Integer ambiguity resolution is the key technology for attitude determination system via GPS double difference carrier phase observables. In this paper, an efficient and improved LAMBDA method is proposed to search for the correct integer ambiguities. This method is based on sequential conditional leastsquare adjustment estimation. The integer Gauss-transformation is carried out to reduce actual and higher correlation of integer ambiguities, and then the decorrelated ambiguities are searched in the shrinking search space. A comparison is given to demonstrate that this scheme gives a faster search time in determining the fixed integer ambiguities. In addition, the static experimental results show that the proposed algorithm is feasible and efficient for GPS attitude determination system.

The increasing demand for multimedia content incur 58.6% of the Internet traffic during the peak period in North America as of 2012. To better accommodate the demand, the computing power and networking components in data centres are being upgraded regularly, leading to higher energy bills. Among many works on energy efficiency, very little attention has been paid in making multimedia streaming systems energy efficient. In this paper, we propose E 2 Stream, an energy-efficient multimedia streaming system. Unlike existing proposals, E 2 Stream utilizes resources in both the data-centre and end-user devices in order to reduce the power consumed by the entire streaming system. Our evaluation results, based on energy profiles from real devices, show that E 2 Stream can dynamically choose energy-efficient source to stream the content, which effectively reduces the energy consumptions among end-user devices and routers involved in the streaming session.

Semantic Gap problem is the essence of the SQL Injection Attacks vulnerability in Web applications. Web application loses the semantic information while the SQL statement is constructed dynamically. This paper analyzes the cause of the SQLIA vulnerability. And then it analyzes several suggested techniques, such as the filtering techniques and the static analysis, and points out their drawbacks in the SOLIA prevention, which leads to the conclusion that the key problem for the eradication of SQLIA is to solve the semantic gap problem causing by the unstructured SQL statement in the process of constructing a Web system dynamically.
