mexico City and Beijing), a fourth sampling stage was implemented based on the random selection of city geographical sub-divisions, with probability proportional to city sub-division population.
To investigate the formation of magnetite and feroxyhyte at short contact times without modifying the geometrical characteristics of the reactor (and therefore the fluid dynamics), an interface with several outlet stages was implemented.
Finally, a tracking stage is implemented using Kalman filtering techniques.
Further, the synchronization stage is implemented at sampling time which yields extremely high complexity.
The proposed method, along with other needed preprocessing stages, is implemented on Field Programmable Gate Array chips.
We have presented a perceptual image wavelet encoder whose 2D-DWT stage is implemented using CUDA running on a GPU.
