[] Control flow anomaly detection by process mining

2 ·The business processes of organizations may deviate from normal control flow due to disruptive anomalies including unknown skipped and wrongly ordered activities To identify these control flow anomalies process mining can check control flow correctness against a reference process model through conformance checking an explainable set of algorithms that

Evaluating the impact of auxiliary fan practices on localised

·With increasing mine depth there is a subsequent increase in the airflow demand and system pressure [4] These pressure demands become a concern when surface extraction fans can no longer supply the required suction pressure which ultimately restrains mine expansion [4] Therefore the use of smaller underground auxiliary fans is commonplace in deep level
