In order to simulate the uncertainty associated with impression or vagueness, a decision maker may give her/his judgments by means of triangular fuzzy reciprocal preference relations in the process of decision making. The study of their consistency becomes a very important aspect to avoid a...

In this paper, we propose a theoretical entanglement concentration protocol for unknown triparticle W class states, and then the physical implementation of this proposal has also been presented in cavity QED. The general protocol is mainly based on the appropriate Bell state measurements. In the...

The interest rate and volatility may have different values in the different commercial banks and financial institutions. Moreover, the fluctuations of the underlying assets are rare events, and there are not enough historical data to estimate the jump intensity in a precise sense. This paper...

CO2 emissions of the electricity supply sector in China account for about half of the total volume in the country. Thus, reducing CO2 emissions in China’s electricity supply sector will contribute significantly to the efforts of greenhouse gas (GHG) control in the country and the rest of the...

This study proposed a polygeneration system based on coal partial gasification, in which methanol and power were generated. This proposed system, comprising chemical and power islands, was designed and its characteristics are analyzed. The commercial software Aspen Plus was used to perform the...

The distribution of energy and industry in China is extremely uneven. The western region is rich in energy resources but relatively economically backward, while the eastern region, particularly, the southeast coastal area, is an industrially-developed area but is short of energy resources. On...

In this paper, the phase transition characteristics of CO2 and CO2/H2 mixture are analyzed, and ideas for improving the cryogenic separation method are drawn. On this basis, a novel CO2 cryogenic liquefaction and separation system is put forward. In the novel system, two-stage compression,...

Retrofitting existing power plants for CO2 capture poses numerous constraints. The layout of the original process and the structure of the existing equipment cause various special problems in the design process as well as influence system performance. In view of these, this paper carries out...

Double reheat steam systems have been receiving more attention because of the rapid development of ultra-supercritical power plants. In this study, the thermodynamic analysis and design optimization of a double reheat system in an ultra-supercritical power plant are comprehensively conducted....
