Autonomous navigation and parallel parking of robots is usually a challenging maneuver for conductors in industrial environments and in heavy traffic congestion respectively. Soft computing techniques are suited for robots like car control system when modeled by highly non linear differential equations and navigation in unknown and unstructured(More)
This work deals with the limiting distribution of the least squares estimators of the coefficients ar of an explosive periodic autoregressive of order 1 (PAR(1)) time series Xr = arXr−1+ur when the innovation {uk} is strongly mixing. More precisely {ar} is a periodic sequence of real numbers with period P > 0 and such that ∏P r=1 |ar| > 1. The time series(More)
