The treatment of chromium containing wastewater using chitosan and the modified chitosan as adsorbents was studied. Various factors including solution pH, the dosage of absorbents and initial Cr (VI) concentrations were taken into account and promising results obtained. The results showed that the modified chitosan have a better efficiency on the removal of Cr (VI).an initial solution PH of 1.0 was...
Both coagulation and SBR are effective techniques for treatment of papermaking wastewater. In this paper, the removal efficiencies of COD in papermaking wastewater are investigated by the processes of coagulation, SBR and coagulation-SBR combined processes. The effects of coagulant type, the dosage of coagulant, pH and stirring rate on treatment efficiency are explored in the paper. The results showed...
Sequential pattern mining is of great importance in many applications including computational biology study, consumer behavior analysis, system performance analysis, etc. Recently, an extension of sequential patterns, called time-interval patterns, is proposed by Chen, Jiang, and Ko, which not only reveals the order of items but also the time intervals between successive items. Based on the time-interval...
The Acupuncture Expert (AcuXpert) is the first Intelligent Computer-Aided Learning (ICAL) system in the science of acupuncture and moxibustion in the world. There are two purposes for the development of such a system: the first is to teach students the principles and concepts of the science of acupuncture and moxibustion; the second is to instruct acupuncturists to make correct diagnoses, employ...
