    For solving the redundancy of nodes and edges in concept lattice, we replace lattice with join-semilattice and present an algorithm which relies upon a strategy of gradual insertion of the concepts into the partially built hasse diagram. A threshold value is introduced to limit the number of concept nodes. We present the implementation of this algorithm and demonstrate the process of concept semilattice updating by an example. Experimental results show its effectiveness and efficiency. View full abstract»

    Adaptive critic designs is a method used to approximate optimal control over time in nonlinear systems, which is suitable for dealing with time-varying complex systems and dynamic varying complex tasks. On the other hand, the boiler combustion system is a typical plant with multiple inputs/multiple outputs, non-linearity and time-delay, and the coupling relationship between its parameters correlated with combustion process is very anfractuous, so it is very hard to control the combustion process with conventional control methods. This paper uses action-dependent adaptive critic designs to consider the solution of boiler combustion multivariable control systems, realize the emulational control of boiler combustion process, make the main steam pressure around rated value and the furnace negative pressure and the oxygen content in the exhaust gas varied within a certain range, and finally analyze the learning capacity, controlling effect and adaptive capability of the approach.

    To find an easy experimental way for evolvable hardware (EHW), an closed loop platform was discussed based on a field programmable gate array (FPGA) chip, a microprocessing unit (MPU) and the software tool-Quartus II. A binary digit to VHDL converter was proposed. It facilitated the using of the different FPGA chips as evolving carriers and avoided learning of the technological details inside the chips and analyzing of the different and complicated bitstream structures of chips. Tool command language (Tcl) scripting was used to create a Quartus II projectand add VHDL files into the project automatically. Command-line operation and batch processing were used to achieve analysis, synthesis, and programming FPGAs automatically step by step. The closed loop was implemented, which is the key of online evolution study for EHW. The students can conduct EHW experiments and needn't to know the bitstreamstructures of FPGA with the closed loop platform. View full abstract»

    Chaos-based PN sequence generators are widely investigated recently. Concrete implementation of theses chaos-based generators usually have some problems because any processor or chips are computation precision restricted, which greatly effects the statistical properties of a chaotic PN sequence. This paper proposes a couple chaotic systems based stochastic bit quantification algorithm, which extends the period of the chaotic PN sequence and strengthens the anti neural network based adaptive parameter attack ability under precision restricted condition. The balance and correlation properties of the generated sequence are analyzed. The sequence is proved to be a binary Bernoulli sequence and the side lobes of odd/even auto and cross correlation are proved to obey normal distribution N(0, 1/N). Experimental results show that the algorithm has excellent statistical properties, and can be used to generate PN sequence with higher quality than conventional schemes. View full abstract»

    In order to guarantee the reliable real-time video transmission of overlay multicast network (OMN), a layered multicast tree with three-level is proposed based on NICE protocol to manage multicast service nodes. This solution can improve the data-transmitting efficiency, and minimize the redundant packets in OMN. Also, for the reliable video transmission in bandwidth-limited links of OMN, a QoS algorithm is analyzed by discarding the redundant frames of the video sequences according to the detected network condition. Finally, the performance test verifies the validity of proposed layered multicast tree for reliable video transmission. View full abstract»

    Adaptive infinite-impulse-response (IIR) filter provides a powerful approach for solving a variety of practical problems. However, they might have a multi-modal error surface and their design is formulated as a highly nonlinear optimization problem. By integrating chaos mechanism and niche technique, a novel immune optimization algorithm based on the clonal selection principle and idiotypic immune network theory exhibited in biological immune system with global optimization ability, called multi-modal immune optimization algorithm(MIOA), is proposed for digital IIR filter design in this paper. Taking advantages of the ergodic and stochastic properties of chaotic variable, an adaptive chaos mutation operator is designed by the combination of prior knowledge of antibody and evolution iterations, the new algorithm has the advantage of preventing from prematurity and fast convergence speed. Simulation results show that the proposed approach is accurate and has a fast convergence rate, and the results obtained demonstrate that the proposed method can be efficiently used for digital IIR filter design.

    It's difficult to filter an image while protecting its detail. In this paper, a novel filter is proposed for detail preserving restoration of images. Corrupted pixels are detected by a multi-scale way. For the corrupted pixels, we use a kind of four direction interleaved interpolation value to replace their value. The performance of the proposed operator is tested for different test images corrupted at various noise densities. Experimental results show that the proposed filter can not only provide better performance of suppressing noise but also preserve more detail features. It is also demonstrated preferable performance in suppressing different impulse noise density from 10% to 90%. View full abstract»

    An image fusion algorithm is presented based on fuzzy logic and wavelet in this paper. Aiming at the visible and infrared image fusion, we analyze the pixel-level image fusion algorithms, and addresses an algorithm based on the discrete wavelet transform and fuzzy logic. We created two fuzzy relations, and estimated the importance of every wavelet coefficient with fuzzy reasoning. According to the importance of coefficients, the weighting average coefficients were calculated. Ultimately, we reconstructed the fused image through inverse wavelet transform. In the experimental section, we verified the effectiveness of the algorithm with two actual image data acquired from the field experiments. View full abstract»
