This paper presents the chaotic issue of flexible arms on the wheeled humanoid robot. A chaotic attractor may be induced from the unpredictable turbulence and unstable periodic orbits (UPO) embedded in the internal dynamics. Based on differential geometry, the proposed nonholonomic system can be decomposed into subsystems using the normal-form methodology. However, the high-order nonlinearities of...
As magnetic recording densities grow, the nonlinear distortions, known as transition shift and partial erasure, arise and limit the performance of the detector. Despite that the transition shift can be compensated by a write current technique, the effect of partial erasure complicates the evaluation of the correlation functions for the storage data and the nonreturn-to-zero-inverted modulated data...
Nonlinear effects arise in the high-density magnetic recording, which causes a performance degradation of the corresponding detector. Design of the timing recovery is crucial for the detector, and it becomes complicated in the presence of the nonlinear effects. In this article, we examine the effects of the Muller & Mueller's phase detector for a nonlinear magnetic recording channel. For simplicity,...
