We analyze two production ways of manufacturers: costly green production and less expensive non-green production. The former emits less green house gas, while the latter does more harm to global warming. We suppose there are three possible production strategies for a manufacturer: low cost production, dual production, and green mass market production. With an assumption that “green” consumers are...
Ipv6 transition becomes urgent problem restricting the evolution of Internet. A large number of mechanisms were proposed to solve transition problems. Especially, transition methods with IPv4 over IPv6 tunnel in IPv6 access network have been discussed intensely in IETF softwire working group recently. Many 4pver6 mechanisms including stateful and stateless solutions have been proposed. This paper...
Because switching frequency of the fixed band hysteresis current controller varies greatly, it is more difficult to design the output filter. Although variable band hysteresis control can achieve fixed switching frequency, it requires more processor resources when it is actualized by software. This paper analyzes the changing patterns of switching frequency by transient current equation, and replaces...
A maneuver target interception algorithm based on multiple model adaptive estimator (MMAE) is researched and a modified differential game guidance law is given. The efficiency of this simplified MMAE algorithm lies mainly in the exploitation of the special structure of the evader maneuver command hypothesis space to reduce the number of MMAE elemental filters running in parallel and to realize the...
An all-attitude estimation algorithm for low cost attitude and heading reference system using extended Kalman filter based on modified Rodrigues parameters is designed. Aiming at the shortage of redundancy when using quaternion to describe attitude, modified Rodrigues parameters which are a three-dimensional independent vector are proposed for attitude representation. By switching between the modified...
The paper builds the reliability evaluation model of distribution generation with the random power output characteristics, based on island operating mode, analyses how to calculate the island probability, then combined with proposed method of literature, obtains the distribution network reliability index considering distribution generation with the random power output characteristics. Finally the...
