A Brief History of Mine Ventilation
Observations of the movements of air in underground passages have a long and fascinating history. Between 4000 and 1200 BC, European miners dug tunnels into chalk deposits searching for flint. Archaeological investigations at Grimes Graves in the south of England have shown that these early flint miners built brushwood fires at the working faces—presumably to weaken the rock. However, those Neo...

متن کاملEvaluating functional network inference using simulations of complex biological systems
MOTIVATION Although many network inference algorithms have been presented in the bioinformatics literature, no suitable approach has been formulated for evaluating their effectiveness at recovering models of complex biological systems from limited data. To overcome this limitation, we propose an approach to evaluate network inference algorithms according to their ability to recover a complex fu...
متن کاملMethod for Evaluating Innovative Mine Detection Systems
Researchers in physical, chemical, and biological sciences are studying and developing methods that could reduce the false alarm rate and maintain or increase the probability of detection for mine clearance. New detection concepts involve searching for characteristics other than mine metal content. A variety of techniques that exploit properties of the electromagnetic spectrum are being explore...
متن کاملMine Countermeasures Requirements To Support Future Operational Maneuver
istorically, the Navy’s mine countermeasures ships and helicopters were designed for Cold War applications, which emphasized clearance of our own ports and gave amphibious assault low priority. Today’s naval mission requires regional contingency operations where friendly forces must be capable of projecting power ashore. For example, the attempted assault of Kuwait during Desert Storm by the U....
