Aiming at prompting the performance in the process of designing of web-based data warehouse, the article examines the data on warehouse design, based on ETL Meta Data Model and Particle Swarm Optimisation (PSO). The Particle Swarm Optimisation Algorithm, which is presented for adjusting parameters for optimisation is compared with traditional algorithm to prove that it has better performance in error estimation. The experimental data show that the calculating speed, the control accuracy and the complexity can be significantly improved by using ETL Meta Data Model and Particle Swarm Optimisation in the design process of web data warehouse.

In order to promote rapid and steady growth of rural economy, China should apply the "Internet+" thinking to its agricultural development, and take innovative paths of agricultural modernization. Based on literature review and logic analysis, this paper analyzes problems existing in China's current agricultural modernization. These problems include lack of specialized Internet talents in the agriculture field, backward agricultural information technologies and standards and slow ecommerce development of agricultural products. Concerning these problems, four innovative paths to promote China's agricultural modernization via "Internet+" are proposed, including 1) improving "Internet+" policies and regulations in the agricultural field; 2) building the modern agricultural industrial chain; 3) building the agricultural industrialization system; and 4) improving the informationization level of agricultural enterprises. It is hoped that these innovative paths can contribute to building an agricultural modernization system in China at an earlier date.

With the rapid development of the times, tourism has begun to become one of the main pillar industries in the modern era. Under the trend of informationization, the new intelligent tourism model has begun to form and provide more opportunities and challenges for the development of the whole tourism industry. The concept and definition of the new type of intelligent tourism were analyzed, and the shortcomings of the new wisdom tourism were analyzed. The application of the intelligent tourism in all aspects of the industrial chain was summarized. The evaluation project in the intelligent tourism model was summarized, which provides certain theoretical support and scientific basis for the development of the whole tourism industry.

A large number of infeasible solutions often occur in population of evolutionary Computation (EC) solving the constraint combinatorial optimization problems. The greater the number of infeasible solutions in the population, the worse the performance of EC to search the solution, in the worst case, the algorithm ceases to run. The existing methods, penalty function or multi-objective optimization, can relieve partly the worst case of EC to run. However, they are actually to restrain the infeasible solutions surviving in population, the performance of the EC is not improved. In this study we propose an approach using an important feature of the infeasible solutions in Genetic Algorithms (GA). The approach can not only solve the problem of algorithm ceases to run, but also improve effectively the performance of genetic algorithms searching the optimal solution. From examination of the proposed method on multidimensional knapsack problems, the application of method is effective tosolve the problem of algorithm ceases to run as well as to improve clearly.

With the development of computer and information technology, the concept of corpus has changed greatly. The main form of corpus has evolved from the original written form of the text data to the current electronic text data, this functional system can realize the data retrieval, statistics, analysis and other kinds of applications. In this paper, the author put forward an improved method of English vocabulary teaching by using corpus and information retrieval. This paper discusses the principle of corpus assisted English teaching, and analyzes the innovation of thinking mode in English teaching. English corpus can provide a rich context to learners, which is conducive to the construction of learners' language knowledge. © 2017 Universidad Central de Venezuela.


Beginning with the increasingly serious situation facing human society, it describes the origin and meaning of ecological circular economy; after that, it focuses on the three main principles of the eco-circular economy, they are reduction, reuse and recycle principles. Then, it analyzes the eco-circular economy further from the angle of industrial technology and economic dimensions, summarizes the barriers to the development of eco-circular economy. Finally, the paper elaborates a number of measures in the establishment of eco-circular economy. © (2012) Trans Tech Publications.

In this paper, we study the following biharmonic equation Δ2u=K(|y|)up,u>0,inB1(0),u=Δu=0,on∂B1(0), where p=N+4N-4, K(1) > 0,K'(1) > 0, B1(0) is the unit ball in RN(N≥6). We show that the aforementioned problem has infinitely many peak solutions, whose energy can be made arbitrarily large. © 2016 John Wiley & Sons, Ltd.

Recycling of feedback renewable electricity of braking motors is an important approach to save energy. In this paper, the architecture of an energy storage system is analyzed to get the equivalent circuit firstly. Then, the switching system model is established for the bi-directional DC-DC converter of the energy storage system, and Lyapunov function is constructed to get the system switch rules. Simulation result shows that with the control of the switching rules, the model can fully absorb and utilize the feedback electrical energy of the motor, keep DC bus voltage steady, and save system energy.
