Novel Long-Term Information Based Language Identification
Authors: Xu Jia Xin , Wei Yan , Qiu Feng , Sun Bo
Published: March 2013

A novel long-term information feature for language identification called shifted cepstra curve (SCC) is presented in this paper. Long-term information consists of information over multiple frames, which are commonly used in language identification systems. For instance, in parallel phone recognition language model (PPRLM), the feature vector contains not only information surpassing multiple frames but also linguistic knowledge [1]. However high computational cost for modeling linguistic gram may preclude their use in tasks which demand low memory. By contrast, experiments have proved that linguistics independent long-term information can also achieve high performance in language identification with much lower computing cost. For instance, Shifted delta cepstra (SDC) is employed as long-term information features to establish GMM based language identification systems, which can achieve comparative or even superior performance to PPRLM [2-4]. While, though SDC feature could model the dynamical information across multiple frames, the approximation is not precise enough for language identification. Thus, this paper further presents a new method for linguistics independent long-term information extraction by curve fitting algorithm. Experiments show that new feature based language identification systems are superior to not only short-term features based but also SDC features based systems.

This is the brand-new century, which is a new information technology, international and comprehensive era. The pressure of looking for work is very big, thus the competition is very intense. At the same time, many high comprehensive quality talents are needed. While our strong specialized colleges and universities need more students, whose professional knowledge and knowledge of foreign language are excellent. They can stand out in job markets where there are few opportunities for employment. There are some problems in specialized foreign language development of colleges and universities, and puts forward some relevant countermeasures based on analyzing these problems.

Three-Dimensional Unsteady Simulation in a Water Turbine
Authors: Hu Ying , Wang Kun
Published: March 2013

This paper introduces the 3D numerical simulation of unsteady turbulent flow in the entire flow passage of a water turbine model with CFD technology. A new and available method for the design of a Francis turbine has been explored. The boundary conditions have been implemented based on the 3D averaged N-S equations. The governing equations are discreted on space by the finite volume method and on time step by the finite difference method. The 3D unsteady turbulent flow in an entire Francis turbine model is calculated successfully using the CFX-TASCflow software and RNG k-εturbulence model. Transient flow fields are simulated in the spiral case, the distributor, the runner and the draft tube. It is presented in this paper that the computer simulation of the flow fields in components of the Francis turbine at the optimum operating condition. Meanwhile, the velocity and pressure at any points in the flow fields can be obtained so as to provide the great value on the performance prediction. According to the simulating results, the flow analysis and the design experience, the design of components in a Francis turbine model can be improved and optimized. In this way, designers may decrease numbers of test and shorten the period for a model. Therefore, the cost of research and produce can be reduced.
Safety Rules and its Technical Implementation of Campus Network
Authors: Qin Li Bo
Published: March 2013

Campus network security has become a growing challenge. All universities are beginning to look at these issues to improve the protection of information technology structure due to the increase of viruses, spam, hackers, and identity theft. Also, universities have the highest vulnerability to network security threats. So the campus network will face greater risks, whether campus network is truly safe or not, have an important sense for the entire campus normal work. It is believable that the network security model in the paper will play a very good reference for other networks to build a security system.

A Hybrid PSO Algorithm for Vehicle Routing Problem with Simultaneous Delivery and Pickup
Authors: Wang Sun Xin , Li Yan , Zhang Yan Rong
Published: March 2013

In this paper a hybrid algorithm named IPSO-VND is proposed and applied to solving the vehicle routing problem with simultaneous pickup and delivery (VRPSPD). The IPSO-VND algorithm combines two meta-heuristics: Improved Particle Swarm Optimization (IPSO) is used to find a group of excellent solutions, and then the Variable Neighborhood Descent (VND) is implemented to deeply search to achieve the optimal solution around these solutions. During the IPSO procedure, in order to make up for the change of a particle’s position, a velocity component is added to the movement of any particle which has been optimized or made feasible. During the VND procedure, three different neighborhood structures: insertion, swap and cross are successively used. Computational results on the benchmark problems show that our IPSO-VND algorithm is effective.
