After SPC and before every training in our periodic retraining experimental protocol, we applied the same occurrence threshold, i.e., 1000 files, which corresponds to around 1 % of the training set size.
The mean velocity and turbulent stresses are compared with reference data of this experiment at the flow Reynolds number Re = 37,000 [Rapp Ch, Manhart M. Flow over periodic hills – an experimental study. Exp Fluids 2011 51].
The periodic variations of experimental and modeled TEC have been compared with solar and geomagnetic indices at ABOO and ASAB in 2014 and results indicate that the F10.7 and sunspot number as indices of solar activity seriously affects the TEC variations with periods of 16 32 days followed by the geomagnetic activity on shorter timescales (roughly periods of less than 16 days).
Such natural periodic dynamics of experimental data can provide important information in model fitting and error estimation.
In this experimental study, periodic line-like structures with different periodicities (5, 10, 19, and 300 μm) and structural depths (approximately 1 and 4 μm) were fabricated on stainless steel samples (AISI-304) by short-pulse laser interference and ultrashort-pulse laser patterning.
By performing then a time-based domain analysis, a periodic reconstruction of the experimental data is done and a periodically time-varying (PTV) electrical circuit model is extracted.
Atoms subject to a train of periodic HCPs provide an experimental realization of the kicked atom, a valuable test bed for the study of nonlinear dynamics in Hamiltonian systems.
Based on the periodic responses of the experimental data which included the flutter frequency and its third harmonics, the freeplay nonlinearity is approximated by a polynomial expansion up to the third order.
Most cell biologists like to work on defined proteins or periodic structures that allow experimental rigor by established criteria.
In the interpretation of experimental data, periodic behaviour may or may not exist when evaluating alterations in spectral power in response to intervention.
