A concise formula depicting the relation between strain energy release rates and generalized stress intensity factors for two-dimensional V-notches is presented. The distributions of stress components before the notch in an arbitrary direction are written in the same form as that of the bisector direction by introducing arbitrarily directional generalized stress intensity factors. The asymptotic displacement components due to notch propagation are obtained by means of the stress intensity factor of the crack emanating from the root of the V-notch, which is directly evaluated via generalized stress intensity factors of a perfect notch in the absence of the crack itself. Then, the stain energy release rate is derived through calculating the work that would be done by the forces applied to closing the notch again. Finally, effects arising from the geometric parameters of V-notches are discussed.

In generalized fuzzy operator method, display effect is realized by adjusting parameters. This paper puts forward a new method of relief display based on mathematical morphology. Aiming at anti-noise, mean square error of detection results and peak signal-to-noise ratio, the project implements morphology calculation characteristic, combines different morphology operator and improves the given morphology edge detection algorithm. Then, this scheme applies nonlinear processing ability of mathematical morphology and advantages of effectively processing image geometry to use structure element in special structure to obtain relief display effect of image in its fundamental morphology corrosion and expansion edge detection operator. Compared to generalized fuzzy operator of relief display method of images, the method proposed in this paper can obtain better relief display effect and anti-noise.

In the processing of large data of unsteady Web page data or non first sequence Web page data, we often choose the empirical mode decomposition (EMD), typically exhibiting very high noise ratio. Using EMD to the sequence data for processing, and finally get the intrinsic mode function (IMF) and residual series, among them, there existing the local characteristic data of different time range in the intrinsic mode function, showing the property of removing impurities. The use of the characteristic of different IMF covers, obtained the initial Web page information by using the decomposition of the EMD to extract the relevant information from the Web page, for the different features of the IMF selecting different Web page information weight, then using the Euclidean distance to analysis in the similar level. The finally situation shows that using the intrinsic mode function compared with the previous way of matching directly, the former emphasizing on time series decomposition, to eliminate the influence of the noise, and then being matched by using a weighted processing idea, which makes the matching accuracy have a great promotion, this method is effective.

Spina Gleditsiae is the herbal medicine traditionally used in Chinese Medicine for the treatment of human cancers. Though significant progress has been made toward our understanding of the antitumour mechanisms of Spina Gleditsiae, its anticancer chemical information remains unclear. In this study, we used computer-based chromatographic and spectral techniques to isolate and identify nine compounds including fustin(1), (+) trans-2R, 3R-3', 4', 5, 7-tetrahydroxyflavanonol (2), 8-C-glucopyranosyl-3, 4', 7-trihydroxyflavone (3), dihydrokaempferol (4), 5-methoxy-3', 4', 7'-trihydroxydihydroflavonol (5), 5, 3', 4', trimethoxy-7-hydroxydihydroflavonol (6), betulin (7), ß-sitosterol (8) and 2ß-carboxyl, 3ß-hydroxyl-norlupA (1)-20(29)-en-28-oic acid (9) from Spina Gleditsiae. Moreover, their anticancer effects were firstly confirmed on hepatoblastoma HepG2, oesophageal carcinoma EC109 and lung adenocarcinoma A549 cell lines in vitro. Our results provide a theoretical basis for the potential therapeutic use of Spina Gleditsiae in the treatment of malignancies.

This paper presents a compact ultra-wide band (UWB) band-pass filter (BPF) with a notch band based on single coplanar wave guide (CPW) and defected ground structure (DGS), which can effectively restrain the electromagnetic interference between systems and be integrated easily, to ensure immunity and miniaturization of the system. The proposed filter realizes UWB property using a couple of inter-digital coupled-lines and micro-strip line, whose ground layer is located at both sides of the micro-strip inter-digital structure. A couple of spiral rings are respectively embedded on the two ground layer, which gets the adjustable notch band, thereby gaining the dual band. Experiment results demonstrated that the bandwidth of filter designed is from 2.2 to 11.8 GHz (-3 dB bandwidth), fractional bandwidth of 137% at the central frequency 7 GHz and the notch band can be changed optionally from 5.01 to 10.26 GHz.

Carbon deposition has complicated composition and is with a large number of particles, it is very difficult to be removed in the process of remanufacture cleaning. The mixed salt of potassium nitrate and sodium nitrite is used to clean the carbon deposition as cleaning medium, weighing method was used to quantify the effect of cleaning. At the same temperature and washing time, the best cleaning process was sought by changing the formula of the molten salt. Experimental results show that it is more appropriate when the mass fraction of NaOH is in 30%, in this case, the cleaning quality and economic benefit are the best.

With both analytical and numerical methods, chaotic motions of a clamped thin circular elastic plate in coupling fields are investigated in this paper. The chaotic motions arising from the transverse intersections of the stable and unstable manifolds of the heteroclinic orbits are analyzed by means of Melnikov method. The critical curves separating the chaotic and non-chaotic regions are obtained. The chaotic feature on the system parameters are discussed in detail. Some new dynamical phenomena are presented. Numerical simulations are also given, which verify the analytical results.
