In this paper, we employ distributed jointed source-channel (DJSC) coding based on quasi-cyclic low-density parity-check (QC-LDPC) codes in our wireless sensor network (WSN) for seismic exploration. In order to reduce the latency of jointed decoding, we propose a parallel structure of jointed decoding, and decoders of multiple sources can decode simultaneously. We make use of the soft information...
Considering the fact that the wireless sensor networks (WSNs) need to maintain a long lifetime, there is a great demand to decrease energy dissipation of the sensor. Data compression is an efficient method to solve the problem. This paper proposes a practical and efficient data compression algorithm with high compression and noise-resisted features, in which the quasi-cyclic low-density parity-check...
Numerical model of Element Free Galerkin Method (EFGM) coupling Finite Element Method (FEM) for retaining wall is proposed. Concrete was calculated by EFGM and reinforcement was simulated by truss elements in FEM. The stiffness matrix of the whole structure was gained based on displacement compatibility condition. Via analyzing one RC retaining wall, the calculation shows that the method is feasible.
Water hydraulic technology has been developing rapidly over the past decades due to its outstanding advantages, including cleanliness, security, environmental protection and cost-effectiveness and so on. At present, the research and development of water hydraulic servo valve with the performance of high precision, frequency response and high reliability become an important direction of water hydraulic...
