Nowadays, most websites provide tremendous information organized in complex structures of web pages. Therefore, how to help users quickly find pages they are looking for is an important issue. Although a sitemap can provide navigation information

across sections

of the website, it is static and can hardly provide dynamic information based on access patterns and browsing trends. In this paper, we proposed a hybrid approach for improving recommendation ranking of the web pages for the next visit. Our raking strategy considers not only the relevance (correlation to the next page calculated by the collaborative filtering algorithm) but also the level of interest (time spent on a page) and accessibility (the distance to the next page). In order to evaluate the proposed recommendation ranking algorithm, we used the web access log (IIS log) of a website, Health 99, operated by the Bureau of Health Promotion, Taiwan. The log data was divided into training and testing sets. The measurements of the relevance, the level of interest and the distance factor were computed from the training set. The experimental results showed that the possibility of the pages in the recommendation ranking lists by our approach that were accepted by users was much higher than that proposed by the original collaborative filtering algorithm, particular in short recommendation list (< 5).

The fruit ripening of Green-ripe (Gr) mutant tomato was inhibited dramatically. To determine the expression patterns of Gr in tomato, we first produced the polyclonal antibody of Gr protein. RT-PCR was used to amplify the Gr gene from green ripe tomato fruit. And the PCR product was subcloned into prokaryotic protein expression vectors pET-30a to generate recombinant plasmid. The Gr protein was induced by IPTG in BL21 (DE3) and purified by Ni-NTA agarose column. The anti-Gr serum was produced by immunizing rabbits, and the titer of the anti-Gr serum was above 5000 by ELISA analysis. Purified by the DEAE-52 ion-column, the high purification level of anti-Gr polyclonal antibody was obtained. Furthermore, RT-CPR was used in the RNA level to demonstrate that the expression of Gr gene was specialized in some cultures of tomato. For example, the expressions of Gr were higher in seed, flower and green ripe fruit than others, and the expression level were reduced by exogenous ethylene treatment in the flower and green ripe fruit. Moreover, Polyclonal antibody of Gr was used to investigate the expression pattern of Gr in protein level by the Western blotting. Our results show that the expression level of Gr in protein level was complied with the expressions in RNA. So, we suggested that the regulation of Gr was transcriptional.

In mobile Ad hoc networks (MANETs), several nodes’ uncooperative behaviors would significantly affect the overall performance and the security of the networks. Reputation systems have been proved to be efficient to block such behaviors. However, they failed to resist the collusion attacks of malicious nodes. A novel reputation model based on subjective logic was proposed in this paper in order to detect malicious nodes efficiently even when they colluded to interfere with the reputation assistant mechanism. The concept of opinion distance was introduced to filter malicious recommendations so that the false accusations laid by malicious nodes would have little influence on the performance of the reputation model. Simulations were conducted to evaluate the proposed model on its performance. The results indicate that it performs much better than other similar models in detecting malicious nodes, especially when malicious colluding behaviors exist in the MANETs.

With significant accomplishments of wireless communication, mobile collaborative applications indispensably and inevitably become a new trend. Traditional context aware applications are not directly practicable to current mobile collaborative environments because: 1) Traditional context-aware applications mainly aim at one single user. But in a collaborative environment, the object is a group of users. 2) Traditional context-aware services are always static. In a mobile environment, however, context aware services keep on continuously changing. Fixed communication mode also changes into collaboration in motion. In this paper, a context-aware organization model for mobile collaboration and its management mechanism are proposed. We also introduce a collaborative recommend strategy based on above model. At last, the strategies we proposed are implemented in the Location Aware Mobile Cooperative System (LaMOC) system.

Hybrid in-band on-channel (IBOC) broadcasting system as a scheme of digital audio radio could transmit analog FM and digital audio simultaneously. In IBOC systems, broadcasters transmit signals within the allocated channel bands, thus the bandwidth assigned for digital audio transmission is very challenging. BICM-ID can improve BER performance over Rayleigh fading channels without bandwidth expansion, thus it is used in FM IBOC and has been verified it can yield a better coding gain. However, conventional IBOC systems apply QPSK as channel modulation scheme, which can not take full advantage of constellation space compared with duobinary modulation. In this paper, various modulation schemes with the same encode rate and the same bandwidth efficiency are compared and analyzed. Simulation results show that advanced modulation scheme can effectively improve the performance of BICM-ID FM IBOC. When BER is below 10

− 6

, 32APSK modulation scheme can achieve more than 1dB coding gains over Rayleigh fading channels.

In his paper, an improved non data aided (NDA) carrier frequency offset (CFO) estimation algorithm for Orthogonal Frequency Division Multiplexing (OFDM) systems was proposed. The proposed algorithm was based on two existed NDA algorithms which were analyzed and their channel models’ assumptions were introduced at the beginning of this paper. The proposed algorithm composed the two algorithms’ cost functions through a adjust factor, which could utilize data information more sufficiently than the two existed algorithms when the two channel assumptions were all satisfied at the same time. When the two channel assumptions could not be satisfied at the same time, the proposed cost function would degenerate to one of the two existed cost function automatically. At last, the simulation results confirmed that the proposed algorithm had better performance in both static channel and time varying multi-path delay channel than the two existed algorithms.

This study tests for the effects of export oriented strategic trade policies on the comparative adv0061ntages of Chinese agro-based manufactured products, which are consisted of 39 SITC (Rev.3) 3-digit products. "Net exports ratio " is employed to capture the strength of strategic trade policies, while "revealed symmetric comparative advantage" is used to measure the comparative advantages. Using yearly data from 1992 to 2008, a heterogeneous panel cointegration test indicates a cointegrating relation across the NX and RSCA panels. No short-run Granger causal relationship of either direction can be identified. In the long-run, however, there exists a bi-directional causality. By examining the coefficients of the first-differenced lagged terms in panel vector error correction models, this study argues that the net exports of Chinese agro-based manufactures are virtually based on the comparative advantages, and the strategic trade policies which are featured by export promotion may contrarily hurt the comparative advantages in the long-run.

The adaptive equalization technique is an effective approach to eliminate the inter-symbol interference (ISI).

Considering this, we have proposed an improved algorithm combined with the coordinate descent method in this paper. The simulation results confirm that the novel algorithm achieves faster convergence rate and lower steady-state errors than the traditional RLS algorithm.

With the wide use of information technology, the ability of young people to write Chinese characters is declining. In order to improve the ability, in the paper, we propose an on-line evaluation approach to the normativity of a handwritten character, which is based on the determination of the relationships between writing sub-strokes by vector cross-product. By comparing the relationships between sub-strokes of a handwritten character with the relevant relationships of a standard character, the method can easily determine whether or not a handwritten character is normative. This approach can be used to automatically evaluate handwritten characters in real time and allow paperless teaching character writing.

In-Band On-Channel(IBOC) digital audio broadcasting(DAB) is a method of digital audio radio, which could transmit analog FM and digital audio simultaneously. However, due to the existence of fading and interference in FM bands, and transmit capacity has reached its limitations for the bandwidth, thus, adding digital transmission availability in the crowded FM band is a challenging proposition. Diversity is one of the crucial techniques for digital transmission. Bit-interleaved coded modulation (BICM) can provide spatial diversity without occupying high bandwidth. Meanwhile, Low Density Parity Check( LDPC) code with low density scheme can be a better choice as IBOC FM system which allows a certain degree of freedom in design, In this paper, a type of coded modulation scheme was proposed in Hybrid in-band on-channel system, by use of BICM embedded into LDPC code is instead of BICM embedded convolutional codes for IBOC FM system, would result in coding gains without bandwidth expansion.

Bit-interleaved coded modulation (BICM) can provide spatial diversity which is one of the key techniques for transmission, and can get better coding gains without increasing the bandwidth. Meanwhile, STBC which is the technique of temporal is applied to raise transmission reliability. In this paper, BICM is utilized to be embedded into spatial division multiplexing of two Alamouti codes, which would lead to coding gains and not increase the bandwidth. The simulation results show when BER is below 10

The ratings-based methodology employed by Socially Responsible Investment (SRI) indices in their selection processes excludes many corporations by creating limited-membership lists. This received ratings-based structure is yet to offer an incentive for most of the excluded corporations to invest in improving their levels of Corporate Social Responsibility (CSR). We, therefore, investigate under what circumstances a ratings-based method for assessing CSR could provide an incentive to firms excluded from SRI indices to invest in CSR. In this article, we attempt to offer a theoretical reply to this question. We argue that when all firms are publicly ranked according to SRI index parameters, such indices can indeed create a market incentive for increased investment by firms in improving their performance in the area of social responsibility. We further show that this incentive tapers off as the amount of investment required exceeds a certain point or if the amount of payback on that investment fails to reach a certain threshold.

In this paper, an efficient depth image based view rendering method for high quality multi-view virtual images synthesis is proposed, which utilizes two color images with their associated depth maps. The proposed method consists of four main steps. The first step is virtual camera parameters design by using shift-sensor camera model to avoid the keystone distortion during virtual view synthesis. Secondly, the mixed color pixels around the boundary of image objects is detected and skipped in the following step, which can eliminate the “ghost” artifacts. Then the two input color images are rendered to multiple virtual view positions on the basis of depth-image-based rendering (DIBR) and merged into one image. Finally, a depth-aided inpainting algorithm is used to fill the disoccluded areas. Experiment results are shown to demonstrate the superior performance of the proposed method compared to other traditional DIBR methods.

According to the basic Proxy Mobile IPv6 (PMIPv6) specification, more resource shall be consumed because of multiple copies of every packet being forwarded to a Mobile Node (MN), which may result in network congestion and some security issues for a MN’s multi- interface sharing a unique network prefix. To tackle the issues and enhance reliability, an integrated binding mechanism is proposed. It can confirm the matching relation between an IF-ID and its IP address for all scenarios which are in lined with a MN’s multi-interface sharing with a unique prefix. The proposed mechanisms are future proof in that they can be used in conjunction with any possible radio access technologies and provide well expansibility. Generally, the time delay which the LMA spends forwarding the first packet to the exact MAG is rather short. Furthermore, the mechanism can apply to more interfaces described in this paper.
