In multi-hop wireless networks, maximizing network utility by joint congestion control and scheduling has drawn much research interest, and significant progress has been made that has yielded much insight. However, in attempting to maximize network utilization, most scheduling mechanisms proposed in earlier works are too complicated to be implemented in wireless devices. One traditional approach to...
The variety of encoding schemes in the modern logistics industry slows down the pace of supply chain. EPC which provides a better solution to supply chain adopts a set of identifiers to stand for manufacturers and their products. This article has analyzed many kinds of coding schemes in details and carried out transformation between other encoding schemes and EPC. A code transformation system based...
Expectations’ self-fulfillment and self-destroying co-exist in socio-economic systems, which makes the evolution of the systems seem to be mysterious to us. We regard these collective phenomenon arise from people’s ways to expect and act, namely, the expectation mode and action strategy, and propose a simple agent-based model in consideration of four direct combinations of general expectation modes...
Freight volume forecasting is significant to highway web plan. Here, support vector regression optimized by genetic algorithm (G-SVR) is proposed to forecast freight volume. We adopt genetic algorithm (GA) to seek the optimal parameters of SVR in order to improve the efficiency of prediction. The data of freight volume in a certain port from 1998 to 2007 is used as a case study. The experimental results...
Recently, each of the multifunction card systems has been continuously expanding its function, and almost to the acme. The implementation of bank campus multifunction card system has realized the multi win among banks, merchant stations, card owners and schools. However, these designs are confined to the connotative expansions of the system function, not the further optimize of the system. Furthermore,...
Contract Net is an important model based on competition mechanism to solve the collaborative problems, but exits many shortages. In this paper a negotiation strategy of multi-Agent based on extended contract net is presented to reduce the communication and negotiation time and improve the efficiency. Agent mind parameters and buffer pool are introduced to support the extended contract net. So the...
This paper considers the problem of finding a common linear copositive Lyapunov function for a set of second order systems. Based on mathematical programming, we give a new proof of the result in (O. Mason, 2004). Then we extend this result to a finite number of systems, and a common linear copositive Lyapunov function is obtained.
In order to meet the accuracy need of network users on information service, this paper introduces multi- agent feedback learning mechanism based on traditional collaborative filtering algorithms and proposes recommendation algorithm based on multi-agent. During the recommendation process, the algorithm, considering the recommended project as a recommended subject, infers autonomously whether the recommended...
SiC BJT with varying emitter width were investigated by numerical simulations as well as experiments. Emitter size effects (ESEs) are demonstrated in today's SiC BJT by comparing the characterization of BJT with different emitter width. Surface recombination current is found to be comparable with published result for heterojunction bipolar transistors (HBTs). In SiC BJT design, this effect has to...
