For enhancing predictive discovery of hidden ore deposits in such mature environment, the key strategies which should be adopted include the innovation of the exploration models, application of the advanced exploration techniques and integration of multiple sets of information. The innovation of the exploration models should incorporate the new metallogenic concepts that are based on the geodynamic anatomization. The advanced techniques applied in the mature exploration environment should aim at the speciality and complexity of the geological setting and working environments. The information synthesis is to integrate multiple sets of data for giving a more credible and visual prospectivity map by using the geographic imformation system(GIS) and several mathematical methods, such as weight of evidence and fuzzy logic, which can extract useful information from every set of data as much as possible. Guided by these strategies, a predictive exploration in Fenghuangshan ore field of Tongling copper district was implemented, and a hidden ore deposit was discovered.展开更多

A new enterprise coming from merger is different from the one that come into existence. The strategy of new enterprise formed from merger is constituted through the integration of the strategy for each side. Strategy integration is the guide for the integration of other elements after merger, the way for enterprises to adapt the change of environment and the warranty for the enterprises to achieve strategy synergistic effect. Strategy integration of the merging-enterprises can be realized through several steps: preparation for strategy integration, readjustment to strategy, reorientation of the enterprise and effective communication with target enterprise in the course of carrying out the strategy.展开更多

During this optimization process, the weights are varying with the increasing generation instead of fixed values. The proposed strategy together with the linear matrix inequality (LMI) or the Riccati controller design method can find a series of uniformly distributed nondominated solutions in a single run. Therefore, this method can greatly reduce the computation intensity of the integrated optimization problem compared with the weight-based single objective genetic algorithm. Active automotive suspension is adopted as an example to illustrate the effectiveness of the proposed method.展开更多

文摘Under the dual influence of the rise of global trade protectionism brought about by the trade frictions between China and the United States and COVID-19,foreign trade has been greatly impacted.The integration of culture and tourism is an important path to play the role of domestic consumer market in pulling the economy and to improve the quality of people’s lives.In the study,four paths of culture and tourism integration were proposed,including the integration of concepts and functions,integration of industry and market,integration of services and marketing,and cross-theoretical integration of culture and tourism.
文摘At present,there are some problems in rural areas,such as the gradual decline of social trust,the dislocation of social norms and the disembeding of social network.As a result,the scale effect of characteristic agricultural industry is not obvious,the coordination of chain and network is low,and the willingness of farmers to participate is not strong.This article thinks that against the backdrop of the strategy of rural revitalization,we can explore the integration and development path of China's characteristic agricultural industry from three dimensions:social capital integration,chain-network synergy integration and brand value-driven integration.This paper analyzes how social capital is embedded in China's characteristic agricultural industry and form its own unique industrial brand,to give full play to the influence of brand value,and then drive the surrounding industries to form a highly integrated and symbiotic chain-network relationship,in order to improve the internal driving force of the characteristic agricultural industry.
文摘Merger is a kind of strategic behavior of seeking long-term development. A new enterprise coming from merger is different from the one that come into existence. The strategy of new enterprise formed from merger is constituted through the integration of the strategy for each side. Strategy integration is the guide for the integration of other elements after merger, the way for enterprises to adapt the change of environment and the warranty for the enterprises to achieve strategy synergistic effect. Strategy integration of the merging-enterprises can be realized through several steps: preparation for strategy integration, readjustment to strategy, reorientation of the enterprise and effective communication with target enterprise in the course of carrying out the strategy.
文摘The evolutionary strategy with a dynamic weighting schedule is proposed to find all the compromised solutions of the multi-objective integrated structure and control optimization problem, where the optimal system performance and control cost are defined by H2 or H∞ norms. During this optimization process, the weights are varying with the increasing generation instead of fixed values. The proposed strategy together with the linear matrix inequality (LMI) or the Riccati controller design method can find a series of uniformly distributed nondominated solutions in a single run. Therefore, this method can greatly reduce the computation intensity of the integrated optimization problem compared with the weight-based single objective genetic algorithm. Active automotive suspension is adopted as an example to illustrate the effectiveness of the proposed method.
