Published: September 2013

Topic Map, which described as The GPS of information universe, traditionally focused on building knowledge structure and associating them with information resources. In online-education environment, it has been used to address the issues about people disoriented in huge amounts of learning resources, to support learners browse the semantic relationship between knowledge topics and find the learning content effectively and instructors externalize their implicit knowledge both on conceptual and information level. However, as the explosion of knowledge information, people are suffering the disorientation of knowledge topics. Specially, learners are puzzled about what knowledge are valuable and need to learn, and knowledge providers dont know how to update outdated knowledge hierarchy or develop new knowledge product for changing requirements. To address this problem, we extend Topic map by adding a top level, named knowledge requirement level (KRL). This level KRL can be used to guide learners to concentrate on the required knowledge topics, and drive knowledge providers to redevelop or refactor outdated knowledge hierarchy. In order to obtaining social knowledge topic requirement for KRL, we have developed an information extraction tool, named WIE, to extract knowledge requirement information from job-list Webpages for supporting users extract data for different piece of a given structure-fixed Webpages.

Authors: Wang Feng , Sun Cui Hua
Published: September 2013

Realization of big Deep Web database optimized access with low sample deviation was researched. With the sharp increasing of the storage of Deep Web database geometrically, the problem of optimized access to the database was becoming difficult. On the basis of correlation feature rule extraction, an improved optimized access method for the Deep Web database was proposed based on Graph Model Sample process and correlation rule. The access was realized by computer simulation. The access process was started with the arbitrary effective result as the access starting line. The access result was returned, and the records were obtained in the returned web page. The next query and access was implemented with the local sample database for the nest access start line. The method avoided the effects of the query interface properties. And the Graph Model Sample method could overcome the limitation of the query interface properties. Also the correlation feature extraction algorithm was researched, and it was used as the access rule in the database for the realization of optimized and efficient query. The simulation result shows that the sample deviation is stable with the value about 10% for the simulated Deep Web database. The relevant sample deviation value is trended to convergence and is near to the real value with the increasing of the access number. According to the realistic Web database, the sample bias estimation mean value is about 21% which is higher than the simulated database. Two typical Deep Web databases are taken as the researching objects, with the new method, and the access bias is lower than another Web database which without using the proposed method, result shows nice performance of the proposed optimized database access method in application.

The system uses dual MCU design to achieve the acquisition and transmission of pulse signal without affecting the users sleeping process. The pulse signal is collected by infrared pulse sensor, and is wireless transferred to the personal computer by JF24C after the process of amplification, baseline correction and so on. Then personal computer analyses the signal using the method of wavelet transform algorithm. With wavelet decomposition, pulse signal can be decomposed into different scales of wavelet coefficients and recomposed according to the low-frequency coefficient of the bottom and high-frequency coefficients of various layers. During the process of wave recomposition , the coefficients related to noise can be rejected while the valuable information in the pulse signal maintained, and all the processes achieve the restoration of pulse signal. What is more, after simulating the wavelet transform algorithm using MATLAB, the consequences of this simulation indicate that multiple interferences can be effectively suppressed while keeping the pulse signal undistorted and it sustains the relevant characteristics of pulse signal.

Published: September 2013

In this article we focus on SIP session setup delay .It bases on adaptive RLP retransmission mechanism in the previous paper.It proposes a way used RLP retransmission strategy combined with the performance of wireless channels, that i s to say in different chain Road conditions use different RLP retransmission strategy approach. This method not only can complete the RLP adaptive retransmission of SIP messages at the link layer, and can select the appropriate link status of the different RLP retransmission strategy, thus effectively shortening the SIP session establishment delay, end to end QoS for IMS performance improvement. After a simulation experiment, the effectiveness of the proposed algorithm is tested.

Image processing is a type of memory-access-intensive application which puts a great pressure on memory access speed and bandwidth. Memristors has the ability of both memory and computing. With this property, we have designed and implemented image logic operations in memristor memory system, which could save a large amount of memory access at relatively low memory space price. Based on this work, we use image logic operations with memristors into edge detection of binary image. The main idea is as follows. First, we use XOR operation of neighboring pixels to determine whether there is an edge and get the vertical edges and horizontal edges, respectively. Then, we combine the edges in two directions to obtain the whole edge image of the original image. The experimental results show that, our design is right in function, and could reduce memory access considerably.

Authors: Shi Zhi Yuan , Zhang Chang Zheng , Zhao Cai Dan , Huang Lian Fen , Zhao Yi Feng
Published: September 2013

Authentication is the process where claims of identity are verified. Most mechanisms of authentication exist above the physical layer, though some exist at the physical layer often with an additional cost in bandwidth. This paper introduces a general analysis and design framework for authentication at the physical layer where the authentication information is transmitted synchronously with the data. By superimposing a carefully designed secret modulation (wavelet transform) on the waveforms, authentication is added to the signal without requiring additional bandwidth. Simulation results are given that demonstrate the potential application of this authentication technique.

Published: September 2013

We focus on the recognition of RS code in a reverse-engineering communication system, and an algorithm based on spectral statistic is proposed, which makes use of the spectral characteristics of RS code. When there are some codes with errors in the observations, the spectral histogram statistic is computed, which can improve the probability of detection in the noisy environment. Experimental results are given to illustrate the performances of the method which can get a 90% probability of detection of (255, 223) RS code in the presence of 0.5% code error rate.

Published: September 2013

Aiming at avoiding misregistration in complicated medical image registration based on SURF (Speed-Up Robust Features)-TPS (Thin-Plate Spline), we propose a novel algorithm. This method is based on SURF and human interaction method for feature extraction. Then we improve SURF-TPS and propose an algorithm named TPS-SEMISURF which obtains the deformation field by calculating the Thin-plate spline of the feature points, and finally does the medical image non-rigid registration according to the parameters. Experimental results showed that the proposed method can register medical images effectively. It has a good robustness and owns better precision and rate than traditional algorithm.

Polyphase FIR filters are applied in many practical Digital Signal Processing applications where the sampling rate needs to be changed. This paper focuses on the implementation of polyphase square root raised cosine (SRRC) FIR filter based on Field Programmable Gate Array (FPGA). The filter employs methods like filter's multiphase structure, symmetrical coefficients, I/Q channel multiplexing, pipeline addition and so on to design the SRRC filter.
