The Maclaurin symmetric mean (MSM) was originally introduced by Maclaurin. The prominent characteristic of the MSM is that it can capture the interrelationship among the multi-input arguments. However, the researches on MSM are very rare, especially in fuzzy decision making. In this paper, we investigate the MSM operator and extend the MSM operator to interval-valued intuitionistic fuzzy environment and develop the interval-valued intuitionistic fuzzy Maclaurin symmetric mean (IVIFMSM) operator. Some desirable properties and special cases of IVIFMSM operator are discussed in detail. Based on IVIFMSM operator, an approach to multiple attribute decision making problems with interval-valued intuitionistic fuzzy information is developed. Finally, an illustrative example for online advertising publisher evaluation is given to verify the developed approach and to demonstrate its practicality and effectiveness. © Copyright 2016 American Scientific Publishers All rights reserved.

Inspired by the generalized entropies for graphs, a class of generalized degree-based graph entropies is proposed using the known information-theoretic measures to characterize the structure of complex networks. The new entropies depend on assigning a probability distribution about the degrees to a network. In this paper, some extremal properties of the generalized degree-based graph entropies by using the degree powers are proved. Moreover, the relationships among the entropies are studied. Finally, numerical results are presented to illustrate the features of the new entropies. © 2017 by the authors.

With the rapid development of intelligent buildings, a lot of researchers have found that it is difficult to establish mathematical model when the problem that energy-saving in water supply system of an intelligent building tank is focused, because that the outflow of the tank volume is volatile when the water is daily living water. In this paper, fuzzy control theory is used to establish a fluid level, and the fluid input flow rate to determine the amount of control, which to push the valve's opening size and speed in order to control the water supply valve opening adjustment level, so that the liquid position of container maintains a constant, and the MATLAB software is used to verify the effect of fuzzy control system. The results show that in this fuzzy control system the benefits of economic operation of water supply can be ensured by ensuring a constant level of liquid. ©2011 ACADEMY PUBLISHER.

This article compares the new ambient quality standards adopted by China on 29 February 2012 with the previous ambient air quality standards and reveals the significance of and reasons for this revision. It points out that the new ambient air quality standards added fine particulate matters into the items to be monitored, reclassified monitored items into the group of basic items to be mandatorily monitored nationwide and the group of other pollutants to be monitored discretionally, and set the maximum concentration for each of the two categories of areas. This revision was in response to the demand of the general public for less pollution and better information on the air quality. This revision is important for the human health because it imposes a new task on local governments. The new standard shall be implemented gradually, beginning with most seriously polluted areas, and finally to be implemented nation-wide. This revision is expected to contribute to better protection of human health. © (2013) Trans Tech Publications, Switzerland.

After years of rapid economic development, environmental pollution has become a big concern to the general public in China. Numerous mass protests happened because of actual or perceived environmental pollution. This article makes a case study of three recent mass protests to find the features and deeper causes of mass protests for environmental issues. It concludes that, without sufficient information disclosure, the general public may still protest and the government may yeild, even if a project followed all governmental procedures and obtained all governmental approvals. This harms both the credibility of the government and the economy, and eventually the interests of the public. Chinese government has found the deeper causes and is working on the right direction. © (2013) Trans Tech Publications, Switzerland.

Heterogeneous data produced by Internet of Things increased continually. Inconsistent semantics of data became obstacle of sharing data. To handle them effectively and intelligently, a semantic model for Internet of Things was proposed, which was based on semantic technology and cloud computing. Scalable distributed file system was the basis of storing mass data. Distributed inference engine, which was based on Map/Reduce operation model, had solved the problem of reasoning on mass ontology. Hierarchical semantic provided the basis of intelligent processing, which had reached consistent understanding between heterogeneous data. Global ontology laid emphasis on solving interoperation, local ontologies laid emphasis on personalized knowledge.

This contribution deals with the FastICA algorithm in the domain of Independent Component Analysis (ICA). The focus is on the asymptotic behavior of the generalized symmetric variant of the algorithm. The latter has already been shown to possess the potential to achieve the Cramér-Rao Bound (CRB) by allowing the usage of different nonlinearity functions in its implementation. Although the FastICA algorithm along with its variants are among the most extensively studied methods in the domain of ICA, a rigorous study of the asymptotic distribution of the generalized symmetric FastICA algorithm is still missing. In fact, all the existing results exhibit certain limitations. Some ignores the impact of data standardization on the asymptotic statistics; others are only based on heuristic arguments. In this work, we aim at deriving general and rigorous results on the limiting distribution and the asymptotic statistics of the FastICA algorithm. We begin by showing that the generalized symmetric FastICA optimizes a function that is a sum of the contrast functions of traditional one-unit FastICA with a correction of the sign. Based on this characterization, we established the asymptotic normality and derived a closed-form analytic expression of the asymptotic covariance matrix of the generalized symmetric FastICA estimator using the method of estimating equation and M-estimator. Computer simulations are also provided, which support the theoretical results. © 1991-2012 IEEE.

Semilinear stochastic dynamic systems in a separable Hilbert space often model some evolution phenomena arising in physics and engineering. In this paper, we study the existence and uniqueness of mild solutions to neutral semilinear stochastic functional dynamic systems under local non-Lipschitz conditions on the coefficients by means of the stopping time technique. We especially generalize and improve the results that appeared in Govinadan (2005), Bao and Hou (2010), and Jiang and Shen (2011). © 2013 Feng Jiang.

PM2.5 has gradually become a major environmental problem of China with its rapid economic development, urbanization, and increasing of motor vehicles. Findings and awareness of serious PM2.5 pollution make the PM2.5 a new criterion pollutant of the Chinese National Ambient Air Quality Standard (NAAQS) revised in 2012. The 2012 NAAQS sets the PM 2.5 concentrate limitation with the 24-hour average value and the annual mean value. Wuhan is quite typical among central and southern China in climate, economy, development level, and energy consumption. The data are cited from the official website of Wuhan Environmental Protection Bureau and cover the period from 1 January to 30 June 2013. The data definitely confirm the existence of serious PM2.5 pollution in Wuhan and indicate that the addition of PM2.5 as a criterion pollutant significantly brings down the attainment rate of air quality. The example of Wuhan reveals that local governments should take measures to reduce the emission of PM2.5 if it affects the attainment rate and the performance evaluation value of air quality. The main contribution of 2012 NAAQS is that it brings down the attainment rate of the air quality and forces local governmental officials to take the measures accordingly. © 2014 Mingqing You.
