... solving linear partial differential- algebraic equations (PDAEs) of the form: Au t + B∆u = f(x, t) (1) where A is a singular, symmetric and nonnegative matrix, while B is a symmetric positive ... −1)(n−r) . Then, the initial condition (6), with E ≡ I becomes V (0) = V 0 . (26) Moreover, the initial condition (6) must satisfy a hidden constraint W 0 = ˜ F 2 (0). For solving th...

... When the input signal properties vary with time, the adaptive filters are able to track these variations. The aim of tracking performance analysis is to characterize this tracking ability in nonstationary environments. ... variations in the optimal weight vector. The steady-state performance of this algorithm in the nonstationary environment for the white input is presented...
