摘要：
Hyperspectral data have the characteristics of massive data and high dimensions, which lead lots of difficulties for spectrum analyzing and processing. Especially spectral feature extraction and analysis are the foundation of further processing. In this paper, we discuss a number of spectral data processing algorithms for spectral feature extraction and analysis. The main contribution is that we combine both Douglas-Pcucker (DP) algorithm and spectrum derivative algorithm to extract spectral absorption characteristics from the rock and mineral spectral data. The experiments indicate effectiveness while using the proposed algorithms for spectral feature extraction.

摘要：
It is shown that the RHIC energy-scan experiments can serve as an effective tool for studying the system evolution along the first-order phase transition line passing the critical point, which is a second-order phase transition process. During this process the system structure changes while passing the critical point, and correspondingly, the transverse momentum of the final state particles gets an extra component. This phenomenon can provide useful information about the system structure in different phases and can serve as an effective signal for locating the critical point.

摘要：
As the Internet of Things is proposed, people have increasing demand on the intelligentize of devices. Therefore, how to achieve the interconnection between the Internet and WSN becomes a hot topic of research. This article discusses the implementation of Web Server based on HTTP protocol and analyses the operational theory of the AJAX script. Then a dynamic Web server based on ARM9 hardware platform and Linux software is achieved, in which the dynamic interactivity between the browser and the Web Server is realized. Considering the application of ZigBee in remote monitoring, the design of ZigBee Gateway as a Web server based on Linux and ARM9 is researched. Finally, it is verified in the experiment.

摘要：
Applying the AdS/CFT correspondence,the expansion of the heavy-quark potential of N = 4 supersymmetric Yang-Mills theory at large N c is carried out to the next-leading term in the large ’t Hooft coupling at zero temperature.The strong coupling corresponds to the semi-classical expansion of the stringsigma model,the gravity dual of the Wilson loop operator,with the next-leading term expressed in terms of functional determinants of fluctuations.The singularities of these determinants are examined and their contributions are evaluated numerically.We find the next-leading order correction is negative and suppressed by minus square root of the ’t Hooft coupling relative to the leading order.
