In order to apply the traditional traffic assignment model in the actual network, firstly this paper distinguishes the impact of intersection delay between different steering on traffic assignment by changing the topology of network. Secondly this paper presents a modified dijkstra algorithm based on the changed topology of network and presents a modified traffic assignment algorithm based on the...
An extracellular biopolymer (PS-2) produced by Pseudomonas fluorescence C-2 was used as an alternative biosorbent to remove toxic Pb(II) metallic ions from aqueous solutions. The prepared biosorbent PS-2 were characterized by FTIR and SEM. The effect of experimental parameters such as pH, dosage of biosorbent , Pb(II) initial concentration and contact time on the adsorption was studied. It was found...
