The dynamic programming neural-network simplex (DPNS) model, which is aimed at making some improvements to the dynamic programming neural-network (DPN) model, is proposed and used to derive refill operating rules in reservoir planning and management. The DPNS model consists of three stages....

By analyzing the present situation of reservoir flood control operation, this paper proposes multi-person multiobjective decision-making model for the problems of flood control operation. The model takes the influence of multiobjectives and experience and knowledge of decision-makers into...

The progress in wave energy technologies in China during the past decade is briefly reviewed. And the description is focused on the wave energy resource and the current status of wave energy in China. The difficulties facing wave energy developments in China are summarized. The national policy...

By testing 88 different funds of the Chinese fund market (CFM), we find fractal behavior and long-range correlations in the return series, which are insensitive to the kind of funds. Meanwhile, a power-law relationship between the deviation D of prices and the Hurst exponent H has been obtained,...

The exponential degree distribution has been found in many real world complex networks, based on which, the random growing process has been introduced to analyze the formation principle of such kinds of networks. Inspired from the non-equilibrium network theory, we construct the network...

The game ‘rock–paper–scissors’ model, with the consideration of the effect of the psychology of conformity, is investigated. The interaction between each two agents is global, but the strategy of the conformity is local for individuals. In the statistical opinion, the probability of the...

The level of service in public walking spaces is mainly determined by the differences in pedestrian traffic demand and infrastructure supply. A problem worth studying is the evacuation process in a closed square with partition wall. In this paper, a cellular automaton model is presented to...

The main topic of this paper is the study of the stationary solution of a stochastically complex dynamical system. The stochastic averaging method of quasi-Hamiltonian system, an important tool for the analysis of dynamical properties of stochastically real dynamical system, is used at the first...

This work is based on micro-structural performance of the Ti–B4C–C laser alloying coatings on Ti–6Al–4V titanium alloy. The test results indicated that laser alloying of the Ti–B4C–C pre-placed powders on the Ti–6Al–4V alloy substrate can form the ceramics reinforced hard...

Residential energy consumptions of both electricity and fuels are associated with emissions of many air pollutants. Temporally and spatially resolved energy consumption data are scarce in China, which are critical for a better understanding of their environmental impacts. In this study, a...
