Cloud computing is the future trend for enterprise software solutions, which means a lot of legacy systems will need to be either adapted to fit the requirement of cloud computing or to be purged and redesigned from scratch. However, enterprise software is far too complex for any human being to understand as a whole. This paper proposes a novel approach to reengineering enterprise software for cloud...
Capability Maturity Model(CMM) was introduced into the theory of subprime crisis and export trade in this paper to analyze the impact of subprime crisis on the export of the textile industry of Nantong area, China. It was proved that CMM model could be applied in other industries except software organization in this paper. The analysis idea of CMM model showed great guiding significance, especially...
Regional financial development and economic growth are closely related. The financial volume growth is important, but if not coordinated with the structure of financial assets, financial development will not be sustained, and thus also affect the long-term economic growth. This paper, starting from a regional financial asset structure, combined with Harrod-Domar model and the Tobin model of monetary...
In connection with the uncertainty problem of pollutants diffusing in the atmosphere of Wuan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to...
The concept and category was discussed in this paper, which introduces the present situation and several basic questions and studied methods of environmental information technology, centers on several kinds of environmental information technology, and prospects for the developmental trend of it. It is important to solve environmental problems, prevent environmental pollution, benefit human beings.
Generally, hydroelectric projects have long construction period, and its investment scale is very big. Simultaneously, its construction technology is difficult. Under these conditions, how to balance construction cost, schedule, and quality is always a problem concerned by constructors. In construction management, the optimum goal is minimum cost with the guarantee for schedule and quality. This paper...
It is well known that construction project management involves such objectives as duration, cost, quality, resource leveling and so on. It is necessary to integrate and balance multiple objectives in management process. So this paper firstly analyzes single-objective optimization models such as duration-cost model, duration-quality model and resource leveling model and the relationship between duration,...
Chinese word segmentation is an important foundation for Chinese information processing. This paper proposes a new Chinese word segmentation model based on Bayesian network. In this model, Character alignment Viterbi algorithm, which treats the preceding word of each Chinese character as its state, and the N-gram probability as its state transition probability, is suggested to be combined with Viterbi...
Some nonlinear physiological bio-signals like electroencephalograph (EEG) are not intuitive for analysis. Some mathematic model should be used to process the EEG data first. In this paper, theories and methodology of fractal dimension were introduced first. The enhanced dynamic fractal dimension model (DFDM) with sliding window was developed to analyze the nonlinear physiological bio-signals allowing...
It usually takes long time to simulate rare event using traditional Monte Carlo method, while importance sampling techniques can effectively reduce the simulation time and improve simulation efficiency. A new implementation for importance sampling method to estimate rare event probability in simulation models is proposed. The optimal importance sampling distributions was obtained by making use of...
