NHK has proposed a famous 3D audio system: 22.2 multi-channel system, but its loudspeakers are too many and are troublesome to put in home. Ando and Wang has proposed two simplification methods to reduce its channel number, but only 3D sound field at the central listening point can be recovered well by NHK 22.2 system and its simplified systems, the listening experience at a non central listening...
This paper proposes a general multichannel system reproduction method. Firstly, relative to original multichannel system, a general global model is build up by guaranteeing sound pressure and the direction of particle velocity at the receiving point constant, and making the square error of particle velocity magnitude at the receiving point as little as possible. Then the model is equivalent to a least...
In this paper, two quaternion-based nonlinear filtering methods are applied on the processing of measurements from the low-cost Micro-electromechanical Systems (MEMS) based Inertial Navigation system (INS) and Global Positioning System (GPS). One approach employs an Extended Kalman filter (EKF) propagating the quaternion vector using conventional vector addition operation. However, due to the fact...
This paper proposes the methods of generation of the energy-efficient trajectory and the centroid trajectory for the biped robot. Based on the function approximation method, the energy-efficient trajectory between the initial state and the terminal state is generated by converting minimization of energy consuming to minimization of input torques. Reducing the biped robot to an inverted pendulum, the...
