Deep eutectic solvents (DESs), a novel category of sustainable solvents, are expected to achieve the design of the chemical processes without utilizing or generating harmful chemicals. In this work, based on the mathematical model inspired by the transition state theory, the group contribution method is used to accurately predict the viscosity of DESs. The model is constrained by Eyring rate theory...
Compared with bistatic RCS, the monostatic RCS calculation is more difficult for the needs of surface current on scatterer induced by the incident wave of every single angle, so the calculation burthen is very large. Based on the character of "coefficients matrix of FDFD equations is invariable whether the angle of incident wave was changed", this paper proposes a fast algorithm for monostatic...
With the increasing numbers of Web services and service users on World Wide Web, predicting QoS(Quality of Service) for users will greatly aid service selection and discovery. Due to the different backgrounds and experiences of users, they have different QoS experiences when interacting with the same service. Even two users who have similar experiences on some services can have diverging views when...
As one of the traditional service industries, catering industry is experiencing the important development period of brand extensions. Customer satisfaction affects corporation economic efficiency and competitiveness. The paper presents six factors impacting the customer satisfaction basing on the literature reviews and in-depth interviews with consumers. The questionnaire found that the restaurant...
Adsorption-desorption behavior of copper in Sichuan mine soils was studied using the batch method. The measured copper adsorption data was described by the Langmuir equation and the Freundlich equation respectively. The results indicated that the Freundlich equation was less suitable than the Langmuir equation to describe the adsorption data. In contrast to copper adsorption, the amount as well as...
Traditional trading methods are based on the integrated optimization problems of economy and environmental protection, but do not consider the effects on demand-side. A revised model for medium and shortterm trade planning is presented in this paper. It firstly forecasts the industry electric quantity of peak, flat, valley monthly on the demand side using the parameter-modified grey model and consider...
In recent studies, the lifetime of Wireless Sensor Network(WSN) has been paid more and more attention to in order to evaluate the network performance. To save energy on software level, sleep scheduling plays a very important role and how to predict the time period when a mote can go to sleep mode is an essential technology. In this paper, a predicting model is proposed as a preliminary study to do...
A three-dimensional pore diffusion model describing sorption process was presented by considering the effects of the temperature and non-linear sorption isotherm. The model numerically simulates the scenario with the boundary conditions fluctuating in both step change and parabolic change. The rule of variation of temperature and concentrations with sorption time is figured out, and also the comparison...
Industrial cluster has the function of risk sharing. And this paper may use the mathematical model to analyze the whole cluster's procurement strategy including the optimal quantity of the forward contracts. Considering the pricing of the forward contracts in the floating interest structure, this paper makes further analysis on the decision model of the whole cluster. Through the conclusion from the...
A new combined BP neural network model based on accelerating genetic algorithm is put forward in this paper. On the foundation of traditional BP neural network, this method is given better iteration values improved by accelerating genetic algorithm, thus and increase iteration rate and avoid sinking into local minimum. Then, it is applied to forecast the heat load in a certain area, and compared with...
