A significant fraction of short fibers commonly called "reject fines" is produced while recycling wastepaper at paper mills producing linerboard. These fines are usually rejected into the solid waste stream that further requires land filling and poses environmental problems. The major component of these rejects is cellulose that can be a potential source of fermentable sugars for biofuels ...

Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional datadriven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system ...
