QoS routing is one of the key issues in the research of the overlay network. This paper proposes a routing algorithm with Multiple Constrained Balanced Path(MCBP) based on analyzing multiple QoS constraints. It solves the weights allocation among multiple QoS constraints by introducing the methods AHP and Parameter Normalization with including multiple QoS parameters of nodes and links considered...
Sludge-glass ceramic particles were used as filter media for single biological aerated filter (BAF) to treat dairy wastewater in this study. Seed sludge was inoculated from Zhengzhou Wulongkou wastewater treatment plant. When bio-film was promoted and the effluent contamination removal rates above 40% after one week's operation, started to optimize the operation parameters such as pH, hydraulic retention...
Focused all the attention on survivability schemes under the high speed, multi-service and integrated multi-domain optical networks (MDON) environment. In this paper, based on the traits which are multi-service and distributed control for optical network, we first analyze the problems and challenges posed by MDON survivability. According to the survivability need of MDON, we classify associated key...
Three efficient COD degrading bacteria were screened in the aeration tank of Zhengzhou Wulongkou municipal wastewater treatment plant by conventional isolation and purify methods. One of them (the isolate 4#) was short-rod-shaped, gram negative and the 16S rRNA sequence showed that it is closely related to Acinetobacter. The isolate 18# was rod-shaped, gram negative and the closest relative is Escherichia...
This paper proposes a GMPLS survivability scheme based differentiated services. This algorithm which is based on three normal GMPLS survivability scheme models (namely global protection, reverse backup and local repair) chooses evaluation function to decide in advance most suitable restoration model for working path of each kind of traffic, then only employs it to calculate the backup path of working...
