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.
This paper direct to security and real-time requirements in high-speed network transmission processing, based on SOPC technology, design a High throughput AES encryption/ decryption processing unit with pipelining. The design goal is to optimize the hardware structure and improve the throughput, S-box design and parallel processing structure. Compared with traditional AES crypto-chip has faster rate with encryption and less consumption of resources advantages. This design adopts VHDL hardware description language, use Quartus II 8.0 for the synthesis and routing, and this processing unit is packaged an independent IP core, attached to the Altera provided the Nios II system, finally download and test validation on the DE2 development platform.
Student is the subject of the experimental teaching activities, cultivating the ability of independent study and technological innovation is the main aspect in experimental teaching reform. This paper analyzed the problems of traditional teaching model, explored and practiced the multilevel experimental teaching pattern which is based on the blended learning, it made the teachers fully play the leading role, and it fully reflected the subject status of students, it also roused the enthusiasm of students by the use of multi-platforms, media and environments. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
