We focus on {0, 1}-matrices of size 8×8 and provide a unified method to construct all {0, 1}-matrices of size 8×8 whose branch numbers are 5. And using the constructed results, we can find that the total Hamming weight of them varies from 33 to 44. While the type of total Hamming weight 44 has been used in cipher E2 and Camellia, we can use the other types in designing linear transformation of an...
This paper introduced fuzzy assessment of water quality based on membership grade by artificial neural network. Samples were obtained by intensive interpolation of water quality standards, relative MG matrix was output as expectation value for network's train and application. Then, improved fuzzy mathematics method was applied to assess the water quality of Qingdao Dagu River.
The blind multi-channels identification problem is studied in this paper. A cost function based on the orthogonal property between the output autocorrelation matrix and the channels parameter matrix is first constructed for a signal-input multiple-output FIR system. Then, an improved particle swarm optimizer, in which the personal best particle is replaced with the weight average of personal best...
This paper presents a new approach for linear system identification with additive noisy output. It treats the model of system identification as an independent component analysis (ICA) problem with source signals received by several observed signals so that the estimation of noise can be obtained from the observed signals. By using some special characters of the mixing matrix, the ambiguity inherent...
This paper presents a novel algorithm for multiple subtraction based on independent component analysis (ICA) which takes into account the scale inconsistencies between the predicted and the true multiples. The proposed method avoids the unrealistic assumption in recent ICA based method that all the scale coefficients should be the same. Moreover, it settles the two ambiguities of the separated primary...
