Authors: Liang Di , Tang Sheng Jing
Published: March 2014

Aerodynamic analysis and calculation are very important parts in the aircraft design, and aerodynamic engineering prediction is widely used in the aircraft preliminary design stage. However, traditional aerodynamic engineering prediction causes heavy computation and is time-consuming. The developed software such as DATCOM has the disadvantages of complicated operation and black box structure. To overcome the disadvantages above, we develop the software for aerodynamic engineering prediction based on the aerodynamic characteristics and prediction for aircrafts. There are three parts in this software which are database, calculation module and user interface. The software is verified by a numerical example of one aircraft, and compares with the data of Computational Fluid Dynamics (CFD) and the wind tunnel test. The results show that the calculated results of the aerodynamic engineering prediction and CFD are basically consistent, and the software is able to meet the accuracy demand in the preliminary design phase of the aircraft.

A Hybrid Transmitting Algorithm for Unequal Cluster-Based Routing Wireless Sensor Networks
Authors: Bai Xu , Wang Chang Hong , Zhang Jia Yan
Published: March 2014

A cluster-based network topology enables the efficient utilization of the limited energy resources in network; based on multi-hop clustering model, the unequal routing protocol can lead to uniform energy dissipation among the cluster head and achieves some improvement on the network lifetime. However, the bottleneck zone, where the energy of the nodes closer to the Sink is depleted quickly, still limits the network lifetime in some cases; especially the collecting data cant be compressed. In this paper, a Hybrid transmitting protocol for Unequal Cluster-based Routing WSN(H-UCR) was proposed, which combined single-hop and multi-hop transmission is implemented to balance the energy dissipation among the entire network. Simulation results demonstrate that our proposed approach is effective in balancing the energy consumption and prolonging the network lifetime.

Authors: Zhang Da Jian , Lu Min Yan , Zhao Xing Yu
Published: March 2014

As computer-based systems play an important role in our daily life, dependability assessment of these systems is of great significance. Simply combining the result of each dependability attribute could not reflect system dependability faithfully. Therefore, holistic methods to assess dependability are necessary. As a new and promising method which focused on demonstrating the dependability of product-specific system, structured assurance case model receives growing attention. Build a dependability case systematically and effectively is challenging work, particularly for systems which involves multi-contractor who have different responsibilities. In this paper, we proposed a new dependability case construction method to address the ownership problem of system dependability case which involves multiple contractors. Our method extends the existing Dependability Deviation Analysis with contractors analysis and elicitation and integrates the contractors information into the whole dependability argument architecture. We illustrate our contributions by application to a Train Control and Monitor System which preliminarily shows the effectiveness of our method.

First-Principles Investigation of Electronic Structure and Dynamic Properties of SrCl2 under High Pressure
Authors: Hao Ai Min
Published: March 2014

We present an investigation of electronic structure and dynamic properties of SrCl2 under high pressure using density functional theory (DFT). The calculated electronic structures show that SrCl2 is an insulator with a band gap of 5.22 eV at ambient conditions. The band gap initially increases with pressure, then decreases upon further compression leading to band overlap metallization. The pressure of metallization is predicted to be 102 GPa. The calculated phonon curves indicates that the sequence of the pressure-induced structural transition of SrCl2 is from fluorite structure (Fm3m) to orthorhombic structure (Pnma), then to hexagonal structure (P63/mmc).

In order to obtain the anticipated sand/dust concentration and uniformity in the test segment, numerical simulation methods are adopted to study the characters of different sand/dust inject approaches. Research results indicated that the gravity sand/dust inject approach is not suitable for the large sand/dust test system, upstream spray approach is appropriate to be adopted in dust test, the uniformity of upstream sand spray method is better than downstream sand spray approach, but its diffusivity is not as good as the latter. In a certain range, the velocity difference between sand/dust spray flow and air flow affects the concentration distribution uniformity slightly. The numerical simulation results applied in the optimal design of particles inject system in some large sand/dust test system get a favorable progress. All results provide reference for the design of similar system and sand/dust environment test.

To responses to the current information "overload" problem widespread in e-commerce systems, a new approach, using the method of user clustering, node trust value analyzing and product evaluating is put forward to build an e-commerce trust community for e-commerce recommendation. According to some of the most trusted neighbors` evaluation information for goods, the recommendation model predicts the score of goods that the users have purchased, to recommend items which have a higher value score, to a customer. In the proposed recommending algorithm, the time effect of recommendation is taken into consideration to provide effective recommending services for users.
Research on Music Teachers' Professional Quality Evaluation Based on AHP
Authors: Lv Xin Xin
Published: March 2014

The purpose of the teachers' quality evaluation is to promote the professional development of teachers to improve the effectiveness of teaching. It is essential for the growth of teachers and the development education to scientific evaluate the teachers quality. This paper uses analytic hierarchy process to study the basic work of college music teachers quality evaluation and then calculates indication weights after established an evaluation indication system structure model. We should improve AHP, because the traditional AHP method is difficult to pass consistency test for judgment matrix, then we can use the optimal transfer matrix that can meet compliance requirements naturally to directly obtain weights. Calculation results of weights show that if we want to improve the professional quality of music teachers, we must focus on the basic knowledge of music, the basic literacy of music, the ability to orchestrate music, the ability to appreciate music and other aspects.
