Authors: Hao Lin , Zhang Yong Shun , Li Zhe , Xu Jie
Published: July 2014

For the issue of MIMO airborne radar clutter modeling in different environment conditions, a clutter modeling method based on composite model is proposed. It builds different types of clutter model through the changes of model parameters. The clutter model consists of clutter amplitude distribution model, and clutter cell scattering model. After considering the error factors such as element error, channel error, clutter fluctuation, a clutter modeling method based on composite model under error conditions is proposed. Finally, the computer simulation is made about the amplitude, the back-scatter coefficient, error factors, the space-time MV spectrum and the characteristic spectrum of different types of clutter through changing the model parameters. The simulation results show that: In ideal conditions, the Clutter Spectrum has good space-time characteristic, but in error conditions, the clutter fluctuates tempestuously, and in different environment conditions the fluctuation degree is different.

Published: July 2014

Faced with complex electromagnetic environment and varieties of adaptive radar waveforms, radar signal analysis and identification becomes more and more complex. Considering two important physical quantities - time and frequency in modern signal processing methods, this paper proposes that the joint time-frequency analysis (JTFA) method based on fractional Fourier transform (FrFT) and short-time Fourier transform (STFT) is applied to adaptive radar signal processing. The simulation results show that the joint time-frequency analysis method is superior to single short-time Fourier transform, getting a better analysis of results. The joint time-frequency analysis method provides the joint distribution of the time domain and frequency domain for adaptive radar signal analysis and describes the relationship between signal frequency and time.

A Robust Image Preprocessing Algorithm for Face Recognition
Authors: Wang Yan , Li Zhao Kui
Published: July 2014

In order to obtain more robust face recognition results, the paper proposes an image preprocessing method based on average gradient angle (AGA). It is based on the fact that the central pixel and its neighbors are similar in the local window of an image. AGA firstly calculates the ratio between the relative intensity differences of a current pixel against its neighbors and the number of its neighbors, then employs the arctangent function on the ratio. The dimensionality of the AGA image is reduced by linear discriminant analysis to yield a low-dimensional feature vector. Experimental results show that the proposed method achieves more robust results in comparison with state-of-the-art methods in AR face database.

To solve these issues, home network is proposed to connect all the appliances, home PC and portable devices together using network technology. Controlling all the appliances through one single node ( the home network gateway), home network makes life much simpler and convenient. There are several local area network technologies applicable to home network. Bluetooth technology is chosen in this paper as the home networking technology due to its many advantages over others. The implementation scheme of home control sub-network based on Bluetooth serial part profile ( SPP) and the standards of Home Network Platform in China is proposed. According to actual application fields, the communication protocol architecture for this scheme is established by using appliance control protocol promoted by the manufacturers and universal device control protocol ( UDCP) over SPP. Many management functions of appliance terminals are realized such as appending, login, operation, logout and alarming. Implementation methods of appliance terminal based on an entirely embedded single-chip manner and mobile control terminal which is realized by computer simulation are proposed.

Authors: Du Fang , Peng Liang Fu
Published: July 2014

The layered LiNi0.4Co0.2Mn0.4O2was synthesized by co-precipitation method using carbonate sodium as precipitant. The microscopic structural features and morphologies of as-prepared cathode materials were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). And then, the charge-discharge measurements were carried out to determine the electrochemical properties in a voltage range of 2.5-4.6 V. The results show that the pH value in the process of co-precipitation reaction plays a greater part on the electrochemical properties than feed rate does. The cathode materials prepared at higher pH value illustrate better electrochemical properties in the voltage range of 2.5-4.6 V, which can be attributed to a less cation mixing in the cathode material as well as the smaller primary particles and the smaller second particles.

Nowadays the recommendation system has been widely used, especially in the field of e-commerce, SNS, music, etc. On the basis of recommendation systems which are widely used, the paper puts forward a theatre recommendation algorithm which is more suitable in the field of theatre. In order to achieve the recommendation of theatre, the paper uses a series of steps, including weight, bipartite graph, data standardization, similarity calculation. After using this algorithm, some theatres will be recommended according to recommendation level. The results of recommendation are more reasonable, effective and satisfied.
Creating a New Combined Influence Measure: An Analysis of the Citation Network
Authors: Deng Rui
Published: July 2014

This paper utilizes social network analysis to create a comprehensive evolution system to determine the significance of research papers. Citation network was analyzed from H-index, Impact factor and relative citation rate, which indicates the influence of the author, published journal and the paper on the field respectively. Influence citation network was built visually though transforming the 16 science network paper’s citation multi-value matrix into two-value matrix in UCINET and by analyzing those influence measures, the scores of each paper were calculated and results maps through visualization. The results concern: the paper of Collective dynamics of `small-world' networks laid a foundation on network science. Besides, a general methodology is provided to determine the role or influence measure of academic journals.

A Fuzzy Trust Model for Public Key Distribution in Body Area Networks
Authors: Wu Guo Wei , Liu Zuo Song , Pirozmand Poria
Published: July 2014

It is now possible to implant a network of sensors inside the human body for monitoring the human body functions and the surrounding environment. In a body area network (BAN), the confidentiality and integrity of the sensitive health information are particularly important. The key establishment is thus a fundamental security service in BANs. To guarantee validity of the key and avoid misbehavior of self-ish nodes, we propose a fuzzy trust model for public key queries in BANs. Every user accesses the public keys of other nodes from those trusted neighbors rather than all of its neighbors. The proposed trust model uses fuzzy sets to calculate every node’s trust value. Our trust model exploits multiple metrics rather than a single metric, and converts them into a single numerical ranking. We perform an extensive evaluation of the proposed approach. The results indicate that our trust model can not only identify abnormal nodes’ behaviors, but can also reduce query traffic while improving the reliability of the returned public keys.
Topic-Oriented Information Retrieval

Published: July 2014

With the rapid development of Internet, more and more information has been displayed to people. More and more researcher pay more attention to how to find useful information from this huge information ocean. We design the topic-oriented information retrieval system in order to overcome the drawback of generic crawler. The system retrieves topic information efficiently and helps user get useful information rapidly and exactly.

A Database Grid Service with a Novel Mutation Operator
Authors: Cao Jian , Li Yan Bin , Yan Cong
Published: July 2014

Database grid service provides users with a unified interface to access to distributed heterogeneous databases resources. To overcome the weakness of collaborative services ability in different grid portal, a new grid portal architecture based on CSGPA (Collaborative Services Grid Portal Architecture), is proposed. This paper aims to enhance the performance of PSO in complex optimization problems and proposes an improved PSO variant by incorporating a novel mutation operator. Experimental studies on some well-known benchmark problems show that our approach achieves promising results.
