In this paper,a controller is designed for a group of cooperative robots to achieve the stable displacements.Communication network among the robots is assumed unavailable and each robot can only measure the displaceme...
Measurements of neutron count rate (0.025 eV to 10 MeV) at ground level were performed with a single free (He-3) tube detectorthat is located near ground level in Aeronautical Institute of Technology (ITA) Silo ...
Housing, education and green energy were among six areas of consumption identified by anOctober 29 State Council meeting chaired by Premier Li Keqiang as targets for stimulus. The meeting also called for improving eco...
