Based on financial management and enterprises of early-warning theory, this paper constructs a financial distress early-warning model using GA-SVM. First, it uses listed companies appearing in Shanghai Stock Exchange and Shenzhen Stock Exchange in 2007-2009 as sample books. Defining ST listed companies which have abnormity of finance status as signature of the listed company's financial crisis. Then it uses the data in the financial statements known to the public as the input feature vector and combine genetic algorithm and support vector machine. Use Taking an empirical research with the financial distress early-warning model. Test results of the demonstration study shows the model has a superiority in predicting financial distress.[...] Read more.
The study on the quality evaluation and the related technology on distant education can provide evidence for the quality teaching and learning, and ensure the high quality and efficiency for distant education. It is highly significant to construct the teaching resources and learning supporting system by establishing an appropriate system that fits the level of education and guarantees the teaching quality. On the basis of the research results of programs, standards and technology for the quality evaluation of the distant education, this essay puts forward a method of comprehensive quality evaluation by applying the theory of comprehensive evaluation into this area, which is a quantitative research about how to set and calculate the weight indices for the evaluation. This method can process the quality indices by quantity efficiently, give a direct view of the quality by the comparative analysis, and provide the evidence for improving the quality.[...] Read more.
A new color image quantization algorithm based on fuzzy kernel clustering is studied in this paper. Firstly, the original image is quantized to 256 colors using the octree algorithm. Secondly, based on the quantitative relation of the NBS distance and the color difference of human vision, the initial clustering centers and number are determined automatically. Thirdly, the clustering center color values are modified by use of the fuzzy kernel clustering algorithm in the Munsell space. And then, a color image quantization effect is achieved. At last, simulations are performed on the presented algorithm, and the simulation result shows that the presented algorithm not only can solve the problem of giving the number of quantization in advance but also has better quantization effect than the octree algorithm and fuzzy c-means algorithm in the same quantization number.[...] Read more.
The fixed communication interruption easily occurs in extreme disaster situation, so it needs a robust mobile Ad hoc wireless communication to deliver the rescue information with high quality and efficiency. But the widespread excessive energy consumptions loaded in mobile Ad hoc wireless routing network have become the restriction bottleneck of its application. Based on the routing protocol of AODV, this paper proposed a routing algorithm of AODVSE energy-saving protocol, and studied its effects of the working performance on mobile Ad hoc wireless network. The simulation results showed that the AODVSE protocol could be better to improve the energy-saving performance than AODV and DSR protocols by reducing the routing expiration time and the routing load and extending the network lifetime, in order to help to implement the accurate and immediate rescue.[...] Read more.
This paper aims at the deficiency analysis of computer network practical teaching in universities, focusing on the goals of teaching practice. On the practical teaching system, content and form etc, this paper uses practical teaching in all aspects of personnel training, and puts forward a set of integrated practical teaching program which is suitable for talents training.[...] Read more.
This paper sets out to explore the potential of “3S” (GIS, RS and GPS) technology in the area of historical geography studies in particular. During the later years of Tang dynasty the most of lands between Yellow River and Yangtze River suffered a chaotic juxtaposition of separatist regimes, i.e., FangZhen. By using relevant vector data, GPS data and remote sensing satellite imaginary on the appropriate platform of GIS, we improved the quality and accuracy of scientific studies of FangZhen Period much more than before. Tang FangZhen Information System, a focused custom GIS system, has also been developed here to explore the formation and development of FangZhen. GIS processes such as area, point and line representation and tracing, image/feature/script hotlinking and thematic representation are perfect to trace and display historical data across space.[...] Read more.
The purpose of this study was to provide a new reform thought of college mathematics teaching. Firstly, the advantages and disadvantages of traditional mathematical classroom teaching in class based on the information educational technology were analyzed in the paper. Secondly, the author proposed that course features, requests for teaching requirements, students’ statements and the cultivation of the abilities to analyze and solve problems should be considered when information educational technology was applied to mathematical classroom teaching and integrated with college education theories. Fundamentally, the quality of college mathematics teaching can be promoted steadily.[...] Read more.
Landscape pattern in mining area is both the result of long-term action of multi driving forces and the base of regional coordination and development. This paper takes Liyuan Town, where Jinggezhuang locates, in Tangshan as an example and analyzes land use changes in the year 1997 and 2003 using GIS. The results showed that in mining area in urban-rural fringe of plain area, the number and the fragmentation of the patches increased and the patch density as the whole was in a rising trend. And the patch number of each type of landscape distributed unevenly. The landscape pattern characteristics and evolvement in Liyuan Town indicates that under the double functions of mining development and urbanization, it is necessary adequately to obey the evolvement regularity of special landscape in region to promote the evolvement of landscape destruction, restoration, reconstruction and function, in order to realize the regional coordination development.[...] Read more.
The practical teaching is a very important component of higher education. It is a special platform which not only integrates abstract and concrete, but also integrates theory and practice. And it is the main channel to cultivate talents with innovative spirit and practical ability. Therefore, the reform of practice education is necessarily the most important work in the present teaching work. In order to achieve the anticipated results, universities should establish diversified mechanism of performance assessment on teacher, establish multi-type mechanism of cultivation on teacher and construct practical teaching teacher staff with reasonable structure.[...] Read more.
In the fierce market competition, technological innovation becomes a crucial element which effects the sustainable development of enterprises. That enterprises buy technology from the external could save limited resources, so more resources could be put into core business. The external purchase of innovative technology is essentially the results of the game between enterprise and innovative research institutions. The two players in the game analyze counterpart’s policy to choose the best strategy to achieve the greatest benefits.[...] Read more.
This paper presents a framework for remote virtual experiment implementation. The work principle of the solution is described and the three-tier structure of the system is proposed. The proposed solution is based on two commercially available software packages. MATLAB/SIMULINK is used for experiment module development, while .NET is used for the user front-end interface. The virtual experiment is divided into two kinds, static one and dynamitic one. The static remote virtual experiment is designed by MCR interface and the dynamitic one is done by MATLAB engine technique. In addition, two samples of remote virtual experiment are deployed to user.[...] Read more.
A three-dimensional, steady-state non-isotherm mathematical model for proton exchange membrane fuel cell is developed. The model takes into accounts simultaneously the mass, momentum, energy, species, charge conservation equation and combines electrochemistry reaction inside the cell. The simulation results show that it is easy to improve the fuel cell performance for higher porosity in the diffusion layer, because of the benefit of speeding the gas diffusion, reducing the concentration grads of gas, depressing the ridge board domino offect and falling current density grads.[...] Read more.
