The correct characteristics of the neural network sorter possibly are because the generalization ability and excitation function of neural network have some saturation areas.
2006, Revised atmospheric excitation function series related to Earth variable rotation under consideration of surface topography.
They also found that after the onset of hearing an elegant refinement of the neuron's excitation function takes place.
This allowed the researchers to separately record the inhibition and excitation functions of the neurons.
Generally, for this type of optimization, a detailed model of the system would be developed that would represent the thermodynamic and physical relationships between the components of the system, and the dynamic response of the system to one or more standardized excitation functions would be simulated using a short time step [Jreijiry (2003), Park (2008), Riederir (2005), Treado (2011)].
system of Boolean equations of excitation functions of elementary memory automatons:
The spectra of geophysical excitation functions, multiplied by Brzezinski transfer function, are shown in Figures 6, 7 and 8 for above mentioned NCEP, ERA-interim and ERA40 solutions, respectively.
Excitation functions display much higher power in motion/wind term than in matter/pressure one, but their influence on nutation is much smaller, due to a smaller multiplicative coefficient aw in Eq.
Namely we use the integration of the series of the atmospheric (NCEP/NCAR, ERA40) and oceanic (ECCO, OMCT) excitation functions and search for the coherence between the integration and the celestial pole offsets obtained from VLBI observations
First pair is the pressure and wind terms of atmospheric angular momentum excitation functions (AAMF) from NCEP/NCAR re-analysis, in the interval 1983.
