It is very important to study LBS (Location-based Service) personal location inference for the privacy protection and the value extraction of LBS big data. According to study the characteristics of the target user’s state in day view belongs to Gaussian distribution, an effective method to infer the user's home and work location is proposed in the article. Experimental results show that the inference...
The growth of the Internet and online social media, especially in recent years, also gave rise to a proliferation of online multimedia content creation and distribution. The use of modern steganography methods - the art of hiding information within multimedia - presents an unprecedented opportunity for malicious uses of these materials. Therefore, developing an effective technique to avoid the distribution...
Currently there are many problems in the engineering education in China, mostly due to that the collaborations between universities and enterprises are so insufficient that the students are always lack of necessary engineering practice. Consequently, reformation of engineering education is needed in order to address this issue, in the background of which the project discussed in this paper is carried...
P2P systems can be used to form a low latency decentralized data delivery system. Structured P2P systems provide both low latency and excellent load balance with uniform query and data distributions, however, in the real application environment, requests distributions are often skewed and follow a Zipf law, some objects will become hotspots, individual nodes are easily overloaded, resulting in poor...
The objective of this study is to establish a cellular model for investigating the relationship between Alzheimer's disease and it's risk factors. The full length cDNA fragment of Swedish-type mutated APP695 (APP695sw) was amplified by PCR and ligated into pcDNA3.1(+) vector to construct the recombinant plasmid pcDNA3.1-APP695sw. The SH-SY5Y neuroblastoma cells were transfected with pcDNA3.1-APP695sw...
Application relay is important for many delay-sensitive applications such as voice over Internet protocol (VoIP). It has been proved that relay selection would be optimized considering autonomous domains (ASes) relationship. We describe a new method for relay selection using service discovery in distributed hash table(DHT) in which relay service advertisements are indexed and clustered according to...
