Cyber crime, such as theft of credentials or credit card fraud has emerged as a new type of crime in recent years. Cyber criminals usually attack Internet services to steal sensitive data and operate in crowded online underground marketplaces. Crime investigators and digital forensics are trying to detect and analyze these marketplaces. However, due to the lack of efficient and reliable methods...

Monitoring of roof activity is a primary measure adopted in the prevention of roof collapse accidents and functions to optimize and support the design of roadways in underground coalmines. However, traditional monitoring measures, such as using mechanical extensometers or electronic gauges, either require arduous underground labor or cannot function properly in the harsh underground environment...

Environment monitoring is important for the safety of underground coal mine production, and it is also an important application of Wireless Sensor Networks (WSNs). We put forward an integrated environment monitoring system for underground coal mine, which uses the existing Cable Monitoring System (CMS) as the main body and the WSN with multi-parameter monitoring as the supplementary technique. ...

Due to safety and ethical issues, traditional experimental approaches to modelling underground risk behaviours can be costly, dangerous and even impossible to realize. Based on multi-agent technology, a virtual coalmine platform for risk behaviour simulation is presented to model and simulate the human-machineenvironment related risk factors in underground coalmines. To reveal mine workers’ ris...

The underground uranium mine Königstein (Saxony, Germany), currently in the process of remediation, represents an underground acid mine drainage (AMD) environment, that is, low pH conditions and high concentrations of heavy metals including uranium, in which eye-catching biofilm formations were observed. During active uranium mining from 1984 to 1990, technical leaching with sulphuric acid was ...

• Door opening scenarios for a metro train fire were studied. A theoretical model the inner carriage smoke propagation was developed. Experiments conducted control of fire. Critical velocities and confinement two door proposed. The critical velocity, velocity back-layering length are significant factors in tunnel This research aims to analysis correlation these 3 key parameters different during...
