Abstract: This paper uses the cotton textiles of the cache of Yuan Dynasty unearthed at Longhua Gezidong as an example, combined with some other cotton textiles in Yuan Dynasty unearthed in the whole country, to demonstrate the development of the production areas, product type, weaving and dyeing technology from the Yuan Dynasty cotton textiles. The result shows that the cotton textiles had been founded in many areas, and the dyeing technology and weaving technology of cotton textiles interacted in special way in Yuan Dynasty.

Abstract: With the number of college graduates is increasing year by year, digital information management for the employment of college graduates receives more and more attention of managers in colleges and universities. Establishing management information system of college graduates employment is imperative. In this paper we first discuss the theoretical concept and the common structure model of employment information management system, then according to the demand of college graduates employment and enterprise recruitment requirements design the college graduates employment management system based on Web. The system includes the graduate information management systems, enterprise information management system, recruitment information query system, students landing system. Finally, we test and do simulation on operation of the system. The result shows that the university graduates employment management system has the advantages of simple operation, safe and reliable operation. It builds a platform for the exchange of information among the university, graduates, enterprise, which facilitate the management of graduates.

Abstract: This article through to the Rayleigh channel, les channel and all shadows channel features such as research, put forward the suitable for unified measurement and control system design scheme of downlink signal simulation, by changing the module can be effective simulation of measurement and control environment. The implementation of the system to evaluate the working state of the receiver, troubleshooting, and provided an important tool to find the accident reason.

Abstract: Although the simple structure and easy operation of completing data process depending only on the real-time request of database, the database call time is far longer than the lookup time. If the database is called too frequently, the processing speed will surely be cut down and the real-time performance will be degraded. Based on the situation, this paper will put forward one method, which combined cache with database can improve the performance of the system in the main controller of integrated security system of equipment management.

Abstract: According to the trend of the development of the computer system bus more, designs the general high-speed data storage system based on computer platform structure.Put forward the "one-way chain" cache structure, to avoid the computer operating system of real-time data transmission, the influence of the multithreaded mode data transmission and storage of parallel processing.According to the basic principle of data storage in a computer system, put forward the standard file operations function replace special instruction set, the method of implementing the SCSI disk array storage at a high speed.Test results show that the data storage system based on computer platform with more generalization method to achieve the high speed of data storage.

Abstract: Internet has become as a social infrastructure. The current Internet architecture based on TCP/IP is faced with many challenges. This fact makes the clean slate design of future Internet architecture represented by ICN (Information-Centric Networking) be a hot research topic. In this paper, a novel routing scheme for ICN (Information-Centric Networking) is proposed. On the basis of name-based routing, a process was designed to look for other available interface through which the backtracking-condition-met interest packet will be forwarded, which can reduce the network blocking rate. Moreover, FIB (Forwarding Information Base) of neighbor nodes will be modified when data packets go through a router, which can realize the efficient use of cache. Also, a concept of "popularity" is introduced to improve CS (Content Store) hit rate. The proposed routing scheme is implemented on NSFNET by simulation, and the experimental results have shown that it is feasible and effective.

Abstract: A triple-level-cell (TLC) STT-RAM architecture was proposed basing on parallel MLC MTJ and serial MLC MTJ. A TLC STT-RAM cell can store three bit which will offer higher capacity density compared with SLC STT-RAM. The write process is also analyzed that it contains three types of basic states transitions. Through mapping soft, medium and hard domains to three individual cache lines, the access to soft lines can perform as accessing SLC STT-RAM-based cache. The amount of three-step operations is also much reduced. .

Abstract: In this article we extend the application of ISCSI protocol to the data storage field of mobile device. First of all, we describe the implement principles and advantages of ISCSI protocol, and discuss the problems and solutions in the design. Then we implement the interface design based on the Android platform, port the ISCSI kernel-mode module, and design the ISCSI communication interface for multiple layers of Adroid system. After that we propose a local cache policy based on the linear mapping method of Device mapper. At last, we analyze the impact of the cache policy on the improvement of system performance according to the experiment results. In a word, we supply a feasible storage solution to solve the problem that there is not enough storage capacity in the mobile device and satisfy the instant accesses from users.

Abstract: This paper focuses on the issues of real time ETL based on the semi-structured textural data sources. Because the mapping between text data and relational database relies on object-orient programming language, the paper first implements a text-object-relation mapping model for textual data sources based real-time ETL,and then studies the characteristic of real-time and security of purposed model. The cache mechanism aims to solve the performance difference between object-text mapping and object-relation mapping,and furthermore both encryption and signature mechanism aim to guarantee the security of the data in cache. The theoretical analysis and experiments prove the high efficiency and practicality of the mapping model.

Abstract: Traditional network processors (NPs) adopt either local memory mechanism or cache mechanism as the hierarchical memory structure. The local memory mechanism usually has small on-chip memory space which is not fit for the various complicated applications. The cache mechanism is better at dealing with the temporary data which need to be read and written frequently. But in deep packet processing, cache miss occurs when reading each segment of packet. We propose a cooperative mechanism of local memory and cache. In which the packet data and temporary data are stored into local memory and cache respectively. The analysis and experimental evaluation shows that the cooperative mechanism can improve the performance of network processors and reduce processing latency with little extra resources cost.
