Treated effluent discharge from uranium (U) mines and mills elevates the concentrations of U, calcium (Ca), magnesium (Mg), and sulfate (SO4 (2-) ) above natural levels in receiving waters. Many investigations on the effect of hardness on U toxicity have been experiments on the combined effects of changes in hardness, pH, and alkalinity, which do not represent water chemistry downstream of U mi...

A mine is basically a weapon that can't move and can only attack a target by blowing itself up, a rather primitive approach to warfare. Being required neither to move nor to project power at a distance, mines are relatively cheap; a mine may cost thousands of dollars while a missile or torpedo of equivalent destructive power would cost hundreds of thousands. Being cheap and available on the int...

In this paper five different sensor data fusion options for the detection of anti-personnel land-mines are presented. The performance of these options are evaluated in a case study of estimated figures for mines and possible false alarm generating objects. Dempster-Shafer with proper mappings and rule based fusion provided the best result and an improvement over single sensor solutions.

Experimental and theoretical results are presented for ultra wide-band (UWB) synthetic aperture radar (SAR) signatures of buried anti-tank and anti-personnel mines. Such are characterized by resonancelike peaks as well as valleys, across the 50–1200 MHz bandwidth considered. Consequently, frequency subbanding is used to highlight one target over another, of application to discriminating targets...

This paper introduces a statisticallywell-founded evaluation of the fusion of dual-band infrared and tri-band visual imagery for detecting buried land mines using real-data. A unified Bayesian framework is presented for representing and inferring from data captured by multiple sensors of scenes that may contain buried land mines.

Spontaneous combustion of coal is one of the most horrifying hazards in coal industries, especially in underground coal mines. Thus having a prior knowledge about the occurrence of this phenomenon in underground coal mines is of crucial importance in preventing this process, loss of life, huge economic loss, and environmental pollution. The aim of this work is to determine the spontaneous combu...
