According to this model, reviewed in [2], the segmental pattern is established in the PSM by a mechanism involving an oscillator (the segmentation clock), which is hypothesized to set the periodicity of the process, and a travelling wavefront of cell change that sweeps anteriorly to posteriorly through the PSM, arresting the oscillation, and inducing (or permitting) somite maturation.
The user selects the cluster (industrial zone or city center) and the nodes from where the sensing campaign will take place, the sensing time for each node, and the periodicity of the sensing process and triggers the communication between the geolocation database web server and the LOG-a-TEC sensor network.
Finally, we apply a parsimonious double-cyclostationary stochastic model to generate hourly synthetic time series preserving the marginal statistical characteristics, the double periodicity and the dependence structure of the process.
In the first part of the paper, simple models demonstrate that the periodicity of such processes can be optimized in three settings: fixed desorption time, variable desorption time, and variable species concentration in the gas space.
Period of nighttime Pc3 waves is to be determined either by the periodicity of energy release process, or by band-pass filtering which can occur during the wave trapping and propagation along the magnetotail waveguide (Mazur et al. 2010).
In this context, we analyze observations from Athens, Greece and we investigate the marginal distribution of the solar radiation process at a daily and hourly step, the long-term behavior based on the annual scale of the process, as well as the double periodicity (diurnal-seasonal) of the process.
Figure 1 presents an overview of the process by which estimates of the periodicity of symbolic data were obtained in this study.
Gallagher exposed the resampling process by investigating the periodicity of the second differentiation of interpolated signals [2].
These observations identify the effects of noise with a representation of vibration frequency in SI, and are consistent with suggestions that the representation of frequency is improved by adaptation of neurons in SI, and that this adaptation process is driven by periodicity of the vibrotactile stimulus.
Extensive genetic and other studies have identified a wide range of genes involved in this process including genes which alter the periodicity of the cycle (dec genes) [ 4, 5].
Because Dictyostelium cells exhibit oscillatory shape dynamics, we model contact guidance as a process in which stochastic cellular harmonic oscillators couple to the periodicity of the nanoridges.
