Economic Analysis on Concrete-Filled Steel Tube Structure
Authors: Liu Jin Ming
Published: September 2013

The concrete-filled steel tube structure possesses the advantages stemming from both steel and concrete. When the structure receives pressure, the concrete in the steel tube bears the stresses from three directions owing to the restriction of the steel tube. The structure does not only have high bearing capacity but also a good plastic property. Though the wall of the steel tube is thin, the local deformation of yielding can be prevented due to the presence of concrete in the tube. The combination of both materials can help conquer their respective weakness and bring their strong points into full play.Therefore the concrete-filled steel tube structure has a bright future. Whether a structure system has a bright future largely depends on the economic benefit of the system. This paper presents an economic analysis on concrete-filled steel tube structure by way of comparing the reinforced concrete structure.
Numerical Analysis on the Influence of Joints Inclination on the Characteristics of Deformation and Stability of Tunnel
Authors: Tang Xiao Song , Wang Yong Fu , Zheng Ying Ren
Published: September 2013

The paper adopts the interface element to simulate the joints so as to systematically and quantitatively study the deformation around tunnel, the mechanic state of lining and the stability under different inclining angles of joints. The result shows that the deformation around tunnel deteriorates mainly along the joint during the inner convergence effects of surrounding rock. When the inclining angle α=45°, the deformation around the tunnel is most serious, followed by that when α=90°, α=60°, α=30° and α=0°. At the same time, the influence of inclining angle on the distribution of the axial force of lining is comparatively small. But the distribution of bending moment and shear change obviously where the joints penetrate the tunnel. The tunnel stability of surrounding rock is the poorest when α=90° and the tunnel is most stable when α=0°. The stability of surrounding rock changes little when α is between 30° and 60°. The research result provides an effective calculation method for the forecast of deformation, the design of structure and the stability analysis of jointed tunnel. It is also helpful for the monitoring of construction and calculation of jointed tunnel in the future.

Authors: Zhao Si Yuan , Tao Wang , Xin Ge , Liu Yun
Published: September 2013

A novel bearing fault diagnosis method based on Lie group was proposed, and genetic algorithm (GA) was introduced to optimize feature amount. This method was applied to inner ring fault, outer ring fault and rolling element fault of rolling bearing. Firstly, the rolling bearing vibration signal was decomposed as intrinsic model functions (IMF) by using the empirical mode decomposition (EMD) method. The energy of every IMF and the singular value of the IMF matrix were chosen as features. The Shannon and Renyi entropy of the energy and singular value distribution were also extracted. Secondly genetic algorithm was used to reduce feature redundancy, with lowest classifier error rate and least feature amount as finess function. At last, a comparison was made between this method and least square support vector machine (LSSVM).The results showed that Lie group clkassifier was more sensitivce to feature. This method could use less feature amount to diagnose fault.

A Study on Incentive Mechanism for Star Hotel Employees against the Background of IT Application
Authors: Li Dai Hong
Published: September 2013

This paper conducts a study on some problems on the reform of incentive system for star hotel employees against the background of IT application. It emphasizes the importance of incentive mechanism for star hotel employees against the background through empirical analysis and discusses how to provide incentives to employees of star hotels so as to strengthen their awareness and quality and initiatively integrate themselves into the hotel. Moreover, this paper tries to find out an incentive mechanism fit for employees of star hotels to provide a reference for senior management of star hotels.With the advent of knowledge-based economy and the acceleration of global integration, competition between hotels are, more often than not, manifested by competitions in managerial talents. As salary system plays a decisive role in attracting and retaining talents, stimulating people’s innovative ability, and raising core competitiveness and securing sustainable development, a scientific and rational salary system has already become an important strategic prerequisite for successful corporate management. Therefore, seeking and building up a modern salary system to foster an effective incentive and restraining mechanism is not only a core issue in theories on modern business management, but also has become an urgent task of vital importance in the deepening reform of state-owned enterprises. However, currently, the lack of an effective salary management system has resulted in the sharp decline in salary attraction. As a matter of fact, though a great number of senior hotel managerial staff has realized the salary administration’s importance to the development of hotels, most of them fail to find out a feasible strategy in this aspect. As a result, they fail to uphold the tenet of “people first” for the benefit of employees. In other words, their degree of cognition over the importance of salary administration is not downright enough, not do they have a right cognizant idea for the proper place of salary administration. In recent years, there have been a serious drain and the high mobility ratio of employees, which have become a big headache that persecutes hotel managerial staff. In this sense, how to build up an objective and rational salary administration system to raise employees’ master consciousness and quality and for them to integrate themselves into the hotel has become a challenge in china’s hotel industry which demands prompt solutions.

Application of Nanoscale Zero Valent Iron Combined with Impatiens Balsamina to Remediation of E-Waste Contaminated Soils
Authors: Gao Yuan Yuan , Zhou Qi Xing
Published: September 2013

E-waste contamination is of major environmental concern on a world scale, with the rapid development of electric industry. The recycling and disposal methods of e-wastes remain rudimentary, and pose a serious environmental threat and have adverse influences on human health, because toxic pollutants such as polychlorinated biphenyls (PCBs), and heavy metals are released into the environment during crude recycling. nanophytoremediation is a combined technology between nanotechnology and phytotechnology for remediation of contaminated environments. This work was aimed to investigate the tolerance and accumulation characteristics of e-waste pollution, as well as the effect of nanoscale zero valent iron (nZVI) on their phytoremediation capacity. Results showed that nZVI could facilitate the growth of plants both under clean soil and the high pollution, with increased by 30.3% and 53.5% respectively. This may be attributed to the improvement of soil quality and adjustment of soil pH by nZVI. Especially, all the nZVI adding treatments had significantly higher PCBs accumulation efficiency compared with that without addition of nZVI, thus indicating nZVI-phytroremediation would be a very promising method in the future.
