Authors: Li Nian , Peng Qing Xi , Yin Li , Wang Li Ping
Published: May 2014

With development of Internet, an increasing number of user-generated-contents provide valuable information to the public. Microblog is a new platform where peoples discuss all kinds of topics. It also provides a good opportunity for the researchers to explore the online public opinion. News collection and summarization has been attracted lots of research previously. However, manually labeling is impossible since the task is time-consuming. In this paper, we focus on news summarization with few labeled samples. A semi-supervised learning method has been proposed to tackle the problem. We employ Co-Training method to extract the news information. Posts and replies of Microblog have been identified as two independent views to train a classification model. Entity, Time, place and incident of news have been identified as well. Experimental result in different datasets shows the proposed method outperform the baseline methods.

EIWCS: Characterizing Edges Importance to Weaken Community Structure
Authors: Lei Fang Yuan , Cai Jun
Published: May 2014

Edges in a network can be divided into two kinds according to their different roles when removed from the network: some enhance the community structure like the ones connecting two communities while others contribute to weaken the community structure like the ones inside a community. In this paper, we define the edge important to weaken community structure as the relative change in the eigenvalues of the network adjacency matrix upon their removal, which is called EIWCS. Experimental results on real-world network and artificial networks indicate the EIWCS index can well characterize edges important to weaken community structure.

Authors: Wang Xiao Ming , Zhu Sheng , Cui Jian Zhong , Chang Qing , Zhu Qing Feng
Published: May 2014

To develop high wear-resistant protective materials for magnesium alloy, high-silica Al-based alloy modified via P-element was fabricated by DC casting method. Microstructure of ingot samples was observed by using optical microscopy (OM), etc. The results demonstrated that Al-Si-0.01%P alloy with unique microstructure and without defects such as voids and rarefaction might be generated by processing control. Owing to modification by Al-P interalloy, primary crystal silicon phase in hypereutectic Al-Si alloy were refined effectively. Its size in Al-18Si-0.01%P alloy decreased from 50μm to 20μm, and distributed uniquely than that in Al-18Si alloy. Al-P acted as heterogeneous core of primary crystal silicon phase, which was the main mechanism for Al-P interalloy to modify primary crystal silicon in Al-Si alloy.

Authors: Pham Son Tung , Prince William
Published: May 2014

The objective of this work was to examine the influence of carbonation on the microstructure of cement materials. Different materials, which were CEM I mortar and paste, CEM II mortar and paste, were carbonated at 20°C, 65% relative humidity and 20% of CO2 concentration. The specific surface area and pore size distribution were determined from the method of nitrogen adsorption. The results showed that the materials based on CEM II seemed to be more sensible to a creation of mesoporosity after carbonation than the CEM I based materials. The results of this study also helped to explain why observations in the literature diverge greatly on the influence of carbonation on specific surface area.

Published: May 2014

Digital watermarking technology has already been used for secure data aggregation in wireless sensor networks. However, most of the existing watermarking technologies are irreversible, and the embedded watermark will cause some damage to the data collected by sensors. In this paper, we proposed a novel distributed reversible watermarking technology based on an improved difference expansion scheme. Due to the hierarchical clustering architecture organized according to LEACH protocol, a distributed self-organized mechanism is established within clusters for the watermark generation. The whole watermark is split into several segments and the watermark segments are assigned randomly to different sensors within a group. In addition, a pair of synchronized random sequence generators is applied on both the sensors and the sink to fresh the data.

This paper established an effective water treatment technique using Abelmoschusmoschatu (Okra) in combining of glue extraction process and flocculating process, with fully consideration of factors such as treating time, cost, and efficiency. Results showed that ethanol extraction was an effective method for extraction of glue form Okra. After being soaked in distilled water overnight with ratios of material to solvent, and was extracted by ethanol with volume percentage of 50% at stable temperature of 70 °C for one hour, the extraction rate of Okra glue could be as high as 18.38%. The glue usage of 0.015-0.020 g.L-1 and flocculating time of five minutes could be the optimal usage in treating suspending liquid of kaolin, with the turbidity of 3.0 g.L-1. The processes are low cost, simple, efficient, and low pollution, having broad application prospects.
A Partial Histogram Maintenance Mode
Authors: Lin Xu Dong
Published: May 2014

Although histogram has been introduced into the optimizer of the relational database to assist cardinality estimates for more than thirty years, the issue of histogram maintenance is not addressed well. The application of the query feedback information provides a new way of thinking for the histogram maintenance. But it is not mature until now and inefficiency is the main problem. The query feedback-based histogram maintenance approach adopts the entire update mode and the whole histogram will be updated in each maintenance process. This mode brings huge computation for the maintenance process and becomes the most important reason for its inefficiency. Therefore, we propose the partial update mode in this paper to replace the entire update mode and try to improve the maintenance efficiency by limiting the updating range and decreasing the computation in each maintenance process.

Published: May 2014

Grasslands are the important supplementary source of food. Shear strength at high soil bulk density grassland was studied to improve the traction performance and develop the crop yield. Shear force and shear displacement are tested at different vertical loads. Results indicated that with the increasing of shear displacement, shear force was found to show a parabolic trend of first increasing then decreasing. Moreover, larger vertical load would lead to steeper shear force curve against shear displacement. It also should be noted that, the maximum shear stress showed a parabolic increase trend following the increasing of the normal stress. This is the theoretical basis of matching appropriately tractor and implement system to maximize the traction performance and reduce tire slip.

In this paper, low temperature oxygen plasma treatment method was adopted to process the carbon fiber surface. Flexural Strength test method was utilized to represent f composite material flexural strength. This paper observed flexural failure morphology of composite material by aid of SEM, then it compared the mechanical property, hygroscopicitiy and flexural strength retention rate of composite material before and after the plasma treatment. Results showed that the optimum treatment conditions of carbon fiber were 300W treatment power and 15-minute treatment time. Under the condition, the highest flexural strength value be increased by 19.55%.Saturated bibulous is low and bibulous rate is slow, flexural strength retention rate is 94.9%. And at the same time PES-C resin matrix can be strengthened, which will further improve the mechanical properties of composite materials.
