Such a virtual experiment will be driven by the excitation function i([theta], [r.sub.p]) obtained from the design Eq.
where [beta](x;[theta]) is an SP expressing the spatial randomness in the excitation function. Also, [beta](x;[theta]) can be expanded using (3) with [[gamma].sub.j] and [g.sub.j](x) as the eigen values and the eigen functions, associated with its covariance kernel, respectively.
They also found that after the onset of hearing an elegant refinement of the neuron's excitation function takes place.

where X(i[omega]) is the response function and F(i[omega]) is the excitation function. The viscous damping or dashpot has frequency dependence.
The correct characteristics of the neural network sorter possibly are because the generalization ability and excitation function of neural network have some saturation areas.
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.
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

AAM and OAM equatorial excitation functions (in complex notation) [chi] = [[chi].sub.1] + i[[chi].sub.2] are given in rotating terrestrial frame, so they must be first transformed into celestial (non-rotating) one.
