At the regional level the School of Training provides Guangdong Province with its Highly Skilled Professionals Training Base. And at the local level, the school provides the Municipality of Shenzhen with its Highly Skilled Professionals Training Base and its Reemployment Training Base for the Unemployed.In total, the School of Training offers more than 290 vocational skill training and vocational qualification certification training programs. It is authorized to test more than 100 different types of work at technician, primary, intermediate, and advanced levels as well as vocational skills.The polytechnic has six programs of natural science research registered and funded at the national level, and in the Tenth Five Year Plan is ranked 15th for research amongst colleges in Guangdong Province. In recent years, it has published 2200 academic papers on natural science, more than 3400 papers on social science and 400 textbooks on higher vocational and technical education. The polytechnic was ranked first among China ’s vocational colleges in 2004 and 2005.The polytechnic has cooperative relationships with 40 universities and educational organizations outside of mainland China. These include universities and academic institutes in Britain, Germany, France, Australia, the United States, Japan, South Korea, Hong Kong and Taiwan . Seven foreign languages, including English, French, German, Japanese, Korean, Russian and Spanish, are taught on campus. And since 1998, for purposes of educational and cultural exchange and cooperation, it has received 30,000 visitors from other universities and educational organizations at home and abroad.The polytechnic enjoys the attention and support of leaders, not only of Guangdong Province and Shenzhen Municipal Government, but also of the Chinese central government. On September 12, 2005, Premier Wen Jiabao paid a visit. In 1997 and 1998, the former Vice Premier Li Lanqing toured the campus, and left written words of encouragement and appreciation. Other leaders visiting campus have included Ms Chen Zhili, Member of the State Committee, Zhang Dejiang, Secretary of Guangdong Province CPC, and Zhou Ji, Minister of the Ministry of Education.

The most famous one for finding the shortest path is the Dijkstra, but it has some limitations. For example, when there are more than one shortest path between the source node and one special node, Dijkstra could find only one of them. Besides, the algorithm is quite complex. This article introduce a conception of coding graph, abstracting the problem of shortest paths and critical paths into the same mathematical model to describe and solve, presents a new algorithm of finding the paths. The algorithm extends first the data structure of the orthogonal list, so that the graph will be stored in the same storage space with the path searching process and result data. Codes for all nodes in the graph starting from the source node, using the rule of getting extremum in the weighing calculation and breadthfirst, When accessing recursively the adjacent nodes from the current node, re-estimate the distance of neighboring node and entering edge list. if the distance of current node plus the weight of the edge to the neighboring node is less then (or greater than) the original distance of the neighboring node, then set this value as the new distance of this neighbor node, if the distance of current node plus the weight of the edge to the neighboring node is greater than (or less than) the original distance of the neighboring node, then the edge node will be deleted from the entering edge list, until all the nodes were coded and the coding graph of shortest path (or critical path) is created. For each node in the coding graph, starts searching from entry edge list recursively could get all shortest paths (or critical paths) and distances to the source node. Compared with the existing algorithms, this algorithm is simpler and more understandable, needs only 3n+5e storage unit that is much less then that of Dijkstra (which is n 2+2n). The time complexity O(n+e), which is also lower than the Dijkstra O(n 2). © 2012 ACADEMY PUBLISHER. Source

In this paper, an efficient resource management system in wideband code-division multiple access (WCDMA) cellular communications with quality of service (QoS) has been investigated. Resource requirements are considered separately for the uplink and downlink. The proposed scheme is to design a simple admission control algorism that ensures adequate signal-to-interference ratios for both the incoming call, as well as previously admitted calls. Properly power allocation and coordination soft handoff schemes are considered in the summarized resource management. The performance of the proposed algorithms is explored through simulations for three types of traffic, namely voice, video, and data to meet the respective QoS. System capacities with the proposed algorithms are further investigated to indicate achieving high spectrum utilization with low probability of overload. © 2011 by Binary Information Press. Source

In order to meet increasingly stringent automotive exhaust emissions regulations, alternative fuels such as LPG have been applied in automotive engine. This research has developed fuel control system for a spark-ignition LPG engine. Neural networks proportional integral control algorithm is used in this system because neural networks own many advantages such as parallelism, self-organization, memorization and fault-tolerance. The combination of neural networks and PI method can improve control precision of air fuel ratio. The mapping method is introduced in the EGR control system. This method is simple and reliable. It is suitable for real-time control. The software and hardware designs of control system are also described in this paper. Neural networks PI AFR control, EGR control and the performance optimization have been developed in a 1.46-liter 4-cylinde spark-ignition LPG engine. The experimental results show that this system can achieve satisfactory control effect. © Sila Science. All Rights Reserved. Source

With the rapid development of the network, network bandwidth has been greatly improved. In high-speed network environment, higher requirement is needed to the intrusion detection system (IDS). The packet capture capability of IDS has become the bottleneck to enhance the system performance. At present most IDS apply LINPAC to capture packet. This paper analyzes and designees an packet capture module in IDS based on Snort, and then shows the design structure and work process. © Springer-Verlag Berlin Heidelberg 2014. Source

The effects of particle-size distribution on a granular assemblage's mechanical response were studied through a series of numerical triaxial tests using the three-dimensional (3D) discrete-element method. An assemblage was formed by spherical particles of various sizes. A simple linear contact model was adopted with the crucial consideration of varying contact stiffness with particle diameter. Numerical triaxial tests were mimicked by imposing axial compression under constant lateral pressure and constant volume condition, respectively. It was found that an assemblage with a wider particle grading gives more contractive response and behaves toward strain hardening upon shearing. Its critical state locates at a lower position in a void ratio versus mean normal stress plot. Nevertheless, no obvious difference in the critical stress ratio was shown. Model constants in a simple but efficient phenomenologically based granular material model within the framework of critical-state soil mechanics were calibrated from the numerical test results. Results show that some model constants exhibit linear variation with the coefficient of uniformity whereas others are almost independent of particle grading. This investigation provides an opportunity to better understand the implications and meanings of model constants in a phenomenologically based model from the microscale perspective. © 2011 American Society of Civil Engineers.
