Abstract: With the development of digital campus network users, web users exhibit scale up, the campus network users to use different computer level each are not identical, uneven, a potential threat to network is more serious, campus network security has become an urgent need to solve the problem. In this paper, based on the neural network, the concept of Elman memory, and proposed an improved algorithm of Elman neural network, the realization of network intrusion detection. The experimental results show that, the algorithm can effectively improve the accuracy of network intrusion detection algorithm.

Abstract: The process CAD design is the key part for steel casting production in general foundry enterprises. Formerly, for those parts with PDF file from customers, especially foreign customers, the process CAD design was done just by 2D casting process CAD system depending on AutoCAD system; so the designer must spend much time drawing part by AutoCAD according the PDF file which cause low efficiency. In this paper, a new process CAD design method is proposed based on PDF file in order to avoid drawing part by AutoCAD. Fist, the framework of process CAD design is constructed. Second, as the base part of process CAD design, the practical 2D CAD frame is established. Third, the part drawing with PDF file is resolved to be displayed clearly through the Mupdf rendering engine. Finally, the casting processes design of two actual steel castings, including a pump cover casting and a large gear casting, are presented to illustrate this new process CAD design method.

Abstract: Warfare simulation scenarios will play a vital role in helping commanders to make decisions, nowadays. However, one warfare simulation scenario usually includes lots of various information with complicated relations and is not so easy to form. Thus, this paper focuses on the presentation of a basic framework of the storage of warfare simulation scenarios, and also the improvement of management capability of them based on the methods of ontology and CBR. Through researching the process of joint air defense warfare, the paper constructed the warfare scenario ontology in that domain based on the method of first-order logic and, in the following, has given the proof of its consistency and completeness. Meanwhile, the paper has also illustrated one case using one feature set and carry out case retrieval based on this expression, which has improved the effectiveness of scenario management.

Abstract: With the development of sports, sports e-government platform applications more widely. A number of schemes on how to e-government platform of sports to make decisions, to choose the most appropriate solution is always facing the problem for policy makers. This paper uses linear weighted comprehensive evaluation method for comprehensive evaluation of the program. First, based on the former research results, construct the evaluation index system and weight; Then, follow the steps for solving a mathematical model, including a single index evaluation, the first level indexes and the total target evaluation; Finally, based on a mathematical model three programs to evaluate e-government platform, to choose the optimal scheme. The results show that the research method has clear ideas, the calculation is simple, easy to operate, objective results and other characteristics.

Abstract: E-government is a new approach for technology management and governance, with the advantage of optimizing workflow, improving government efficiency and promoting openness and transparency of government operations and so on, which is helpful for establishing a service-oriented government. It is widely used in developed countries; however, the construction of domestic E-government faces some problems, such as, talent shortage, insufficient fund, unclear understanding and lacking of information sharing. In order to better promote the construction of E-government, we need to strengthen the awareness of information services, broaden the multi-channel investment, strengthen specialized personals’ training and focus on integration of information resources.

Abstract: In this paper, the background of cloud computing technology to study how to optimize cloud computing data center energy efficiency mechanisms. This paper analyzes the DVFS energy saving strategy, virtualization energy saving strategy, turn off / on energy saving strategies, such as the current mainstream strategy, comparing different energy saving strategies have not applied scenes.

Abstract: Thread level speculation has been proposed and researched to parallelize traditional sequential applications on homogeneous multi-core architecture. In this paper, a heterogeneous multi-core hardware simulation system is present, which provides with TLS execution mechanism. With a novel TLS programming model and a number of new speculative tuning techniques, benchmark Gzip is parallelized from-3% to 195% on a four-core processor, and the speedup of the test benchmarks are 30%, 43% and 156%, respectively with arbitrary, hotspot and insight speculation.

Abstract: Long-Reach Passive Optical Network (LR-PON) is widely acknowledged as a promising solution for communication system in smart grid. Survivability is one of the key issues in the planning of LR-PON because massive high-rate traffic flows may be interrupted in case of network component failure. However, the survivability issue of LR-PON is addressed in few works. Most of previous works focus on single distribution fiber failure and remain untouched the simultaneous failure of multiple distribution fibers. In this paper, we focus on the survivability of LR-PON against single Shared-Risk Link Group (SRLG) failure. A reliability model is proposed to represent the probability of reliable connection for each Optical Network Unit (ONU). Based on this reliability model, we propose a novel Backup Fibers Protection (BFP) approach, aiming at the optimization of joint allocating backup capacity and deploying backup fibers. Through extensive simulation, we investigate the performance of BFP and demonstrate its effectiveness in different scenarios.

Abstract: Wireless mesh network (WMN) is an up-to-date network emerging with the development of wireless communication technology. Nowadays, it has become more and more popular. Along with this development, its performance has been research focus. However, the problem is that there are less than a handful of tools available to provide IEEE 802.11s mesh nodes or mesh models, which hampers its progressive research. In this paper, we propose a generic model for modeling and simulating IEEE 802.11s in OPNET. A prototype is implemented. According to the analysis of the simulation results, the proposed simulation platform satisfies the workflow of IEEE 802.11s and implements basic functions of IEEE 802.11s, and hence is shown to be an effective tool to develop IEEE 802.11s.

Abstract: In the process of enterprise integration which carried on in the environment of could computing, we met the problems of multi-factor and the lack of systematic design. To solve the problems, the paper gives analyses on the enterprises integration requirements, and then puts forward the architecture of enterprise integration based on the SaaS platform. The paper designed the enterprise integration form the platform layer, the logic layer, the data layer, the exhibition layer and the business layer. And then focused on the technology of interface integration, data integration, service integration and business integration, the paper gives the design and realization of the key technology. In the practical application, we used the architecture on the design of the automobile supply platform which can realize the integration of the enterprises in the automobile supply chain, and improve the efficiency of the enterprise evidently.
