An ARMA (1,1) model comprises an autoregressive part and a moving average part and expresses each observation as a combination of the two: X t=ε t+X t−1 +ε t−1 where X t is the symptom severity score at time t, ε t is the error term.
The model comprises an electrically driven, tethered, single track vehicle and is based on the geometry and suspension characteristics of Challenger MBT.
The production perception model comprises an artificial computer-implemented vocal tract as a front-end module, which is capable of generating articulatory speech movements and acoustic speech signals.
The model comprises an accurate objective function of the structure production costs, subjected to design, resistance and deflection constraints in order to satisfy the requirements of the ultimate and serviceability limit states according to Eurocode specifications.
The model comprises an accurate objective function of the structure production costs, subjected to design, resistance, rotation and settlement constraints in order to satisfy the requirements of the ultimate and serviceability limit states according to Eurocode specifications.
Finally, the third model comprises an effort to generalize the previous van der Pol differential equations, both linear and nonlinear, where the ordinary time derivatives and integrals are replaced by corresponding fractional-order time derivatives and integrals of order p<2 (p="n−δ, n= 1,2,δ≪1).
The final model comprises a set of partial differential, integral and algebraic equations.
The shell model comprises a number of panels in the circumferential direction.
The Wiener model comprises a two-dimensional FIR filter followed by a nonlinear static mapping.
The model comprises a micro-cantilever with attached tip mass operating in the flextural flextural mode.
The model comprises a set of delay-differential equations; thus, the phase-space of the system has an infinite dimension.
