By combining the Back-Propagation (BP) neural network with conventional proportional Integral Derivative (PID) controller, a new temperature control strategy of the export steam in supercritical electric power plant is put forward. This scheme can effectively overcome the large time delay, inertia of the export steam and the influencee of object in varying operational parameters. Thus excellent control quality is obtaitud. The present paper describes the development and application of neural network based controller to control the temperature of the boiler's export steam. Through simulation in various situations, it validates that the control quality of this control system is apparently superior to the conventional PID control system. 展开更多

ATP-binding cassette exporters transport many substrates out of cellular membranes via alternating between inward-facing and outward-facing conformations. Despite extensive research efforts over the past decades, understanding of the molecular mechanism remains elusive. As these large-scale conformational movements are global and collective, we have previously performed extensive coarse-grained molecular dynamics simulations of the potential of mean force along the conformational transition pathway [J. Phys. Chem. B 119, 1295(2015)]. However, the occluded conformational state, in which both the internal and external gate are closed, was not determined in the calculated free energy profile. In this work, we extend the above methods to the calculation of the free energy profile along the reaction coordinate, d1-d2, which are the COM distances between the two sides of the internal(d1)and the external gate(d2). The potential of mean force is thus obtained to identify the transition pathway, along which several outward-facing, inward-facing, and occluded state structures are predicted in good agreement with structural experiments. Our coarse-grained molecular dynamics free-energy simulations demonstrate that the internal gate is closed before the external gate is open during the inward-facing to outward-facing transition and vice versa during the inward-facing to outward-facing transition. Our results capture the unidirectional feature of substrate translocation via the exporter, which is functionally important in biology. This finding is different from the previous result, in which both the internal and external gates are open reported in an X-ray experiment [Proc. Natl. Acad. Sci. USA 104,19005(2007)]. Our study sheds light on the molecular mechanism of the state transitions in an ATP-binding cassette exporter. 展开更多

The effects of price leadership strategies and branding strategies on the export performance of indigenous Chinese exporters with a focus on developing country markets and developed country markets are examined based on the principles of strategy-environment co-alignment and marketing segmentation theory. Findings suggest that when focusing on developing country markets, the use of a branding strategy is more likely to enhance export performance. When focusing on developed country markets, neither the use of a price leadership strategy nor the use of a branding strategy enhances export performance. Finally, theoretical and managerial implications of the findings are discussed. 展开更多

This paper evaluates the causal effect of air pollution on the share of domestic value-added in exports for Chinese exporters.Precipitation is employed as an instrument for air pollution to alleviate the endogeneity.Our baseline instrument variable estimation identifies a significant and negative effect of air pollution on the share of domestic value added in exports.Specifically,each 1 mg/m^(3) increase in yearly PM_(2.5) exposure is associated with 3.1447 units decrease of the domestic value-added rate of firms’exports.This result holds when wind speed,air flow index and thermal inversions are used as alternative instruments.Further,it is shown that air pollution is detrimental to the health of employees,and also has negative effect on firms’productivity as well as firms’innovation capacity.All of these may have a negative effect on domestic production and therefore reduce the share of value added done domestically.Lastly,greater effect is found for the central region,the east of Hu Huanyong line,cities of low altitude and high pressure,and also for foreign-invested firms.This paper provides empirical evidence that air pollution may affect the organization of global production,i.e.,the share of domestic value added in Chinese exports,and it certainly contributes to more comprehensive understanding of the effect of air pollution. 展开更多

Our research topic is about the economic situation in the Middle East and North Africa (MENA) oil exporters after the global crisis in 2008. The authors tried to find the answers to the questions such as "How bad or good is the situation there?" and "what is the expectation about the future of the region?" Like other countries around the world, the MENA oil exporters, comprised of Algeria, Bahrain, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Sudan, United Arab Emirates, Yemen were adversely affected by the global crisis. The MENA oil exporters are recently recovering from their recession in 2009 when the global crisis was felt intensively there. GDP in the region has grown by 3.5 percent in 2010 after a low growth of 0.7 percent in 2009. The average real GDP growth excluding Libya is projected to reach 4.9 percent in 2011. Two developments mark the outlook: the unrest in the region and the surge in global fuel and food prices. For most oil exporters, the expected increase in oil prices and production volumes will lead to higher growth in 2011 and stronger fiscal and external balances, notwithstanding recent increases in government spending. The oil exporters' combined external current account surplus is estimated to increase. The effects of the political events in Tunisia and Egypt have spread in varying degrees to the MENA oil exporters in the region, and many of these countries are responding with public spending and job-creation measures to alleviate social tensions. The social unrest also highlights the need to pursue fundamental economic reforms--social policy, fiscal management, governance, business environment, labor markets, and financial sector access to facilitate more inclusive economic growth. While the MENA countries are generally divided into two sub-regions such as "oil exporters" and "oil importers" in the economic literature, the authors will deal with only the MENA oil exporters in this work. The negative effects of the global crisis in these countries on growth, inflation, current account balance, budget balance, and finally financial sector will be reviewed in this work and the expectations and the developments which occurred after the crisis in these countries will be dealt with especially in the context of the IMF reports. 展开更多

As part of improving services done for various clients in all Moroccan areas, Moroccan exportation group of fruits and vegetables in collaboration with their packaging units and producers, tends to cooperate in order to face with international competitiveness. Indeed, the complexity of networks of partners has led policy-makers to implement new techniques and tools to help control different processes. For this reason, the implementation of a permanent monitoring of different operations ranging from production, packaging, and distribution of perishable products has become paramount. This article aims to propose a model of multi-agent citrus supply chain, based on indicators for monitoring and evaluation of performance of its logistics systems, in order to build a new independent, robust and responsive chain, and to optimize and control the flow of materials and information between the different actors and stakeholders of the chain. 展开更多

Developing countries establishing international branch campuses (IBCs) is an emerging trend, and currently compromises 17% percent of the market in terms of the number of IBCs. While researchers have applied different social science perspectives to analyze cross-border higher education and IBCs, they usually emphasize developed countries as exporters and developing countries as importers of higher education. The phenomenon of developing countries as exporters of higher education has seldom been looked at so far in the research. This paper first describes the current development of IBCs, then illustrates what social science perspectives have been used on this topic, followed by how push-pull theory relates to developing countries being exporters of IBCs. The paper aims to combine E.S. Lee's push-pull theory and Gu's push-pull framework to analyze the push and pull factors in their advertisement and marketing claims when higher education institutions (HEIs) from developing countries plan to establish branch campuses in foreign countries. Soochow University in Laos is used as a case study. Furthermore, intermediate barriers and solutions are also identified in this case study. However, this case study has its own uniqueness and only serves heuristic for future research. 展开更多
