Multimodal identification, which exploits biometric information from more than one biometric modality, is more secure and reliable than unimodal identification. Face recognition and fingerprint recognition have received a lot of attention in recent years for their unique advantages. However, how to integrate these two modalities and develop an effective multimodal identification system are still challenging problems. Hetero-associative memory (HAM) models store some patterns that can be reliably retrieved from other patterns in a robust way. Therefore, in this paper, face and fingerprint biometric features are integrated by the use of a hetero-associative memory method for multimodal identification. The proposed multimodal identification system can integrate face and fingerprint biometric features at feature level when the system converges to the state of asymptotic stability. In experiment 1, the predicted fingerprint by inputting an authorized user’s face is compared with the real fingerprint, and the matching rate of each group is higher than the given threshold. In experiment 2 and experiment 3, the predicted fingerprint by inputting the face of an unauthorized user and the stealing authorized user’s face is compared with its real fingerprint input, respectively, and the matching rate of each group is lower than the given threshold. The experimental results prove the feasibility of the proposed multimodal identification system.

The multilevel experimental teaching pattern which is based on the blended learning can effectively cultivate the innovation ability of students, and it has achieved good results in practice.
In this paper, we study the implements a data rate can be adjusted, m series can be equipped with pseudo-random series of sequence generator. This design in the basis of linear feedback shift register, through the linear feedback function to produce mould the longest m sequence. In order to carry on it, we use the hardware description language VHDL, take advantage of the FPGA reconfigurability and flexibility, using Quartus II 8.0 for the integrated wiring, and give the Model simulation waveforms. For the sake of verifying the feasibility of this design, we adapt it to the DE2 board, and with an oscilloscope and other equipment were tested.
This paper takes Chengdu residents as the object of investigation, to explore which contents of travel blogs influence their travel decision-making to Thailand. By recruiting 43 Chengdu residents as research objects, this paper analyzes the contents of blogs that affect their travel decisions after reading 5 Thailand travel blogs and relevant questionnaires. Finally, through the questionnaire of Chengdu residents, the content of the online travel information mainly affecting Chengdu residents' travel to Thailand is obtained. Conclusions are: Tourists think that the most influential content of travel blogs for their decision-making is tour routes and itinerary arrangements, followed by traffic information, safety precautions, fees, cultural customs, accommodation information, food and beverage information, etc. tourists are more interested local specialties in food and beverage information, and tourists also show great concern about the description of the characteristic culture. Literature ReviewAt present, the research on travel blogs at home and abroad mainly focuses on the image perception of tourist destinations [5][6][7], the network structure of tourism flow[8-10]and the analysis of the role of tourism marketing [11][12][13]. Among them, the construction of the image of tourist destination based on the travel blogs is the focus of scholars in recent years. For example, Wang Lina and Li Hua analyzed the contents of the English travel blogs of foreign tourists, and used the method of rooted theory to analyze the logical relationship between the sources of negative perception of the image of Chinese tourist destinations. Travel blogs is a way to tell the tourist's travel experience in a story-telling way, and this kind of story-rich blog can promote the potential tourists to become real tourists [14]. Some scholars point out that tourists attach great importance to the traffic, accommodation facilities, food and catering in the contents of the travel blogs, and have a greater impact on the behavior of travel decision-making [3]. However, the relevant research are still lacking, the research on the tourist behavior under the travel blogs needs to be further deepened.
Due to multipath noise pollution, SAS image consists of two parts : target and noise .They can be described by K + K mixture distribution . How to separate noise data which obey K distribution from the target which also obeys K is a hot topic in SAS image field. This paper used the minimum error probability Bayes classifier to solve this problem, and achieved good results. At the same time, this paper also studied the factors that affect the classification results, such as the absolute value difference of training sample parameters and K distribution parameters.

Abstract.With the rapid development of internet and mobile internet, the survival and development of media have been hammered. The paper media needs to seek a way out. This paper analyzes the current situation and dilemma of the paper media, compares the paper media and the new media, expounds the reading habits and psychological of readers in the mobile internet era and explores the marketing strategies of paper media development. Current Situation and Dilemma of Paper MediaThe paper media refers to the traditional sense of the newspapers, magazines and other media with the paper as the carrier. From the birth date, paper media has a long history. In history, it has a glorious achievement, plays an important role in people's life, work and study. China's newspaper media includes party newspaper, city newspaper, professional newspaper and regional newspapers etc. The magazine can be divided into two categories: comprehensive periodical and professional periodical. New media is using digital technology, network technology, through the Internet, broadband local area network, wireless communication network, satellite channels, and computers, mobile phones, digital TV terminal to provide users with information and entertainment services communication form.In recent years, with the rapid development of internet and mobile internet, the survival and development of media have been hammered. People's reading habits have changed.A part of the group losesinterest in the paper media, leading to a sharp drop in the number of paper readers. Today's paper media is faced with the cost of printing and issuing way is single; the propagation speed is slow, high labor costs, advertising revenue decline and other issues. In the past few years, some newspapers have failed to survive the cold winter of 2015.Zawenbao under the Hebei Daily newspaper industry shut down in January 2015. The Xinbao in Hong Kong which has nearly 60 years of history went bankrupt in July2015. Shanghai quantity issued biggest business daily "Shanghai Business" in October 2015 officially closed. Throughout the north and south, a lot of media have made changes and adjustments. In October 2015, the Southern Metropolis Daily started the new century twelfth revision. In the same month, the Chongqing Morning Post published revised declaration, announced on November, embrace change. Shenyang Evening News launched to raise the public. Under the background of "Internet plus", paper media is in face of big development challenges, needing to seek a phoenix road. Comparison between Paper Media and New MediaThe development of new media doesnot mean that the traditional paper mediadoesn't have any advantages. In fact, paper media and new media have their own strengths and weaknesses and theyhave their own advantages and shortcomings. The table shows the paper media and new media in the professional degree,
