This means that the harm principle is not in fact Mill's only principle because we cannot decide whether regulations that would prevent harm should be adopted without appealing to the principle of utility But even if harm prevention is not sufficient to justify restricting liberty Mill does appear to claim that it is necessary Sometimes Mill suggests that the harm principle is equivalent

Two fault conditions were simulated a faulty particle size analyser on the product stream (PSE fault) and rapid wear of the mill liner (mill liner fault) The mill circuit simulation and simulated fault data have been made available for further research such as testing other fault detection and diagnosis methods or investigating the economic impact of fault detection in more detail

Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants The traditional data-driven 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
