China’s rapid economic growth has increased consumers’ disposable income evidently. With the improvement of living standards, Chinese people have increasingly concerned about their life quality, especially when buying consumable commodities like food, toys and clothing as well as durable...

The Kadometsev-Petviashvili (KP) and modified KP (mKP) equations are retrieved from the first two soliton equations of coupled Korteweg-de Vries (cKdV) hierarchy. Based on the nonlinearization of Lax pairs, the KP and mKP equations are ultimately reduced to integrable finite-dimensional...

The development of industrial ecology has led company managers to increasingly consider their company's niche in the regional system, and to develop optimization plans. We used emergy-based, ecological-economic synthesis to evaluate two optimization plans for the Jiufa Combined Heat and Power...

In order to help water supply utilities improve water supply management, offer early warning and control water pipeline leakage, so as to provide clean water to residents, many instruments are installed to monitor hydraulic and water quality conditions along the water pipelines. However, one of...

The mathematical expression of nonadditivity X(1 ∪ 2)=X(1) + X(2) + αX(1)X(2) has been frequently used for the development of statistical physics for nonadditive system, where X is entropy or energy, and α is hoped to be a parameter characterising the nonadditive property of the composite...

Modern random matrix theory indicates that when the population size p is not negligible with respect to the sample size n, the sample covariance matrices demonstrate significant deviations from the population covariance matrices. In order to recover the characteristics of the population...
