In this article, we present a simplified isotopic Atmospheric Water Balance Model (iAWBM), to simulate spatial distribution and temporal variations of δ18O in atmospheric vapour and in precipitation, and the correlations of δ18O in precipitation with precipitation amount and with temperature. This method overcomes deficiencies of the Global Network of Isotopes in Precipitation (GNIP) due to its limitation...
Based on the theory of fuzzy neural network and hierarchical intelligent control, establish system architecture of freeway multi-ramp control, put forward coordination control algorithm of multi-ramp, provide a systemic solution method to realize multi-ramp intelligent control. This method is relatively simple and easy to expand, simultaneity independent on specific freeway mathematical models, possess...
In this paper, we propose a realistic resource sharing protocol for VANET. The main idea of our protocol comes from typhoons. Typhoons move according to their eyes' mobility, i.e., quorums which are responsible for a given resource holder/requester "moves" according to the resource holder's/ requester's mobility. Our protocol exploits spatial locality between requesters and resource holders...
In order to avoid the resource inefficiency of all-participated cooperation in wireless amplify-and-forward relay networks, a novel relay selection scheme based on the channel gain of the source-relay and relay-destination links is proposed. A condition is introduced to maximize the upper bound of the overall received signal-to-noise ratio (SNR). The relay nodes which have bad channel conditions are...
In this paper, we propose a new relay selection scheme based on the channel gain of the source-to-relay and relay-to-destination links to maximize the upper bound on the overall received signal-to-noise ratio (SNR). In order to reduce the complexity of the scheme, we assume that each of the selected relays is allocated identical power. The total power is reasonably allocated between the source and...
Solidification model is developed based on control volume method for steel continuous casting process, which is nonlinear and non-differential, and parameters of convective heat transfer coefficient for each segment of the secondary cooling zone are ascertained, a new hybrid particle swarm algorithm (CPSO) is introduced to improve the optimizing performance by embedding the chaotic search in the particles...
