Authors: Chen Ming Qiang
Published: July 2013

Air traffic is increasing worldwide at a steady annual rate, and airport congestion is already a major issue for air traffic controllers. The traditional method of traffic flow prediction is difficult to adapt to complex air traffic conditions. Due to its self-learning, self-organizing, self-adaptive and anti-jamming capability, the hybrid fuzzy neural network can predict more effectively the air traffic flow than the traditional methods can. A good method for training is an important problem in the prediction of air traffic flow with neural network. This paper will try to find a new model to solve the traffic flow prediction problem by hybrid fuzzy neural network.

Authors: Yang Yi Yong , Ren Xiao Jing , Li Si Chen , Zhu Li Min , Tian Shang Yun
Published: July 2013

A new hydrocyclone and gas-flotation device was designed and tested for the treatment of the wash water containing the flocs. The device separates particles and removes flocs simultaneously. The gas-generator equipment can produce a large number of micro-bubbles, and the bubbles adhere to the impure flocs particles. This makes the density of the bubble-floc less than that of water, and their buoyancy enables particle separation and removal of suspended flocs. To achieve a high efficiency of flocs removal and particle separation, some of the factors that influence the separation efficiency (such as the gas-liquid pressure difference, gas-liquid ratio, underflow split ratio, water pressure, inlet flow rate, and the contact time of the gas and particles, bubble size, and number of bubbles) were investigated. The results showed that there is an optimum combination of multi-dimensional parameters; good particle separation and a high efficiency of flocs removal were achieved.

Authors: Wang Zuo Hua , Zhang Jia Hui , Zong Hua , Wang Wei , Fang Hong Bo
Published: July 2013

Hydrolyzed polyacrylamide (HPAM) has been widely used for enhanced oil recovery in oil production. However, metal ions existed may reduce the system viscosity and further impact the displacement efficiency. Thus, it is of importance to know the mechanism between HPAM and metal ions. UV spectrophotometry method can be effectively applied in this work. It is suggested that the extent of various metal ions on HPAM viscosity is in the order of Fe2+ >Ca2+>Na+. By shielding effect, the presence of large amount of Na+ reduces HPAM solution viscosity. The result also demonstrates that multivalent cations can form polyion-metal complexes which affect the solution viscosity. The viscosity degraded by Fe2+ is attributed to its reducing action. With oxygen in sewage, Fe2+ initiates a free radical reaction and causes the disintegration of the polymer.

The platform of rural distance learning (PRDL) is an interactive tool used to farmers for the video training, interactive consulting, teaching and management with the features of resource integration, safe, and reliable. PRDL was dual-network transmission structure via the Internet and E-government network, covering all the Beijings towns and villages, which is applied media asset management technology to build a municipal teaching resource library. The problems of PRDL are solved such as complex network for rural areas, limited bandwidth resources and diverse user needs base on in-depth study of distance learning key technologies. It is for farmers learning modern agricultural technology to provide a strong support.

Published: July 2013

Games have been shown to be highly effective in education. Consequently, game-based learning is attracting more attention from researchers. However, the existing game-based learning systems lack the effective learning method required to provide a proper review strategy for the enhancement of learning. This paper proposes a game-based learning system using the graduated-interval recall method to organize game contents and learning courses with appropriate review intervals according to learning status. The evaluations were conducted on the proposed system at Gwacheon National Science Museum in Korea with children visitors. The validity of the proposed system was verified by an analysis of the experimental data.

In view of the present situation of harmonic management at present, put forward the harmonic pollution emissions trading and harmonic insurance contract mechanism of the two methods to manage. We first introduce the basic idea of harmonic pollution emissions trading, the general steps and market supervision. Through emissions trading to the regional total funds management and harmonic environment capacity can achieve optimal allocation. Secondly, introduces the mechanism of harmonic insurance contract, by using the method of electric harmonic insurance contract signed between the two sides of the harmonics management. By concluding an insurance contract will users due to harmonic problem and the loss of risk transfer to the electric power company, the loss of the user can obtain a reasonable compensation. Implementation of the harmonic pollution emissions trading and harmonic insurance contract management method, could make the power network and the user to achieve profit optimization and take the initiative to improve power quality, but also promoted the development and technology of harmonic method.

Published: July 2013

This paper studies the connotation and features of green manufacturing-oriented machining process planning and the methods to optimize it. It argues that, through optimized decision making and planning concerning process routes, process methods, process equipments, process parameters, process programs and so forth, each phase of the technological procedure can be improved to be more environmental friendly. Hence both economic and social benefits will be coordinated and optimized during product production. Fewer resources will be consumed and the negative influence on the environment will be mitigated.

Published: July 2013

According to the shortcomings such as long cycle, large consumption in view of the traditional method of shipbuilding, introduce the method named collaborative design, build hull production design process model. First, decompose hull production design process, then introduce the method of DSM-matrix to describe hull production design task, build the hull production design process model, then based on the model, develop collaborative design system. And use the system to make the hull production design process more reasonable. At last successfully apply them to the collaborative design system. The results suggest that the hull production design method based on DSM-matrix can effectively shorten the manufacturing cycle and save material.

Cultural diversity and language variants resulting from the fast development of information technology influence the college English teaching including its methods and contents. Based on this background, we have discussed the understanding of multimodality and multiliteracies in the first part. Then through the research about college students’ awareness and level of multiliteracies, we can conclude that college students’ weak performance in multiliteracies. Therefore, some methods are suggested to improve college students’ multiliteracies and at last the instructions that the concept of multiliteracies has brought about for college English teaching are discussed.
