The steel industry represents about 7% of the world’s anthropogenic CO2 emissions due to high use fossil fuels. CO2-lean direct reduction iron ore with hydrogen is considered offer a potential reduce emissions, and this Fe2O3 powder investigated in research. H2 reaction kinetics fluidization characteristics fine cohesive particles were examined vibrated fluidized bed reactor. A smooth bubbling ...

Workflow management technology requires the existence of explicit process models, i.e. a completely specified workflow design needs to be developed in order to enact a given workflow process. Such a workflow design is time consuming and often subjective and incomplete. We propose a learning method that uses the workflow log, which contains information about the process as it is actually being e...
