Aiming at the gain planning of SCUT-I humanoid robot, a stair motion pattern, controlled by step lengths, step period and other walking parameters, is designed. And stair restrict condition is described. According to the parameters and restrict equations, hip and ankle trajectories are planned based on IPM (inverted pendulum model). Finally, according to the model parameters of SCUT-I robot, the robot...
The paper conducted the research on surface heat transfer coefficient of external cross-flow over tube bundles, proposed two different measures on calculating surface heat transfer coefficient of the tube bank according to law of conservation of energy, gained two groups of results through calculation examples, and analyzed discipline of the change of convection bank surface heat transfer coefficient.
The connection bridge is addressed for connecting different circuit part include two CPU system in a SoC. With the discussion about the performance of circuitry components, the circuitry components are classified into two types, one is called host transmission component, and the other is called slave transmission component. The classification is the fundamental for connection bridge design. By this...
Ad hoc network has dynamic topology and large-scale nodes, for the purpose of monitoring and measurement in Ad hoc network, this paper proposes a new frame method of hierarchy model for monitoring, i.e., clusterhead selection mechanism. The mechanism designed a weight formula to handle the comprehensive update considering several factors such as distance, mobile rate, energy during the model establishment...
On the basis of phase relationships in the Ca–Si–Al–O–N system, a Ca–α–sialon ceramic was synthesized using the hot-pressing technique. The reaction sequences and densifications of the Ca–α–sialon vs. firing temperatures have been characterized in detail. The present experiments reveal a reaction sequence as follows: at 1250°C the reactant mixture started to soften, at 1300°C a gehlenite phase was...
