Grey Relational Analysis
Grey relational analysis (GRA) was developed by Deng Julong of Huazhong University of Science and Technology. It is one of the most widely used models of grey system theory. GRA uses a specific concept of information. It defines situations with no information as black, and those with perfect information as white. However, neither of these idealized situations ever occurs in real world problems. In fact, situations between these extremes, which contain partial information, are described as being grey, hazy or fuzzy. A variant of GRA model, Taguchi-based GRA model, is a popular optimization method in manufacturing engineering. Definition Let X_0=\left(x_0\left(1\right),x_0\left(2\right),\dots ,x_0\left(n\right)\right) is an ideal data set andX_k=\left(x_k\left(1\right),x_k\left(2\right),\dots ,x_k\left(n\right)\right),k\mathrmm are the alternative data sets of the same length. The Grey Relational Grade (GRG) between the two data sets is given by _=\int^n_ where the Grey Relationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deng Julong
Deng Julong (; January 1933 – June 22, 2013) was a professor of Huazhong University of Science and Technology, Wuhan, China. He is acknowledged as the founder of grey system theory, first proposed in 1982 with the publication of his paper “Control problems of grey systems,” in the international journal ''Systems and Control Letter'', edited at the time by Roger W. Brockett, a professor at Harvard University. This theory underlies the theory of grey relational analysis. His theory inspired many noted scholars like Jeffrey Yi-Lin Forrest, Liu Sifeng, and Keith W. Hipel, recipient of Izaak Walton Killam Memorial Prize.Liu, SF., Yang, Y., and Forrest, J. (2017). ''Grey Data Analysis''. Springer. Academic career The works of Professor Lotfi A. Zadeh significantly inspired Deng, and the uncertainty of the Deng Xiaoping era inspired him to work on uncertain systems. In 1965, he proposed the theory of multivariate system control. His academic paper, "an integrated approach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Information Theory
Information theory is the scientific study of the quantification (science), quantification, computer data storage, storage, and telecommunication, communication of information. The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s. The field is at the intersection of probability theory, statistics, computer science, statistical mechanics, information engineering (field), information engineering, and electrical engineering. A key measure in information theory is information entropy, entropy. Entropy quantifies the amount of uncertainty involved in the value of a random variable or the outcome of a random process. For example, identifying the outcome of a fair coin flip (with two equally likely outcomes) provides less information (lower entropy) than specifying the outcome from a roll of a dice, die (with six equally likely outcomes). Some other important measures in information theory are mutual informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Pollution
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD ...

Ren Zhengfei
Ren Zhengfei (; born 25 October 1944) is a Chinese entrepreneur and engineer who is the founder and CEO of Huawei Technologies, the world's largest manufacturer of telecommunications equipment and second largest manufacturer of smartphones. Early life * On October 25, 1944,Ren Zhengfei was born in Zhenning County, Guizhou Province. He spent his primary and junior high school in the mountain village near his home. *In 1960, there was a serious famine in Guizhou Province. At this time, Ren Zhengfei's family was starving. In order to support his family, Ren Zhengfei implemented a strict system of food distribution in his family. In order to cope with hunger, Ren Zhengfei often went to the mountains to pick wild fruits instead of grain. He always wore a single layer coat because of poverty in high school.In his third year of high school, no matter how hungry he was, he did not eat the rations of his family. Thanks to this, none of his brothers and sisters starved to death.In order t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
