In this paper, we discuss the properties of the eigenvalues related to the symmetric positive definite matrices. Several new results are established to express the structures and bounds of the eigenvalues. Using these results, a family of iterative algorithms are presented for the matrix equation AX=F and the coupled Sylvester matrix equations. The analysis shows that the iterative solutions given by the least squares based iterative algorithms converge to their true values for any initial conditions. The effectiveness of the proposed iterative algorithm is illustrated by a numerical example. © 2013 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.

Ceramic ultrafiltration membrane was applied to treat the desulfurization wastewater to avoid environmental pollution and further reclaim sulfur. However, membrane fouling is unavoidable. The key issue to solve the fouling problem is to understand the fouling mechanism, and find an effective way to regenerate the membrane. The results showed that the dominant resistance was caused by cake formation even at a low sulfur concentration. The filtration mechanism was tested to fit the complete pore blocking model. Sulfur and tar oil deposition on the membrane surface was significant, along with salts such as thiocyanate in the wastewater. Based on these, the effectiveness of various membrane cleaning methods was evaluated. The most effective one was adding 1% (w/w) NaOH solution mixed with 0.5% (w/w) NaClO, and then cleaning for 120. min at 50. °C, eventually the flux recovery ratio was always higher than 98%. Such effectiveness has verified the compositions of the foulants vice versa. Therefore, the ceramic UF membrane can be reused as a good alternative in the wastewater treatment. Foundation of ceramic UF membrane in the treatment of desulfurization wastewater. Fouling causes were sulfur and tar oil deposition on the membrane surface. Fouling mechanism was completion of pore blocking, and then cake layer formation. Propose an effective cleaning method with a flux recovery ratio higher than 98%. © 2013 Elsevier B.V.

Image fusion is a process of integrating different information of multi sensors into one representation. In this paper, a novel image fusion method is proposed based on an improved dual-channel pulse coupled neural network (PCNN) coupled with black-based random image sampling and non subsampled Laplacian transform (NSLP). The NSLP is used to decompose the source images to provide sparse high frequency subbands coefficients, and the block-based random image sampling is introduced in to measure the image features. The improved dual-channel PCNN is modeled based on the original dual-channel PCNN, in which the linking parameters are set to adaptive according to image features, the multiply operation is substituted by maximum and the level factor is abandoned. The fused image is obtained by normalizing the last internal state of the improved dual-channel PCNN. Meanwhile, some measures are taken to reduce the computational complexity of the proposed fusion method without reducing the fusion quality. Three groups of images, including CT and MRI medical images, infrared and visual images and visual and millimeter-wave images, are used to test the validity, and the experimental results demonstrate that the proposed method not only can obtain the fused image with high fusion quality in terms of better visual effect and better objective evaluation criteria, but also guarantee the low computational complexity. © 2016, Revista Tecnica de la Facultad de Ingeniera.

Children as a kind of weak consumers, the status of their food security are the focus of society and media. In order to study the condition of the barrier-free packing of children's food, combining with children's psychological and physiological characteristics and on the basis of relevant laws and regulations of food and food packing safety, this study uses the screening index of Principal Component Analysis (PCA) to build a set ofaccessible pre-warning index system for barrier-free packing of children's food and then uses the trapezoidal fuzzy Analytic Hierarchy Process (AHP) to weigh the two-leveled index in the system and establishes the pre-warning model for children's food packing by means of the fuzzy comprehensive evaluation, finally analyzes the relative importance of each index for influencing children's food barrier-free packing based on certain cases and provides some corresponding suggestions to improve the level of barrier-free packaging for children's food. © Maxwell Scientific Organization, 2015.

Preschool children belong to a special group. In order to study method of food packing design of them, this study firstly investigates children's food market, some parents and teachers of kindergartens, as well as some food security regulators of the relevant food security management departments. Then the article comes up with 5 design factors: the packing opening way, intelligence functions, graphics, color and text, which have greater impact on preschool children's food security. Based on these 5 factors; combined with the physiological and psychological characteristics of preschool children, it systematically analyzes the design method of the food packing security. © Maxwell Scientific Organization, 2015.

In this paper, an iterative algorithm is established for solving a class of matrix equations with complex unknowns. By using the hierarchical identification principle, the gradient-based iterative algorithms are constructed to solve the equation AXB + CXHD = F and the coupled equations A1XB1 + A2XHB2 = F1 and C1XD1 + C2XHD2 = F2. The the convergence factor is presented to guarantee that the iterative algorithms are effective for any initial values. The analysis indicates that if the matrix equation has a unique solution, then the iterative solutions converge to the exact one for any initial value under proper conditions. A numerical example is provided to illustrate the effectiveness of the proposed algorithm. © 2014 IEEE.
