Based on the statistical data during the period from 1978 to 2006 released by National Bureau of Statistics of China, this paper aims to apply the compensative GM (1, N) model and regression model to simulate the relationship between the expenditure for science & technology activities and economic growth in China. In the numerical experiment, the established grey model simulates the China's GDP values during the period from 2000 to 2006. The empirical research results reveal that the established mathematical model based on grey theory for the relationship between the expenditure for science & technology activities and economic growth has a higher precision than regression model. Research results show that this grey model established in this paper could provide valuable information to policy makers in their efforts to make technological and economic policies. © (2012) Trans Tech Publications, Switzerland.

In this paper, we proposed an effective genetic algorithm for solving the flexible job-shop scheduling problem (FJSP) to minimize makespan time. In the proposed algorithm, Global Selection (GS) and Local Selection (LS) are designed to generate high-quality initial population in the initialization stage. An improved chromosome representation is used to conveniently represent a solution of the FJSP, and different strategies for crossover and mutation operator are adopted. Various benchmark data taken from literature are tested. Computational results prove the proposed genetic algorithm effective and efficient for solving flexible job-shop scheduling problem. © 2010 Elsevier Ltd. All rights reserved.

This paper proposes a cellular particle swarm optimization (CPSO), hybridizing cellular automata (CA) and particle swarm optimization (PSO) for function optimization. In the proposed CPSO, a mechanism of CA is integrated in the velocity update to modify the trajectories of particles to avoid being trapped in the local optimum. With two different ways of integration of CA and PSO, two versions of CPSO, i.e. CPSO-inner and CPSO-outer, have been discussed. For the former, we devised three typical lattice structures of CA used as neighborhood, enabling particles to interact inside the swarm; and for the latter, a novel CA strategy based on "smart-cell" is designed, and particles employ the information from outside the swarm. Theoretical studies are made to analyze the convergence of CPSO, and numerical experiments are conducted to compare the proposed algorithm with different variants of PSO. According to the experimental results, the proposed method performs better than other variants of PSO on benchmark test functions. © 2011 Elsevier Inc. All rights reserved.

In 2013, Bai and Zhang (2013) constructed modulus-based synchronous multisplitting methods by an equivalent reformulation of the linear complementarity problems into a system of fixed-point equations and studied their convergence. In this paper, we generalize Bai and Zhang's methods and study modulus-based synchronous multisplitting multi-parameters methods for linear complementarity problems. Furthermore, the convergence results of our new method in this paper are weaker than those of Bai and Zhang's when the system matrix is an H+-matrix. © 2014 Elsevier Ltd. All rights reserved.

This research project inquired into students' perceptions of the effects of the Internet on their experiences of communication at college. The Internet is ubiquitous on college campuses and has the potential to both disrupt and enhance campus communication. Data for this study were collected from with eight hundreds full-time students, Qualitative analyses suggest that the Internet has both positive and negative effects on students' experiences of communication on campus. Students reported difficulty controlling the amount of time they spent online. The Internet was blamed for diminished face-to-face communications and message misinterpretations. The Internet was described as a positive way to meet people, develop relationships and maintain friendships. © 2011 Springer-Verlag Berlin Heidelberg.

Well-defined ZnSe nanowires were successfully synthesized on the composite layer of gold and carbon coated Si substrates by using a facile thermal vaporation method. These nanowires are of well crystalline cubic structure and the average length is up to tens of micrometers. It is found that the growth process follows a typical vapor-liquid-solid (VLS) mechanism, and the carbon layer can enhance the VLS growth process of the ZnSe nanowires. Moreover, the photoluminescence (PL) properties of the nanowires were investigated. Only a broad and strong red emission band centered at 629 nm is observed. The main reason is ascribed to the donor-acceptor pair recombination induced by a large amount of Zn vacancies and Zn interstitials existing in ZnSe nanowires. © 2009 Elsevier B.V.

Base on the successively engaging projection called teeth, gears are direct contact bodies, operating in pair, that transmit motion and force from one rotating shaft to another, it is one of the most important mechanical transmission forms in the field of mechanical engineering, it has various forms and uses widely, but the consequences caused by gear failure are often serious. Loaded contact performance, tooth contact stress and tooth root bending stress of the pair of gears are an important concerned index in the successive process of engagement. The precise modeling of involutes cylindrical gear is obtained by using the large scale CAD software, and using of the data interface of the finite element analysis software, it can import the model in the form of dxf into the finite element analysis software, the model of three dimensional finite element nonlinear contact was established. According to the geometric shape of the tooth, it can divide the model into lattice and impose the appropriate boundary conditions, it can be obtain the quasi static characteristics of the meshing tooth by using the finite element analysis. The results of numerical analysis showed that the model can accurately simulate the distribution of equivalent stress and the changing displacement in the process of tooth meshing gear, which verify the accuracy of the model, and the model can be used to deal with the dynamic meshing problem of gears.

The aircraft engine condition detection and fault diagnosis has become the core technology of the advanced engine manufacture, which has developed into a new science and technology. According to the statistics, more than 70% of the faults are shown as the form of vibration. So, the acquisition of the aircraft engine vibration signal can achieve the aircraft engine condition monitor and realize the fault diagnosis, which becomes a kind of effective method that can be implemented. In this paper, the pretreatment vibration data of the actual aircraft engine was analyzed in the amplitude domain, then a kind of natural gradient algorithm in self-adaptive step length was used to separate the vibration signal of the aircraft engine. At last, we analyzed the frequency spectrum energy of the blind separation signal. Through the experiment, we can accurately identify the aircraft engine work condition by the amplitude domain parameters, and judge the aircraft engine failure occurs times accurately, as well as estimate the aircraft engine fault type by using the blind signal separation algorithm that the paper proposing.

This paper studied the incentive mechanism of the processor and the manufacture with the Principal-Agent Theory. We analyzed the different design method of the incentive mechanism under the case of complete information and incomplete information. At the same time, we compared the two kinds of situation's similarities and differences of the incentive mechanism. Results showed that: in the case of incomplete information the manufacture can get the fixed income and take the risk. And in the case of complete information and incomplete information, the manufacture can get the same expected revenue which equals to the retained earnings. The retained earnings of the processor and the manufacture with the incomplete information are lower than that of the complete information.

Judging from current condition of college physical education in China, teaching methods exist more or less problems. To fundamentally improve the quality of PE teaching, a fresh approach is indicated to contact modern multi-media information technology with college sports cheek by jowl. The corresponding three method are Proposed in this article, namely, stress PE theoretical teaching, improve students' interest in studying PE by application of multi-media information technology, incorporate physical activity into students' extra-curricular life, with the hope of inspiring think and offering a new approach for college PE development. © 2013 Springer Science+Business Media.
