Cobalt oxide (Co3O4) was homogeneously coated on multiwalled carbon nanotube through a simple chemical deposition method and employed in supercapacitor electrodes. SEM image indicated the uniform distribution of Co3O4 nanoparticles on the surface of the multiwalled carbon nanotube. A maximum specific capacitance of 273 Fg(-1) was obtained at the(More)
—A 16-core processor with both message-passing and shared-memory inter-core communication mechanisms is implemented in 65 nm CMOS. Message-passing communication is enabled in a 36 Mesh packet-switched network-on-chip, and shared-memory communication is supported using the shared memory within each cluster. The processor occupies 9.1 and operates fully(More)
An energy-efficient programmable LDPC decoder is proposed for WiMax and Wi-Fi applications. The proposed decoder is designed with overlapped processing units, flexible message passing network and medium-grain partitioned memories to achieve flexibility, area reduction, and energy efficiency. The decoder can be programmed by host processor with several(More)
An advanced hierarchical parallel evolutionary algorithm (AHPEA) is proposed in this paper. To solve the problems caused by " homogeneous subpopulations " and " synchronous migration " of the traditional algorithm, AHPEA builds a heterogeneous model and adequately connect subpopulations. Once a subpopulation satisfies the migration conditions, it is allowed(More)
Based on the analysis of operation safety data of expressway and the investigation on the spot, the influence of the horizontal, vertical, cross-sectional alignment index on safety were studied. The vehicles track was seemed as the three-dimensional curve. According to the road alignment space geometric properties, the compound curvature of the horizontal(More)
In view of the data sparseness problem existed in the traditional collaborative filtering recommendation algorithm, this paper proposes a hybrid collaborative filtering recommender framework integrated FCM clustering and Slope One algorithm and FSUBCF algorithm. Firstly this algorithm use the Slope One algorithm based on FCM cluster to predict item ratings(More)
