Solution to the safe and collision-free trajectory of the wheeled mobile robot in cluttered environments containing the static and/or dynamic obstacle has become a very popular and challenging research topic in the last decade. Notwithstanding of the amount of publications dealing with the different aspects of this field, the ongoing efforts to address the more effective and creative methods is...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...

The paper considers the dynamic stability of submerged pipelines with denudation and sagging depending on their stiffness river flow rate. hydrodynamic force frequency natural vibrations pipeline are calculated at actual critical length sagging. It is shown that external applied to sagged corresponding critical, coincides vibrations. found loss occurs in resonant region vibration due increased ...
