Today the independent component analysis (ICA) has been widely used in the blind source separation (BSS) to separate independent components in a data set based on its statistical properties. However, when the dimension of the input data is too high, the performance of the ICA may be not satisfactory. To address this problem, the present paper has proposed the new integrated method for the independent component extraction. The supervised manifold learning was firstly adopted to reduce the dimension of the input data, and then the kernel ICA (KICA) was employed to extract useful independent components in an efficient manner. The application of the proposed method has been successfully applied to the face image recognition. The experimental analysis has showed satisfactory and effective face image identification performance. © 2012 IEEE.

Combining with Jeffery equation and mechanics model of fixed point of Euler rigid body, research was done to study the mechanism and method of the short fiber radial orientation and characteristics of movement in tread extrusion process. The influence of tension flow field and shear flow field in flow channel on short fibers orientation has been systemically analyzed by flow characteristics of the tread during the extrusion process and combining with Jeffery equation and mechanics model of fixed point of Euler rigid body. The result show that the expansion ratio and the expanding angle of cross section are the key factors to determine the radial orientation of short fiber. Mathematical model of short fiber radial orientation was established. The extrusion die, which has a hinder dam by adopting such principle has been designed. The result also show that the best expansion ratio was 3-4, obtaining the average orientation angle between 70°-80°. and the rationality of the radial oriented mechanism and the mathematical model are verified. © (2012) Trans Tech Publications.

In this paper, we present a descent decomposition method for solving variational inequalities in equilibrium modeling, which can be viewed as an extension of the decomposition method proposed by Gabay and Mercier [4,5] by performing an additional projection step at each iteration. An optimal step length is employed to reach substantial progress. Under certain conditions, the global convergence of the descent method is proved. Preliminary numerical experiments are included to illustrate the efficiency of the new method. © 2011.

Biomass pyrolysis experiments were performed in a tubular reactor at different temperatures, the effects of which on organic structure of semi-char and tar had been investigated. Fourier-transform infrared (FTIR) analysis was conducted by a Nicolet 6700 FTIR spectrometer. The tar components at different temperatures were analyzed by GC/MS. It was observed that pyrolysis of biomass mainly occurs in the temperature range of 300-600 °C. A high temperature favored the production of gases. The yield of semi-char and the contained organic functional groups(C. O, C. C, C-H, C-O and OH) decreases significantly with the increasing final temperature. The tar yield passes through a maximum at about 500 °C. The organic functional groups in tar were stable but the transmittance of these groups decreased with the increasing final temperature. © 2012 Elsevier Ltd.

An adaptive image interpolation approach is proposed in this paper. The proposed approach imposes a regularization on the reconstructed high-resolution image to suppress the noise and blurring incurred in the observed low-resolution image. Furthermore, the proposed regularization scheme is steered by the local gradient information of the image, which is evaluated using a probabilistic measure. Experiments are conducted to demonstrate the superior performance of the proposed approach. © 2011 Elsevier B.V. All rights reserved.

So far, feather and down category recognition is often done by man with a microscope, but this method has some disadvantages. So a feather and down category recognition system is proposed in the paper [1], and then feather and down category recognition can be done by computer automatically. After the image processing and segmentation using GA, the triangle node of two-value image of feather and down is to be recognized with SVM, then the triangle nodes which have been recognized will be matched and the distance between the matched triangle nodes is calculated, in the end, the feather and down category is recognized. After lots of experiments, it is found that the recognition rate is lower than artificial recognition. In order to improving recognition rate, RBF kernel SVM and MOAA SVM are introduced into the recognition system, and a revised feather and down recognition model is put forward. It is shown that it is efficient to feather and down recognition. © 2010 IEEE.

Cyclic codes are an interesting type of linear codes and have wide applications in communication and storage systems due to their efficient encoding and decoding algorithms. In this paper, let Fr be a finite field with r = qm. Suppose that g1, g2 ε F* r are not conjugates over Fq, ord(g1) = n1, ord(g2) = n2, d = gcd(n1, n2), and n = n1n2/d. Let Fq (g1) = Fqm1 , Fq(g2) = F q m2, and Ti denote the trace function from Fqmi to F q for i = 1, 2. We define a cyclic code C(q,m,n1,n2) = {c(a, b) : a ε Fq m1 , b ε dbl;Fq m2 }, where c(a, b) = (T1(ag0 1) + T2(bg0 2 ), T1(ag1 1) + T2(bg1 2), ⋯ , T 1(agn-1 1 ) + T2(bg n-1 2 )). We mainly use Gauss periods to present the weight distribution of the cyclic code C(q,m,n1,n2). As applications, we determine the weight distribution of cyclic code C(q,m,qm1-1,qm2-1) with gcd(m1, m2) = 1; in particular, it is a three-weight cyclic code if gcd(q -1, m1-m2) = 1. We also explicitly determine the weight distributions of some classes of cyclic codes including several classes of four-weight cyclic codes. © 2014 IEEE.

In this study, the Fe3O4 magnetic nanoparticles (MNPs) were synthesized as heterogeneous catalysts to effectively degrade methyl orange. The coulping method of microwave irradiation and Fenton-like reaction was used for degradation of methyl orange waste water. The effects of Fe3O4 dosage, initial H2O2 concentration, catalyst cycles, reaction temperature and so on were assessed systematically. The experimental results showed that the microwave-assisted Fenton-like process using H2O2/Fe3O4 was the most effective treatment process compared with other traditional methods. According to degradation of methyl orange, it has been found that the oxidation by Fenton-like's reagent is dependent on Fe3O4 dosage, H2O2 dosage, reaction temperature. The results indicate that under the optimal conditions, the removal rate of methyl orange could reach nearly 100%. Moreover, six cyclic tests for methyl orange degradation showed that the magnetic catalyst was very stable, recoverable, highly active, and easy to separate using an external magnet. Hence, the coulping method of microwave irradiation and Fenton-like reaction with magnetic nanomaterials of Fe3O4 as the catalyst has potential use in organic pollutant removal. © (2014) Trans Tech Publications, Switzerland.

The 3D temperature distribution in high-power double-clad fiber laser (DCFL) and the evolution of the temperature field in the fiber are analyzed, according to the transient heat conduction equation. The temperature in the fiber reaches the maximum after opening the pump light about 20 s, and cools down to the room temperature after shutting down for also about 20 s. The shape of the inner-clad can only affect the spacial distribution of the temperature outside of the core, but have no effect on the maximum temperature in the core. © 2010 Elsevier GmbH.
